A kind of multi-layer composite film door and window glass with double function and preparation method thereof

Abstract

The invention relates to dual-functioned multi-layered composite thin film door and window glass and a preparation method thereof. The problems that the number of film layers is large, function is less, preparation process is tedious, and the cost is high in the prior art are effectively solved. According to the g technical scheme, the dual-functioned multi-layered composite thin film door and window glass comprises substrate glass, a low-radiation functional thin film layer and a self-cleaning functional thin film layer, a titanium nitride layer, a silver layer, a cuprous oxide layer, and a titanium dioxide layer sequentially cover the substrate glass, the titanium nitride layer and the silver layer constitute the low-radiation functional thin film layer, and the cuprous oxide layer and the titanium dioxide layer constitute the self-cleaning functional thin film layer. The dual-functioned multi-layered composite thin film door and window glass has a low-radiation function, a self-cleaning function, at the same time, comparatively high reflectivity in an ultraviolet region and a near infrared region, and certain transmittivity in a visible light region; and the dual-functioned multi-layered composite thin film door and window glass is prepared by using a magnetron sputtering method, the dual-functioned multi-layered composite thin film door and window glass and the preparationmethod thereof are a novelty in the multi-layered composite thin film door and window glass.

Description

technical field [0001] The invention relates to a functional film material and a preparation method thereof, in particular to a double-functional multilayer composite film door and window glass and a preparation method thereof. Background technique [0002] Energy conservation and environmental protection are the development theme of the present era. The current energy development methods mainly include solar energy, bioenergy and nuclear energy, among which solar energy is the safest, environmentally friendly and cheap energy method. [0003] According to statistics, my country's building energy consumption accounts for about one-third of the total energy consumption. Except for the energy consumed by building materials, most of the energy is consumed in heating and cooling, and nearly half of it is passed through buildings. What is lost by doors and windows. To deal with this energy waste, an effective and feasible way is to gradually replace traditional materials with nan...
