Long-acting antibacterial agent and preparation method thereof

Abstract

The invention relates to a long-acting antibacterial agent, which comprises the following components: dimethyl sulfone, waterborne polyester polyol, an initiator and a chain extender. The effective component dimethyl sulfone in the non-toxic long-acting antibacterial agent can destroy the living environment of bacteria, effectively reduce the reproduction speed of various bacteria and cannot causethe variation of the bacteria, so that the long-term effective antibacterial effect is achieved; after dimethyl sulfone with a small molecular structure is grafted to a structural unit of water-basedpolyester polyol, the long-acting antibacterial agent can be effectively attached to the surface of an object for a long time to form a layer of tightly cross-linked film, and the attachment durationof effective components is prolonged, so that the actual use effect of the long-acting antibacterial agent is prolonged, the antibacterial frequency is reduced, and a long-term antibacterial effect is achieved.

Description

technical field [0001] The invention relates to a long-acting antibacterial agent and a preparation method thereof. Background technique [0002] Most of the traditional antibacterial agents kill bacteria by using heavy metal ions to destroy the bacterial cell wall structure. The short-term effect of this antibacterial agent is obvious, but as the bacteria mutate and their resistance increases, the effect of using the same type of antibacterial agent is very small and heavy metals seriously affect The health of the human body will cause damage to the human body in many ways. In addition, the existing antibacterial agents basically adopt the method of direct spraying, but because the active ingredients of antibacterial agents are small molecular structures, it is easy to cause rapid loss of active ingredients, and it is impossible to achieve effective adhesion and long-term antibacterial in applicable scenarios. Contents of the invention [0003] The object of the present ...
