Abstract
The invention provides an adhesive for environment-friendly regeneration sponge. The adhesive for environment-friendly regeneration sponge consists of the following components: 5-70% of polyether or polyester polyol, 5-70% of isocyanate, 5-20% of plasticizer, 0-5% of chain extender and 0.5-2% of catalyst. Organic solvent and toluene diisocyanate are not added in the adhesive for the environment-friendly regeneration sponge, so that the damage caused by high volatility of the organic solvent and the toluene diisocyanate is avoided. The adhesive for environment-friendly regeneration sponge is pollution-free and harmless to the human body, and is high in processing property with the adoption of the plasticizer.
