| titleOfInvention | Polyurethane elastic material and polyurethane elastic parts using the same |
| abstract | The present application relates to a polyurethane elastic material and a polyurethane elastic part using the same; the polyurethane elastic material is prepared by the following methods: (1) weigh the polymer polyol and diisocyanate and carry out vacuum dehydration respectively; (2) under nitrogen protection The dehydrated diisocyanate is added dropwise to the dehydrated polymer polyol, and then a catalyst is added; the prepolymerization reaction is performed by heating to obtain a prepolymer; (3) the styrene-butadiene-styrene block copolymer and the Silicone rubber, mixed with prepolymer after vacuum dehydration; (4) Weigh small molecular diol and phthalate, add dropwise to prepolymer after vacuum dehydration and stir; then inject into mold and vulcanize after molding get the finished product. Polyurethane elastic parts, including end plates, intermediate reinforcement plates and polyurethane blocks. The polyurethane elastic material prepared in the present application has good elasticity, its elongation at break is over 730%, and its rebound rate is over 43%. |
