Abstract

The invention relates to the field of adhesives, particularly a high-temperature-boiling-resistant adhesive and a preparation method thereof. The adhesive comprises a component A, a component B and a curing agent. The component A is composed of the following components in parts by mass: 6 parts of lauric acid, 25 parts of benzene dicarboxylic acid, 10.25 parts of glycerol, 12.5 parts of ethylene glycol, 4.75 parts of trimethylolpropane and the balance of ethyl acetate. The component B is composed of the following components in parts by mass: 36.5 parts of refined castor oil, 39.5 parts of mixed dibasic acid polyester, 11.5 parts of toluene diisocyanate and the balance of ethyl acetate. The curing agent is composed of the following components in parts by mass: 15.5 parts of toluene diisocyanate, 58.5 parts of trimethylolpropane and the balance of ethyl acetate. The high-temperature-boiling-resistant adhesive has the advantages of wide application range, favorable performance, high adhesive strength, no cracking under high-temperature boiling conditions, acid / alkali resistance, oil resistance, no metallic ions and no toxicity, and conforms to the requirements of food sanitation. The technical process is simple, does not generate harmful products in the reaction process, and is beneficial to environmental protection.

Description

technical field [0001] The invention relates to an adhesive, in particular to an adhesive resistant to high-temperature cooking. Background technique [0002] Adhesive refers to a kind of natural or synthetic, organic or inorganic substances that can connect two or more parts or materials together through the adhesion and cohesion of the interface, collectively referred to as glue. Adhesives, also known as adhesives, are customarily referred to as glue. [0003] In short, an adhesive is a substance that can bind adherends together through bonding; in order to pursue the use effect of traditional adhesives, the formula ratio is unreasonable and wastes raw materials. Contents of the invention [0004] In view of the defects in the prior art, the purpose of the present invention is to provide a composite glue suitable for polyester film, dacron film, vacuum aluminized film, polypropylene, polyethylene and them. [0005] The technical solution adopted in the present inventio...
