Abstract
The invention discloses a method for repairing metal fluorocarbon paint outer wall coating defects. The method includes the nine steps of surface processing, cutting seam manufacturing, batch puttying of a rough putty layer, batch puttying of a fine putty layer, polishing of putty layers, rolling coating of oil primer for fluorocarbon, rolling coating of true-color fluorocarbon finishing coat, rolling coating of coating varnish for the outer wall fluorocarbon and coloring seam by seam. A repair tool used for repairing the metal fluorocarbon paint outer wall coating defects is composed of a rolling drum and a silk stocking, after the rolling drum is soaked, the silk stocking is sleeved on the rolling drum, and then the repair tool is formed. The repair method is not limited by electric power and machinery, saves construction cost, is simple in procedures, convenient to operate and good in effect, protects the environment, and is capable of being used for a steel structure, a mortar wall and a concrete surface layer.
Description
Technical field
The present invention relates to construction exterior paint technical field, be specifically related to a kind of method for repairing and mending of metal fluorocarbon coating exterior wall painting defect.
Background technology
Metal fluorocarbon coating is a kind of exterior wall coating material of high-quality, and it can resist the adverse effect of ultraviolet, harsh weather, complex environment etc., can resist the osmosis of corrosive ions, and has overlength weatherability and corrosion resistance and excellent self-cleaning function.In engineer applied, designer usually utilizes metal fluorocarbon coating to reach the effect of Aluminium and plastic board curtain wall, adopts it to save construction costs.Thus, in practice of construction process, metal fluorocarbon coating is low with its cost, easy construction, the durable advantage such as self-cleaning attractive in appearance, there is obvious Social benefit and economic benefit.But in engineering practice, easily there is the mass defects such as hollowing, delamination, crack due to metal fluorocarbon coating surface, thus have a strong impact on elevation of building perception, directly impact is caused on workmanship, also have influence on the attractive in appearance of building.Particularly go out local mass defect, when needing to repair, also exist that construction organization inconvenience, scaffold installation difficulty are large, high pressure painting equipment connects that electricity is inconvenient, thinner to pollution of surrounding enviroment etc., inconvenience.
Summary of the invention
The object of the invention is for the problems referred to above, a kind of method for repairing and mending of metal fluorocarbon coating exterior wall painting defect is provided, the defect such as hollowing, delamination, crack that metal fluorocarbon coating coating surface easily occurs is repaired, keep the attractive in appearance of external wall.
For achieving the above object, the technical solution adopted in the present invention is:
A method for repairing and mending for metal fluorocarbon coating exterior wall painting defect, comprises the steps:
(1) surfacing
With the original basic unit of grinder buffing, point mends depressed area, the outstanding position of polishing; Sand paper completely grinds basal plane, bar negative and positive angle, correction windows sideline etc.;
(2) work is made in cutting
Cut cut-off rule or push up embedding glazing bar, filling up Pasteur's glue, extruding Pasteur glue, revises and paints;
(3) criticize and scrape thick putty layer
Batch scrape the thick putty of water-proof elastic, repair basal plane defects, smooth with 300# sand papering, dry too fast time atomized water spray maintenance, do twice altogether, before entering operation, 24 hours, interval, winter, appropriateness extended, and according to user's requirement, all or at least at the position of window frame, beam, post separately drew in the net to process;
When using common thick putty, label lower than 10mpa, and should not mix " gram row are built " special cracking resistant fiber that volume ratio is 0.1% in mortar;
(4) criticize and scrape fine and smooth sublayer
Batch to scrape the fine and smooth son of water-proof elastic, finishing basal plane defects, smooth with 300# sand papering, dry too fast time need wet curing, do twice altogether, before entering next procedure, 7 days, interval, winter, appropriateness extended;
Use the fine and smooth period of the day from 11 p.m. to 1 a.m, " gram row are built " special cracking resistant fiber that volume ratio is 0.1% should be mixed in floating mortar;
(5) polished putty layer
Criticize and scrape fluorine carbon type polished putty, smooth with 800# sand papering, do twice, before entering next procedure, 24 hours, interval, winter, appropriateness extended;
(6) the special oil primer of roller coating fluorine carbon
Use the special repair outfit that cylinder and silk stocking make, the special oil primer of roller coating fluorine carbon, infiltrate basic unit, formed without interface coating, priming paint forms cross-linked structure on basal plane, polishes smooth when grinding with 600# sand paper, before entering next procedure, 24 hours, interval, winter, appropriateness extended;
(7) the real look fluorine carbon finishing paint of roller coating
The real look fluorine carbon finishing paint of roller coating, provides tough and tensile diaphragm and fluorine carbon effect surface, does twice altogether, polish gently with sand paper after constructing for one time dry 3-4 hour, removing surface dirt, technique for grinding should adopt wet grinding, firmly will gently want evenly, sand paper requires 600 orders or 800 orders; During second time roller coating, ensureing, not under sagging prerequisite, coating to be rolled thick, to ensure surperficial levelling effect as far as possible;
(8) the special coating varnish of roller coating exterior wall
Keep even speed roller coating twice coating varnish, the bright and clean lucid and lively feel of coating surface is provided and has more resistant, weather-proof, discoloration-resistant performance;
(9) dividing joint colouring
Tear the face glue that dividing joint pastes off, be in line with one side sticker again on dividing joint both sides;
With Pasteur's glue by dividing joint colouring (twice), midfeather more than 1 hour, note keeping groove mark level and smooth, strain line is straight.
Wherein, described special repair outfit is made up of cylinder and silk stocking, after being soaked by cylinder, silk stocking is enclosed within cylinder, depending on the smooth fineness of metope, can increase the number of plies of silk stocking or select silk stocking hole size.
After partition seam has been painted, also need to check construction quality.
