The invention relates to the field of coatings, in particular to the field of C09D131, and more particularly relates to a high-strength fireproof coating priming emulsion, a preparation method thereof and a fireproof coating. The priming emulsion is prepared from the following raw materials in parts by mass: 40 to 50 parts of ethylene-vinyl acetate emulsion, 30 to 40 parts of acrylate emulsion, 1.4 to 1.8 parts of consistency regulator and 10 to 30 parts of water, the priming emulsion has relatively low volatilization amount and moderate pH value, and when the priming emulsion is applied to the fireproof coating, the fireproof coating can be ensured to have excellent adhesive property; meanwhile, the damp-heat resistance test and the freeze-thaw resistance test of the fireproof coating are qualified, and the application range is wide. 本发明涂料领域，尤其涉及C09D131领域，更具体的涉及一种高强度防火涂料打底乳液及其制备方法和防火涂料。打底乳液的制备原料按照质量份数计包括：40-50份乙烯-醋酸乙烯乳液，30-40份丙烯酸酯乳液，1.4-1.8份稠度调节剂，10-30份水，该打底乳液具有较低的挥发量和适中的pH值，应用在防火涂料中可以保证防火涂料具有优异的粘接性能，同时防火涂料的
