Technical Field

[0001] The utility model relates to the field of waterproof coiled materials, in particular to an anti-aging composite waterproof coiled material. Background Art

[0002] Waterproof membrane is mainly used in building walls, roofs, tunnels, roads and landfills. It is a flexible building material product that can be rolled into a roll to prevent external rainwater or groundwater leakage. As a leak-proof 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.

[0003] Composite waterproof membranes are made of films made of multiple materials stacked and bonded together. During long-term use, the composite membrane shrinks and cracks under temperature changes. In addition to delamination and cracking, it may even break as a whole, affecting its barrier effect. Therefore, an anti-aging composite waterproof membrane is proposed. Utility Model Content

[0021] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0022] In the drawings, the same reference numerals all refer to the same components.

[0023] Example 1

[0024] like Figure 1-3 As shown, the utility model provides an anti-aging composite waterproof roll material, including a composite waterproof cloth 1, a stretch cloth 2 and an edge strip 3, wherein the number of the composite waterproof cloth 1 and the stretch cloth 2 are both multiple, and the multiple composite waterproof cloths 1 are evenly spaced from left to right. Two adjacent composite waterproof cloths 1 are fixedly connected by the stretch cloth 2, and the stretch cloth 2 is used to be stretched when the composite waterproof cloth 1 shrinks due to temperature changes;

[0025] In this embodiment, the composite waterproof cloth 1 includes a matte layer 11, a waterproof layer 12, a connecting layer 13, an insulating layer 14, a butt joint layer 15 and a contact layer 16. The matte layer 11, the waterproof layer 12, the connecting layer 13, the insulating layer 14, the butt joint layer 15 and the contact layer 16 are bonded together in sequence from top to bottom. The matte layer 11 is a biaxially oriented polypropylene film. When the roll material is laid in a location such as a roof, it can reduce reflection under sunlight, which is beneficial to reducing light pollution problems. The waterproof layer 12 is a polyvinyl chloride layer. The connecting layer 13 and the butt joint layer 15 are both made of polyurethane with good elasticity. When the temperature changes, the upper and lower connected parts of the two are affected by the temperature and shrink, which will stretch the connecting layer 13 and the butt joint layer 15. In this way, the problem of delamination and cracking of the roll material is not easy to occur. The insulating layer 14 is a polypropylene foam layer. The polypropylene foam has a good thermal insulation effect and is very suitable for thermal insulation on the top of the building. The contact layer 16 is made of glass fiber cloth. The flame retardant effect of glass fiber is excellent, which can reduce the fire risk of the roll material.

[0026] It is particularly noted that there are two edge strips 3, which are respectively covered on the front and back sides of the composite waterproof cloth 1 and the stretch cloth 2. The edge strips 3 are U-shaped and are used to protect the cross-sections of the front and back sides of the composite waterproof cloth 1 and the stretch cloth 2, and minimize the contact between the waterproof layer 12, the connecting layer 13, the thermal insulation layer 14 and the docking layer 15 inside the composite waterproof cloth 1 and the air.

[0027] In this embodiment, the telescopic fabric 2 includes a telescopic layer 21, the left and right sides of the telescopic layer 21 are respectively bonded to the composite waterproof fabric 1, and the top and bottom of the telescopic layer 21 are bonded with a laminating fabric 22. The left and right sides of the laminating fabric 22 extend to the surface of the telescopic layer 21 and are bonded to its surface. The telescopic layer 21 and the laminating fabric 22 are both polyurethane fabrics.

[0028] In summary, the present invention provides a stretchable cloth 2. When the composite waterproof cloth 1 shrinks during temperature changes, the shrinkage force generated by the multiple narrower composite waterproof cloths 1 will stretch the stretchable cloth 2 with better elasticity without breaking the composite waterproof cloth 1 as a whole. By providing a connecting layer 13 and a docking layer 15 made of polyurethane, when layers of different materials shrink to different degrees due to temperature changes, the connecting layer 13 and the docking layer 15 with better elasticity are stretched, and it is not easy for the layers to separate and crack. By providing a matte layer 11 made of a biaxially oriented polypropylene film, the matte layer 11 is not easy to reflect sunlight, and it is not easy to generate light pollution when the roll material is laid on the surface of a building.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
