Abstract
The invention discloses a cervical anterior retractor and a preparation method thereof, and relates to the technical field of medical devices, including a retractor and a protective coating, wherein the protective coating comprises the following raw materials in parts by weight: 25-35 parts of modified acrylic emulsion, 20-25 parts of reinforcing filler, 0.5-1.0 parts of thickener, 1.5-2.0 parts of film-forming aid, 15-20 parts of pigment and 20-30 parts of water. The synthesized modified acrylic emulsion is a polyurethane structure and a chitosan structure introduced into polymethyl acrylate to improve the wear resistance, corrosion resistance and antibacterial properties of the cervical anterior retractor. The synthesized reinforcing filler includes nano-calcium carbonate, ester group and ferulic acid structure, which improves the mechanical properties and anti-oxidation aging properties of the protective coating, so that it can better protect the cervical anterior retractor and ensure the good performance and long service life of the cervical anterior retractor.
