Description
Technical field
The present invention relates to the sole materials and preparation method thereof of shock-absorbing rebound, and in particular to one kind is main glue by POE and EVA
The sole material and preparation method thereof for the shock-absorbing rebound being prepared.
Background technique
In order to improve the achievement of sportsman, sport footwear must be light as far as possible, so ultralightization of sport footwear and its excellent property
Being able to maintain property just becomes the Main way of movement midsole material development.One vinyl acetate co-polymer of ethylene (EvA) foaming shoe
Bottom material is because of its widespread love light, comfortable and easy to wear by people.EVA has good plasticity, fabulous elasticity, institute
With, EVA in movement midsole using extremely widespread.The middle bottom material of the various branding campaign shoes in the whole world is mostly to use
EvA and its foamed material with resin, the blend of rubber.High-elastic is the test item of a conventional need in fact, and damping
Performance G value is the footwear material of characterization movement in recent years comfortably with the important indicator of safety, and damping performance G value is test footwear material by outer
The number of footwear material Displacement-deformation when the impact force on boundary, the smaller damping performance of Displacement-deformation is better.
Ethylene-vinyl acetate copolymer (EVA) is the thermoplastic of rubber like, is had compared with polyethylene excellent
Flexibility, cold flexibility, elasticity, stress cracking resistance and good plasticity, machinability, therefore obtain extensively
Application.EVA crosslinked foaming material is the foamed material that a kind of physical property is excellent, nontoxic, due to the presence of gas phase, with density
It is low, specific strength is high, can absorb the advantages that load.But the deformation of EVA foamed material is big, and wearability is inadequate, and exists and skid, is low
The shortcomings that temperature is hardened, to limit its application.
In recent years, more to the research of EVA crosslinked foaming material both at home and abroad, mainly formula and processing technology are set
Meter, wherein the important channel that modifying agent is formula design is added.Thermoplastic polymer such as thermoplastic elastomer (TPR), ternary
EP rubbers (EPDM) etc. is commonly used for the modifying agent of EVA crosslinked foaming, and EPDM has excellent ageing-resistant performance, 110~16
0 DEG C of blend (EVA/EPDM) that can be obtained with EVA melt blending in amorphous areas partially compatible, in peroxide initiator
Under the action of, compatibility can be improved, but its viscosity is increased with the increase of EPDM amount, cannot guarantee to squeeze out well
With going on smoothly for injection technique, by biggish limitation in production application.Ethylene-octene copolymer (POE) in addition to
Have outside elasticity, recovery, obdurability and weatherability as traditional rubber, molding is equally easily worked also like thermoplastic
It is reused with recycling, and there is splendid compatibility with other plastic raw materials.The product not high to temperature classification is directly used
POE can machine-shaping, can not only improve production efficiency by a relatively large margin, can also reuse；And narrow average molecular
Mass Distribution makes material be not likely to produce flexure in injection and extrusion process；Its strand saturation, contained tertiary carbon atom is relatively
It is few, thus there is excellent heat-proof aging and anti-ultraviolet property.Therefore POE modified EVA is used, function admirable, hard can be made
Spend foaming product in extensive range.
The wear-resisting foaming shoe material of the ultralight damping of prior art Chinese invention patent and its manufacturing method, application No. is
CN201810819029.0, it discloses footwear material groups to become ethylene-vinyl acetate copolymer 0%~30%, polymer polyol
Alcohol 37%~68%, polyolefin block copolymer 10%~20%, ethylene-acrylic acid copolymer 5%~15%, anti-wear agent 5%
~10%, talcum powder 3%~8%, stearic acid 0.2%~0.6%, zinc stearate 0.3%~1.0%, zinc oxide 1.0%~
2.0%, two-(tert-butylperoxyiso-propyl) benzene 0.4%~0.6%, azodicarbonamide 4%~6%, Masterbatch 2%~
3%, gross mass 100%.The prepared wear-resisting foaming shoe material of ultralight damping had not only reached ultralight, damping comfort property, but also reached resistance to
Mill, wearing well requires, and in embodiment 4, damping G value is 8.3, rebound degree 58%.
