Problems solved by technology

[0003] Although many major breakthroughs have been made in the research and application of antibacterial resins at home and abroad, they all come down to the compounding and integration of antibacterial materials and resins. However, so far, no resins with clear antibacterial effects have been found in the world.

Abstract

The invention is a production process of a novel resin, which is characterized in that it is prepared through condensation reaction of acrolein and vinyl ethyl ether. The new resin is composed of a high polymer of heteropolyene ether aldehyde and a certain amount of EOHP. It is a kind of pyranyl ether antibacterial body. They are the only ones in the world that only contain carbon (C) hydrogen (H) oxygen (O ) three-element and halogen-free antibacterial functional group, which can be biodegraded in the environment. When the surface of the new resin is in contact with the air, microorganisms adhere and gather to form a so-called biofilm. The antibacterial alkyl ether on the resin layer can penetrate the 1.8mm biofilm cell wall within 20 minutes and combine with amino acids, making it impossible for microorganisms to absorb nutrients and eliminate waste. The novel resin obtained by the production process of the invention has long-acting and durable antibacterial function. The antibacterial group of the new resin has a very fast bactericidal effect, and the bactericidal rate can reach more than 99% in an average of 2-5 hours.

Description

technical field [0001] The invention relates to a novel resin production process with antibacterial and antifungal properties. Background technique [0002] In the past thirty years, people have conducted a lot of research on the antibacterial properties of resins. Many major breakthroughs have been made in the characteristics, mechanism, and modification of antibacterial resins. The current research and application are developing in two aspects: one is to add a dissolving fungicide to the base material of the resin. Produce effective antibacterial ingredients, so as to achieve antibacterial effect. Among them, inorganic antibacterial materials such as silver series ions, photocatalysts (nano TiO 2 ) and so on have been rapidly developed and increasingly widely used. However, the dissolution of antibacterial factors is a simple diffusion, and its kinetic factors are difficult to control. When the antibacterial agent is released in large quantities in the early stage, the...
