Abstract

The invention discloses an anti-microbial rubber plate and a preparation method thereof and relates to the technical field of rubber products. The anti-microbial rubber plate is made from waste rubber powder, silicon rubber, chlorinated rubber, accelerant ZBEC, Shengma fibers, hexamethyldisiloxane, shell powder, opal shale powder, chitosan whisker, organic zinc, nanometer zinc sulfide, nanometer TiO2, east wall soil, sulphur, accelerant OTOS, accelerant PZ, anti-aging agent 4020, anti-aging agent, DTPD, tall oil, and the like. According to the rubber plate provided by the invention, the components including opal shale powder, chitosan whisker, shell powder, east wall soil, Shengma fibers, nanometer zinc sulfide, nanometer TiO2, and the like, are taken as anti-microbial components; the special structures of east wall soil, opal shale powder and shell powder have a certain adsorption effect on bacteria; chitosan whisker and Shengma fibers are matched with nanometer zinc sulfide and nanometer TiO2 with photo-catalytic effect, so that the sterilizing function is strong; the propagation of mould can be effectively avoided; the service life of the rubber plate is greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of rubber products, in particular to an antibacterial rubber sheet and a preparation method thereof. Background technique [0002] Rubber sheet English translation: rubber slab; rubber sheet is a sheet product with a certain thickness and a large area obtained by vulcanizing rubber as the main material (may contain fabric, metal sheet and other reinforcing materials), referred to as rubber sheet. The rubber sheet has high hardness, general physical and mechanical properties, and can work in the air with low pressure and temperature of 20°~+140°C. The rubber sheet is formed by calendering or extruding the mixed rubber, vulcanized by a flat vulcanizing machine or continuously vulcanized by a drum vulcanizing machine. Color: black, gray, green, blue, etc. Widely used in industrial and mining enterprises, transportation departments and housing ground and so on. Used as sealing rubber rings, rubber pads, door ...
