Abstract

The invention belongs to the field of polymer materials, and discloses an anti-bacterial polymer material. The anti-bacterial polymer material comprises the following components in parts by weight: 29-37 parts of polyethylene, 17-26 parts of polyisobutene, 12-19 parts of a polyester fiber, 5-11 parts of 1-amylene, 3-9 parts of ammonium dihydrogen carbonate, 4-8 parts of zinc oxide and 5-7 parts of calcium silicate powder. The preparation method comprises the following steps: (1) grinding calcium silicate until the granularity is 300-400 meshes for later use; (2) taking polyethylene, polyisobutene, the polyester fiber and 1-amylene according to the weight, heating, and then uniformly stirring; (3) then adding ammonium dihydrogen carbonate, zinc oxide and the calcium silicate powder according to the weight, heating, and then uniformly stirring; and (4) adding uniformly-stirred raw materials into a double-screw extruder, and performing extrusion to obtain the anti-bacterial polymer material disclosed by the invention.

Description

technical field [0001] The invention belongs to the field of polymer materials, and relates to a polymer material and a preparation method thereof, in particular to an antibacterial polymer material and a preparation method thereof. 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). 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 bo...
