Anti-slip agent particle for shoe material and preparation method thereof

Abstract

The invention discloses an anti-slip agent particle for a shoe material in the technical field of sole materials. The anti-slip agent particle for shoe materials comprises the following components inpercentage by weight: 5-25% of C5 petroleum resin, 10-30% of silicon dioxide, 5-25% of rubber oil, 10-40% of polyisobutene, 5-25% of SEBS and 10-50% of EVA resin. The invention also discloses a preparation method of the anti-slip agent particle for the shoe material, which comprises the following steps: weighing the materials; adding C5 petroleum resin, silicon dioxide, rubber oil, SEBS and EVA resin into an internal mixer, primarily mixing, adding polyisobutene by several times, and mixing again; discharging and cooling to obtain a master batch semi-finished product; processing the master batch semi-finished product by a double-screw extruder to form a material strip; granulating the material strips to obtain granules, and screening the granules to obtain anti-slip agent particle; according to the invention, the polyisobutene is prepared into the anti-slip agent particles taking EVA as a carrier, so that the anti-slip agent particles are easy to store and use, the volume and time of materials needing to be treated by directly adding the polyisobutene into the shoe material are reduced, and the anti-slip agent particles are well dispersed in the EVA shoe material and have effectiveanti-slip performance.

Description

technical field [0001] The invention relates to the technical field of shoe sole materials, in particular to anti-slip agent particles for shoe materials and a preparation method thereof. Background technique [0002] There are many kinds of materials for shoe soles, including EVA (ethylene-vinyl acetate copolymer), rubber, thermoplastic elastomers, etc. EVA resin blended foam products have properties such as softness, good elasticity, and chemical corrosion resistance, so they are widely used in various shoe sole materials. The anti-slip performance of the sole directly affects the comfort and safety of the shoes when worn. If the anti-slip performance of the sole is poor, it is easy to slip and fall when walking, which poses a safety hazard. At present, the anti-slip of the sole mainly adopts the design of the sole pattern. Although it has a certain anti-slip effect, the EVA shoe material itself does not have anti-slip performance, and it cannot play a good anti-slip effe...
