Description
Technical field
The present invention relates to a kind of dipping glue, especially a kind of compound dipping glue and using method thereof for preparing fireproof heated board.
Background technology
The A level was not fired the problem that lagging material exists in the past:
(1) polyurethane foam material
The oxygen index of urethane only has 26, connects B2 level fire prevention (O
2Index 〉=27) all do not reach, even easily produce disaster hidden-trouble in construction at the scene; In addition, it belongs to expansion type closed pore system, adopts on-the-spot integral spray construction in addition, bring obstacle must for the evaporation of steam in newly-built body of wall from now on, thereby produce the series of problems such as bulge, cracking, seepage; Moreover, for buildings, need to reserve wall pipe hole, air-conditioning hole etc. or later stage to punch, and the on-the-spot integral construction of urethane is exactly repaired to the later stage and is brought obstruction; And, polyurethane system need to rely on interfacial agents that sticking power is provided, that smearing all of bonding or anti-crack mastic with basic unit will rely on interfacial agents, globality, the cohesive strength of polyurethane system have been affected greatly, adding it, affected by ultraviolet ray and temperature easily aging, due to the bonding reason such as not tight cause exposed can quickening material generation embrittlement.
(2) polystyrene foam plate
The intensity of foamed polystyrene board own is not high, and weight capacity is lower, need to strengthen during outer furring brick processing; In addition, will need placement for some time just can use through one period ripening stage when sheet material dispatches from the factory, if the curing time is not enough, the quality of sheet material can not be guaranteed, and panel shrinkage after construction makes system's cracking.
(3) phenolic board
In all organic insulation materials, phenolic board has higher flame retardant resistance.Phenolic board self can reach the flame retardant effect of B1 level.For making its combustionproperty reach the A level, a lot of enterprises take to test to reach the effect that incendivity is the A level behind the composite fire-proof interface again, but are not extensively approved.
The problem of its maximum is that surperficial efflorescence is serious, and is easily aging, and produces hollowing between float coat, and, be exposed to the sun if stand short-term, easily self ftractures.
(4) rock cotton board (bar)
Abroad, rock cotton board is used for the building heat preservation history of existing decades, is that A level lagging material is used the most ripe heat-insulation system at most, and such as Germany, the building that highly surpasses 22 meters uses rock wool as fire-retardant heat-insulation material mostly.And it is domestic, the industrialized level of rock wool is lower, traditional production technique adopts layer spread method more, the interlayer bonding force of product is low, slag content is high, and acidity quotient is low, and water-intake rate is high, only just need to adopt many kinds of measures for making up its anti-pulling undercapacity, such as increase bond area, increase anchoring piece quantity, adopt and double-deckly strengthen web frame, increase the interface processing of rock cotton board etc.
(5) foam cement and foamed glass
Foam cement and multicellular glass belong to inorganic foamed lagging material, have excellent fire line, weather resistance, good interface adhesion, and the theoretical life-span can be identical with buildings.
The thermal conductivity of foam cement can reach 0.045-0.08w/m.k and not wait by adjusting expansion ratio, but for unit weight at 200-270kg/m
3Lagging material, corresponding thermal conductivity should be between 0.06-0.07w/m.k.
Multicellular glass is the material through the high temperature sintering foaming, has higher rate of closed hole, extremely low water-absorbent.Relative foam cement, unit weight is lighter, thermal conductivity is lower, and intensity is slightly high.Unit weight is at 150-180kg/m
3Between the time, thermal conductivity can be controlled in 0.062w/m.k.
Although above bi-material all has outstanding fire line, have the fragility weakness of inorganic materials concurrently, add that thermal conductivity is higher, during dilatational strain, stress concentration easily ftractures in the plate seam, and therefore, the application of foam cement and multicellular glass is extremely restricted.
(6) inorganic heat insulation mortar
The inorganic heat preservation slurry is longer at the applicating history in building heat preservation field, and afterwards along with design standard for energy efficiency of buildings progressively improves, it is because water-intake rate is high, the defective such as heat insulation effect is wayward and progressively making no public appearances.The vitrified micro-bead heat preserving slurry that in inorganic heat insulation mortar, at present performance is preferably take expanded and vitrified small ball as the aggregate mixed cement, the materials such as redispersible powder, anti-crack fiber form, it has higher rate of closed hole, water-intake rate, thermal conductivity and decreases.The thermal conductivity of kervit microbead insulated sand slurry can be controlled in 0.07w/m.k, but compares with the lagging material of efficient organic, also has larger gap.
(7) inorganic-phase variable lagging material
There is dispute in the application of inorganic phase-changing material in the building exterior wall heat preserving field always.It adds a certain proportion of phase change material take inorganic materials as main carriers, constructs and is pressed into Alkali-resisting fiberglass mesh by on-the-spot trowelling, it is said that 40-50mm can realize building energy conservation 65% design requirements, and this is suspectable.According to phase-change mechanism, when surpassing certain temperature, solid-phase is to liquid phase transition, and material absorbs heat; When temperature was down to certain temperature, to solid transformation, the beginning heat release was kept the relatively stable of temperature in certain space by heat absorption and release to material by liquid phase.
But the relevant expert represents, domestic phase change material is applied to exterior-wall heat insulation is irrational.Especially at northern area, winter outdoor temperature on average generally lower than 5 ℃ even 0 ℃, phase change material no longer occurs or is difficult to undergo phase transition, be also towards outdoor release even if undergo phase transition heat release, with to regulate room temp irrelevant.And according to traditional thermal testing method, the thermal conductivity of phase change material is in the 0.10w/m.k left and right, and is more taller than the thermal conductivity of inorganic heat insulation mortar.
In sum, although A level lagging material kind is more, cut both ways, through analysis-by-synthesis, they and large-scale practical application still have a segment distance.

Embodiment
The below is described in further detail the present invention: the invention provides a kind of compound dipping glue for the production of fireproof heated board, this dipping glue comprises following composition: resol, press down flame agent, smoke suppressant, sequestrant, carbonized agent, inorganic adhesive, water-resisting agent, catalyzer, stablizer, wherein resol is primary binder.
For the ease of preparation, transportation and storage, the present invention further is made into mentioned component A component and B component, and wherein the A component comprises: the resol of 50～95 weight parts, less than the water of 50 weight parts, less than the stablizer of 10 weight parts, less than the catalyzer of 10 weight parts; The B component comprises: the water of 50～95 weight parts, less than the catalyzer of 10 weight parts, less than the inorganic adhesive of 10 weight parts, less than the sequestrant of 10 weight parts and carbonized agent, less than 10 weight parts press down the flame agent, less than the smoke suppressant of 10 weight parts, less than the water-resisting agent of 10 weight parts.
Each component principle of work in the present invention:
Press down the flame agent:
Some inorganic salt, such as phosphoric acid salt, borate, tungstate, silicate etc., has the very strong flame effect that presses down, they at high temperature can form the inorganic expansion coating of vitreous state, promote into charcoal, hinder the effusion of volatile fuel, especially when temperature during higher than 300 ℃, some inorganic salt can decompose, and discharges crystal water, plays the effect of oxygen in foaming, heat absorption, cooling and diluent air.On the other hand, decompose the by product that generates and be attached to substrate surface formation tectum, can suppress inflammable gas and produce, also can stop oxidation and pyrolysis.
Smoke suppressant:
Transition metal salt such as tungsten, molybdenum, iron, titanium, manganese or rare earth element etc., has smoke suppressing effect preferably.They at high temperature decompose the water of emitting can absorb heat, plays the effect of cooling dilution; When high temperature, the oxygen acid that oxidation generates covers material surface, accelerates dehydration carbonization, and the liquid film of formation and charcoal layer can separate oxygen, volatile fuel and heat and the inner base material of outside, thereby reaches the purpose of flame-retardant smoke inhibition.
Sequestrant, carbonized agent:
The chemical stability of organic phosphoric acid is good, facile hydrolysis not, the ability comparatively high temps, many metal ions such as calcium, magnesium, copper, zinc there is excellent sequestering power, greatly improve dispersiveness and the cementability of some ceramic phase metal oxides, make its refractory aggregate that becomes fireproof heated board, even transient temperature is too high, its stronger charing ability also can play good fire retardation.
Inorganic adhesive:
Inorganic adhesive is easy to disperse, moulding, in case after solidifying, very strong bonding force is arranged, high temperature resistant, anti-vibration, antistripping, high temperature resistant airflow scouring have good infrared absorbance and insulativity.
Water-resisting agent:
Macromolecule emulsion is easy to disperse, and bonding force is strong, can form hydrophobic film at fiber surface, plays good waterproof action.
Composite catalyst system:
catalyzer can increase the reactive behavior of the functional groups such as resol phenolic hydroxyl group and its place, adjacency pair position, methoxyl group, reduce the solidification value of resol, impel it can be crosslinked as early as possible in the drying and dewatering process, be attached to a greater degree fiber surface, be difficult for escaping with steam when dehydration by evaporation, in addition, the composition metal salt catalyst can also improve the reactive behavior of phenolic hydroxyl group, boride reaction in impelling it and filling a prescription generates the higher boron oxygen key of bond energy, again because having sealed phenolic hydroxyl group, the heat decomposition temperature of boron modified phenolic resin than common resol high 100 ℃～140 ℃, its cured article reaches more than 70% at the carbon yield of 900 ℃, and common phenolic resin curing thing carbon yield at the same temperature is only in 50% left and right, and, because the crosslinking structure that high bond energy chemical bond is arranged exists, generated hard dystectic carbide during high temperature ablation, therefore, the thermotolerance of heat resist modification phenolic aldehyde, instantaneous resistance to elevated temperatures, ablation resistance and mechanical property are all high than common resol.
Stablizer:
Resol has active function groups, all can react curing under the effect of heating or acid.This makes thermosetting resin raise in the storage process medium viscosity, and gelation rate is accelerated, and 10 ℃ of speed of response of the every rising of temperature-averaging will increase by 2～4 times, so resol must be stored under cold condition, could extend its preservation period as far as possible.Therefore, introduce the reactive behavior that stablizer is intended to reduce as much as possible phenolic hydroxyl group and the easy oxidation of methylene radical, simultaneously, block hydrophobic nature, intensity and thermotolerance after phenolic hydroxyl group can also improve resin solidification.
Basalt fibre comes from the volcanics ore, compares with other ore, contains more iron and titanium, and this has given the high-temperature stability of its ultralow thermal conductivity with excellence, is a kind of good fireproof heat insulating base material.
The fireproof heat insulating base material that performance is outstanding is the basis of qualified fireproof heated board, and it must could practical application through further processing.Dipping matrix of the present invention is in resin base caking agent platform, form the coating of intact in basalt fibre surface in production process, the bonding force of solidification process floating coat strengthens gradually, make originally the moulding that is fixed of loose fiber, simultaneously, form a large amount of adhesive spots between fiber, macro-effect is presented as that the physical strength of fireproof heat insulating base material is significantly improved.Moreover, coating itself also possesses excellent fire retardant performance and lower thermal conductivity, does not affect the fireproof heat insulating performance of basalt fibre at all, and can significantly improve its water-repellancy.
Use dipping glue of the present invention to process the fireproof heated board that basalt fibre makes, its properties is all very superior after tested, and this is the keying action that in formula, composite catalyst system plays.On the one hand, it rapidly the common resol of catalysis with the formula in boride be cross-linked to form bond energy than carbon-oxygen-carbon bond (bond energy 334.72kJ/mol
-1) higher carbon-oxygen-boron key (774.04kJ/mol
-1), thereby form the boron modified phenolic resin that has high mechanical strength more and stronger high temperature resistant, more anti-ablation than common resol.
The typical resistance to elevated temperatures of boron modified phenolic resin:
(1) decomposition temperature is more than 500 ℃, and 1000 ℃ still have 50% carbon residue rate.
(2) oxygen index 48.5, do not fire, and is substantially smokelessly nontoxic.
(3) linear ablative rate-0.079mm/s, mass ablative rate 0.0333g/s.
On the other hand, heat labile free phenolic hydroxyl group in further minimizing system of this significant improvement makes high thermal resistance and anti-burning property after resin solidification greatly improve, and is also higher with bonding force and the physical strength of fireproof heat insulating plate substrate.The more important thing is, it not only can greatly reduce the generated time of boron phenolic aldehyde, and we can finely tune the processing condition that it makes each stage in its coupling production fireproof heated board process, with online synthetic being controlled in the production craft step of warming plate of boron resin, on production line, online the synthesizing of synchronously realizing boron modified phenolic resin in the fiber surface treating processes reached other modifications.Thereby formation has the fiber surface coating of high strength, high adhesion, anti-ablation, high carbon residue, fire-retardant, few cigarette, low toxicity, has greatly improved mechanics of machinery and the fire retardant performance of modified fibre goods.
Review the method for conventional synthetic boron bakelite resin, usually need to carry out complex steps in special reactor, by product is many, and time consumption and energy consumption is with high costs, and the preparation boron modified phenolic resin be solid-state, can only be dissolved in organic solvent, workability and property easy to use are very poor.If make the major ingredient of dipping glue with it, must use the organic solvents such as ethanol, cause the process monitor such as security against fire, environmental protection in production, control to get up very complicated, cause simultaneously the organic pollutant discharging to increase and greatly increase cost.And be water-based with the dipping glue of formula of the present invention preparation, in use procedure as required thin up adjust concentration, needn't use and easily bring organic solvent dangerous and that pollute.Easy to use, production process is controlled simply, pollutant emission is few, with low cost.Compare with other resin base dipping glue, the present invention is outstanding in high temperature resistant, the anti-performance of burning of coating that fiber surface forms, combustion hardly, smokeless under high temperature, and also thermal conductivity is low, the sheet material that makes has outstanding fireproof heat insulating performance, can reach the fire-protection standard of A1 level.
