The imitative curtain wall coating series of synthetic resin is in the construction technology of building surface
Technical field
The present invention relates to a kind of construction technology of building coating, the imitative curtain wall coating series of particularly a kind of synthetic resin is in the construction technology of building surface.
Background technology
At present the decorative effect of building surface is more single, is plane effect mostly, and reason is that construction technology is fairly simple, remains traditional " two sides, an end ", promptly brushes one priming paint and twice finish paint, can not satisfy the new demand of modern building incrustation.
Summary of the invention
It is more single to the objective of the invention is to solve in the prior art decorative effect of building surface, be plane effect mostly, reason is that construction technology is fairly simple, remain traditional " two sides, an end ", promptly brush one priming paint and twice finish paint, can not satisfy the problem of the new demand of modern building incrustation, a kind of construction technology that can be used for the building surface application is provided, reach curtain wall decoration effects such as approximate stone material, minute surface, aluminium sheet and wood grain.The present invention designs the construction technology of the imitative curtain wall coating series of synthetic resin at building surface, it is characterized in that: more than 5 ℃, relative humidity is less than being made of the following step under 75% the execution conditions, and (1) basal plane is handled:
1, with the flatness of long guiding ruler scrutiny metope, obvious concavo-convex position is marked with crayon,
2, the part that hole is arranged or significantly cave in is repaired with cement mortar or building special putty,

2, granted full infiltration special putty one, about thickness 1mm, the glass fiber mesh that tiles is then used the plasterer's trowel compacting, and glass fiber mesh is connected with basic unit connects, and then the special putty of granted full infiltration in the above is together,
3, after the shop hung glass fiber mesh, be fine more than 12 hours drying time,
(3) the lattice seaming and cutting are cut
1, width is the dividing joint of 2.0cm, require to eject position line with the line of ink marker,
2, cut dividing joint with cutting machine along position line, depth of cut is 1.5cm,
3, with tool hammer and cutter, will stitch stamen and dig up, with the both sides equating of seam,
(4) infiltration special putty construction
1, after the first pass granted full, with floating rule each piece is struck off from the bottom to top, slightly to be dried after, be fine 3~4 hours drying time, and careful sand milling is removed the scratch seal, after second time granted full, with floating rule each piece is struck off from left to right, more than 80# sand paper or grinding wheel construction are used in polishing, after the 3rd time granted full, be closed flat with a batch of knives, be fine 3~4 hours drying time, with the careful sand milling of the above sand paper of 120#, remove batch cutter seal and lapping defect
1, finish all over infiltration special putty construction after, the watering maintenance, each maintenance interval 4 hours, basal plane flatness≤1mm/2m, the surface does not have obviously and batch to scrape impression, no dry linting phenomenon,
(5) dividing joint is filled
1, elastomeric material Pasteur powder: Pasteur's glue=3: 1,
2, fill before, stitch stamen with water-wet earlier, the slurry for preparing is inserted the seam stamen after, dry about 5 minutes, haul out circular-arc moulding with diameter 2.5cm or slightly big pipe on the joint sealing material surface,
(6) repair the special putty construction
When 1, special putty is repaired in allotment, must adopt electronic stirring,
2, after the granted full, be closed flat with a batch of knives, slightly to be dried after, be fine 3~4 hours drying time, with the careful sand milling of the above sand paper of 120#, remove batch cutter and print and lapping defect,
3, after construction is finished, when turning white, drying gets final product sand milling, watering maintenance, twice maintenance 4 hours at interval, and the maintenance number of times is no less than 4 times, flatness≤0.5mm/2m, surface smoothing is scraped impression for no any batch, and dry 48 hours, clear up the lattice seam at any time,
(7) construction of polishing special putty
When 1, special putty is polished in allotment, need stir with electric hand drill,
2, after the granted full, be closed flat with a batch of knives, after the drying, with the above sand paper sand milling of 280#, behind the sand milling, use the rag dedusting, flatness≤0.3mm/2m, smooth surface is scraped impression for no any batch,
(8) construct with bad oxygen alkali resistant priming paint or other solvent bottom paint of high adhesion force
1, spraying, as seen the putty layer surface forms films, no drain spray phenomenon,
2, be fine 24 hours drying time,
(9) be coated with in the spraying
1, behind the imitative curtain wall middle coating intermediate of deployed synthetic resin, filter with 200 order gauzes, must constantly stir in the put procedure, in order to avoid precipitation,
2, spraying, after dry 12 hours, with the above sand paper sand milling of 400#, sand milling must be thoroughly conscientious, but be coated with in can not be worn out, behind the sand milling, must use the rag dedusting,
(10) spray-coating surface is coated with
1, after the imitative curtain wall coating of deployed synthetic resin, filter with 200 order gauzes, must constantly stir in the put procedure, in order to avoid precipitation,
2, spraying is evenly distributed, and dry 24 hours then,
(11) the lattice seam is retouched and is coated with
Brush, post protection with U.S. line paper self-adhesive tape along stitching both sides, brush the lattice pigmented finiss twice, slightly to be dried after, tear U.S. line paper off.
Advantage of the present invention is the construction technology that can be used for the building surface application, reaches curtain wall decoration effects such as approximate stone material, minute surface, aluminium sheet and wood grain.
Below in conjunction with embodiment the present invention is elaborated,
The specific embodiment
