Abstract

The invention relates to an oil-resistant anti-static rubber shoe sole which is prepared from the following raw materials in parts by weight: 840-960 parts of NBR / PVC, 40-50 parts of magnesium oxide, 12-24 parts of stearic acid, 12-16 parts of an antiager, 280-320 parts of white carbon black, 18-22 parts of a coupling agent, 170-190 parts of light calcium carbonate, 110-130 parts of dioctyl-phthalate, 8-10 parts of polyethylene glycol, 12-17 parts of sulphur and 14-30 parts of an accelerant. Rubber-plastic alloy (NBR / PVC=70 / 30) is used as a main rubber material, the rubber-plastic alloy has excellent oil resistance and ageing resistance, heat conduction / conductivity is excellent due to that the NBR / PVC is a polarity high polymer material simultaneously, static electricity generated by a human body during wearing is released through a show outsole, and then an excellent anti-static effect is realized. For meeting environmental protection needs, conventional carbon black is replaced by the white carbon black in the formula to reinforce a sizing material, the coupling agent is added in the formula to improve the bonding strength of the white carbon black and the NBR / PVC simultaneously, and the polyethylene glycol is used to adjust the acid-base property of rubber compound to meet the normal vulcanizing process.

Description

technical field [0001] The invention relates to a rubber sole, in particular to an oil-resistant and antistatic rubber sole, and a preparation method for the oil-resistant and antistatic rubber sole. Background technique [0002] Rubber soles are generally made of natural rubber as a raw material, after mastication, plus other ingredients for mixing and refining to make rubber soles. Since what is used is natural rubber, plastication is required, which consumes manpower and material resources and increases the cost. On the other hand, it is difficult to control the acidity and alkalinity of the mixed rubber during the preparation process with carbon black for rubber reinforcement, and it is difficult to meet the subsequent vulcanization process. Contents of the invention [0003] The object of the present invention is just to overcome above-mentioned deficiency and provide a kind of oil resistance, antistatic rubber sole and preparation method thereof. [0004] The purpo...
