Abstract
The invention relates to an anti-yellowing thermoplastic elastomer for a shoe upper. The anti-yellowing thermoplastic elastomer for the shoe upper mainly comprises 78-85 wt% of styrene TPE, 5-13 wt% of butadiene-acrylonitrile rubber, 5-10 wt% of flexibilizer and 0-3 wt% of processing aids. After the materials are mixed according to the certain proportion and evenly stirred, the granular thermoplastic elastomer is prepared from the materials through a twin-screw granulator. According to the anti-yellowing thermoplastic elastomer for the shoe upper, the styrene TPE serves as the main material, and the styrene TPE is cooperated with the butadiene-acrylonitrile rubber and the flexibilizer to prepare the thermoplastic elastomer with more excellent anti-yellowing effect through the twin-screw granulator; the shoe upper injection-molded through the thermoplastic elastomer is bright in surface and color; compared with the shoe upper prepared from TPU, the shoe upper prepared from the thermoplastic elastomer is more light and convenient, shorter in injection molding time, better in anti-yellowing effect and specially suitable for being made into the shoe uppers of tourist shoes, sports shoes, fashion shoes and the like.
Description
Technical field
The present invention relates to vamp material field, in particular a kind of color inhibition thermoplastic elastomer for making vamp.
Background technology
polyurethanes TPE is by the thermoplastic polyurethane rubber be combined with polyester or the mutual block of polyether soft segments with the ammonia ester hard segment of isocyanate reaction.Polyurethanes TPE is called TPU for short again, and have excellent physicals, wear resistance, oil-proofness and flexible resistance, particularly wear resistance is the most outstanding.Be widely used at present for the manufacture of ski boots, nailed climbing boots, various sports shoes, sneakers etc., but adopt the vamp of the direct injection moulding of TPU under solar exposure, easily turn yellow, have a strong impact on its aesthetic property, define its range of application and work-ing life.
Summary of the invention
The object of the present invention is to provide a kind of color inhibition thermoplastic elastomer for vamp improving injection moulding efficiency, color inhibition better effects if.
For a color inhibition thermoplastic elastomer for vamp, main containing following component: styrenic TPE78-85wt%, paracril 5-13wt%, toughner 5-10wt% and processing aid 0-3wt%d; Granular thermoplastic elastomer is made by dual-screw pelletizer by after above-mentioned materials mixing and stirring.
Preferably, described styrenic TPE is the multipolymer of styrene-butadiene-styrene block type.
Preferably, described processing aid comprises Zinic stearas, polyethylene wax and silicone oil.
Preferably, the proportioning of described material is: styrene-butadiene-styrene block copolymer 78wt%, paracril 13wt%, toughner 7wt%, Zinic stearas 0.5wt%, polyethylene wax 0.5%, silicone oil 1wt%.
Preferably, the proportioning of described material is: styrene-butadiene-styrene block copolymer 80wt%, paracril 10wt%, toughner 8wt%, Zinic stearas 0.6wt%, polyethylene wax 0.6%, silicone oil 0.8wt%.
Preferably, the proportioning of described material is: styrene-butadiene-styrene block copolymer 84wt%, paracril 5wt%, toughner 10wt%, Zinic stearas 0.3wt%, polyethylene wax 0.3%, silicone oil 0.4wt%.
Adopt the above-mentioned color inhibition thermoplastic elastomer for vamp as starting material, be injection molded into the vamp of setting shape by injector, described vamp is light face.
Especially the product colour made of styrene-butadiene-styrene block copolymer is bright-coloured, proportion is lighter and injection molding cycle is shorter for styrenic TPE; Paracril has excellent oil-proofness, thermotolerance is better, cohesive force is strong; MBS toughner (MBS resin) is methyl methacrylate (M), divinyl (B), vinylbenzene (S) terpolymer, under the prerequisite of harmless rosin products natural characteristics, its shock strength can be improved, there is the advantage that transparent and ultraviolet-resistant aging etc. are outstanding.
The present invention adopts styrenic TPE as main raw, paracril and toughner is coordinated to make the more excellent thermoplastic elastomer of color inhibition effect, it is bright by the vamp of this thermoplastic elastomer injection moulding, bright-colored, the bright inclination of striped, its hardness, the vamp that wear resistance and screen resilience and TPU make has no gap, but the injection molded vamp quality of the present invention can be lighter, density is 75% of TPU vamp density, the injection moulding required time consumed is shorter, the injection time of 1/3 can be saved, color inhibition better effects if, be specially adapted to be made into sneakers, sports shoes, the vamp of dress shoes etc.
What the present invention made the color inhibition test employing of vamp is ASTMD1148-95 (2001) standard, namely ultraviolet light source has been adopted, under the physical environment of constant temperature simulation, the change that sample surfaces color occurs is observed in specific time, determine the discoloration of sample, in the present invention, the physical environment of experimental simulation irradiates the time that namely one day be equivalent to six months in physical environment; Test experiments shows, general T PU vamp irradiates and namely starts variable color in 2 hours, and the present invention makes vamp and needs irradiation to reach 36 hours just to start variable color, and the effect of its color inhibition is far superior to TPU vamp, improves the work-ing life of shoes.
