Special adhesive for safe leather

Abstract

The invention relates to a special adhesive for safe leather, which is prepared from the following raw materials in parts by weight: 25-37 parts of neoprene, 12-24 parts of perchloro-ethylene resin, 6-12 parts of 2,2-dimethylolpropionic acid, 8-14 parts of neopentyl glycol, 7-13 parts of sodium silicate, 5-6 parts of potassium persulfate, 2-4 parts of methyl cellulose, 3-6 parts of borax, 3-7 parts of stabilizer, 5-8 parts of aluminum hydroxide, 12-27 parts of lysine diisocyanate, 2-4 parts of mildew preventive, 12-24 parts of ethyl acetate and 15-28 parts of water. The special adhesive for safe leather has the advantages of high bonding strength, chemical resistance, biological attack resistance, no toxic components, no irritating smell, high safety and no harm to the human body.

Description

technical field [0001] The invention relates to a special adhesive for safe leather. Background technique [0002] Leather adhesive is a kind of reagent used in leather for bonding leather to articles, leather to leather, and this bonding is only a physical change. Adhesives play a very important role in the processing of leather products. Leather bonding is an important process, but traditional adhesives use neoprene, grafted neoprene or natural rubber as adhesives. Most of these adhesives use benzene-based toxic solvents, which have a pungent smell and pose a great safety hazard. They will not only affect the environment, but also bring serious harm to the health of producers and users. , now urgently need to study a kind of adhesive with high safety, to improve the defect of the adhesive security problem on the market at present. Contents of the invention [0003] In view of the deficiencies in the prior art, the problem to be solved by the present invention is to pro...
