Description

technical field [0001] The invention relates to the technical field of polyurethane, in particular to a high-strength polyurethane composite material. Background technique [0002] Polyurethane is a general term for macromolecular compounds containing repeated carbamate groups on the main chain. It has excellent properties such as wear resistance, oil resistance, tear resistance, and chemical corrosion resistance. It has a wide range of uses and can replace rubber, plastic, and nylon. etc., used in airports, hotels, building materials, automobile factories, coal mines, cement factories, high-end apartments, villas, landscaping, colored stone art, parks and other fields. However, the strength of ordinary polyurethane materials is not very high, and in the process of use, it is prone to defects such as yellowing, hardening, and rapid decrease in mechanical properties, which greatly limits the practical application of polyurethane materials. Contents of the invention [0003...
