How to enhance the adhesion of nylon and glass fiber workpiece surface spray?

The need for nylon plastic to enhance adhesion is more common in its surface oil spray processing technology, and it is necessary to make the paint firmly adhere to the surface of the nylon material to have enough interlayer adhesion support, otherwise poor adhesion will lead to the paint falling off or the adhesion test paint falling off after spraying. A common solution in the spraying industry is to apply a nylon treatment in the form of a primer to enhance adhesion.

Shizukawa nylon treatment agent is a primer-type adhesion additive, which is different from the additive type of adhesion promoter, which is directly applied to the surface of the substrate by spraying, and by improving the surface polarity and wetting ability of the nylon substrate, and at the same time promoting the chemical bonding with the paint, so its adhesion enhancement effect is better than that of the additive type, and there is a mature solution to the difficult adhesion problem.

The advantage of Shizukawa Chemical Nylon Treatment Agent to enhance the adhesion of nylon spray paint is that in terms of construction technology, it adapts to the entire spraying process, combined with the pretreatment construction process, and carries out the primer operation; For the applicability of paint, there is no choice for paint, that is to say, it improves the interlayer adhesion between the substrate and the paint, so the main role is in the substrate, so ordinary color paint, UV paint, rubber paint, PU paint, etc. are equally suitable; The same is true for the substrate, not only the pure nylon substrate, but also the modified nylon material has the same effect; It is also worth noting that not only the oil injection process can also enhance the adhesion between the substrate and the glue in the adhesive process.

The surface energy of nylon plus glass fiber substrate is low, especially after adding glass fiber, the structure and molecular properties of the material change, and the difficulty of paint adhesion to the surface of the substrate during oil injection processing has become an important factor affecting the quality of coating.

The effective solution to the problem of poor adhesion on the surface of the nylon plus glass fiber workpiece is to spray a layer of Jiongsheng nylon plus glass fiber adhesion treatment agent and then spray the paint, and firmly combine the substrate with the paint through intermolecular force and mechanical occlusion, and can successfully pass the adhesion test such as 100 grids.

Jiongsheng nylon treatment agent is suitable for nylon and nylon plus glass fiber substrate spray plastic paint, PU paint, rubber paint and UV paint, etc., and is widely used in toys, small household appliances, etc.

In various industries, in order to increase the willfulness of nylon, glass fiber will be added to increase hardness and improve surface tension, and at the same time, when the nylon material with glass fiber is sprayed on the surface, it will cause the topcoat to fall off easily and not oily, so that it can not meet customer requirements.

Jingchu nylon treatment agent is synthesized by polymer, and the principle is that Jingchu nylon treatment agent can effectively disrupt the arrangement of surface molecular groups, increase its dyne value, and efficiently improve the adhesion of nylon material. The principle is that the primer properly dissolves the swollen nylon surface, and then half of the nylon resin is embedded in the nylon surface, and the other half is exposed to bind to the paint.

Jingchu nylon treatment agent has adhesion to the surface of pure nylon, nylon plus glass fiber, nylon plus carbon fiber, nylon plus PPE and other materials, and can solve the problem of surface coating adhesion such as UV, PU and rubber oil for paint applicability.

To treat the surface of the nylon workpiece first, spray a layer of treated water first, and the adhesion will be very good.

Spray a layer of nylon treatment and you're good to go.

Nylon fiber is a nylon material reinforced by glass fiber, which has good mechanical properties, dimensional stability, heat resistance, low temperature resistance and wear resistance.

Poor painting is a very common phenomenon in the spraying industry, and it is not uncommon for nylon or nylon plus glass fiber to have paint loss problems. The main manifestation of the paint peeling problem must be the paint peeling off or the adhesion test can not pass, find the cause of it, exclude the factors that we can control, such as spraying environment, construction technology, paint and other factors, but also from the substrate, nylon or glass fiber nylon belongs to the substrate with high crystalline and low surface energy, and the activity of the polar group is not strong, so it is necessary to solve the problem of paint peeling by activating the surface of the substrate and improving the adhesion and bonding strength between it and the paint.

The main solution to improve the surface adhesion environment of nylon or glass fiber nylon is to spray the nylon fiberization treatment agent on the substrate after cleaning and cleaning by priming, and the cleaning must be done at this time, because oil stains and other weak interface layers will be formed. The topcoat or primer is then sprayed directly, and the middle layer of the nylon surface treatment agent promotes the adhesion of each other, improves the substrate, strengthens the chemical bonding with the fiber paint, and forms a coating that is strong and paints wide vertical celery.

The effective method of improving the adhesion of the surface spraying paint (rubber paint, PU paint, ordinary color paint, UV paint) on the surface of nylon material is the Jiongsheng Nixiang dust dragon treatment agent, which dissolves the surface of the swollen nylon material through the solvent and embeds it in the Jinju Zen material, and the other half is exposed and combined with the surface paint to improve the adhesion between the substrate and the paint layer, solve the phenomenon of paint loss, and the adhesion test of 100 grids reaches 5B.

Summary. Hello, if you solve the nylon surface treatment, the way to enhance the adhesion of the paint is to put a layer of treatment agent on the surface before the nylon material is sprayed, that is, nylon oil-spraying adhesive to improve and improve the adhesion between the paint and the surface of the nylon material! By spraying this treatment agent on the surface of the nylon material, and then testing the sample with other products, it is found that the nylon oil-spraying adhesive has a very obvious effect on the improvement of the adhesion between the nylon material and the paint, and the sample measured by the nylon oil-spraying treatment agent can still reach 5B after the test of 100 grids, high and low temperatures, and boiling, so as to clearly confirm that the adhesion between the nylon oil-injected adhesive and the paint (PU varnish, UV varnish, plastic paint, etc.) is very clear. Moreover, it is also relatively easy to operate, and can be used in the production of nylon surface injection.

How to solve the problem of nylon surface treatment to enhance paint adhesion?

Hello. Hello, if you solve the nylon surface treatment, the way to enhance the adhesion of the paint is to apply a layer of treatment agent on the surface before spraying the nylon material, that is, nylon oil-spraying adhesive to improve and improve the adhesion of the paint and the surface of the nylon material! By spraying this treatment agent on the surface of the nylon material, and then testing the sample with other products, it was found that the nylon fuel injection adhesion effect on the adhesion of the nylon material and the paint is very obvious, and the sample measured by this nylon fuel injection treatment agent can still reach 5B after the test of 100 grids, high and low temperatures, and boiling, so as to clearly confirm that the adhesion between the nylon oil injection adhesion agent and the oil tank dust paint (PU varnish, UV varnish, plastic paint, etc.) is very clear. Moreover, its operation is also relatively convenient, and it can be used in the production of nylon surface spray stool Zen oil.

One: Corona treatment

The materials for corona treatment are limited, only the parts with simple shapes are effective, the treatment efficiency is low, and the effective time is short, because corona is related to the surrounding air, and the process changes with time and place. Complex shapes are difficult to handle due to the difference in the distance between the handling and the electrode. The arc is the usual air discharge system (corona), heat and electricity can damage the covered material.

Corona must be treated to eliminate ozone generated during operation, plasma treatment requires a special environment and vacuum, the treated material needs to be thoroughly cleaned, and the surface accumulates electrostatic charges that can hinder production.

Two: Flame treatment

Flame treatment has many advantages over other major methods such as corona treatment for large areas of polymer, including no backside treatment, no pinholes, no ozone products, and better anti-aging properties. However, the effect is not good for plastic products with complex shapes, and the processing process is long and the cost is high. At the same time, when ultraviolet (UV) irradiates the surface of plastics, its optimal parameters are difficult to obtain, and if it deviates from the optimal irradiation conditions, the surface of plastic products may decompose, melt and ablate.

In addition, UV lamps can only produce functional groups, such as liquids or gases, in special atmospheres, without ablation, and the main effect is to generate a thin amorphous layer on the surface.

Three: nylon treatment agent

Shizukawa nylon treatment agent is mainly used in the surface process treatment of resin coatings such as paints and adhesive primers or bonding products, and the effect in the bonding process is to solve the phenomenon of poor bonding and degumming by improving the adhesion between the substrate and the glue, and in the paint spray processing technology, it is to improve the adhesion between the substrate and the paint coating, and pass the test of 100 grids.

Adhesion promoter as a primer, that is, with adhesion promoter or its solution as a primer as the substrate surface pretreatment or primer, after cleaning the surface of the substrate, and then spray a coating of Jiongsheng adhesion promoter, and then carry out the paint spraying process on it, because it directly acts on the interface between the paint and the substrate, it can often achieve a good adhesion effect, and is widely used in the surface painting process of metal and other materials.

After practical production and application, we will find that physical methods such as flame treatment, ultraviolet treatment, plasma treatment, grinding treatment and other methods are more complex and the production cost is relatively high, so the painting industry generally does not use these processes. In actual production, chemical treatment methods such as solvent cleaning treatment, nylon treatment agent and other methods are more practical, simple to operate, convenient and low cost, and are generally used in the industry. In the coating process of nylon substrate, Shizukawa nylon treatment agent has a special functional group, which can effectively combine with the polar group on the surface of the substrate to produce a high adhesion layer, and the paint plays a good priming role, the principle is that the solvent properly dissolves and swells the nylon surface, and then half of the special polymer nylon resin is embedded in the nylon surface, and the other half is exposed and combined with the paint on the spraying.

The reason for the poor adhesion of nylon surface is that the polarity of the nylon surface is low, and the crystal structure makes it difficult to adhere to paints and coatings.

Solution: Use nylon treatment agent as a primer to increase nylon substrate and paint.

Interlayer adhesion between coatings. Jiongsheng nylon treatment agent is halogen-free and environmentally friendly, which can effectively improve the surface hydroxyl group of modified nylon and improve the adhesion performance of paints and coatings. The use of nylon treatment agent can pass 100 grids, high and low temperature, boiling and other tests, and the adhesion can reach 5B, so it shows that the nylon treatment agent can perfectly solve the problem of poor adhesion of nylon materials and unsatisfactory effect.

Usually in the surface coating process of plastic materials such as nylon, the role of paint is to provide decoration, and at the same time, different paints provide protection needs for different types of substrates, so the formula of the coating also needs to provide effective adhesion to a certain extent. If the adhesion performance of the paint is insufficient to meet the needs of the use environment, the overall coating can be better applied through the way of nylon adhesion enhancer and chemical surface treatment, and has better weather resistance, water resistance and chemical corrosion resistance.

In the treatment process of nylon material surface painting, different effects use different paints, such as ordinary paint, rubber paint, UV paint, PU paint, etc., Shizukawa nylon treatment agent has a wide range of compatibility with paint, generally does not take into account the factors of paint, mainly for the substrate and settings, so it is more suitable for different paint processes, reducing the influencing factors brought by paint, unless a specific adhesion test is required, such as high temperature, wear resistance, etc., the paint itself also needs to meet the resistance requirements.

Shizukawa nylon treatment agent is a surface treatment agent generally contains two groups with different properties, one functional group can be well combined with the surface of nylon or nylon and glass fiber material, and the other functional group can be well combined with paint coating, generally speaking, it seems to be a medium to promote mutual adhesion, used in the field of coating and glue, which can make paint or glue firmly attached to the surface of the material, and is widely used to solve the problem of paint peeling or degumming on the surface of nylon series materials.

The purpose of nylon and other plastic surface pretreatment agents is to solve the problems of poor adhesion caused by small polarity, high crystallinity, low surface tension, poor wettability, and smooth surface of plastic surfaces through physical or chemical enrichment.

The surface treatment process is one of the key technologies for surface spraying of plastic products. The quality of treatment directly affects the adhesion between the coating and the substrate and other technical indicators, especially for the coating treatment of plastic surfaces such as nylon. The current methods to improve the adhesion of nylon or modified nylon are:

Flame method, plasma or violet light treatment, strong acid corrosion method, corona, etc., are all aimed at improving its molecular structure to enhance adhesion to coatings. However, these methods require complex equipment and increase the cost of spraying. The selection of special adhesion treatment agents and reasonable processes can make the surface treatment simple and easy.

In the spraying process of UV, PU, rubber paint, plastic paint, ordinary paint and other materials on the surface of nylon and other materials, the function of nylon treatment agent has been well played, which improves the interlayer adhesion between nylon and nylon plus glass fiber materials and the coating system, and provides a good solution for the problem of nylon spraying paint off as a pre-treatment for nylon spraying.

The nylon adhesion treatment agent developed by Jiongsheng treatment agent is simple to use, wipe the nylon material to be treated, and remove residual grease or release agent on the surface. Spray or wipe the Jiongsheng nylon treatment agent (nylon bottom water) on the nylon material to be processed to the dry film for 5-10um, let it stand for 5-10 minutes, coat the ink or paint, let it stand for 5-10 minutes, and dry the coated workpiece at 80 for 30 minutes.
