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 shading composite material, which includes, in a laminated manner, a first transparent thin film layer, a first vacuum aluminum-plated layer, a composite adhesive layer, a second transparent thin film layer, a polyethylene coating film layer and a nonwoven cloth layer. The thickness of the first vacuum aluminum-plated layer is 400-700 angstrom. A second vacuum aluminum-plated layer is clamped between the composite adhesive layer and the second transparent thin film layer and is 400-700 angstrom in thickness. The shading composite material has the protective functions of resisting ultraviolet and infrared ray and stopping visible light and the like, and is excellent in popularization and application value.

Description

technical field [0001] The invention relates to 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, rest and health of urban re...
