[0016] As a further technical solution, when the raw material of the anti-sticking layer includes mineral sand, the mineral sand includes one or more of quartz sand, mullite sand, and sintered sand.

[0017] As a further technical solution, the raw materials of the first osmotic reactive adhesive layer, the second osmotic reactive adhesive layer, and the third osmotic reactive adhesive layer each independently include the following components in parts by mass: 30-40 parts of asphalt, 5-15 parts of SBS, 1-3 parts of carboxylated styrene-butadiene rubber, 2-5 parts of tackifier, 3-8 parts of plasticizer, 0.1-1 part of antioxidant, and 25-45 parts of modifier and modified filler; The modifier in the modifier-modified filler meets at least the following two technical characteristics: (1) The molecular structure includes alkyl and phenyl groups; (2) The molecular structure includes epoxy or ether groups.

[0018] The adhesive layer of the present invention's tensile-resistant double-lap polymer membrane-based waterproofing membrane uses asphalt as a base component, providing excellent initial adhesion and an overall bonding matrix. The addition of SBS (styrene-butadiene-styrene block copolymer) and carboxylated styrene-butadiene rubber further improves the adhesive layer's flexibility and ductility, enabling it to adhere closely to the remaining layers, enhancing its bond strength and adhesion to the base surface of the remaining layers and ensuring that the adhesive layer resists detachment and peeling during long-term use. The addition of a tackifier ensures that the adhesive layer maintains excellent bonding properties even in complex environments such as humidity and low temperatures. The addition of a plasticizer not only improves the adhesive layer's flexibility and ductility, but also prevents it from hardening and cracking at low temperatures and softening and flowing at high temperatures. The addition of a filler not only reduces production costs but also adjusts the adhesive layer's hardness and stiffness, enhancing its wear resistance and tensile strength, and extending its service life. The addition of antioxidants effectively inhibits the performance degradation of the adhesive layer caused by oxidation reactions during long-term use, delays the aging process, and maintains the stability of the physical properties and bonding properties of the adhesive layer.

[0019] In the adhesive layer of the tensile-resistant double-lap polymer membrane-based waterproof roll of the present invention, a modifier that simultaneously meets the following two conditions: 1. includes alkyl and phenyl groups in the molecular structure; 2. includes epoxy groups or ether groups in the molecular structure is used to modify the filler, thereby improving the dispersibility of the filler and the compatibility with the base material, thereby achieving the effect of improving the tensile performance of the waterproof roll.

[0020] As a further technical solution, when the molecular structure of the modifier includes an alkyl group, a phenyl group and an epoxy group, the modifier is a composition of epoxysilane, phenylsilane and alkylsilane.

[0021] In the adhesive layer of the tensile-resistant double-lap polymer membrane-based waterproof roll of the present invention, a modifier including alkyl, phenyl and epoxy groups in its molecular structure is used to modify the filler, thereby improving the dispersibility of the filler and the compatibility with the base material. The reason is that: asphalt is a mixture mainly composed of long-chain hydrocarbon compounds with a high carbon content, which contains saturated hydrocarbons and aromatic hydrocarbons. The alkyl part of the modifier can have good compatibility with saturated hydrocarbons, the phenyl part can have good compatibility with aromatic hydrocarbons, and the epoxy part can react with the carboxyl group in carboxyl styrene-butadiene rubber, thereby not only improving the dispersibility of the filler, but also improving the compatibility of the filler with the base material, thereby achieving the effect of improving the tensile performance of the waterproof roll.

[0022] As a further technical solution, the mass ratio of the epoxysilane-modified filler, the phenylsilane-modified filler and the alkylsilane-modified filler is 0.5:1:1.5~4.5, for example, it can be 0.5:1:1.5, 0.5:1:2, 0.5:1:2.5, 0.5:1:3, 0.5:1:3.5, 0.5:1:4, 0.5:1:4.5, etc.

[0025] As a further technical solution, in step A2, the mass ratio of the phenylsilane to anhydrous ethanol is 1:3~5, for example, it can be 1:3, 1:3.1, 1:3.2, 1:3.3, 1:3.4, 1:3.5, 1:3.6, 1:3.7, 1:3.8, 1:3.9, 1:4, 1:4.5, 1:5, etc.; the mass ratio of the phenylsilane to the filler is 1:10~20, for example, it can be 1:10, 1:11, 1:12, 1:13, 1:14, 1:15, 1:16, 1:17, 1:18, 1:19, 1:20, etc.

[0026] As a further technical solution, in step A3, the mass ratio of the alkylsilane to anhydrous ethanol is 1:3~5, for example, it can be 1:3, 1:3.1, 1:3.2, 1:3.3, 1:3.4, 1:3.5, 1:3.6, 1:3.7, 1:3.8, 1:3.9, 1:4, 1:4.5, 1:5, etc.; the mass ratio of the alkylsilane to the filler is 1:10~20, for example, it can be 1:10, 1:11, 1:12, 1:13, 1:14, 1:15, 1:16, 1:17, 1:18, 1:19, 1:20, etc.

[0029] In the adhesive layer of the tensile double-lapped polymer membrane-based waterproofing membrane of the present invention, the alkyl silane can be any one or more conventional silanes containing an alkyl group, for example, KH-516 1,2-Bis(trimethoxysilyl)ethane, KH-5261,2-Bis(triethoxysilyl)ethane, KH-131 methyltrimethoxysilane, KH-132 methyltriethoxysilane, KH-2121 dimethyldimethoxysilane, KH-2122 dimethyldiethoxysilane, KH-313 propyltrimethoxysilane, KH-330 propyltriethoxysilane, KH-2321 diisopropyldimethoxysilane, KH-242 isobutyltriethoxysilane, KH-2421 diisobutyldimethoxysilane, KH-2521 dicyclopentyldimethoxysilane, KH-480 n-hexyltriethoxysilane, KH-481 cyclohexyltrimethoxysilane, KH-580 One or more of octyltriethoxysilane, KH-581 octyltrimethoxysilane, KH-2581 isooctyltrimethoxysilane, KH-2580 isooctyltriethoxysilane, KH-681 n-decyltrimethoxysilane, KH-3112 n-dodecyltrimethoxysilane, KH-3113 n-dodecyltriethoxysilane, KH-1631 hexadecyltrimethoxysilane, KH-1632 hexadecyltriethoxysilane, KH-1831 octadecyltrimethoxysilane, KH-1832 octadecyltriethoxysilane, KH-1821 octadecylmethyldimethoxysilane, and KH-1822 octadecylmethyldiethoxysilane, preferably KH-581.

[0030] In the adhesive layer of the tensile-resistant double-lap polymer membrane-based waterproof roll of the present invention, when the molecular structure of the modifier includes an alkyl group, a phenyl group, and an ether group, the modifier can be any one or more compounds containing an alkyl group, a phenyl group, and an ether group, for example, it can be one or both of 2-octadecyl-1,4-dimethoxybenzene and 4-n-octadecyloxybiphenyl, preferably 4-n-octadecyloxybiphenyl (CAS No. 376609-78-8).

[0031] In the adhesive layer of the tensile-resistant double-lap polymer membrane-based waterproof roll of the present invention, a modifier including alkyl, phenyl and ether groups in its molecular structure is used to modify the filler, thereby improving the dispersibility of the filler and the compatibility with the base material. The reason is that: asphalt is a mixture mainly of long-chain hydrocarbon compounds with a high carbon content, which contains saturated hydrocarbons and aromatic hydrocarbons. The alkyl part of the modifier can have good compatibility with saturated hydrocarbons, the phenyl part can have good compatibility with aromatic hydrocarbons, and the ether parts cannot form hydrogen bonds. However, it can not only form hydrogen bonds with the hydroxyl groups on the surface of the filler and thus be adsorbed on the surface of the filler, but also form hydrogen bonds with the carboxyl groups in carboxyl styrene-butadiene rubber, thereby not only improving the dispersibility of the filler, but also improving the compatibility of the filler with the base material, thereby achieving the effect of improving the tensile performance of the waterproof roll.

[0036] As a further technical solution, the preparation methods of the first permeation reaction adhesive layer, the second permeation reaction adhesive layer, and the third permeation reaction adhesive layer independently include the following steps: heating the asphalt to 180~190℃, mixing it evenly with carboxylated styrene-butadiene rubber, SBS, and modifier-modified filler, cooling it to 135~140℃, adding the remaining components and mixing.

[0037] During the preparation process of the adhesive layer of the tensile-resistant double-lap polymer membrane-based waterproof roll material of the present invention, the asphalt is first heated to 180-190° C. Within this temperature range, the asphalt can be in a molten flow state and can be fully mixed with carboxylated styrene-butadiene rubber, SBS, and a modifier-modified filler. The remaining components are then added after the temperature is lowered to 135-140° C., which can effectively prevent high temperature from damaging the performance of various functional additives and ensure that various functional additives can fully play their role.

[0038] The working principle and beneficial effects of the present invention are: The present invention provides a tensile-resistant double-lapped polymer membrane-based waterproof membrane, which realizes a "double-occlusal" structure when the waterproof membrane is overlapped by providing a first overlapped interface and a second overlapped interface on both sides of the second permeable reactive adhesive layer.

[0052] Performance testing: (1) After overlapping the waterproof membranes with a thickness of 3 mm obtained in Example 8 and Comparative Example 1, the peel strength between the membranes (overlapping edge) was tested with reference to the method in GB / T 23457-2017, and the adhesion (long edge) of the overlapping edges in shear state was tested with reference to the method in GB 12953-2003. The test results are recorded in Table 1.

[0053] Table 1 Peel strength and adhesion test results

[0054] As can be seen from Table 1, compared with Comparative Example 1, the peel strength between the coils and the adhesion in the shear state of the overlapping edges of Example 8 are higher. At the same time, the peel strength remains at 100% after immersion in water. This shows that the present invention realizes a "double-bite" structure during overlap by providing a first overlapping interface and a second overlapping interface on both sides of the second permeable reactive adhesive layer, thereby improving the peel strength and adhesion between the coils while ensuring the waterproof performance of the overlapping interface.

[0055] (2) The waterproof membranes with a thickness of 3 mm obtained in Examples 1 to 8 were tested for tensile properties according to the method in GB / T 23457-2017 "Pre-laid waterproof membranes". The maximum longitudinal tensile force and the maximum transverse tensile force were both the average values of 5 specimens as the final test results. The test results are recorded in Table 2.

[0056] Table 2 Tensile performance test results of waterproof membrane

[0057] As can be seen from Table 2, compared with Example 8, the maximum longitudinal tensile force and the maximum transverse tensile force of the waterproof membrane obtained in Examples 1 to 7 are higher, indicating that the use of a modifier that simultaneously meets the following two conditions: ① including an alkyl group and a phenyl group in the molecular structure; ② including an epoxy group or an ether group in the molecular structure to modify the filler improves the tensile properties of the waterproof membrane.
