Problems solved by technology

At present, most soft materials such as domestic leather use neoprene, grafted neoprene rubber or natural rubber as adhesives, and most of these adhesives use benzene-based toxic solvents, which are harmful to the health of producers and users. Both bring serious harm, improve technology, overcome deficiencies to meet market demand

Abstract

The invention relates to a special adhesive for leather. The special adhesive is prepared from the following raw materials in parts by weight: 8-14 parts of sodium hydroxide, 4-7 parts of ethyl acetate, 8-17 parts of stearic acid, 4-10 parts of waste rubber nanopowder, 2-3 parts of emulsified silicone oil, 6-11 parts of carboxyl butadiene-styrene rubber, 4-8 parts of zinc oxide, 7-9 parts of triethylene diamine, 4-6 parts of n-hexane, 12-18 parts of lauryl mercaptan, 9-15 parts of methyl methacrylate, 12-24 parts of chloroprene rubber and 6-8 parts of silicon dioxide. The special adhesive for the leather, which is disclosed by the invention, has the beneficial effects of good heat stability, high adhesive strength, good film-forming property and no environment pollution.

Description

technical field [0001] The invention relates to a special adhesive for leather. Background technique [0002] Leather products are products processed from fur and leather as the main raw materials, including boots, shoes, gloves, clothing and hats, luggage, stationery, etc. Because leather products are soft and tough, not easy to deform when exposed to water, not easy to shrink when dry, durable to humidity and heat, chemical resistance and other properties, especially the air permeability and anti-aging properties are very prominent. Therefore, with the improvement of people's living standards, people's demand for high-quality goods also increases. Adhesives play a very important role in leather product processing. Leather bonding is an important process, especially as In the leather footwear industry. 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. At present, most so...
