A hot-melt high wear-resistant and anti-pollution yellow traffic marking material and its preparation method

Abstract

The invention discloses a heat melting high-wear-resistant anti-pollution yellow traffic marking material and a preparation method thereof. The preparation method is used for preparing the traffic marking material in the technical field of traffics. The heat melting high-wear-resistant anti-pollution yellow traffic marking material comprises the following components: petroleum resin, modified rosin resin, di-n-butyl phthalate, glass beads, an ethylene vinyl acetate copolymer, microcrystalline wax, refined white mineral oil, quartz sand, quartz powder and cadmium yellow. The traffic marking material prepared by using the preparation method not only can be used for improving the wear resistance and anti-pollution capacity of a traffic marking, but also can be used for increasing the adhesive force of the traffic marking.

Description

technical field [0001] The invention relates to the technical field of traffic, in particular to a hot-melt high wear-resistant and anti-pollution yellow traffic marking material and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of transportation technology, various road markings have been widely used in various grades of highways and airports, and have played an increasingly convenient role in people's daily life and transportation. After the road markings are painted on the traffic roads, they not only have to go through wind, sun and rain, but also have to go through the oil stains on the road surface, the rolling and wear of the wheels, and even in the winter in the north, they often have to face anti-skid chains. tearing, erosion of deicing agents, etc. Therefore, the particularity of the application environment of traffic markings determines the particularity of the materials used to prepare road markings.

AI Technical Summary

Problems solved by technology

[0003] At present, commercialized hot-melt road marking paints basically use low-grade road traffic marking materials mixed with hot-melt polymer adhesives such as petroleum resin and modified rosin resin and stone powder. The use of high-end traffic roads cannot meet the needs of highways, airports and other environments with strict road marking requirements.

It is mainly manifested in the following aspects: First, the hot-melt road traffic marking material is very easy to cause pollution due to its unscientific material ratio. The surface is sticky, which causes the dirt on the vehicle tires to stick to the surface of the marking line through the rolling of the wheels, making the surface of the marking line appear gray-black, affecting the visual effect of the marking line, and greatly increasing the hidden danger of traffic accidents ;Secondly, due to the poor adhesion of the marking material in winter, when encountering low temperature weather, the surface of the coating becomes brittle and prone to large-scale peeling off; at the same time, due to the poor wear resistance of the marking line, it has not reached the corresponding friction coefficient, when ice and snow cover the road marking surface to a certain thickness, the marking surface will become smoother than the road surface, which is more likely to cause traffic accidents
