Problems solved by technology

[0008] CN03139107 and CN96106368 also disclose the technology of further manufacturing antibacterial PP by using silver-based antibacterial masterbatch and antibacterial masterbatch prepared by zeolite, silicon dioxide, and adsorbed ammonium salt. These different preparation methods only provide a single antibacterial function
[0009] CN00127954, title of invention "Preparation method of antibacterial and mildew-proof polypropylene silk and empty filter screen" discloses the method of making antibacterial and mildew-proof polypropylene by absorbing nano-silver in the micropores of silicate clay. Research shows that nano-silver has excellent antibacterial properties, but it is difficult to provide materials with excellent anti-mold properties using a single nano-silver

Abstract

The invention relates to a polypropylene master batch with functions of anti-bacteria, and mildew and algae prevention, and a preparation method of the polypropylene master batch. The polypropylene master batch consists of an antimicrobial agent, a mildew inhibitor, an algaecide, a coupling dispersant and a polypropylene resin. By the method provided by the invention, the antibacterial rate of the polypropylene master batch to escherichia coli and staphylococcus aureus is more than or equal to 99 percent; the level of mildew and algae prevention performance is 0 to 1, and the effects of mildew and algae prevention are durable.

Description

【Technical Field】 [0001] The invention belongs to the technical field of polymer materials. More specifically, the present invention relates to a polypropylene masterbatch with antibacterial, anti-mold and anti-algae functions, and also relates to a preparation method of the polypropylene masterbatch. 【Background technique】 [0002] There are a variety of bacteria, fungi and other microorganisms in nature. There are also a large number of algae microorganisms in the water environment. These microorganisms grow and multiply rapidly under suitable environmental conditions. Some of these microorganisms are pathogenic bacteria, and they can also The spread of diseases through contact affects people's health and pollutes the human living environment. Therefore, it is very necessary to develop products with antibacterial, anti-mildew and anti-algae functions. [0003] In the current daily life, polypropylene (PP) plastic products are widely used in kitchen utensils, toilet facilities, ...
