Cold-coating quick-drying type colored pavement antiskid coating

Abstract

A cold-coating quick-drying type colored pavement antiskid coating is composed of resin, a filler, a pigment, an antiskid aggregate, a curing agent, an auxiliary agent and the like, wherein the antiskid coating comprises 23%-30% of the resin, 35%-42% of the filler, 5%-7% of the pigment, 30%-40% of the antiskid aggregate, 0.7%-1.5% of the curing agent, and 0.2%-0.4% of the auxiliary agent, wherein the resin is active acrylic resin; the filler is a calcium carbonate powder; the pigment is iron oxide red or medium chrome yellow; the antiskid aggregate is ceramic particles or calcined bauxite; the curing agent is dibenzoyl peroxide; and the auxiliary agent is composed of 60%-75% of a leveling agent and 25%-40% of an anti-settling agent. The cold-coating quick-drying type colored pavement antiskid coating has the beneficial effects that the antiskid coating has the remarkable advantages of better performance, green environment protection, good durability and convenient construction.

Description

technical field [0001] The present invention relates to a kind of anti-slip coating for colored pavement. The anti-slip coating is laid on the road surface to improve the anti-skid ability of the road surface. Be alert and improve traffic safety. Background technique [0002] Pavement anti-slip coating is different from ordinary floor coatings and colored asphalt pavements. It is a coating used for anti-slip markings and anti-slip pavements on various roads. In recent years, road surface anti-slip coatings have been more widely used. On the ETC non-stop toll lanes at the highway toll gates entering and leaving Beijing, eye-catching and non-slip colored anti-slip road surfaces are paved to ensure the safe and orderly passing of cars. mouth. Some pedestrian overpasses are also paved with colored non-slip pavement, which effectively prevents pedestrians from falling due to wet and slippery bridge decks. In 2015, Beijing completed the "Hundred Kilometer Road Slow Traffic Syst...

AI Technical Summary

Problems solved by technology

[0005] (1) The marking equipment is complicated, the construction efficiency is low and the safety is poor

At present, most of the construction of hot-melt coatings in the world is to use a hot-melt kettle to melt the coating at high temperature, and then transfer it to a hand-push marking car for manual scraping and marking. The labor intensity is high, the construction efficiency is low, and the high-temperature operation is dangerous. consume fuel, pollute the environment

In addition, there must be supporting construction equipment, such as car-mounted hot-melt kettles, primer sprayers, old line removal machines, etc. There are many types of full-set marking equipment and the cost is expensive.

[0006] (2) The construction technology is complex and difficult to master

Since the hot-melt paint must first be melted at high temperature and then scrape the marking line, if the technology is not skilled, it will easily cause the denaturation of the paint

Such as: causing the marking line to peel off, poor durability, discoloration, cracking, blistering, etc., which will affect the service life of the marking line

[0007] (3) Hot-melt paint markings have good adhesion on asphalt pavement, but poor adhesion on cement pavement

The main reason is that the hot-melt coating is a thermoplastic material, which expands with heat and contracts with cold, and has poor temperature variability. The coating contains a large amount of
