Abstract

The invention discloses a heat-resistant and acid-alkali-resistant modified polyurethane adhesive for shoes. The heat-resistant and acid-alkali-resistant modified polyurethane adhesive for the shoes is prepared from the following raw materials: bisphenol A diglycidyl ether epoxy resin, buna-N rubber, thermoplastic styrene-butadiene rubber, coumarone resin, terpene resin, phenolic resin, polypropylene amide, polyimide, bismaleimide, polybenzimidazole, nanocrystalline metal tin powder, multiwalled carbon nanotubes, aluminium nitride, nano-montmorillonite, sericite powder, ultrafine silicon dioxide, aluminium dihydrogen phosphate, zinc oxide, zirconium oxide, ferric oxide, a silane coupling agent KH-560, ethyl acetate, acetone, naphthenic oil, stearic acid, sulphur, an accelerant TMTM, a curing agent and an anti-aging agent. The adhesive for the shoes, prepared by the invention, has excellent heat-resistant and acid-alkali-resistant properties.

Description

technical field [0001] The invention relates to an adhesive, in particular to a heat-resistant acid and alkali-resistant modified polyurethane adhesive for shoes. 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 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 heat and acid and alkali resistance of the existing adhesives used in the field of shoemaking cannot meet the actual needs, so it is urgent to design a heat-resistant, acid-...
