Title:
BIO-BASED RUBBER SOLE AND PREPARATION METHOD THEREFOR, AND MOULD
Document Type and Number:
WIPO Patent Application WO/2023/005233
Kind Code:
A1
Abstract:
Disclosed in the present invention are a bio-based rubber sole comprising the following components in parts by weight: 40 parts of bio-based solution polymerised styrene-butadiene rubber, 16-24 parts of bio-based ethylene propylene diene monomer rubber, 38-46 parts of natural rubber, 35-40 parts of white carbon black, 2.1-2.8 parts of silane coupling agent, 0.7-1.1 parts of stearic acid, 0.6-0.9 part of anti-ageing agent, 1.9-2.5 parts of active agent, 3.2-3.8 parts of zinc oxide, 0.7-1.5 parts of polyethylene wax, 1.0-1.8 parts of anti-frosting agent, 0.9-1.4 parts of tackifying resin, 1.2-1.8 parts of vulcanisation accelerator, and 1.9-2.3 parts of insoluble sulphur; in the present application, when the bio-based solution polymerised styrene-butadiene rubber is prepared for polymerisation, carboxylated solution polymerised styrene-butadiene rubber, zinc oxide, stearic acid, and epoxidised soybean oil are mixed in an internal mixer to construct an ester-based cross-linked network structure, having the advantage of no oil separation. In addition, during vulcanisation moulding, ion pairs formed by the zinc ions and carboxyl in the rubber material can be used as strengthening points to increase the degree of crosslinking, enhancing the mechanical performance of the bio-based rubber outsole.
