Abstract

The invention discloses an antibacterial high-polymer material. The antibacterial high-polymer material comprises raw materials in percentage by mass as follows: 25%-40% of polyethylene, 12%-29% of polyvinyl chloride, 4%-9% of tourmaline anion powder, 5%-11% of sodium hydroxide, 4%-9% of copper oxide, 8%-15% of calcium silicate powder and 8%-20% of polyester fiber. The high-polymer material is prepared from polyethylene and polyvinyl chloride, multiple inorganic antibacterial agents are added to the high-polymer material, the antibacterial effect of the high-polymer material is effectively improved, and the prepared high-polymer material has excellent antibacterial function and higher breaking strength. The dissolution-free inorganic antibacterial agents are adopted, and accordingly, the antibacterial high-polymer material has the characteristics of efficient spectrum, durable effect, high safety, easiness in processing and excellent performance.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to an antibacterial polymer material. Background technique [0002] Polymer materials are divided into rubber, fiber, plastic, polymer adhesive, polymer coating and polymer-based composite materials according to their characteristics. Although the molecular weight of a polymer compound is very large, its chemical composition and structural unit composition are generally relatively simple. It is usually composed of a few elements such as C, H, O, Si, N, etc., and is formed by repeated connections of one or several simple low-molecular compounds (structural units). [0003] Antimicrobials are substances or products that have bacteriostatic and bactericidal properties. The role of antibacterial agents is to affect the growth of microbial hyphae, spore germination, formation of various fruit bodies, cell permeability, mitosis, respiration, cell expansion, disintegration of cell protop...
