Broad-spectrum antibacterial agent and preparation method thereof

The invention discloses an antibacterial agent and a preparation method thereof. The main antibacterial effective component of garlicin, namely a diallyl sulfide type composition is extracted, then the diallyl sulfide type composition is oxidized to improve water solubility to obtain modified garlicin, and then the modified garlicin and polyhexamethyleneguanidine (PHMG) are subjected to co-blending and modification. Water is used as a solvent, through various addition agents of a compatibilizer, a surfactant and the like, the modified garlicin and the polyhexamethyleneguanidine achieve good mutual dissolving and coblending effects, through synergistic reactions, high-efficiency durable antibacterial effects can be achieved, and the antibacterial agent is suitable for various bacteria and fungi. 本发明公开了一种抗菌剂及其制备方法，提取大蒜素的主要抗菌有效成分二烯丙基硫醚类化合物，对其进行氧化提高其水溶性得到改性大蒜素，再与聚六亚甲基胍(PHMG)共混改性，以水作溶剂，通过增容剂、表面活性剂等各种助剂，使二者达到很好的互容共混效果并通过协同作用来达到更高效、更长久的抗菌效果，并适用于多种细菌真菌。
