Material for high-wear-resistant rare earth rubber shoes and preparation method thereof

Abstract

The invention discloses a material for high-wear-resistant rare earth rubber shoes and a preparation method thereof. The material is prepared from rare earth polybutadiene rubber (NdBR), isoprene rubber (IR), solution polymerized butadiene styrene rubber (SSBR), a softening agent, an activating agent, a coupling agent, a vulcanizing agent, a vulcanization accelerator, an anti-aging agent and surface modified ground rubber. The invention adopts a die pressing method to prepare a series of rubber shoe sole materials with wear resistance (DIN wear is 30 to 120mm<3>), slip limit (dry slip is 0.6 to 1.1, and wet slip is 0.3 to 0.6), and moderate hardness (Shore A) 60 to 70; the material has the following advantages that (1) the wear resistance is better; (2) the slip limit is improved; (3) the comfort is increased; (4) the production cost can be remarkably reduced, the profit space is improved, and the energy is saved.

Description

technical field [0001] The invention relates to a material for high wear-resistant rare earth rubber shoes and a preparation method thereof. The material is suitable for middle and high-grade shoe outer soles integrating wear resistance, anti-slip and comfort. Background technique [0002] With the development of science and technology and the progress of society, people's living standards are constantly improving. Improving the quality and performance of all kinds of shoes and making the wearers safer and more comfortable is the ultimate goal and direction of the development of the entire shoe industry. The research and development of a high-performance sole material integrating wear resistance, anti-skid and comfort has become a hot spot in the shoe industry. Due to its excellent wear resistance and anti-slip properties, rubber soles still have an irreplaceable important position in the field of shoemaking under the background of the emergence of a large number of function...

AI Technical Summary

Problems solved by technology

[0008] At present, the rubber outsoles of mid-to-high-end footwear that require high wear resistance and pursue comfort have the following problems: the widely used solid rubber outsoles have ideal wear resistance, but have a large specific gravity (density between 1.20-1.30g / cm 3 ), high hardness and poor wet skid resistance

[0012] The above invention and research on butadiene rubber soles mainly use traditional nickel-based butadiene rubber. Although it has good wear resistance, it has poor wet skid resistance. and isoprene rubber used in the field of footwear is less reported
