Abstract
A disclosed tunnel impermeable fireproof paint is prepared mainly by stirring the following raw materials in parts by weight: 20-30 parts of refractory cement, 100-105 parts of sulphoaluminate cement, 30-35 parts of portland cement, bisphenol epoxy resin emulsion, 30-35 parts of polyacrylic acid emulsion, 6-8 parts of magnesium hydroxide, 6-8 parts of starch, 4-8 parts of ammonium bichromate, 5-9 parts of light calcium carbonate, 10-15 parts of hydroxypropyl methyl cellulose, 6-8 parts of glass hollow floating beads, 5-9 parts of diatomite, 10-14 parts of vermiculite, 5-9 parts of aluminium stearate, 10-14 parts of mica and 10-14 parts of potter's clay. 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 bad in waterproof performance; and the fireproof paint is green, environment-friendly, easy to construct and operate and excellent in comprehensive performances, 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 a kind of tunnel antiseepage frie retardant coating, 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 tunnel antiseepage frie retardant coating 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: a kind of tunnel antiseepage frie retardant coating, it is mainly to be stirred and make according to parts by weight proportioning by following raw materials according: 20-30 part refractory cements, 100-105 part aluminosulfate cement, 30-35 part silicate cement, bisphenol epoxies resin emulsion, 30-35 part polyacrylate emulsion, 6-8 part magnesium hydroxide, 6-8 part starch, 4-8 part ammonium dichromate, 5-9 part light calcium carbonate, 10-15 part Vltra tears, 6-8 part glass hollow float bead, 5-9 part diatomite, 10-14 part vermiculite, 5-9 part aluminum stearate, 10-14 part mica, 10-14 part potter's clay.
The particle diameter of described vermiculite is 2-5mm.
Also contain 5-8 part ammonium borate.
Beneficial effect: product of the present invention not only fire resistance is good, but also has water-impervious function, has made up the poor defect of traditional frie retardant coating water-proof function; This frie retardant coating environmental protection, cohesiveness be strong, be easy to constructing operation, high comprehensive performance, is applicable to the fields such as traffic tunnel, people's air defense and hypogee.
