Title:
ANTI-SLIPPERY BIO-BASED RUBBER SOLE AND PREPARATION METHOD THEREFOR, AND MOLD
Document Type and Number:
WIPO Patent Application WO/2023/005221
Kind Code:
A1
Abstract:
Disclosed in the present invention are an anti-slippery bio-based rubber sole and a preparation method therefor, and a mold. The anti-slippery bio-based rubber sole comprises the following components in parts by weight: 50 parts of bio-based solution polymerized styrene-butadiene rubber, 26-34 parts of carboxylated nitrile rubber, 16-24 parts of epoxidized natural rubber, 35-50 parts of white carbon black, 2.1-2.8 parts of a silane coupling agent, 1.2-1.5 parts of stearic acid, 1.0-1.3 parts of an anti-aging agent, 1.9-2.5 parts of an active agent, 4-6 parts of zinc oxide, 1.2-1.5 parts of polyethylene wax, 1.4-1.8 parts of an anti-frosting agent, 1.3-1.7 parts of a tackifying resin, 1.0-1.2 parts of a vulcanization accelerator and 1.1-1.5 parts of insoluble sulfur. In the present application, when the bio-based solution polymerized styrene-butadiene rubber is prepared and polymerized, carboxylated solution polymerized styrene-butadiene rubber, zinc oxide, stearic acid and epoxidized soybean oil are internally mixed in an internal mixer to construct an ester group cross-linked network structure, and the advantage of having no precipitation of oil is achieved. In addition, during vulcanization molding, ion pairs formed by zinc ions and carboxyl groups in a rubber material can be used as reinforcing points, such that the crosslinking degree is improved, and the mechanical properties of a bio-based rubber outsole are improved.
