Problems solved by technology

[0002] With people's pursuit of a healthy life, outdoor fitness equipment has gradually become an important tool for fitness and leisure sports. Whether it is in public places such as parks, squares, and residential areas, public fitness equipment will bring greater consumption, but due to public fitness The equipment has been installed outdoors for a long time, exposed to wind, sun and rain for a long time, and the fitness equipment is seriously damaged and aging. In particular, many fitness equipment will be equipped with rubber rings and other rubber accessories on the outside, such as handles and handrails. In the case of natural aging, if the quality is not good, it will cause damage and aging. Once aging, it will cause the rubber ring to break, which has certain safety hazards, and generally the existing rubber materials do not have antibacterial effect. , the function is relatively simple

Abstract

The invention discloses an elastic rubber ring with high antibacterial property and for fitness equipment. The elastic rubber ring is prepared from 55-80 parts of butadiene styrene rubber, 45-60 parts of nitrile rubber, 20-40 parts of modified phenolic resin, 10-20 parts of a styrene-butadiene-styrene block copolymer, 15-20 parts of carbon black, 6-10 parts of polyarylamide fibers, 3-6 parts of nanometer cellulose whiskers, 1-5 parts of a SiC micro-powder wear-resistant agent, 1-2 parts of zinc oxide, 0.5-1.5 parts of a silane coupling agent, 1-2 parts of a vulcanization accelerator 2-5 parts of microcrystalline wax, 1-3 parts of a bacteriostatic agent and 0.5-3 parts of an additive. According to the invention, gamma-aminopropyl silsesquioxane is adopted to modify phenolic resin, and amino-functionalized gamma aminopropyl silsesquioxane reacts with hydroxyl groups of the phenolic resin, so the performance of the phenolic resin is improved, and the phenolic resin has good water resistance, heat resistance and oxidation resistance; and meanwhile, the styrene-butadiene rubber, the nitrile rubber and the styrene-butadiene-styrene block copolymer are jointly used as basic raw materials, so a formed system still has good wear resistance after being irradiated by ultraviolet light; and the bacteriostatic agent is added, so long-term effective bacteriostasis can be realized during use of the elastic rubber ring.
