Abstract
An efficient fire-extinguishing chemical contains F-C-surfactant (25-40 wt.%), C-H-surfactant (10-25), foam stabilizer (10-20), fire-retarding agent (2-8) and solvent (15-25). Its advantages are high effect, high power of preventing recombustion and no environmental pollution.
Description
A kind of new high-efficiency extinguishing chemical belongs to the fire prevention field.
Present domestic extinguishing chemical is mainly chemical foam, dry powder, carbon dioxide, four kinds of extinguishing chemicals of Kazakhstan dragon.Chemical fire foam was eliminated from January 1st, 1998.There are not anti-resume combustion in dry powder and carbon dioxide extinguishing agent, and be harmful, cause deficiencies such as secondary pollution, and halon fire agent also do not found any extinguishing chemical that can substitute so far.
The objective of the invention is to: provide that a kind of anti-resume combustion ability is strong, environmentally safe and the good new high-efficiency extinguishing chemical of extinguishing property.
Extinguishing chemical of the present invention comprises 25～40% (weight) fluorocarbon surfactant, 10～25% (weight) hc-surfactant, 10～20% (weight) foam stabiliser, 2～8% (weight) fire retardants and 15～25% (weight) solvent.Wherein, fluorocarbon surfactant can be anion, cation, both sexes or non-ionic surface active agent, generally is mixed type; Hc-surfactant can be anion, cation, both sexes or non-ionic surface active agent; Foam stabiliser is butyl glycol ether or diethylene glycol butyl ether; Fire retardant is a phosphate; Solvent is cellosolve, carbitol or Dow alcohol.
Fluorocarbon surfactant is the key component of this extinguishing chemical, its effect is the surface tension that reduces water mixed liquid, improve foam oleophobic ability, and combine with hc-surfactant, make the mixed liquor of extinguishing chemical can on the HC fuel surface, promptly expand the formation moisture film that comes, thereby the quickening coverage speed reaches the purpose of quick extinguishing.
The effect of hc-surfactant, the one, reduce interfacial tension, make fluorocarbon surfactant be easy to work to help film at the hydro carbons surface filming; The 2nd, the stability of raising foam plays the foaming agent effect; The 3rd, the uniformity of mediation system plays the cosolvent effect.
The main effect of foam stabiliser is the stability that strengthens moisture film and foam, and they are some natural or synthetic water soluble compounds.
In water, add fire retardant to improve the anti-resume combustion ability after putting out a fire.
Evidence: this extinguishing chemical has reached effect of the present invention.
Embodiment: 1,25% fluorine carboanion surfactant, 25% hydrocarbon cationic surfactant, 20% butyl glycol ether, 5% sodium phosphate, 25% cellosolve are mixed in reactor, after reacting 2 hours under normal temperature, the normal pressure, sedimentation.2,40% fluorine carbocation surfactant, 20% hydrocarbon anion surfactant, 15% diethylene glycol butyl ether, 8% potassium phosphate, 17% carbitol are mixed in reactor, after reacting 2 hours under normal temperature, the normal pressure, sedimentation.
