Technical Field
[0001] The utility model belongs to the technical field of book packaging, and in particular relates to a PE waterproof coiled material with excellent toughness. Background Art
[0002] Waterproof membrane is mainly used for building walls, roofs, tunnels, roads, landfills, etc. It is a flexible building material product that can be rolled into a roll to resist the seepage of external rainwater and groundwater. As a leak-free connection between the project foundation and the building, it is the first barrier to waterproofing the entire project and plays a vital role in the entire project. PE waterproof membrane is a membrane made of polyethylene resin as raw material.
[0003] The surface of traditional PE waterproofing membranes is prone to wrinkles when they are bonded and laid, making it difficult to adjust and flatten these wrinkles after the membranes are bonded and laid. Under long-term environmental corrosion, the wrinkles of the membranes are often the first to be damaged, thus affecting the waterproof life of the entire membrane. Therefore, a PE waterproofing membrane with excellent toughness is needed to solve the above problem. Summary of the invention
[0004] The purpose of the utility model is to provide a PE waterproofing coiled material with excellent toughness to solve the problems raised in the above background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a PE waterproof coiled material with excellent toughness, comprising a PE layer, a bonding layer is arranged on the lower surface of the PE layer, a fireproof layer is arranged on the upper surface of the PE layer, a plurality of grooves are opened on the PE layer, a rubber strip is fixedly arranged in each of the grooves, and the upper surfaces of the plurality of rubber strips are fixedly connected to the lower surface of the fireproof layer.
[0006] By arranging the rubber strips, the rubber strips perform strip-shaped longitudinal shaping and guiding on the PE layer, so that when the PE layer coil is laid as a whole, the PE layer is supported in the transverse direction by multiple rubber strips and wrinkles will not easily occur during laying. Manual work only requires adjusting and pulling up the wide side of the coil to achieve easy and wrinkle-free laying of the entire coil. The arrangement of the rubber strips can, on the one hand, strengthen the bonding and fixing strength with the fireproof layer, and on the other hand, help to strengthen the overall toughness of the coil. In summary, this helps to ensure the quality of the waterproof bonding of the coil, thereby helping to increase the service life of the coil.
[0007] As a preferred implementation, the rubber strip is semicircular.
[0008] As a preferred implementation, the upper surface of the rubber strip is flush with the upper surface of the PE layer.
[0009] As a preferred embodiment, two transverse adhesive strips and two longitudinal adhesive strips are respectively arranged on the four sides of the adhesive layer.
[0010] As a preferred embodiment, the dimensions of the transverse adhesive strip and the longitudinal adhesive strip are adapted to the overall side dimensions of the PE layer.
[0011] As a preferred embodiment, both the transverse adhesive strip and the longitudinal adhesive strip are provided with adhesive lines.
[0012] By setting up transverse and longitudinal adhesive strips, after a piece of roll material is bonded and laid, the periphery of the roll material can be sealed and bonded using glue through the transverse and longitudinal adhesive strips, which helps to ensure the overall sealing effect of the roll material. After the transverse and longitudinal adhesive strips are used to seal the periphery of the roll material, it will not hinder the adjacent laying of another roll material.
[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] The utility model provides rubber strips. Since the rubber strips guide the PE layer in strip-shaped longitudinal direction, when the PE layer coil is laid as a whole, the PE layer will not be easily wrinkled in the transverse direction due to the support of multiple rubber strips. The whole coil can be laid easily and wrinkle-free only by adjusting and pulling up the wide side of the coil. The provision of the rubber strips can strengthen the bonding and fixing strength with the fireproof layer on the one hand, and on the other hand help to strengthen the overall toughness of the coil. In summary, it helps to ensure the quality of the waterproof bonding of the coil, thereby helping to increase the service life of the coil.
[0015] The utility model provides transverse adhesive strips and longitudinal adhesive strips. After a roll of material is laid, the periphery of the roll of material can be sealed and bonded by using glue through the transverse adhesive strips and longitudinal adhesive strips, thereby helping to ensure the overall sealing effect of the roll of material. After the transverse adhesive strips and longitudinal adhesive strips have sealed the periphery of the roll of material, the adjacent laying of another roll of material is not hindered.
