Background Art

[0002] Waterproofing membrane is a rollable sheet-like waterproof material, mainly used in building walls, roofs, tunnels and roads to prevent leakage of rainwater or groundwater. Existing waterproofing membranes mainly include surface layer, middle layer and base layer. The surface layer is mainly responsible for preventing mechanical damage, ultraviolet radiation, and blocking external damage such as water flow. The middle layer is the core part of the waterproofing membrane, responsible for preventing water penetration, and also has the function of preventing thermal aging and ozone aging. The base layer is the foundation of the waterproofing membrane, providing the main physical strength support for the entire membrane. However, the surface layer of the existing waterproof membrane cannot pre-absorb or treat the rainwater or groundwater it contacts, and the retention of water in the surface layer can easily cause erosion and damage to it, and there is a high possibility of water seepage; the middle layer of the existing waterproof membrane is generally composed of materials such as asphalt, which has poor thermal insulation performance and is prone to softening, flowing or deforming in a high temperature environment, and cannot maintain a stable waterproof effect for a long time; at the same time, the overlap method of the existing waterproof membrane is generally single-sided welding, and the overlap area is prone to warping and separation, resulting in gaps between the membranes or between the membranes and the base layer, which cannot effectively prevent water penetration, resulting in water seepage and leakage, and poor waterproof performance.

[0051] The present invention provides a method for preparing a heat-stable high-performance waterproof roll material (1), comprising the following steps:

[0052] The polymer absorbent resin sponge and the fine fiber net are combined by an adhesive to form a double-layer structure adsorption layer (2), the thickness of which is controlled between 10 μm and 20 μm, and a plurality of air-permeable gaps are evenly cut in the circumferential direction of the edge of the adsorption layer (2) using laser cutting technology to promote water evaporation, moisture discharge and air circulation;

[0053] High-density polypropylene is used as the substrate of the surface layer (3), and the thickness is controlled to be between 5 μm and 10 μm. Before the surface layer (3) is bonded to the adsorption layer (2) by an adhesive, the surface of the high-density polypropylene is subjected to corona treatment or flame treatment to improve the adhesion with the adhesive;

[0054] Preferably, a metal coating layer or a metal foil film layer is formed on the surface layer (3) by electroplating, spraying or pasting as a light reflecting layer;

[0055] Using polyester non-woven fabric as the substrate of the middle layer (4), evenly brushing modified asphalt on both sides of the polyester non-woven fabric, and evenly mixing heat-resistant particles such as diamond powder or ceramic powder into the asphalt to slow down heat transfer, and controlling the thickness of the middle layer (4) to be between 15 μm and 30 μm;

[0059] The adsorption layer (2), the surface layer (3), the middle layer (4) and the base layer (5) are preheated to eliminate internal stress and improve interlayer bonding strength; the adsorption layer (2), the surface layer (3), the middle layer (4) and the base layer (5) are stacked in sequence and sent to a laminator, and the layers are firmly bonded to each other through the high temperature and high pressure of the laminator to form an integral waterproof roll material (1);

[0060] According to the overlap requirements, the waterproofing roll (1) is cut into a trapezoidal structure to facilitate the overlap of two adjacent waterproofing rolls (1), thereby reducing the warping and separation at the overlap and improving the waterproofing performance and stability of the overlap; Example 2

[0061] The difference between this embodiment and embodiment 1 is that a light reflection layer is further provided between the absorption layer (2) and the surface layer (3), and the light reflection layer is a metal coating layer or a metal foil film layer; when in use, the light reflection layer has a good reflection effect on ultraviolet rays and infrared rays in sunlight, and when sunlight irradiates the waterproof coiled material (1), after the sunlight passes through the absorption layer (2), it is blocked and reflected by the light reflection layer and cannot continue to irradiate the surface layer (3), the middle layer (4) and the base layer (5), so that the temperature of the waterproof coiled material (1) can be effectively controlled, the temperature difference between the waterproof coiled material (1) and the external environment can be reduced, the shrinkage, deformation and hollowing of the waterproof coiled material (1) can be reduced, and the risk of leakage caused by the occurrence of damaged points in the waterproof coiled material (1) can be reduced;

[0062] The absorption layer (2) is a double-layer structure, which is designed as a sponge layer and a mesh layer from top to bottom. When the waterproof roll (1) contacts rainwater or groundwater, the sponge layer on the absorption layer (2) can quickly absorb a large amount of water, reducing the direct impact of water on the lower waterproof roll (1). At the same time, the water retention of the sponge layer also helps to gradually release water during the drying process, promoting the natural evaporation and air drying of water. The mesh structure of the mesh layer can provide good air permeability, which helps to timely discharge the evaporated moisture in the sponge layer and the circulation of air. At the same time, it can also increase the hanging points of water droplets, reduce the penetration of water droplets into the lower layer, and promote the evaporation of water.

[0063] The surface of the sponge layer is designed with an uneven structure, which can increase the surface area of ​​the sponge layer, help to better absorb and disperse moisture, reduce the direct impact and penetration of moisture on the underlying waterproof membrane (1), and improve the waterproof performance;

[0064] The edge of the adsorption layer (2) is evenly provided with a plurality of air-permeable gaps around the periphery, which can guide air circulation so as to timely discharge moisture during the evaporation of water in the sponge layer, thereby accelerating the evaporation rate of moisture and reducing problems such as aging and cracking of the waterproof roll (1) caused by internal moisture, thereby extending the service life of the waterproof roll (1);

[0065] The heat-resistant particles are designed to be diamond powder or ceramic powder. Diamond powder or ceramic powder has extremely high high temperature resistance. After adding heat-resistant particles to asphalt, the high temperature resistance of the waterproof roll (1) can be improved, making it less likely to soften, flow or deform in a high temperature environment, and the waterproof effect is better;

[0066] An air barrier layer is provided between the surface layer (3) and the middle layer (4); the air barrier layer is made of a polymer coating material; a plurality of exhaust holes are evenly arranged at the bottom of the air barrier layer, which can reduce the intrusion of moisture and gas into the middle layer (4), thereby protecting the asphalt material performance of the middle layer (4) from the influence of moisture and gas, and improving the waterproof stability and reliability of the middle layer (4); the exhaust holes can form tiny air flow channels, promoting the rapid discharge of moisture and gas between the surface layer (3) and the middle layer (4);

[0067] The design of evenly placing glass fibers in the base layer (5) can enhance the tensile strength of the waterproof roll (1). When the waterproof roll (1) is stretched by an external force, the glass fibers can bear part of the tensile force to prevent the waterproof roll (1) from breaking due to excessive stretching. The glass fibers also help to reduce the problems of cracking and falling off caused by the dimensional changes of the waterproof roll (1) under environmental factors such as temperature changes and humidity changes.

[0068] The surface of the base layer (5) is coated with a spray primer, which can penetrate into the tiny pores of the base layer (5) to form a strong mechanical bite force to improve the adhesion between the base layer (5) and the intermediate layer (4). At the same time, the spray primer can make the surface of the base layer (5) more flat and smooth, which is helpful for laying and fixing the waterproof membrane (1); and the lubricating effect of the spray primer helps to reduce bubbles and wrinkles generated in the waterproof membrane (1) during the laying process, thereby improving the waterproof effect.

[0069] The adsorption layer (2) can pre-absorb rainwater or groundwater that it contacts, thereby reducing the penetration of water into other layers and the impact on other layers. By adding wear-resistant and heat-resistant particles to the asphalt of the intermediate layer (4), the high-temperature resistance of the waterproof roll (1) can be improved, making it less likely to soften, flow or deform in a high-temperature environment, thereby achieving a better waterproof effect.
