Description

technical field

[0001] The invention belongs to the field of macromolecular materials, and relates to a preparation method of a polyurethane elastomer, in particular to a layered silicate modified organosilicon grafted polyether type polyurethane elastomer, a preparation method and an application thereof. Background technique

[0002] The main chain of polyurethane elastomer contains repeated urethane groups (-NHCOO-), which has good wear resistance, high strength, elasticity, oil resistance, solvent resistance, radiation resistance, electrical insulation, and a wide range of applications. Used in mining, metallurgy, transportation, mold lining, machinery parts, etc. However, the application of this material is greatly limited because of its low temperature resistance, large internal heat generation, flammability, poor water resistance and poor dielectric properties.

[0003] The silicone structure contains Si-O bonds, and its bond energy is as high as 422.2kJ / mol. Siloxane...
