preparation example Construction
[0028] The preparation method of injection imitation PU foaming sports shoe sole mainly comprises 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 other materials together.
[0031] 2) Banbury
[0032] Pour the prepared raw materials except DCP and AC-6000H into a 75-liter internal mixer, and start the internal mixer to mix the materials evenly. The mixing time of the first stage is 7-8 minutes, and the number of material turning is 4-5 times. When the temperature reaches 110°C-112°C, add DCP and AC-6000H, and start the mixer again. The banburying time of the second stage is 2-3 minutes, and the number of times of material turning is 2-3 times. When the temperature continues to rise to 115°C-118°C, all raw materials have been mixed evenly, and the materials are poured out for kneading.

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, non-slip and long service life and a manufacturing method thereof. Background technique [0002] China is the world's largest shoe manufacturer and exporter, and there are all kinds of shoe 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 hydrolysis and short service life, these shortcomings have made PU in the market. share is decreasing. Therefore, improving these deficiencies of PU materials and finding and developing its substitutes are the direction and inevitable trend of shoe material development. Sports has entered the life of each of us, and it has also made sports shoes used in every environment of human life, especially in environ...
