Abstract

The invention relates to a coating for road safety facilities, in particular to the coating for a road safety guardrail. The road guardrail coating with width marking and warning function is characterized by consisting of a coating and micro glass beads, wherein the coating is prepared from raw materials including a high molecular polymer resin, a long-afterglow light emitting material, a filler, a pigment, an auxiliary agent and a solvent; and the road guardrail coating comprises 10 to 40 weight percent of high molecular polymer resin, 2 to 30 weight percent of long-afterglow light emitting material, 5 to 50 weight percent of filler, 0 to 5 weight percent of pigment, 0.1 to 5 weight percent of auxiliary agent, 10 to 40 weight percent of solvent and 1 to 30 weight percent of micro glass beads. The road guardrail coating has a rust-proof and corrosion resistant effect on the guardrail and has the effect of marking the width and warning for a road at night.

Description

technical field [0001] The invention relates to a coating for road safety facilities, in particular to a coating for road safety guardrails. Background technique [0002] Road guardrail is an important facility for maintaining highways and ensuring safety, and it plays a role in preventing cars from rolling over and rushing out of the road. Hot-dip galvanizing is now commonly used for protection. Different protection systems should be selected for different atmospheric environments: in rural areas and areas with less serious pollution, a separate hot-dip galvanized layer protection or a separate powder spraying protective guardrail is used; in heavy industrial areas or coastal areas, especially in areas with acid rain In areas, a double-coat protection system of hot-dip galvanized layer and paint should be adopted. The double-coat protection system is to coat the surface of the hot-dip galvanized layer to form a protective layer, which is usually called a double-coat syste...
