In order to meet the country's increasingly strict requirements for building energy efficiency, China's leading glass fiber composite material manufacturer CQGJ Composite Material Technology Group and Covestro, and machinery manufacturer KraussMaffei have signed a memorandum of cooperation to cooperate in development based on Coves Chuang Baiduo® polyurethane pultruded composite energy-saving window solution, leading the energy-saving upgrade of door and window profiles.
Julien Guiu, Vice President, Marketing, Asia Pacific, Covestro Polyurethanes Business Unit, said: "Covestro has more than 80 years of innovation history. As the inventor of polyurethane, we applied polyurethane pultruded composite materials to door and window systems. Energy-saving breakthrough in system doors and windows."
Material innovation makes doors and windows more energy efficient
Baiduo® glass fiber reinforced polyurethane energy-saving window uses alkali-free glass fiber as the reinforcing material, polyurethane resin as the matrix resin, and is made of profiles formed by the closed-mold injection pultrusion process. It integrates thermal insulation, energy saving, fire safety, sound insulation and noise reduction. In one. The traditional broken bridge aluminum door and window system uses glass fiber reinforced nylon PA66+GF25 as the heat insulation material. With the increasing requirements for heat insulation and energy saving, the width of the heat insulation strip is increasing, the profile structure is more and more complicated, and the cost is rising.
The Bayo® glass fiber reinforced polyurethane pultruded composite material profile widens the insulation distance, has a low heat transfer coefficient and good insulation performance. In the specific design, the K value of the system doors and windows can be as low as 0.77 w/m2•k. In addition, by simplifying the cross-sectional structure of the profile, the overall cost of the system doors and windows can be reduced. The excellent sound insulation of the profile also reduces indoor noise. At the same time, the system window has passed the national standard one hour fire integrity test.
Tripartite alliance to lead the future building door and window market
According to the three-party cooperation memorandum signed this time, Covestro will deepen the research and development of innovative technologies of Baiduo® glass fiber reinforced polyurethane energy-saving windows to meet the higher energy-saving requirements of future buildings.
As one of the leading companies in the glass fiber industry, CQGJ will further research and develop glass fibers for high-speed polyurethane pultrusion process, and rely on the advantages of its glass varieties and interface treatment agents to meet customer requirements for efficiency, surface quality and strength. Yao Yuan, deputy general manager of CQGJ, said: "The use of composite materials for energy-saving doors and windows is a general trend. The closed profile injection pultrusion polyurethane profile has environmentally friendly production processes, high fiber content, high modulus, high strength and close expansion coefficient. The advantages of concrete and strong nail-holding strength. The development of the Chaoyang industry requires the integration of many aspects of technology. The strong cooperation of the three parties in this cooperation will give play to their respective advantages and provide customers with reinforcement materials, matrix resins and molding equipment. The systematic solution is committed to promoting the development of the energy-saving door and window industry."
As a leading equipment supplier in Germany, KraussMaffei specializes in the development of high-efficiency special equipment for pultrusion of polyurethane, which helps the polyurethane profile production enterprises achieve industrialization and scale. "In recent years, KraussMaffei and its partners have actively explored the development of closed-mold injection-type rapid reaction pultrusion systems to provide the industry with a more efficient, intelligent, environmentally friendly and integrated production method. For the production of new door and window profiles While providing technical solutions, it has also achieved new energy-saving doors and windows with low heat transfer coefficient, easy coating, high strength and high flame retardancy." Xu Yutang, Vice President of Reaction Molding Division of Shanghai KraussMaffei Machinery Co., Ltd. Expressed expectations for this tripartite cooperation.
This time, Covestro, CQGJ and KraussMaffei have joined forces to sign a memorandum of cooperation to coordinate the advantages of the three parties and inject new kinetic energy into the promotion of Baidu® glass fiber reinforced polyurethane pultrusion composite energy-saving windows. By jointly supporting the development of the national green building market in the form of a dot-and-face approach, it aims to provide Chinese residents with a better stay experience, promote the upgrading of the local construction industry, and explore sustainable development solutions for future buildings.
