preparation example Construction
[0028] The preparation method of the injection imitation PU foamed sports shoe sole mainly includes the following steps:
[0029] 1) Pound material
[0030] Weigh the raw materials according to the designed formula, bag the bridging agent and high temperature foaming agent separately, and mix the other materials together.
[0031] 2) Tantra
[0032] Pour the prepared raw materials into a 75-liter internal mixer, except for DCP and AC-6000H, start the internal mixing and mixing to make the materials evenly mixed. The banburying time of the first stage is 7-8 minutes, and the frequency of turning is 4-5 times. When the temperature reaches 110°C-112°C, add DCP and AC-6000H and start the internal mixing process again. The second stage of banburying time is 2-3 minutes, and the number of turning materials is 2-3 times, until the temperature continues to rise to 115°C-118°C, all the raw materials have been mixed uniformly, and the materials are poured out for smelting.

Abstract
The invention relates to a formula of soles of PU-simulated foaming sneakers through injection, which comprises the following raw materials in percentage by mass: 40 percent of 21 percent ethylene-vinyl acetate copolymer (EVA 7360), 16.7 percent of styrene butadiene copolymer SBBSJT-83, 12.5 percent of ethylene octylene copolymer POE8130, 8.3 percent of ethylene-propylene-diene copolymer 3745P, 65.9 percent of wear-resisting agent A-18, 8.3 percent of talcpowder, 0.25 percent of stearic acid, 0.42 percent of zinc stearate, 0.9 percent of zinc oxide, 0.08 percent of bridging auxiliary agent ET-102, 0.75 percent of bridging agent DCP, 1.7 percent of high-temperature foaming agent AC-6000H, 2.5 percent of titanium white powder R-103 and 1.7 percent of master batch. The preparation method comprises the steps of banburying, mixing, granulation, injection molding, physical property tests and the like. Thus, in the research and development and application, the PU-simulated foaming soles not only have the physical and chemical properties of no crease marks, high elasticity, low compression and wear resistance of PU soles, and but also have the advantages of low production cost, light specific gravity, good limited-slip properties, no hydrolysis and long service life.
Description
Technical field [0001] The invention relates to a special sports shoe sole, in particular to a foam sole formula with PU texture, anti-slip and long service life, and a manufacturing method thereof. Background technique [0002] China is the world's largest producer and exporter of footwear, with all kinds of footwear materials, among which polyurethane PU soles are all the rage. Its good wear resistance, good elasticity, strong folding resistance and unique texture have been praised and recognized by many consumers; but its high unit price, high density, non-slip, easy to hydrolyze and short service life, these shortcomings have made PU in the market The market share is getting less and less. Therefore, it is the direction and inevitable trend of shoe material development to improve these shortcomings of PU material and find and develop its substitutes. Sports have entered each of our lives, and sports shoes have also been used in every environment where humans live, especiall...
