Fast-melting environmental protection high anti-pollution hot-melt marking paint and preparation method thereof

Abstract

The invention provides a quick-melting environment-friendly high anti-fouling hot melt marked line coating and a preparation method thereof. The quick-melting environment-friendly high anti-fouling hot melt marked line coating consists of the following raw materials in parts by weight: 115-135 parts of petroleum resin, 8-10 parts of a modified plasticizer, 8-12 parts of wax, 15-35 parts of pigment, 0-350 parts of glass bead, 550-850 parts of filler, 1-1.5 parts of water, 0.2-1.5 parts of an antioxidant and 3-7 parts of thermoplastic plastic. Water in components forms an emulsified azeotrope with oily substances during the production process, so that the compatibility among the components is increased, and the adding amount of petroleum resin can be reduced; during construction, along withthe increment in temperature, the emulsified azeotrope can prolong the retention time of the water at the high temperature stage, so that the melting speed of the coating is accelerated; the evaporation of the water can take away part of heat, so that the coating is hard to coke, the water can be completely evaporated finally, and the oily substances newly return to the components, therefore, theperformance of the coating cannot be affected. Through adding the thermoplastic plastic, while the compressive strength and the friction resistance of the coating are improved, the high temperature resistance of the coating is enhanced, and further the anti-fouling ability of the coating is further improved.

Description

【Technical field】 [0001] The invention relates to the technical field of road coatings, in particular to a fast-melting environmental-friendly high-fouling-resistant hot-melt marking paint and a preparation method thereof. 【Background technique】 [0002] In recent years, with the rapid development of the transportation field, road markings have been widely used in all levels of highways and airport environments, and are an important part of traffic travel and traffic safety. Road traffic markings have to withstand harsh environments such as wind, sun, rain, high temperature, high humidity, low temperature, etc., the wheels are crushed and worn, and even in winter in the north, they often face the tearing of snow chains, deicing agents, etc. erosion etc. Therefore, due to the particularity of the application environment of traffic markings, the particularity of preparing road marking materials itself is determined. [0003] The raw material components of the existing markin...

Problems solved by technology

[0003] The raw material components of the existing marking paint usually include lipophilic substances such as resins, waxes, plasticizers, and hydrophilic substances such as fillers, so the compatibility of the paint when heated and melted is poor, so that the paint is The heating and melting process takes a long time, the stirring resistance is large, and the local high temperature causes the coating to coke and carbonize, and then the final marking line has technical problems such as poor wear resistance, not bright color, and short service life.

Furthermore, in order to meet the various indicators of the national standard for marking paint, the proportion of organic matter in the raw material components of the existing marking paint is relatively high, which wastes resources and increases environmental pollution.
