step 1, weighing the following raw materials in parts by weight: 20-30 parts of epoxy resin, 5-12 parts of nano silicon dioxide, 30-50 parts of emulsion, 3-6 parts of graphene, 3-10 parts of bentonite, 3-8 parts of diatom ooze, 5-16 parts of nano microbeads, 3-12 parts of heat-conducting filler, 2-5 parts of auxiliary agent and 40-80 parts of deionized water, wherein the bentonite, the diatom ooze and the heat-conducting filler are ground and then filtered through a screen for later use;
step 2, putting the epoxy resin, the emulsion and the deionized water in the step 1 into a stirrer with the stirring speed of 200-500r/min, and mixing and stirring for 25-40 min;
step 3, regulating the speed of the stirrer to 600-;
and 4, regulating the speed of the stirrer to 800r/min, adding the auxiliary agent in the step 1, uniformly mixing, and stirring for 20-50min to obtain the energy-saving and environment-friendly heating coating.
10. The method as claimed in claim 9, wherein in the step 1, the screen mesh used in the filtration is 500-800 mesh.
