Abstract
A disclosed Tunnel impervious fireproof paint is mainly prepared by stirring the following raw materials in parts by weight: 50-60 parts of sulphoaluminate cement, 30-35 parts of AEC expansive cement, 20-24 parts soybean oil fatty acid alkyd resin, 18-24 parts of acrylate polymer emulsion, 10-12 parts of aluminium hydroxide, 5-8 parts of starch, 10-12 parts of perlite, 5-8 parts of fly ash, 10-12 parts of polypropylene short fiber, 4-8 parts of carboxymethyl cellulose, 10-15 parts of fly-ash glass microsphere, 5-9 parts of diatomite, 5-9 parts of ammonium polyphosphate and 5-8 parts of pentaerythritol. The product provided by the invention not only is good in fireproof performance, but also has water seepage resistant performance, and thus makes up the disadvantage the conventional fireproof paints are easily subjected to water seepage; and the fireproof paint is green, environment-friendly, strong in caking property, easy to construct and operate and excellent in comprehensive performance, and is suitable for the fields such as traffic tunnels, people's air defence buildings, underground buildings and the like.
Description
Technical field
The present invention relates to the impervious frie retardant coating in a kind of tunnel, belong to chemistry painting industry technical field.
Technical background
In architecture, cross-sectional area is surpassed to 30m
2the channel definition of underground artificial construction be tunnel.The task of communications and transportation is not only being born in tunnel, also plays the function of optical cable, cable or even transition pipeline, hydraulic pipe passage.Although the reinforced concrete member as main building in tunnel is non-combustible material, tunnel fire hazard have after burning surrounding temperature raise very fast, the time length is long, ignition range is large, fire suppression and enter the features such as difficult.In the short period of time occurring at fire, the on-the-spot local temperature of catching fire in tunnel can rise to rapidly 1000 ℃, lasting rising along with temperature, in concrete, in conjunction with water, become vapor expansion, produce pressure, cause concrete surface layer to burst, produce large subsiding, tunnel-liner and structure are also damaged, and have aggravated evacuation and rescue personnel's life danger, and its direct losses and indirect loss are huge.Along with being on the increase of China's long tunnel and super long tunnel, the protection of the structure fire in tunnel has been an important research topic.
In the measure of tunnel structure fp, from the accessibility of cost performance and construction, to consider, fire-proof coating for tunnels is the optimal selection of tunnel fire proofing protection.In construction industry and other relevant industries, all kinds of frie retardant coatings have constantly been there are, though can realize fire prevention, but product exists the shortcomings such as the time of complicated, the long-time coating shedding of construction, fire prevention protection is short, concerning people's life security, if must not be a bit careless on fire safety.
Summary of the invention
The impervious frie retardant coating in tunnel that it is good that the object of the invention is to provide a kind of fire resistance.
In order to achieve the above object, the present invention adopts technical scheme to be: the impervious frie retardant coating in a kind of tunnel, it is mainly to be stirred and make according to parts by weight proportioning by following raw materials according: 50-60 part aluminosulfate cement, 30-35 part AEC expansive cement, 20-24 part soy(a)-bean oil fatty acid Synolac, 18-24 part acrylate polymer emulsion, 10-12 part aluminium hydroxide, 5-8 part starch, 10-12 part perlite, 5-8 part flyash, 10-12 part polypropene staple, 4-8 part carboxymethyl cellulose, 10-15 part powder coal ash glass-microballons, 5-9 part diatomite, 5-9 part ammonium polyphosphate, 5-8 part tetramethylolmethane.
Described perlitic particle diameter is 2-5mm.
Also contain 3-5 part ammonium borate.
Beneficial effect: product of the present invention not only fire resistance is good, but also has impervious water function, has made up the easily defect of infiltration of traditional frie retardant coating; The fields such as this frie retardant coating environmental protection, cohesiveness be strong, be easy to constructing operation, be applicable to traffic tunnel, people's air defense and hypogee.
