Embodiment 1

[0018] Embodiment 1: Generation and use of the polyacrylic acid (sodium) superabsorbent resin hydroabsorbent gel of invention:

[0019] 1. Synthetic resin polyacrylic acid (sodium) is mixed with 1000 times of water (can be added to the fire truck water tank), and a water-absorbing gel will be formed in half an hour. The gel can be sprayed into the fire with a water gun, and the gel is adsorbed on the burning surface to extinguish the fire.

[0020] 2. Spray polyacrylic acid (sodium) fine powder (about 100 mesh) and 1000 times water ratio from the spray gun to the burning part. Within 15 seconds to 60 seconds, a gel is formed to extinguish the fire.

[0021] 3. Spread polyacrylic acid (sodium) fine powder (about 100 mesh) superabsorbent resin on fire sites (especially grasslands and forests), and then spray water on the resin to make it gel to prevent fire and extinguish fire.

[0022] 4. Mix the synthetic polyacrylic acid (sodium) resin with 5% propylene glycol to form a slu...

Embodiment 2

[0023] Embodiment 2: Generation and use of the inventive starch-grafted acrylic acid (sodium) superabsorbent resin water-absorbent gel:

[0024] 1. Starch-grafted acrylic acid (sodium) is mixed with 1000 times of water to form a water-absorbing gel in half an hour. The gel can be sprayed into the fire with a spray gun, and the gel is adsorbed on the surface of the fire to extinguish the fire.

[0025] 2. Spray starch-grafted acrylic acid (sodium) fine powder (about 100 mesh) and 1000 times water ratio from the spray gun to the fire site. Within 15 seconds to 60 seconds, a gel is formed to extinguish the fire.

[0026] 3. At the fire scene (especially grassland and forest), spread starch-grafted acrylic acid (sodium) fine powder (about 100 mesh) superabsorbent resin, and then spray water on the resin to make it gel to prevent fire and extinguish fire.

[0027] 4. Mix starch-grafted acrylic acid (sodium) resin with 5% propylene glycol to form a slurry, lead a pipe in the spray...

Embodiment 3

[0028] Embodiment 3: Generation and use of the inventive carboxymethylcellulose (CMC) grafted acrylic acid (sodium) superabsorbent resin water-absorbing gel:

[0029] Carboxymethylcellulose (CMC) grafted with acrylic acid (sodium) is mixed with 400 times of water to generate a water-absorbing gel within 1 hour. The gel can be sprayed into the fire with a spray gun, and the gel is adsorbed on the surface of the fire to extinguish the fire.

[0030] At the fire site (especially grasslands and forests), spread carboxymethylcellulose (CMC) grafted acrylic acid (sodium) fine powder (about 100 mesh) superabsorbent resin, and then spray water on the resin to make it gel chemical fire protection and fire suppression.

[0031] Carboxymethylcellulose (CMC) grafted acrylic acid (sodium) resin is mixed with 5% propylene glycol to form a slurry, and a pipe is drawn in the spray gun and sprayed from the spray gun to the fire site together with water to play a role in fire extinguishing.

Abstract

The present invention is water absorbing gel fire extinguishing agent of high-hydroscopicity resin and its application, and aims at raising water-maintaining and fire extinguishing performance and saving water. The present invention features that high-hydroscopicity resin comprising synthetic resin, starch and fiber as the kernel components is mixed with water to form the fire extinguishing agent, which is used via traditional fire nozzle. When used, the high-hydroscopicity resin may be mixed with great amount of water for half an hour to create water absorbed gel sprayed with fire nozzle to the fire; or the high-hydroscopicity resin powder may be mixed with great amount of water and sprayed to the fire to form fire extinguishing gel in 15-60 sec; or the high-hydroscopicity resin may be mixed with some organic solvent and sprayed together with water to the fire; or fine high-hydroscopicity resin powder may be spread and water is sprayed to form fire extinguishing gel.

Description

technical field [0001] The invention belongs to the technical field of fire protection, and relates to a novel fire extinguishing agent and its application. Background technique [0002] Fire is a major disaster in today's society. Fires occur almost every day in the country, often causing huge losses of life and property. How to extinguish fires quickly, save lives as much as possible, and reduce economic losses has become a matter of great concern to the people and the government. Current fire extinguishing is especially to the fire extinguishing of large-scale fire scene, adopts water gun to carry out high-pressure high-speed spray water fire extinguishing usually. However, due to the ferocity of the fire and the extremely high temperature, the water will be evaporated immediately when it reaches the fire site, and the water retention capacity is poor, so it is difficult to efficiently complete the important task of extinguishing the fire.
