Description
Technical field
The utility model relates to a kind of architectural waterproof material, and the concrete of CPS modified asphalt layer that particularly a kind of and concrete reacts and macromolecule layer, fibrage combination overlays, wet waterproof sheet or the coiled material spread.
Background technology
At present, be used for the tunnel in the communications and transportation, subway basement and be used for shed deckhead, civil air defense constructions and installations, the dykes and dams culverts and water gates, the construction works of the water proof anti-seepage in all kinds of ponds is more and more, in order to waterproof materials mainly is coating and various sheet material or coiled material, appearance along with the macromolecular sheet material of asphalt water-proof coiled material or narrow fabrics layer, because it can batch production production, easy to use, in building operations, use the favor that more and more is subjected to people, tunnel particularly, the construction of subway basement and dykes and dams culverts and water gates end face, the one side that modified bituminous pitch coiled material is had adhesive directly pastes the purpose that concrete surface just reaches waterproof.Open source literature also discloses the technology of some this respects, Chinese patent for example: flexible polymer modified cement base waterproof material and preparation method thereof, application number: 00819308, notification number: CN1450955, applicant: Building Material Science Inst., Tianjin, summary: this invention relates to a kind of waterproofing materials that contains cement and polymer that is used for building structure and preparation method thereof, and said cement is hydraulic cement, and said polymer comprises modified acrylic acid emulsion and toughness reinforcing rubber.This preparation method may further comprise the steps: (a) with the weight ratio of cement/emulsion solid content 100: 15-150, mediate cement and emulsion moisture in kneaded material is reduced to 5-20% (weight) in the temperature of 20-80rpm and 25-125 ℃, (b) mixing, plasticate also, calendering formation kneading material is 100 with toughness reinforcing rubber weight ratio: the mixture of 10-50 obtains waterproof sheet or coiled material.
The patent of Qinhuangdao, Hebei province Zhang Shoubin application and for example: layer high molecule waterproof roll, application number: 00245890, the applying date: 2000.08.15, notification number: CN2442835, summary: a kind of layer high molecule waterproof roll, its cross section is at least four layers of structure, from top to bottom is followed successively by: 1. 2. 3. 4. filament polypropylene fibre non-woven fabric soffit topping of polypropylene waterproof film lamella of EVA resin modified polyethylene waterproof enhancement layer of filament polypropylene fibre non-woven fabric upper surface topping; The filament polypropylene fibre non-woven fabric material external surface on its upper and lower surface has the groove and the projection of stereo grid shaped rectangle and/or rhombus.
The inventor has passed through in the abundant investigation back in market and has found, above patent and being seen on the market now waterproof roll are mainly modified asphalt waterproof coiled material, macromolecular sheet material, the many oil with hot melt application or at the bottom of being coated with oiliness pool cream, oiliness of its job practices, macromolecule glue are bonding, exist highly energy-consuming, danger, big, the moist basal plane of environment pollution to construct bonding insecure; With liquor-saturated latex cement adhesive of polyethylene and the bonding waterproof roll of other polymer latex cement, they are to form physical absorption by cement slurry between the moistening and basal plane and certain mortise and tenon effect is bonded on the basal plane, the as easy as rolling off a log factor affecting such as the damp and hot circulation of environment, steam expansion, basic unit's motion that are subjected to, the process that produces desorption and take off mortise and tenon, thereby adhesion stress is descended, lose the waterproof effect of permanent closure.
Summary of the invention
The purpose of this utility model is in order to overcome disadvantages of background technology, the problem of avoiding the common shop waterproof roll that overlays, wets to exist, the inventor uses bonding technology, by the double action of chemical reaction type and physics mortise and tenon, reach and tight to combining, firm, irreversible as closely linked as flesh and blood the bond effect of waterproof matrix.
The technical solution of the utility model is achieved in that
Three-in-one waterproof roll; comprise fibrage, macromolecular sheet material layer and pitch binder layer; be characterized in: described pitch binder layer is the modified asphalt layer that can play chemical crosslink reaction and the collaborative cementation of physics mortise and tenon with concrete jointly; its interlayer structure is as follows: fibrage, macromolecular sheet material layer, modified asphalt layer, thinfilm protective coating, each interlayer is by hot melting cohesion in the manufacturing process.
Above-described fibrage is natural fiber, synthetic fibers or the blend fibre that mesh is arranged or do not have mesh.
Above-described macromolecular sheet material layer is polyvinyl chloride, polyethylene, haloflex polypropylene or mixes the macromolecular sheet material layer.
Above-described thinfilm protective coating is polyethylene sheeting or polyvinyl chloride film.
The utility model compared with prior art has following outstanding feature:
1. bonding force is big.The utility model be a kind of can with concrete rise jointly chemical crosslink reaction and the synergistic modified bitumen of physics mortise and tenon and macromolecule, fibrage, polymer material layer and adhesive layer be combined with each other can overlay with the concrete of working face bonding, wet shop multi-layer water-proof coiled composite material, wriggling penetrates into cement gel and concrete pore in cement, concrete setting process, forms to have that bonding force is bigger, bonding is irreversible, bonding is tempered toughness with gentleness; Bonding more lasting concrete overlays, wet shop multilayer flashing coiled material, reach in conjunction with tight, firm, irreversible as closely linked as flesh and blood bond effect, its bonding force is big, physical absorption and mortise and tenon effect are not only arranged, and the mortise and tenon position generation chemical bonding effect of going down to the grass-roots units, make collaborative the carrying out of two kinds of effects of mortise and tenon and chemical crosslinking, make bonding more firm.Even the coiled material top layer is destroyed, the interface of bonding basal plane can be not impaired and produce and scurry the water drainage yet.
2. it is irreversible to bond.Because there is chemical b ` in region of interest, this bonding is irreversible, wants to take away or peel off waterproofing course, is difficult to accomplish, unless destroy coiled material, shovels the interface of roll out material and basic unit's bonding.
3. bonding is tempered toughness with gentleness.Form flexible adhesion by physical absorption and mortise and tenon effect,, and bond, make boundary layer that enough adhesion strengths be arranged, be highly resistant to the destruction of extraneous stress by the rigidity that chemical bond produces with the stress of elimination owing to basic unit's variation generation.
4. bonding lasting.Physical absorption and mortise and tenon often under the effect that solvent, steam or basal plane expand with heat and contract with cold, produce desorption and take off the process of mortise and tenon, thereby adhesion stress is descended, and lose the waterproof effect of permanent closure.Owing to have the chemical bonding effect at the mortise and tenon position, be not subjected to damp and hot circulation, steam expansion, basic unit's motion effects, and produce adhesiving effect enduringly, make the waterproof life-span of coiled material identical with body layer.
5. wide adaptability.The utility model is a kind ofly not only can use under the environment of drying, and can also relatively use under the harsh conditions, when working face is relatively moister, then adopt sticking sheet material of bar or coiled material construction, like this, the moisture content on the working face will be discharged by the place that does not have bonding between fibrage and the macromolecular sheet material layer.
