Embodiment 1
[0007] A rubber-like foamed shoe sole material formula, the weight ratio of the raw materials of the shoe sole material is: rubber 2.5kg, PE (polyethylene) scrap 10kg, EVA (ethylene and vinyl acetatecopolymer) scrap 5kg, filler 10kg, 0.1kg of dicumyl peroxide, 0.15kg of foaming agent, 0.45kg of foaming aid, 0.45kg of stearic acid, 0.1kg of vulcanizing agent, 0.07kg of anti-aging agent, and 0.2kg of pigment. The filler is CaCO 3 , the dicumyl peroxide is granular, the vulcanizing agent is an organic vulcanizing agent, the foaming aid is zincoxide, and the foaming agent is a powdered azo foaming agent.
Embodiment 2
[0009] A formula for imitating rubber foamed shoe soles, the weight ratio of the raw materials of the shoe soles is: 4kg of rubber, 15kg of PE scraps, 15kg of EVA scraps, 20kg of fillers, 0.13kg of dicumyl peroxide, foaming Agent 0.2kg, foaming aid 0.5kg, stearic acid 0.5kg, vulcanizing agent 0.13kg, anti-aging agent 0.1kg, pigment 0.4kg. The filler is CaCO 3 , the dicumyl peroxide is granular, the vulcanizing agent is an organic vulcanizing agent, the foaming aid is zincoxide, and the foaming agent is a powdered azo foaming agent.
Embodiment 3
[0011] A formula for rubber-like foamed shoe soles, the weight ratio of the raw materials of the shoe soles is: 3.2kg of rubber, 12.5kg of PE scraps, 7.5kg of EVA scraps, 15kg of fillers, and 0.12kg of dicumyl peroxide , foaming agent 0.17kg, foaming aid 0.47kg, stearic acid 0.47kg, vulcanizing agent 0.12kg, anti-aging agent 0.08kg, pigment 0.3kg. The filler is CaCO3, the dicumyl peroxide is granular, the vulcanizing agent is an organic vulcanizing agent, the foaming aid is zincoxide, and the foaming agent is a powdered azo foaming agent.
[0012] The technological process of adopting above-mentioned raw material to prepare sole material is:
[0014] Put the weighed rubber, PE scraps, and EVA scraps into an internal mixer for masticating. The masticating temperature is 100-120°C and the masticating time is 3min-5min.
[0015] 2. Mixing
[0016] CaCO 3 , ZnO, and pigments are weighed according to the amount in the formula, and then put into the mix...

Abstract
The invention provides a formula of imitative rubber foaming sole material. The sole material comprises the raw materials in the following proportion by weight: 25-40 parts of rubber, 100-150 parts of PE offal, 50-150 parts of EVA leftovers, 50-100 parts of filler, 1-1.3 parts of dicumyl peroxide, 1.5-2 parts of foaming agent, 4.5-5 parts of foaming promoter, 4.5-5 parts of stearic acid, 1-1.3 parts of vulcanizer, 0.7-1 part of antioxidant and 2-4 parts of pigment. The foaming rubber produced by the formula has low cost and has the same quality with the foaming rubber in the current market, and additionally, the foaming rubber produced by the formula also can effectively avoid the phenomenon of easy dust accumulation and combustion in the existing foaming rubber machining process when thefoaming rubber produced by the formula is processed, and improves the safety and the environment protection characteristics of production.
Description
technical field [0001] The invention relates to the technical field of shoe materials, in particular to a formula for imitating rubber foamed shoe soles. Background technique [0002] At present, there is a problem that dust is easy to accumulate and burn during the processing of foamed rubber prepared by traditional formula in shoe factories, and there is a problem of low quality of foamed rubber prepared from leftovers as shoe materials. Contents of the invention [0003] The object of the present invention is to provide a rubber foam shoe sole material formula, which avoids the phenomenon that dust is easy to accumulate and burn during the processing of foam rubber, and improves production safety and environmental protection characteristics. [0004] A kind of imitation rubber foaming sole material formula of the present invention is characterized in that: the weight proportion of raw material of described sole material is: 25-40 parts of rubber, 100-150 parts of PE scr...
