Hot-melt-type marking coating and preparation method thereof

Abstract

The invention provides a hot-melt-type marking coating. The coating is prepared from, by weight, 80-120 parts of thermoplastic resin, 20-40 parts of a bone material, 5-15 parts of pigments, 3-10 partsof a reflective material, 0.02-0.05 part of a whitening agent, 0.01-0.03 part of a defoaming agent, 2-6 parts of a novel mercaptan curing agent, 1-2 parts of an anti-settling agent, 1-4 parts of Twain and 0.03-0.06 part of a graphene-oxide-modified benzophenone UV anti-ultraviolet agent. The hot-melt-type marking coating prepared by means of the method has the advantages of being short in film forming and curing time and drying time, good in stain resistance, great in dustproof property, excellent in reflection effect, uniform in viscosity and good in anti-shedding performance after long-termstorage, safe, environmentally friendly, long in service life and the like, and has a broad application prospect.

Description

technical field [0001] The invention relates to the technical field of polymer coatings, in particular to a hot-melt marking paint. Background technique [0002] Road marking paint is a kind of safety mark and a "special voice". Usually, people use road marking paint to delineate vehicle driving lanes and channelize traffic, so as to strengthen traffic safety management, reduce vehicle and personal accidents and beautify urban roads. the goal of. Therefore, the performance requirements for road marking paint are relatively high, and usually require quick drying, visibility, anti-rutting, low-temperature and high-temperature resistance, wear resistance, rain reflective properties, etc., and with the continuous increase in the number of vehicles In order to prolong the service life of the marking paint and prolong the replacement cycle, it is usually required that the marking paint has good antifouling performance, and even needs to be able to absorb automobile exhaust to a c...

Problems solved by technology

In order to make the marking paint meet the requirements of use, a lot of innovative research has been carried out on the raw material formula and preparation method of the hot-melt type, hoping to enhance toughness, wear resistance, visibility, anti-fouling, anti-aging and other properties , so that the marking paint can overcome the defects of brittleness and cracking in winter, soft deformation in summer, poor anti-rutting performance, poor reflective visual effect at night and under rainwater immersion, etc.

For example, Chinese patent CN2005100476095 discloses a nanocomposite hot-melt marking paint, which improves the wear resistance and resistance of the marking paint by adding nano-scale fibers, nano-scale whiskers, micron-scale fibers, micron-scale whiskers, etc. as reinforcing materials. Cracking ability, but the reason for the cracking of the marking paint layer is not only the high temperature resistance, low temperature resistance and anti-rutting performance of the paint layer itself, but also the reason that the road surface will be damaged under high temperature, low temperature or high pressure and humidity environment. Deformation occurs, because the deformation trend of the road surface is inconsistent with the marking paint, which will cause the marking paint to crack or even fall off
