Abstract

The invention provides a coating sunshade composite material with high reflectivity. The composite material comprises a polyester base material layer, wherein the two side surfaces of the polyester base material layer are coated with a polyvinyl chloride (PVC) thin film layer respectively; a reflecting layer is coated on one side surface of each PVC thin film layer and comprises a PVC base coating layer and a PVC top coating layer; and the aperture rate of the composite material is 2 to 6 percent. The invention also provides a preparation method for the composite material. The composite material has good sunshade and heat-isolation effects.

Description

technical field [0001] The invention relates to a sunshade material, in particular to a coated sunshade composite material with high reflectivity and a preparation method thereof. Background technique [0002] Building energy conservation is a concrete manifestation of the concept of sustainable development, a major trend in world architectural design, and a new growth point of architectural science and technology. The design, construction and use of energy-saving buildings are conducive to the sustainable, rapid and healthy development of the national economy and the protection of the ecological environment. At present, the proportion of my country's building energy consumption to the total social commodity energy consumption continues to increase, which poses a serious threat to my country's social and economic development. For example, the peak load of air conditioners in my country has exceeded 4500kW, which is equivalent to the load capacity of three Three Gorges hydro...
