Description
Technical field the present invention relates to a kind of anti-flaming dope, particularly is applicable to the anti-flaming dope that plays anti-fire action that the road surface of mating formation in the vcehicular tunnel applies.
Background technology is accompanied by the fast development of China's motorway, and the quantity of vcehicular tunnel is also in continuous increase.Vcehicular tunnel is as a special road section of highway, length does not wait to several kilometers from hundreds of rice, imagination is at this special road section, in case the automobile circuit fire takes place, automobile goods fire and traffic accident car collision, goods automobile (particularly tank wagon) are overturned the fire that causes, phenomenons such as smog is big, temperature is high, smoke evacuation is difficult, evacuation is difficult, fire attack difficulty can occur, its consequence is hardly imaginable.A lot of these class accidents had taken place in China and foreign countries' highway circle, suffered heavy losses.This shows,, should do one's utmost from all kinds of disaster hidden-troubles of source elimination based on strick precaution for the fire safety problem of vcehicular tunnel.
At present, domestic most of tunnel road surface generally adopts cement concrete or pitch to mat formation, though to a certain extent, the relative bituminous concrete pavement of cement concrete pavement is better than bituminous concrete pavement at aspects such as water tolerance, the feature of environmental protection, and can also avoid obnoxious flavour that pitch comes out to harm that human body caused when mating formation.But, according to domestic and international many studies show that, advantages such as cement concrete has been difficult to satisfy the requirement on road surface in the modern tunnel, and bituminous concrete pavement is comfortable with its driving, noise is little, airborne dust is few, easy to maintenance are widely used, and are the major project materials that is used for the road road construction at present.
The same with most of synthetic polymers, pitch has combustibility in air, along with its as the widespread use of material of construction on engineering, just progressively rise by the danger of the fire that it caused.Especially as long pavement material apart from road surface in the tunnel, in case vehicle fire takes place, bituminous pavement also can be on fire simultaneously or be generated dense smoke, thereby in the difficulty that has increased the weight of fire and personnel escape virtually.For example, the second in the world long tunnel Switzerland St.Gotthard Tunnel fire disaster tragic incident, because the on-the-spot various a large amount of toxic gases that discharge without the material combustion of fire-retardant finish that use, thereby making the very fast at short notice death by suffocation of people, number is 41 people nearly.
In order to solve the fire safety problem on road surface in the tunnel, at present, people reduce the combustibility of bituminous pavement in the tunnel by taking two kinds of different modes.A kind of is to add flame-retardant additive in pitch, by in itself and the pitch during flammable organic compound burning institute decompose and produce material and react, thereby slow down or stop the incendiary chain reaction, reach fire-retardant purpose.Another kind is to adopt to smear the back-fire relief heat-resistant coating on the supercrust of asphalt pavement, makes it to form a kind of densification of good heat-proof quality and spongy or cellular carbonaceous foam layer uniformly, can protect flammable substrates effectively and plays the effect of fire protection flame retarding.Can play flame retardant effect preferably though in pitch, add flame-retardant additive, but only be aimed at mating formation of new road surface, if old road surface is keeped in repair or is improved, then adopt on the supercrust of mating formation and apply anti-flaming dope, like this, both can save cost, cut the waste, can reach fire-retardant purpose again; Can also play certain decoration effectiveness; Shorten the time of interruption of communication simultaneously.
At present, fire prevention mainly is to take to apply anti-flaming dope on the tunnel masonry in the tunnel, and this technology has been tending towards ripe at home.As Ni Jianchun etc. at " brief talking the application of frie retardant coating in underground workss such as tunnel " (" coatings industry ", 2003.5), Mao Chaojun is at " research of environment-friendly type fire-proof coating for tunnels " (" coatings industry ", 2003.5), what old and well-known family is at " Steel Concrete fire-resistance property and tunnel masonry frie retardant coating " (" coatings industry ", 2002.9) in the application of frie retardant coating in the tunnel all proposed, but, described these frie retardant coatings all are used on the tunnel masonry, owing to be not thrust surface, not very strict to the requirement of strength of coating.The report of use anti-flaming dope and argumentation are but seldom on the present road surface of mating formation in the tunnel.
As everyone knows, during presence of fire, cigarette is to produce at first and the most fatal factor, and according to statistics, death toll has 80% to be due to cigarette suffocates in the fire.And in the middle of the existing flame-retarded technology, but seldom have " fire-retardant " and " pressing down cigarette " are mentioned in the same breath, moreover for some superpolymer, it is more even more important than " fire-retardant " " to press down cigarette ", especially the fire retardant of Halogen system is the main source that is fuming of smog, so, can develop a kind of can either be fire-retardant, the efficient flame-retarding agent that can press down cigarette again is the main direction and the trend of anti-flaming dope industry development from now on.
Summary of the invention the objective of the invention is the fire prevention hidden danger that exists at bituminous pavement in the existing tunnel and disclosed a kind of epoxy type asphalt flame-retardant coating, when being coated in tunnel in bituminous pavement on by suitable depth it, not only can play flame retardant effect preferably, and good sticking power arranged also between coating and the bituminous pavement, both increased the shock resistance on road surface, increase the wear resistance of road crust again, met the working conditions and the design specifications on road surface fully.
