Title:
HYDROPHOBIC EFFICIENT FIRE-RETARDANT COATING AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/078117
Kind Code:
A1
Abstract:
A hydrophobic efficient fire-retardant coating and a preparation method therefor, relating to the technical field of fire-retardant coatings. The preparation method for the fire-retardant coating comprises: adding a film forming matter, a modifier and aerogel powder into a dispersion device, carrying out uniform mixing under stirring, heating to 80-100ºC in a stirring state, and keeping the temperature for 2-3 hours; transferring dispersed slurry into a grinding device, cooling to 5-10ºC, and grinding until the fineness of the slurry reaches 35-45 μm; adding pigments and fillers into the ground slurry, and carrying out grinding and dispersing uniformly; transferring the slurry into the dispersion device again, cooling to 5-10ºC, sequentially adding water, a flame retardant and an assistant, and carrying out dispersion; and stopping dispersing, and carrying out sieving and packaging. 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 and moisture or other small molecular substances are prevented from entering aerogel powder pores; and thus, the problems that the aerogel powder is poor in dispersity and prone to losing efficacy when applied in coatings are solved, the heat conductivity coefficient of the fire-retardant coating in an earlier stage of heating is obviously reduced, and fire-retardant period is prolonged.
