Problems solved by technology

[0003] When bonding TRP material soles, the traditional glue is not firmly bonded, easy to open, and has poor heat and water resistance. The curing time is long during bonding, which greatly increases the time spent on bonding, reduces efficiency, and cannot meet the needs of use. Demand, for this reason we have designed a kind of TPR material sole glue and its preparation method, to solve the above problems

Abstract

The invention discloses a glue for a TPR material sole. The glue is prepared from the following raw materials in parts by weight: 90-110 parts of ethylene-vinyl acetate interpolymer, 25-35 parts of butyl rubber, 20-30 parts of coumarone-indene resin, 5-8 parts of synthetic paraffin resin, 15-25 parts of talcum powder, 4-6 parts of calcium carbonate and 0.5-1.5 parts of 2,6-di-tert-butyl-p-cresol.The glue product provided by the invention has a high softening temperature and a low brittle temperature, can be used at most temperatures without losing viscosity, and has good adhesive bonding performance for various materials; and nitrile-butadiene rubber is added to improve the flexibility and elasticity of the glue solution, improve the adhesive bonding strength and shorten the curing time.

Description

technical field [0001] The invention relates to glue, in particular to a glue for TPR material shoe soles and a preparation method thereof. Background technique [0002] Glue is an intermediate that connects two materials. It mostly appears as a water agent. It belongs to the fine chemical industry and has a wide variety. It is mainly classified by adhesive, physical form, hardening method and adherend material. The common ones are instant glue, epoxy resin bonding, anaerobic glue, UV glue (ultraviolet light curing), hot melt adhesive, pressure sensitive adhesive, latex and so on. [0003] When bonding TRP material soles, the traditional glue is not firmly bonded, easy to open, and has poor heat and water resistance. The curing time is long during bonding, which greatly increases the time spent on bonding, reduces efficiency, and cannot meet the needs of use. Demand, for this reason we have designed a kind of TPR material sole glue and preparation method thereof, to solve t...
