Description
Technical field
The present invention relates to technical field of polymer materials, be specifically related to the preparation technology of a kind of PU puffed rice sole.
Background technology
Along with successfully bidding for 2008 Olympics in Beijing, increasing Chinese start to make earnest efforts the various physical culture of what
Motion, high performance sport shoes the most just becomes commodity in short supply.As the rubber that continues, the 4th of the Hou of PVC, SBS the
For material for sole of shoe, TPU (Polyurethane Thermoplastic Elastomer) has more excellent elasticity, wearability, tear resistance
And bendability, it is that the sole of high the special purpose shoes such as football boot, ice skates, climbing boot etc. of various requirement is first-selected
One of material.
Be currently used for athletic shoe sole produce material mainly have PVC, PU, EVE and TPU, TPU therein by
What performance is prominent and has environmental protection concept, starts to show up prominently.PVC's is cheap, but the low time-varying of temperature
Hard easily jackknifing, easily deliquescing again during temperature height, and PVC can discharge two harmful evils to have medical research to prove
English, large-scale sporting goods manufacturer such as NIKE of advanced country etc. is the most progressively with material substitution PVC such as TPU；PU material
Expect lightweight, heat-resist, abrasion resistance is good, life-span length, price are relatively low, but the cost of investment of special project
High (machine, mould and raw material), finished product is difficult to again recycle；The pliability of EVE, elasticity are good, resistance to
Chemicals and tinctorial property are excellent, but production technology is relative complex, and use is enclosed and is confined to medium-to-high grade sport shoes
Enclose in.And TPU has that wearability is strong, tensile strength and that elongation at break is high, against weather is good etc. is excellent
Point, although at hardness, weight and Shortcomings in price, but in general, the application market of TPU is more
Extensively.
For now, " ClimaCoolTM " up-to-date series exploitation of Adidas (adidas) 360 degree
Gas venting system.The sole of these series of products, stiffener, protectiveness toe cap and shock absorbing part all have employed TPU
Elastomer.The fine mesh face of breathing freely of sole makes fresh air be able to from bottom and flows to shoes, meanwhile, special
Shoe pad plays the effect of fan, makes the air in footwear keep circulation, and its result is that the heat making generation decreases
20%.
Existing TPU be applied to footwear material produce employed in technique be TPU foam process, it is so-called that " TPU foams work
Skill ", it similarly is puffed rice in fact, TPU is made graininess, these granules can be thought of as one one old
Semen Maydis.Then throwing in a machine, this machine is similar to corn popper, then after High Temperature High Pressure,
These Semen Maydiss become puffed rice, use steam mould pressing process to be added by the puffed rice granule of about 2000 afterwards
Sole shape needed for work one-tenth, expanded beads outermost layer slightly melts and adhesion becomes to stablize shape in this process
Shape, internal porosity structure is unaffected simultaneously.After sole receives pressure, it is compressible to half size, significantly
Alleviating the shaking force that sole is born, after compression stress disappears, sole can be promptly restored to original shape.
Above TPU makes sole process and generally requires and purchase novel board, and needs to carry out long-time steam mould
Pressure, complicated process of preparation and cost and energy consumption are higher.
Summary of the invention
The present invention provides the preparation technology of a kind of PU puffed rice sole, to solve the problems referred to above.
