Problems solved by technology

[0003] Polyurethane materials are made of polyisocyanates, polyols and other stabilizers as raw materials, and are prepared by catalytic reactions of catalysts at a certain temperature. A type of catalyst commonly used in the synthesis of polyurethane materials is metal organic compounds. This type of organometallic catalyst was first Organic compounds of lead and mercury, but because lead and mercury are heavy metals, they are harmful to the human body and cause serious environmental pollution, they have been listed as prohibited products, and the existing ca
