Among them, the characteristics of chloroprene adhesive are: large initial adhesion, high bonding strength, good durability, flexible adhesive layer, good elasticity, impact and vibration resistance, good oil resistance, water resistance, alkali resistance, acid resistance, and solvent resistance. Performance, good adhesion to a variety of materials, easy to use, low price, but its heat resistance is poor, water resistance is not good, and storage stability is poor
In order to overcome the shortcomings of traditional neoprene adhesives such as poor heat resistance, poor water resistance, poor storage stability, and high toxicity, a high-performance adhesive for shoemaking is produced by improving the formula.

Abstract
The invention discloses a high-performance adhesive for shoemaking. The high-performance adhesive is prepared from the raw materials in parts by weight: 100-120 parts of styrene, 100-150 parts of ethyl acetate, 20-25 parts of neoprene CR121, 15-20 parts of dimethylbenzene, 1-2 parts of 4,4'-diphenylmethane diisocyanate, 8-12 parts of polyisobutylene, 2-3 parts of 3-aminopropyl trimethoxysilane, 2-3 parts of polytetrahydrofuran ether glycol, 3-5 parts of SG-2 PVC (Polyvinyl Chloride) resin, 1-2 parts of ferrocene, 8-10 parts of epichlorohydrin rubber H45, 5-8 parts of epoxy resin modified polyamide hot-melt adhesive and the like. The adhesive disclosed by the invention has excellent heat resistance and water resistance, is high in adhesive strength, good in storage stability, good in environmental protection performance, good in use effect and convenient to use and is water-resistant and dampproof.
Description
Technical field [0001] The invention relates to an adhesive, in particular to a high-performance adhesive for shoemaking. Background technique [0002] With the development of the shoe industry, adhesives for shoes have also developed correspondingly, and there are many varieties, but the largest amount of them is neoprene adhesive and polyurethane adhesive. Among them, the characteristics of neoprene adhesive are: large initial adhesion, high bonding strength, good durability, flexible adhesive layer, good elasticity, impact and vibration resistance, good oil resistance, water resistance, alkali resistance, acid resistance, and solvent resistance Performance, good adhesion to a variety of materials, easy to use, low price, but its heat resistance is poor, water resistance is poor, and storage stability is poor. In order to overcome the disadvantages of traditional neoprene adhesives such as poor heat resistance, poor water resistance, poor storage stability, and high toxicity, ...
