High-biocompatibility coating liquid and hydrophobic antibacterial gauze dressing

The invention provides a high-biocompatibility coating liquid and a hydrophobic antibacterial gauze dressing, the coating liquid comprises alginate, a silicone oil emulsion and water according to a mass ratio of (0.1-10): (0.1-20): 100, the coating liquid can be subjected to a gel reaction with an ionic liquid, and the ionic liquid comprises at least one of calcium ions, magnesium ions and zinc ions. According to the scheme, the coating liquid and the gauze matched with the coating liquid for use are prepared through specific components and proportions, so that the coating liquid can also be coated or infiltrated and compounded with the gauze, the product is endowed with strong hydrophobicity (water repellency) characteristic through a special coating, pathogenic bacteria and fungi are prevented from being attached to the surface of injured tissues due to hydrophilicity, and the quality of the injured tissues is improved. The wound dressing can be continuously used in the treatment process, anaphylaxis cannot
