Description
Technical field
The present invention relates to rubber-plastic foamed material for sole of shoe of a kind of light resilient on-slip and preparation method thereof, it is right that the material is applied to
Light weight, damping, on-slip and comfortableness require higher medium-to-high grade sole.
Background technology
With the development and the raising of living standards of the people of social economy, people are more concerned with the comfortableness and safety of footwear
Property, such as the performance requirement such as damping, on-slip and lightweight to footwear is improved constantly.Also occur in that in the market many more popular
Functional element such as " light ", " saturating ", " soft ", " bullet " etc., and among these " light " mainly by reducing the proportion of material for sole of shoe
Realize, at the same time will also ensure the performance of material, i.e., with will also require certain damping performance while certain elastic force.
The main purpose of damping is to reduce the impulsive force suffered by foot.In the market the shock-absorbing function of article of footwear mainly by structure and
Material is realizing.The structural damping of sport footwear, after Nike " ZOOM ", each company also releases new construction footwear, such as New one after another
" ENCAP ", " REV " of Balance companies, and the shock-absorbing sole such as 361 ° of " magnetic suspension " comes out one after another, and tries hard to from science angle
Degree expands the New function that footwear protect pin.The material damping of sport footwear, mainly at the middle bottom or interior bottom of footwear with damping and amortization
The material of energy, such as ethylene-vinyl acetate copolymer（EVA）Expanded material, polyurethane foam material and silica gel material.An international line
Branding campaign footwear generally use ethylene-vinyl acetate copolymer（EVA）Material, is characterized in light weight, and elasticity is good；High density
Polyurethane（PU）PU is exactly made special circle by the middle bottom interlayer that material is slapped after being also commonly used in, " shox " basketball shoes of Nike
Cylindrical unit, bottom in slapping after being placed in.We have found that shock-absorbing sole material in the market still suffers from some shortcomings by investigation,
If EVA foamed shoe soles are due to crosslinking agent（Adopt mostly DCP）Problem sole can be made to remain some penetrating odors, while which stops
Sliding and buckling poor-performing, wrestling of easily skidding particularly on wet and smooth road surface；Polyurethanes foaming sole material is resistance to
Hydrolytic stability is poor, and service life is shorter；Although gum expanded material is with good physical property and snugness of fit, by
In self structure reason, the shortcomings of it is larger to there is shrinkage factor, poor dimensional stability, and proportion is still higher after foaming, although can be with
Proportion is reduced by increasing foaming agents content, but the hardness of material also can decline therewith, cause sole not reach hardness requirement.
Present invention is generally directed to the deficiency of shock reducing non slipping material for sole of shoe in the market, it is proposed that a kind of light resilient on-slip
Rubber-plastic foamed material for sole of shoe.The matrix that the material is adopted is for brombutyl（BIIR）, ethylene-vinyl acetate copolymer
（EVA）And low density polyethylene (LDPE)（LDPE）.BIIR has good damping, ageing-resistant, air-tightness, high temperature resistant and resistance to chemical attack
Etc. performance, while which is also with the caking property good with other matrixes；EVA has light specific gravity, and molding rate is fast, dimensional stability
Preferably the features such as；LDPE has well processed rheological property, it is possible to increase the dimensional stability after rubber pange, while improving
The processing characteristics of rubber.The present invention adopts azodicarbonamide (AC) for foaming agent, prepares lightweight by moulded from foam technique and subtracts
The rubber-plastic foamed material for sole of shoe of shake on-slip, the material have advantages below：(1) good damping shock absorption function；(2) good on-slip
With pressure change performance；(3) low-shrinkage, high-dimensional stability；(4) good snugness of fit.
The content of the invention
The present invention is intended to provide rubber-plastic foamed material for sole of shoe of a kind of light resilient on-slip and preparation method thereof.On realizing
Goal of the invention is stated, the present invention provides technical scheme below：A kind of rubber-plastic foamed material for sole of shoe of light resilient on-slip, its feature exist
In, its quality component and it is：
