Waterproof roll is mainly used for construction wall, roofing and tunnel, highway, refuse landfill etc. and locates, play a kind of flexible building material product that is curled into web-like of resisting extraneous rainwater, ground water seepage, be connected as ne-leakage between engineering foundation and building, be the first barrier of whole engineering waterproofing, whole engineering is played to vital effect.Product mainly contains asphalt water-proof coiled material and polymer membranes.
Traditional asphalt waterproof roll is thermo-labile, easily trickling under high temperature, and the time has been grown, and waterproof coiled material impermeability declines.Aluminium-foil paper itself has superpower reflection and heat insulation, can reflect 60% above sun direct projection energy, but itself thermal conductivity is good, easily heating and heat being delivered on the watertight composition of its below, if but built on stilts below aluminium-foil paper, reserved certain circulation of air, effect of heat insulation can become fine., after aluminium-foil paper wrinkles, its surface tension can be amplified, the ability that then absorbs liquid strengthens greatly meanwhile, the oil suction that easily absorbs water, thus make coiled material become moist, shorten service life.
Utility model content
The purpose of this utility model is to overcome the weak point of above-mentioned conventional art, provides a kind of anti-flaming thermal-insulation, easy to maintenance, water resistance good, the polyurethane coating film waterproof roll of long service life.
The technical solution of the utility model is:
Polyurethane coating film waterproof roll, comprises asphaltic base watertight composition, it is characterized in that: described asphaltic base watertight composition upside is provided with enhancement layer, and described enhancement layer upside is provided with aluminium foil layer, and described aluminium foil layer upside is provided with dual-component polyurethane film layer.Dual-component polyurethane film layer is to be made up of double-composition polyurethane waterproof paint, double-composition polyurethane waterproof paint is a kind of two component reaction-curable macromolecule environment-friendly waterproof paint, first component is the base polyurethane prepolymer for use as being obtained through polycondensation reaction by polyethers and isocyanates, the colour liquid that second component is made up of plasticizer, curing agent, thickener etc.The first and second components are mixed, and after stirring, brushing solidify to form the rubber-like elasticity film of high resilience, toughness and wearability, has good corrosion-resistant and oil resistivity, effectively protects the aluminium foil layer of downside.
A kind of concrete prioritization scheme, described enhancement layer is fiberglass gridding cloth layer.Described fiberglass gridding cloth layer is to make by some glass fibers are cross-laminated, there is good heat resistance and stretch-proof ability, high temperature resistant, do not fire, anticorrosive, heat-insulating sound-insulating, but wearability is poor, coordinate dual anti-flaming thermal-insulation with aluminium foil layer, good adiabatic function, simultaneously as enhancement layer, the tensile strength that has effectively strengthened asphaltic base watertight composition and aluminium foil layer, extensibility is good.
A kind of concrete prioritization scheme, described asphaltic base watertight composition is that SBS rubber modified asphalt watertight composition, APP modified asphalt waterproof layer or PVC modification tar asphalt layer are wherein a kind of.
A kind of concrete prioritization scheme, described asphaltic base watertight composition downside is provided with self-adhesive layer, and described self-adhesive layer downside is provided with separation layer.
A kind of concrete prioritization scheme, upper and lower two surfaces of described aluminium foil layer are exasperate.Exasperate aluminium foil layer,, there is gap in its rough surface, thereby forms air heat-insulation layer each other, prevent aluminium foil layer self heat is delivered on asphaltic base watertight composition and its tensile strength of exasperate aluminium foil layer much larger than shiny surface aluminium foil layer.
The utility model has adopted with upper type, has the following advantages:
There is complete elastic waterproof layer, the water proof anti-seepage ability that has improved architectural engineering, polyurethane coating film has higher intensity and extensibility, to base course crack or flexible strong adaptability, maintenance easily, only need, to the locally sprayed repairing of damaged location, still can reach original waterproof effect, save time, laborsaving, expense is low, and there is environment protecting, and complementary structure between other layer, works in coordination, and has extended the service life of coiled material.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Detailed description of the invention
Embodiment 1: as shown in Figure 1, polyurethane coating film waterproof roll, comprise asphaltic base watertight composition 4, described asphaltic base watertight composition 4 upsides are provided with fiberglass gridding cloth layer, described fiberglass gridding cloth layer upside is provided with exasperate aluminium foil layer 2, and described exasperate aluminium foil layer 2 upsides are provided with dual-component polyurethane film layer 1.
Described asphaltic base watertight composition 4 is SBS rubber modified asphalt watertight composition.Certainly, can be also the watertight composition of APP modified asphalt waterproof layer or PVC modification tar asphalt layer or other asphalt materials.
Described asphaltic base watertight composition 4 downsides are provided with self-adhesive layer 5, and described self-adhesive layer 5 downsides are provided with separation layer 6.
When use, can throw off separation layer 6, by direct coiled material paving on dry ground, easy construction.
