Technical field
The present invention relates to a kind of coagulation material for building and decorating, particularly a kind of magnesite coagulation material and the composition board made with this material.
Background technology
Existing for build and decorate magnesite material generally mainly by magnesium oxide and magnesium chloride solution, mixed, for example: magnesia cement, it is by the magnesia of producing through roasting giobertite, the compositions such as magnesium chloride solution.The building made from magnesite material or dalle, there is intensity high (ultimate compression strength >=60MPa), good flame resistance (thermotolerance/℃ > 300), resistance to flame (A level is not fired), good (good being bonded together of object energy that slurry is in contact with it in process of setting of agglutinating value(of coal), there is good agglutinating value(of coal)) and the advantage such as water-tolerant (finished product of slurry induration after complete coagulation forming is water-fast, is good water-resistant material).But the magnesia cement goods that use at present but exist following deficiency:
1, fragility is large: although slurry induration intensity is high, easily crisp.
2, water resisting property is poor: the microstate of slurry induration is by fine shape crystal composition, and between crystal, space is very easily immersed and caused the destruction to crystalline structure by water, thereby affects weather resistance and the freeze-thaw resistance of slurry induration.
3, easily return halogen and play tide: thus in slurry induration, because very easily existing the chlorion of free state to cause to return halogen, proportioning problem plays damp phenomenon, and this phenomenon has a strong impact on the use of slurry induration.
4, in condensing process, very easily produce distortion: in the condensation cure process of slurry induration, will discharge a large amount of heats, this exothermic process is a large amount of concentrate on several or tens hours in, this heat can make slurry induration in exothermic process, produce expansion, after exothermic process completes, slurry induration is along with the process that normality produces again a contraction that drops to of temperature, such one swollen one receives, and makes slurry induration finished product produce larger distortion.
5, weight is still larger, belongs to non-light material: after slurry condensation cure, the density of induration is about: 2200kg/m 3.
Relevant technologies personnel also useful polystyrene material jointly use together with magnesite material, for example: in CN201169862Y, disclose the utility model patent that a kind of name is called " Modified magnesite polyphenyl composite wall plate ", wallboard described in this patent is mainly to consist of wallboard outer wall and wallboard core, wherein, wallboard outer wall is to consist of magnesite material, wallboard core is to consist of polystyrene material, and wallboard outer wall is being coated the simple monoblock wallboard core consisting of polystyrene material of monoblock completely.Although this patent takes full advantage of the light material that polystyrene has, (density of granular polystyrene is very light, general≤15.0kg/m 3), water-intake rate is low (because the granule interior of granular polystyrene is unicellular structure, so its water-intake rate is low especially), flexible resilient is good (under the effect of non-destruction external force, once tear the external force that disappears open, granular polystyrene can recover former state substantially), lower temperature resistance and the advantage such as freeze-thaw resistance is good, but, the above-mentioned deficiency that it has except magnesite itself can not overcome, once wallboard outer wall is because of distortion or other reason appearance breakage, its structure will be destroyed completely, and exists following deficiency:
1, belong to inflammable material: granular polystyrene chance fire shrinks burning is typical inflammable material.
2, non-refractory: granular polystyrene starts fusing when temperature >=120 ℃ starts to shrink burning when reaching burning-point.
3, intensity is low: ultimate compression strength < 0.5 MPa of granular polystyrene.

2, good heat-proof quality: take magnesium oxide, magnesium chloride as the heat-conduction coefficient of the slurry induration that main raw material is made itself is just lower, be generally 0.258W/ (mK); The heat-conduction coefficient of granular polystyrene is lower, be generally 0.06W/ (mK), because slurry induration in coagulation material accounts for ratio≤40% of cumulative volume, so the thermal conduction of coagulation material of the present invention must be significantly to reduce, generally at 0.08W/ (mK)～0.20W/ (mK).
3, good sound-proofing properties: because granular polystyrene in coagulation material accounts for ratio >=60% of cumulative volume, can bring into play well the sound absorption qualities that granular polystyrene is good, compare with existing magnesite material, coagulation material sound-proofing properties of the present invention significantly improves.
4, good flame retardant resistance: magnesite slurry induration itself is exactly a kind of superior inorganic anti-flaming material, in the inside of coagulation material, slurry induration is by tight being wrapped in induration of granular polystyrene, granular polystyrene and fiery contacting have effectively been completely cut off, at coagulation material, will not produce naked light by naked light calcination in the situation that, just be subject to the granular polystyrene of fiery face part at high temperature to produce gasification, leave slurry induration shell, make the inner part corresponding with being subject to fiery face of coagulation material become honeycomb poroid, and the structure of other parts does not change, from one-piece construction, profile still remains intact, the poroid fixed physical efficiency of magnesite slurry of local one-tenth honeycomb stops heat inwardly to be transmitted well, avoid the temperature of coagulation material inside further to raise, thereby protected granular polystyrene, prevented more profound granular polystyrene gasification, realized fire-retardant object completely, so, coagulation material of the present invention has good flame retardant resistance.
5, good strength: although the ratio that in coagulation material, granular polystyrene accounts for is large, but because the ultimate compression strength of slurry induration is high, parting face by finished product can be found out, slurry forms the poroid support frame of honeycomb between granular polystyrene, thereby make coagulation material possess higher intensity, compare with existing magnesite material, although ultimate compression strength decreases, generally, the ultimate compression strength of coagulation material of the present invention is 1MPa～150MPa, can be according to the actual needs, produce the coagulation material of corresponding ultimate compression strength, be used as lagging material for building and materials for wall, can meet technical requirements completely.
6, the present invention is widely used, and has extremely strong practicality:
(1), can be by the present invention the coagulation material before solidifying, thickness according to actual needs or width, arbitrarily directly cast-in-place being laid on flooring, ground, roofing or as smearing mortar smeared on the wall, becomes the cast-in-place material of insulation with fire-proof function.
