Abstract

The invention specifically relates to an electrochromic laminated glass and a preparation method thereof, belonging to the technical field of energy-saving glass. According to the invention, a solid gel electrolyte is used as an ion transport layer so as to successfully overcome the problems of great inconvenience in packaging and unsuitability for large-area display of conventional electrochromic laminated glass using a liquid electrolyte. Through adjustment of composition and proportion of the solid gel electrolyte, the eventually formed ion transport layer has good ion transport performance. Moreover, the electrochromic laminated glass uses a PC film or a PMMA film as a substrate and cooperatively uses a thermal insulation glue film to highly efficiently shield infrared rays and ultraviolet rays; thus, the prepared electrochromic laminated glass has a heat reflection function, guarantees high-efficiency selectivity to spectra, can automatically carry out color regulation and control, light adjustment and temperature adjustment, has the characteristics of high efficiency, low energy consumption, greenness, environmental protection, intelligentialization, substantially reduces energy load of a building, and accords with the current development requirements for energy conservation, emission reduction and low-carbon economy.

Description

technical field [0001] The invention relates to the technical field of energy-saving glass, in particular to an electrochromic laminated glass and a preparation method thereof. Background technique [0002] With the development of national economy and modern science and technology, people pay more and more attention to energy saving and environmental protection. In the ever-increasing total energy consumption of society, building energy consumption occupies a large proportion. my country's building energy consumption has accounted for 27.6% of the total energy consumption of the whole society, and it is increasing year by year. Therefore, building energy conservation has become a long-term strategic policy of my country's economic development. Laminated safety glass is widely used in the construction industry due to its excellent properties such as safety, sound insulation, heat insulation, and UV resistance. Its excellent heat insulation performance is mainly due to the t...
