Abstract
The utility model relates to a roof insulating layer structure, in particular to a roof polyurethane composite heat insulating and waterproof system; a polyurethane spraying layer is sprayed on a roof; a water aqua type composite waterproof layer is smeared on the polyurethane spraying layer; and a roof normal hard cover layer is added on the water aqua type composite waterproof layer. For preventing the water aqua type composite waterproof layer from being damaged in the process of exerting the normal hard cover layer, the polyurethane spraying layer is added on the water aqua type composite waterproof layer for protecting the water aqua type composite waterproof layer and enabling the water aqua type composite waterproof layer to be more insulated. The roof insulating and waterproof integrity is good, and the roof is firmly bonded with the base layer, so that the heat insulating and the watertightness are integrated. The system is constructed on site by overall spraying, does not have joints, better solves the local frosting and mustiness phenomena, and can effectively prevent cracking; and the system is stable in chemical properties, long in service life, good in fireproofing safety and simple and scientific in construction, and achieves the energy-saving requirements.
Description
Technical field
The utility model relates to a kind of roofing heat-insulating layer structure, i.e. roofing polyurethane composite thermal insulation waterproofing system.
Background technology
In the prior art, the roof heat insulation waterproof is the problem of a headache for the people who lives attic, and roof heat insulation and waterproof are two individual system at present, insulation non-watertight, not being incubated of waterproof.What now generally be used for roof heat insulation is polyphenyl plate, extruded sheet, what waterproof was used is macromolecular material and SBS coiled material, more than two kinds of heat insulating material coefficient of thermal conductivity big, be assemblied with seam, easily produce " thermal center " and " cold bridge ", not in place because of sheet material insulation assembly unit, cause local slow white Signs of Mould, do not reach energy-conservation requirement.Combine badly between waterproofing course and the insulation layer, cause waterproof also not reach requirement, waterproofing course is once occur leaking, and insulation layer also loses heat insulation effect thereupon.
The utility model content
The purpose of this utility model is to provide a kind of employing polyurethane material as insulation water-proof layer at above-mentioned deficiency, has the better roofing polyurethane composite thermal insulation of result of use waterproofing system.
Technical solution of the present utility model is: roofing polyurethane composite thermal insulation waterproofing system is the polyurethane coating layer that sprays on roofing, on the polyurethane coating layer, smear the water aqua type complex waterproof layer, on the water aqua type complex waterproof layer, add the normal hard covering layer of roofing.For preventing when applying normal hard covering layer, to destroy the water aqua type complex waterproof layer, on the water aqua type complex waterproof layer, have additional the polyurethane coating layer, play the effect of protection water aqua type complex waterproof layer, simultaneously insulation more.The polyurethane coating layer mainly plays the effect of thermal-insulating waterproof; it on the polyurethane coating layer water aqua type complex waterproof layer; form complex waterproof layer with polyurethane; make roofing reach waterproof completely; increase the polyurethane coating layer on the water aqua type complex waterproof layer again; mainly play the effect of polyurethane protection water aqua type complex waterproof layer, prevent that the water aqua type complex waterproof layer is damaged when construction.Hard covering layer plays the effect of permanent protection.Polyurethane directly is sprayed on the roof-base, when being sprayed onto apart from design thickness difference 0.5mm～1mm, smears the thick water aqua type complex waterproof layer of 1mm～1.5mm, again with polyurethane coating to design thickness.The water aqua type complex waterproof layer is clipped in the middle to protect, and we have promptly reached insulation and have accomplished that again waterproof is perfectly safe like this.After finishing, does system construction the hard covering layer of normal roofing (cement mortar or steel concrete or sticking brick etc.) in the above.The water aqua type complex waterproof layer is to adopt coating waterproofing coating commonly used, and coating waterproofing coating mainly contains polyurethanes water-repellent paint, acrylic type water-proof coating, rubber asphalt class water-repellent paint, neoprene class water-repellent paint, silicone based water-repellent paint and other water-repellent paint etc.Unit weight 45kg/m
3Polyurethane promptly be incubated and waterproof, good stability, coefficient of thermal conductivity are 0.024W/mk, its coefficient of thermal conductivity only is half of EPS polystyrene block; Its superpower self-adhesion performance need not any middle binding material, bonds firmly with basic unit.
The utility model has the advantages that: 1, the roof heat insulation water tight integrity is good, bonds firmly with basic unit, makes thermal-insulating waterproof integrated.2, on-the-spot integral spray construction, no seam has well solved local slow white Signs of Mould, has eliminated " thermal center " and " cold bridge " fully, and can effectively prevent cracking, its stable chemical performance, long service life, the fire safety performance is good, and easy construction is scientific, reaches energy-conservation 65% requirement.3, simple in structure, reduce cost, make the thermal-insulating waterproof integral system be widely used in flat roof deck, oblique roofing, various special-shaped roofing.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Description of drawings
Accompanying drawing is the utility model structure diagram.
The specific embodiment
Referring to accompanying drawing, roofing polyurethane composite thermal insulation waterproofing system is a spraying polyurethane sprayed coating 2 on roofing concrete basal plane 1, on polyurethane coating layer 2, smear water aqua type complex waterproof layer 3, on water aqua type complex waterproof layer 3, add polyurethane sprayed coating 4 again, on polyurethane coating layer 4, add the normal hard covering layer 5 of roofing.During construction, cleaning roofing floating dust, oil stain, local uneven place cement mortar screeding, with import high pressure painting equipment with polyurethane coating to apart from design thickness difference 0.5mm～1mm the time, smear 1mm～1.5mm water aqua type complex waterproof layer 3 (water aqua type waterproof coating layer) again, continue spraying polyurethane after water aqua type complex waterproof layer 3 is finished again, polyurethane coating to design thickness, is done the normal hard covering layer 5 of roofing again after polyurethane coating is finished.
Claims (2)
1. roofing polyurethane composite thermal insulation waterproofing system, it is characterized in that on roofing (1), being coated with polyurethane coating layer (2), on polyurethane coating layer (2), smear water aqua type complex waterproof layer (3), on water aqua type complex waterproof layer (3), add the normal hard covering layer (5) of roofing.
2. roofing polyurethane composite thermal insulation waterproofing system as claimed in claim 1 is characterized in that having additional polyurethane coating layer (4) on water aqua type complex waterproof layer (3).
