Abstract

The invention belongs to the technical field of optical coating, and particularly relates to a solar control-low radiation type heat-insulation membrane system, which aims to provide the solar control-low radiation type heat-insulation membrane system capable of functioning in reflecting near infrared rays, middle infrared rays and far infrared rays. The membrane system comprises a PET layer (1), TiO2 layers (2), an Ag layer (3) and a Ti layer (4), wherein the PET layer (1) is a substrate; the first TiO2 layer (2) is covered on the PET layer; the Ag layer (3) is covered on the TiO2 layer (2); the Ti layer (4) is covered on the Ag layer (3); and the second TiO2 layer (2) is covered on the Ti layer (4). The solar control-low radiation type heat-insulation membrane type has low radiance, proper shading coefficient, the functions of sunshade and heat preservation and wide application, can function in reflecting the near, middle and far infrared rays and reduce the inflow and outflow of indoor heat, and is applied in summer, winter and hot and cold regions.

Description

technical field [0001] The invention belongs to the technical field of optical coating, and in particular relates to a solar control-low radiation type heat-insulating film system. Background technique [0002] The performance of thermal insulation film products is generally divided into sunshade type and LOW-E type, and the two types of thermal insulation film systems are usually different. Specifically, the function of the sun-shading heat-insulating film is to block the near-infrared energy in sunlight. It is mainly used in hot climate areas, and its film structure mostly uses electronegative element single metal or metal oxide (such as chromium, titanium, stainless steel, etc. ); LOW-E thermal insulation film is to block the transmission of mid- and far-infrared rays. The LOW-E type is mainly used in cold climate areas, and the film structure mostly uses electropositive metal elements, precious metals or metal oxides (such as silver, gold, copper, etc.). Generally, the...
