Enough it is provided simultaneously with heat preservation and fire protecting performance.
Detailed description of the invention
Fig. 1 is the sectional side view for the outer curtain wall composite plate that the embodiment of the present invention proposes.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
As shown in Figure 1, the embodiment of the present invention proposes a kind of outer curtain wall composite plate, including surface layer 1, lightgage steel joist 2 and company
Connect layer 3；
The surface layer 1 is aluminum base plate；
The surface layer 1 and the articulamentum 3 are separately positioned on the two sides of the lightgage steel joist 2, enclose with the lightgage steel joist
Cavity is synthesized, is filled with insulating layer in the cavity；The insulating layer is put together by more vertical hair rock wool boards 4, the vertical hair
Upper and lower surface of the machine direction of rock wool board perpendicular to the insulation board；The outer surface of the vertical hair rock wool board is coated with inorganic heat preservation
Mortar 5 simultaneously covers first layer alkali resistant glass fibre open weave cloth, is coated with cement mortar 6 on the first layer alkali resistant glass fibre open weave cloth；It is described
Second layer alkali resistant glass fibre open weave cloth is equipped in cement mortar 6, second layer alkali resistant glass fibre open weave cloth surface is coated with the water
Cement mortar 6.
As it can be seen that the outer curtain wall composite plate that the embodiment of the present invention proposes, the heat transfer coefficient of vertical hair rock wool board is lower, can satisfy
The requirement of heat preservation；By mentioning oily inorganic heat insulation mortar in the outer surface of vertical hair rock wool board, the waterproof of vertical hair rock wool board can be enhanced
Performance, so as to be provided simultaneously with heat preservation and fire protecting performance.
In a preferred embodiment of the invention, the aluminum base plate surface is coated with fluororine-carbon coating.
Fluorocarbon coating refers to the coating using fluororesin as main film forming substance；Also known as F-C paint, fluoro coatings, fluorine resin coating
Deng.Among various coating, for fluorine resin coating since the fluorine element electronegativity of introducing is big, carbon-fluorine bond can be strong, has especially advantageous
Properties.Weatherability, heat resistance, lower temperature resistance, chemical resistance, and there is unique non-stick and low friction
Property.
There is fluorocarbon coating excellent Corrosion Protection can provide protective barrier for aluminum base plate；And its surface hardness
Height, impact resistance, anti-buckling, wearability are good, show splendid physical mechanical property；It has extremely low surface energy, surface simultaneously
Dust can be self-cleaning by rainwater, fabulous hydrophobicity (maximum water absorption rate is less than 5%) and reprimand oil, minimum coefficient of friction
(0.15-0.17), will not non-dust absorption and non-fouling, soil resistance is good；The attachment that fluorocarbon coating all has its excellent on the surface of aluminum base plate
Power.
In a preferred embodiment of the invention, mixed with flyash in the cement mortar, the flyash is described
Mass fraction in cement mortar is 15%-25%.
Flyash has pozzolanic activity, can occur " pozzolanic reaction " with alkaline matter, generates cementaceous hydrated adhesive condensate
Matter.As cement or when admixture, water-reducing effect is significant, be effectively improved concrete workability, increase resistance to compression and bending resistance is strong
Spend, improve impervious and slushing oil, at the same have reduce bleeding and isolation, reduce it is permeable and leaching, reduce early stage and later period drying shrinkage,
Reduce the heat of hydration and drying shrinkage and other effects.
By mixing flyash in cement mortar, the intensity of cement mortar can be improved.
In a preferred embodiment of the invention, mixed with hydrophober in the inorganic heat insulation mortar.
Inorganic heat insulation mortar is covered on the outer surface of vertical hair rock wool board, by mixing hydrophober in inorganic heat insulation mortar,
It can make inorganic heat insulation mortar layer (3~5mm of thickness) that there is hydrophobic effect.Even if vertical hair rock wool board hydrophobicity only has 30%,
Short time impregnates water absorption rate and hydrophobic rate all doubles up.
In a preferred embodiment of the invention, the lower section of the lightgage steel joist is equipped with right angle support frame, the right angle
Support frame side is bolted on the lightgage steel joist, and the other end is equipped with anchor bolt.
In the present embodiment, by the way that right angle support frame is arranged in the lower section of lightgage steel joist, it can be provided for outer curtain wall composite plate
Supporting role.
In a preferred embodiment of the invention, the density of the vertical hair rock wool board is 90Kg/m3.
With the increase of rock wool density, the surface tensile strength of vertical hair rock wool board also be will increase, when core material rock wool density is
90Kg/m3When, the surface tensile strength of vertical hair rock wool-steel plywood can reach 0.14MPa or more, can satisfy exterior-wall heat insulation completely
The requirement of plate.Therefore can choose using density is 90kg/m3Core material of the vertical hair rock wool as vertical hair rock wool board.
In conclusion following effect at least may be implemented in the embodiment of the present invention：
In embodiments of the present invention, the heat transfer coefficient of vertical hair rock wool board is lower, can satisfy the requirement of heat preservation；By perpendicular
The outer surface of silk rock wool board mentions oily inorganic heat insulation mortar, can be protected with the waterproof performance of vertical hair rock wool board so as to be provided simultaneously with
Mild fire protecting performance.
In the present invention in embodiment, since the core material string diameter of vertical hair rock wool board is in vertical array perpendicular to plate face, by rock wool
Silk changes the Direction of fibre distribution of rock wool perpendicular to metope, to change the Impact direction and the direction of motion of fiber, changes
The physical performance index of rock wool.It fundamentally solves the problems, such as fiber fractionation, dilatancy, while significantly enhancing anti-
Tensile strength.After the compound alkaline-resisting grid cloth cladding of inorganic thermal insulation slurry, the tensile strength of face sheet material is up to 0.10MPa, is
13 times of common rock wool.
In embodiments of the present invention, vertical hair rock wool board is coated by the four sides of grid cloth composite protective mortar, General Promotion
The various physical performance indexs of rock wool board.
In embodiments of the present invention, by mixing flyash in cement mortar, the intensity of cement mortar can be improved.
It in embodiments of the present invention, can be compound for outer curtain wall by the way that right angle support frame is arranged in the lower section of lightgage steel joist
Plate provides a supporting role.
In embodiments of the present invention, vertical hair rock wool board is reinforced by using the double-deck glass fiber reticular cloth, vertical hair rock wool can be made
There is plate preferable resistance to split effect, and can significantly improve its shearing strength.
Finally, it should be noted that：The foregoing is merely presently preferred embodiments of the present invention, is merely to illustrate skill of the invention
Art scheme, is not intended to limit the scope of the present invention.Any modification for being made all within the spirits and principles of the present invention,
Equivalent replacement, improvement etc., are included within the scope of protection of the present invention.
