Description

A kind of preparation method of adhesiveness fire-retardant combination
Technical field
The present invention relates to fire-fighting quipment field, the extinguishing chemical field more particularly, to put out a fire, is a kind of viscous specifically The preparation method of attached property fire-retardant combination.
Background technology
Fire extinguisher is a kind of portable Fire extinguisher.Chemical substance is placed in fire extinguisher, to rescue fire extinguishing calamity.Fire extinguisher is One of common fireproofing installation, is stored in public place or the place of fire may occur, filling in different types of fire extinguisher Component it is different, be to aim at different fire alarms and set.It must be noted that during use in order to avoid producing minus effect and causing danger.
Existing extinguishing chemical mainly has two kinds of a foam and dry powder, and two kinds of extinguishing chemicals respectively have a quality, going out in dry powder extinguisher Magnesium sulfate salt is filled in fiery agent to be used to put out a fire dry and be easy to flow attritive powder by tool fire extinguishing effectiveness machine salt a small amount of additive through dry Dry, crushing, the fire-fighting of mixing micro-solid powder group kind extensively using extinguishing chemical and are mainly used for fire extinguisher except metallic fires of putting out a fire to save life and property BC dry powder fire extinguishing agents (sodium acid carbonate) ABC dry powder (magnesium sulfate salt) two class as the outer dry powder fire extinguishing agent of special dry powdered extinguishing chemical is made dry up Powder machine salt volatility solution thing produces free radical with burning journey fuel or property group hairization suppresses negative catalyst and makes combustion chain reaction Disconnected fire extinguishing；Two by dry powder powder fall the reaction of combustion things surface outgoingization and the glassy coating isolating oxygen of high temperature action shape layer is into asphyxia Put out a fire another external dilution oxygen, play certain cooling effect.Fire foam is a kind of small volume, what surface was surrounded by liquid Bubble population, proportion is between 0.001~0.5.Since the proportion of foam is far smaller than the proportion of general flammable liquid, thus can be with The surface of liquid is floated on, forms a foam blanket.Meanwhile foam has certain viscosity again, can be adhered to general The surface of flammable solid.The foam blanket that fire foam is formed on comburant surface, can make comburant surface and air insulated.
The prior art：Chinese invention patent application, application number：201210236483.6 Publication No.：102772877A, A kind of extinguishing chemical is disclosed, the extinguishing chemical is made of the raw material of following each component：0.1-0.2 parts of organic silicone oil, carbamide 2-3 Part, 3.5-4.5 parts of ammonium phosphate, 6.1-6.2 parts of potassium hyperchlorate, 32-35 parts of concentrated latex, 11-12 parts of water.The fire extinguishing of the present invention Agent, can make up the deficiency of general extinguishing chemical, and cost of manufacture is relatively low, and raw material is easy to get, and the making raw material of extinguishing chemical is harmless, Do not pollute, securely and reliably.
Different due to occurring the condition of a disaster of fire in actual life, the fire that different materials occurs not only wants specific aim Selection fire-extinguishing apparatus, more it is noted that selection extinguishing chemical, so could more preferably, faster, safer stamps out a fire.Therefore, carry Prepare that above-mentioned fire-fighting safety is reliable for one kind, the method meaning of efficient extinguishing chemical is extremely important.
