Description
Technical field
The present invention relates to fire prevention and sound-absorbing application composition, be particularly related to the fire prevention and the sound-absorbing application composition that contain gypsum, cement and porous light aggregate, its strength reduction is avoided on its steel construction surface that is coated on buildings, and the heat of avoiding fire makes its strength reduction, perhaps is coated on the body of wall of buildings or top ceiling with sound insulation.
Background technology
Along with the development of Building technology, the more and more Gao Yueda that buildings becomes, and with the alternative concrete structure of steel construction.The advantage of steel construction is easily to build with laborsaving.Yet, when steel construction is used for large-scale tall buildings, when fire takes place, because flame and toxic gas that the interior of building material causes will cause injures and deaths danger.And when building fire, because its steel structure intensity of heat will lower, buildings will collapse owing to deadweight.Thus, must apply fire-retardant material on the steel construction surface.
The fire prevention coating material can be divided into based on the inorganic coating material of perlite, vermiculite or asbestos with based on the organic coat material of expanded polystyrene according to its main component.The coating method of these fire-retardant materials can be divided into models treated method and pasty state spraying method.These frie retardant coatings have had significant improvement on performance.
Especially, fire-retardant material has had very big technical progress in solar heat protection.Having the heat absorption materials with function during in other words, by use high temperature makes the fire resistance of material that very much progress be arranged.When high temperature, have the heat absorption materials with function and when fire, absorb heat on every side, decompose the key (dehydration or generation carbon dioxide) of self simultaneously and be transferred to the fire resistance that increases fire-retardant material on the steel construction by stoping to damage.Yet, have the heat of heat absorption materials with function around absorbing, take off the water that key connects or be converted into carbonic acid gas its volume-diminished simultaneously.This causes the coating material volume-diminished, form big crackle, and coating material is in the steel construction surface porosity.When serious, coating material comes off in fire, and like this, steel construction is exposed to fire, and its intensity will weaken.
In the prior art, use the inorganic fibre head it off, but organic fibre, asbestos and glass fibre ban use of, because their Diazolidinyl Ureas, even cause eruption.In addition, in coating material, use fine perlite to have good thermal protective performance, because fine perlite has low heat conductivity and the volume thermal distortion is minimum as the insulation aggregate.Yet fine perlite uses very difficult in fire prevention and sound absorbent material, because its function when absorbing water in a large number reduces, and can break during dry shrinkage.
In relevant prior art, publication number is the Korean Patent of No.92-3227, Japanese patent application publication No. 6-32666, disclosed coating material is extremely harmful among the 6-32667, because they contain a large amount of reemulsification powdexes, therefore, in fire, will produce a large amount of obnoxious flavoures.In addition, as when using a small amount of reemulsification powdex, small gap will occur, medium-sized and large-scale breach also can occur.
Korean patent application No.10-1999-0057383 (name be called: fire prevention application composition) discloses and has a kind ofly contained inorganic fibre () coating material for example: asbestos and glass fibre, its skin irritation is harmful to human body.
The korean patent application No.10-1999-0020242 that the applicant applied on June 2nd, 1999 (name is called: the application composition of fire prevention and sound-absorbing), and its its Tai-Ace S 150 of disclosed coating material (Al

3) and unslaked lime between hydration reaction increase crystal water, therefore increased thermal protective performance.Yet, because Tai-Ace S 150 (Al
2(SO
4)
3) and unslaked lime between hydration reaction, need a large amount of water at the building operation mixing step.Therefore, for guaranteeing the flowability of mixture, need the excessive water that adds.Excessive water becomes free water after hydration reaction, therefore, can cause behind the drying shrinkage and break.
Meanwhile, the sound-absorbing coating material can be divided into wrong junction type coating material and the outer spary coating type coating material that sprays that is used for buildings top ceiling, wall and bottom according to building type.In addition, also can be divided at high-frequency region panel vibration type and the resonance type sound absorbent material that has the porous sound absorbing material of good acoustic absorptivity, has good acoustic absorptivity at low frequency range according to material component.
The spary coating type sound absorbent material is by mixing inorganic fibre, belt, tackiness agent, mineral oil and other organic additives are made or be that main raw is made with vermiculite and vegetable fibre.Though they can provide certain sound-absorbing and insulation effect, with experience in the past, inorganic fibre has the danger that produces dust, therefore needs careful operation.And sound absorbent material in the past needs the schedule of operation of trouble after spraying, as hardening treatment to obtain ideal intensity.

Shown in reaction formula 2, work as CaSO
4When not enough, the product that obtains is a monosulfate.Yet, because this monosulfate has hexagonal plate-like microstructure, make hydrated product loose, do not have swelling property, and contain small amount of crystalline water, therefore, it does not have the resist drying shrinkability of fire prevention coating material requirement and improved anti-hot.Therefore, in order when using the CSA compound, to prevent dry shrinkage and to promote anti-hotly, must allow the CaO and the CaSO of sufficient quantity
4Reaction is to generate ettringite.Here, the CaO and the CaSO that are used for CSA compound hydration reaction
4Both can obtain, also can obtain from cement or gypsum as tackiness agent from unslaked lime.
When cement was used as tackiness agent, the CaO that is used for CSA compound hydration reaction was a 0-75% weight based on CSA compound 100% weight, and cement is general portland cement, when use contains the cement of flying dust and slag, is 55-125% weight.
When based on present composition total amount less than the CSA compound of 2% weight and unslaked lime as heat absorption with when reducing shrink-down material, be difficult to expectation snap cure and desirable expanded feature, this will lower main binding agent dry shrinkage.In addition, when usage quantity surpasses 30% weight, the anti-hot of composition will increase, but cost will rise, the economic benefit reduction, and the curing risk of crack that occurs now and then in early days, and occur improper expanded.Owing to these reasons, the consumption of heat absorption and attenuating shrink-down material is a 2-30% weight.
Fire prevention of the present invention and sound-absorbing application composition contain, and except heat absorption with lower shrink-down material, also comprise lightweight aggregate, tackiness agent, common or contain the carbonization sound absorbent material and the additive of flame delayed-action activator.Hereinafter, the preparation details of these components will be described in detail.
The order number of lightweight aggregate is the 4-200 order, comprise the natural inorganic material, as expanded and unpuffed perlite, float stone, vermiculite or volcanic ash, organic aggregate, as precipitate expanded polystyrene or pulverize expanded polystyrene, and hollow ball, it is by artificially making at one-tenth pore on glass, its two or more mixture.
The lightweight aggregate has lower proportion, is 0.01-0.1g/cc, and is therefore very low to the load of buildings.In addition, these lightweight aggregates wherein form a large amount of trickle pores, so it has low-thermal conductivity, are 0.03-0.04kcal/mh ℃, have good sound absorption, insulativity and intensity.Therefore, the lightweight aggregate has increased coating material fire line, insulativity and sound absorbing.Fine perlite has good anti-hot, insulativity and the long-pending stability of hot body, therefore, compares with the organic or inorganic aggregate, has more advantage as heat insulation material.In addition, foodstuff additive are harmless and can not produce objectionable impurities in fire.
In the gross weight of composition, the usage quantity of aggregate is no more than 50 weight %, and its advantage is that density, the heat conductance of spray coating material is lowered, but the tack of coating material and intensity are with step-down.On the other hand, when the usage quantity of lightweight aggregate less than 3% the time, the tack and the intensity of spray coating material improve, and the unfavorable factor of density and thermal conductivity will increase.Therefore, in the gross weight of composition, the preferred 3-50 weight of the usage quantity of lightweight aggregate %.

If the usage quantity of tackiness agent surpasses 80 weight % in the gross weight of composition, it is fine that the tack of coating material and intensity will become, but density and thermal conductivity will increase, and this will worsen the fire line of coating material.Compressing power in the application composition causes big crackle thus with very big and local increasing the weight of.In addition, less than 30 weight %, the density of coating material and thermal conductivity are with step-down as its usage quantity, and tack and intensity are with variation.Owing to these reasons, in the gross weight of composition, the usage quantity of tackiness agent is preferably 30-80 weight %.
Carbonization acoutic fibre board common or that contain the flame delayed-action activator both can be selected from paper pulp, carbon fiber, cotton yarn, polyethylene fibre, styroflex and dissolving pulp, also can be that one of them plants the mixture with the flame delayed-action activator.
Common or the carbonization acoutic fibre board that contains the flame delayed-action activator can limit big crackle that the contraction owing to fire prevention and sound-absorbing composition causes and the generation that comes off when fire takes place.Along carbonization is the slit that carbonizedfibres forms, and forms arachnoid crackle on coating material, so compressing appearred disperseing in coating material, and coating material forms on the steel construction surface and adheres to.Thus, carbonizedfibres stops the temperature on steel construction surface to raise, and at the big crackle and the place that comes off, raises owing to thermoosmosis causes temperature.The decomposition temperature of carbonizedfibres is 350-450 ℃, can improve by adding the flame delayed-action activator.
In application composition total amount of the present invention, if the common or carbonization acoutic fibre board moral consumption that contains the flame delayed-action activator less than 2 weight %, will be difficult to produce enough fine crack and ideal sound-absorbing effect.If its usage quantity is higher than 20 weight %, the intensity of coating material will obviously reduce.Therefore, the preferred 2-20 weight of the usage quantity of carbonizedfibres %.
The length of acoutic fibre board is preferably less than 30mm because, when its length greater than 30mm, in building operation, be difficult for forming coating material.
