Embodiment 1

[0030] (1) Composition

[0031]

[0032]

[0033] All raw materials are local commercial goods.

[0034] (2) Method

[0035] Fully mix the components under stirring to obtain the stock solution of self-permeable anti-resurgence fire extinguishing agent, and set aside;

[0036] (3) Take 3% of the stock solution, add 97% of water, stir and mix to obtain a self-permeable anti-resurgence fire extinguishing diluent with a concentration of 3% for filling the fire extinguisher.

Embodiment 2

[0038] (1) Composition

[0039]

[0040] Take 6% of the stock solution, add 94% of water, stir and mix to obtain a self-permeable anti-resurgence fire extinguishing diluent with a concentration of 6% for filling fire extinguishers.

[0041] The rest are the same as in Example 1.

Abstract

The invention discloses a self-penetrating anti-after combustion fire extinguishing agent. The self-penetrating anti-after combustion fire extinguishing agent comprises the following components in percentage by weight: 1 to 5 percent of sodium dodecyl benzene sulfonate or sodium alkyl naphthalene sulfonate, 0.1 to 1 percent of fluorocarbon surfactant FC4430, 0.5 to 2 percent of carboxymethylcellulose, hydroxyethyl cellulose, cane sugar or oxidized starch, 0.2 to 1 percent of ethylene diamine tetraacetic acid (EDTA) disodium or nitrilotrisodium, 5 to 20 percent of glycol, 1,3-propylene glycol, glycerol, 1,4-butanediol, 2-methyl-2,4-pentanediol or 2,4-hexanediol, 0.1 to 1 percent of sodium stearate, sodium laurate, sodium palmitate or sodium tetradecyl, and the balance of water. The components and the water are stirred to be fully mixed to obtain a primary liquid for later use; and water is added into 1 to 6 percent of primary liquid until the total amount is 100 percent, and then a self-penetrating anti-after combustion fire extinguishing diluent which is 1 to 6 percent in concentration and is used for filling a fire extinguisher is obtained. The diluent is extremely high in penetration and humidification, can quickly penetrate into a combustible object, quickly extinguish fire and quickly reduce temperature, and is after-combustion resistant and environment friendly.

Description

Field of Invention [0001] The invention relates to a high-efficiency self-permeable anti-recombustion fire extinguishing agent with the functions of rapid fire extinguishing, rapid cooling, recombustion resistance, environmental protection and self-permeation and spreading. Background technique [0002] In the fire fighting system, for various fires, whether it is dry powder fire extinguishing agent, gas fire extinguishing agent, or foam fire extinguishing agent, it has its own limitations. Especially for Class B fires, currently more aqueous film-forming foam fire extinguishing agents are used, and there are some deficiencies in high temperature resistance, cooling speed and recombustion resistance. Therefore, there is an urgent need to develop a high-efficiency fire extinguishing agent that combines the characteristics of rapid fire extinguishing, rapid cooling, and anti-resurgence, and has no pollution to the environment to meet the needs of the fire extinguishing market....
