Abstract

The invention discloses high-tensile-strength polyurethane and belongs to the technical field of resin preparation. The high-tensile-strength polyurethane is prepared from the following raw materials:polyurethane, polyester polyol, ethylene vinyl acetate, polycarbonate diol, polyester polyol, carboxyl-terminated polybutadiene, polyphenylene sulfide, methacrylic acid, low density polyethylene, chlorinated paraffin, pine tar, nano ceramic powder, nano boron nitride, zinc borate, aluminum tripolyphosphate, nano aluminum oxide, calcium sulfate whisker, nano attapulgite, silicon micro-powder, talcum powder, triple superphosphate, nano calcium carbonate, pearlite, microlite, glass fiber, a silane coupling agent KH-560 and a high-tensile-strength enhanced modification auxiliary agent; the high-tensile-strength polyurethane is prepared through the steps of preparing a base material, preparing a modified material, mixing materials including the base material, the modified material and the like. The high-tensile-strength polyurethane prepared by the invention has excellent tensile strength.

Description

technical field [0001] The invention relates to the technical field of polyurethane preparation technology, in particular to a polyurethane with high tensile strength and a preparation method thereof. Background technique [0002] Polyurethane is a polymer containing a carbamate group in the main chain of a macromolecule called polyurethane. Polyurethane is divided into two categories: polyester polyurethane and polyether polyurethane. Polyurethane has many excellent properties, so it has a wide range of uses. [0003] Chinese patent application document "A Polyurethane Material and Its Preparation Method (Application Publication No.: CN106751734A)" discloses a polyurethane material and its preparation method. The polyurethane material is mainly prepared from organosilicon-modified polyurethane prepolymer as a raw material. , low content of free isocyanic acid, green and environmental protection, high mechanical strength, good product stability, no foaming after constructio...
