Abstract

The invention relates to waterborne polyurethane for automotive trim and automotive chassis paint. The waterborne polyurethane is prepared from 10-30 parts of fat-soluble particles, 10-50 parts of polyisocyanate, 20-40 parts of a hydrogen-containing compound, 0.5-2 parts of a flame retardant, 1-5 parts of a chain extender, 1-5 parts of zeolite powder, 0.5-0.8 part of an epoxy resin curing agent, 0.2-0.6 part of an organic drier, 10-50 parts of a water-based curing agent, and 0.5-1 part of a cell regulator. The waterborne polyurethane prepared by the method has the advantages of moderate viscosity, light color, high brightness and good leveling property, is non-toxic after being cured with epoxy resin, has better insulativity, water resistance and wear resistance, and can play a good protective role when being used for automotive trim or automotive chassis paint.

Description

technical field [0001] The invention relates to the field of automobile interior spraying or automobile chassis paint spraying, in particular to a water-based polyurethane used for automobile interior decoration and automobile chassis paint. Background technique [0002] The scientific name of automobile chassis armor is automobile chassis anti-collision, anti-rust and sound insulation (primer), that is, chassis paint, a high-tech adhesive rubber asphalt coating, which is non-toxic, high coverage, and high adhesion. Spray on exposed parts such as vehicle chassis, wheel hubs, fuel tanks, car underpanels, and trunks. Water-based polyurethane is a new type of polyurethane system that uses water instead of organic solvents as the dispersion medium. It is also called water-dispersed polyurethane, water-based polyurethane or water-based polyurethane. Water-based polyurethane uses water as a solvent, and has the advantages of no pollution, safety and reliability, excellent mechanic...
