Abstract

The invention discloses a composite flame-retardant heat-insulation cooling material and thixotropic hydrogel thereof, the material is prepared from super absorbent resin, water-soluble metal salt, water-soluble polysaccharide hydrosol, water-insoluble inorganic particles and a modifier through a composite process, wherein the material and water are mixed and stirred according to a mass ratio of 1:80-250, and standing treatment is carried out for 13 minutes to form the hydrogel. The hydrogel is excellent in thermal protection performance, flexible in texture, high in adhesiveness, non-toxic, non-irritant, green, environment-friendly, safe and reliable.

Description

technical field [0001] The invention relates to a heat-insulating protective material, in particular to a composite flame-retardant heat-insulating and cooling material and a thixotropic hydrogel thereof, belonging to the technical field of heat-insulating materials. Background technique [0002] There are inevitably potential sources of thermal hazards in battlefields, fire sites, petrochemicals, coal metallurgy and many other fields, which may be in the form of combustion, explosion, high-temperature gas, molten metal droplets, water vapor, high-temperature liquid splashes, etc. Super absorbent resin has strong water absorption and water retention, low price, and is environmentally friendly. At present, several patents have applied it to water-based fire extinguishing agents. It is a fire-extinguishing mechanism that cools down through a large amount of water evaporation and isolates oxygen and combustibles. The fire-extinguishing effect It is very significant, and the rap...
