Abstract

The invention discloses a preparation method of heat-insulating tempered glass. The preparation method comprises the following steps: firstly, pretreating the surface of glass; secondly, putting fused salt into a strengthening furnace salt bath, and heating to melt the fused salt into liquid to obtain fused salt liquid; thirdly, soaking the glass into the fused salt liquid and carrying out ion exchange treatment; fourthly, feeding the glass into a tempering furnace and carrying out heat treatment; and fifthly, putting the glass into a weak acid solution for soaking, cleaning and drying; then spraying a heat insulating material on the surface of the glass, roasting and cooling to obtain the heat-insulating tempered glass. According to the preparation method disclosed by the invention, raw materials used for the production process and mixture ratio are optimized, and production process parameters are strictly controlled, so the prepared heat-insulating tempered glass has the advantages of good heat insulating effect, excellent fireproof effect, excellent performance and suitability for being used on multiple occasions.

Description

technical field [0001] The invention belongs to the technical field of toughened glass, and in particular relates to a preparation method of heat-insulating toughened glass. Background technique [0002] As one of the most commonly used forms of safety glass, tempered glass is 4-5 times stronger than ordinary glass, 3-5 times more resistant to bending, and 5-10 times more impact-resistant than ordinary glass. In addition, tempered glass is broken into small fragments without sharp angles. Its resistance to rapid cooling and thermal properties is 2 to 3 times higher than that of ordinary glass, and it can generally withstand temperature changes above 150°C. Indispensable in the field of automotive technology. According to different production processes, tempered glass is divided into physical tempered glass and chemical tempered glass. The surface of the tempered glass forms uniform compressive stress, while the interior forms tensile stress, which improves the bending and ...
