Description
Technical field:
The present invention relates to a kind of material of construction, be meant a kind of heat-insulating fireproof mortar that utilizes glass bead to replace traditional mortar aggregate especially.
Background technology:
There is certain relation in the effect difference of different starting material in dry-mixed mortar between the component of dry-mixed mortar and performance.Wherein, light filler-stomach material such as pearlstone, expanded vermiculite etc. can alleviate the density of mortar, improve its heat-insulating property, cause people's attention.At present, energy-conservation necessity impels people to seek the aglite that can add mortar and plastering material, to improve the heat-insulating property of these products.Traditional masonry mortar and motar in use manifest defective, and it is from great, and heat-insulating property is poor, use the back easily to produce crack etc.It is a lot of to cause that body of wall produces fissured factor, wherein, the stress that is produced by the temperature difference also is to cause body of wall to produce one of reasons of cracks, (body of wall shrink stress that the stress, masonry mortar and the plastering material that produce produce and the stress that produced by the temperature difference or the like) gathers together if all stress, add mortar material defective really up to the mark, may cause the generation of body of wall large fracture.For light block, the heat-insulating property of its masonry mortar and plastering material must be better than the heat-insulating property of building block, promptly so-called " the soft face in the hard end ", mean on metope coat of plaster more outward intensity should a little less than or the foundation base intension that contacted with it at most consistent, with respect to light block, suitable mortar only may be the light mortar that is complementary with it.And the distinctive heat-insulating property of these light mortars has been avoided so-called " cold bridge " effect, has reduced fissured generation.
In steel and concrete structure, not load-bearing of middle wall body, therefore the masonry mortar and the motar of construction use needn't have very high ultimate compression strength.Can make masonry mortar and plastering material reach its highest attainable heat-insulating property as far as possible thus.In addition, use heavy, do not contain pore plaster and masonry mortar is difficult to realize desirable and suitable temperature field, space.Be difficult to prevent that warm room is with respect to ice-cold staircase or there is not the heat in the room of heating to run off.Although outer insulation can improve the thermal and insulating performance of building, reach energy-conservation.But the heat in the room that prevents to warm oneself is to the heat loss no less important of contiguous room of not warming oneself or staircase.Thermal insulation mortar and plastering material have certain advantage here, can bring certain energy-saving effect, and the comfort level of Ju Zhuing has also obtained certain raising simultaneously.The process of heating is exactly the temperature that increases in the room, and the temperature difference of necessary balance room temp and interior wall temperature.If the interior wall temperature is low, just need to consume big energy.If interior wall temperature and indoor air temperature are close, energy needed is just few.High interior wall temperature just can realize higher residence comfort, is not more than 3% difference variation because people's health can only be experienced.If interior wall has used the interior wall plastering mortar of insulation, the temperature difference of interior wall temperature and indoor air temperature is just less than 3%, and what people experienced is same temperature, that is to say that residence comfort has improved.
Be the heat-insulating property of realization masonry mortar and plastering material, and don't wish when mixing, to produce bubble, will use aglite.At present, traditional aglite mainly contains pearlstone and expanded vermiculite, but there is the defective of essence in these two kinds of aglites with regard to the state after the present expansion: at present, in the pearlstone production process, lose crystal water after the ore in sand form raw material is heated at a certain temperature, then expand.But the vapor pressure that too high temperature produces crystal water bursts material surface, although it is very light to form the porous expanding material thus, has heat insulation function, but because of its porous surface, in the time of in using masonry mortar and plastering material, moisture content during stirring can immerse the hollow structure of pearlstone with gelling material, fill its cavity, loses its heat insulation effect after making the material drying.Especially in the whipping process of machine mixer, pearlstone destructurized causes volume-diminished and further causes the loss of heat insulation effect.In addition, because the surface-area of expanded perlite granule is bigger, need add a large amount of mixing waters during use, can make mortar that the loss of strength of (relevant with churning time) is arranged after drying in various degree with plastering material, this is the another shortcoming of pearlstone.Therefore, do not allow at the mechanical execution of European scope perlite mortar and plastering material.
Different with pearlstone, vermiculite can spalling in the expansible process.Vermiculite is a kind of magniferous water aluminium silicate mineral of laminate structure, and its crystal water is between the laminate structure unit, and in vermiculite ore in sand form heat-processed, vapor pressure makes material separated from one another along the laminate structure direction, causes volumetric expansion.Because of under the effect of vapor pressure, gravitation between the laminate structure separated from one another lose substantially or a little less than, when making material join in mortar and the plastering material, under the effect of the mechanical stirring power and the stirring aqueous solution, peel off along the generation of laminate structure direction, cause the expanded vermiculite structure deteriorate, so just lost the heat insulation effect of this aglite.In addition, foregoing pearlstone mixing water causes that the problem of dry back loss of strength exists too in expanded vermiculite.Above-mentioned two kinds of aglite common shortcomings are, can produce a large amount of ducts in a large amount of mixing water evaporative drying processes, and this causes a large amount of suctions in later stage possibly, reduces the frost resistance of material, makes mortar and plastering material under the situation of enduring cold destroyed.
Glass bead is a kind of unorganic glass matter mineral material; process through the special producing Technology; be irregular spherule particle; inner porous air cavity configuration; surface vitreous sealing, gloss is level and smooth, and physicochemical property is stable; have light weight, thermal insulation, fire prevention, high-low temperature resistant, anti-aging, excellent specific property, the application of many traditional lightweight aggregates in different goods such as alternative fly ash float, glass microballon, pearlstone, granular polystyrene such as water-intake rate is little.
Summary of the invention:
The invention provides and a kind ofly replace traditional mortar aggregate with glass bead; the method of preparation heat-insulating fireproof mortar in construction work; utilize glass bead light weight, thermal insulation, fire prevention, high-low temperature resistant, anti-aging, excellent specific property such as water-intake rate is little, can solve the problems of using traditional aggregate to bring effectively.
Purpose of the present invention is achieved through the following technical solutions:
A kind of glass micro bead heat insulating fire proof grout, include glass bead and dry powder additive, with the aglite of glass bead as dry-mixed mortar, premixing is among dry powder additive, form single-component inorganic dry powder thermal insulation mortar, site operation adds water and stirs and can use; Described dry powder additive is a dry powder properties-correcting agent; Described glass bead shared volume ratio in mortar is 50%～95%; The accumulation unit weight of described glass bead is 60～100 kilograms/cubic metre; The granularity of described glass bead is that scope is 0.5～1.5mm; The thermal conductivity of described glass bead is 0.032～0.045w/m.k; The refractoriness of described glass bead is 1000～1200 ℃.
