Abstract

The invention discloses a foamed rubber shoe sole production formula and a preparation method thereof. A foamed rubber shoe sole consists of the following components in percentage by weight: 40-60 percent of natural rubber, 0.5-1.5 percent of sulfur, 1-3 percent of zinc oxide, 20-40 percent of silicon dioxide, 1-3 percent of recycled rubber powder, 1-3 percent of stearic acid, 0.5-3 percent of vulcanization accelerator, 10-20 percent of engine oil, 0.1-0.5 percent of toner powder and 4-10 percent of foaming agent, wherein the total content of the components is 100 percent. The foamed rubber shoe sole produced with the method has the characteristics of wearing resistance, water resistance, aging resistance, low production cost, light weight, high damping performance and high comfort.

Description

technical field [0001] The invention belongs to the technical field of rubber processing, and relates to a production formula of foamed rubber soles and a preparation method thereof. Background technique [0002] The foam rubber sole has the advantages of light weight, good elasticity, heat insulation and vibration damping and good comfort. However, the foamed rubber soles currently on the market have the disadvantages of poor wear resistance, easy cracking, aging and high production costs. Contents of the invention [0003] The object of the present invention is to provide a production formula and a preparation method of a foamed rubber sole with low production cost, good wear resistance, non-cracking and aging resistance. [0004] In order to achieve the above object, a kind of foam rubber sole of the present invention is made up of natural rubber, sulfur, zinc oxide, silicon dioxide, reclaimed rubber powder, stearic acid, vulcanization accelerator, machine oil, toner...
