| description | An elastomer material includes at least two components; the first component includes isocyanate prepolymer obtained through reaction of polyol and isocyanate, and its -NCO content is 22-30%; the second component includes 50-70 parts of polyether amine, 2-10 parts of liquid amine chain extender, 5-15 parts of hydroxyl-terminated polybutadiene, and 1-15 parts of hybrid hard segment material; the hybrid hard segment material includes one or more of nano titanium dioxide, nano aluminum oxide and nano silica. Through adjusting the -NCO content of the isocyanate prepolymer, increasing the hard segment content, and combining with the components in the second component, the invention ensures the elasticity of the polymer while improving its mechanical properties, and also improves the electrical insulation and wear resistance of the material. |
