The invention further provides a preparation method for the heat-resisting and acid-base-resisting polyurethane plate. The polyurethane plate prepared through the preparation method has excellent heat-resisting and acid-base-resisting performance.

Description

technical field [0001] The invention relates to the field of polyurethane materials, in particular to a heat-resistant, acid- and alkali-resistant polyurethane board and a preparation method thereof. Background technique [0002] Polyurethane refers to a large class of polymers containing more carbamate groups on the main chain of the molecule. It is a polymer material between plastics and rubber. It has a large elongation and a range of hardness. Wide, large formula adjustment range, excellent wear resistance and mechanical properties. The cast polyurethane elastomer is the most important of the three major processing types of polyurethane elastomers. Its consumption accounts for 60% of the PUR amount. It has diversified chemical structures, easy adjustment of viscosity, excellent processing technology, and is easy to put into industrial production. , easy to use and fast curing, so it is very suitable for making large and complex components. The polyurethane wear-resista...
