Abstract
The invention relates to an environment-protecting sound-absorbing fireproof coating for tunnels, belonging to the technical field of fireproof coatings, comprising the raw materials with the following weight proportion: 30 to 50 percent of fire cement, 15 to 30 percent of perlite, 15 to 25 percent of vermiculite, 10 to 30 percent of calcium carbonate or talcum powder and 2 to 5 percent of cellulosic polymeric modifier, wherein, the cellulosic polymeric modifier is preferably hydroxyl ethyl cellulose; the perlite and vermiculite choose two types with the grain diameter being respectively 3mm and 1mm, and the matching proportion of the two types is 7:3; the two types are evenly mixed and then the raw materials are measured and put in a multifunctional mixer for stirring and scattering evenly; the product coating is obtained when qualified. Since cellulosic polymeric modifier is added in the formula and the perlite and vermiculite are carried out rough and fine matching, when the coating is coated on the concrete surface, rough and fine porous surfaces can be formed, endowing the coating with the functions of sound absorbing and vibration resistance based on environment protecting and fire proofing.
Description
Technical field
The invention belongs to the frie retardant coating technical field, refer in particular to the fire-proof coating for tunnels of a kind of environmental protection, sound-absorbing.
Background technology
The passage of communications and transportation is not only in the tunnel, but also is the passage of optical cable, cable even transition pipeline, hydraulic pipe, and therefore, in various car accidents, the rescue of tunnel fire hazard accident is the most difficult, the time that cuts off traffic is the longest, financial loss is also maximum.For improving the fire performance in tunnel, sprayed fire proofing coating is one of the more method of using at present on tunnel lining body.Because tunnel environment humidity, vehicle by the time in the tunnel, can produce high wind and vibrations, therefore, fire-proof coating for tunnels not only will have higher fire performance, very strong cohesiveness and water tolerance, and when burning, do not have the toxic gas generation, also require coating that good sound absorption qualities is arranged.The feature of environmental protection that forms though disclosed tunnel does not have the toxic gas generation with the frie retardant coating water tolerance, when burning is all better, and weak point is that existing frie retardant coating particle diameter is thin, the composition mismatch, and sound-absorbing effect is poor.
Summary of the invention
The object of the present invention is to provide the fire-proof coating for tunnels of a kind of not only environmental protection but also sound-absorbing.
The object of the present invention is achieved like this: frie retardant coating is made up of the raw material of following weight ratio:
Refractory cements 30-50%, perlite 15-30%,
Vermiculite 15-25%, lime carbonate or talcum powder 10-30%,
Cellulose family macromolecule properties-correcting agent 2-5%;
Wherein cellulose family macromolecule properties-correcting agent is preferably Natvosol;
Perlite selection particle diameter wherein is 3mm and 1mm two kinds, and the thickness blend proportion is 7: 3, and thickness mixes; Vermiculite selection particle diameter is 3mm and 1mm two kinds, and the thickness blend proportion is 7: 3; Thickness mixes.
Preparation process is as follows:
It is even to put into multi-functional blender dispersed with stirring after the raw material weighing with above-mentioned weight ratio, detects back up to standard weighing and bagging and becomes coating, notices that atmospheric moisture can not produce when above 85%.
During construction, coating is put into mould wash mixer, add water 40-60% and stir, be sprayed on concrete surface, form the porous surface that thickness differs with the grout shotcrete machine.
Beneficial effect of the present invention is: owing in prescription, added the Mierocrystalline cellulose macromolecule modifier, make coating on the basis of environmental-protection fireproof, can also sound-absorbing, shockproof, and have multiple function.
Embodiment
For further describing the present invention, enumerate following examples:
Embodiment 1
Get refractory cements 500Kg, selecting particle diameter is 3mm and 1mm, the thickness blend proportion is 7: 3 perlite 150Kg, selecting particle diameter is 3mm and 1mm, the thickness blend proportion is 7: 3 vermiculite 200Kg, talcum powder 148Kg, Natvosol 2Kg, be placed in the multifunctional mixer after weighing is good and stir metering packing.
Get 300Kg coating, add 120Kg water and put into grout mixer, open air compressor machine, under 0.3MPa pressure, be sprayed on the concrete tunnel surface, thickness 20mm, fire-resistant more than 2.5 hours, sound-absorbing effect is obvious.
Claims (2)
1. the fire-proof coating for tunnels of an environmental protection, sound-absorbing, it is characterized in that: the raw material by following weight ratio is formed:
