1results about How to "Long antibacterial effect" patented technology

This application relates to an antibacterial hydrocolloid dressing and its preparation method, belonging to the technical field of functional dressings. It comprises the following components in parts by weight: 60-65 parts hot melt adhesive, 5-10 parts polyisobutylene, 25-30 parts CMC, 0.8-1.2 parts CCMC, and 5.5-9 parts antibacterial component. The antibacterial component includes component A and component B. Component A includes at least one of sodium hydrogen phosphite, potassium dihydrogen phosphite, and sodium dihydrogen phosphate; component B includes at least one of zinc chloride and zinc nitrate. This application utilizes the in-situ generation of zinc-based phosphate antibacterial microcrystals during the preparation process of components A and B. It exerts its antibacterial effect through a multi-pathway synergistic mechanism of iron ion chelation to deprive nutrients and zinc ion disruption of cell membranes, effectively reducing the risk of bacterial resistance.
