Abstract

The invention discloses an environment-friendly antibacterial material and a preparation method thereof. The above environment-friendly antibacterial material is prepared from the following compositions in parts by weight: 70-80 parts of polyethylene, 15-17 parts of glass fiber, 5-8 parts of diatomite, 5-7 parts of chlorinated paraffin, 1-3 parts of titanium dioxide fiber, 1-1.5 parts of potassium hexafluorozirconate, 0.5-2 parts of polyvinylpyrrolidone, 0.5-1 part of borax, and 0.5-1 part of benzoyl peroxide. The invention also discloses the preparation method for the environment-friendly antibacterial material.

Description

technical field [0001] The invention belongs to the field of water treatment materials, and in particular relates to an environment-friendly antibacterial material and a preparation method thereof. Background technique [0002] Antibacterial agents used in water treatment can be divided into organic antibacterial agents, inorganic antibacterial agents and natural antibacterial agents. Known inorganic antibacterial agents include apatite, zeolite, glass, zirconium phosphate, silica gel, etc. loaded with silver or copper, etc. Antibacterial metal substances. Compared with organic antibacterial agents, these inorganic antibacterial agents are non-volatile and non-decomposing, so the antibacterial effect lasts longer. However, inorganic antibacterial agents are generally powder antibacterial agents, which are prone to water turbidity and are not easy to recycle. . [0003] Organic antibacterial agents are mostly antibacterial resin compositions, and when used for water treatme...
