preparation example Construction

[0020] This embodiment also provides a method for preparing the above-mentioned high-adhesion hydrogel fire extinguishing agent, which includes: firstly mixing the water-absorbing resin and the thickener to obtain a mixture, and then adding 10-5000 times the mass of water to the mixture for mixing. Water can be fully mixed with water-absorbent resin and thickener, and can quickly form a high-adhesion hydrogel.

[0021] Preferably, the mass of water is 100-1000 times the mass of the mixture.

[0022] The method of using the above-mentioned high-adhesive water-absorbing gel fire extinguishing agent is as follows: ordinary fire trucks can be used, and 5-100 kg of the mixture can be directly added to the water tank of the fire truck, and a high-adhesive hydrogel can be formed within 10 minutes, which can be sprayed directly on the fire site Extinguishing. This method can replace conventional water series fire extinguishing methods, for example, forest fires, family house fires. ...

Embodiment 1

Abstract

The invention relates to a high-adhesion hydrogel extinguishing agent and a preparation method thereof. The high-adhesion hydrogel extinguishing agent is composed of a thickening agent and a water absorption resin, the weight of the thickening agent accounts for 3% or above of the total mass, and the balance is the water absorption resin; and the water absorption and water retaining property of the water absorption resin and the high-adhesion property of the thickening agent are utilized, a large amount of water can be firmly adhered to the surface of a fire source after the hydrogel extinguishing agent is sprayed to the fire source, a thick water film oxygen-isolating layer can be formed, so that rapid fire extinguishing and cooling are realized. The preparation method of the high-adhesion hydrogel extinguishing agent comprises the following steps that firstly the water absorption resin and the thickening agent are mixed to obtain a mixture, and then water with 10-5000 times mass of the mixture is added into the mixture to mix. The water can be fully mixed with the water absorption resin and the thickening agent, and the high-adhesion hydrogel can be rapidly formed.

Description

technical field [0001] The invention relates to the technical field of fire extinguishing agents, and in particular to a high-adhesion hydrogel fire extinguishing agent and a preparation method thereof. Background technique [0002] In today's society, fire is a common disaster, which poses a huge threat to people's lives and property, and has become a topic of great concern to people and the government. At the same time, with the development of science and technology, more and more fire extinguishing products have been developed. Common fire extinguishing agents include water fire extinguishing agents, dry powder fire extinguishing agents, and foam fire extinguishing agents. However, the current fire extinguishing agent has a relatively single composition, and it is easy to relapse when extinguishing a fire in a large cargo yard, and the fire extinguishing effect is still not good enough. Contents of the invention [0003] The purpose of the present invention is to provi...
