Preparation method of wood surface amphiphobic flame-retardant coating

The invention discloses a wood surface amphiphobic flame-retardant coating and a preparation method thereof, and the wood surface amphiphobic flame-retardant coating comprises the following components in parts by weight: 100 parts of fluorine-silicon organic silicon resin emulsion and 5-60 parts of flame retardant. The flame retardant is a flame-retardant material containing flame-retardant elements of P, N, Si and B. According to the invention, the fluorine-silicon-containing organic silicon resin emulsion and the flame retardant containing P, N, Si and B flame-retardant elements are blended and combined, so that the amphiphobic flame-retardant coating is obtained. In the coating, a fluorine-silicon organic silicon resin emulsion is prepared from a fluorine-containing acrylate monomer, acrylic acid and vinyl siloxane; due to the addition of the flame retardant, not only is the flame-retardant effect achieved, but also the surface of the base material can be roughened, and the hydrophobicity and oleophobicity
