Title:
STYRENE-BUTADIENE RUBBER BASED NANO COMPOSITE FOAMING MATERIAL WITH HIGH SHRINKAGE STABILITY AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/086249
Kind Code:
A1
Abstract:
Provided are a styrene-butadiene rubber based nano composite foaming material with high shrinkage stability and a preparation method therefor. Styrene-butadiene rubber/ethylene-vinyl acetate, white carbon black, zinc oxide and stearic acid are uniformly and fully mixed in an internal mixer; then a foaming agent, a crosslinking agent, sulphur, an accelerant and paraffin are added to the internal mixer, and mixed to obtain a mixture; organic modified montmorillonoid, organic modified attapulgite and the mixture are added together to the internal mixer, and fully and uniformly mixed, the mixture is pressed into a sheet on an open two-roll mixer, and the sheet is put into a vulcanizing machine and subjected to molding-pressing and cross-linked foaming, and the sheet is discharged and cooled to obtain a styrene-butadiene rubber based foamed sole material. The composite foamed sole material is prepared by blending a binary compounding system of SBR and EVA with inorganic nano particles, and the composite foamed sole material has a better shrinkage ratio, after-shrinkage ratio, density, hardness and compression set resistance.
