Description
Technical field
The invention belongs to building decoration technology field, more particularly to a kind of very-high performance with automatically cleaning photo-catalysis function
Concrete decorated hanging board and its manufacture craft.
Background technology
As the pollution of urban air environment is increasingly severe, the ornament materials of external wall receives large effect.
Part stone curtain wall and exterior wall finish plate are poor due to surface resistance to soiling, and the air of the pollution directly durability degree attractive in appearance to its is formed
Influence, causes its clean and maintenance burden in the future.At present, on the exterior wall of the high-end building in part, photocatalytic self-cleaning is used
Material is to solve this problem.Such as stone curtain wall and Decorative hanging board are after photocatalytic self-cleaning material has been used, its surface resistance to soiling
Greatly enhance, at the same can also in the presence of illumination purifying contaminated air so that building coat is in " go out mud without dye "
Positive effect can also be produced to environment simultaneously.But above-mentioned application there is also some letters it is to be solved the problem of, such as due to automatically cleaning
Matrix accompanying by catalysis material is not firm enough (such as stone surface peeling), or weather resistance be present (as applied
Expect that UV resistant is poor) etc., cause its durability not enough, usual 3-5 just loses effect.
The content of the invention
It is an object of the invention to provide a kind of ultra-high performance concrete Decorative hanging board with automatically cleaning photo-catalysis function and
Its manufacture craft, by using ultra-high performance concrete as the light-catalysed carrier of automatically cleaning, and uses special process so that from
The functioning efficiency and durability for cleaning catalysis material are greatly improved.
The technical solution adopted by the present invention is as follows：
A kind of ultra-high performance concrete Decorative hanging board with automatically cleaning photo-catalysis function, is obtained by following techniques：With
Ultra-high performance concrete is the base material of Decorative hanging board, make it that the exposure of ultra-high performance concrete surface is husky by exposed on surface material technique
Stone aggregate obtains rough surface, and then being obtained in rough surface spraying automatically cleaning catalysis material has automatically cleaning photo-catalysis function
Ultra-high performance concrete Decorative hanging board.
Wherein, its volume 0.5-1.6% glass fibre, stainless steel fibre are added with ultra-high performance concrete dry blend
Or basalt fibre.
Specifically, step is as follows：
1) die surface after the cleaning adheres to solvent-borne type surface retarders and treats that its is dried；
2) ultra-high performance concrete slurry is prepared, and it is equal to add glass fibre, stainless steel fibre or basalt fibre stirring
It is even, after-pouring in mould and cause surfacing；
3) ultra-high performance concrete in mould is conserved, taken off when reaching 40MPa-50MPa to compression strength
Mould；
4) cement slurry of the very-high performance plaque surface after the demoulding is removed using high pressure, until cement can not be removed
Untill slurry, so as to expose aggregate and fiber, dry afterwards；
5) in step 4) obtained plaque surface even application automatically cleaning catalysis material, dry complete afterwards
Decorative hanging board.
Described mould is preferably PVC wood plastic formwork or steel template.
Step 1) in, described solvent-borne type surface retarders model is preferably RECKLI CR TYPE N/02.
Described solvent-borne type surface retarders consumption is 150-250g/m2, preferably 200g/m2。
Step 2) in, when preparing ultra-high performance concrete slurry, as far as possible from fine aggregate, maximum aggregate size is no more than
1mm。
Step 5) in, the consumption of automatically cleaning catalysis material is 20-100g/m2.Specifically can be according to the thick of plaque surface
Rough degree is adjusted.
Ultra-high performance concrete compression strength produced by the present invention is 100-150MPa.
Wherein, the present invention uses solvent-borne type surface retarders so that UHPC Decorative hanging boards surface has more attractive in appearance undisguised
Expect effect and highly uniform undisguised material depth.It plays a part of hindering the hardening of concrete surface slurry in the present invention, its
Depth of interaction only has very thin one layer, has no effect on the aquation of inside concrete cement, thus does not influence its structural strength, only meeting
So that the aggregate on surface is exposed.
Addition fiber can improve the shock resistance, resistance to compression, fracture resistence force intensity of UHPC decorative panels, while the fiber of exposure is also
There is provided huge surface area so that the automatically cleaning catalysis material of attachment thereon has more preferable effect.
Curing strength reflects the degree of inside concrete hydrated cementitious from side, and degree of hydration then affects surface slow setting
Depth of the agent to concrete surface slow setting.Curing strength is lower, and slow setting depth is deeper, and curing strength is higher, and slow setting is more shallow.Through hair
Person of good sense's experimental verification, is rushed when curing strength reaches 40-50MPa using giant to the plaque surface after the demoulding
Wash, undisguised material effect and slow setting depth well can be reached so that aggregate and fiber in UHPC matrixes can be obtained necessarily
The exposure of amount, so as to allow automatically cleaning catalysis material stably to adhere to using huge surface area, is substantially utilized
The huge surface area of Decorative hanging board, greatly promotes the reaction efficiency of automatically cleaning catalysis material.
The present invention compared with prior art, has the following advantages that：
The ultra-high performance concrete Decorative hanging board with high-efficiency self-cleaning photo-catalysis function of the present invention, it uses superelevation
Energy concrete (hereinafter referred to as UHPC) passes through exposed on surface material technique as the base material of Decorative hanging board so that UHPC surfaces expose
Sandstone aggregate, with rougher surface.On the other hand, it is fine by mixing a certain amount of glass fibre, stainless steel inside UHPC
Dimension or basalt fibre, after undisguised material technique, glass fibre, stainless steel fibre or basalt fibre in UHPC matrixes
A certain amount of exposure can be obtained so that the surface area of Decorative hanging board is huge, after its surface spraying automatically cleaning catalysis material, made
Exposed aggregate and fiber surface can be stably adhered to derived from cleaning catalysis material, substantially can be hung using decoration
The huge surface area of plate, greatly promotes the reaction efficiency of automatically cleaning catalysis material.In addition, UHPC has the intensity of superelevation and resistance to
Hou Xing, extremely low water absorption rate is also not in freeze-thaw damage, the load of such superior performance under exceedingly odious environment
Body so that therefore the automatically cleaning catalysis material of its surface attachment also obtains higher durability.
Brief description of the drawings
Fig. 1 is the schematic diagram on different retarding effect surfaces, and its middle and upper part is divided into the deeper surface of slow setting, and bottom is divided into slow setting
Shallower surface, centre is the normal concrete surface of non-slow setting.It can be seen that whether slow setting is deeper or shallower
Surface, the normal concrete surface relative to non-slow setting suffers from undisguised material effect well, and with slow setting degree plus
Deep, undisguised material effect is more notable；Meanwhile, it can be seen that Fig. 1 upper part and lower part all have good slow setting
Depth, especially on the deeper surface of slow setting, slow setting depth is also more unified, and is conducive to the attachment of automatically cleaning catalysis material.
