Problems solved by technology

However, polymer water-absorbing resins are usually prepared from acrylate as a monomer. The degradation performance of polyacrylate is poor, and the gel after absorbing water and swelling exists in the ecological environment for a long time, which is easy to cause secondary pollution to the environment.

Embodiment 1

[0036] A naturally degradable polymer gel water-based fire extinguishing agent, comprising 50 parts of lignocellulose-modified SA resin and 56 parts of polyacrylamide;

[0037] The modified SA resin is a benzoin-SA compound, and its preparation method is:

[0038] 1) Put 45 parts of SA, 3 parts of diluent and 8 parts of propylene glycol solution into the mixer, and stir at 120°C until the acid value of the mixed solution is 18;

[0039] 2) Add 3 parts of benzoin to the above mixed solution, and continue stirring for 1 hour;

[0040] 3) Put the mixed solution in step 2) into a screw extruder for extrusion molding, and then cool to room temperature to obtain a benzoin-SA compound.

[0041] The preparation method of lignocellulose modified SA resin is:

[0042] 1) Dissolution of lignocellulose: according to the weight and number ratio of benzoin-SA compound and lignocellulose is 1:0.15, add weight parts of lignocellulose until the mass fraction is 5% sodium hydroxide solution a...

Embodiment 2

[0047] A kind of naturally degradable polymer gel water system fire extinguishing agent, including 40 parts of lignocellulose modified SA resin, 46 parts of polyacrylamide;

[0048] The modified SA resin is a benzoin-SA compound, and its preparation method is the same as in Example 1;

[0049] The difference between the preparation method of lignocellulose-modified SA resin and Example 1 is that the ratio of benzoin-SA compound to lignocellulose by weight is 1:0.15.

Embodiment 3

[0051] A kind of naturally degradable polymer gel water system fire extinguishing agent, including 60 parts of lignocellulose modified SA resin, 72 parts of polyacrylamide;

[0052] The modified SA resin is a benzoin-SA compound, and its preparation method is the same as in Example 1;

[0053] The difference between the preparation method of lignocellulose-modified SA resin and Example 1 is that the ratio of benzoin-SA compound to lignocellulose by weight is 1:0.2.

Abstract

The invention relates to the technical field of fire extinguishing agents, in particular to a naturally degradable polymer gel water-based fire extinguishing agent, comprising the following components by weight: 40-60 parts of lignocellulose modified SA resin, 40-60 parts of polyacrylamide 72 parts; wherein, the preparation method of lignocellulose modified SA resin comprises the following steps: 1) dissolving lignocellulose; 2) extracting lignocellulose; 3) blending lignocellulose and resin; 4) extrusion : Obtained lignocellulose modified SA resin. The naturally degradable polymer gel water-based fire extinguishing agent provided by the present invention has the effect of being naturally degradable.

Description

technical field [0001] The invention relates to the technical field of fire extinguishing agents, in particular to a naturally degradable polymer gel water-based fire extinguishing agent. Background technique [0002] With the rapid development of my country's economic construction, the types of fires are becoming more and more diverse, and the fire situation is becoming more and more serious. Therefore, the application and research of fire extinguishing agents are becoming more and more important. Water, being a nonflammable liquid, is the most abundant natural fire extinguishing agent and the most widely used. However, water is easy to flow, and the residence time of spraying into the combustion zone is very short, and most of it is lost. In the actual fire extinguishing process, only a small part has played a role, the waste rate is high, and the anti-reburning performance is poor. [0003] The polymer gel water-based fire extinguishing agent is prepared by mixing the ra...
