Abstract
Description
Technical Field
[0001] This invention relates to the field of building wall panel technology, specifically to the production process of ultra-high performance exterior wall panels. Background Technology
[0002] The primary application of building exterior wall panels is their application on building exterior walls. They possess a dual core function: superior thermal insulation performance and diverse decorative effects. Due to their excellent adaptability, they are widely used in a wide range of construction fields. Whether it's a new building requiring high standards in both exterior wall insulation and decoration, or an older building urgently needing energy-saving renovation and exterior refurbishment, integrated insulation and decoration panels can perfectly meet these needs. In terms of building type, their application scope covers various public buildings and is deeply integrated into the exterior wall insulation systems of residential buildings, providing residents with a comfortable living environment while enhancing the overall aesthetics of the building. Furthermore, whether in the frigid north where the need to withstand harsh winters and ensure indoor warmth, or in the hot south where effective heat insulation and cooling are needed to maintain indoor coolness, integrated insulation and decoration panels can reliably perform their function thanks to their excellent performance. Their superior quality in terms of thermal insulation performance, fire resistance, durability, and decorative effects makes them stand out in the field of building insulation and decoration technology, becoming the undisputed first choice for insulation and decoration materials in the industry.
[0003] Currently, common thermal insulation decorative panels on the market, such as calcium silicate board insulation panels, stone insulation panels, ceramic insulation panels, and sintered ceramic integrated insulation panels, all use decorative panels (decorative layers). When applied to building exterior wall insulation, there are many technical problems that urgently need to be solved:
[0004] Firstly, the substrate of calcium silicate board insulation panels has a high water absorption rate, making them prone to deformation and exhibiting poor weather resistance. While the surface is decorated through a painting process, the organic paint is susceptible to fading and discoloration over time, and is not stain-resistant, making it difficult to maintain its aesthetic appeal in the long term.
[0005] Furthermore, ultra-thin integrated stone insulation panels suffer from high breakage rates during production due to the significant color variations and high density of natural stone, resulting in relatively high costs. Additionally, the supply stability is challenged by limitations in stone mining resources.
[0006] Secondly, the sintered ceramic integral molding insulation board is formed in one piece using a sintering process, which results in huge production energy consumption and causes certain environmental pollution. Moreover, the product is generally brittle and has poor impact resistance, posing safety hazards in actual use. Summary of the Invention
