Preparation method of antibacterial polyester material

Abstract

The invention discloses a preparation method of an antibacterial polyester material. The preparation method of the antibacterial polyester material comprises the following concrete steps: 1) preparing a disperse system composed of nano cuprous oxide particles and polyalcohol; 2) adding polyacid into the disperse system prepared in the step (1), so as to prepare a polyester composite melt containing the nano cuprous oxide particles; 3) carrying out extruding, bracing, water cooling and pelletizing on the polyester composite melt containing the cuprous oxide particles, thus an antibacterial polyester material is obtained. The prepared antibacterial polyester material has the advantage of good, lasting and stable antibacterial effect.

Description

technical field

[0001] The invention relates to the technical field of antibacterial materials, in particular to a preparation method of antibacterial polyester materials. Background technique

[0002] Antibacterial agents refer to a class of functional materials that can kill or inhibit the growth of microorganisms. There are three main types: organic antibacterial agents, inorganic antibacterial agents, and natural biological antibacterial agents. Inorganic antibacterial agents are widely used due to their advantages of high temperature resistance and not easy to decompose. At present, the most widely used inorganic antibacterial agents are simple silver and silver salts containing silver ions. In addition to silver-containing antibacterial agents, more and more attention has been paid to copper-based antibacterial materials, such as copper oxide, cuprous oxide, cuprous chloride, copper sulfate, etc., and copper oxide and cuprous oxide are more widely used.
