Description

Technical Field

[0001] The present invention discloses a multi-dimensional stretching detection device and method for heat-stable high-performance waterproof coiled materials, which relate to a detection device and a detection method for detecting the tensile properties of heat-stable high-performance waterproof coiled materials, belonging to the technical field of waterproof materials, and particularly to a detection device and a detection method which can stretch the waterproof coiled material in a vertical direction by a second telescopic rod, and stretch the waterproof coiled material in multiple different horizontal directions by a third telescopic rod, and can perform multi-directional overall tensile performance detection on different parts of the waterproof coiled material and the overlap of two adjacent waterproof coiled materials, thereby improving the detection accuracy. 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.

[0003] Publication No. CN114670502A discloses a waterproof roll material, including a polyester fiber non-woven fabric, a jute cloth covering the polyester fiber non-woven fabric, a glass fiber felt covering the jute cloth, an anti-corrosion protective layer covering the glass fiber felt, a filling layer covering the anti-corrosion protective layer, and a waterproof layer covering the filling layer. However, the waterproof layer of the waterproof roll material cannot pre-absorb or treat rainwater or groundwater that it contacts, and the retention of water on the surface of the waterproof layer is likely to cause erosion and damage to it, and the possibility of water seepage is relatively high; the filling layer of the waterproof roll material is modified 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 overlapping method of the waterproof roll material is generally single-sided welding, and the overlapping area is prone to warping and separation, resulting in gaps between the roll materials or between the roll materials and the base layer, which cannot effectively prevent water penetration, resulting in water seepage and leakage, and poor waterproof performance.

[0004] In order to improve the above problems, the applicant filed a Chinese invention patent application entitled "A heat-stable high-performance waterproofing membrane and its preparation method". Before using the above heat-stable high-performance waterproofing membrane, it is necessary to test the tensile properties of the waterproofing membrane to understand the tensile resistance of the waterproofing membrane under stress and ensure that the waterproofing membrane can maintain a stable waterproof effect during use. At present, the tensile properties of the waterproofing membrane are mainly tested by a tensile testing machine. The specific steps are: first, cut a sample of a certain length and width from the waterproofing membrane, then install the sample between the two clamping mechanisms of the tensile testing machine, and then start the tensile testing machine to start stretching the waterproofing membrane. During the stretching process, the tensile testing machine will record and display the load, displacement and other data in real time; finally, when the sample is broken, the maximum force during the test, the elongation value at the maximum tension and other data are recorded, and processed and analyzed to evaluate whether the tensile properties of the waterproofing membrane meet the standard requirements. However, the tensile testing machine only tests waterproof membranes of a certain length and width, and does not perform an overall tensile test on multiple overlapping waterproof membranes. It is necessary to perform multiple tests on samples at different locations to fully reflect the tensile properties of the entire roll or large-area waterproof membrane, which is time-consuming and labor-intensive. It is also unable to test the tensile properties of the overlaps of two adjacent waterproof membranes, which may easily lead to water seepage problems at the overlaps due to weak tensile properties during actual use. At the same time, it only performs tensile tests on the samples in the up and down directions, and the tensile direction is single, which cannot fully simulate the stress conditions of the waterproof membrane that may be subjected to shear and tear forces in multiple directions during actual use, and the detection accuracy is low.

[0108] 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;

[0109] 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.

[0110] 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 lower waterproof membrane (1), and improve the waterproof performance;

[0111] 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 the water and reducing the aging and cracking of the waterproof roll (1) caused by internal moisture, thereby extending the service life of the waterproof roll (1);

[0112] 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;

[0113] 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);

[0114] 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.

[0115] 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.

[0116] 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.

[0117] It should be noted that, unless otherwise clearly specified and limited, the terms "placed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection method such as a folding connection, a rivet connection, a pin connection, a bonding connection and a welding connection, or a detachable connection method such as a threaded connection, a snap connection and a hinge connection, or an integral connection, or an electrical connection, or a direct connection, or an indirect connection through an intermediate medium, or the internal connection of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0118] It should be further pointed out that, when describing the above specific embodiment, for the sake of simplicity and clarity, only the differences between the above specific embodiment and other embodiments are described, but those skilled in the art should know that the above specific embodiment itself is also an independent technical solution.
