Processing method capable of prolonging antibacterial effect of plastic product

Abstract

The invention belongs to the technical field of processing of plastic products and particularly relates to a processing method capable of prolonging the antibacterial effect of a plastic product. The method comprises the following steps: mixing raw materials of the plastic product at the weight ratio and carrying out banburying to obtain a banburyed product; adding polyvinyl alcohol impregnated fiber which is equivalent to 2.5-3.2% of total weight and carrying out heat-preservation stirring under the condition of 50-60 DEG C for 50min; and carrying out banburying at 105-115 DEG C for 5min, pelleting and putting the product into a mold for molding. According to the method, multiple layers of non-soluble antibacterial substances wrap the surface of polyvinyl alcohol fiber by using multiple crosslinking, the antibacterial substances reach the sterilization target under the action of electric field attraction and are good in persistence, the bacteriostatic rate reaches 99.99-100%, the antibacterial substances are used for the plastic products such as home appliances, and the bacteriostatic rate retentivity is relatively good after long-term use or repeated wiping for multiple times. The polyvinyl alcohol impregnated fiber basically does not affect the appearance and the mechanical property of a quality material, and is easy to popularize and use.

[0002] With the development of science and technology, people's research and understanding of environmental microorganisms are constantly improving. While using beneficial microorganisms, they are also alert to the harm of pathogenic microorganisms. Antibacterial plastics are a new type of material with antibacterial and bactericidal properties. Various products made of it have hygienic and self-cleaning functions, and are widely used in chemical, fiber, video, electrical machinery, cement and other industries. Antibacterial agents used in antibacterial plastics can be classified into organic, inorganic and natural, etc., organic Antibacterial agents have strong bactericidal ability and good immediate effect, but they are toxic and safe, will produce microbial resistance, poor chemical stability, and are easy to migrate in plastics. Decomposition fails, so its application range is narrow; inorganic antibacterial agents use the antibacterial and bactericidal effects of metal ions to inhibit the growth and reproduction of bacteria, mainly including the concentration of silver, copper, and zinc. Antibacterial ions are usually carried by certain inorganic substances, such as zeolite, Phosphate, hydroxyapatite, soluble glass, etc., can improve the long-term antibacterial effect through slow release. In the prior art, through ion exchange, multi-layer film and other technologies, a composite aseptic antibacterial with strong antibacterial properties and no discoloration can be obtained. agent, and use antibacterial wood technology to manufacture antibacterial plastics and their products to strengthen the play of antibacterial power. However, the long-term effect of antibacterial plastics in China is low. Therefore, further research on the antibacterial function of plastic products, especially household appliances and daily necessities, is required.
