Abstract
The invention discloses the impervious frie retardant coating in a kind of tunnel, it is mainly made up according to the stirring of parts by weight proportioning of 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.Product of the present invention not only fire resistance is good, but also has impervious water function, compensate for the defect that traditional frie retardant coating easily seeps water; The fields such as this frie retardant coating environmental protection, cohesiveness is strong, be easy to constructing operation, be applicable to traffic tunnel, people's air defense and hypogee.
Description
Technical field
The present invention relates to the impervious frie retardant coating in a kind of tunnel, belong to technical field of chemical paint.
Technical background
In architecture cross-sectional area more than 30m
2the underground channel definition of manually building be tunnel.Tunnel not only carries the task of communications and transportation, also plays the function of optical cable, cable or even transition pipeline, hydraulic pipe passage.Although be non-combustible material as the reinforced concrete member of main building in tunnel, after tunnel fire hazard has burning surrounding temperature raise very fast, the time length is long, ignition range is comparatively large, fire suppression and enter the features such as difficult.Within the short period of time that fire occurs, on-the-spot local temperature of catching fire in tunnel can rise to rapidly 1000 DEG C, along with the lasting rising of temperature, in concrete, Bound moisture becomes vapor expansion, produces pressure, causes concrete surface layer to burst, produce large subsiding, tunnel-liner and structure are also damaged, and exacerbate evacuation and the life danger of rescue personnel, its direct losses and indirect loss huge.Along with being on the increase of China's long tunnel and super long tunnel, the structure fire protection in tunnel has been an important research topic.
In the measure of tunnel structure fp, consider from the accessibility of cost performance and construction, fire-proof coating for tunnels is the optimal selection of tunnel fire proofing protection.All kinds of frie retardant coating has constantly been there is in construction industry and other relevant industries, though fire prevention can be realized, but the shortcomings such as the time that product also exists complicated, the long-time coating shedding of construction, fire prevention is protected is short, concerning the life security of people, if must not be a bit careless on fire safety.
Summary of the invention
The object of the invention is to provide the impervious frie retardant coating in the good tunnel of 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 made up according to the stirring of parts by weight proportioning of 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 containing 3-5 part ammonium borate.
Beneficial effect: product of the present invention not only fire resistance is good, but also has impervious water function, compensate for the defect that traditional frie retardant coating easily seeps water; The fields such as this frie retardant coating environmental protection, cohesiveness is strong, be easy to constructing operation, be applicable to traffic tunnel, people's air defense and hypogee.
