Antimicrobial pbt material and preparation method thereof

Abstract

The invention discloses an antimicrobial pbt material. The antimicrobial pbt material is prepared from, by weight, 3-5 parts of polyvinylpyrrolidone, 70-80 parts of caprolactam, 10-13 parts of attapulgite, 1-1.4 parts of zinc acetate, 2-3 parts of gamma-aminopropyltriethoxysilane, 18-20 parts of oxalic acid, 300-370 parts of polybutylene terephthalate, 6-8 parts of octyl isothiazolinone, 1-2 parts of zinc sulfate, 1.7-2 parts of n-salicylanilide, 10-14 parts of butyl acrylate resin, 1-2 parts of bi-decyl dimethyl ammonium bromide, 0.7-1 part of nickel aminosulfonate and 2-3 parts of sodium diacetate. Polyvinylpyrrolidone, sodium diacetate and the like are further added to the material, and therefore the antimicrobial performance of the finished product is further improved.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to an antibacterial PBT material and a preparation method thereof. Background technique [0002] As a photocatalytic antibacterial agent, ZnO has been widely studied in recent years, and it generates strong oxidative active functional groups under the action of photocatalysis to kill bacteria. It has the advantages of non-toxic, non-irritating, good stability, difficult to decompose under high temperature, long-lasting, low price, rich resources, etc., and has broad application prospects; [0003] At present, the commonly used carriers for loading photocatalysts mainly include carbon nanotubes (CNTs) and activated carbon, mesoporous materials, white carbon black and zeolite, etc. By loading, nanoparticles with uniform size can be obtained, and at the same time, the nano-functional composite materials can be guaranteed. high stability. The nano-photocatalyst / porous mineral compos...

Problems solved by technology

However, during the application process, the polar group of the polyamide 6 material makes it easy to absorb water, resulting in low dry and low temperature impact strength, poor product stability, prone to plastic deformation due to friction, and severe wear. In addition, as a mine The use of engineering plastics does not have antistatic properties and is prone to gas explosions, etc., which affects the dimensional stability, anti-wear and anti-friction properties and electrical properties of its products, which limits its application range;
