Polyurethane material for building door and window profile, building door and window profile and preparation method of building door and window profile

In 2010, the British zero carbon hall of Shanghai world exposition and the German hamburger family are the first exploration of buildings in China toward lower energy consumption. In 2012, under the support of the ministry of China housing and urban and rural construction and the German Federal department of transportation, construction and urban development, the scientific and technological development promotion center of the ministry of housing urban and rural construction and the German energy agency introduce the German construction energy-saving technology, and the demonstration projects of the Hebei Qin Huang island on the water side, the Heilongjiang Harbin xi tree courtyard and the like are built. In 2013, the building energy-saving working group of the Chinese and American clean energy combined research center develops research and cooperation in the technical fields of near-zero energy consumption buildings and zero energy consumption building energy conservation, completes demonstration projects of the near-zero energy consumption buildings and the like of the Chinese building science research institute, and obtains very good energy-saving effect and wide social influence.
The building department and all places release the relevant technical standard of 'near zero energy consumption building', and put forward high requirements for the heat transfer coefficient of doors and windows. If the local standard of Beijing, namely the residential building energy-saving design standard, is to be implemented, the whole window heat transfer coefficient is required to be upgraded to 1.1, and most of doors and windows in the current market are eliminated.
However, the existing common 'strip-penetrating' and 'glue-injection' bridge-cut-off aluminum profiles have small sections, limit further reduction of heat transfer coefficients of door and window frames, and have poor energy-saving effect. The polyurethane structural foam is an organic polymer material with the characteristics of high strength, tear resistance, wear resistance and the like, has good waterproof and moisture-proof properties and good heat insulation properties, has a heat conductivity coefficient of 0.051W/m.k, has a stable closed-cell structure of polyurethane, is resistant to freezing and thawing, has good sound absorption performance, has a long service life which can be more than 30 years, and is resistant to acid, alkali and electrochemical corrosion.
