Abstract

The invention provides a material for rubber forming shoes and a preparation method of the material, relating to a rubber foaming material. The material for the rubber foaming shoes consists of the following raw materials in parts by mass: 100 parts of a main material, 1-5 parts of a vulcanizing agent, 1-4 parts of a vulcanizing adjuvant, 2-5 parts of a foaming agent, 8-15 parts of a plasticizer, 6-20 parts of a filler, 2-6 parts of a lubricant, 0-10 parts of an abrasion-resistant agent, 0.5-2 parts of an antioxidant, and 1.5-3 parts of pigment. The preparation method comprises the following steps of: mixing the raw materials according to the ratio into an internal mixer for mixing until a temperature of rubber is increased to 80-90 DEG C; discharging the mixed materials out the internal mixer, and pelleting through a pelleting machine; placing the pelleted material into an injection molding machine for fusing and vulcanizing; and molding through mould pressing, so as to obtain a product. The cost is low, the preparation method is simple, and the foaming rate and the rigidity are controllable; and the preparation method can be used for producing sandals, high-level beach shoes and the materials of insoles of sneakers, outsoles of leather shoes and the like. The material provided by the invention can replace the conventional shoe foaming material EVA (ethylene-vinyl acetate copolymer); and the defects of poor EVA strength, easiness of deformation, low cost performance and the like can be overcome.

Description

technical field [0001] The invention relates to a rubber foam material, in particular to a rubber foam shoe material and a preparation method thereof. Background technique [0002] The rubber foam material meets the requirements of low-carbon and environmental protection. It has the characteristics of light weight, softness, good elasticity, shock absorption, and chemical resistance. The finished product after injection molding does not release chemicals such as halogenated hydrocarbons, and does not contain European and American export restrictions Chemical substances, so the application field is very wide. Shoe materials are the most important application field of domestic EVA (ethylene-vinyl acetate copolymer) foam materials. EVA foam material has the characteristics of light specific gravity and comfortable wearing. It is mostly used in sports shoes, leather shoes, sandals and other substrates. Among them, EVA foam midsole material plays a pivotal role in the midsole ma...
