Abstract

The invention discloses pavement skid-resistant coating with a photoluminescence function. The pavement skid-resistant coating comprises, by weight, 25-35% of resin, 25-45% of pigments and fillers, 20-40% of skid-resistant aggregate, 1-10% of photoluminescence nanometer materials, 0.5-2.5% of curing agents and 0.1-2.5% of auxiliaries. The sum of the mass percents of various raw materials for the pavement skid-resistant coating is 100%. The pavement skid-resistant coating has the advantages that energy can be acquired when external light sources irradiate on the pavement skid-resistant coating,the photoluminescence nanometer materials can be excited to emit light, good light emission effects can be realized by the pavement skid-resistant coating, and the pavement skid-resistant coating islong in service life; the identification degrees of pavement safety marks can be effectively upgraded under low-visibility and night conditions and the like by photoluminescence effects realized by the aid of the external light sources such as automobile lamps and street lamps, accordingly, the pavement traffic safety can be guaranteed, and the like.

Description

technical field [0001] The invention belongs to the technical field of paint compositions, in particular to a road surface anti-skid paint with photoluminescence function. Background technique [0002] Pavement anti-slip coating is a proportionate blend of polymer resin, aggregate, reflective micro-beads and stabilizers with different functions and then coated on the road surface, which plays the role of safety marking, anti-skid, and aesthetics, and is suitable for road surfaces in various environments. The currently used reflective micro-beads have poor binding force with the resin, and are easy to fall off, resulting in low reflective effect and short reflective life. The invention intends to replace the reflective microbeads with the photoluminescence material, and change from passive reflective light to active luminous light, thereby enhancing the marking effect of the anti-slip coating on the road surface and improving road safety.
