A kind of road marking paint coating and preparation method thereof

Abstract

A road marking paint coating and a preparation method thereof. The modified water-based acrylic resin is used as the main film-forming material. It is good, and increases the cross-linking point of the coating, so that the coating forms an interpenetrating network cross-linking structure, which overcomes the poor weather resistance and wear resistance of traditional road marking paint coatings, insufficient cross-linking degree, mechanical properties and adhesion of the coating. Low defects; and, using polyamine curing agent as a bridge, the fluorinated graphene filler is well combined with the main film-forming material, so that it is not simply mechanically blended but chemically bonded together, significantly increasing The crosslinking density of the coating extends the service life of the coating. The road marking paint prepared by the preparation method of the invention can effectively improve the performance index and service life of the road marking paint and reduce the production cost.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a road marking paint coating and a preparation method thereof. Background technique [0002] At present, with the rapid improvement of people's living standards, cars have greatly improved people's quality of life as a necessary living tool. However, due to the increase of vehicles, road traffic problems are becoming more and more prominent, so wear-resistant, weather-resistant and durable road marking paint is very important. [0003] In 1917, the first generation of solvent-based road marking paint came out, but its service life was short and its VOC content was high; in 1950, the second generation of hot-melt road marking paint came out. Compared with the first generation, its service life was greatly improved. But the disadvantage is that it requires high temperature construction and relatively high energy consumption; in 1990, the United States began to develop a new gener...

AI Technical Summary

Problems solved by technology

[0003] In 1917, the first generation of solvent-based road marking paint came out, but its service life was short and its VOC content was high; in 1950, the second generation of hot-melt road marking paint came out. Compared with the first generation, its service life was greatly improved. But the disadvantage is that it requires high temperature construction and relatively high energy consumption; in 1990, the United States began to develop a new generation of high-grade acrylic weather-resistant road marking paint. The developed new high-grade road marking paint products have the advantages of durability and good reflective effect, but Compared with other products, there are problems such as high construction cost and difficult construction

[0004] At present, most areas in my country still use the most primitive solvent-based road marking paint and the second-generation hot-melt road marking paint. Only some first-tier cities began to test the use of imported new high-end road marking paint from the year before last. , but its expensive price limits the general application
