Abstract

The invention discloses a blade coating type two-component road marking coating and a preparation method thereof, and relates to the technical field of transportation coatings. The coating comprises acomponent A with the mass fraction of 57.45% and a component B with the mass fraction of 42.55%, and the component A is prepared from, by mass, 45%-55% of modified epoxy resin, 5%-10% of pigment, 35%-40% of filler, 0.5%-1% of auxiliaries and 0.2%-0.7% of thixotropic agents; the component B is prepared from the following components in percentage by mass: 30 to 40 percent of epoxy curing agent, 10to 15 percent of pigment, 50 to 55 percent of filler, 0.5 to 1 percent of auxiliary agent and 0.2 to 0.7 percent of thixotropic agent, wherein the component A and the component B are uniformly mixed for use according to the mass ratio of (1-1.5): 1. The blade coating type double-component epoxy marking coating has the advantages of strong adhesion to pavements and glass beads, good wear resistanceand water resistance, long service cycle, low maintenance cost, high solid content, no influence on the body health of constructors and high curing speed.

Description

Technical field: [0001] The invention relates to the technical field of transportation coatings, in particular to a scraping type two-component road marking coating and a preparation method thereof. Background technique: [0002] Road pavement markings play a vital role in regulating and guiding the safe and orderly circulation of pedestrians and vehicles, especially in unfavorable environments such as night and rainy days, so the continuous brightening of road markings and continuous excellent retroreflectivity are particularly important important. Hot-melt road marking materials have high solid content, fast drying, and convenient construction, and have been widely used. With the improvement of technology, the mechanical properties have also been greatly improved. However, due to the characteristics and defects of thermoplastic resin materials, hot-melt marking paint and The adhesion of glass beads is poor. Under the action of tire friction, the glass beads on the surface...
