Expansion type finishing fireproof coating

The invention relates to the field of composite materials, and particularly provides a novel expansion type finishing fireproof coating. The expansion type finishing fireproof coating is characterized in that a waterborne epoxy-acrylate emulsion is used as a matrix; a monomer expansion flame retardant is used for replacing the traditional mixing type flame retardant; the optimum proportion ratio of components is preferably adopted. The expansion type finishing fireproof coating has the advantages that the flame retardant effect is better, and the heat releasing rate and smoking rate of the acrylate resin are effectively reduced; the mass loss and charring volume are obviously reduced, the total smoke poison releasing parameter of coating is greatly decreased, and the anti-corrosion, fireproof and anti-bacterial properties are excellent.
