Description

technical field [0001] The invention relates to the field of auto parts, in particular to a process for preparing heat-insulating glass for automobiles. [0002] Background technique [0003] Insulating glass was discovered by Zimandy when studying the absorption spectrum of iron-containing ions. Ionic glass absorbs almost all infrared light, while Ions are developed on the basis of significant absorption of visible light. Silicate insulating glass was first systematically studied, but the glass is dark blue, so it also has considerable absorption of visible light. The application number is CN 201010107383.4 Disclosed is a conductive heat-insulating glass and a manufacturing method thereof. The manufacturing method of the glass includes the following steps: (1) Purifying the glass: first washing the dirt on the glass with 45°C-55°C hot water, and then using the purified ion Wash with pure water and dry; (2) heat the purified glass to 460°C-600°C, then use a high-pressur...
