Wear resistant sole material

Abstract

The invention relates to a wear resistant sole material. The wear resistant sole material comprises, by weight, 35-45 parts of EVA, 4-8 parts of styrene butadiene rubber, 1-8 parts of butadiene rubber, 1-4 parts of a vulcanizing agent, 2-5 parts of a reinforcing agent, 1-4 parts of an activator, 1-4 parts of an accelerant and 0.5-3 parts of a foaming agent. The wear resistant material greatly improves the wear resistance of a sole without influencing the elasticity, the resilience, the portability or the like of the sole, and also has the advantages of non-toxicity, no pollution, safety and environmental protection.

Description

technical field [0001] The invention relates to a wear-resistant shoe sole material. Background technique [0002] Abrasion resistance is an important indicator of rubber products, such as rubber tires, seals, conveyor belts, piston rings and shoe soles, etc. During use, friction and wear will inevitably occur, which are closely related to material failure and safety. China is In a big shoe-producing country, the consumption is also very considerable. Improving the wear resistance of rubber soles can bring considerable economic and social benefits. [0003] The development of new anti-wear materials has two notable features: the first is the development from a single material to a composite material, adding reinforcement materials such as particles, whiskers and fibers to the material to improve wear resistance; the second is the use of modern surface technology to manufacture High performance wear resistant material. At present, people are more inclined to the research an...

Problems solved by technology

[0004] Due to the simple dry mixing process and convenient production, the rare earth particles cannot be evenly distributed in the raw rubber, especially when the rare earth content is high, the rare earth particles are prone to local agglomeration and cause stress concentration, which reduces the strength of the sample. Reduced abrasiveness

The most important point is that the price of rare earths is relatively high, adding rare earth oxides to the soles increases the cost of footwear products

At the same time, due to the poor compatibility between commonly used inorganic substances and organic substances, it is difficult to ensure a good affinity between the two-phase interface of the composite material. When the amount added is greater than a certain value, the wear resistance of the material will decrease instead. In the rubber bond, due to the insufficient adhesion of large-sized particles to the bond and the formation of "micro-cracks" around the surface of the particles in the rubber bond during the vulcanization process, the combination of abrasive particles and rubber is not firmly held
