Advantages of hot melt marking coatings, the difference between hot melt marking coatings and asphal

The history of road coatings is similar to that of Japan, but the product development time is slightly earlier. The ratio of solvent-based paints and hot-melt paints at room temperature in the United States and Europe is roughly 6:4, and solvent-based coatings account for the main proportion.

Although the development history of foreign road coatings is not long, the development of road marking coatings and their application standards in developed countries in the world today is quite high. Road markings have a high coating rate on all grades of roads, and basically there must be lines on the road. In Japan, for example, 100% of highways are painted, 95% of national highways, and a certain percentage of country roads.

These sign lines are not only universal, but also complete and clear, bright and beautiful, and generally have a night reflective effect, which ensures the traffic safety of night driving. Three types of paints are used together, and most of them are hot-melt coatings, followed by heating coatings, and room temperature paints only account for a small proportion. The marking construction of the paint has formed a good industrial equipment.

Various types of coatings and various types of marking construction equipment are fully equipped, advanced and effective, and durable.

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 advantages of Land Rover Traffic Hot Melt Marking Coatings: short drying time, low cost, good adhesion, long life, good weather resistance and temperature difference resistance, bright colors, and good anti-fouling performance.

According to the different environments of the road, the requirements for marking are also different. They will not be greedy for cheap when choosing materials, and choose hot melt materials with high melt resistance, many outdoor areas need such materials, under normal circumstances, even if they often bask in the sun or rain in the place, it will not be easy to fade, and there is a certain period of use. Therefore, we can't be greedy for cheap, choose a good material, make the parking space marking more durable, and achieve the purpose of long-term use.

Good chromaticity: Selected raw materials, using imported coloring raw materials, bright and eye-catching marking, good reflection at night.

Fast drying: 3-5 minutes of coating, it can be dried, which is convenient for traffic construction.

Long life: Due to the strong adhesion of the product, film thickness, acid resistance, alkali resistance and no fading, the life of the marking line can be as long as three years.

Economical: Due to the long life of hot-melt parking space marking, ** mid-range, one-time construction, long-term benefits, more economical than ordinary marking.

Good construction performance: good fluidity, glass beads are not easy to sink, rich construction experience, good quality.

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.

Hello Hot melt marking coating is a common traffic marking material, and its brother let me know that the main components are resins, pigments, fillers, etc. In the process of use, due to its exposure to the air, after a period of time, the marking line will gradually lose its luster, discoloration slippery, damage and other phenomena, affecting its service life and visual effect. Therefore, we can extend the use time of hot melt marking paint by adding some special materials.

When changing the flow of hot melt marking coatings, this is usually done by increasing the resin content or using various processing aids. However, to a certain extent, this makes it difficult for the paint to dry and stabilize, and at the same time, it will cause the coating film to be soft and easy to stick to the stain. It is necessary to have a relatively suitable proportion of use to ensure the quality and make the coating have good fluidity.

It is necessary to achieve the purpose of controlling costs while being conducive to construction.

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.
