Problems solved by technology

[0002] Shoes with good air permeability can maintain a dry micro-climate in the shoe cavity for a long time, so that the skin of the feet can breathe freely and ensure the health of the feet; on the contrary, shoes with poor air permeability are not easy to discharge the sweat secreted by the feet in time, forming a damp sweat in the shoes. environment, it is easy to breed mold, produce moldy odor and suffer from beriberi, and the long-term lack of oxygen on the skin of the feet will weaken the body's resistance, and chronic bacteria can easily invade the human body, leading to colds, arthritis and other diseases. People's work and daily life bring a lot of inconvenience, so the research on the breathability of footwear is of great significance

Embodiment 1

[0019] Put 150g of SBS, 90g of 1,2 polybutadiene, 50g of polystyrene, 175g of paraffin oil, and 35g of calcium carbonate with a particle size of 0.1-1μm into the compactor for compacting. The temperature is controlled at 130°C for 15 minutes. The refined mixture is put into a single-screw granulator for granulation (the temperature is controlled at about 100°C), and then the prepared granules are poured into the disc rotary injection molding machine through the feed hopper, and the temperature is controlled at the inlet temperature of 130°C. In a gradient field where the outlet temperature is 150°C, the injection pressure is 50kg / cm 2 , the back pressure is 5kg / cm 2 , injection molding.

[0020] Cut the foamed EVA sheet according to the size of the sole to make a bottom pad, and set air holes on the bottom pad, and then place the bottom pad on the above-mentioned sole to form a complete shoe sole. The ventilation holes in the bottom pad promote the free circulation and excha...

Embodiment 2

[0023] Put 140g of SBS, 80g of 1,2 polybutadiene, 45g of polystyrene, 170g of paraffin oil, and 65g of calcium carbonate with a particle size of 0.1 to 1 μm in a compact mixer. The temperature is controlled at 120°C for 15 minutes. The refined mixture is put into a single-screw granulator for granulation (the temperature is controlled at about 100°C), and then the prepared granules are poured into the disc rotary injection molding machine through the feed hopper, and the temperature is controlled at the inlet temperature of 130°C. In a gradient field where the outlet temperature is 150°C, the injection pressure is 45kg / cm 2 , the back pressure is 5kg / cm 2 , injection molding.

[0024] The air permeability detection method of the breathable sole is the same as that in Example 1, and the test results are shown in Table 1.

Embodiment 3

[0028] Put 160g of SBS, 100g of 1,2 polybutadiene, 55g of polystyrene, 180g of paraffin oil, and 5g of calcium carbonate with a particle size of 0.1 to 1 μm in a compact mixer. The temperature is controlled at 135°C for 10 minutes. The refined mixture is put into a single-screw granulator for granulation (the temperature is controlled at about 100°C), and then the prepared granules are poured into the disc rotary injection molding machine through the feed hopper, and the temperature is controlled at the inlet temperature of 130°C.

Abstract

The invention relates to an air-permissible sole material and a method for preparing air-permissible soles by the material, relating to a sole material and a method for preparing the soles by the material. The invention provides an air-permissible and water-proof sole material and a method for preparing the air-permissible soles which have good ventilation property and good wear-resistance, twist-resistance and anti-slipping functions. The composition of the sole material is rubber, 1, 2-polybutadiene, polystyrene, a lubricant and filler. The rubber, the 1, 2-polybutadiene, the polystyrene, the lubricant and the filler are mixed and put into an internal mixer for internal mixing; then, the internally mixed mixture is put into a granulator for granulation; and finally, the granules of the mixture are injected into sole moulds for injection molding by an injection molding machine. The sole material can provide passages and media necessary for ventilation; when falling on the ground, the pressure can cause vapor in shoe cavities to flow to the outside; when leaving the ground, the negative pressure causes the outside air to flow into the shoe cavities, therefore, the free-breathing of feet is realized and the soles have good wear-resistance, twist-resistance and anti-slipping performance.
