specific Embodiment approach 1

[0015] Embodiment 1: A method for preparing a color-changing intelligent low-emissivity glass is specifically carried out in accordance with the following steps:

[0016] 1. Cleaning of the base ITO glass: select ITO glass as the base layer, use methanol, acetone and ultrapure water to clean the ITO glass in sequence, and then dry it with nitrogen to obtain a clean ITO glass;

[0017] 2. Preparation of electrolyte layer film: ①. Dissolve polyvinyl butyral powder in N,N-dimethylformamide to obtain polyvinyl butyral / N,N-dimethylformamide solution, and then Add potassium nitrate, lithium chloride, citric acid and polyvinylpyrrolidone, heat at a temperature of 60°C to 80°C for 30min to 60min to obtain a mixed solution, and coat the mixed solution evenly on the surface of the polytetrafluoroethylene substrate. Cool at -10°C to form a gel-like film, which is separated from the polytetrafluoroethylene substrate to obtain a gel-like film; the mass ratio of the polyvinyl butyral powder...

specific Embodiment approach 2

[0020] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that in step 1, methanol, acetone and ultrapure water are used to perform ultrasonic cleaning on ITO glass. 40min, then use acetone for ultrasonic cleaning, ultrasonic cleaning for 20min to 40min, and finally use ultrapure water for ultrasonic cleaning, ultrasonic cleaning for 20min to 40min. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0021] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is: the quality of polyvinyl butyral powder described in step 2 1. and the volume ratio of N,N-dimethylformamide is 1g:5mL. Others are the same as those in the first or second embodiment.

Abstract

The invention relates to a color-changeable intelligent low-emissivity glass preparation method and aims at solving the problems that emissivity of existing Low-E glass cannot be adjusted at will and color control cannot be achieved. The method comprises the steps: 1, cleaning substrate ITO glass; 2, preparing an electrolyte layer film; 3, packaging glass. According to the color-changeable intelligent low-emissivity glass preparation method disclosed by the invention, a metal membrane layer of the low-E glass is utilized, optical performance of visible and infrared bands of the glass is controlled by controlling particle size, density and morphology of surface particles on the surface of the metal membrane layer, and the novel color-changeable intelligent low-emissivity glass can be developed; namely, transmittance of the visible band and reflectivity and emissivity of the infrared band of the glass can be adjusted according to a self requirement to meet requirements under different weather conditions; meanwhile, color of the glass can be adjusted at will, and an individual requirement of people can be met. The color-changeable intelligent low-emissivity glass preparation method disclosed by the invention can be applied to preparing the color-changeable intelligent low-emissivity glass.

Description

technical field [0001] The invention relates to a preparation method of color-changing intelligent low-emissivity glass. Background technique [0002] Low-emissivity glass, also known as low-E glass, uses physical or chemical methods to coat a metal film or metal oxide film containing one or two or even multi-layer films on the glass surface to reduce energy absorption or control Indoor and outdoor energy exchange ensures the comfort of life and work, and achieves the purpose of environmental protection and energy saving. Low-E glass can be divided into high transmission type and low transmission type. The high-transmittance type has higher solar transmittance and visible light transmittance. During the day, sunlight can penetrate the glass to the maximum extent and enter the room to ensure sufficient solar radiation indoors. It is suitable for northern cold regions; High transmittance, but low transmittance to ultraviolet and near-infrared, high reflectivity in the mid-to...
