Abstract

The invention belongs to the technical field of rubber and plastic products. The invention provides a mould-proof antibacterial rubber and plastic product. The product comprises, by mass, 15-20 partsof nitrile rubber, 8-10 parts of polyvinyl chloride resin, 7-9 parts of a foaming agent, 20-30 parts of a flame retardant, 6-8 parts of operating oil, 1-2 parts of an antibacterial agent, 0.3-0.5 partof an active agent, 0.1-0.3 part of stearic acid, 3-5 parts of protective wax, 3-5 parts of an accelerant, 0.5-0.8 part of a vulcanizing agent and 2-3 parts of carbon black. The nitrile rubber, the polyvinyl chloride resin, the foaming agent, the flame retardant, the carbon black, the operating oil, the antibacterial agent, the protective wax, the active agent and the stearic acid are blended through an internal mixer, discharged, remixed and stored for 22-26 h; then the vulcanizing agent and the accelerant are added for mixing, extrusion molding and vulcanization foaming are conducted, and the mildew-proof and antibacterial rubber and plastic product is obtained. By means of the technical scheme, the problems that in the prior art, rubber products are prone to mildewing, and normal use is affected are solved.

Description

technical field [0001] The invention belongs to the technical field of rubber and plastic products, and relates to a mold-proof and antibacterial rubber and plastic product and a preparation method thereof. Background technique [0002] The rubber industry is an important part of my country's chemical industry. The basic raw materials of the rubber industry are natural rubber and synthetic rubber. In order to manufacture rubber products that meet the actual performance requirements and improve the processing performance, various chemical processing aids must be added. At present, the general production of rubber and plastic products uses nitrile rubber and polyvinyl chloride resin as the main material, adding other auxiliary materials to blend at high temperature, and then adding vulcanizing agent and foaming agent to undergo vulcanization and foaming, and finally realize the preparation of rubber and plastic products, but the production High-quality rubber and plastic produ...
