Description

Technical Field

[0001] This invention relates to the field of waterproof membrane technology, specifically to an exposed double-layer interlocking waterproof membrane. Background Technology

[0002] Precast waterproof membranes are increasingly widely used in waterproofing construction for building and municipal engineering projects. Precast waterproof membranes are waterproof membranes laid before structural construction; they are primarily composed of polymers with a self-adhesive layer on the surface. After installation, precast waterproof membranes allow for direct laying of reinforcing steel and concrete, offering low cost, fast construction speed, and excellent puncture and tear resistance. They are a highly efficient, convenient building material with superior physical and chemical properties.

[0003] However, due to its self-adhesive adhesive, its heat resistance and aging resistance are poor, making it unsuitable for outdoor use. Therefore, its current application is mainly in underground engineering, where it is pre-laid to achieve full adhesion to the structure. Its good interlocking and overlapping increases the water seepage path. In addition, factory prefabrication also avoids water seepage between waterproof layers. Therefore, if these advantages of prefabricated rolls can be utilized, and good heat and aging resistance can be given to prefabricated rolls so that they can be used in the open, this is a problem to be solved. Summary of the Invention

[0004] This invention proposes an exposed double-layer interlocking waterproof membrane, which solves the problem of insufficient heat aging resistance of exposed double-layer interlocking waterproof membranes in related technologies.

[0005] The technical solution of the present invention is as follows: This invention proposes an exposed double-layer interlocking waterproof membrane, which, from top to bottom, comprises a multicolored mineral granule layer, a high-temperature resistant modified bitumen layer, a first polymer film base layer, a first high-temperature resistant modified bitumen self-adhesive layer, a second polymer film base layer, a second high-temperature resistant modified bitumen self-adhesive layer, and an isolation layer. The multicolored mineral granule layer shrinks inward by 6-10cm to form an upper overlap edge. A first isolation film is provided on the overlap edge. A 6-10cm overlap joint is provided between the first high-temperature resistant modified asphalt self-adhesive layer and the second polymer film base layer. The overlap joint is located on the opposite side of the overlap edge. A second isolation film covering the surface of the first high-temperature resistant modified asphalt self-adhesive layer is provided inside the overlap joint. The high-temperature resistant modified asphalt layer comprises the following components in parts by weight: 35-40 parts heavy cross-linked petroleum asphalt, 4-10 parts SMA, 7-9 parts softener, 2-3 parts SBS, 2-5 parts polyolefin, 8-10 parts rubber powder, 0.5-1 part antioxidant, and 25-30 parts modified filler A. The first and second high-temperature resistant modified asphalt self-adhesive layers each independently comprise the following components by weight: 33-38 parts heavy cross-linked petroleum asphalt, 8-12 parts SMA, 8-10 parts softener, 3-4 parts SBS, 2.5-3.5 parts granular styrene-butadiene rubber, 8-10 parts rubber powder, 1.5-2 parts oxidized polyethylene wax, 3 parts tackifier, and 20-27 parts modified filler B; The modified filler A includes wollastonite fiber, talc powder, and carbon black; The modified filler B includes wollastonite fiber, heavy calcium carbonate powder, and carbon black.

[0006] As a further technical solution, the preparation method of the modified filler A includes the following steps: Carbon black is added to a coupling agent solution, stirred, filtered, and dried to obtain a pre-dispersed powder. This powder is then added to talc powder and dispersed evenly. Wollastonite fiber is added and dispersed again to obtain a composite filler. Finally, a dispersant is added to obtain modified filler A.

[0007] As a further technical solution, the preparation method of the modified filler B includes the following steps: Carbon black is added to the coupling agent solution, stirred, filtered, and dried to obtain a pre-dispersed powder. Heavy calcium carbonate powder is added and dispersed evenly, then wollastonite fiber is added and dispersed again to obtain a composite filler. Finally, a dispersant is added to obtain modified filler B.

[0008] As a further technical solution, the mass ratio of wollastonite fiber, talc powder and carbon black is 1~2:1:0.02~0.1.

[0009] As a further technical solution, the mass ratio of wollastonite fiber, heavy calcium carbonate powder and carbon black is 1~2:1:0.02~0.1.

[0010] In the high-temperature modified asphalt layer of this invention, the mass ratio of wollastonite fiber, talc powder, and carbon black is controlled at 1~2:1:0.02~0.1. In the modified filler of the first and second high-temperature modified asphalt self-adhesive layers, the mass ratio of wollastonite fiber, heavy calcium carbonate powder, and carbon black is controlled at 1~2:1:0.02~0.1. This mass ratio improves the heat aging resistance better. However, if there is too much wollastonite fiber, it will affect its flexibility and reduce the overall performance; if there is too little wollastonite fiber, it will not be enough to improve the heat aging resistance. If there is too much carbon black, it will affect the viscosity of the asphalt; if there is too little, its resistance to photothermal aging will be insufficient.

[0011] As a further technical solution, in the preparation process of modified filler A and modified filler B, the mass ratio of carbon black and coupling agent solution is independently 1:0.2~0.3; The mass ratio of the coupling agent and anhydrous ethanol in the coupling agent solution is independently 1:1~2; The stirring speed is 300~400 rpm and the time is 30~40 min; The drying temperature is 80~100℃ and the time is 6~8h; Each of the dispersants independently includes fatty alcohol polyoxyethylene ether; The mass ratio of the composite filler and dispersant is 1:0.05~0.1.

[0029] This invention also proposes a method for preparing an exposed double-layer interlocking waterproof membrane, which includes the following steps: From top to bottom, the layers are: a multicolored mineral aggregate layer, a high-temperature resistant modified asphalt layer, a first polymer film base layer, a first high-temperature resistant modified asphalt self-adhesive layer, a second polymer film base layer, a second high-temperature resistant modified asphalt self-adhesive layer, and a release layer. The multicolored mineral granule layer shrinks inward by 6-10cm to form an upper overlap edge. A first isolation film is provided on the overlap edge. A 6-10cm overlap joint is provided between the first high-temperature resistant modified asphalt self-adhesive layer and the second polymer film base layer. The overlap joint is located on the opposite side of the overlap edge. A second isolation film covering the surface of the first high-temperature resistant modified asphalt self-adhesive layer is provided inside the overlap joint. The preparation method of the high-temperature resistant modified asphalt layer rubber compound includes the following steps: mixing heavy cross-linked petroleum asphalt with a softener, heating to 140~150℃, adding SMA, and after complete melting, adding SBS and polyolefin, heating to 180~190℃, adding rubber powder, heating to 190~200℃, and after complete melting, adding antioxidant and modified filler A, cooling to 165~185℃ and mixing to obtain the high-temperature resistant modified asphalt layer rubber compound; The preparation methods for the first and second high-temperature resistant modified asphalt self-adhesive layers are independent, including the following steps: mixing heavy-grade petroleum asphalt with a softener, heating to 140~150℃, adding SMA, and after complete melting, adding SBS and granular styrene-butadiene rubber, heating to 180~190℃, adding rubber powder, heating to 190~200℃, and after complete melting, adding oxidized polyethylene wax and a tackifier, stirring evenly, adding modified filler B, cooling to 160~180℃, and mixing to obtain the adhesive for the high-temperature resistant modified asphalt self-adhesive layer; After cooling, the material is measured, trimmed, rolled up, and packaged to obtain an exposed double-layer interlocking waterproof membrane.

[0030] The working principle and beneficial effects of this invention are as follows: In this invention, the rubber compounds of each layer of the dual-layer base roll material are first functionally differentiated. The high-temperature resistant modified asphalt layer is in direct contact with the atmosphere through the colorful mineral granule layer. Through the synergistic effect of SMA, polyolefin, antioxidant and added modified filler, the heat resistance is further improved, avoiding the possible flow of rubber compounds during high summer temperatures. The high-temperature resistant modified asphalt self-adhesive layer further enhances the heat resistance of the self-adhesive material through the action of SMA, oxidized polyethylene wax and added modified fillers, ensuring the overall stability of the self-adhesive material while maintaining its adhesion. In the preparation of the modified filler for the high-temperature modified asphalt layer, wollastonite fiber, talc powder and carbon black are used together. In the modified filler for the first and second high-temperature modified asphalt self-adhesive layers, wollastonite fiber, heavy calcium carbonate powder and carbon black are used together. This can improve the heat aging resistance of the three layers, thereby improving the heat aging resistance of the exposed double-layer interlocking waterproof membrane. Among the three layers of modified fillers, wollastonite fibers have a good reinforcing effect. Their needle-like structure can form a three-dimensional network in the asphalt system, effectively restricting the thermal motion of asphalt molecules and improving the thermal stability of the material. Carbon black can not only absorb ultraviolet rays and prevent asphalt from aging due to photo-oxidation, but also enhance the mechanical properties of asphalt. Talc powder in the modified filler of high-temperature modified asphalt layer has a layered structure, which can increase the internal friction of asphalt, hinder the slippage of molecular chains, and further improve thermal stability. The heavy calcium carbonate powder in the modified filler of the first and second high-temperature resistant modified asphalt self-adhesive layers can adjust the hardness and flexibility of the self-adhesive layers. Different modified fillers are used between different layers. The high-temperature resistant modified asphalt layer mainly undertakes the functions of waterproofing and heat resistance, and requires the unique layered structure provided by talc to enhance internal stability; while the modified asphalt self-adhesive layer focuses more on adhesion and flexibility, so heavy calcium carbonate powder is used. Finally, various colored patterns with a three-dimensional effect are formed by spreading basalt graded sintered sand of several colors through a mold, so that the exposed material remains beautiful when used.
