Aerogel fireproof coating

Abstract

The invention discloses an aerogel fireproof coating, and belongs to the technical field of building materials. The aerogel fireproof coating is prepared according to the following steps: stirring andmixing hollow glass beads with hydrofluoric acid, conducting filtering and washing to obtain pretreated hollow glass beads, mixing the pretreated hollow glass beads, bacillus pasturii, urea and water, conducting fermentation, then adding a calcium nitrate solution, conducting stirring and mixing, and conducting filtering, washing, drying and high-temperature treatment to obtain a modified thermalinsulation filler; and stirring and mixing the modified thermal insulation filler, a flame retardant, a binder, a plasticizer, a stabilizer, a modified additive, a moisture-proof agent, water, a surfactant, wood chips, an organic acid and unsaturated polyester resin to obtain the aerogel fireproof coating. The aerogel fireproof coating prepared by the technical scheme has the characteristics of excellent heat insulation performance and fire resistance.

Description

Technical field [0001] The invention discloses an aerogel fireproof coating, which belongs to the technical field of building materials. Background technique [0002] Fire-retardant coating is a kind of measure-type fire-retardant material, which has been widely used and has achieved good fire-proof effect. Fire-retardant coatings are often used to coat the surface of combustible substrates, which can reduce the flammability of the surface of the coated material, prevent the rapid spread of fire, or are applied to the surface of structural materials to increase the fire resistance limit of components, but also There are certain drawbacks. For example, inorganic fireproof materials based on sodium silicate have water resistance problems, and non-intumescent fireproof coatings based on cement-based materials have problems such as thicker coatings, low bonding strength, and easy peeling off in the later stage. The material cost is high, and has a certain degree of toxicity, which ...
