Abstract

The invention relates to a thermoplastic polyurethane elastomer material, which is prepared from the raw materials in parts by weight: 100 to 120 parts of toluene diisocynate, 90 to 100 parts of polyester polyol, 0.2 to 0.5 part of dibutyltin dilaurate, 0.4 to 0.6 part of triethanolamine, 1 to 3 parts of trimethylolpropane, 15 to 20 parts of glass fiber, 5 to 10 parts of silvering glass fiber, 5 to 15 parts of porous ceramic packing, and 0.1 to 0.3 part of silane coupling agent, wherein the ratio of the glass fiber to the silvering glass fiber is 2 to 3.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and more specifically, the invention relates to a modified thermoplastic polyurethane elastomer material. Background technique [0002] Polyurethane is the abbreviation of polyurethane, which is a new kind of high molecular organic material, which is a kind of macromolecular compound synthesized by the polyaddition reaction of isocyanate group and hydroxyl compound. In 1937, Professor Otto Bayer of Germany first synthesized polyurethane by addition polymerization of isocyanate groups and polyol compounds, marking the beginning of the polyurethane industry. In the next 80 years, the polyurethane industry has been greatly developed. Polyurethane elastomers are widely used due to their excellent properties such as wear resistance, mechanical properties, resilience, weather resistance, oil resistance, and oxidation resistance. Every aspect of our daily life is constantly affecting and chan...
