Description
Technical field
The utility model relates to the production field for preparing of footwear material, more specifically a kind of secondary MD of overlay film shaping
Sole.
Background technology
As Beijing is successfully bid for 2008 Olympics, increasing Chinese start to be keen to the various sports of what,
High performance sport footwear also just turns into commodity in short supply.As the forth generation material for sole of shoe after rubber, PVC, SBS Hou, TPU (heat
Plastic polyurethane elastomer) there is more excellent elasticity, wearability, tear resistance and bendability, it is high special of various requirement
One of sole preferred material with footwear such as football boot, ice skates, climbing boot etc..
Material currently used for athletic shoe sole production mainly has PVC, PU, EVA and TPU, and TPU therein is dashed forward by what performance
Go out and there is environmentally friendly concept, start to show up prominently.PVC's is cheap, but be hardened when temperature is low it is easy to break split, when temperature is high again
Easily soften, and there is medical research to prove that PVC can discharge harmful dioxin, the large-scale sporting goods manufacturer of advanced country
Such as NIKE is progressively with the material substitution such as TPU PVC；PU material weights are light, heat-resist, abrasion resistance is good, long lifespan, price
It is relatively low, but the cost of investment of special project is high (machine, mould and raw material), and finished product is difficult to recycle again；EVA pliability,
Elastic good, chemicals-resistant and tinctorial property are excellent, and technology is relatively ripe, and EVA expanded materials are widely applied very much
In footwear material field, but EVA wearabilities are poor, and easily by scratching or abrasion, and its waterproof and moisture permeability is poor, influences shoes
Quality and the life-span.And TPU has the advantages that strong wearability, tensile strength and elongation at break height, against weather are good, although
It is more extensive in hardness, weight and Shortcomings, but in general in price, TPU application market.
The applicant in 03 month 2016 No. 29 have submitted it is a on " overlay film puffed rice polyurethane footwear material and its production work
The utility application of skill "（Application No.：201610185476.6）, the program in original PU basic units by covering
One layer of TPU protects counterdie, sole is had high moisture-inhibiting, good hand touch, water-fastness to wait the various outstanding physics spies that TPU has
Property, the production application of PU soles has been expanded, while TPU puffed rice expanded beads are set by mixing in PU basic units, the two molecule
Characteristic is approached, and splendid inter-molecular binding force can be obtained in foaming process, makes TPU protection bottom membranes and PU basic units ideally
Fopam gluing.But as the midsole shoe material of medium-to-high grade shoes, typically using EVA expanded materials, EVA foaming bodies are not only
With the excellent physical features such as pliability, elasticity is good, and its chemicals-resistant and tinctorial property are excellent, are medium-to-high grade soles
Splendid midsole selection, and TPU material layers are not close to both EVA foam material layers molecular characterization, it is impossible to are obtained very
Combine well, prevent sole from possessing the excellent specific property of TPU materials and EVA material simultaneously, so, those skilled in the art is anxious
A kind of new process for producing is worked out, is combined together both footwear materials, is applied jointly on same a pair of sole,
The sole is possessed desirable physical and the chemical characteristic that both respectively have, improve the quality and class of shoes.
Utility model content
The utility model discloses a kind of secondary MD soles of overlay film shaping, and its main purpose is to overcome prior art
Above shortcomings and shortcoming, there is provided a kind of new sole and the technique for producing the sole, it can not only make TPU materials
Protection film layer ideally apply in the secondary MD midsoles of EVA foaming body materials by overlay film, the sole is not only had excellent
Flexility and good elastic performance, and there is the fine qualities such as the smooth of TPU materials, waterproof, moisture-inhibiting, fashion simultaneously,
Sole product is greatly enriched, improves the class and quality of sole, and extends the service life of sole.
