建筑节能膜制备技术进展

Progress of the Building Energy-Saving Membrane Preparation Technology

随着经济的快速发展、城市化进程的加快,我国的建筑能耗增长迅速,其中,门窗与外界热交换导致的能量损耗约占建筑能耗的50%,粘贴建筑节能膜,实行节能窗技术势在必行。文章介绍了建筑节能膜的应用和种类,详细介绍了3种建筑节能膜最新制备技术:高透明纳米树脂复合技术、VO2节能窗技术和微纳多层膜复合技术的原理及其优缺点,重点介绍了一种新型的制备微纳多层光学膜制备技术。与现有技术相比,新型微纳多层光学膜制备过程流道规整性更好,流动阻力更低,可实现不同折射率多层梯度膜的均匀复合,同时该技术工艺流程简单,生产成本低,精度容易保证,能够有效提高物料的适应性和制造的效率,具有非常广泛的应用价值。

With the economic development and urbanization process speeding up, building energy consumption is growing rapidly in our country, energy loss caused by heat exchanging through doors and windows is about 50 percent of building energy consumption, so that it is imperative to paste the building energy-saving membrane and implement energy-saving window technology, the application and species of building energy-saving membrane, and the latest preparation technology in detail are introduced： the high transparent nano-resin composite technology, the VO2 energy-saving window technology and the micronano multilayer fihn composite technology. Meanwhile, a new kind of micronano laminated technology is focused on the micronano laminated technology can achieve muhiplayer uniform composition of different refractive index fihns in gradient. Compared with the current technologies, during the preparation process, it has better flow path, lower flow resistance, meanwhile, the production cost is low, the accuracy is easy to guarantee, and the adaptability and the manufacturing efficiency of the materials are greatly improved, so that the technology has better application prospect.
