Step 1), adding the styrene-acrylic emulsion into a stirring kettle for stirring, and then sequentially adding the dispersing agent, the defoaming agent and the film forming agent, and stirring to uniformly disperse all the auxiliary agents in the styrene-acrylic emulsion;
Step 2), adding the filler, the flame retardant, the modified heat insulation particles and the sound insulation particles, and continuously stirring at an increased stirring speed to uniformly disperse the components;
and 3) adding the deionized water and the thickener to adjust the consistency, and then passing through a colloid mill to obtain the flame-retardant heat-preservation sound-insulation coating.
