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
Invention field
The present invention relates to a kind of have fire extinguishing rapidly, fast cooling, anti-resume combustion, environmental protection and certainly infiltration spread etc. multi-functional, a kind of from the anti-resume combustion extinguishing chemical of osmosis type efficiently.
Background technology
In the fire-fighting system,, no matter be powder extinguishing agent, gas extinguishing agent for all kinds of fire, or fire foam, limitation is separately all arranged.Particularly, use more aqueous film-forming foam extinguishing agent at present, come with some shortcomings at aspects such as high temperature resistant, cooling rate and anti-resume combustion for the category-B fire.Therefore, the urgent need exploitation is a kind of to integrate characteristics such as fire extinguishing is rapid, fast cooling, anti-resume combustion, and the high-efficiency fire-extinguishant of environmentally safe, to satisfy the needs in fire-fighting fire extinguishing market.
Micro emulsion (Microemulsion, be called for short ME) microemulsion has two types of O/W and W/O, and radius is very little by (10～100nm).Be water, oil, surfactant and cosurfactant etc. mix by proper proportion, and each of spontaneous formation be to the electric charge same sex, appearance transparent or translucent thermodynamically stable dispersion.Generally play stabilization jointly by surfactant and cosurfactant etc.
Microemulsion receives the attention of the world of medicine as pharmaceutical carrier after the eighties in 20th century, but Shang Weiyou is applied to the record of extinguishing chemical.
Particularly dispose the surfactant and the cosurfactant of proper proportion in the water for fire extinguishing agent, make its in fire extinguishing procedure with the report of the spontaneous formation micro emulsion of comburant.
Summary of the invention
The object of the present invention is to provide a kind of from the anti-resume combustion extinguishing chemical of osmosis type.
Its technical scheme is:
Develop a kind ofly, it is characterized in that from the anti-resume combustion extinguishing chemical of osmosis type
(1) preparation of raw material by following mass percent forms:
Neopelex or Negel 1～5%;
Fluorocarbon surfactant FC44300.1～1%;
Carboxymethyl cellulose, hydroxyethylcellulose, sucrose or oxidized starch 0.5～2%;
EDTA disodium or nitrilo trisodium 0.2～1%;
Ethylene glycol, 1, ammediol, glycerine, 1,4 butanediol, 2-methyl-2,4-pentanediol or 2,4-hexylene glycol 5～20%, wherein one or both;
Odium stearate, sodium laurate, palmitic acid sodium or tetradecanoic acid sodium 0.1～1%;
In the percentage composition, surplus is a water;
(2) each component is under agitation fully mixed, obtain from the anti-resume combustion extinguishing chemical of osmosis type stoste, subsequent use;
(3) get stoste 1～6%, add adding water to total amount 100%, stir and make mixing, the acquisition fire extinguisher fills with putting out a fire from the anti-resume combustion of osmosis type of 1～6% concentration and uses dilution.
In this technical scheme; Surfactant and cosurfactant play stabilization jointly; Surfactant is set to anionic surfactant and fluorocarbon surfactant, and cosurfactant is set to odium stearate, sodium laurate, sodium palmitate or tetradecanoic acid sodium.
This extinguishing chemical is through the prescription design; Utilize the efficient infiltration immersional wetting of odium stearate, sodium laurate, palmitic acid sodium or tetradecanoic acid sodium etc.; Rapidly hydrone is mixed with comburant; And can wrap up comburant and burning gases rapidly, and form micro emulsion, thus the effect that reaches fast cooling, completely cuts off rapidly.This extinguishing chemical has not only solved the deficiency of miscellaneous agent at aspects such as the anti-resume combustion property differences of resistance to elevated temperatures, cooling velocity and water-based extinguishing agent, and is a kind of high-efficiency fire-extinguishant of biodegradable environmentally safe.
The application's advantage is:
(1) product of the present invention is a kind of Multifucntional high-efficiency fire-extinguishant, can be used for the fire extinguishing of AB class and part D class fire, is particularly useful for putting out the category-B fire, the fire that particularly causes for petroleum hydrocarbon fuel, and the fire extinguishing effect is very remarkable.
(2) in the product of the present invention; Owing to contain bleeding agent (anionic surfactant, fluorocarbon surfactant) and wetting agent, thereby have extremely strong infiltration and humidification, so that the globule is penetrated into combustible object inside rapidly; Make body surface and inside all be full of the globule; Thereby not only reduce the heat of body surface, also can reduce the heat of interior of articles rapidly, play the effect of efficient resistance heat.
(3) in the product of the present invention,, have extremely strong profit affinity because contained bleeding agent is a surfactant, can be with the emulsification of profit substance dissolves, rapid spread forms barrier layer in oil surface, realizes 100% anti-resume combustion.
(4) in the product of the present invention,, have good cryogenic property, thereby product can be stored under-30 ℃ of low temperature and use owing to contain antifreezing agent.
(5) product of the present invention is based on water and the oxygen enrichment compound is composite forms, and contained material all is a hydrocarbon oxygen compound, and nontoxic, harmless, pollution-free, non-corrosiveness have low BOD/COD, can 100% biodegradation.
Be used as the aqueous film forming foam extinguishing chemical in the fire-fighting industry.
