Problems solved by technology

[0005] 2) Even if the mineral pellets can be painted with organic paint, the exposed mineral pellets have poor coloring stability after being exposed to the sun and rain for a long time. It is easy to fade, which not only affects the intensity of light reflection, but also pollutes the exterior wall or roof of the building;
[0006] 3) Adhesion of mineral granules: At present, the adhesion of mineral granules in shale coils in the market is poor, and mineral granules are easy to fall off during transportation and use. In the case of long-term exposure, the phenomenon of shale falling off is more obvious
[0007] At present, the lower surface of the modified asphalt waterproofing membrane cannot take into account the "oil leakage" and "heat resistance", and most of the water leakage is located at the overlapping edge of the membrane and the membrane
At present, after the construction of the modified asphalt waterproofing membrane, most of the water leakage occurs at the lap joint between the coil and the coil. Water, etc., while the modified asphalt with good fusibility and oily property has poor heat resistance, and slippage is likely to occur after construction, especially on the vertical wall
Especially for exposed coils, the industry problems of "high heat resistance, low oil output" and "high oil output, no heat resistance" limit the use of modified asphalt exposed coils

[0080] Mix and heat 30 parts by weight of 90# bitumen and 30 parts by weight of 200# bitumen to 150-160°C, add 2 parts by weight of SBR, shear and grind for 20-40 minutes, add 9 parts by weight of 25-35wt% star-shaped SBS and 3.5 parts by weight SIBS, heat up to 180-195°C, continue shearing and grinding for 40-70min, until the system becomes homogeneous, add 1.5 parts by weight of lake asphalt, 3 parts of anti-ultraviolet agent and 23 Parts by weight of filler, stirred for 30 to 50 minutes, to prepare a coating covering material with high adhesion modified asphalt layer on the upper surface;

[0081] Mix and heat 45 parts of 90# asphalt and 13 parts of softener to 150-160°C, stir for 20 minutes, add 12 parts of star-shaped SBS with a molecular weight of 280,000-350,000 and a styrene content of 30-40 wt%, and heat up to 185-160°C. 195°C, shear and grind for 60-80 minutes until the system is completely homogeneous, add 3 parts of viscosity reducer, 8 parts of C9 petroleum resin ...

Embodiment 2

[0085] The difference with Example 1 is:

[0086] Coating material for the high-adhesion modified asphalt layer on the upper surface: the star-shaped SBS with a molecular weight of 200,000 to 250,000 and a styrene content of 25 to 35 wt% increases by 1 part, SIBS decreases by 0.5 parts, and lake asphalt increases by 0.5 parts. Anti-ultraviolet agent reduced by 1 part;

[0087] Coating material for the lapping edge of the modified asphalt layer on the lower surface: 2 parts of star-shaped SBS with a molecular weight of 280,000 to 350,000 and a styrene content of 30 to 40 wt%, and 2 parts of C9 petroleum resin;

[0088] Coating materials for parts other than the lapped side of the modified asphalt layer on the lower surface: star-shaped SBS with a molecular weight of 200,000-250,000 and a styrene content of 30-35wt%, add 2 parts for star-shaped SBS, add 2 parts for linear SBS, APAO Reduced by 2 parts, fillers reduced by 2 parts;

Embodiment 3

[0090] The difference with Example 1 is:

[0091] Coating material for the high-adhesion modified asphalt layer on the upper surface: 5 parts of 90# asphalt, 1 part of SBR, 2 parts of star-shaped SBS with a molecular weight of 200,000 to 250,000 and a styrene content of 25 to 35 wt%. , SIBS increased by 0.5 parts, lake asphalt increased by 1.5 parts, anti-ultraviolet agent decreased by 1 part, filler decreased by 9 parts;

[0092] Coating material for the lapped side of the modified asphalt layer on the lower surface: add 2 parts of viscosity reducer, add 2 parts of star-shaped SBS with a molecular weight of 280,000 to 350,000 and a styrene content of 30 to 40 wt%, and reduce the amount of C9 petroleum resin 2 parts filler reduces 2 parts;

Abstract

The invention discloses an exposed type modified asphalt waterproof coiled material and a preparation method thereof. The exposed type modified asphalt waterproof coiled material is composed of an isolating layer, a lower surface modified asphalt layer, a reinforcing layer, an upper surface high-viscosity modified asphalt layer and a ceramic particle layer which are sequentially arranged, whereinthe lower surface modified asphalt layer comprises an overlap edge outer part and overlap edge parts on both sides of the overlap edge outer part. The exposed type modified asphalt waterproof coiled material can integrate the functions of waterproofness, energy conservation, attractive appearance, ageing resistance, vertical wall slipping resistance in summer and the like.

Description

technical field [0001] The invention belongs to the technical field of building waterproof materials, and more specifically relates to an exposed modified asphalt waterproof coiled material and a preparation method thereof. Background technique [0002] At present, the use of modified asphalt exposed membranes has a single function and will increase the urban heat island effect. In recent years, more and more attention has been paid to the energy saving and heat preservation of buildings. For waterproof materials, the single waterproof function can no longer meet the market demand. [0003] Hot-melt modified asphalt waterproofing membranes occupy the main market of waterproofing materials. Currently, only modified asphalt waterproofing membranes with mineral particles on the surface can be applied to external walls or building roofs. However, the modified asphalt waterproofing membranes exist The following disadvantages: [0004] 1) In terms of energy saving and consumptio...
