Abstract

The invention discloses an antibacterial wear-resistant flame-resistant plastic, and a preparation method thereof. The antibacterial wear-resistant flame-resistant plastic comprises, by weight, 25 to30 parts of polypropylene, 15 to 20 parts of polycarbonate, 12 to 18 parts of polystyrene, 16 to 22 parts of polyimide, 6 to 10 parts of polyvinylpyrrolidone, 5 to 10 parts of polyvinyl acetate, 7 to12 parts of cellulose acetate fiber, 4 to 10 parts of silica sol, 4 to 10 parts of nanometer bauxite, 5 to 10 parts of shell powder, 3 to 8 parts of sillimanite powder, 4 to 10 parts of glass fiber, 4to 8 parts of hydroxymethyl cellulose, 2 to 4 parts of molybdenum disulfide, 1.8 to 3.2 parts of carbon black, 1.5 to 3 parts of expandable graphite, 3 to 6 parts of nanometer silicon carbide, 3 to 6parts of nanometer titanium dioxide, 2.5 to 4.5 parts of a silane coupling agent, and 2.4 to 4.5 parts of an antiseptic. The antibacterial wear-resistant flame-resistant plastic is excellent in performance, aging resistance, wear resistance, mechanical impact resistance, and flame resistance, and cracking is not easily caused.

Description

technical field [0001] The invention relates to the technical field of plastics, in particular to an antibacterial, wear-resistant and flame-retardant plastic and a preparation method thereof. Background technique [0002] Plastics are made of monomers. The main component of plastics is resin. It is a polymer compound polymerized by addition polymerization or polycondensation reaction, commonly known as plastic or resin. After the general plastic is synthesized, it has poor fluidity, low thermal stability, and is easy to age and decompose. , not resistant to environmental aging. Therefore, in order to improve the above defects, people add heat stabilizers, anti-aging agents, anti-ultraviolet agents to the resin, and add plasticizers to increase its fluidity. The output is suitable for various processing techniques. Special properties, different kinds of plastic varieties. [0003] The plastics in the prior art are easy to age and crack, have low wear resistance, are easy to...
