The flame-retardant heat-resistant polyurethane adhesive comprises the following raw materials in parts by weight: 45-70 parts of poly(1,4-butylene adipate), 10-35 parts of poly(1,5-glutaryl carbonate)diol, 8-15 parts of biferrocenyl alcohol, 50-70 parts of isophorone diisocyanate, 2-10 parts of sucrose, 3-15 parts of a chain extender, 3-12 parts of 1-aminoethylidene-1,1-diphosphonic acid, 1-8 parts of calcium alginate fiber, 2-8 parts of walnut shell powder, 1-5 parts of polyimide, 1-5 parts of amino silicone oil, 2-5 parts of epoxy resin, 2-10 parts of aldehyde ketone resin, 3-9 parts of attapulgite, 3-15 parts of nano alumina, 2-10 parts of 1,2-dimethylol carborane, 30-80 parts of a solvent, and 0.1-0.8 part of an antioxidant. The flame-retardant heat-resistant polyurethane adhesive provided by the invention has excellent heat resistance and flame retardancy, high curing speed and high adhesive strength with a substrate.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a flame-retardant and heat-resistant polyurethane adhesive. Background technique [0002] Adhesive refers to a natural or synthetic, organic or inorganic substance that can connect two or more parts or materials together through the adhesion and cohesion of the interface. It can be divided into epoxy resin adhesives, polyurethane adhesives, polyvinyl acetate adhesives, etc. [0003] Polyurethane adhesives refer to adhesives containing carbamate groups or isocyanate groups in the molecular chain, and its molecules contain isocyanate and carbamate groups with strong polarity and high chemical activity. Porous materials such as wood, leather, fabric, paper, ceramics, and materials with smooth surfaces such as metal, glass, rubber, plastics, etc. all have excellent chemical adhesion, and have good toughness, adjustability, and low temperature resistance. Has been widely used in f...
