Problems solved by technology

[0003] The invention with the patent No. CN02131651.7 discloses a water-based road marking reflective paint and its preparation method. However, it uses a titanate and silane composite coupling agent, and the cost is relatively high, and it only relies on titanium dioxide, heavy Calcium carbonate and light calcium carbonate are used as fillers. Practice shows that their wear resistance is not ideal and needs to be improved.

Abstract

The invention discloses a preparation method of a wear-resistant reflector marking coating for cement roads. The preparation method comprises the following steps: (1) weighing ingredients in percentage by weight; (2) putting sodium silicate into a reaction kettle, adding water to stir and dilute to relative density of 1.36-1.40, introducing steam in a jacket to heat, heating a liquid to 90 DEG C, with 5 DEG C plus or minus, slowly adding water-diluted sodium fluosilicate liquor under quick stirring, completing within 2 hours, then, adding zinc oxide, continuously reacting for 2 hours, and then cooling to 50 DEG C + / -5 DEG C; (3) adding water-soluble acrylic resin and silane while stirring, continuously reacting for 20-30 minutes, and then adding lauryl alcohol ester; (4) adding sodium hexametaphosphate and sodium polyacrylate while stirring, sequentially adding rutile titanium dioxide, talcum powder, attapulgite and ground calcium carbonate after uniformly mixing, and dispersing for 20-30 minutes; and (5) adding carboxymethylcellulose, ethylene glycol, glass beads and dimethyl silicone oil while stirring, and uniformly mixing to obtain a product.

Description

technical field [0001] The invention relates to the technical field of traffic facilities, in particular to a preparation method of road marking paint. Background technique [0002] At present, road marking coatings are divided into two types: solvent-based and hot-melt. Solvent type has a large amount of organic solvent volatilization during use, pollutes the environment, affects personal health, and has low strength, is not wear-resistant, and has a short service life. The hot-melt type has the characteristics of strong adhesion, quick drying, wear resistance, long life, and good day and night visibility, and has been widely used abroad. There are also achievements in China in recent years, as shown in the patent No. 88105009.1. However, due to the poor quality of domestic petroleum resin, titanium dioxide and other main raw materials, most of the production plants use imported raw materials, and the price is relatively high. Moreover, imported equipment is required, an...
