Abstract
The invention discloses a sound-absorbing and moisture-resistant tunnel fireproof coating and a preparation method thereof. The tunnel fireproof coating is prepared from the following raw materials by weight: 50-80 parts of Portland cement, 20-30 parts of polyvinyl acetate emulsion, 20-30 parts of expanded vermiculite, 10-15 parts of rock wool, 15-20 parts of porous starch, 2-4 parts of hydroxyethyl cellulose, 18-20 parts of magnesium hydroxide, 5-8 parts of glass microspheres, 0.5-0.8 part of silyl powder, and 10-15 parts of water. The preparation method includes: mixing the polyvinyl acetate emulsion with water, conducting stirring for 5-10min to mix the materials evenly, then adding Portland cement, porous starch, hydroxyethyl cellulose, magnesium hydroxide and silyl powder, conducting stirring for 10-15min, mixing the mixture evenly, finally adding expanded vermiculite, rock wool and glass microspheres, conducting stirring in a multifunctional mixer to disperse the mixture evenly, and carrying out packaging. The sound-absorbing and moisture-resistant tunnel fireproof coating provided by the invention has the advantages of good fire prevention and heat insulation, good sound-absorbing effect, good weatherability, moisture resistance, stable storage, no toxicity and environmental protection, etc., and has strong adhesion, does not fall off during vehicle vibration and has good crack resistance, and the cracking and powder shedding phenomena are unlikely to appear.
Description
Technical field
The present invention relates to frie retardant coating technical field, particularly relate to moisture resistance fire-proof coating for tunnels of a kind of sound-absorbing and preparation method thereof.
Background technology
In recent years; the market requirement of China's frie retardant coating increases fast; but also have greater room for improvement in product technology and quality, be the structures safety under protection hot environment, the application of frie retardant coating, high-temperature resistant coating and other relevant coating is just more and more extensive.
The passage of communications and transportation is not only in tunnel, but also is optical cable, the cable even passage of transition pipeline, hydraulic pipe, and therefore, tunnel fire residence accident rescue is the most difficult, financial loss is maximum.For improving the fire performance in tunnel, on tunnel lining body, sprayed fire proofing coating is one of method that application is more at present.Because tunnel environment is moist, vehicle by time can produce high wind and vibrations in tunnel, therefore fire-proof coating for tunnels not only has higher fire-resistant heart and brain, very strong cementability, also requires that coating has strong water tolerance and good sound absorption qualities.Current fire-proof coating for tunnels is not moisture resistance, weathering resistance is poor, sound-absorbing effect is poor, and the bad phenomenon such as cracking, shedding easily appear in coating.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, tunnel type frie retardant coating providing a kind of sound-absorbing moisture resistance and preparation method thereof, the frie retardant coating of preparation has that heat insulation fire retardant is good, sound-absorbing effect is good, good weatherability, moisture resistance, shelf-stable, the advantages such as asepsis environment-protecting, there is stronger cementability, firm with base adhesive, can not come off when vehicle vibration, resistance to cleavage is good, not easily occurs cracking, shedding phenomenon.
The present invention adopts following technical scheme to achieve these goals:
The fire-proof coating for tunnels that sound-absorbing is moisture resistance, is made up of the raw material of following weight part: silicate cement 50-80 part, aqueous polyvinyl acetate emulsion 20-30 part, expanded vermiculite 20-30 part, rock wool 10-15 part, porous-starch 15-20 part, Natvosol 2-4 part, magnesium hydroxide 18-20 part, glass microballon 5-8 part, silylation powder 0.5-0.8 part, water 10-15 part.
The particle diameter of described expanded vermiculite is two kinds of 3mm and 1mm, and the ratio of two kinds of particles is 7:3, mixes.
The preparation method of the fire-proof coating for tunnels that described sound-absorbing is moisture resistance, comprise following preparation process: mixed with water by aqueous polyvinyl acetate emulsion by above-mentioned weight ratio, stir 5-10 minute, mix, add silicate cement, porous-starch, Natvosol, magnesium hydroxide, silylation powder again, stir 10-15 minute, mix, finally add expanded vermiculite, rock wool, glass microballon, even by dispersed with stirring in Multifunctional mixer, detect rear packaging up to standard, atmospheric moisture remains on 40-50%.
During construction, frie retardant coating is put into mould wash mixer, the 50-60% that adds water stirs, and is sprayed on concrete surface with shotcrete machine, forms the porous surface that thickness differs.
Compared with the prior art, beneficial effect of the present invention is as follows:
The fire-proof coating for tunnels that sound-absorbing of the present invention is moisture resistance is by adding the raw materials such as aqueous polyvinyl acetate emulsion, Natvosol, porous-starch, glass microballon, silylation powder, improve the sound-absorbing shockproof effect of coating, improve water tolerance and the adhesiveproperties of coating simultaneously; Add aqueous polyvinyl acetate emulsion, improve cementability and the elasticity of coating, water resisting time can reach 30 days, and coating is without aliquation, obscission, has certain elasticity without sex change energy, not easily crack phenomenon occurs; The interpolation of porous-starch, make containing the micropore that interpenetrates in a large number in coating, improve acoustically effective, glass microballon also has high temperature resistant, quality hard and can the effect of noise reduction sound-absorbing; The existing mechanical physics and chemistry function well of frie retardant coating of the present invention, good insulated foam coating can be formed again when being subject to fire, at high temperature also do not come off, sticking power is good, bonding strength, up to 0.4-0.5MPa, can bear the high wind residing for tunnel and vibration environment, and the feature of environmental protection is good, during fire, fire-proof coating for tunnels does not produce toxic gas.
