In addition, although not explicitly recited, every point or individual numerical value between the range endpoints is included in the range. Thus, each point or individual numerical value can be combined as its own lower limit or upper limit with any other point or individual numerical value or with other lower limits or upper limits to form a range not explicitly recited.

[0017] It should be noted that the terms "comprising", "containing", or any other similar words are intended to encompass non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or other elements inherent to such a process, method, article or device. Without more limitations, the elements defined by the statement "comprising" do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0018] Unless otherwise specified, the values of the parameters mentioned in the present application can be measured by various measurement methods commonly used in the art (for example, can be tested according to the methods given in the embodiments of the present application). Unless otherwise specified, the test temperature of each parameter mentioned in the present application is 25℃, and the test pressure is standard atmospheric pressure.

[0019] The above application content of the present application is not intended to describe each disclosed embodiment or each implementation in the present application. The following description illustrates the exemplary embodiments more specifically. In many places throughout the application, guidance is provided by a series of embodiments, which can be used in various combinations. In each instance, the enumeration is only representative of a group, and should not be interpreted as exhaustive.

[0020] In the prior art, when a double-tire base is used as a reinforcing layer to prepare a waterproof roll material, there are generally problems of complex structure and complicated production process. Specifically, current products mostly have a multi-layer structure, and some double-tire base waterproof roll materials even contain three adhesive layers. Due to too many layers of products, the production process needs to be formed multiple times, which not only increases the process complexity, but also reduces the production efficiency. In addition, the selection of the type of adhesive, the matching of hardness and resilience, and the key parameters such as cooling synchronization will significantly affect the final appearance flatness of the roll material. These factors jointly restrict the actual production application of the double-tire base waterproof roll material, and reduce the appearance flatness and various mechanical properties of the double-tire base waterproof roll material, such as tensile strength, elongation, puncture resistance, water impermeability, tear resistance, low-temperature flexibility, roll peeling, and aluminum plate peeling.

[0021] In view of the above problems, the inventors have improved the structure and materials of the double-tire base waterproof roll material.

[0022] The first aspect of the embodiments of the present application provides a prefabricated double-channel waterproof composite roll material, which comprises two layers of tire base layers, two layers of adhesive layers and a release layer arranged in a stacked manner along the thickness direction of the roll material. The two layers of tire base layers and the two layers of adhesive layers are alternately distributed, and the release layer is arranged on the side of the adhesive layer away from the tire base layer. The tire base layer away from the release layer side comprises at least one of a polyvinyl chloride layer and a polyurethane layer, and the tensile strength thereof is ≥300N / 50mm and the thermal shrinkage rate is ≤1.5%. The tire base layer close to the release layer side comprises at least one of a polyester layer, a glass fiber tire layer and a high polymer film layer.

[0023] The structure of the prefabricated double-channel waterproof composite roll material is arranged in a stacked manner along the thickness direction of the roll material, that is, two layers of tire base layers, two layers of adhesive layers and a release layer, the two layers of tire base layers and the two layers of adhesive layers are alternately distributed, and the release layer is arranged on the side of the adhesive layer away from the tire base layer. This simple and efficient hierarchical structure greatly reduces the requirements for process equipment and operating personnel, and can produce double-tire base waterproof roll materials in one forming process, which is convenient and efficient. By controlling the materials of the tire base layer and the release layer, the material of the tire base layer away from the release layer side comprises at least one of a polyvinyl chloride layer and a polyurethane layer, and the tensile strength thereof is ≥300N / 50mm and the thermal shrinkage rate is ≤1.5%. The tire base layer close to the release layer side comprises at least one of a polyester layer, a glass fiber tire layer and a high polymer film layer. The inventors have surprisingly found through a large number of experiments that the use of double-layer tire base with specific materials can effectively improve the appearance flatness of the double-tire base waterproof roll material, and also improve various mechanical properties of the roll material, such as tensile strength, elongation, puncture resistance, water impermeability, tear resistance, low-temperature flexibility, roll peeling performance, and aluminum plate peeling performance.

At the same time, because of the good ductility, it also has a higher improvement on the appearance flatness of the roll material.

[0030] As an example, the tire base layer close to the side of the anti-adhesion layer is also referred to as a second tire base layer or a second tire base reinforcing layer; the tire base layer includes at least one of a polyester layer, a glass fiber tire layer, and a high molecular film layer, which mainly functions to improve the tensile performance, elongation performance, tear strength performance, puncture resistance performance, exposed performance, anti-skid performance, adhesion to post-poured concrete, self-cleaning stain resistance performance of the roll material. At the same time, because of the good ductility, it also has a higher improvement on the appearance flatness of the roll material.

[0031] By controlling the material types of the two tire base layers, the material of the tire base layer away from the side of the anti-adhesion layer includes at least one of a polyvinyl chloride layer and a polyurethane layer, and the tire base layer close to the side of the anti-adhesion layer, the anti-adhesion layer includes at least one of a PE film layer and a PET film layer. When selecting the first reinforcing layer and the second reinforcing layer materials, two materials with similar ductility are selected in combination with the ductility of the materials themselves, and the appearance of the final developed product is more flat.
