Problems solved by technology

The patents CN 101735495 A, CN 102488348 A, CN 103159993 A, etc. for oil-resistant anti-skid soles that have been published at present all use nitrile rubber as the base rubber. The poor dispersion of black affects its wear resistance, so that the oil resistance and wear resistance cannot be well combined. If the oil resistance is improved and the wear resistance is reduced, it cannot meet the performance requirements of oil resistance and wear resistance at the same time.

Embodiment 1

[0039] In this embodiment, an oil-resistant anti-slip rubber sole consists of the following components by weight:

[0040] 15 parts of nitrile rubber NBR 4975, 65 parts of epoxidized natural rubber, 7 parts of brominated butyl rubber BIIR X2, 13 parts of nano silicon dioxide, 6 parts of plasticizer DOP, 0.9 parts of anti-aging agent 1010, white smoke active agent (Polyethylene glycol PEG-4000) 3.5 parts, silane coupling agent Si 69 2.5 parts, polyethylene wax 3 parts, zinc oxide 3.5 parts, sulfur 2.5 parts, vulcanization accelerator DM 1.5 parts, vulcanization accelerator DBTU 1.0 parts.

[0041] Put the rubber materials other than zinc oxide, sulfur, and vulcanization accelerator into the internal mixer for internal mixing, deglue at 115 degrees, leave at room temperature for 24 hours, and then mix on the double-roller open mill, and add accurately weighed oxide Zinc, sulfur, and vulcanization accelerators are uniformly mixed, and the sheets are uniformly released. Finally, t...

Abstract

The invention relates to a sole, and discloses an oil-proof antiskid rubber sole and a preparation method thereof. The oil-proof antiskid rubber sole comprises: butadiene-acrylonitrile rubber, epoxidized rubber, brominated butyl rubber, nanosilicon dioxide, a plasticizer, an antiaging agent, a white smoke activator, a silane coupling agent, polyethylene wax, zinc oxide, sulfur and a vulcanization accelerant. Compared with the prior art, by adopting the epoxidized rubber as base rubber and combining the butadiene-acrylonitrile rubber with high acrylonitrile content, the sole is excellent in oil-proof property, has good antiskid performance on the oil-polluted interfaces, can keep excellent wear-resistant property while having high oil-proof and antiskid properties, and is wide in application range including places such as ships, petrochemical plants, motor car repair shops, oil plants where oil is accumulated or splashes, the oil-proof antiskid rubber sole can protect people who walk and work on oil dirt areas from difficultly falling down, and the oil-proof antiskid rubber sole is simple in production procedures, easy in industrial production and has good market prospects.

Description

technical field [0001] The invention belongs to the technical field of organic polymer compounds, and in particular relates to an oil-resistant anti-slip rubber sole and a preparation method thereof. Background technique [0002] Now anti-slip performance, as an important safety guarantee for safety shoes and labor insurance shoes, has been included in the scope of safety testing and certification by some countries and regions, such as the international standard ISO 20344: 2011, American ASTM F2913-11, etc., focusing on the detection of oil stains on the interface Anti-slip performance. When there are pollutants such as oil stains on the road surface, the oil stains will not only prevent the contact between the soles and the road surface and the intermolecular bonding, but also because of its strong lubricating effect, the friction coefficient between the soles and the road surface will drop sharply. There is a high probability of slipping and falling when walking on oily r...
