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
The present invention relates to a kind of material for sole of shoe, relate in particular to a kind of working method of prescription and this material for sole of shoe of material for sole of shoe.
Background technology
At present, the main raw that is used for sole has rubber-like, thermoplastic elastomer class and plastics class, its relative merits of the sole that various types of materials is made have nothing in common with each other, as its durable attriting performance excellence of sole made from rubber-like, advantages such as elastic reset is good, but its course of processing needs through sulfuration, produce objectionable impurities, its useless foreign matter can't be recycled, and it is easy to process to adopt thermoplastic elastomer to be that material has, technology is simple, waste product is recyclable, but its wear resisting property is general, for this reason, there are many manufacturing enterprises that material prescription is improved, composition of raw materials reaches the solubleness that does not solve preferably between the formula material but because it does not have preferably, crystalline state, the crosslinked grade of coupling and do not grasp toughness reinforcing, strengthen, the anti-skidding release time of waiting auxiliary agent, throw in temperature, the accurate assurance of input ratio and processing condition etc., making has considerable sole toughness and intensity difference, poor dimensional stability, recovery of elasticity is not good, the sole that has also can produce distortion, and fracture infiltration phenomenon takes place.
Summary of the invention
Technical solution problem of the present invention provides a kind of new material for sole of shoe and the method for processing this material for sole of shoe thereof.
For addressing the above problem, the technical solution adopted in the present invention is, a kind of material for sole of shoe is made by the composition of raw materials of following ratio of weight and number:
