[0004] Chinese patent 101643562B reports a high anti-slip rubber for sports shoe soles. It mainly uses high-damping butyl rubber and nitrile rubber to improve the anti-slip effect of the sole. The anti-skid effect of the agent interface and oil stain interface is average; and without chlorinated or brominated butyl rubber, it is difficult to blend with other rubbers such as nitrile, and the overall mechanical properties are poor
[0005] Chinese patent 104277274A reports an oil-resistant anti-slip rubber sole, which uses polar rubber, mainly based on nitrile rubber, epoxy rubber, and brominated butyl rubber; test results show that in glycerin stainless steel The surface test results can pass the American safety shoe SRB standard, but it does not show that it can pass the SRC standard; and a large amount of epoxy rubber is used in the processing process, which is easy to stick to the roller and is not easy to process. In addition, the plasticizer DOP used has been regulated by Europe and other places. Not environmentally friendly and harmful plasticizers

Embodiment 1

[0050] A non-slip rubber outsole consisting of the following raw material components: 60 parts of nitrile rubber (Lanxess krynac 4450 F); 25 parts of integrated rubber (Beijing Yanshan Petrochemical Company 2502); 15 parts of solution-polymerized styrene-butadiene rubber (JEC Asaprene E10) ; Modified liquid polybutadiene rubber (Cray Valley Ricobond) 8 parts; Fumed silica 30 parts; DOS 3 parts; Anti-aging agent (1010) 1.2 parts; Petroleum resin 2 parts; PEG4000 active agent 3 parts; Si-69 2 parts of coupling agent; 1 part of polyethylene wax; 3 parts of zinc oxide; 2.5 parts of sulfur; 1.5 parts of accelerator DM; 1.2 parts of accelerator D.

[0051] The manufacturing process of the anti-skid rubber outsole comprises the following steps:

[0052] Step 1. Accurately weigh nitrile rubber, integrated rubber, solution-polymerized styrene-butadiene rubber, modified liquid polybutadiene rubber, DOS, petroleum resin, antioxidant, PEG2000, Si69, polyethylene wax according to the above...

Embodiment 2

[0056]A non-slip rubber outsole, composed of the following raw material components: 60 parts of nitrile rubber (Lanxess krynac 4560 C); 20 parts of integrated rubber (Beijing Yanshan Petrochemical Company Research Institute 2502); solution-polymerized styrene-butadiene rubber (Lanxess VSL 2438) 20 parts; 7 parts of modified liquid polybutadiene rubber (Cray Valley Ricobond); 20 parts of fumed silica; 1 part of DADI; 1.2 parts of antioxidant (1076); 2.2 parts of petroleum resin; 3.5 parts of PEG4000 active agent; 2 parts of Si-69 coupling agent; 1.2 parts of polyethylene wax; 3.5 parts of zinc oxide; 3 parts of sulfur; 1.5 parts of accelerator DM; 1 part of accelerator NS.

[0057] The manufacturing process of the non-slip rubber outsole in Example 2 is the same as that in Example 1, the difference is that in Step 1 of Example 2, the mixed rubber is derived when the mixing temperature reaches 120°C.

Embodiment 3

[0059] A non-slip rubber outsole, composed of the following raw material components: 60 parts of nitrile rubber (Lanxess krynac 4560 C); 23 parts of integrated rubber (Beijing Yanshan Petrochemical Company Research Institute 2535); solution polystyrene butadiene rubber (Lanxess VSL 2438) 17 parts; 6 parts of modified liquid polybutadiene rubber (Cray Valley Ricobond); 25 parts of fumed silica; 3 parts of DOA; 1.2 parts of antioxidant (SP); 3 parts of petroleum resin; 4 parts of PEG4000 active agent; 2 parts of Si-69 coupling agent; 1.5 parts of polyethylene wax; 4 parts of zinc oxide; 3.5 parts of sulfur; 1 part of accelerator TS; 1.2 parts of accelerator NS.

[0060] The manufacturing process of the non-slip rubber outsole of embodiment 3 is consistent with the manufacturing process of embodiment 1.

Abstract

The invention relates to shoe soles and provides an antiskid rubber outsole which is specially used on surfaces containing surfactants and oil stains and a manufacturing process of the outsole. The antiskid rubber outsole is prepared from nitrile butadiene rubber, integrated rubber, solution polymerized styrene-butadiene rubber, modified liquid polybutadiene rubber, fumed silica, a plasticizer, an anti-aging agent, petroleum resin, a white smoke activator, a silane coupling agent, polyethylene wax, zinc oxide, sulfur, and a vulcanization accelerator. The antiskid rubber outsole has excellent antiskid effect not only on a regular dry or wet surface or a surface containing surfactants, for example, detergents, and an oil stain surface. People can walk safely and stably on the outsoles. The manufacturing process has simple processes and is easy to carry out, and is suitable for large-scale production.

Description

technical field [0001] The invention relates to a shoe sole, in particular to a non-slip rubber outsole and a manufacturing process thereof for use in an environment with extremely slippery interfaces such as surfactants and oil stains. Background technique [0002] With the development of economy and technology, the living standards of consumers are constantly improving, and people pay more and more attention to the quality, performance, safety and comfort of shoes. [0003] At present, domestic shoe soles developed for special places such as kitchens, chemical plants (production of various surfactants, glycerin, polyols, lubricating oil, etc.), car repair shops, oil mills, etc. are uneven, and the physical properties can meet the standards. There are very few. In order to increase the use of shoes in special environments, prevent fall accidents, and ensure the personal safety of users, it is imperative to research and develop anti-skid rubber soles with special interfaces...
