Embodiment 1

[0035] A composite foam injection midsole, the raw materials of which include:

[0036]

[0037] Step 1: Put the weighed main materials (EVAC, OBCS, POE), filling materials, catalyzers, colorants, and lubricants into the internal mixer according to the proportion and mix them for 7 minutes. When the temperature rises to 100 degrees, add cross-linking agent and foaming agent, mixed for 2 minutes, the temperature is 110 degrees, and the material is put into the open mixer. Extrusion granulator, the temperature of the die head of the granulator is 80 degrees, the temperature of the barrel is 75 degrees, and the particle size is 3mm. The prepared pellets need to stand at room temperature for 3 hours.

[0038] The second step: dry the pellets, put the static pellets into the drying barrel for 2 hours, the drying temperature is 50 degrees,

[0039] Step 3: The pellets are automatically pumped into the injection gun by the injection machine and injected according to the set weigh...

Abstract

The invention discloses a composite injection foaming rubber midsole material and a manufacturing method thereof. The material comprises the following raw materials in parts by weight: 25-35 parts of EVA (ethylene-vinyl acetate) C1 (26-28% of VA), 5-15 parts of EVA C2 (40% of VA), 25-35 parts of OBCS, 25-35 parts of POE (polyolefin elastomer), 3-5 parts of anti-wear agent, 2-4 parts of nano calcium carbonate, 0.8-1.0 part of ZNO, 0.7-0.8 part of zinc stearate, 1-2 parts of R-103, 5-10 parts of toner, 0.4-0.5 part of stearic acid, 1.1-1.2 parts of DCP (dicumyl peroxide) and 0.8-0.85 part of AC. The material can be directly used in an EVA injection technique.

Description

technical field [0001] The invention relates to the field of shoe manufacturing, in particular to a novel polymer composite foam material injection midsole and a manufacturing method. Background technique [0002] The structure of the sole is quite complex. In a broad sense, it can include all the materials that make up the bottom, such as the outsole, midsole and heel. Among the midsoles of sneakers, PHYLON midsoles and EVA midsoles are the most common. Now the most used midsole in shoes is PHYLON midsole. The biggest feature of PHYLON is lightness, good elasticity, and good cushioning performance. PHYLON is called secondary foaming. The EVA midsole is also very light, but the cushioning performance and elasticity are far inferior to the PHYLON midsole, and the cost is much lower than that of the PHYLON. The EVA midsole is called primary foaming. [0003] At present, the foamed rubber material in the market can only be injected with a special rubber injection machine, whi...
