Abstract

The invention belongs to the technical field of organic high-molecular compounds, and in particular relates to a high-elasticity light-weight rubber-plastic foam material with good wear resistance and a preparation method of the foam material. The high-elasticity light-weight rubber-plastic foam material is prepared from the following raw materials in parts by weight: 60-70 parts of EVA (ethylene vinyl-acetate copolymer), 10-20 parts of NR (natural rubber), 10-20 parts of EPDM (ethylene-propylene-diene monomer), 5-7 parts of an abrasion-resistant agent, 2-4 parts of an active agent, 2-4 parts of a lubricating agent, 0.8-1.2 parts of a bridging agent, 1.5-2 parts of a foaming agent, 1-2 parts of ST flocculant and 3-5 parts of CaCO3. The high-elasticity light-weight rubber-plastic foam material has good wear resistance and elasticity and small specific gravity, and is particularly suitable for being applied to soles and the like, so that comfort property is good and service life is long.

Description

technical field [0001] The invention belongs to the technical field of organic polymer compounds, and in particular relates to a light-weight, highly wear-resistant, high-elastic rubber-plastic foaming material and a preparation method thereof. Background technique [0002] At present, rubber and plastic foam materials are widely used in daily life and industry, such as the most common use for making shoe soles, heat preservation, and heat insulation materials. For example, the rubber and plastic foam materials currently used for shoe soles, the most basic requirements of the market are better comfort and longer service life, but at present, the rubber and plastic foam materials used for shoe soles often have the following disadvantages : 1) The proportion is large, and the feeling of wearing is relatively cumbersome; 2) The wear resistance is poor, and the service life is short, which is not suitable for some shoes with high wear resistance requirements; 3) The elasticity i...
