Embodiment 1
[0022] A kind of starch ethylene-vinyl acetate composite foaming agent shoe sole material, comprises by weight
[0029] The preparation method of described modified starch is as follows:
[0030] Dissolve starch in water, heat to 85°C, gelatinize for 20 minutes, then cool to below 60°C, add ammoniumpersulfate initiator, then add vinyl acetate monomer, react at 60°C for 5 hours, add absolute ethanol for precipitation , filtered, and dried to obtain grafted modified starch.
Embodiment 2
[0032] A kind of starch ethylene-vinyl acetate composite foaming agent shoe sole material, comprises by weight
[0041] The preparation method of described modified starch is as follows:
[0042] Dissolve starch in water, heat to 95°C, gelatinize for 40 minutes, then cool to below 60°C, add ammoniumpersulfate initiator, then add vinyl acetate monomer, react at 80°C for 5 hours, add absolute ethanol for precipitation , filtered, and dried to obtain grafted modified starch.
Embodiment 3
[0044] A kind of starch ethylene-vinyl acetate composite foaming agent shoe sole material, comprises by weight
[0053] The preparation method of modified starch of the present invention is as follows:
[0054] Dissolve starch in water, heat to 90°C, gelatinize for 30 minutes, then cool to below 60°C, add ammonium persulfate initiator, then add vinyl acetate monomer, react at 70°C for 3 hours, add absolute ethanol for precipitation , filtered, and dried to obtain grafted modified starch.
[0055] The shoe sole material described in Examples 1-3, after being prepared into a shoe sole, its wear resistance is greatly improved, and its density is at least 0.085g / cm 3 , even without using gr...

technical field [0001] The invention relates to the technical field of shoe sole materials, in particular to a modified starch ethylene-vinyl acetate composite foaming agent wear-resistant shoe sole material. 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. In a narrow sense, it only refers to the outsole. The common characteristics of general sole materials should be wear-resistant, water-resistant, oil-resistant, heat-resistant, pressure-resistant, impact-resistant, good elasticity, easy to fit the shape of the foot, and not easy to change after being shaped. Heat preservation, easy to absorb moisture, etc., and at the same time, it must cooperate with the midsole, which has a braking effect when walking and changing feet, so that it will not slip and is easy to stop. There are many types of sole materials, which can be divided into n...
