Abstract

The invention discloses a sponge rubber sole material which is characterized by comprising the following components in parts by weight: 50-70 parts of a labeling adhesive, 30-50 parts of butadiene rubber, 3-8 parts of zinc oxides, 1-2 parts of a stearic acid, 0.5-1.5 parts of a promoter M, 1-1.5 parts of a rubber accelerator DM, 1-2 parts of an antiager, 25-35 parts of carbon black N550, 30-40 parts of a nano rubber reinforcing agent, 20-30 parts of white oil, 8-12 parts of phenolic resin, 3-5 parts of a foaming agent, 1-3 parts of baking soda, and 1-3 parts of sulfur. According to the invention, products are high in plasticity, the plasticity is over 0.55, the elongation of products is over 420%, the strength is over 8.2 Mpa, the density is 0.65-0.66, and the hardness measured by using a shore type D hardness tester is 44-46 degrees.

Description

technical field [0001] The invention relates to a rubber material and a preparation method thereof, in particular to a sponge rubber bottom material and a preparation method thereof. Background technique [0002] Sponge rubber is a porous rubber obtained by adding an appropriate amount of foaming agent to the rubber to decompose the foaming agent to generate gas while vulcanizing the rubber. Sponge rubber materials are generally used in sealing, shock absorption, noise reduction and other fields. The sole made of sponge rubber material is light and comfortable. [0003] As a shoe sole, the performance requirements of the sponge rubber bottom material are higher, not only need to be light and comfortable, but also meet the requirements of strength, hardness and elongation. The existing sponge rubber bottom material is difficult to meet the requirements of lightness and softness, certain elongation and strength, so the service life is relatively short, and it is easy to defo...
