Problems solved by technology

[0003] But at present, the fluidity of the synthetic foam fire extinguishing agent is poor, so that the thickness of the film produced by the fire extinguishing agent during use is uneven, and the covering ability is poor. Due to the uneven thickness of the film, the fire reduction speed in some areas is slow , the fire extinguishing effect is poor, and it is easy to reignite

Abstract

The invention discloses an environment-friendly foam extinguishing agent. The extinguishing agent is prepared from raw materials in percentage by mass as follows: 15%-19% of a foaming agent, 0.2%-0.5%of xanthan gum, 2%-5% of an anti-freezing agent, 0.2%-0.6% of a fluorocarbon surfactant and 75%-82% of water. The invention also discloses a preparation method of the environment-friendly foam extinguishing agent. The method comprises the steps as follows: (1) adding water to a reactor, and adding xanthan gum and diethylene glycol to be dissolved; (2) adding urea and keeping stirring for dissolution; (3) adding the fluorocarbon surfactant and keeping stirring; (4) adding cellulose acetate butyrate and azodicarbonamide potassium formate, and performing stirring for 1 h to finish preparation. The environment-friendly foam extinguishing agent can form films with uniform thickness during usage and has high covering capacity.

Description

technical field [0001] The invention specifically relates to an environment-friendly foam fire extinguishing agent and a preparation method thereof. Background technique [0002] Synthetic foam fire extinguishing agent is an environmentally friendly foam fire extinguishing agent with a wide range of uses. Compared with fluoroprotein fire extinguishing foam, it has a higher fire extinguishing rate and higher fluidity. As a substitute for fluoroprotein foam fire extinguishing agent, it is suitable for Among various low-multiplier fire extinguishing systems, it is widely used in oil depots, petrochemical enterprises, ships and other units with a large amount of oil products to extinguish large-scale oil fires. Synthetic foam fire extinguishing agent will produce a large amount of foam when it is used. These foams can dilute the oxygen content in the fire area after being sprayed into the fire area, and cover the surface of the burning object, so that the burning object loses th...
