Abstract

The invention relates to a preparation method of a novel antibacterial agent. A certain amount of yttria, a certain amount of deionized water and a certain amount of nitric acid are weighed, and Y(NO3)3*6H2O is formed; a certain amount of nonylphenol polyoxyethylene ether, a certain amount of glycerin, a certain amount of cycloheptane and a certain amount of Y(NO3)3*6H2O are weighed, and a solution A is formed; a certain amount of nonylphenol polyoxyethylene ether, a certain amount of glycerin, a certain amount of cycloheptane, a certain amount of 5- chloro-7-hydroxyquinoline and a certain amount of sodium o-hydroxyphenylacetate are weighed, and a solution B is formed; a certain amount of the solution A, a certain amount of the solution B and a certain amount of tetraethoxysilane are weighed, and the antibacterial agent is obtained. According to the technical scheme, the antibacterial performance of a polyolefin composite is improved through addition of the specially-made antibacterialagent, and the antibacterial agent has the great promotional value.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, in particular to a preparation method of a novel antibacterial agent. Background technique [0002] In order to effectively prevent the pollution and infringement of bacteria and other microorganisms, the use of antibacterial materials has become an urgent need and choice. Antibacterial agents are the most critical part of antibacterial materials in their antibacterial effect. This technical solution innovatively synthesizes a new type of antibacterial agent, which can well improve the antibacterial performance of polyolefin composite materials. This antibacterial agent has not been reported so far, which has very important practical significance for expanding the types and applications of antibacterial agents. Contents of the invention [0003] The purpose of the present invention is to provide a preparation method of a novel antibacterial agent, and the prepared antibacterial agent...
