Problems solved by technology

However, the flame-retardant polyurethane currently sold in the market in my country has the defects of high cost and unsatisfactory flame-retardant effect. In addition, the thermal stability of polyurethane itself is poor, and its mechanical properties basically disappear in the environment of 80-90 ° C, and the temperature of 200 ° C Thermal degradation occurs immediately on the surface, thus limiting the application of polyurethane coatings

Abstract

The invention discloses a high performance modified polyurethane coating. The coating comprises isophorone diisocyanate, polytetramethylene ether glycol, alkynyl group-containing polyol, phenylboronic acid, trimethylol propane, N,N-dimethylbenzylamine, cerium hydroxide, acidified carbon nanotubes, organic modified montmorillonite, 2,3-dibromo tripropylborate, triethylamine, 3,3'-diamino-4,4'-dihydroxydiphenylsulphone, 1-sulfolane-3-ethoxycarbonyl-5-hydroxypyrazole, 1,4-bis(dimethylhydroxysily)benzene, a leveling agent, methylsilicone oil, a wetting agent, benzoic acid, propylene glycol, dihydroxyacetone, adipic dihydrazide, liquid styrene butadiene rubber, liquid nitrile butadiene rubber and water. The high performance modified polyurethane coating has the advantages of excellent flame retardation performance, high strength, good heat stability, strong adhesion to a substrate, and long service life.

Description

technical field [0001] The invention relates to the technical field of polyurethane coatings, in particular to a high-performance modified polyurethane coating. Background technique [0002] Polyurethane has good wear resistance, water resistance, solvent resistance and excellent mechanical properties. At present, it has been widely used in elastomers, foam plastics, coatings, adhesives and biomedical materials. Polyurethane coatings are usually used in leather finishing, textile printing and dyeing, papermaking, architectural coatings, adhesives, cast steel coatings and other fields. In these fields, almost all flammable materials are involved. If these materials are used without flame retardant Disposal will inevitably become a fire hazard. The flame retardancy of polyurethane coatings is one of the important directions of polyurethane functionalization. However, the flame-retardant polyurethane currently sold in the market in my country has the defects of high cost and ...
