Description

technical field [0001] The invention relates to the technical field of polyurethane, in particular to a carbon nanotube modified 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, ordinary polyurethane materials are easily hydrolyzed, not resistant to water, have poor surface properties, low strength, and unsatisfactory heat resistance, which greatly limits the practical application of polyurethane materials. Contents of the invention [0003] Based on the techni...
