Preparation method for compound coordination type type-A, B and E water system fire extinguishing agents

Abstract

The invention belongs to the technical field of fire extinguishing agents and particularly relates to a preparation method for compound coordination type type-A, B and E water system fire extinguishing agents. According to the water system fire extinguishing agent prepared by the preparation method, the defects that a traditional water system fire extinguishing agent cannot extinguish a type-E fire disaster, a secondary fire disaster or other accidental casualties are caused by electric short circuit and electricity leakage at the time of fire extinguishing, and the potential safety hazard is brought for personnel rescue and evacuation are overcome, and the electrification type-E fire disaster below 36 KV can be extinguished while type-A and B fire disasters can be extinguished.

Description

technical field

[0001] The invention belongs to the technical field of fire extinguishing agents, and in particular relates to a preparation method of compound synergistic type A, B, and E water-based fire extinguishing agents. Background technique

[0002] The traditional compound synergistic type A and B water-based fire extinguishing agents quickly extinguish solid substances such as wood, cotton, Class A fires of wool, hemp, paper and their products, and Class B fires of liquid or meltable solids, such as gasoline, kerosene, diesel oil, crude oil, methanol, ethanol, asphalt, paraffin, etc. The functional components form a high-temperature-resistant, heat-insulating, and flame-retardant covering layer on the surface of combustibles to play an anti-reburning effect. Because Class A and B fires involve many occasions in daily life and production activities, the fire extinguishing agent can be used for fire prevention in households, urban buildings, oil depots and gas stati...

Examples

Embodiment 1

[0019] The components and weight ratios of the composite synergistic A, B, and E water-based fire extinguishing agents provided in this example are: 54% deionized water; 4.0% ammonium polyphosphate; 1.6% ionic hydroxyethyl cellulose polymer; Dialkyl imidazoline 10.3%; Hydrocarbon surfactant 17.5%; Coco alkyl betaine 12%; Fluorosurfactant 0.6%.

[0020] Its preparation method comprises the following steps:

[0021] (1) Prepare deionized pure water quality, its conductivity ≤ 5us / cm;

[0022] (2) adding ammonium polyphosphate to the deionized water, stirring for 2.5 hours and then standing for 2 hours;

[0023] (3) Add ionic hydroxyethyl cellulose polymer, dodecyl imidazoline, hydrocarbon surfactant, coconut oil alkyl betaine in turn; then stir for 4 hours;

[0024] (4) Add fluorosurfactant to the solution described in (3), and then stir for 1.5 hours to check that the conductivity of the solution is less than or equal to 50 us / cm;

[0025] (5) Packaging and storage.
