Abstract

The invention relates to a special high-temperature-resistant adhesive for leather, which is prepared from the following raw materials in parts by weight: 15-28 parts of methyl cellulose, 8-12 parts of phenolic resin, 2-4 parts of acetone, 20-36 parts of polyurethane prepolymer prepared by reaction between isophorone diisocyanate and polyadipic acid-1,4-butanediol ester diol, 3-6 parts of carbon tetrachloride, 4-5 parts of acrylic acid, 5-7 parts of acacia gum, 4-10 parts of dibutyl acetate, 11-21 parts of chloroprene rubber, 5-7 parts of pine camphor oil, 8-14 parts of vinyl acetate, 3-7 parts of nano zinc oxide and 4-6 parts of anti-aging agent. The special high-temperature-resistant adhesive for leather has the advantages of excellent high temperature resistance, higher water resistance, higher flexibility, high binding force and low tendency to shedding.

Description

technical field [0001] The invention relates to a special adhesive for high temperature resistant leather. Background technique [0002] With the improvement of people's living standards, people's demand for high-quality goods also increases, because leather products are soft, tough, not easy to deform when exposed to water, not easy to shrink when dry, durable to humidity and heat, chemical resistance, etc., especially breathable And anti-aging performance is very prominent, so the sales volume is increasing day by day, and the requirements for its production process are becoming more and more strict. For example, in the processing of leather products, the requirements for adhesives are also getting higher and higher. Adhesives are an important process in the bonding of leather, especially in the leather shoe industry. Leather adhesives are a class of reagents used in leather for bonding leather to articles, and leather to leather. Bonding is just a physical change. Howev...
