The invention belongs to the technical field of fire extinguishing agents, and particularly relates to a novel high-molecular water-based fire extinguishing gel, and a preparation method and application thereof.
Technical Field
The gel fire prevention and extinguishing technology is applied earlier in China, and gel materials are developed from inorganic gel materials to organic polymer materials. The silicic acid gel is used as a mature inorganic gel material and has a good effect, but harmful gases harmful to human health can be generated in the specific use process; the gel material partially taking the electrolyte as the coagulant has strict requirements on water quality, is not suitable for the water environment under a mine, has poor stability, is easy to age and has long gelling time.
The super absorbent resin is a three-dimensional network polymer which has hydrophilic groups and is slightly crosslinked, can absorb a large amount of water, swell and keep the water not to flow out, and has the advantages of high water absorption rate, strong water retention performance and the like. The polymer hydrogel of polyacrylic acid super absorbent resin has been widely used in the field of fire extinguishing. However, hydrogel fire extinguishing agents based on polyacrylic superabsorbents also have some disadvantages. Because the super absorbent resin has low self-gravity and self-adhesive capacity, the polyacrylic acid super absorbent resin is difficult to adhere to vertical wall surfaces, surfaces of wooden furniture and surfaces containing stainless steel (such as the surfaces of oil tank trucks), and thus cannot be effectively covered on objects to achieve the effects of fire extinguishing and protection. Therefore, the search for a novel polymer gel with good gel performance, high temperature resistance, strong fire extinguishing performance, strong adhesive capacity and lasting fire extinguishing capacity is a hot point of the current domestic research.
