Abstract

The invention discloses a foamed rubber sole special rubber material and a preparation method thereof. The rubber material is made of the following raw materials by weight: 45-65 parts of bromobutyl rubber, 35-45 parts of acrylate rubber, 5-10 parts of ethylene-vinyl acetate copolymer, 4-8 parts of dipentamethylene thiuram tetrasulfide, 3-6 parts of dicumyl peroxide, 1-4 parts of vulcanizing agent, 3-7 parts of activator, 2-6 parts of modified urea-formaldehyde resin, 4-8 parts of reinforcing additive, 2-4 parts of talc, 5-10 parts of dibutyl phthalate, 3-6 parts of pentaerythritol stearate, 3-7 parts of ricinoleate, 2-5 parts of foaming agent, 1-3 parts of softener, 0.5-1.5 parts of vulcanization accelerator and 0.4-0.8 part of anti-aging agent. The foamed rubber sole special rubber material has good wear resistance and mechanical properties and is light in weight, good in elasticity and excellent in aging resistance.

Description

technical field [0001] The invention relates to the technical field of shoemaking, in particular to a rubber material for foaming rubber soles and a preparation method thereof. Background technique [0002] Foam rubber, also known as sponge rubber, has a porous structure and is a composite material composed of rubber and pores. Therefore, it has the characteristics of low density, good elasticity, saving raw materials, heat insulation, sound insulation, good elasticity, and can absorb impact loads. It is widely used in aerospace, automobiles, packaging, construction, shoemaking, sporting goods and other related fields. Due to its unique characteristics, foam rubber is used in shoe sole materials to achieve good results. [0003] When using rubber to make foam, it is usually filled with foaming agent and other additives in the rubber to undergo a chemical decomposition reaction at the vulcanization temperature to decompose gas. There are many types of rubber polymer foam ma...
