Abstract

The invention belongs to the field of new emergency security materials, particularly relates to a water-based aerogel efficient fire extinguishing agent, and further discloses a preparation method thereof, According to the water-based aerogel efficient fire extinguishing agent, the inorganic aerogel powder, the template agent, the phosphorus-containing flame retardant, the nitrogen-containing flame retardant and the hydrophilic colloid stabilizer are used as raw materials, wherein the efficiency of the fire extinguishing agent is greatly improved by utilizing the ultralow heat conductivity coefficient and ultrahigh adsorption capacity of the inorganic nano porous aerogel; meanwhile, the phosphorus-containing flame retardant and the nitrogen-containing flame retardant are combined to serveas related functional components of the fire extinguishing agent, and the colloid stabilizer and the ion buffer agent are added into the water-based flame retardant, so that the uniformity and the expiration date of the flame retardant are increased, and the fire extinguishing agent has an efficient fire extinguishing function, a good fireproof function and a good flame retardant function; in addition, the fire extinguishing agent also has longer quality-guaranteeing storage life, and the fire extinguishing variety, efficiency and application range are effectively expanded.

Description

technical field [0001] The invention belongs to the field of new emergency security materials, in particular to a water-based airgel high-efficiency fire extinguishing agent, and further discloses its preparation method. Background technique [0002] Serious threat to people's lives and property safety along with the shocking fire of constant report, the performance and the effect of fire extinguishing agent more have aroused people's attention. Fire extinguishing agent refers to the substance that can effectively destroy the combustion conditions and then terminate the combustion. The fire extinguishing agents used by traditional fire extinguishing products on the market mainly include water-based fire extinguishing agents, dry powder fire extinguishing agents and clean gas fire extinguishing agents. [0003] No matter what kind of dosage form the traditional fire extinguishing agent is based on, it usually plays a role in extinguishing the fire from two aspects: one is coo...
