Abstract

The invention relates to the technical field of fireproof coatings, in particular to a hydrophobic efficient fireproof coating and a preparation method thereof. The preparation method of the fireproofcoating comprises the following steps: adding a film forming matter, a modifier and aerogel powder into dispersion equipment, carrying out uniform mixing under stirring, performing heating to 80-100DEG C in a stirring state, and keeping the temperature for 2-3 hours; transferring dispersed slurry into a grinding device, performing cooling to 5-10 DEG C, and performing grinding until the finenessof the slurry reaches 35-45 microns; adding pigments and fillers into the ground slurry, and carrying out grinding and dispersing uniformly; transferring the slurry into the dispersion equipment again, performing cooling to 5-10 DEG C, sequentially adding water, a flame retardant and an assistant, and carrying out dispersion; and stopping dispersing, and carrying out sieving and packaging. According to the invention, the film forming matter, the modifier and the aerogel powder are mixed, then heated and dispersed, and then cooled and ground, so the surface of the aerogel powder is coated andmoisture or other small molecular substances are prevented from entering holes of the aerogel powder; and thus, the problems that the aerogel powder is poor in dispersity and prone to losing efficacywhen applied in coatings are solved, the heat conductivity coefficient of the fireproof coating in an earlier stage of heating is obviously reduced, and fireproof time is prolonged.

Description

technical field [0001] The invention relates to the technical field of fireproof coatings, in particular to a hydrophobic high-efficiency fireproof coating and a preparation method thereof. Background technique [0002] Intumescent fire retardant coating is a functional protective coating. In case of fire, it can form a layer of dense carbon layer on the coated surface that is dozens or even hundreds of times the thickness of the paint film, and its thermal conductivity can reach as low as 0.002W. (m·K) -1 , effectively play the role of heat insulation and oxygen insulation to protect the base material, and at the same time has the advantages of low density, easy construction, low cost, and can be used in various complex shapes and surfaces. It is widely used in steel structures, cables, ceilings, walls, tunnels, etc. Fire protection in many places such as aircraft and aircraft. [0003] Intumescent fire retardant coatings are mainly composed of base material emulsion (fil...
