Antibacterial agent for producing modified plastic and preparation method thereof

Abstract

The invention discloses an antibacterial agent for producing modified plastics and a preparation method of the antibacterial agent, and aims to solve the problems that in the prior art, an antibacterial agent is poor in antibacterial effect, short in antibacterial time efficiency and single in function, only has the antibacterial effect and does not have the anti-ultraviolet and anti-mildew effects, and when the antibacterial agent is used for producing the modified plastics, the service life of the antibacterial agent is greatly prolonged. And the service life of the plastic cannot be prolonged. The antibacterial agent is prepared from the following components in parts by weight: 10 to 30 parts of zeolite, 10 to 30 parts of glass, 10 to 30 parts of zirconium phosphate, 10 to 30 parts of ceramic, 10 to 30 parts of bentonite, 10 to 20 parts of natural antibacterial compound, 5 to 10 parts of 2-carboxyl-4-methoxybenzophenone, 20 to 35 parts of compound ion solution, 5 to 8 parts of quaternary ammonium salt, 5 to 8 parts of coupling agent and 3 to 5 parts of compound mildew-proof additive. The antibacterial agent prepared by the preparation method of the antibacterial agent is non-toxic and odorless, does not cause harm to human bodies, further improves the antibacterial effect of the antibacterial agent, is long in antibacterial time, has anti-ultraviolet and mildew-proof effects, and can prolong the service life of plastics.

Description

technical field [0001] The invention belongs to the technical field of plastic antibacterial agents, and in particular relates to an antibacterial agent for producing modified plastics and a preparation method thereof. Background technique [0002] Modified plastics refer to plastic products that are processed and modified on the basis of general-purpose plastics and engineering plastics, such as filling, blending, and reinforcement, to improve the performance of flame retardancy, strength, impact resistance, and toughness. Antibacterial agents have excellent antibacterial effects, and have strong inhibitory effects on Gram-negative and positive bacteria, fungi, and molds, so they are widely used in the production of modified plastics. [0003] At present, the invention patent with the patent number CN201210161387.X discloses a preparation method of a plastic antibacterial agent. The preparation method comprises the following steps: 1) immersing muscovite powder in 30% hydro...
