Problems solved by technology

[0002] Adhesives are an important component in the road paving process, but the existing adhesives mainly use solvent-based adhesives, which cause serious environmental pollution and contain a large amount of toxic and harmful substances, which have a greater impact on the outside world
At the same time, when solvent-based adhesives are used in paving roads, due to the short application period of the adhesive’s reaction operation, it is easy to appear that the bonding with other components is not fastened. Fast; after the road paving is completed, the curing time of this type of adhesive is longer, which prolongs the time for the paved construction road to be released to the outside world

Abstract

The invention discloses a solvent-free type colorized anti-skid road surface adhesive. The solvent-free type colorized anti-skid road surface adhesive comprises, by weight, 68 parts to 74 parts of polyether type amines cross-linked sizing, 25 parts to 30 parts of polyisocyanate and 1 part to 2 parts of catalysts, wherein the catalysts comprise, by weight, 0.5 part to 1 part of zinc 2-ethylhexanoate and 0.5 part to 1 part of 2-ethylhexoic acid, and the polyisocyanate is diphenyl-methane-diisocyanate. Colorized ceramic particles formed by the solvent-free type colorized anti-skid road surface adhesive have the advantages that the colorized ceramic particles are environmentally friendly, the service life is long, the curing time is short, and release of construction roads is accelerated.
