Abstract
A sound-absorbing type tunnel fireproof paint is mainly prepared by stirring the following raw materials in parts by weight: 70-78 parts of sulphoaluminate cement, 30-38 parts of AEC expansive cement, 20-30 parts of portland cement, 30-35 parts of methyl methacrylate, 10-18 parts of vinyl acetate resin emulsion, 12-14 parts of aluminium hydroxide, 4-8 parts of starch, 3-6 parts of ammonium bichromate, 10-18 parts of light calcium carbonate, 10-15 parts of polypropylene short fiber, 8-10 parts of carboxymethyl cellulose, 10-16 parts of fly ash glass microsphere, 5-9 parts of kaoline, 5-9 parts of vermiculite and 5-7 parts of ammonium polyphosphate. The product provided by the invention is long in fireproof time, good in adhesive property and convenient to construct, is applicable to various tunnel walls, and has the sound absorbing function based on the fireproof function.
Description
Technical field
The present invention relates to a kind of sound absorption-type fire-proof coating for tunnels, 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 object of the invention is to provide the sound absorption-type fire-proof coating for tunnels that a kind of fire resistance is good.
In order to achieve the above object, the present invention adopts technical scheme to be: a kind of sound absorption-type fire-proof coating for tunnels, it is mainly to be stirred and make according to parts by weight proportioning by following raw materials according: 70-78 part aluminosulfate cement, 30-38 part AEC expansive cement, the white special blue cement of 20-30 part, 30-35 part methyl methacrylate, 10-18 part vinyl acetate resin emulsion, 12-14 part aluminium hydroxide, 4-8 part starch, 3-6 part ammonium dichromate, 10-18 part light calcium carbonate, 10-15 part polypropene staple, 8-10 part carboxymethyl cellulose, 10-16 part powder coal ash glass-microballons, 5-9 part kaolin, 5-9 part vermiculite, 5-7 part ammonium polyphosphate.
The particle diameter of described vermiculite is 2-5mm.
Also contain 5-7 part ammonium borate.
Beneficial effect: product the present invention of the present invention has that when fire prevention limit for length, adhesion property are good, easy construction, is applicable to various tunnels wall, function that simultaneously can also sound-absorbing on fp basis.
