Materials for making shoe soles and processing method

Abstract

The invention discloses a novel sole material and a processing method for manufacturing the sole material. The main raw materials of the raw material formula are poly vinyl acetate and linear low density polyethylene, wherein, the main function of POE polyene elastomer or SBS thermoplastic rubber is to render soles elastic and malleable; the main function of a foaming agent is to act on the foaming performance of the soles so that the soles have softness; the main function of a cross-linking agent is the generation of effects of lubrication, softness and no sticky mold. During processes of material mixing, performing plastication and the extrusion granulation, various process conditions can be well handled so that the physical and chemical properties of materials can be well embodied. The soles manufactured with the material formula and the manufacturing method has the advantages of high strength, good tenacity, enough flexibility, being free-crack, good stability and comfortable wearing.

Description

technical field [0001] The invention relates to a shoe sole material, in particular to a formula of a shoe sole material and a processing method of the shoe sole material. Background technique [0002] At present, the main materials used for shoe soles are rubber, thermoplastic elastomers and plastics. The advantages and disadvantages of shoe soles made of various materials are different. For example, shoe soles made of rubber have excellent durable friction performance and elastic reset. Good and other advantages, but its processing process needs to be vulcanized, resulting in harmful substances, and its waste and foreign matter cannot be recycled, and the use of thermoplastic elastomers as materials has the advantages of convenient processing, simple process, and waste products can be recycled, but its wear resistance is average. , many manufacturers have improved the material formula, but because they do not have a better raw material formula and have not solved the solub...

[0002] At present, the main materials used for shoe soles are rubber, thermoplastic elastomers and plastics. The advantages and disadvantages of shoe soles made of various materials are different. For example, shoe soles made of rubber have excellent durable friction performance and elastic reset. Good and other advantages, but its processing process needs to be vulcanized, resulting in harmful substances, and its waste and foreign matter cannot be recycled, and the use of thermoplastic elastomers as materials has the advantages of convenient processing, simple process, and waste products can be recycled, but its wear resistance is average. , many manufacturers have improved the material formula, but because they do not have a better raw material formula and have not solved the solubility, crystallization state, coupling crosslinking, etc. between the formula raw materials and have not mastered toughening, strengthening, The time, temperature, proportion and process conditions of additives such as anti-slip are accurately grasped, etc., resulting in quite a few soles with poor toughness and strength, poor dimensional stability, poor elastic recovery, and some soles are deformed. water seepage
