The specific embodiment

Below in conjunction with accompanying drawing 1, the present invention is elaborated.

A kind of antiseepage fire prevention external thermal insulation system comprises basic unit (1) body of wall, leveling layer (2), grout blanket (3), insulation layer (4), cloth two glue-lines (5), carrier layer (6), finish coat (7) from inside to outside successively.Leveling layer (2) is cement sand bed, be bonded in basic unit (1) surface, the adhesive linkage that grout blanket (3) forms for liquid foamed heat insulating glue perfusion, liquid foamed heat insulating glue is comprised of adhesive mortar, blowing agent, 42.5 repaid hardening sulphoaluminate cements, quartz sand, and its weight ratio is (3-8): (1-3): (10-20): (30-60).Grout blanket (3) is bonding leveling layer (2) and insulation layer (4) respectively, insulation layer (4) is polyphenyl plate or extruded polystyrene board, one cloth two glue-lines (5) scribble the alkaline-resisting grid cloth of anticracking grout for two sides, difference bonding and thermal insulation layer (4) and carrier layer (6), carrier layer (6) is inorganic clad plate or high density polyphenyl plate, its surface coverage has finish coat (7), and finish coat (7) is that liquid marble paint or the spraying of fluorine carbon paint form.

Its construction method is:

The first step: first to basic unit (1) metope inspection, processing, remove the attachment that affects bond effect, reject surface of wall projection, the basal plane of hollowing and weathering is tamped to levelling by 1:3 cement mortar.

Second step: hang horizontal vertical line according to architectural modeling and practice of construction condition, according to horizontal vertical line, make horizontal vertical band (guaranteeing vertical, the planeness of outer wall surface) with aluminum alloy square tube.

The 3rd step: while pasting polyphenyl plate heat preserving layer (4), first according to belt, fix, then (approximately 10-30 mm wide) is in the milk (for avoiding slurries to flow out from the side to the gap between polyphenyl plate and leveling layer to use liquid foamed heat insulating glue, in advance that the both sides in gap are stifled tight, this insulation glue good fluidity also has the microdilatancy effect of blowing agent simultaneously).This kind of method made up defect and the deficiency of old-fashioned way, because old-fashioned mounting method is to take 9 glue as main, between polyphenyl plate and leveling layer there is 30% space in great majority, the cause of most fire be due to construction during electric welding field or other fall into the fire that the naked light in insulation layer space causes, and this kind of perfusion can make warming plate stickup closely knit, increased the area pasted (from original point sticky change into completely sticky), prevented cavity passage, stoped the circulation of air rainwater, antiseepage, fire prevention and heat-insulating property are obviously better than other construction method.

The polyphenyl plate of insulation layer (4) or extruded polystyrene board have the advantages such as quality is light, coefficient of thermal conductivity is little, hydrophobicity is strong, water resistance is good.Ultralow coefficient of thermal conductivity can prevent that temperature runs off by heat conducting form, the energy consumption of simultaneously considering building has 30-40% by building gap loss, prevent cavity passage, stop circulation of air, fireproof performance is obviously better than traditional fire prevention system, the infiltration of also having stopped rainwater simultaneously.

The 4th step: paste cloth two glue-lines (5) with anticracking grout.On insulation layer (4), smear anticracking grout bottoming, paste alkaline-resisting grid cloth, on alkaline-resisting grid cloth, smear again anticracking grout one time, then paste carrier layer (6), then direct bonding applique surface layer.

Alkaline-resisting grid cloth and two-sided anticracking grout can strengthen globality and the intensity of adhesive layer greatly; Carrier layer (2) is inorganic clad plate or high density polyphenyl plate, have that quality is light, intensity is high, the advantage such as moistureproof, waterproof, fire prevention, it cover net two glue-lines (5) above, increased the durability of mortar and grid cloth far away, make building obtain good protection; Finish coat (1) forms with high-grade liquid marble paint or the spraying of fluorine carbon paint, there is the durability of overlength, excellent self-cleaning function, can make multiple high-grade decorative effect, reach application life more than 25 years, during bonding applique surface layer, with special-purpose rolling tools pressing, compacting.

Every layer arranges 20 centimeters of wide fire barriers, has also increased fireproof performance.

The 5th step: to dividing joint (crack between every carrier layer) filling-foam bar, then fill silicone sealant to dividing joint, check and repair, check and accept.

The present invention decorates way with traditional high-grade external wall outer insulation and compares, and has greatly reduced construction cost, has improved construction quality, has beautified architectural appearance.
