Description

Technical Field

[0001] This utility model relates to the field of waterproof membranes, specifically to a waterproof membrane with good high-temperature resistance. Background Technology

[0002] Waterproof membrane is a roll-shaped material used in waterproofing projects. It is mainly used to prevent water penetration. By selecting the appropriate waterproof membrane based on specific environmental conditions, construction requirements, and economic budget, and by carrying out professional construction and maintenance, water penetration can be effectively prevented and the long-term stability of buildings and structures can be protected.

[0003] Chinese Patent CN213612443U discloses a waterproof membrane with good high-temperature resistance. The membrane includes a waterproof membrane body, which comprises a base layer, a heat-resistant layer, and an anti-corrosion layer. The base layer is located at the bottom of the heat-resistant layer and at the top of the anti-corrosion layer. The heat-resistant layer includes a polyvinyl fluoride coating layer, a water-based inorganic zinc-rich coating layer, and a fluorocarbon coating layer. The polyvinyl fluoride coating layer is located on top of the water-based inorganic zinc-rich coating layer and is connected by a water-based laminating adhesive. This invention achieves excellent high-temperature resistance through the combined use of the waterproof membrane body, base layer, heat-resistant layer, polyvinyl fluoride coating layer, water-based inorganic zinc-rich coating layer, fluorocarbon coating layer, anti-corrosion layer, aluminum tripolyphosphate coating layer, and polypropylene coating layer. It solves the problem that existing waterproof membranes often have poor high-temperature resistance, easily deforming after heating, thus affecting their service life and making them inconvenient to use.

[0004] However, the aforementioned disclosed technical solutions have the following shortcomings: the direct connection between the waterproof membrane base layer, heat-resistant layer, and anti-corrosion layer may lead to interlayer delamination or cracking due to thermal expansion stress caused by temperature changes and mechanical stress, and the overall structural durability and impact resistance need to be improved. Furthermore, the protective capability of the waterproof membrane surface needs to be enhanced. Utility Model Content

[0005] The purpose of this invention is to address the problems in the background technology, such as the potential for interlayer delamination or cracking, and the need to improve surface protection, by proposing a waterproof membrane with good high-temperature resistance.

[0006] The technical solution of this utility model is: a waterproof membrane with good high temperature resistance, comprising a waterproof membrane body, wherein the waterproof membrane body is provided with an outer protective layer, a coating layer, a heat-resistant layer and a connecting layer from the outside to the inside, a buffer layer is provided between the coating layer and the heat-resistant layer, and a buffer layer is provided between the heat-resistant layer and the connecting layer.

[0007] The outer protective layer enhances the surface's resistance to scratches, corrosion, and ultraviolet radiation; the buffer layer absorbs thermal expansion stress caused by temperature changes and mechanical stress, preventing delamination or cracking between layers; and the connecting layer connects to the mounting surface.

[0008] Preferably, the heat-resistant layer is the substrate, and the heat-resistant layer is an inorganic silicate coating with a thickness of 0.15-0.4 mm.

[0009] Preferably, the buffer layer is an elastomer or a low-modulus material with a thickness of 0.1-0.3 mm, and is uniformly coated on both sides of the heat-resistant layer by roller coating or spray coating process.

[0010] Preferably, the coating layer is a polyvinylidene fluoride coating layer with a thickness of 0.2-0.5 mm, and the polyvinylidene fluoride coating is uniformly applied to the buffer layer above the heat-resistant layer by spraying or roller coating.

[0011] Preferably, the outer protective layer is a nano-ceramic protective coating with a thickness of 0.05-0.1 mm. The outer protective layer is formed on the surface of the coating layer by plasma spraying or chemical vapor deposition.

[0012] Preferably, the connecting layer is the innermost layer and is connected to the mounting plane. The connecting layer is a fluorocarbon coating layer, such as polytetrafluoroethylene (PTFE), with a thickness of 0.2-0.6 mm. The fluorocarbon coating is uniformly applied to the bottom of the buffer layer below the heat-resistant layer by thermal spraying or roller coating processes.

[0013] Compared with existing technologies, the above-mentioned technical solution of this utility model has the following beneficial technical effects: By adding anti-aging additives to each layer, adding a nano-ceramic protective coating on the outermost layer, and adding a buffer layer between the coating layer, heat-resistant layer, and connecting layer, the improved structure significantly enhances the material's anti-aging ability, durability, and stress cracking resistance. Interlayer bonding is mainly achieved through the coating process; the adhesion of the material itself and the tightness of the coating process ensure the bonding strength between layers. This improved structure is suitable for complex environments such as high temperature, high humidity, and strong corrosion, effectively extending the material's service life and improving its waterproof effect.
