Problems solved by technology

This type of plasticizer has a small molecular weight, and it is easy to migrate outward to the surface of the marking line during the use of the marking line, which will affect the performance of the marking line
[0004] However, most of the current hot-melt marking coatings have the following disadvantages: (1) shrinkage and distortion will occur when the curing is fast, the surface leveling property is poor, and the bonding ability to glass beads is poor; when the curing is slow, the glass beads sink inside the marking line , the ability to reflect light is reduced
(2) The paint film is easy to fade under long-term ultraviolet radiation
(3) Wear resistance is not good enough

Abstract

The invention provides a high-standard hot-melt marking paint and its preparation method and application. The high-standard hot-melt marking paint includes the following raw materials in parts by weight: 6-10 parts of solid epoxy resin, C 5 / C 9 4-8 parts of copolymerized petroleum resin, 2-6 parts of isocyanate modified alkyd resin, 0.5-1.2 parts of nano-silica / zirconia composite material, 12-22 parts of glass microspheres, 25-35 parts of filler, titanium White powder 10-16 parts, pigment 3-6 parts, epoxy soybean oil 2-4 parts, silane coupling agent 0.3-0.6 parts, anti-settling agent 0.5-1.3 parts. The hot-melt marking paint prepared by the present invention has high standards and excellent comprehensive performance, so that the obtained coating film has strong adhesion, good adhesion, weather resistance, wear resistance, and good UV resistance. It has a good application prospect.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a high-standard hot-melt marking coating and its preparation method and application. Background technique [0002] For the beautification of roads, the regulation of vehicle driving and the more rational use of roads, road markings have become static information instructions and regulatory language, and highly iconic road markings depend on high-performance marking paint. With the rapidity of modern construction, environmental protection and high requirements for wear resistance, weather resistance and durability of markings, low-cost hot-melt marking paints have become the first choice for road marking paints in my country. [0003] The main film-forming substances of hot-melt marking paint are thermoplastic resins, including petroleum resins, rosin resins, modified rosin resins, epoxy resins, etc., which are self-drying and film-forming by heating, melting and cooling. Its ma...
