Abstract

The invention discloses an anti-slippery bio-based rubber shoe sole and a preparation method and a mold thereof. The anti-slippery bio-based rubber shoe sole comprises the following components in parts by weight: 50 parts of bio-based solution polymerized styrene-butadiene rubber, 26 to 34 parts of carboxylated nitrile rubber, 16 to 24 parts of epoxidized natural rubber, 35 to 50 parts of white carbon black, 2.1 to 2.8 parts of a silane coupling agent, 1.2 to 1.5 parts of stearic acid, 1.0 to 1.3 parts of an anti-aging agent, 1.9 to 2.5 parts of an active agent, 4 to 6 parts of zinc oxide, 1.2 to 1.5 parts of polyethylene wax, 1.4 to 1.8 parts of an anti-frosting agent, 1.3 to 1.7 parts of tackifying resin, 1.0 to 1.2 parts of a vulcanization accelerator, and 1.1 to 1.5 parts of insoluble sulfur. 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 that oil is not separated out is achieved. Besides, during vulcanization molding, ion pairs formed by zinc ions and carboxyl group in a rubber material can be used as reinforcing points, so a crosslinking degree is improved, and the mechanical properties of a bio-based rubber outsole are improved.

Description

technical field [0001] The invention relates to the technical field of shoe sole preparation, in particular to an anti-wet skid bio-based rubber shoe sole, a preparation method thereof, and a mold. Background technique [0002] At present, in response to the national call, reduce carbon emissions and achieve carbon peaking as soon as possible. In the field of shoemaking, we can do it from three aspects, reducing resource consumption, using waste as resources, and turning harmful into harmless. The rubber and plastics currently used are all obtained from monomers such as ethylene, propylene, and butadiene extracted from petroleum and polymerized, consuming a large amount of petroleum resources. In order to reduce the utilization of petroleum resources, soybean oil and epoxidized soybean oil can be directly added to rubber materials, and then rubber products can be produced through physical blending. However, the aforementioned methods will have small additions, poor compatib...
