The invention relates to the technical field of building materials, in particular to an interface agent for a fireproof coating as well as a preparation method and application thereof. The interface agent for the fireproof coating comprises the following components in parts by weight: 180-270 parts of an inorganic adhesive and 80-120 parts of a building emulsion, the inorganic adhesive comprises modified silica sol and potassium silicate; the particle size of the modified silica sol is 10-20 nm. The interface agent for the fireproof material is obtained by compounding the specific inorganic adhesive and the building emulsion, the interlayer binding force between a building structure and a fireproof coating can be remarkably improved, the interface agent is durable, and the problems of coating hollowing, cracking, falling and the like are not prone to occurring in the using process. 本发明涉及建筑材料技术领域，尤其涉及一种防火涂料用界面剂及其制备方法和应用。所述防火涂料用界面剂以重量份计，包括：无机粘接剂180～270份和建筑乳液80～120份；所述无机粘接剂包括改性硅溶胶和硅酸钾；所述改性硅溶胶粒径为10-20nm。本发明通过复配特定
