Problems solved by technology

[0002] Although the existing rubber is lighter in weight after being foamed, it has poor wear resistance, and can only be used for soles with lower wear resistance requirements, and cannot be used for the production of shoe soles with higher wear resistance requirements. The foam rubber sole has light weight, good elasticity, and good heat insulation and vibration reduction effect, but the foam rubber sole on the market has the defect of poor wear resistance

Abstract

The invention discloses a production method of a foaming rubber sole. The method comprises the steps of: a. weighing the following raw materials by weight: natural rubber, reclaimed rubber, sulfur, activated zinc oxide, engine oil, vulcanization accelerator, vulcanizing agent, phenolic resin and a foaming agent; b. adding the raw materials including the natural rubber, the reclaimed rubber, the phenolic resin, the activated zinc oxide and the engine oil into an internal mixer, then adding the foaming agent into the sizing, continuously mixing, and discharging; c. adding the internally mixed material into an open mill, adding sulfur, the vulcanizing agent and the vulcanization accelerator for vulcanization, standing for 12-24 hours after the sizing mixing, adding the milled sizing into the open mill for hot mixing, and processing the sizing to be of the vulcanization-needed shape. The production method has the advantages that the natural rubber and the reclaimed rubber are mixed in the internal mixer, the mixed material is transferred into the open mill, and sulfur, the vulcanizing agent and the vulcanization agent are added for vulcanization; the reaction temperature is mild, and the reaction time is short; and the sole produced by the method is wear-resistant, aging-resistant and light in weight.

Description

technical field [0001] The invention also relates to a production method of the foamed rubber sole. Background technique [0002] Although the existing rubber is lighter in weight after being foamed, it has poor wear resistance, and can only be used for soles with lower wear resistance requirements, and cannot be used for the production of shoe soles with higher wear resistance requirements. Foam rubber soles have light weight, good elasticity, good heat insulation and vibration damping effect, but the foam rubber soles on the market have the defect of poor wear resistance. Therefore, it is necessary to provide a new technical solution to solve the above problems. Contents of the invention [0003] The object of the present invention is to provide a method for producing foamed rubber soles, the soles produced by the method have good wear resistance. [0004] The technical scheme adopted in the present invention: [0005] A kind of production method of foam rubber sole, ...
