preparation example 1

[0017] Preparation Example 1 Preparation of partially crosslinked water-swellable sodium acrylate-acrylic acid copolymer

[0018] Weigh 35.6 g of acrylic acid and put it into a container with stirring, thermometer and ice-water bath. Weigh 14.9 g of 30% sodium hydroxide, add 49.5 g of deionized water to adjust the content of sodium hydroxide to 20%, and transfer it to the dropping funnel. Start stirring, slowly add sodium hydroxide solution dropwise, control the neutralization reaction temperature below 30°C, add crosslinking agent N,N'-methylenebisacrylamide 0.002g, photoinitiator benzoin after completion of neutralization reaction Isopropyl ether 0.015g. Nitrogen for 45 minutes, put into a transparent container, and seal it for later use.

[0019] Put the material liquid in the transparent container under the ultraviolet lamp, adjust the distance so that the light intensity of the ultraviolet lamp is 3000μw / cm 2 , irradiated for 12 hours, the polymerization reaction was c...

[0021] Preparation Example 2 Preparation of partially crosslinked water-swellable potassium acrylate-acrylic acid copolymer

[0022] Weigh 31.7 g of acrylic acid and put it into a container with stirring, thermometer and ice-water bath. Weigh 15.4 g of 30% potassium hydroxide, add 52.9 g of deionized water to make the content of potassium hydroxide 20%, and transfer it to the dropping funnel. Start stirring, slowly add potassium hydroxide solution dropwise, control the neutralization reaction temperature below 30°C, add 0.002g of crosslinking agent hydroxypropyl acrylate and 0.004g of photoinitiator benzoin isopropyl ether after the neutralization reaction is completed. Nitrogen for 45 minutes, put into a transparent container, and seal it for later use.

[0023] Put the material liquid in the transparent container under the ultraviolet lamp, adjust the distance so that the light intensity of the ultraviolet lamp is 5000μw / cm 2 , irradiated for 6h, the polymerization reactio...

Abstract

The invention discloses an environment-friendly biological water-retention fire-extinguishing agent which comprises a part of cross-linking water-swelling acrylate-acrylic acid polymer and microbe. The fire-extinguishing agent can control the decomposing time of a part of cross-linking water-swelling acrylate-acrylic acid polymer and burnt ash according to the quantity of added microbe without toxicity and residues, and catabolite can be used as fertilizer for nourishing soils, and the like. The invention has simple prescription, more environment protection, low cost and can be used for extinguishing in various environments of city buildings, forests, and the like.

Description

technical field [0001] The invention relates to a fire extinguishing agent, more specifically, the invention relates to an environment-friendly biological water-retaining fire extinguishing agent. Background technique [0002] In recent years, with the various decorations of buildings, the increase of electrical products, the increase of electricity consumption, and the warming and drying of the climate, the number of fires has become more and more frequent, and the loss of fires has increased. But the fire extinguishing in the world today basically still adopts untreated tap water and chemical foam to extinguish the fire. Use tap water to extinguish the fire. For a large fire that has already started, the internal temperature of the combustibles is already quite high. Tap water can only temporarily extinguish the flames on the surface of the combustibles. Resurrected. In fact, running water can only prevent the fire from spreading, and buildings that have already caught f...
