Abstract

The invention belongs to the technical field of plastics, and particularly relates to an antibacterial microporous color master batch, which takes polypropylene as a base material, expanded polytetrafluoroethylene as a microporous auxiliary material, carbon black or titanium dioxide as a coloring agent, bamboo charcoal fiber modified porous light calcium carbonate as a filler, and a heat stabilizer, a dispersing agent and an antioxidant as auxiliary materials. According to the invention, the problem of single function of the existing color master batch is solved, the expanded microporous structure of the expanded polytetrafluoroethylene is matched with the porous-microporous structure of the filler to form a microporous structure with a variable structure, and meanwhile, the sterilization and bacteriostasis properties and negative ion characteristics of the bamboo charcoal fiber in the filler are utilized to achieve a good antibacterial effect.

Description

technical field [0001] The invention belongs to the technical field of plastics, and in particular relates to an antibacterial microporous color masterbatch. Background technique [0002] With the continuous development of the plastic industry, plastic coloring is an indispensable link in the process of plastic beautification. Based on the advantages of avoiding environmental pollution and uniform and stable coloring, the masterbatch coloring method has become a widely used plastic coloring method today. This method is made by uniformly attaching super-normal pigments to the resin. [0003] At present, the domestic color masterbatch products have a single structure, incomplete varieties, and are mainly general-purpose products. Therefore, when it is necessary to prepare multi-functional products, it is necessary to add color masterbatches with different functions, thereby consuming a large amount of carrier resin, and by This brings disadvantages such as high consumption of...
