Abstract
The invention provides a preparation method of a high polymer thickening forest fire extinguishing agent, which comprises 75-100 parts of ammonium sulfate, 200 parts of urea 175-. The preparation method comprises the steps of firstly dissolving ammonium sulfate and urea in water, independently dissolving the macromolecular thickening agent in water, and then mixing and stirring the two aqueous solutions for 0.5-1 h to be viscous. The invention has the advantages that the high molecular agent is used as the thickening agent, so that the fire extinguishing agent has good stability, high effective viscosity and storage resistance, the thickened forest fire extinguishing agent can improve the permeability of combustible substances from tree crowns to the ground surface, keep longer flame spread retarding time, and can be sprayed at higher spraying operation height, thus being safer for fire extinguishers.
Description
Technical field
The invention belongs to fire service inventory fire-fighting quipment field, be specifically related to the preparation method of a kind of macromolecule thickening fire-extinguishing agent for forest.
Background technology
Fire-extinguishing agent for forest can be divided into fugitive extinguishing chemical and long efficient fire-extinguishing chemical two kinds by action time length in the market.Fugitive extinguishing chemical includes pure water, viscous water, fire foam etc., does not the most possess back-fire relief and extinguishing ability after its water evaporates completely；Even and if still there is back-fire relief and extinguishing ability, so this extinguishing chemical is referred to as long efficient fire-extinguishing chemical after being evaporated as aqueous solution moisture such as diammonium hydrogen phosphate, ammonium sulfate, ammonium carbonate, ammonium sulfate.Extinguishing chemical using method generally injection or aerial spraying, but there are one and serious shortcoming, when the most especially carrying out aerial spraying, extinguishing chemical is in descent, flown away the most with the wind in vaporific by after the shearing force of wind, causing the extinguishing chemical that can arrive ground to greatly reduce, even when certain altitude, extinguishing chemical does not arrives ground at all.Therefore extinguishing chemical is carried out thickening is requisite, current extinguishing chemical thickener is broadly divided into two kinds, and one is that clay (such as bentonite) makees thickener, but there is also the shortcoming flown away with the wind；The second is using natural gum as thickener (such as alginic acid glue, pectin, guar gum etc.), but such natural material price comparison is expensive, and existence and stability is bad, easily by problems such as microbial degradations, the most unfavorable to extinguishing agent storage.So the application of macromolecule thickener, it is possible to producing a kind of good stability, the fire-extinguishing agent for forest of the high shelf-stable again of effective viscosity, this extinguishing chemical aloft flies away loss and evaporation loss is few, and covered ground rate is high, and fire-fighting efficiency will be greatly increased.
Summary of the invention
The present invention is directed to fire-extinguishing agent for forest problem of meeting heavy losses when carrying out aerial spraying, it is provided that the fire-extinguishing agent for forest of the high shelf-stable again of the good stability of a kind of macromolecule thickening, effective viscosity.This extinguishing chemical aloft flies away loss and evaporation loss is few, and covered ground rate is high, and extinguishing property is high.
Technical solution of the present invention is, the preparation method of a kind of macromolecule thickening fire-extinguishing agent for forest is formed by following material weight percentage: ammonium sulfate 75-100 part, urea 175-200 part, macromolecule thickener 0.5-1.5 part, water 475-550 part.When preparing thickening fire-extinguishing agent for forest according to inventive formulation, it is necessary to carry out according to following feeding sequence: first by soluble in water to ammonium sulfate and urea, macromolecule thickener is dissolved alone in water, and right latter two aqueous solution mix and blend 0.5h-1h is to thick.
Thickening fire-extinguishing agent for forest prepared by the present invention, fire extinguishing host uses ammonium sulfate and urea, its aqueous solution is neutral, on some on macromolecule thickener sensitive for pH without impact, and the addition of macromolecule thickener can strengthen the toughness of extinguishing chemical, spray use time formed big cloud and mist drip greatly reduce extinguishing chemical skyborne fly away loss and evaporation loss so that ground coverage rate is greatly increased, improve extinguishing property.Thickening fire-extinguishing agent for forest prepared by the present invention has the advantage that the extinguishing chemical of thickening can improve the penetrating power from tree crown to surface fuel, longer retard flame is kept to spread the time, and can spray under higher spraying operation height, safer for fire extinguishing personnel.
Detailed description of the invention
Detailed description of the invention one: a kind of macromolecule thickening fire-extinguishing agent for forest preparation method, is prepared by formula as below, 85 parts of ammonium sulfate, 190 parts of urea, polyacrylamide 1 part, 500 parts of water.Now ammonium sulfate and urea are dissolved in water-soluble, separately polyacrylamide are dissolved in a small amount of water, then by two kinds of aqueous solution mix and blend 0.5h to thick.
Detailed description of the invention two: a kind of macromolecule thickening fire-extinguishing agent for forest preparation method, is prepared by formula as below, 85 parts of ammonium sulfate, 190 parts of urea, polyvinylpyrrolidone 1 part, 500 parts of water.Now ammonium sulfate and urea are dissolved in water-soluble, separately polyvinylpyrrolidone are dissolved in a small amount of water, then by two kinds of aqueous solution mix and blend 0.5h to thick.
Detailed description of the invention three: a kind of macromolecule thickening fire-extinguishing agent for forest preparation method, is prepared by formula as below, 85 parts of ammonium sulfate, 190 parts of urea, polyethylene glycol oxide 1 part, 500 parts of water.Now ammonium sulfate and urea are dissolved in water-soluble, separately polyethylene glycol oxide are dissolved in a small amount of water, then by two kinds of aqueous solution mix and blend 0.5h to thick.
Detailed description of the invention four: a kind of macromolecule thickening fire-extinguishing agent for forest preparation method, is prepared by formula as below, 85 parts of ammonium sulfate, 190 parts of urea, modified paraffin resin 1 part, 500 parts of water.Now ammonium sulfate and urea are dissolved in water-soluble, separately modified paraffin resin are dissolved in a small amount of water, then by two kinds of aqueous solution mix and blend 0.5h to thick.
The present invention is not limited to above-mentioned embodiment, and all employings realize all technical schemes of the present invention with the same or similar method of the present invention and structure, all should be within the scope of the present invention.
