The project belongs to the application technology field of inorganic non-metallic materials. Building energy conservation is a major measure taken by the country to adhere to sustainable and high-quality development and respond to global climate change. Domestic traditional single or double silver glass can no longer meet the needs of higher-level building energy conservation and building aesthetics. Silver-based coatings have always been recognized as a mainstream energy-saving technology in the industry. The glass processing of high-performance silver-based coatings is extremely complex and is monopolized by foreign countries. The project deeply cultivates new processes and technologies for nano-scale surface modification of glass, overcomes common and key technologies in the domestic industry at that time such as high light to heat ratio (high energy saving), neutral color, light pollution, tempering, and low color difference, and breaks through the bottleneck of industrialization., upgraded and developed five high-performance products based on a market-oriented basis to fill the domestic gap. Low chromatic aberration high-heat ratio three-silver low-emissivity coated glass. The main results of the municipal achievement registration project. The anti-reflection coating layer of a nano-scale composite film coated with a three-layer silver matrix is replaced with a high-refractive-index material, a composite dielectric layer and a composite absorption layer are added, and the film structure and thickness are re-optimized using computer simulation technology. It is close to the high energy-saving effect of light transmission and heat permeability (high light-to-heat ratio). Upgrading and transforming the coating technology and equipment, using ldquo; nonlinear deposition adjustment device rdquo; combined with ldquo; asymmetric gas feeding new process rdquo; control technology, the overall uniformity of the multi-film layer (13 - 16 layers) system with a thickness of about 10 - 20nm is controlled by plusmn;1.5%, improving the color uniformity of glass surface modification, reducing and controlling color differences, and forming stable batch industrial production capabilities. Novelty search is at the same level as international advanced products, with excellent photothermal properties and lower color differences. It can be tempered with three-silver low-emission coated glass. Invention patent authorization, optimize the design of a film system with high hardness and high oxidation resistance, and set the composite structural protective layer and the long path of the composite protective layer to ensure the stability of the triple silver layer and achieve tempering. Neutral color double silver composite structure low-emissivity coated glass. The invention patent authorizes the addition of a copper-aluminum nitride alloy layer to the double silver composite structure to make its transmission color neutral and significantly improve the far-infrared reflectivity. It also improves the structure of the composite dielectric layer of the bottom and middle layers. At the same time, the dense structure of copper nitride can also effectively protect the silver layer. It can be processed in different places and is authorized by utility model. A low-emission coated glass with high light pollution control. Authorized by the invention patent, in the neutral color double silver composite structure, a metal tungsten coating with full spectral absorption is added to the glass base surface, which significantly reduces the reflection (brightness) of indoor and outdoor glass surfaces and suppresses light pollution. Double silver sunshade and low-emission coated glass with ultra-low reflection indoor and outdoor. The utility model patent authorizes that a visible light absorbing layer Cu layer is separately added under the double silver film system to give full play to the characteristics of the Cu layer that is both a low-emissivity plating material and mainly absorbs visible light distributed in the blue and green light region without reflection, making the overall color of the glass more natural, control light pollution and improve sunshade performance. The project has formed a number of independent intellectual property achievements. There are 5 patents authorized, including 3 invention patents and 2 utility model patents. Published 3 papers. The economic benefits of self-transformation of the project are significant. The actual investment in scientific research funding is approximately 10.98 million yuan. From 2016 to 2018, the project sales revenue is 168.4 million yuan, taxes are 4.65 million yuan, and net profit is 8.92 million yuan. High-performance products are promoted and applied to landmark buildings and large-scale projects such as Shanghai Center, Pudong International Airport Phase III, and Shanghai International Financial Center. The social benefits of the project are obvious. Alternative imports provide cheap and localized high-end product support for domestic high-level building energy conservation, upgrade domestic related industries into the international advanced ranks, and change the backward image that has always been in the mid-to-low-end manufacturing industry chain. The project sub-topic was approved by the local plan (Shanghai City). The project sub-project won the second prize and first prize of the National Building Materials Industry Technological Innovation Award in 2016 and 2018.
