Non-slip sheet for shoe sole and preparation method of non-slip sheet

Abstract

The invention relates to a non-slip sheet for a shoe sole and belongs to the technical field of shoe sole materials. The non-slip sheet is prepared from the following components in parts by weight: 3-6 parts of isoprene rubber, 18-25 parts of styrene butadiene rubber, 10-14 parts of butadiene rubber, 10-15 parts of white carbon black, 1-2 parts of white mineral oil, 2-3 parts of basic zinc carbonate, 1-2 parts of an active agent, 0.2-0.4 part of stearic acid, 0.1-0.2 part of an antifogging agent, 0.5-0.7 part of an accelerator, 0.5-0.7 part of a vulcanizing agent, 0.2-0.3 part of glass fibers,and 3-5 part of steel fibers. The invention further relates to a preparation method of the non-slip sheet for the shoe sole. The preparation method comprises the following steps that a mixture A, a mixture B and a mixture C are prepared according to the proportion; the mixture A is put into an internal mixer and evenly mixed for 30 min at the temperature of 100-110 DEG C; the mixture B is added into the internal mixer, the temperature is unchanged, and even mixing is continued for 10 min; and the mixture C is added into the internal mixer, the temperature is increased to 130-150 DEG C, vulcanization is conducted for 2 h, a sizing material poured out from the internal mixer is put into an open mill, and the sizing material is subjected to sheet pressing. The non-slip sheet has the effect of improving the slip resistance of the non-slip sheet.

Description

technical field [0001] The invention relates to the technical field of shoe sole materials, in particular to an anti-slip sheet for shoe soles and a preparation method thereof. Background technique [0002] At present, there will be snow, thin ice, and frozen soil on the outdoor ground in winter. When the soles are in contact with the ground, the water on the snow and ice will form a water film on the surface of the sole, and the water film will isolate the sole from the road. Injuries caused by slipping occur from time to time, and anti-slip sheets are usually pasted on the soles to increase the anti-slip properties of the soles. [0003] The existing Chinese patent application whose authorization announcement number is CN104292554B can be referred to, which discloses a dynamic anti-slip rubber sole on ice and a production method thereof. The composition of the dynamic anti-slip rubber sole on ice includes: natural rubber, neoprene , bromobutyl rubber, nano-silica, plastic...

AI Technical Summary

Problems solved by technology

[0004] There is a large cavity in the center of the hemp fiber, and there are many cracks and holes connected to it in the longitudinal direction, so that the fiber has more capillary channels. The special porous structure of the hemp fiber makes it have a strong adsorption capacity. When walking, the hemp fiber will absorb part of the water. When walking on the ice for a long time, the water absorbed by the hemp fiber will be frozen into ice, so that there will be ice on the surface of the sole, and the friction coefficient between ice and ice Smaller, so the anti-slip performance of the sole decreases
