What should I do if it is difficult to get oiled with glass fiber nylon plastic oil injection?

Nylon plus glass fiber can increase the tensile strength and bending strength of plastics, improve the heat deflection temperature, improve the modulus of the material, and reduce the shrinkage rate of the material. The low polarity of the surface of glass fiber nylon, combined with the crystal structure, makes it difficult to adhere to paints and coatings. Shizukawa nylon adhesion treatment agent can improve the surface dyne value of modified nylon and improve the adhesion of paints and coatings to substrates.

Shizukawa Chemical Nylon (plus glass fiber) treatment agent, in the test of over 100 grids, high and low temperature, boiling, etc., the adhesion can reach 5B, which can well solve the problem of poor adhesion of nylon material and unsatisfactory effect. Moreover, it is also relatively convenient to operate, and can be applied to the production of nylon surface oil injection, which simplifies the spraying process on the one hand, and improves safety and stability on the other hand.

Shizukawa nylon and glass fiber treatment agent is easy to use when spraying by hand or automatic line spraying. After spraying nylon bottom water, it is best to bake at 60 degrees for 5 minutes, if there is no condition, you can also spray it wet. In short, try to use it according to the conditions of the project.

Physical Properties:1.Chemical composition: polymer interfacial polymer.

2.Density (g cm3): .

3.Flash Point: Approx. 12.

4.Appearance: Light yellow transparent liquid.

How to use:1.Clean the nylon material to be processed, remove surface residues, etc.

2.Spray Shizukawa nylon treatment agent on the material to be treated until the dry film is 5-10um.

3.Spray ink or paint.

4.The sprayed workpiece is forced to dry at 80 degrees for 30 minutes.

Nylon fiber is added to increase the surface hardness, but also to increase the difficulty of painting, generally need to play nylon treatment agent to solve the problem of paint spraying.

There are three main reasons for the poor adhesion of nylon and glass fiber oil injection:

1.The nylon plus glass fiber substrate is not cleaned and cleaned before spraying, resulting in the formation of a weak interface layer of dirty substances such as oil or dust, and the insufficient wetting effect between the paint and the substrate.

2.Due to the properties of the substrate, the low polarity and high crystallinity of the nylon plus glass fiber substrate make it difficult to oil the paint, so it needs to be adhesion enhancement treatment on its surface.

3.The construction process specification problem, the paint should be baked until it is dry after spraying, and it is easy to fall off when the adhesion test is carried out without drying.

Solution to poor adhesion of nylon plus glass fiber substrate oil spray:

The method of enhancing the adhesion between nylon plus glass fiber substrate and paint is traditionally corona, flame, grinding and other treatment methods, which can not be effectively guaranteed in construction and stability, operability, safety, etc., and the primer nylon plus glass fiber treatment agent can fit the spraying production line, directly priming and then spraying paint, improving adhesion by enhancing wetting performance, improving intermolecular force, chemical bonding and mechanical occlusion after dissolving swelling. Solve the problem of nylon and glass fiber material spray paint and silver ridges.

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.

The surface of nylon can be sprayed with UV, PU, rubber oil, UV vacuum plating, color paint, anti-alcohol paint, etc., and the adhesion is generally not good.

The main solution to improve the adhesion environment of nylon or glass fiber nylon surface is to spray the nylon fiber treatment agent on the substrate after cleaning and cleaning by the wide vertical celery through priming, and the cleaning must be done at this time, because oil stains will form a weak interface layer. Then spray the topcoat or primer directly, promote the adhesion of each other through the middle layer of the nylon surface treatment agent, change the fiber branch good substrate, enhance the chemical bonding with the paint, and form a solid coating of the paint.

The first step is to analyze the footage.

1.How much glass fiber is added to the nylon material, and the glass fiber is added to make the material stronger, but it also increases the difficulty of the coating to adhere to the material.

2.Confirm whether it is nylon plus 30% or nylon plus 50% glass fiber, etc., and confirm that the material is good to deal with the problem of not oiling.

Solution. Nylon plus glass fiber is sprayed with a single component or a double component of paint per mu, to achieve the adhesion effect, you can use a layer of nylon treatment agent, the oil injection stability is good, and there will be no adhesion.

The principle of nylon treatment agent.

Jingchu nylon treatment agent can effectively disrupt the arrangement of surface molecular clusters, increase their dyne value, and effectively 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. Whether it is adding 30 glass fiber or 55 glass fiber, it has the effect of changing the functional group, and judging the crack can solve the problem in a targeted manner.
