Abstract
Description
Technical Field
[0001] The present application relates to the technical field of waterproof roll materials, and in particular to a high temperature resistant self-adhesive polymer waterproof roll material. Background Art
[0002] High temperature resistant self-adhesive polymer waterproofing membrane is a waterproofing material with high heat resistance and self-adhesive function, usually made of polymer modified asphalt or polymer materials. High temperature resistant self-adhesive polymer waterproofing membrane has good bonding and anti-aging properties, and can maintain good waterproofing effect in high temperature environment.
[0003] In simple terms, high temperature resistant self-adhesive polymer waterproofing membrane generally includes a membrane body, a separation membrane and an adhesive layer. The membrane body is the part that is laid inside the building and actually plays a waterproofing role. The separation membrane plays the role of protecting the adhesive layer and the membrane body. The adhesive layer is between the membrane body and the separation membrane and plays the role of connecting the membrane body and the separation membrane. The operator removes the protection of the adhesive layer by tearing off the outer layer of the separation membrane, so that the waterproofing membrane can be laid and fixed through the adhesive layer.
[0004] The adhesive layer on some waterproof membranes is formed by applying adhesive to the upper surface of the membrane body and undergoing a certain solidification and curing process. After long-term exposure to light, oxidation and temperature, there is a possibility that the adhesive layer and the membrane body will separate. Utility Model Content
[0005] In order to reduce the possibility of separation between the adhesive layer and the roll body, the present application provides a high temperature resistant self-adhesive polymer waterproof roll.
[0006] The present application provides a high temperature resistant self-adhesive polymer waterproof membrane, which adopts the following technical solution:
[0007] A high-temperature resistant self-adhesive polymer waterproof roll material comprises a roll body and an isolation film, wherein an adhesive layer is arranged between the roll body and the isolation film, one side of the adhesive layer is adhered to the roll body, and the other side of the adhesive layer is adhered to the isolation film, an embedding protrusion is arranged on the side of the adhesive layer close to the roll body, and a groove is opened on the roll body for accommodating the embedding protrusion.
[0008] Through the above technical solution, after the operator applies the adhesive to the upper surface of the coil body, the adhesive can flow into the groove one under the action of gravity, and the adhesive can gradually solidify in the groove one of the coil body to form an embedded protrusion one. There is a certain friction between the outer wall of the embedded protrusion one and the inner wall of the groove one, which increases the difficulty of separation between the adhesive layer and the coil body, thereby reducing the possibility of separation between the adhesive layer and the coil body.
[0009] In a preferred example, the utility model can be further configured as follows: an embedding protrusion 2 is provided at the bottom of the embedding protrusion 1, the area of the local cross-section of the embedding protrusion 2 is larger than the area of the cross-section of the embedding protrusion 1, and a groove 2 for accommodating the embedding protrusion 2 is provided in the coil body, and the groove 2 and the groove 1 are connected to each other.
[0010] Through the above technical solution, the adhesive can flow into groove one and groove two under the action of gravity, and gradually solidify in groove one and groove two to form embedded protrusion one and embedded protrusion two respectively. Since the area of the local cross-section of embedded protrusion two is larger than the area of the cross-section of embedded protrusion one, under the anchoring effect of embedded protrusion two, the possibility of separation between the adhesive layer and the roll body is further reduced.
[0011] In a preferred example, the utility model can be further configured as follows: a lap joint 1 is provided at one end of the coil body, the top surface of the lap joint 1 is flush with the top surface of the coil body, and a lap joint 2 is provided at the other end of the coil body, the bottom surface of the lap joint 2 is flush with the bottom surface of the coil body.
[0012] When the distance of the laying site is long, several rolls of material need to be spliced together so that the rolls can fully cover the required laying site. Through the above technical solution, when laying the next roll of material at one end of the previous roll of material, the overlapping portion 1 of one of the rolls of material is overlapped on the overlapping portion 2 of the other roll of material, which reduces the possibility of stacking bulges of the waterproof rolls, thereby improving the flatness of the laying of the waterproof rolls.
[0013] In a preferred example, the present invention can be further configured as follows: an adhesive portion 1 is provided on a side of the overlapping portion 1 away from the coil body.
[0014] Through the above technical solution, between two adjacent coiled material bodies, one coiled material body and the other coiled material body are connected via an adhesive portion, thereby improving the integrity between the two adjacent coiled material bodies.
[0015] In a preferred example, the present invention can be further configured as follows: a bonding portion 2 is provided on the bottom surface of the overlapping portion 1.
[0016] Through the above technical solution, since the bottom surface of the overlapping portion 1 is provided with the bonding portion 2, the overlapping portion 1 and the overlapping portion 2 can be connected through the bonding portion 2, thereby further improving the integrity between the two adjacent coil bodies.
[0017] In a preferred example, the present invention can be further configured as follows: the sum of the thicknesses of the second bonding portion, the first overlapping portion, and the second overlapping portion is equal to the thickness of the coil body.
[0018] Through the above technical solution, since the sum of the thicknesses of bonding portion 2, overlapping portion 1 and overlapping portion 2 is equal to the thickness of the roll material body, after overlapping portion 1 and overlapping portion 2 are bonded by bonding portion 2, the flatness of the laying of the two adjacent roll material bodies is further improved.
[0019] In a preferred example, the utility model can be further configured as follows: it also includes an edge banding strip, the length of the edge banding strip is equal to the length of the overlapping portion 1, and the edge banding strip is bonded to the bonding portion 2.
[0020] Through the above technical solution, if the roll material body can just extend to the end of the laying site, the operator places the edge banding strip under the overlapping part one and makes the edge banding strip adhere to the overlapping part one through the adhesive part two. The edge banding strip provides support for the overlapping part one to reduce the amount of deformation of the overlapping part one downward, thereby improving the waterproof performance.
[0021] In a preferred example, the utility model can be further configured as follows: the sum of the edge banding strip, the second bonding portion, and the first overlapping portion is equal to the thickness of the coil body.
[0022] Through the above technical solution, since the sum of the thickness of the edge banding strip, the thickness of the bonding part two, and the thickness of the overlapping part one is equal to the thickness of the roll body, therefore, after the overlapping part one and the edge banding strip are bonded by the bonding part two, the flatness of the laying of the two adjacent roll bodies is further improved.
[0023] In summary, the utility model includes the following beneficial technical effects:
[0024] 1. Under the anchoring effect of the embedded protrusion 2 and the reinforcement effect of the embedded protrusion 1, the adhesive layer increases the difficulty of separation between the adhesive layer and the coil body, thereby reducing the possibility of separation between the adhesive layer and the coil body;
[0025] 2. Two adjacent roll materials are connected by overlapping part 1 and overlapping part 2, which reduces the possibility of stacking bulges of the waterproof roll materials, thereby improving the flatness of the laying of the waterproof roll materials. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following is combined with Figure 1 -Attached Figure 4 This application is described in further detail.
[0033] The embodiments of the present application disclose a high temperature resistant self-adhesive polymer waterproof roll.
[0034] Refer to the attached Figure 1 and attached Figure 2 As shown, a high temperature resistant self-adhesive polymer waterproofing membrane comprises a membrane body 1 and a separator 2. The membrane body 1 is made of a high temperature resistant polymer material. An adhesive layer 3 is provided between the membrane body 1 and the separator 2. The adhesive layer 3 is formed by curing the adhesive coated on the upper surface of the membrane body 1. The two sides of the adhesive layer 3 are respectively bonded to the upper surface of the membrane body 1 and the lower surface of the separator 2.
[0035] Refer to the attached Figure 2 and attached Figure 3 As shown, a plurality of mutually parallel embedding protrusions 31 are arranged on one side of the adhesive layer 3 close to the coil body 1. The embedding protrusion 31 is in the shape of an elongated strip, and the longitudinal section of the embedding protrusion 31 is in the shape of a rectangle. A plurality of grooves 11 for accommodating the embedding protrusion 31 are provided on the coil body 1. The plurality of grooves 11 and the plurality of embedding protrusions 31 are arranged in a one-to-one correspondence, and the inner wall of the groove 11 and the embedding protrusion 31 fit each other.
[0036] Refer to the attached Figure 2 and attached Figure 3As shown, each embedded protrusion 1 31 is provided with an embedded protrusion 2 32 at the bottom, and the longitudinal section of the embedded protrusion 2 32 is elliptical. The embedded protrusion 1 31 and the embedded protrusion 2 32 are integrally formed and are both formed by curing an adhesive. The area of the local cross section of the embedded protrusion 2 32 is larger than the area of the cross section of the embedded protrusion 1 31. The coil body 1 is provided with a groove 2 12 for accommodating the embedded protrusion 2 32. The inner wall of the groove 2 12 and the embedded protrusion 2 32 fit each other, and the groove 2 12 and the groove 1 11 are connected to each other.
[0037] After the operator applies the adhesive to the upper surface of the coil body 1, the adhesive can flow into the groove 11 and the groove 2 12 in sequence under the action of gravity, and the adhesive gradually accumulates from bottom to top, and finally solidifies to form the adhesive layer 3, the embedded protrusion 1 31 and the embedded protrusion 2 32. Under the anchoring effect of the embedded protrusion 2 32 and the reinforcement effect of the embedded protrusion 1 31, the adhesive layer 3 increases the difficulty of separation between the adhesive layer 3 and the coil body 1, thereby reducing the possibility of separation between the adhesive layer 3 and the coil body 1.
[0038] Refer to the attached Figure 2 and attached Figure 4 As shown, one end of the coil body 1 is provided with an overlap part 101, the top surface of the overlap part 101 is flush with the top surface of the coil body 1, and the other end of the coil body 1 is provided with an overlap part 2 102, the overlap part 2 102, the overlap part 101 and the coil body 1 are integrally formed, the bottom surface of the overlap part 2 102 is flush with the bottom surface of the coil body 1, and the thickness of the overlap part 101 is equal to the thickness of the overlap part 2 102. Two adjacent coil bodies 1 are overlapped and connected by the overlap part 101 and the overlap part 2 102, which reduces the possibility of stacking bulges of adjacent coil bodies 1, thereby improving the flatness of the waterproof coil laying.
[0039] Refer to the attached Figure 2 and attached Figure 4 As shown, a bonding part 1 41 is provided on the side of the overlap part 101 away from the coil body 1, so as to facilitate bonding of two adjacent coil bodies 1 and improve the integrity between the two adjacent coil bodies 1. A bonding part 2 42 is provided on the bottom surface of the overlap part 101, so as to facilitate bonding of the overlap part 101 and the overlap part 2 102 on the adjacent coil body 1. The bonding part 1 41, the bonding part 2 42 and the bonding layer 3 are integrally formed and are all formed by curing the adhesive.
[0040] Refer to the attached Figure 2 and attached Figure 4 As shown, the sum of the thicknesses of the bonding portion 2 42 , the overlapping portion 1 101 , and the overlapping portion 2 102 is consistent with the thickness of the coil body 1 . Therefore, after the overlapping portion 1 101 and the overlapping portion 2 102 are bonded by the bonding portion 2 42 , the flatness of the laying of the two adjacent coil bodies 1 is further improved.
[0041] Refer to the attached Figure 2 and attached Figure 4 As shown, the waterproof membrane further includes an edge band 5, the length of the edge band 5 is equal to the length of the overlapping portion 101, the edge band 5 is bonded to the bonding portion 2 42, and the sum of the edge band 5, the bonding portion 2 42, and the overlapping portion 101 is equal to the thickness of the membrane body 1. The thickness of the edge band 5 is equal to the thickness of the overlapping portion 101.
[0042] The operator places the edge banding strip 5 under the overlapping portion 101 and adheres the edge banding strip 5 to the overlapping portion 101 through the adhesive portion 2 42, so that the roll body 1 can be suitable for extending to the end of the laying site. At this time, the edge banding strip 5 provides support for the overlapping portion 101 to reduce the deformation of the overlapping portion 101 downward, so as to improve the waterproof performance.
[0043] The implementation principle of this embodiment is as follows: after the operator applies the adhesive to the upper surface of the coil body 1, the adhesive flows into the groove 11 and the groove 2 12, and gradually solidifies to form the adhesive layer 3, the embedded protrusion 1 31 and the embedded protrusion 2 32. Under the anchoring effect of the embedded protrusion 2 32 and the reinforcement effect of the embedded protrusion 1 31, the adhesive layer 3 increases the difficulty of separation between the adhesive layer 3 and the coil body 1, thereby reducing the possibility of separation between the adhesive layer 3 and the coil body 1.
[0044] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application in sequence. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
