Problems solved by technology

For example: when the indoor heating is turned on in winter, due to the poor insulation ability of the windows, a large amount of indoor heat will be neutralized by the low temperature outside through the heat conduction of the windows, resulting in a large amount of energy loss; similarly, when the air conditioner is turned on in summer, There is also the same problem, causing a lot of energy loss
At the same time, the lighting facilities of various decorative and advertising landscapes in the city at night also cause increasingly serious light pollution, endangering the life, rest and health of urban residents
However, it is impossible for a building to have no windows. Therefore, how to block the heat exchange inside and outside the window and the harmful light source that enters the room from the outside poses new challenges to the field of new materials for curtains and window decorations.

Abstract

The invention discloses a preparation method of a shading composite material, which includes the following steps: (1) performing vacuum aluminum-plating processing treatment to a non-corona surface of a first transparent thin film layer to obtain a first vacuum aluminum-plated layer of which the thickness is 400-700 angstrom; (2) laminating a non-corona surface of a second transparent thin film layer with the first vacuum aluminum-plated layer in the step (1) through a composite adhesive to obtain a double-layer composite material; and (3) laminating a corona surface of the second transparent thin film layer in the double-layer composite material in the step (2) with a nonwoven cloth in a manner of polyethylene coating film lamination. The shading composite material prepared through the method has the protective functions of resisting ultraviolet and infrared ray and the like, and meanwhile, the preparation can be carried out through the processing technologies in the prior art, so that the method is excellent in popularization and application value.

Description

technical field [0001] The invention relates to a preparation method of a light-shielding composite material. Background technique [0002] At present, the mainstream thinking in the world is environmental protection, energy saving and safety. In the construction industry, the manufacture and application of windows in today's buildings will bring a lot of energy consumption and light pollution. For example: when the indoor heating is turned on in winter, due to the poor insulation ability of the windows, a large amount of indoor heat will be neutralized by the low temperature outside through the heat conduction of the windows, resulting in a large amount of energy loss; similarly, when the air conditioner is turned on in summer, There is also the same problem, causing a lot of energy loss. At the same time, the lighting facilities of various decorative and advertising landscapes in the city at night also cause increasingly serious light pollution, endangering the life, res...
