Description
Technical field
The invention belongs to building waterproofing technique field, being specifically related to a kind of energy-conservation from protecting waterproof roof-working method.
Background technology
Buildings waterproof is anti-sealing to the infiltration at some position of building from constructional materials and textural taked measure.Waterproof be used in more roofing, underground building, building under ground portion and need the interior room and water storage structure etc. of waterproof.The measure taked by it and the difference of means, be divided into material waterproofing and the large class of constructional waterproofing two.Material waterproofing is the path blocking water by constructional materials, to reach the object of waterproof or to increase the ability of anti-leakage, as waterproof coiled material, coating waterproofing, concrete and cement mortar rigid waterproofing and clay, grey great soil group waterproof etc.Constructional waterproofing is then take suitable structural form, blocks the path of water, to reach the object of waterproof, as waterstop and cavity configuration etc.
The application of rigidity mortar waterproof technique can rational reduction of erection time, and reduce engineering input cost, environmental protect, is beneficial to environmental protection, saves social resources, meets conservation-minded society's view of development.The attention degree to impermeable structure possibility existing defects can be improved, be conducive to the perfect of primary prevention work.
The waterproofing course the selection of material of traditional roof building waterproof method should select the materials such as synthetic polymeric waterproofing material, polymer modified bituminous waterproof sheet material, sheet metal, synthetic macromolecular waterproof coating, pea gravel concreten.
Rigidity mortar waterproof agent generally can be divided into inorganic compound class, organic compound class, mixture class and complex class.Inorganic compound class has iron chloride, wollastonite powder end, zirconium compounds etc.Organic compound class is aliphatic acid and its esters, organic silicon surfactant (methyl silicon sodium alcoholate, ethyl sodium silanolate, poly-ethyl hydroxy siloxanes), paraffin, bitumen, rubber and water-soluble resin emulsion etc.Mixture class is mineral-type mixture, organic mixture, mineral-type and organic mixture.Complex class is the above-mentioned all kinds of composite water repellent with composition of concrete admixtures such as air entraining agent, water reducing agent, adjustable solidification agents.
What rigidity water-proofing material developed is initially iron oxides mortar waterproof agent, though this type of iron oxides mortar waterproof agent energy waterproof after construction, is eliminated early by market because effect is unstable.Inorganic aluminate class mortar waterproof agent, though permeability good in acid metal is corrosive and can reduces mortar strength easily cause be full of cracks, waterproofing course easily lost efficacy, and the life-span is also permanent, so that has exited anti-market for water gradually.Machine silicon class mortar waterproof agent is commonly used to exterior wall hydrophobic, if but the place of sand for unsaturated water of appearance such as washrooms that mix cement, effect is just very poor.
Summary of the invention
The object of the present invention is to provide a kind of energy-conservation from protecting waterproof roof-working method.
A kind of energy-conservation from protecting waterproof roof-working method, comprise the following steps:
1) on roof construction layer, lay the hydrophobic be made up of waterproof agent, cement, thermal insulation light aggregate looks for slope to hold concurrently insulation layer;
2) leveling layer be made up of waterproof agent, cement mortar is laid looking for slope to hold concurrently on insulation layer;
3) on leveling layer, lay the flexible waterproof layer that one deck is made up of flexible adhesive waterproof coil;
4) on flexible adhesive waterproof coil, lay the topping be made up of waterproof agent, cement mortar;
5) layer of metal roof acrylic acid high-elastic waterproof coating or floating by waterproof agent, cement mortar is laid on the protection layer.
Described waterproof agent is for be made up of according to following quality proportioning following raw materials according: neat soap 20-40%, NaOH 4-8%, silicate of soda 0.1-0.25%, potassium bichromate 3-8%, tributyl phosphate 1.5-2 ‰, neopelex 0.1-1.0%, cellulose 1-5 ‰, excess water.
Thermal insulation light aggregate described in step 1) is lytag, coal gangue haydite, glass bead or expanded perlite; The particle diameter 0.1-2mm of described thermal insulation light aggregate, bulk density is less than 120Kg/ every cubic metre, and water absorption rate is less than 50%, and coefficient of thermal conductivity is less than 0.050w/mk.
In step 1), the mass ratio of thermal insulation light aggregate, cement and waterproof agent is 1.5:1:0.01-3.
The hold concurrently thickness of insulation layer of slope is looked for be 20mm-50mm described in step 1).
Step 2) thickness of described leveling layer is 18-20mm.
The individual layer self-adhered polymer modified asphalt membrane of to be thickness the be 1.5mm-2mm of flexible adhesive waterproof coil described in step 3), without carcass.
Topping described in step 4) is 18-20mm.
In described waterproof agent, cement mortar, the quality proportioning of cement, sand, waterproof agent is: 1:2.5:0.01-3.
The acrylic acid of metal Roof described in step 5) high-elastic waterproof coating, luminous reflectance is more than or equal to 0.80, and hemispherical emissivity is more than or equal to 0.80; Thickness of coating layer is 0.8mm; The described thickness floating by waterproof agent, cement mortar is 10mm.
Beneficial effect of the present invention is:
1, environment-friendly advantage: adopt cold construction method to construct, pollution is not produced to environment.
2, rigid flexible system, Integral sealing waterproof: the present invention utilizes rigid material, flexible material forms one airtight waterproofing course, reaches the Integral sealing waterproof effect that hard and soft gapless combines.
3, adhere to, adhesive property: can with concrete, cement sand plaster tight adhesion; this adhesion property did not lose efficacy because of immersion; thus the waterproofing system that the hard and soft gapless forming the diffusion of breakage leakproof combines; there will not be channeling water phenomenon; lasting protection, protected effect are formed to cement concrete simultaneously, improve the durability of concrete structure.
4, construction safety, quick: do not adopt naked light in work progress, stopped disaster hidden-trouble, greatly can improve speed of application, shorten the construction period.
5, alleviate roofing weight, reduce roofing temperature: this construction method contains waterproof, insulation, levelling, sloping layer, effectively alleviates roofing weight, effectively reduces the temperature of roofing.
6, the application of the heat insulation sloping layer of hydrophobic heat-insulating, not only improves intensity, realizes hydrophobic object, can reduce coefficient of thermal conductivity again, improves thermal property.
7, perennity uses, the life-span same with building.
8, good with various roofing matching, comprise concrete, metal, wooden, watt or the roofing such as synthetic tile.Directly can use on existing impaired waterproofing materials surface, can not only water-proof function be recovered, can reach from protection effect again, prolongation building application life.Also various material property can be utilized separately, for other roofing materialss do supporting.
9, low to basic level requirement, can construct at moisture substrate, compliance is stronger, and the scope of application is wider.
10, body series not only environmental protection, energy-conservation, also can save the maintenance cost of building and extend the application life of building.
11, body series all material can be used alone or compound use by different construction part, different using function.
12, UV resistant, can be used for exposing self waterproofing topping.
The present invention's waterproof agent used meets national building materials industrial construction cladding and duct products quality monitoring detects test center's foundation:
