Abstract
The invention discloses an SPU (Silicate PolyUrethane) sole material with high polymerization degree. The SPU sole material comprises the following ingredients in weight percentage: 45-50% PVC, 35-45% DOP, 0.8-1% Ca/Zn complex stabilizer, 1-2% auxiliary stabilizer, and 4-13% CaCO3. The SPU sole material provided by the invention has higher resilience, lower compressive deformation, higher tensile strength, and superior abrasion resistance, heat resistance, and cold resistance.
Description
Technical field:
The present invention relates to footwear material technical field, relate in particular to a kind of SPU material for sole of shoe.
Background technology:
As everyone knows, made in China footwear are all over the world.The footwear annual production of China surpasses 10,000,000,000 pairs, accounts for 45% of global footwear output.The footwear industry volume of retail sales reaches 3,000 hundred million yuans.In recent years because the rubber overshoes industry begins to pursue high quality, pay attention to rubber overshoes comfortable and easy to wear, attractive in appearance, anti-skidding, the life-span is long, and bigger variation is also arranged on materials.The material for sole of shoe development is very fast, from initial solid material, and foam materials PVC, PU by now, thermoplastic elastomer etc.For meeting the need of market, all material for sole of shoe all develop towards physicals excellence, direction merrily and lightheartedly comfortable, easy to process.
High-polymerization degree SPU winter hardiness is good, flexible, bending fatigue strength is big, frictional coefficient is big, is mainly used in injection moulded shoes, sports shoes, at the bottom of labour protection footwear and the leather shoes.Better than foam materials PVC sole wear resistance, equally also overcome the SBS material for sole of shoe and met the shortcoming that thermal capacitance easily bends.
Summary of the invention:
The purpose of this invention is to provide a kind of high-polymerization degree SPU material for sole of shoe, the SPU sole that is made by this material has higher resilience, lower compression set, higher draw tensile strength and good wear resistance, thermotolerance, winter hardiness.
Purpose of the present invention is achieved through the following technical solutions:
A kind of SPU sole sizing agent comprises following component by weight percentage:
Preferred as technique scheme, the content of described SPU is 47-50%.
Preferred as technique scheme, described DOP is dioctyl phthalate (DOP), its main component is Tetra hydro Phthalic anhydride and 2-Ethylhexyl Alcohol.
Preferred as technique scheme, described calcium zinc stabilizer is less fatty calcium salt and the zinc salt of carbon number that is soluble in organic solvent, and main component has calcium stearate, ricinolic acid calcium, Zinic stearas, zinc ricinate and epoxy soybean oil, UV light absorber.
Preferred as technique scheme, described auxiliary stabilizer is one or more mixtures in phosphorous acid esters, epoxies, two ketones.
Beneficial effect of the present invention is: SPU material for sole of shoe of the present invention has higher resilience, lower compression set, higher draw tensile strength and good wear resistance, thermotolerance, winter hardiness.
Embodiment:
