Classification of road marking coatings for hot melt marking coatings

At present, there are three kinds of road marking coatings used in China:

Solvent-based coatings at room temperature.

Room temperature solvent-based coatings have the longest history as road marking coatings, and they are also the most widely used in research and application in China. 90%-95% of the mileage of road markings painted in China is still covered by room temperature paint. The advantage of solvent-based road marking coating at room temperature is that it can be used for operation and construction under normal temperature conditions, and the construction is simple and convenient, easy, adaptable, low and low-cost, and has the advantages of low one-time investment.

The main applications of room temperature solvent-based road marking coatings in China are: oxidation and solid pressing ester coatings, cross-linked curing epoxy resin coatings and acrylic road marking coatings. Oxidation and solid pressure ester adhesive coating is a kind of road marking coating applied in China in the sixties and seventies, although it is quite cheap but the performance is very poor, has been no longer used.

The performance of cross-linked curing epoxy resin coating as a road marking coating is significantly better than that of ester adhesive coating, but the drying time of this coating is very long, and the use of two-component is inconvenient, which limits its use.

The road markings of hot-melt marking coatings can be divided into three categories, namely ordinary hot-melt marking coatings, reflective hot-melt marking materials, and protruding (also called ** type) hot-melt marking coatings. If the ordinary hot-melt marking coating does not contain reflective glass beads, the reflective glass beads will not be removed on the surface during construction; Reflective hot-melt standard coatings shall contain 18% to 25% reflective glass beads in accordance with relevant national standards, and reflective glass beads shall be dispensed on its surface during construction; Protruding hot-melt marking line also needs to add 18% to 25% reflective glass beads according to the national standard, and at the same time remove the reflective glass beads on the surface during construction, and add reflective glass beads according to the national standard The road marking has a good reflective effect. What is a hot melt marking coating?

What are the main ingredients of hot melt marking coatings?

Road marking paint is divided into:

1. Hot-melt marking coating.

2. Normal temperature marking coating.

3. Two-component marking coating.

Hot melt marking coatings are divided into:

1. Ordinary type.

2. Vibration type.

3. Color anti-slip type.

Hot melt marking coatings are composed of resins, calcium carbonate, pigments, fillers, PE waxes, EVAs and glass beads. --Hot-melt marking paint outlet.

Answer] :d This question mainly examines the buried type of hot-melt paint for traffic markings. The main function of traffic markings is to convey rules, warnings and guidance on road traffic.

It is composed of various lines, arrows, words, patterns, façade markings, solid markings, protruding road signs, etc., which are drawn or installed on the road. The coating used for painting pavement marking is divided into solvent-based, hot-melt, two-component, water-based four, if the pavement marking has reflective requirements, it should also be mixed in the paint or sprinkled with glass beads during construction. Protruding road signs are divided into two categories: A and B according to whether they have retroreflective properties

The one with retroreflective performance is a Class A protrusion road sign; It does not disturb the retroreflective performance of the class B protrusion road sign.

Both hot melt marking coatings and asphalt can be used in the construction of road markings, but they differ in their base materials and construction methods.

Hot-melt marking coating is made of resin, rubber and other materials as the main components, adding pigments, fillers, additives and other additives after melting and mixing evenly, directly painted on the road surface, through heating and compaction to make it adhere to the road surface, forming a clear, durable road marking. The hot-melt standard accompaniment line coating is simple to install, the material composition is controllable, and the quality of the marking line is stable, so it is widely used in highways, urban trunk roads and other road sections.

Asphalt is mainly a natural asphalt mineral hail or industrial product obtained by petroleum processing, asphalt becomes viscous when the temperature rises, and can be painted on the road surface to form road markings. Asphalt is less weather-resistant, susceptible to ultraviolet light, and the construction process is more complex.

In summary, although both hot-melt marking coatings and asphalt can be used for the construction of road markings, hot-melt marking coatings have certain advantages in terms of controllable material composition and stable marking quality, and are widely used in modern road construction.

Hello, the formulation ratio of hot melt marking coatings depends on different application scenarios and requirements. The following are a common formulation ratio: Main ingredients:

Acrylic resin: 45% - Acrylate monomer: 20% - Filler (e.g. calcium carbonate):

30%- Photophoretic agent (such as stearate): 2%- New inorganic light stabilizer: 3% Among them, cracked acrylic resin is the main basic component of hot-melt marking coatings, which can provide excellent durability and scratch resistance; Acrylate monomer is a crosslinker of acrylic resin, which can enhance the abrasion and chemical resistance of coatings; Fillers can increase the hardness, stability and cost of coatings; Photophoretic agents can improve the reflective properties of coatings; The new inorganic light stabilizer can improve the weather resistance of the coating and prolong the service life of the coating.

Please note that the specific formulation ratios and ingredients can be adjusted according to actual needs and regulations and standards in different regions. It is recommended that when selecting and using hot-melt marking coatings, relevant safety specifications and operating procedures should be followed to ensure the use effect and safety of the lift.

Heated solvent-based pavement marking coating is an improvement on the traditional normal temperature solvent-based pavement anti-disturbance training marking coating, and the purpose of improving hail bending is to increase the solid content so that a thicker coating film can be formed. The solid content of the coating film of the heating solvent-based pavement marking coating is as high as more than 85%, and the construction temperature is between 50 and 80, because the viscosity of the coating becomes smaller, easy to spray and the drying time becomes shorter, therefore, the thickness of the dry film can be reached. Due to the complex and expensive construction equipment required by the heating solvent-based pavement marking coating, it has not been widely used in China, and is used more in Europe and the United States.

The formulation of hot melt marking coatings includes concentrated pigment fillers, solid additives, and plasticizers.

Additive. The formula ratio of each manufacturer is about the same, but there is a difference in specificity, and the detailed formula ratio determines the quality and cost of hot melt coatings, so it is necessary to ask specific manufacturers for a detailed understanding.

The formula of hot-melt marking coating road sign is mixed with several pigments, a small amount of fillers and solid additives, stirring for 5 minutes, adding resin, plasticizers, liquid additives, stirring for 5 minutes, and then adding other fillers for 5 minutes, discharging packaging, the formula of the coating is generally adjusted according to the temperature, pavement properties and raw material specifications. The molecular composition of the film-forming substance of the hot-melt marking coating directly affects the mechanical properties of the coating, as well as the weather resistance and wear resistance of the coating.

The formula of nanocomposite hot-melt marking coating is basically composed of film-forming substances, pigments, fillers, special reinforcing materials, glass beads, and other additives, and is characterized by special reinforcing materials containing nano-scale fibers, nano-scale whiskers, micron-level fibers, and micron-level whiskers. The preparation process is as follows: firstly, the film-forming substance is poured into the mixing kettle, and then the additives are added, and after stirring evenly, pigments, fillers, glass beads, and special reinforcing materials are added in turn under stirring conditions, and after stirring evenly, the kettle can be bagged.

It has excellent anti-abrasion and anti-cracking capabilities, and has the advantages of fast heating and melting, rapid drying, anti-discoloration, anti-chalking, water resistance and alkali resistance.

The composition of hot melt marking paint is as follows:

1) Synthetic resin, a derivative of petroleum, hot melt coating is the use of the thermoplasticity characteristics of synthetic resin, so that the coating has fast drying, the use of hot melt paint hot melt type to make the marking coating and the road surface can be well bonded.

2) Coloring pigments, the general hot melt paints are yellow and white, so coloring pigments are a necessity for hot melt coatings.

3) Glass beads, adding glass beads to the paint can improve the recognizability of the night marking, and the glass beads can be refracted and reflected, and the light can be focused.

4) Additives, additives are an important element of stain resistance and plasticity of hot melt marking coatings.

Land Rover Transport's hot melt coatings are of good quality and reasonable.

The hot-melt road marking coating uses the plasticity of synthetic resin to make the hot-melt coating quick-drying, and the hot-melt type of synthetic resin is used to make the marking road surface stick firmly. Hot-melt reflective road marking coatings are generally composed of thermoplastic resins, pigments and fillers, plasticizers, reflective glass beads and other additives.

Two-component road marking paint is made by mixing two components in a certain ratio, applied to the road surface and chemically reacting to form a film. Two-component road marking coating increases the film-forming rate of the coating film, improves the flexibility and strength, whether it is cement road or asphalt road has good adhesion, long service life, is not easy to crack at low temperature, and will not crack at high temperature. Generally, the composition of two-component road marking coatings is generally composed of epoxy resin, polyurethane, acrylic acid, etc.
