Description

technical field [0001] The invention relates to the technical field of polyurethane, in particular to a nano silicon dioxide 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 extremely flammable, and there are great fire safety hazards in the application process. They are also easy to hydrolyze and have poor water resistance. In addition, their heat resistance and strength are not very ideal, which greatly limits the use...
