Description
Technical field
The present invention relates to the sports shoes technical field, the EVA foam material of using at the bottom of especially a kind of sports shoes, and preparation method thereof.
Background technology
Along with the continuous growth of chemical materials output and the continuous expansion of purposes, chemical materials brings people simultaneously easily, the also pollution that has brought a large amount of solid waste to form to environment, world's public hazards have been become, sole etc. as depleted plastic garbage bag, junk, there is the degraded difficulty, the technical barrier that is difficult to decompose.And because the comfortableness of sports shoes is extensively promoted, people have also caused bigger pollution to environment when accepting sports shoes convenient comfortable.
The material that is adopted at the bottom of the sports shoes is generally and has soft elastomeric plastic material at present, as ethylene-vinyl acetate copolymer (EVA) commonly used, there is the shortcoming of degradation property difference in the stable performance of EVA own, and this plastic material is a chemical materials simultaneously, is unfavorable for environmental protection; Therefore advocate environmental protection at present, under the situation of low-carbon (LC) life, need be optimized adjustment the material at the bottom of the sports shoes.
Summary of the invention
The present invention is directed to deficiency, propose the EVA material used at the bottom of a kind of sports shoes, kept existing soft snappiness, reduced the use of industrial chemicals, improved the degradation property of this material simultaneously, reduced pollution environment.
In order to realize the foregoing invention purpose, the invention provides following technical scheme: the EVA material of using at the bottom of a kind of sports shoes is made of the component of following weight part:

Cellmic C 121 1.0～5.0.
Preferably, described treated starch multipolymer is polymerized by 10wt%～50wt% starch, 1wt%～3wt% vinylformic acid and 50wt%～90wt% ethylene-vinyl acetate copolymer.
Preferably, described starch is green starch, tapioca (flour), sweet potato starch, sweet potato starch, yam starch, wheat kind of starch, water caltrop starch, Rhizoma Nelumbinis starch or W-Gum.
Preferably, described weighting agent is kaolin, talcum powder, diatomite, graphite, carbon black, silicon-dioxide, aluminum oxide powder, glass powder, asbestos powder, mica powder, silica powder, carbon fiber.
Compared with prior art, the present invention proposes main EVA foam material by starch/ethylene-vinyl acetate copolymer/ethene-a-olefin copolymer blending and modifying, starch is applied in the chemical plastic, reduced the consumption of industrial chemicals, solve the in short supply of oil industrial chain, and starch is the nature green food, can promote the development of rural economy; Simultaneously because but the starch based derivative possesses the characteristic of natural degradation, finally be decomposed into carbonic acid gas and water, can not pollute, improve the readily degradable energy of EVA foam material of the present invention, and advocate the industry epoch of sports shoes " low carbon emission reduction, environmental protection " environment.
EVA foam material of the present invention adopts ethylene-vinyl acetate copolymer, process mixed and modified with ethene-a-olefin copolymer, treated starch multipolymer, make the foam material abscess careful even, have superior water-retaining capacity and wet putting, can promote the printing efficiency of foamed products.
Add weighting agent, can promote environmental protection EVA foam material uniform in foaming degree, smoothness, glossiness, can also reduce cost; Add dicumyl peroxide and Cellmic C 121, utilize the chemical foaming method, cause crosslinked with dicumyl peroxide, Cellmic C 121 as whipping agent according to its principle Quality Control system foaming formulation and condition, make the expansion ratio that needs, hardness, the foaming quality of closed air hole structure makes its secondary frothing forming process better uniformly.And zinc white is as catalyzer, can reduce the decomposition temperature of foaming effectively, helps Cellmic C 121 AC whipping agent to improve catalytic efficiency; Zinic stearas can promote the activity of zinc white, and the effect of lubricant is also arranged, and promotes the quality of product, improves the stripping result of foamed products.
Weighting agent commonly used has kaolin, talcum powder, diatomite, graphite, carbon black, silicon-dioxide, aluminum oxide powder, glass powder, asbestos powder, mica powder, silica powder, carbon fiber etc.The present invention preferably adopts talcum powder.
Starch commonly used has beans starch, tapioca (flour), sweet potato starch, sweet potato starch, yam starch, wheat kind of starch, water caltrop starch, Rhizoma Nelumbinis starch, W-Gum etc.What the present invention preferably adopted is the modified copolymer of W-Gum.
The present invention also provides above-mentioned EVA preparation methods, may further comprise the steps:
1., take by weighing each component in following weight part ratio:
