[0033]Put sodium alginate and water in a No. 1 beaker at a mass ratio of 1:95, stir with a glass rod for 30 minutes, and let it swell for 5 hours. ℃, the rotation speed is 500r / min, heat and stir to dissolve for 60min to obtain sodium alginate solution; put chitosan and water in a No. 2 beaker with a mass ratio of 1:100, stir and mix with a glass rod for 20min, Let stand to swell for 4 hours, then add chitosan enzyme with 0.08 times the mass of chitosan, and place the No. After stirring the enzymolysis for 5 hours, raise the temperature to 95°C, keep warm for 15 minutes to inactivate the enzyme, and wait for natural cooling to room temperature to obtain the modified chitosan liquid; place the aluminum nitride whiskers in a ball mill for ball milling, and pass through a 100-mesh sieve to obtain a refined chitosan solution. Aluminum nitride whiskers, put aluminum nitride whiskers and paraffin wax in a ball mill at a mass ratio of 1:10, mix and ball mill them, and pass through a ...

According to parts by weight, the present invention comprises 20-30 parts of modified chitosan liquid, 10-20 parts of starch, 10-20 parts of bacterial cellulose, 8-10 parts of sodium bicarbonate, 8-10 parts of carbomer, 10-20 parts of water, 8-10 parts of konjac mannose, 8-10 parts of pretreated aluminum nitride whiskers, 8-10 parts of phospholipids, 8-10 parts of protein powder and 8-10 parts of modified gelatin powder Stir and mix for 30-50 minutes in a mixer at a rotational speed of 600-800 r / min to obtain a polymer hydrogel fire extinguishing agent. The polymer hydrogel fire extinguishing agent provided by the invention has excellent fire extinguishing performance.

Description

technical field [0001] The invention discloses a polymer hydrogel fire extinguishing agent, which belongs to the technical field of fire safety. Background technique [0002] Generally speaking, foam fire extinguishing agents and dry powder fire extinguishing agents are mainly used in simple fire extinguishers such as public places, laboratories, factories, etc., to quickly extinguish the fire source at the initial stage of the fire to prevent further expansion of the fire. However, in large-scale fires, most of them use clear water as the fire extinguishing agent; for some airtight environments such as ships and airplanes that cannot be evacuated, water mist fire fighting systems and Halons (Halons) fire fighting systems are generally used to extinguish fires. And other fire extinguishing agents often have some toxicity, even high toxicity and have been greatly restricted. [0003] Water fire extinguishing is an ancient and widely used natural fire extinguishing agent, whi...
