AI Technical Summary
Technical Problem
Existing gel materials have poor water retention, are prone to powdering and cracking, and lack sufficient flame retardancy in forest fire prevention and control, making it difficult to effectively construct durable firebreaks.
Method used
Hydroxypropyl methylcellulose (HPMC) and alkaline silica sol are introduced into a water glass matrix to form a stable organic-inorganic hybrid network through physical adsorption and chemical cross-linking, thereby enhancing the gel's water retention, adhesion, and flame retardant durability.
Benefits of technology
It achieves rapid gelation, high foam stability, and good thermal stability, and can maintain the thermal insulation barrier for a long time in high-temperature environments, providing effective fire protection.

Abstract
The invention discloses a forest fire prevention and extinguishment gel material and a preparation method thereof, and the forest fire prevention and extinguishment gel material comprises the following other raw materials in parts by mass: 3 parts of sodium silicate; 0.6 to 0.8 part by mass of hydroxypropyl methyl cellulose; 3-4 parts by mass of sodium bicarbonate and 1 part by mass of lauryl sodium sulfate; and 13-17 parts by volume of alkaline silica sol. The gel material provided by the invention has excellent water-retaining property, high viscosity, strong adhesive power, high foam stability and thermal stability. After combustion, a compact SiO2 carbon layer can be formed, and a lasting physical barrier is formed.
