Abstract
The utility model discloses a waterproof structure for a roof surface, and belongs to the technical field of waterproofing of buildings. The structure comprises a heat-insulation layer lain on the roof surface, a screed-coat lain on the heat-insulation layer, and a waterproof layer lain on the screed-coat. The waterproof layer is a composite waterproof layer which consists of a rigid waterproof layer, a silane dipping water-proof layer, and an elastic waterproof paint layer from the bottom to the top. Three waterproof layers are employed for water prevention, and a seamless continuous waterproof layer is formed on the roof surface. The structure is excellent in waterproofness and good in air permeability, effectively prolongs the waterproof service life of the roof surface, and is especially suitable for roofs of high-rise buildings, important buildings, and buildings which have special requirements for water prevention.
Description
Technical field
The utility model patent relates to a kind of roof covering water-proof structure, belongs to building waterproofing technique field.Be particularly useful for highrise building, important building and waterproof had to the building roof waterproof of specific (special) requirements.
Background technology
Building roofing waterproofing course is divided into rigid waterproof layer, waterproof roll and water-repellent paint.Rigid waterproofing layer thickness is large, intensity is high, can tolerate puncture and destroying, can withstand long term exposure water in the erosion of the erosion such as acid, alkali, chlorine class, but be subject to temperature difference strain, produce a large amount of micro-cracks, cause local infiltration, waterproofing course inefficacy.
Existing waterproof roll is divided into pitch class waterproof roll, polymer modified bituminous waterproof sheet material, high polymer waterproof roll.The trickling of asphalt water-proof coiled material high temperature, low-temperature embrittleness, easily aging, the life-span is short; Polymer modified bituminous waterproof sheet material has good high and low temperature resistance, extensibility, toughness, ageing-resistant performance etc., but still be by oil as raw material, there is toxicity, not environmental protection; High polymer waterproof roll is as Ethylene Propylene Terpolymer, polyvinyl chloride, haloflex, blend rubber and ternary butyric rubber waterproofing coiled material, better performances, but production technology is too complicated.Waterproof roll needs binding material and overlap joint in work progress, often there will be the situations such as layering, a drum, channeling water, seam crossing leak.
Existing water-repellent paint is polyurethanes water-repellent paint, mulseal class water-repellent paint, aqueous acrylamide ester emulsion class water-repellent paint, silicone rubber kinds water-repellent paint, polyurea waterproof coating material and cement polymer.Polyurethanes water-repellent paint wet poor adhesion, contain free isocyanate; Mulseal class water-repellent paint high temperature after-tacks, easily shrinks and is poisonous; Aqueous acrylamide ester emulsion class water-repellent paint drying time is long, easily shrink, solvent-resisting is poor; Silicone rubber kinds water-repellent paint difference of hardness, viscosity is high and easily stain; Polyureas water-repellent paint poor adhesive force, need primary coat, weatherability poor, need professional construction equipment; Cement polymer class water-repellent paint crack bridging ability, hardening time is long completely.
Summary of the invention
For addressing the above problem, the utility model provides a kind of roof covering water-proof structure, carries out three road waterproof guards, at roofing, forms jointless continuous waterproofing course.
The utility model is realized with following technical scheme: a kind of roof covering water-proof structure, comprise the insulation layer that is laid on roofing, be laid on the leveling layer on insulation layer and be laid on the waterproofing course on leveling layer, described waterproofing course is complex waterproof layer, and described complex waterproof layer is by being comprised of rigid waterproof layer, impregnating with silane waterproofing course and elastic water proofing paint layer from bottom to top.
Described rigid waterproof layer is common pea gravel concreten layer or expansive concrete layer.
Described elastic waterproof layer is Silante terminated polyethers water-repellent paint coating.
Further preferably, described Silante terminated polyethers water-repellent paint coating is alpha, alpha-dimethyl TMOS end capped polyether resinous coat or γ-trimethoxy silane end capped polyether resinous coat.
Described impregnating with silane waterproofing course is isobutyl group trimethoxy silane paint coatings or isobutyl triethoxy silane paint coatings or iso-octyl alkene trimethoxy silane paint coatings or iso-octyl alkene triethoxysilane paint coatings.
Owing to having adopted technique scheme,
(1) adopt complex waterproof layer, complex waterproof layer is comprised of rigid waterproof layer, impregnating with silane waterproof agent, elastic water proofing paint, set up defences in three roads, form jointless continuous waterproofing course, there is excellent water proofing property and good gas permeability, first cost drops into high, and the waterproof life-span is long, reduces later maintenance.
(2) on leveling layer, cover a rigid waterproof layer, rigid waterproof layer has good durability and anti-wear performance, and insulation layer is formed to effective protection.
(3) introduce Novel permeation type impregnating with silane waterproof agent, this waterproof agent can penetrate in mortar, the hydrophobic structure of formation-Si-O-Si-, thereby play waterproof effect, not only on surface, play waterproof action, for the crack below 0.2mm, also there is good waterproof effect, can effectively make up the infiltration that rigid waterproof layer cracking causes, and there is good gas permeability.
(4) introduce elastic water proofing paint, this water-repellent paint is Silante terminated polyethers water-repellent paint, after rapid curing, form one firmly elastic water-proof film; Through 0.3MPa, the waterproof test of 30min is not seeped water; High temperature does not after-tack, water resistance excellent and have gas permeability.This water-repellent paint has good adhesive power at concrete, mortar, glass, pottery and timber and a lot of metal surface, and UV resistant, heat-proof aging and excellent chemical resistance are not containing solvent, containing free isocyanates, not environment friendly and pollution-free.
The beneficial effects of the utility model are: in roof covering water-proof structure, adopt complex waterproof layer, carry out three road waterproof guards, at roofing, form jointless continuous waterproofing course, there is excellent water proofing property and good gas permeability, effectively increased the roof waterproof life-span, be particularly useful for highrise building, important building and waterproof had to the building roof waterproof of specific (special) requirements.
