Abstract
The invention discloses a kind of Seepage-resistant tunnel fireproof paint, it is mainly made up according to the stirring of parts by weight proportioning of following raw materials according: 100-105 part refractory cements, 20-30 part Portland blast furnace slag cement, 30-35 part acrylate polymer emulsion, 10-15 part allyl acetate resin emulsion, 5-7 part sodium hydroxide, 10-15 part perlite, 4-8 part flyash, 3-4 part ammonium dichromate, 2-6 part light calcium carbonate, 10-16 part polypropene staple, 2-6 part carboxymethyl cellulose, 7-9 part diatomite, 4-9 part vermiculite, 3-8 part ammonium polyphosphate, 5-8 part potter's clay, 3-5 part tetramethylolmethane.The not only fire resistance of product of the present invention is good, but also has water-impervious function, compensate for the defect of traditional frie retardant coating water-proof function difference; This frie retardant coating environmental protection, cohesiveness is strong, be easy to constructing operation, high comprehensive performance, is applicable to the fields such as traffic tunnel, people's air defense and hypogee.
Description
Technical field
The present invention relates to a kind of Seepage-resistant tunnel fireproof paint, 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 on coagulation, Bound moisture becomes vapor expansion, produces pressure, causes coagulation upper epidermis 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 good Seepage-resistant tunnel fireproof paint of a kind of fire resistance.
In order to achieve the above object, the present invention adopts technical scheme to be: a kind of Seepage-resistant tunnel fireproof paint, it is mainly made up according to the stirring of parts by weight proportioning of following raw materials according: 100-105 part refractory cements, 20-30 part Portland blast furnace slag cement, 30-35 part acrylate polymer emulsion, 10-15 part allyl acetate resin emulsion, 5-7 part sodium hydroxide, 10-15 part perlite, 4-8 hinders flyash, 3-4 part ammonium dichromate, 2-6 part light calcium carbonate, 10-16 part polypropene staple, 2-6 part carboxymethyl cellulose, 7-9 part diatomite, 4-9 part vermiculite, 3-8 part ammonium polyphosphate, 5-8 part potter's clay, 3-5 part tetramethylolmethane.
Described perlitic particle diameter is 2-5mm.
Also containing 4-8 part ammonium borate.
Beneficial effect: product of the present invention not only fire resistance is good, but also has water-impervious function, compensate for the defect of traditional frie retardant coating water-proof function difference; This frie retardant coating environmental protection, cohesiveness is strong, be easy to constructing operation, high comprehensive performance, is applicable to the fields such as traffic tunnel, people's air defense and hypogee.
