Embodiment 1

[0029] This embodiment discloses a preparation method of a fire extinguishing agent composition, comprising the following steps:

[0030] In the reaction kettle, add 12.5kg Dupont fluorocarbon surfactant 1115, 6.25kg stearic acid, 3.125kg cocamidopropyl betaine, 3.125kg alkyl glycoside APG 0810 in 460kg water, and stir at 80rpm for 20min to dissolve and form a homogeneous phase Surfactant solution;

[0031] Add 35kg of silicone resin polyether emulsion MPS into 460kg of water, stir at 80rpm for 20min to dissolve to obtain a foam stabilizer solution;

[0032] Add the foam stabilizer solution into the surfactant solution, stir at 80rpm for 20min and dissolve to form a clear and uniform mixed solution;

[0033] Stir 20 kg of sodium lauryl sulfate at 60 rpm for 10 min, add it into the mixed solution, and stir at 80 rpm for 50 min to dissolve to obtain the fire extinguishing agent composition.

Embodiment 2

[0035] This embodiment discloses a preparation method of a fire extinguishing agent composition, comprising the following steps:

[0036] In the reaction kettle, add 20kg of Dupont fluorocarbon surfactant 1115, 6kg of stearic acid, 1kg of cocamidopropyl betaine, 2kg of lecithin, 3kg of alkyl glycoside APG 0810 in 460kg of water, and stir at 100rpm for 30min to dissolve and form a homogeneous phase Surfactant solution;

[0037] Add 30kg of silicone resin polyether emulsion (MPS) into 460kg of water, stir at 100rpm for 30min and dissolve to obtain a foam stabilizer solution;

[0038] Add the foam stabilizer solution into the surfactant solution, stir at 80rpm for 30min and dissolve to form a clear and uniform mixed solution;

[0039] Stir 15kg of fatty alcohol polyoxyethylene ether sodium sulfate at 55rpm for 15min, add it into the mixed solution, stir at 80rpm for 50min and dissolve to obtain the fire extinguishing agent composition.

Embodiment 3

Abstract

The invention relates to the technical field of fire extinguishing agents, and in particular, relates to a fire extinguishing agent composition and preparation and an application thereof. The fire extinguishing agent composition is prepared by compounding a fluorocarbon surfactant, a hydrocarbon nonionic surfactant and a hydrocarbon zwitterionic surfactant; a fluorocarbon chain has excellent hydrophobicity and oleophobicity at the same time, and has high surface activity and good chemical stability and thermal stability; the hydrocarbon nonionic surfactant and the hydrocarbon zwitterionic surfactant are used, so that the use dosage of the fluorocarbon surfactant is reduced, the foam performance and the fire extinguishing performance can be improved, the foam drainage time is prolonged, thestability of a fire extinguishing system is improved, and the foam extinguishing system is not easy to lose; the foam stabilizer and the foaming agent are used, and the fire extinguishing agent composition with rich, fine and stable foam is prepared under the assistance of the surfactant and the foam stabilizer, can rapidly extinguish a fire, and has good fire extinguishing efficiency.

Description

technical field [0001] The invention relates to the technical field of fire extinguishing agents, in particular to a fire extinguishing agent composition and its preparation and application. Background technique [0002] With the rapid growth of my country's economy and society, fires are becoming more and more frequent. How to effectively prevent and control fires has become a very important research content. Carbon dioxide fire extinguishing agent, etc. [0003] Foam fire extinguishing agent is cheap and reliable, but it still relies on physical action to extinguish the fire, and the fire extinguishing efficiency is low; dry powder fire extinguishing agent has high efficiency and fast fire extinguishing speed, but it is easy to cause re-ignition, and has a strong suffocating effect on humans and animals, endangering the safety of humans and animals on the fire site; carbon dioxide The fire extinguishing agent is easy to liquefy, easy to prepare, low cost, less environmenta...
