High-wear-resistance elastic polymer rubber material and preparation method thereof

Abstract

The invention discloses a high-wear-resistance elastic polymer rubber material and a preparation method thereof. The high-wear-resistance elastic polymer rubber material is characterized by being composed of a rubber composition and rubber auxiliaries. The rubber composition comprises an ethylene-vinyl acetate copolymer, ethylene-propylene-diene monomer rubber, SEBS, a POE elastomer and an ethylene-octylene segmented copolymer. The rubber auxiliaries comprise a wear resisting agent, a foaming agent, a vulcanizing agent, a softener, an accelerant, a reinforcing agent and other auxiliaries. According to the preparation method, the finished product is obtained through the steps of batching, banburying, mixing, open milling and pelleting. The compatible and complementary factors existing between all types of synthetic rubber are utilized, so that the obtained high-wear-resistance elastomer sole material has high elasticity, high flexibility, high wear resistance and good mechanical performance, is low in cost and can be widely applied to the fields of soles, insoles and the like.

Description

technical field [0001] The invention belongs to the technical field of rubber processing, in particular to a production formula of a highly wear-resistant elastic foamed rubber material and a preparation method thereof. Background technique [0002] There are many types of rubber materials available in the market today, and the requirements for materials include a wide range of operating temperatures, resistance to chemicals and oils, and so on. Among them, soles with comfort, light weight, wear resistance, high elasticity, low permanent compression and low price are more and more sought after by people. Tracing back the development of rubber materials from natural rubber at the beginning, then PVC synthetic leather and synthetic rubber, and later EVA, PU, ​​SBS, TPU and their corresponding foaming materials. However, these materials often cannot meet people's requirements for rubber materials. Careful analysis of these materials will reveal that natural rubber has poor lo...

Problems solved by technology

However, these materials often cannot meet people's requirements for rubber materials.

Careful analysis of these materials will reveal that natural rubber has poor low temperature resistance, heavy taste, and uncomfortable texture; PVC synthetic leather hardens at low temperature, has poor comfort, is not wear-resistant, and has poor elasticity; synthetic rubber such as vulcanized rubber has a strong taste , high density; EVA material has poor wear resistance and large compression deformation; PU synthetic leather has excellent wear resistance and light weight, but relatively high price; SBS needs to improve wear resistance, large compression deformation, and poor weather resistance; TPU material is expensive , hard and uncomfortable
