Abstract

The invention relates to the technical field of polymer fire extinguishing materials, particularly to a polymer hydrogel fire extinguishing agent and a preparation method thereof. The polymer hydrogelfire extinguishing agent comprises: 0.1-0.5 wt% of polyacrylate type super absorbent resin and / or an acrylate-acrylamide copolymer, and 0.01-0.5 wt% of inorganic nanoparticles, with the balance beingwater. The inorganic nanoparticles have excellent chemical stability, thermal stability and compatibility. The inorganic nanoparticles are added into the specific super absorbent resin to increase viscosity of the specific super absorbent resin, thus improving the thickness of attachment of the hydrogel fire extinguishing agent, effectively improving fire extinguishing effect of the polymer hydrogel fire extinguishing agent, and allowing the fire extinguishing agent to have good timeliness. Accordingly, the provided fire extinguishing agent has excellent adhesion ability, can have good adhesion ability even on the vertical surface of an object, can cover the surface of the object without falling, and has excellent fire extinguishing effect.

Description

technical field [0001] The invention relates to the technical field of polymer fire extinguishing materials, in particular to a polymer hydrogel fire extinguishing agent and a preparation method thereof. Background technique [0002] So far, water is still the most commonly used fire extinguishing agent, which has the advantages of cheap and easy to obtain, and no pollution to the environment. However, due to the good fluidity of water, most of the water will be lost after being sprayed on the fire site, resulting in waste, and for large-scale fires with a large fire area, rapid fire development, easy reflammation, and difficulty in extinguishing, water extinguishing can only control the spread of the fire. It is difficult to extinguish the fire in time and effectively. [0003] Superabsorbent resin is a three-dimensional network polymer with hydrophilic groups and mild crosslinking. It can absorb a large amount of water and swell and keep the water from flowing out. It has...
