Polymer composite lightweight rubber and preparation method thereof

Abstract

The invention belongs to the technical field of new materials and in particular relates to polymer composite lightweight rubber and a preparation method thereof. The rubber comprises the following components in parts by weight: 50-100 parts of SBR (styrene butadiene rubber), 10-50 parts of SEBS (styrene-ethylene/butylene-styrene elastomer), 5-30 parts of crystalline 1,2-polybutadiene resin B, 5-30 parts of vinyl acetate, 5-20 parts of white mineral oil, 5-30 parts of cis-polybutadiene and 20-50 parts of elastomer. The rubber and the preparation method have the beneficial effects that the rubber has excellent properties as traditional vulcanized rubber, such as high elasticity, aging resistance, high wear resistance and oil resistance, also has the independent characteristics of high property, light specific gravity, flex resistance, high pressure resistance and no vulcanization and can be produced by adopting the processing methods, such as injection molding, extrusion and blow molding; wastes (extruded waste rubber and raw edges) generated in the production process and finally emerging wastes can be directly returned and recycled, thus reducing the cost and environmental pollution and expanding the resource regeneration sources.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a polymer composite lightweight rubber and a preparation method thereof. Background technique [0002] The main materials for the production of soles are rubber, PU, ​​PVC, MD, TPR, TPU, EEVA, etc. Rubber soles are widely used in footwear due to their advantages such as non-slip, high elasticity, good wear resistance, not easy to break, good elongation, and stable shrinkage. It can be said that it occupies half of the country in the finished products. At present, most of the finished shoes of domestic first-line brands use rubber soles, but the disadvantage of rubber soles is that the formula cost is low, and the physical properties are not satisfactory.

Problems solved by technology

[0002] The main materials for the production of soles are rubber, PU, ​​PVC, MD, TPR, TPU, EEVA, etc. Rubber soles are widely used in footwear due to their advantages such as non-slip, high elasticity, good wear resistance, not easy to break, good elongation, and stable shrinkage. It can be said that it occupies half of the country in the finished products. At present, most of the finished shoes of domestic first-line brands use rubber soles, but the disadvantage of rubber soles is that the formula cost is low, and the physical properties are not satisfactory. If you want to make high-quality soles, the rubber soles used The cost of rubber formula is generally higher

For every 100 grams increase in the weight of the shoe, the physical energy consumption will increase by 1%. High elasticity and light weight are the current development direction of rubber sole materials. Although rubber materials have strong elasticity, their quality is relatively heavy. In order to achieve the purpose of light weight, At present, most of them use EEVA and other materials to replace rubber materials to solve the problem of lightweight. However, although EEVA foam soles and PU soles are light in weight, they have poor anti-slip effects, fast aging, and high cost.

[0003] Traditional rubber needs to be vulcanized in order to make it have high elasticity, aging resistance, high wear resistance and oil resistance, but vulcanization is not friendly to the environment
