Abstract
The invention relates to a modified expanded and vitrified microbead fire extinguishing agent which comprises the following components in parts by mass: 65-94.5 parts of component A, 0.5-5 parts of component B and 5-30 parts of component C. The component A is expanded and vitrified microbeads; the component B is one or mixture of high-polymer wax, amino resin, organic silicon coupling agent, organosilicon surfactant and fluorine-containing surfactant; and the component C is one or mixture of anionic surfactant, cationic surfactant and nonionic surfactant. The fire extinguishing agent provided by the invention can be quickly spread on an oil surface, suspended stably and covered accumulatively, has the advantage of especially long burn resistance time, and is especially suitable for fire extinguishing rescue of very-large-scale oil tanks.
Description
Technical field
The present invention relates to a kind of extinguishing chemical and preparation method thereof, particularly a kind of modified expanded glass bead extinguishing chemical and preparation method.
Background technology
Fast development along with national energy security implementation and economic society, in order to guarantee the energy security of China, promote the sustainable development of China's economy, the large of oil tank will become the inexorable trend of development, once and Large Scale Oil Storage Tank breaking out of fire, endanger huge, its prevention and rescue situation very severe.
The most frequently used extinguishing chemical of To Extinguish The Fire On Oil is fire foam, mainly contains at present the several types such as albumen, fluorine albumen and MJPZ.Protein foam extinguishing agent fire-fighting efficiency is low, is eliminated gradually; Although fluoroprotein foam extinguishing agent fire-fighting efficiency is higher and cheap, corrosivity is large, the shelf-life is short, and application has been subject to certain limitation; Aqueous film-forming foam extinguishing agent is a kind of foam solution that hc-surfactant and fluorocarbon surfactant be base-material of take, and can on some hydro carbons surface, form water membrane, has the features such as efficient, environmental protection, long shelf-life, but expensive, ability of anti-burning is not high.In GB GB15308-2006 < < fire foam > > regulation low-expansion foam liquid to the anti-burning time of the anti-flat A level (superlative degree) of heating up water of non-water-soluble liquid fuel for being greater than 10min, for some super-huge fire, the duration of fire may reach several hours even several days, and the anti-burning time of aqueous film-forming foam extinguishing agent can not meet the demands.The drainage time of the anti-burning time of aqueous film-forming foam extinguishing agent by foam determines, and improve its drainage time based on prior art, limited to, and therefore need to continually develop fire-extinguishing agent, meets current demand.
Summary of the invention
In order to solve the problem of mentioning in background technology, the invention provides a kind of not only anti-burning but also can swim in the modified expanded glass bead extinguishing chemical that fuel gauge mask has accumulation covering effect.This extinguishing chemical can be sprawled fast on fuel oil surface, form resistant to elevated temperatures solid cover layer, coordinate regular-type foam extinguishing chemical to use, anti-burning time overlength, be applicable to the fire extinguishing of Large Scale Oil Storage Tank, be that Large Scale Oil Storage Tank accident emergency rescue ability key problem in technology urgently to be resolved hurrily improves in fire brigade, there is good application prospect.
A kind of modified expanded glass bead extinguishing chemical of the present invention, by mass parts, comprising: component A, expanded and vitrified small ball, 65～94.5 parts; Component B, chooses a kind of in macromolecule wax, amino resins, organo-silicon coupling agent, organic silicon surfactant, fluorine-containing surfactant or their mixture, 0.5～5 part; Component C, chooses a kind of in anion surfactant, cationic surfactant, non-ionic surface active agent or their mixture, 5～30 parts.
Component A expanded and vitrified small ball is a kind of in expansion vitrification perlite microballon, expansion vitrification pitchstone microballon or their mixture.The described expanded and vitrified small ball microballon that to be perlite, pitchstone particulate obtain through high-temperature expansion and vitreous, the expanded and vitrified small ball that preferred surface vitreous degree is high, specific surface is little.
Component B chooses a kind of in macromolecule wax, amino resins, organo-silicon coupling agent, organic silicon surfactant, fluorine-containing surfactant or their mixture.This component is the capillary surfactant that can change the surface and interface character of component A expanded and vitrified small ball and can reduce water.Above macromolecule wax preferably polyethylene wax; The preferred melmac of amino resins; Organic silicon surfactant comprises amino-modified silicone oil, Carboxyl Modified Polydimethylsiloxane, polyether modified silicon oil, alcohol modified silicon oil, epoxide modified silicone oil, ester modified silicone oil; Fluorine-containing surfactant comprises perfluor stearic acid and salt, perfluoroalkyl benzene sulfonic acid and salt thereof, perfluoroalkyl benzyl quaternary ammonium salt, perfluor AEO, PFPE, perfluor polysiloxanes.Component B preferably has organic silicon surface active agent or fluorine-containing surfactant.
Component C is chosen a kind of in anion surfactant, cationic surfactant, non-ionic surface active agent or their mixture.This component is can be rapidly water-soluble and can produce foam, has closing function.The preferred high surfactant of water solubility rate.
Anion surfactant in component C comprises stearate, alkyl sulfate, alkylsulfonate, alkylbenzenesulfonate; Cationic surfactant comprises fatty amine salt, ethanolamine salt, polyethylene polyamines salt, alkyl benzyl quaternary ammonium salt, heterocyclic ammonium salt or quaternary ammonium salt; Ionic surfactant pack is drawn together ethylene oxide adduct, sorbitan ester, alkylolamides, the APG of AEO, APES, polyoxyethylene carboxylate, polypropylene glycol.
The preparation technology of modified expanded glass bead extinguishing chemical is as follows: component A fully disperses, soaks, mixes through dispersion machine with component B, 60～120 ℃ dry after, then mix with component C.
Utilize the hollow nature of expanded and vitrified small ball to solve its suspension stability on pasta, expanded and vitrified small ball surface modification is improved to its spreading rate on pasta, add surface active composition and obtain sealing effect with the foam producing.First by expanded and vitrified small ball surface modification, then with surface active agent composition, fully disperse, mix, make the modified expanded glass bead extinguishing chemical with good fluidity, extinguishing chemical is brought the scene of a fire with spray gun special into by current and is used for the fire extinguishing of oils fire.
The extinguishing chemical the present invention relates to is sprawled rapid, suspending stabilized on pasta, and accumulation covers, and has advantages of that the anti-burning time is long especially, is especially applicable to the fire fighting and rescue of Large Scale Oil Storage Tank.
