Problems solved by technology

However, the precursors used to prepare TiN thin films by chemical methods are mostly titanium amide complexes, which are easily hydrolyzed and oxidized in air and moisture. During the preparation and heat treatment of thin films, the reaction environment requires low oxygen content, and some require NH 3 Atmosphere or N 2 Atmosphere, harsh experimental conditions and certain dangers, not suitable for large-scale coating production

Embodiment Construction

[0023] The present invention will be described in detail below in conjunction with embodiments and drawings, but the present invention is not limited to this.

[0024] Such as figure 1 with figure 2 As shown, the steps for preparing TiN coated glass in this embodiment are as follows:

[0025] (1) Ultrasonic cleaning the quartz plate (glass substrate) with surfactant, ethanol, and water for 30 minutes, and vacuum drying at 80°C;

[0026] (2) Dissolve 309.4 mg of TiN powder in 100 mL of ethanol aqueous solution with a volume ratio of 1:1, and configure it to a concentration of 0.05 mol·L -1 Use an ultrasonic pulverizer to treat the suspension for 30 minutes to obtain a uniformly dispersed TiN precursor;

[0027] (3) Open the heating platform 5, place the cleaned quartz plate (namely the glass substrate 4) on the platform, raise the temperature to 240°C, measure the temperature of the substrate with a temperature gun, and control the temperature change within the range of ±5°C;

Abstract

The invention discloses a preparation method for TiN film coated glass. The preparation method comprises the following steps: dissolving TiN nanometer powder in a volatile organic solvent so as to prepare a film-coating precursor suspension, and carrying out ultrasonic treatment so as to obtain a uniformly-dispersed TiN film coating precursor with a concentration of 0.01 to 0.1 mol.L / 1; cleaning aglass substrate, and carrying out heating; and atomizing the TiN film coating precursor by utilizing ultrasound, spraying the atomized TiN film coating precursor onto the surface of the glass substrate, and carrying out deposition so as to obtain glass coated with a TiN film. According to the invention, by adopting the TiN nanometer powder as a raw material and utilizing the characteristics of solvent volatility and assistant atomization of solid nanoparticles with the ultrasound, and in virtue of characteristics like high surface energy and large specific surface area of nanoparticles, the preparation method realizes deposition of a TiN nanostructured film under the conditions of normal pressure and low temperature.

Description

Technical field [0001] The invention belongs to the field of energy-saving coated glass, and particularly relates to a method for preparing TiN coated glass by adopting an ultrasonic atomization method and nano TiN powder. Background technique [0002] Entering the 21st century, countries around the world have rapidly developed science and technology, and their overall national strength has been significantly improved. However, along with natural problems such as shortage of natural resources and environmental pollution, the living environment of mankind has encountered unprecedented challenges. my country is also a big energy consuming country, and the energy consumption of buildings accounts for nearly 40% of the total energy consumption of the whole society, and it is showing an upward trend year by year. Building energy consumption in a narrow sense mainly refers to the operating energy consumption of the building, that is, daily energy consumption, including heating, air con...
