Problems solved by technology

At present, the research on functional materials is mainly focused on a single function, which is far from meeting people's needs. The demand for multifunctional materials has become more and more obvious, and it is also an inevitable trend of social development.
Insulation treatment of some outdoor transparent substrates such as building doors and windows, vehicle windows, lighting fixtures, telephone booths, newsstands, etc. can save a lot of energy loss. If it has a self-cleaning function on this basis, it can also save more energy. More manpower and material resources, improve work efficiency, especially when cleaning high-rise buildings consumes a lot of time and resources, and high-altitude operations are unsafe

Abstract

The invention relates to a method for preparing a multifunctional composite nanophase material, which belongs to the technical field of functional materials. The method prepares the multifunctional composite nanophase material by composition of nanophase materials with transparent and heat-insulation functions and nanophase materials with self-cleaning and antifouling functions in proportion. The material has multiple functions of transparency, heat insulation, self-cleaning, antifouling, antibacterium and electrostatic prevention, and can be used for preparing a multifunctional additive or a functional plastic master batch in coating. The multifunctional composite nanophase material accords with the demand and the direction of the modern social development, and has wide development prospect on transparent substrates such as windows and doors of buildings, windows and doors of vehicles, transparent light fittings, telephone booths and newsstands.

Description

technical field [0001] The invention discloses a method for preparing a multifunctional nanocomposite material, relating to a method for preparing a multifunctional additive that can be used in coatings or a functional masterbatch for plastics, and belongs to the technical field of functional materials. Background technique [0002] With the development of science and technology and the improvement of living standards, people have higher and higher requirements for the functionality of materials, which not only need to be economical and energy-saving, but also improve the quality of life. At present, the research on functional materials is mainly focused on a single function, which is far from meeting people's needs. The demand for multifunctional materials has become more and more obvious, and it is also an inevitable trend of social development. Insulation treatment of some outdoor transparent substrates such as building doors and windows, vehicle windows, lighting fixture...
