Production formula of polyurethane foaming product based on polyether raw material

Abstract

The invention discloses a production formula of a polyurethane foaming product based on a polyether raw material. A high-elasticity polyether raw material and a resin raw material are subjected to a switch polymerization reaction under the action of alkylene oxide; a polyurethane foaming product with certain elasticity is generated; a polyurethane foaming product added with a chemical additive isoverlapped with a polyurethane foaming raw material added with a physical additive; the basic metal in the chemical additive is matched with the catalyst to remarkably improve the tensile property ofthe product; after the physical additive is added, the wear resistance and the corrosion resistance of the product are ensured; a reinforcing material is additionally arranged between the physical additive layer and the chemical additive layer, so that the connection tightness of the physical additive layer and the chemical additive layer is further improved, the produced polyurethane foaming product has good tensile property while having good wear resistance and corrosion resistance, and the application field is wider.

Description

technical field [0001] The invention relates to the technical field of polymers, in particular to a production formula of polyurethane foam products based on polyether raw materials. Background technique [0002] Polyurethane foam products are products made of polyurethane foam. Polyurethane foam is made of isocyanate and polyether as the main raw materials. Under the action of various additives such as foaming agent, catalyst and flame retardant, it is mixed through special equipment. High-molecular polymers foamed by high-pressure spraying on-site are often used as thermal insulation and waterproof materials in the construction field due to their low thermal conductivity. In order to ensure the wear resistance and corrosion resistance of materials, the existing polyurethane foam products are usually The hardness of the product is set very high, and the elastic coefficient is low. During long-term outdoor use, it is easy to cause cracks due to thermal expansion and contract...
