Abstract

The present invention discloses a high peel strength adhesive for shoes, wherein the raw materials comprise, by weight, 90-105 parts of modified polyurethane, 25-28 parts of carboxy styrene-butadiene rubber, 20-23 parts of water-soluble chlorosulfonated polyethylene, 30-35 parts of a water-soluble epoxy resin, 5-10 parts of a calcium zinc stabilizer, 3-8 parts of an anti-aging agent, and 50-80 parts of water, and during the modified polyurethane preparation method, graphene oxide is subjected to acidification and ultrasound treatment, the obtained material is grafted with cyclohexanedimethylene diisocyanate to obtain modified diisocyanate, and the modified diisocyanate, an anionic hydrophilic chain extender and other materials are combined to generate the modified polyurethane. According to the present invention, the high peel strength adhesive for shoes has characteristics of excellent peel resistance, high toughness and good bonding property, and adopts water as the solvent, such that the environmental protection is good, and the high peel strength adhesive can not harm the health.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to an adhesive for shoes with high peeling strength. Background technique [0002] my country is the largest producer, consumer and exporter of footwear products in the world, with an annual output of several billion pairs of shoes, accounting for more than 50% of the total global shoe production. China consumes more than 2 billion pairs of shoes every year, surpassing the United States and ranking first in the world. There are more than 20,000 shoe-making enterprises in China, of which more than 80% of the shoes produced are adhesive shoes, and the consumption of shoe glue is more than 200,000 tons. The use of adhesives has greatly improved the production efficiency of the shoe industry. [0003] The development of shoe adhesives often uses organic solvents. Organic solvents are chemically inactive in the natural environment and are not easy to be decomposed, causing huge pollu...
