Abstract
The invention relates to a fire resistant paint. The comprised components their weight are as follows: bulking vermiculite 15- 25 kg, bulking pearlite 10- 20 kg, Portland-slag cement 30- 65kg, carboxymethyl cellulose 1- 5kg, glycol cellulose 0.5- 1kg, glass fiber 1- 5kg; the liquid material and weight are as follows: propyl benzene emulsion 50 -70kg, water 20- 40kg. The operational steps for utilization are: mixing bulking vermiculite, bulking pearlite, Portland-slag cement, carboxymethyl cellulose, glycol cellulose, glass fiber according to said weight, mixing propyl benzene emulsion with water, stirring, mixing powder material, liquid material and water according to proportion of 20: 2: 18, stirring into slurry; coating it on the surface of base material, keeping coating wet and maintaining for more than 20 days.
Description
Technical field
The present invention relates to a kind of frie retardant coating, especially relate to a kind of fire-proof coating for tunnels and constructional method thereof.
Background technology
Along with developing rapidly of China's road traffic construction, highway, railway, subway and city are crossed the tunnel, street and have been obtained fast development, in addition, the tunnel still is the important channel that optical cable, oil transportation supply water, in case so presence of fire in the tunnel, tend to cause great loss of life and personal injury, bring serious financial loss, so, strengthen tunnel fire proofing work, have tangible social effect and economic implications for environmental protection, traffic safety.In tunnel fire proofing work, comparatively effective measures are to smear frie retardant coating at concrete surface, to improve the fire endurance of tunnel construction body of material and accessory structure.
Summary of the invention
It is good that the present invention mainly provides a kind of fire resistance, and cohesive force is strong, freeze proof, moisture resistance, water-fast, the fire-proof coating for tunnels that weather resisteant is good.
Above-mentioned purpose of the present invention mainly is achieved by following technical proposals: the raw material of fire-proof coating for tunnels comprises powder and liquid material, its powder is formed: expanded vermiculite 15Kg～25Kg, pearlstone 10Kg～20Kg, Portland blast 30Kg～65Kg, carboxymethyl cellulose 1Kg～5Kg, Natvosol 0.5Kg～1Kg, glass fibre 1Kg～5Kg; Its liquid material is formed: benzene emulsion 50Kg～70Kg, water 20Kg～40Kg.
The operation steps that obtains effective finished product is:
A: expanded vermiculite, pearlstone, Portland blast, carboxymethyl cellulose, Natvosol, glass fibre pulverized by weight mix;
B: benzene emulsion and water are mixed;
C: in powder: liquid material: the ratio of water=20: 2: 18 stirs into mud oar shape and gets final product;
D: remove the greasy dirt on construction substrate surface, floating ash, foreign material;
E: at substrate surface spraying said mixture, coating thickness needs spraying 3～5 times between 3～8mm, each spray time 8～20 hours at interval;
F: keep coating moistening, maintenance is more than 20 days.
Wherein, expanded vermiculite is a laminate structure, and interlayer contains crystal water, and rate of expansion is between 5～25 times, and thermal conductivity is little, and unit weight gently the highest adaptive temperature can reach 1100 ℃, has excellent electric insulating, is good lagging material; Pearlstone is a vesicular structure, and it is light to have unit weight, and chemical stability is good, and high-temperature melting moment is expanded by heating sharply, thereby forms the porous heat-insulating layer, stops heat to transmit to the tunnel masonry; It is more that terra alba contains crystal water, heat absorption dehydration when being heated, for heat insulation the synergism that expand, carboxymethyl cellulose itself is a kind of anionic macromolecular compound, odorless, nontoxic, tasteless, and it is soluble in water, it is neutral that the transparence liquid that forms is, and to light and thermally-stabilised, has good water absorbability, be insoluble to acid, cresols, ethanol, acetone, chloroform, benzene etc., with good water-soluble and film-forming properties; Natvosol is the non-ionic type water-soluble polymers, and it can play thickening, bonding, emulsification, dispersion, stabilization in solution, and can keep moisture content, forms film and the colloid that protection is provided; In addition, the effect of glass fibre also is based on heat insulation, benzene emulsion is because of having good chemical stability, machinery, freeze-thaw stability, sticking power, water tolerance, particularly has levelling property preferably, affinity, the transparency of filming can form evenly good overlay film at building material surfaces such as concrete.
Therefore, it is reasonable that the present invention has component, and finished product cohesiveness height, nontoxic no flue gas etc. pollute the characteristics that composite environmental-friendly requires, and water-tolerant, cost is low, be about normal thick formed steel construction coating 2/3 and can substitute frie retardant coating on the prestressed concrete, this coating is the furnishing shades of colour on request, has certain decorative effect, its weather resisteant is good, has overcome the shortcoming of slim and ultrathin organic fire prevention coating weather resisteant difference, easy construction, but mechanically spraying also can manually be smeared.
Embodiment
Below by embodiment, technical scheme of the present invention is described in further detail.
Embodiment: the raw material of fire-proof coating for tunnels comprises powder and liquid material, and its powder composition is by ratio of weight and the number of copies: expanded vermiculite 25Kg, pearlstone 20Kg, Portland blast 45Kg, carboxymethyl cellulose 4Kg, Natvosol 1Kg, glass fibre 5Kg; Its liquid material is formed: benzene emulsion 60Kg, water 40Kg.
The operation steps that obtains effective finished product is:
A: expanded vermiculite, pearlstone, Portland blast, carboxymethyl cellulose, Natvosol, glass fibre pulverized by weight mix;
B: benzene emulsion and water are mixed;
C: in powder: liquid material: the ratio of water=20: 2: 18 stirs into mud oar shape and gets final product;
D: remove the greasy dirt on construction substrate surface, floating ash, foreign material;
E: at substrate surface spraying said mixture, coating thickness is 5mm, needs spraying 3 times, each spray time 12 hours at interval;
F: keep coating moistening, maintenance is more than 20 days.
At last, should be pointed out that above embodiment only is the more representational example of the present invention.Obviously, technical scheme of the present invention is not limited to the foregoing description, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from content disclosed by the invention all should be thought protection scope of the present invention.
