Abstract

This invention discloses an environmentally friendly elastomeric polyisoprene paint, which comprises: elastomeric polyisoprene emulsion 45-73 wt.%, deionized water 8-12 wt.%, thickener 0.2-0.8 wt.%, dispersant 0.4-0.7 wt.%, antifoamer 0.2-0.3 wt.%, antifreezer 1.5-2.5 wt.%, film-forming agent 1.6-2.8 wt.%, preservative 0.5-1.5 wt.%, pigment 12.4-25.3 wt.%, and filler 22-34 wt.%. The paint has such advantages as good waterproof property, good crack resistance, good contamination resistance, good weathering resistance, high strength, high safety, no toxicity and wide applications. The paint can be applied on architectures, vehicles, ships, coiled materials and wood materials.

Description

technical field [0001] The invention relates to the preparation of a polyisoprene high elastic emulsion and a coating product, in particular to a high elastic emulsion coating. Background technique [0002] Elastic coatings represent an aspect of the most advanced coating technology in the world at present. Its successful research and development provide a technical guarantee for promoting the application of high-performance coatings in construction, automobiles, coils and other fields in my country. In today's world, the emulsions used in the leading elastic emulsion coatings are mainly the following three types: [0003] a) Polyacrylate-organic silicon graft copolymerization emulsion [0004] b) Polyurethane-acrylate mixed dispersion [0005] c) UV cross-linked acrylic elastic emulsion [0006] US Patent US2004 / 0034146A1 discloses a peelable elastic coating for automobile surfaces developed by Bayer AG of Germany. The good elasticity of this temporary protective coatin...
