Problems solved by technology

It better solves the bonding of PVC and PU materials with high surface energy, but has the disadvantages of environmental protection, unstable quality, poor adhesion to complex materials, etc., and cannot be applied to the development requirements of the shoe industry.
In recent years, many production and scientific research units have also tried to make various modifications, but the above problems still have not been solved well

Embodiment 1

[0015] 320 parts of dimethyl carbonate, 176 parts of methylcyclohexane, 128 parts of butanone, 8 parts of methyl methacrylate MMA, 7 parts of neoprene A-90, 3 parts of acrylic acid, and 3 parts of chlorinated polyethylene. Put the above materials into the reaction kettle, dissolve at 60°C, stir at 90-120 rpm, heat up to 60°C, and then add BPO to 80°C to start the reaction. Control the temperature at 80-90°C, and then Add acrylic acid to a certain extent, after the reaction is over, add 2.4 parts of antioxidant 264, polymerization inhibitor, 20 parts of aliphatic carbonate, 2 parts of peroxide, 5 parts of accelerator thiazoles or guanidines, and 8 parts of auxiliary materials acid anhydride, active agent 6 parts of metal oxide and fatty acid, pressurized and vulcanized at 90-150°C for 15-100 minutes; after cooling, add 5 parts of phenolic resin, stir well and serve.

Embodiment 2

[0017] 320 parts of dimethyl carbonate, 176 parts of methylcyclohexane, 128 parts of butanone, 8 parts of methyl methacrylate MMA, 7 parts of neoprene A-90, 3 parts of acrylic acid, and 3 parts of chlorinated polyethylene. Put the above materials into the reaction kettle, dissolve at 60°C, stir at 90-120 rpm, heat up to 60°C and add the initiator BPO to start the reaction. Control the temperature at 80-90°C. After the reaction reaches a certain level, add acrylic acid, and then add 2.4 parts of antioxidant 264, polymerization inhibitor, 10 parts of aliphatic carbonate, 0.5 part of peroxide, 3 parts of accelerator thiazoles or guanidines, and 5 parts of anhydrides after the reaction is over. 4 parts of active agent metal oxide and fatty acid, pressurized and vulcanized at 90-150°C for 15-100 minutes; after cooling, add 5 parts of phenolic resin, stir well and serve.

Abstract

The invention discloses an aliphatic carbonate modified multivariant copolymerization grafted neoprene adhesive and a preparation method of the neoprene adhesive. The neoprene adhesive is characterized by comprising the following main raw materials in proportions: 40 to 50 parts of dimethyl carbonate, 20 to 30 parts of methyl cyclohexane, 15 to 20 parts of butanone, 8 to 10 parts of MMA (methl methacrylate), 7 to 10 parts of A-90, 2 to 5 parts of crylic acid, 2 to 5 parts of chlorinated polyethylene, 1 to 20 parts of aliphatic carbonate, 0.2 to 20 parts of peroxide, 0.2 to 20 parts of accelerant thiazoles or guanidines, 0.1 to 30 parts of auxiliary anhydride and 0.1 to 15 parts of active agents such as metallic oxide and fatty acid. The neoprene adhesive has better bonding intensity on the existing conventional PVC (polyvinyl chloride) and PU (polyurethane) isopolar materials, in addition, higher bonding intensity is also realized on ground surface energy materials TPR (thermal plastic rubber), EVA (ethylene vinyl acetate), PE (polyethylene) and the like, and obviously, the initial adhesion is greatly improved.

Description

technical field [0001] The invention relates to the technical field of grafted neoprene adhesives for shoes, in particular to an aliphatic carbonate modified multi-component copolymerized grafted neoprene adhesive. Background technique [0002] At present, the adhesives used in the production of leather shoes, sneakers, sneakers, and sports shoes are mostly neoprene and MMA binary graft copolymers, that is, the currently used grafted neoprene. It better solves the bonding of PVC and PU materials with high surface energy, but has the disadvantages of not being environmentally friendly, unstable quality, and poor adhesion to complex materials, so it cannot be applied to the development requirements of the shoe industry. In recent years, many production and scientific research units have also tried to make various modifications, but the above problems have not been well resolved. Contents of the invention [0003] The object of the present invention is to provide a kind of a...
