Problems solved by technology

[0003] However, the mass percent change rate of oil absorption (using 1# standard oil) of ordinary oil-resistant work shoes currently on the market is 6.2-13.6%, the folding resistance of the outsole (continuous flexing without cracks) is 68.7-86.5 times, and the tensile strength is 68.7-86.5 times. 11.5 ~ 14.3Mpa, elongation at break 330 ~ 430%, wear volume (using Akron wear machine) 1.16 ~ 1.34cm3 / 1.61Km, hardness (Shore A) 56 ~ 65 degrees, so the life of this type of work shoes It is generally low, and its average service life is within 4 months. It is mainly reflected in the fact that the soles are not oil-resistant and wear-resistant. Use function

Abstract

The invention discloses oil-proof antistatic mould-pressing outsole rubber compound. The oil-proof antistatic mould-pressing outsole rubber compound is made of, by weight, 70-85 parts of domestic standard rubber 2, 15-30 parts of nitrile butadiene rubber, 2-3 parts of accelerator, 1.6-2.5 parts of sulfur, 2-3 parts of active zinc oxide, 1-1.5 parts of stearic acid, 1.5-2.5 parts of age resister, 50-60 parts of intermediate super abrasion carbon black, 10-20 parts of acetylene black, 6-8 parts of antistatic agent, 20-30 parts of softener, 5-10 parts of tackifier, 0.6 part of release agent and 0.1-0.2 part of peptizer. Further, the invention discloses a preparation method of the oil-proof antistatic mould-pressing outsole rubber compound. Comprehensive performances of the rubber compound are evidently improved, and the average service life of finished products of work shoes made of the rubber compound is longer than 6 months and prolonged by 50% as compared with that of normal products on the market.

Description

technical field [0001] The invention relates to an oil-resistant and antistatic outsole mixed rubber used for making work shoes, and also discloses a preparation method of the mixed rubber. Background technique [0002] In recent years, with the continuous development of the economy, various light fuel oils, solvent oils, and chemical cleaning agents have been used more and more widely, and their quantity and quality have made a qualitative leap. At present, although the working environment for the production, storage, transportation, packaging, sales, and use of the above-mentioned products has been improved, it is still poor overall. With the development of the economy and society, the state and enterprise managers and The safety and labor protection awareness and protection strength of on-site workers have been improved like never before. In recent years, the demand for labor protection products that meet the requirements of the above-mentioned working environment has co...
