Description

Technical Field

[0001] The utility model relates to the technical field of waterproof coiled materials, in particular to a glass fiber composite polyester felt exposed asphalt waterproof coiled material. Background Art

[0002] The carcasses used in SBS waterproof coiled materials are all long fiber polyester felts. During the production process, the carcass is subjected to a large longitudinal tensile force and is longitudinally stretched. After coating with glue, shaping, and coiling, the carcass is still in a stretched state, so shrinkage stress is generated. At room temperature, when the temperature is low and the asphalt glue is hard, the coiled material will not shrink; after construction in hot summer and high-temperature environments, the surface temperature of the coiled material rises, the asphalt glue softens accordingly, the peel strength drops sharply, and the bonding strength of the glue layer is not sufficient to resist the carcass shrinkage stress, ultimately resulting in the shrinkage of the coiled material and leakage risk at the lap joint. Content of the Utility Model

[0022] The present utility model will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0023] Please refer to Figures 1-4 , this application provides a fiberglass composite polyester felt exposed asphalt waterproofing coil, comprising:

[0024] A base layer 1, including a polyester felt layer 10 and at least one fiberglass tensile reinforcement 11 compounded on the polyester felt layer 10, and at least one fiberglass tensile reinforcement 11 extends along the length direction of the base layer;

[0025] A lower adhesive layer 2, disposed on the lower surface of the base layer 1.

[0026] Specifically, as a specific implementation manner, referring to Figure 1 , the specific structure of the waterproofing coil provided by this application is: including a base layer 1, wherein the base layer adopts a polyester felt layer 10 and at least one fiberglass tensile reinforcement 11 compounded on the polyester felt layer. The fiberglass tensile reinforcement 11 is made of glass fiber. The polyester felt layer 10 and the fiberglass reinforcement can be bonded and compounded together with an adhesive. By longitudinally strengthening the polyester felt layer with glass fiber, the longitudinal tensile strength of the base layer can be improved, and during the production process of the waterproofing coil, the longitudinal deformation amount of the base layer can be reduced, so that the shrinkage stress of the waterproofing coil is reduced, and the shrinkage amount of the waterproofing coil at high temperature is reduced, thereby reducing the risk of leakage at the lap joint due to excessive shrinkage of the waterproofing coil; wherein the longitudinal direction is the winding direction of the waterproofing coil, that is, the length direction of the waterproofing coil. In this application, only fiberglass tensile reinforcements are extended and arranged in the length direction of the base layer, which can not only reduce the tensile deformation amount of the base layer in the length direction but also reduce the usage amount of the fiberglass reinforcement, reducing the manufacturing cost.

[0027] Furthermore, as a preferred implementation manner, the fiberglass tensile reinforcement 11 is made of single or multiple glass fibers, and the fiberglass tensile reinforcement 11 includes multiple pieces. The multiple fiberglass tensile reinforcements 11 are evenly spaced along the width direction of the base layer. Specifically, the width direction of the base layer is the direction perpendicular to the longitudinal direction. The fiberglass tensile reinforcement is adhesively fixed and compounded with the polyester felt layer 10 through an adhesive. By evenly spacing and arranging multiple fiberglass tensile reinforcements 11 on the base layer, the fiberglass tensile reinforcements 11 are evenly distributed, ensuring that each part of the base layer has tensile strength, and can further improve the overall tensile strength of the base layer and reduce the tensile deformation amount of the base layer.

[0028] Further, as a specific implementation manner, in the specific implementation manner, each fiberglass tensile rib 11 is made of single or multiple non-alkali glass fibers with a radius of 10 - 13 um. As a specific implementation manner, the distance between adjacent two fiberglass tensile ribs 11 is 8 mm - 12 mm. In the specific implementation manner, the width dimension of the waterproof coiled material is generally about 1 meter - 2 meters, and the specific interval distance of the fiberglass reinforcing ribs 11 on the base layer is any value among 8 mm, 9 mm, 10 mm, 11 mm, and 12 mm.

[0029] Further, as another implementation manner, referring to Figures 2-4 , in some implementation manners, the fiberglass tensile rib 11 adopts a strip-shaped layered structure woven from glass fibers. In this implementation manner, the fiberglass tensile rib 11 is also adhesively connected using an adhesive to achieve the effect of enhancing the longitudinal tensile strength of the base layer. As a preferred implementation manner, in this implementation manner, the fiberglass tensile rib 11 also includes multiple strips arranged at intervals along the width direction of the base layer; the specific components of the adhesive are: acrylic acid: 30 - 40%; unsaturated resin: 20 - 35%; vinyl acetate: 20 - 40%; coupling agent: 0.3 - 0.6%.

[0030] Specifically, in some implementation manners, referring to Figure 2 、 Figure 3 , when the fiberglass tensile rib 11 adopts a strip-shaped layered structure woven from glass fibers, a groove for accommodating the fiberglass tensile rib 11 is also provided in the polyester felt layer 10. By providing the groove, the fiberglass tensile rib 11 can be accommodated inside the groove, ensuring the flatness of the base layer and facilitating the subsequent coating of the upper adhesive layer 31 and the lower adhesive layer 2.

[0031] Further, as a preferred implementation manner, referring to Figures 1-3 , it further includes a protective layer 3, which is provided on the side of the base layer 1 opposite to the lower adhesive layer 2.

[0032] Specifically, in this application, by providing the protective layer 3 on the waterproof coiled material, the external ultraviolet rays are isolated by the protective layer, thereby reducing the weathering speed of the waterproof coiled material and increasing the service life.

[0033] Further, as a specific implementation manner, the protective layer 3 includes an upper adhesive layer 31 provided on the base layer 1 and a sintered sand layer 32 adhesively provided on the upper adhesive layer.

[0034] Specifically, the specific structure of the protective layer 3 is as follows: it includes an adhesive layer 31 provided on the surface of the base layer and a sintered sand layer 32 adhered to the adhesive layer 31. Among them, the adhesive layer 31 uses SBS asphalt glue, and the sintered sand layer 32 is formed by adhering white sintered sand grains to the adhesive layer 31. The white sintered sand layer can effectively reflect ultraviolet rays. Compared with ordinary rock slabs and black sand, it can reduce the surface temperature of the coil, enable the adhesive layer 31 to isolate ultraviolet rays, reduce weathering, and improve the overall performance of the waterproof coil.

[0035] Further, as a specific implementation manner, the particle size of the sand and gravel in the sintered sand layer 32 is 30 mesh - 60 mesh.

[0036] Further, as a specific implementation manner, referring to Figures 1-3 , an isolation film layer 4 is provided on the side of the lower adhesive layer 2 away from the base layer. Specifically, the lower adhesive layer uses SBS asphalt glue for bonding the waterproof coil to the base surface to be protected, and the isolation film layer 4 uses a PE film for protecting and isolating the lower adhesive layer to prevent the waterproof coil from sticking during storage.

[0037] Further, referring to Figure 6 、 Figure 7 , the production process of the fiberglass composite polyester felt exposed asphalt waterproof coil provided by this application is as follows:

[0038] Referring to Figure 7 , the production process flow is as follows:

[0039] a) Turn on the pre-impregnating glue tank and SBS glue tank heating systems 2 hours in advance;

[0040] b) Open the valve of the discharge port of the batching tank, start the oil pump, pump the prepared super SBS glue into the SBS glue tank, and turn on the self-circulation;

[0041] c) Open the valve of the discharge port of the pre-impregnating glue tank, start the glue pump, put the prepared pre-impregnating glue into the pre-impregnating glue tank, and turn on the self-circulation and the large circulation with the pre-impregnating glue tank;

[0042] d) Turn on the tire base drying device;

[0043] e) Start the production line. According to the production process flow chart, pass the fiberglass composite polyester felt carcass through the drying device, pre-impregnating glue tank, and SBS glue tank in sequence. Use the reduction gear to drive the pressure roller, pull out the carcass impregnated with the coating material, adjust the roll distance to obtain the required thickness, and adjust the distance between the fixed calender rolls.

[0044] f) Apply the lower surface isolation film, adjust the tension of the isolation film to ensure no wrinkles or deformation;

[0045] g) Turn on the sand spreading device and evenly spread the sintered sand on the upper surface of the coil through the sand spreader;

[0046] h) Then, through shaping, traction conveying, metering, coiling, packaging, inspection and warehousing.

[0047] i) Before stopping the machine, empty the glue in the pre-impregnated glue tank and SBS glue tank or return it to the tank, turn off the heating systems for oil dipping and glue coating, turn off the traction system, turn off the cooling water, turn off the sand spreading system, and clean the site.

[0048] Example Two

[0049] This application provides a fiberglass composite polyester felt exposed asphalt waterproofing coil, including a base layer 1, a lower glue layer 2 disposed on the base layer 1, and a protective layer 3 located on the base layer. The protective layer includes an upper glue layer 31 and a white sintered sand layer 32. Both the upper glue layer and the lower glue layer are made of SBS asphalt glue. A separator film layer 4 is disposed below the lower glue layer 2. Refer to Figure 5 . Different from Example One, along the length direction of the waterproofing coil, an extended base layer 5 is further disposed at one end of the base layer. The extended base layer 5 is on the side of the base layer close to the lower glue layer 2. There is an overlapping edge section between the extended base layer and the base layer. Along the length direction of the base layer, the overlapping length between the base layer and the extended base layer 5 is between 50 cm and 1 m. The overlapping area between the base layer and the extended base layer 5 is bonded and connected by an intermediate bonding layer 51. The intermediate bonding layer 51 is made of SBS asphalt glue. The lower glue layer 2 covers the side of the extended base layer 5 opposite to the base layer 1. Above the end of the extended base layer 5 extending out of the base layer, a deformation bonding layer 52 is covered. The deformation bonding layer 52 and the intermediate bonding layer 51 are made of the same SBS asphalt glue. The sintered sand layer 32 covers the deformation bonding layer 52. The length of the intermediate bonding layer 51 extending out of the base layer is greater than the overlapping length with the base layer, between 1 m and 1.2 m. The viscosities of the deformation bonding layer 52 and the intermediate bonding layer 51 are less than that of the lower glue layer. In this example, fiberglass tensile ribs 11 are also disposed in the base layer 1. The thickness of the extended base layer 5 is less than that of the base layer 1, and the extended base layer 5 is also made of a polyester felt layer composite with fiberglass tensile ribs. It can be understood that although the fiberglass tensile ribs 11 are provided, the base layer will inevitably undergo a certain amount of tensile deformation in the length direction. Through the above setting method in this example, when constructing the construction surface with the waterproofing coil, the lower glue layer 2 is in contact with and bonded to the construction surface. When the base layer shrinks due to heat, the intermediate bonding layer 51 between the extended base layer 5 and the base layer can first undergo deformation, and relative sliding occurs between the base layer and the extended base layer, thereby compensating for the shrinkage amount of the base layer. The deformation bonding layer 52 flows and covers the upper surfaces of the base layer and the extended base layer after being heated to achieve the anti-leakage effect, thereby reducing the risk of separation and leakage at the overlapping part of the waterproofing coil layer due to retraction.

[0050] Obviously, the above embodiments are merely examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the creation of the present utility model.
