Abstract

The invention discloses an antibacterial composition, a preparation method and application thereof, an antibacterial chopping board and a manufacturing method of the antibacterial chopping board. Wherein the antibacterial composition comprises 64-89% of resin, 19-40% of glass fiber and 1.1-2.6% of an antibacterial agent, and the antibacterial agent is one or more of a zirconium phosphate silver-loaded antibacterial agent, a zirconium phosphate zinc-loaded antibacterial agent and a zirconium phosphate copper-loaded antibacterial agent; the resin is styrene resin and / or melamine resin. The antibacterial composition has efficient antibacterial performance, and an excellent antibacterial effect can be achieved by adding a small amount of the antibacterial composition; after the antibacterial composition is used for preparing the chopping board, the structural performance of the chopping board can be improved, and the chopping board is higher in strength, wear-resistant, not easy to generate scratches, seamless and capable of avoiding generation of a bacterium breeding environment.

Description

technical field [0001] The invention relates to an antibacterial composition, a preparation method and application thereof, an antibacterial cutting board and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, people's requirements for clothing, food and housing are also increasing, such as the demand for antibacterial and antivirus, especially kitchen supplies (such as cutting boards, chopsticks, etc.) that are closely related to human health, and more attention is paid to their antibacterial properties. performance. Harmful viruses, bacteria, fungi and other microorganisms in nature have long been the main cause of human infectious diseases. And people's daily work and daily necessities in daily life will be attached to various microorganisms such as Escherichia coli, Staphylococcus aureus, Bacillus subtilis, Pseudomonas aeruginosa, Aspergillus flavus, etc. due to frequent use, which can cause dysentery, food poi...
