Antibacterial color EPDM particle

Abstract

The invention discloses an antibacterial color EPDM particle, and relates to the technical field of plastic tracks. The EPDM particle is composed of following components in parts by weight: 100 partsof EPDM (ethylene propylene diene monomer), 6 parts of zinc oxide, 1 part of carbon black, 40 parts of light calcium carbonate, 25 parts of engine oil, 45 parts of peroxide agent BPMC, 7 parts of antioxidant, 0.2 part of coloring agent, 10 parts of antibacterial shell powder, wherein the antibacterial shell powder is completely made of shells of scallop from Hokkaido. The preparation technology ofthe antibacterial shell powder comprises following steps: placing scallop shells in a high temperature decomposing furnace; burning scallop shells at a high temperature of 1000 DEG C so as to convertcalcium carbonate of shells into calcium oxide; and adding water so as to convert calcium oxide into calcium hydroxide. The antibacterial shell powder has good functions of removing odor, killing bacteria, and preventing oxidation. The provided EPDM particle can resist irradiation of UV rays and strong light, has a good antioxidant performance, a strong antibacterial performance, and a good deodorizing performance, is durable, and has a long service life.

Description

technical field [0001] The invention relates to the technical field of plastic runways, in particular to antibacterial EPDM colored particles. Background technique [0002] Plastic track, also known as all-weather track and field sports track, is composed of polyurethane prepolymer, mixed polyether, waste tire rubber, EPDM rubber particles or PU particles, pigments, additives, fillers and other materials. It has certain elasticity and color. Plastic track has The characteristics of good flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties are conducive to athletes' speed and technique, effectively improving sports performance and reducing the rate of falls. It is internationally recognized as the best all-weather outdoor sports venue. Ping material. The plastic runways of the prior art generally have the following problems: [0003] (1) Since the plastic runway is mostly set up outdoors, it needs to be exposed to sunlight...

AI Technical Summary

Problems solved by technology

[0003] (1) Since the plastic track is mostly set up outdoors, it needs to be exposed to sunlight for a long time, and under the irradiation of sunlight and ultraviolet rays, the plastic particles on the track are prone to fading and aging, and the oxidation resistance is poor.

[0004] (2) The runway does not have the ability to inhibit bacteria and kill bacteria. In addition, due to the harsh environment of the runway, the runway is easily invaded by various bacteria, such as E. coli, E. coli 0-157, Staphylococcus, Salmonella, Morganella, etc. , so that the runway is easily damaged and the service life is greatly reduced

[0005] (3) Due to irregular operation, various runway odors and odors occur frequently, endangering health
