Antibacterial and mildew resistant PVC soft colloidal particle and preparation method thereof

Abstract

The invention discloses an antibacterial and mildew resistant PVC soft colloidal particle and a preparation method thereof. An antibacterial and mildew resistant component used in the colloidal particle is an inorganic anti-bacterial and mildew resistant agent treated by a special process. After treated by the special process, the inorganic anti-bacterial and mildew resistant agent is not prone tomigration, low in use addition, stable in color, safe in use, high in antibacterial effect, broad-spectrum antibacterial, non-toxic and non-irritating. The preparation method of the antibacterial andmildew resistant PVC soft colloidal particle can effective improve the dispersion effect of nano inorganic powder in a whole mixture and can effectively improve the antibacterial and mildew resistantefficiency. In addition, the prepared PVC soft colloidal particle has good thermal stability and migration resistance and is an ideal antibacterial and mildew resistant sealing and lining material.

Description

Technical field [0001] The invention relates to a PVC soft rubber particle and a preparation method thereof, in particular to an antibacterial and mold-proof PVC soft rubber particle and a preparation method thereof, and belongs to the technical field of multifunctional composite polymer materials and their processing. Background technique [0002] The refrigerator door sealing strip is a refrigerator accessory used to seal between the refrigerator door and the box. Its function is to ensure the fresh-keeping effect of the refrigerator and at the same time extend the service life of the refrigerator. Because refrigerators are often used to store food, there are many daily contacts, and because of the refrigeration of the compressor, the surrounding area of ​​the refrigerator is generally relatively humid, which can easily breed bacteria, molds and other harmful microorganisms, thereby threatening human health. Similarly, because the inner lining of the washing machine is exposed ...

AI Technical Summary

Problems solved by technology

The resin compositions containing antibacterial and antifungal agents disclosed in the prior art usually contain more problems, such as the addition of antibacterial agents and antifungal agents in some resin compositions. Such a large amount of antibacterial agents and antifungal agents The addition of additives will definitely affect other properties of the polymer such as mechanical properties, thermal properties, hardness, etc., and will affect the processing of materials and products; there are also antibacterial compositions, such as antibacterial plastics and refrigerator door seals, etc., whose antibacterial The main component is silver ions supported by inorganic nanoparticles, but its application is limited due to the problem of discoloration of silver ions during processing
