Abstract

The invention discloses a dilute thickening type aqueous film-forming foam fire extinguishing agent and a preparation method thereof. The fire extinguishing agent includes the following components by mass fraction: 4-8% fluorocarbon surfactant, 2-10% foaming agent, 2-7% anti-burning agent, 5-15% antifreeze agent, foam mixture Thickening agent 6~15%, foam concentrate viscosity reducing agent 5~10%, preservative 0.5~1.5%, pH regulator 0.1~0.3%, and industrial soft water as the balance. Add industrial soft water into the reaction kettle, add foam concentrate viscosity reducer, fluorocarbon surfactant, foaming agent, anti-burning agent, antifreeze agent, preservative in turn under stirring, and stir for 20 minutes; then add foam mixture to increase Viscous, continue to stir; adjust the pH to control the pH value of the product to be less than 9; fill after standing still for defoaming. The foam fire extinguishing agent of the invention has good foam stability, good adhesion, high fire extinguishing and cooling effects, and a simple preparation method, which is suitable for industrialization.

Description

technical field [0001] The invention relates to the technical field of foam fire extinguishing agents, in particular to a dilute thickening type aqueous film-forming foam fire extinguishing agent and a preparation method thereof. Background technique [0002] For the three-dimensional three-dimensional fire of Class B oil fire, the foam requires a certain degree of adhesion. On the one hand, it can enhance the foam stability of the product and achieve better fire extinguishing and anti-burning performance; on the other hand, the foam adhered to the solid surface , can prevent the further occurrence of fire, and at the same time achieve a better cooling effect. [0003] Existing aqueous film-forming foam fire extinguishing agents have relatively low viscosity. After dilution by 1% to 6%, the viscosity of the foam mixture is basically not much different from that of water, and the formed foam is difficult to exist on the solid wall for a long time. The foam mixture of the sol...
