Description

Sandwiched mortar heat-insulating/warm-keeping block and preparation and application thereof
Technical field
The present invention relates to a kind of construction material, particularly a kind of Sandwiched mortar heat-insulating/warm-keeping block and preparation and application thereof with energy-conserving and environment-protective heat-insulation and heat-preservation, sound insulation sound-absorbing and fire-proof function.
Background technology
In the prior art, energy-saving building materials with heat insulation and preservation effect, mostly be to paste or smear and whitewash on the wall body outer wall face, As time goes on, expose to wind and rain, expose to the sun and rain and the effect of seasonal variations etc. through long-term, these materials can change, and expand with heat and contract with cold to cause that irregular be full of cracks infiltration occurs wall covering, loses original heat-insulation and heat-preservation function.Simultaneously, the aging of wall plaster layer comes off, and not only affects attractive in appearancely, also can cause potential safety hazard.Disclose a kind of glue powder polyphenyl particle such as Chinese invention patent 02153345.8 and be incubated wall tile wall on heat and job practices thereof outward, it is the body of wall outside spraying glue powder polyphenyl particle slurry insulation layer that is building up, outside at insulation layer arranges the overcoats such as anti-crack polymer cement mortar layer, gauze wire cloth and face brick again, although this structure can effectively prevent cracking and come off, and exists construction inconvenience, long construction period, high cost defective.
Chinese invention patent 02124522.3 discloses light-weight small building block as sandwich of wall and production method thereof, the clamping plate internal layer of this sandwich building block is completely enclosed within the cement surface layer, therefore the body of wall that is built into by this sandwich building block exists obvious heat bridge effect at the puzzle joint place, and the effect of heat-insulation and heat-preservation is not fine.
Chinese invention patent 00134571.0 discloses a kind of concrete bearing wall bluk recombination heat insulating hollow building block and production method, this heat insulating hollow building block comprises exterior trim surface layer, insulation layer, contact pin and load bearing hollow block, insulation layer is made of the self-extinguishing type polyphenyl plate, insulation layer and links together by contact pin, cementing agent and cement etc. between finish coat and load bearing hollow block.But the combination between this each layer of structure is not very firm, when transportation or use fault-layer-phenomenon occurs easily, causes and uses inconvenience or affect result of use.
Summary of the invention
The technical problem that the present invention will solve provides a kind of Sandwiched mortar heat-insulating/warm-keeping block, to overcome the defects of prior art.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of Sandwiched mortar heat-insulating/warm-keeping block, there is the thermal insulation separation thermosphere in building block central authorities, are the glue sand concrete in the both sides of thermal insulation separation thermosphere, with thermal insulation separation thermosphere and glue sand concrete vibration extrusion forming.Better, contain compound additive in the raw material of described thermal insulation separation thermosphere.
Consisting of of described compound additive: rosin 17-26wt%, peregal 2-9wt%, surplus is water.
The preparation method of compound additive is: rosin heating fusing becomes emulsus to get final product with rosin, peregal and the water of fusing are miscible in proportion.
The addition of compound additive is the 0.1-2% of cement quality in the thermal insulation separation thermosphere raw materials in the thermal insulation separation thermosphere.

Except compound additive, the raw materials of all the other thermal insulation separation thermospheres is routine, as comprises heat insulating material, cement and compound additive, also can use some additives commonly used etc.Described cement preference modification silicate cement.The ratio of the raw materials such as described heat insulating material and cement is selected conventional.Preferably, take the raw material gross weight of thermal insulation separation thermosphere as the basis, the raw materials of the raw materials of thermal insulation separation thermosphere comprises: heat insulating material 79-95wt%, cement 4-20wt%, compound additive are 0.01-0.4wt%.The thermal insulation separation thermosphere is to be cast in the model by the mixed slurry that each raw material and water are mixed with, and obtains through natural curing.
Described heat insulating material can be selected from: any in organic granular polystyrene, hydrophobic rock wool particle and the hydrophobic pearlite particle.
The raw materials of glue sand concrete is routine, as comprises cement and aggregate chips, also optionally adds some additives commonly used such as early strength admixture etc.The ratio of the raw materials such as described cement and aggregate chips is selected conventional.Preferably, take the raw material gross weight of glue sand concrete as the basis, the raw materials of glue sand concrete comprises: cement, aggregate chips and stone, also can comprise the inorganics such as flyash, grey calcium powder, calcium silicates, and its ratio adopts conventional concrete ratio.
Preferably, also be added with complex accelerator in the raw materials of heat-insulation and heat-preservation building block of the present invention.
The addition of complex accelerator is the 0.1-2% of cement quality in the glue sand concrete.
Complex accelerator adopts the compound organic amine Admixture of inorganic salts, and the morning of mainly accelerating building block is strong, is that the turnover operating period of pallet shortens, and reduces the cost of production of building block.Better, the raw material of complex accelerator consists of: triethanolamine 0.01-0.08wt%, and sodium chloride 0.01-1wt%, surplus is water; Or raw material consists of: salt 0.3-1.0wt% or triethanolamine 0.01-0.08wt%, and sodium sulphate 1.0-2.5wt%, dihydrate gypsum 1.0-3.0wt%, surplus is water.In proportion with triethanolamine, sodium chloride and water miscible both described complex accelerator.
Better, described glue sand concrete is provided with a plurality of through holes.As be provided with the vertical hole more than 2 that communicates up and down.
The profile of building block can be the universal building-block shapes such as cuboid or square, also can produce according to the user's request mfg. moulding die, also can be provided with the structures such as groove, horizontal bar in the heat-insulation and heat-preservation building block.
Better, described glue sand concrete and thermal insulation separation thermosphere are also by dovetail groove and the interlock of dovetail tooth.
Building block of the present invention prepares by following method:
1) preparation of thermal insulation separation thermosphere: the mixed slurry that will prepare take heat insulating material, cement and compound additive as raw material is poured in the pattern of thermal insulation separation thermosphere, after the demoulding maintenance, forms described thermal insulation separation thermosphere;
2) preparation of glue sand concrete: with each raw material mixed preparing glue sand concrete in proportion;
3) thermal insulation separation thermosphere and glue sand concrete is compound: the thermal insulation separation thermosphere is placed on the laminboard layer position of building block model, then the glue sand concrete is cast in the both sides of thermal insulation separation thermosphere in the building block model, through the extrusion forming of vibrating.Better, more than both sides pressurization 10MPa.
4) after the demoulding maintenance, be finished product.
Sandwiched mortar heat-insulating/warm-keeping block of the present invention can be used for making the materials for wall of various buildings.
The invention has the beneficial effects as follows: building block glue sand concrete of the present invention and thermal insulation interlayer are compound firmly, difficult drop-off, the building block durable that makes, with the body of wall coexistence, having fabulous heat insulation and preservation effect is a kind of energy-conserving and environment-protective fireproof novel wall material.
