Description

A kind of metal Roof building waterproof heat-insulating coating and preparation method thereof
Technical field
The present invention relates to a kind of building coating, and in particular to a kind of building waterproof heat-insulating coating for metal Roof, with And the preparation method of coating.
Background technology
Metal Roof has the characteristics that high-strength light, flexible design, easy for installation, rich in color, moulding is unique, can make to build Build and produce stronger modern sense and times flavour, be widely used in industrial building and civil buildings.But with other construction materials Equally, metal Roof also has its weakness, and rain leakage is exactly one of them.Tracing it to its cause mainly has:1. material feature, 2. itself Design owe rationally, 3. construction wrong.
1. material feature itself.The connected mode that early stage metal roofing board uses is fastener connection, and roof boarding is tight Firmware penetrates fixation, and metallic plate destroys, and anticorrosive property is not strong, is also easy to produce Seepage.Thereafter speed III plate at the angle occurred II, angle of speeding Side connected mode is changed into the 180 ° of undercut connections of fixed support concealed type, although not having fastener to penetrate on roof boarding, this kind of plate Type is a kind of not close formula occlusion, and gap is big, and wind loading rating is weaker, once leak, than penetrating fixed form more very.To solve gold Belong to plate problem itself, domestic design is gone out the sealed connection template in full side of 360 ° of upright seam locking plates, set using special-purpose machines and tools machinery Standby undercut, tight type occlusion, there are certain free dilatability, and the metal roofing board template widelyd popularize at present.But metal The characteristic of expanding with heat and contract with cold of itself is so that the metal Roof of large span produces infiltration gap and can hardly be avoided.
2. design owes reasonable.Metal press plate roofing belongs to the category of constructional waterproofing, and drainability is strong, waterproof ability is weak, Once there is defect, leakage problems can not avoid system construction.Further, since hardware is connected with each other, detailed treatment is bad Heat bridge is easily formed, causes heat-insulation layer or interior condensation occur.Often there is leak and connection loosely in metal pressing plate roofing Gu phenomena such as, its main cause has:1)Construction treatment does not consider metal material swell-shrink characteristics, causes tie point tired, initiation is oozed Leakage;2)The slope of roof is too slow, template wave height is too small, and design is defective;3)Techonosphere is simple, containment system poor air-tightness, insulation There is condensation in layer;4)Template junction is weak, and it is poor that wind resistance takes off ability;5)Roof drainage design does not consider regional feature (Plum rains area, typhoon zone, accumulated snow area), cause waterproof defect.
3. construction reason: a)Movement joint sets and dealt with improperly.Movement joint, such as last-cost joint should be set according to design requirement, typically It could be constructed through 40-60d.Claim for eot, if because base cleaning or pour is smash bad hidden leakage defect can be left;For another example settle Seam, typically to arrive after steel-structure factory building binds to construct, and such duration is longer;As construction wrong can also leave hidden leakage defect. b)Uneven construction joint construction wrong causes to suffer from.According to existing construction convention, construct bottom plate when factory building roof construction height be 30- 50cm, then one of sealing piece is added, because construction of bottom plates uses merchant shapes more, the slump is larger, and exterior wall sheetmetal is as once The close lining that vibrates is often poor, and secondary vibration is difficult to some are brought in construction management, so the processing of this horizontal construction joint is not When the hidden danger for often turning into seepage.c)30cm convex walls complete most of drying shrinkage together with bottom plate in curing period at wallboard construction joint With shrinkage, new metal plate stitch combination after-contraction is received lower constraint, crack is also easy to produce more than 30cm joints.For gold Belong to the repairing of roofing infiltration leak, domestic early stage does not take much count of, and metal Roof waterproof is come pair as a simple question Treat, the existing waterproof material of generally use such as material common on the market:Polymer cement waterproof paint, polyurethane water-proof apply Material, silicone weathering glue, SBS waterproof rolls or self-adhesive waterproof roll material are handled, and it can solve steel structural roof in a short time Seepy question, but service life is not grown, the only some months of short life, long only 2-3, because this kind of waterproof layer There is no sealer, aging is poor, is easily invaded by external dust, corrosive substance, so that waterproof is dirty, becomes fragile, by Step is destroyed;Steel roofing summer temperature can reach more than 70 degree, and the pitch in coiled material is in molten condition, by multiple Fusing and solidification, coiled material aging depart from metal roofing board, and service life is also shorter.
With the raising of building energy conservation requirement, metal Roof heat-insulation and heat-preservation by warming plate based on present situation can not expire The needs developed enough, start to have the new technology for closing Metal roof heat-insulation waterproof paint, and waterproof and heat-insulating problem are planned as a whole into solution Certainly, the two large problems of metal Roof waterproof and energy-conservation are solved with a kind of material.For example, in Application No. 201310244734.X State's patent of invention discloses a kind of Water-resistant paint for steel structure color steel tile, the Chinese invention patent of Application No. 201510898394.1 Application discloses a kind of composite metal roof insulation water-repellent paint and preparation method thereof, and two kinds of technical schemes are all using hollow The materials such as glass microballoon prepare heat-insulating waterproof coating.But such coating that reflective insulation function is realized using microbead type, in life Production and application in there are problems that some can not avoid defect and:
