Problems solved by technology

Silver ions have the strongest antibacterial properties, but their chemical properties are active, and they are easily converted into brown silver oxide or black elemental silver, so they should not be used in large quantities in white household appliances.
The antibacterial strength of zinc is only 1/1000 of that of silver; copper ions are colored, and a large amount of use will affect the appearance of the product; although metal ions are quick to sterilize, the cost of large amounts of use is high, and the release of heavy metal ions will be har

Abstract

The invention discloses an antibacterial resin composite material. The antibacterial resin composite material comprises 60-85wt% of resin, 5-30wt% of an antibacterial agent, 5-30wt% of a mildew inhibitor, 3-10wt% of a coupling agent and 2-10wt% of a dispersant. The antibacterial resin composite material has antibacterial and antifungal functions through compounding use of the antibacterial agent and the mildew inhibitor; and the addition of the coupling agent and the dispersant solves the problem of poor compatibility of the antibacterial agent and the mildew inhibitor with resin, so the antibacterial resin composite material has stable properties and is difficult to separate. A preparation method of the composite material comprises the following steps: mixing above formula components of the antibacterial resin composite material, and carrying out melt extrusion. The preparation method has the advantages of simple process, low cost, and suitableness for industrial production.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to an antibacterial resin composite material and a preparation method thereof. Background technique [0002] In daily life, quite a number of harmful bacteria exist and multiply on the surface of plastic products, and cause various diseases through contact. Most products need to be packaged with plastic products. The most exposed material before use is plastic packaging materials. As people's awareness of health and environmental protection continues to increase, " Bacteriostasis, sterilization" demand. [0003] The development and research of antibacterial plastics began in the 1980s, and researches in developed countries such as Japan, the United States, and Western Europe have made great progress and are widely used in the packaging industry. The research on antibacterial plastics in my country has only been developed in recent years. The research starting...
