Problems solved by technology

Chinese patent CN102850611A discloses a kind of EVA, styrene-butadiene rubber as the base material, adding glass fiber particles, using a twin-screw extruder to melt and graft to obtain a non-slip sole. Although it has a certain effect on improving the anti-skid performance of the sole, the low-temperature performance of the material It is not good, its anti-skid performance is greatly reduced under low temperature conditions, and the anti-skid effect under wet conditions is not described in this patent; The patent does not elaborate on the anti-skid performance on wet ice, nor does it study the effect of fiber orientation on the anti-skid performance
At the same time, the addition of a large amount of glass fiber will reduce the dry anti-skid performance and wear resistance of the sole

Embodiment 1

[0095] 1) First prepare the rubber compound:

[0096] a) Kneading 80 phr natural rubber and 20 phr butadiene rubber on an open mill using the shear force of the twin-roll mill for 5 minutes to form a smooth roll rubber and then cut the rubber for use.

[0097] b) Relax the roller pitch to 8~10mm, put the rubber covered in step a) into the roller pitch for 1 min, then add 30phr carbon black N220, 5phr engine oil, 1.5phr accelerator DM, 1phr accelerator CZ, 0.5phr accelerator D. Add 1phr antioxidant 4010, 0.5phr antioxidant RD, 0.5phr antioxidant MB, and 1.5phr dispersant FS-12. After the small materials are completely put in, then mix for 3~5min, and then add 2phr of sulfur. Continue mixing for 2 minutes; adjust the roller pitch to 2mm, repeat thinning and triangulation for 3 to 4 times, adjust the roller pitch to 10mm to eject the sheet, cool to room temperature 20℃ and park for 8 hours to obtain the rubber compound;

Abstract

The invention discloses a directionally-arranged short-fiber composite rubber non-slip shoe sole material and a preparation method thereof. The material is made of a rubber compound and a short fiber, and the rubber compound is made of crude rubber, a reinforcing agent and an auxiliary as raw materials. The short fiber in the material has a certain orientation degree and can be combined with various shoe sole materials for molding, and therefore the non-slip performance, particularly the non-slippery performance of a shoe sole on various interfaces (ice surfaces, steel plates, ceramic tiles, glass and the like) is increased.

Description

Technical field [0001] The invention belongs to the field of rubber and shoemaking, and relates to an anti-skid material for oriented short fiber composite rubber sole and a preparation method thereof. Background technique [0002] Anti-slip performance is one of the most basic properties of shoes. Good anti-slip performance of shoes is a necessary condition to ensure the safety of the wearer. Shoes for special occasions and tasks, such as kitchen shoes, outdoor hiking shoes, and shoes for keeping warm in cold winter areas, require outstanding anti-slip properties of the soles. For groups that perform special tasks such as troops, the anti-slip performance of shoes is also very important. Good anti-skid performance can not only ensure the completion of military tactics, but also avoid the danger of soldiers slipping and falling. If a soldier wears continuously slipping military shoes, it may cause the deformation of tactical movements or the deviation of the body's center of gr...
