Problems solved by technology

[0004] However, after two pieces of tempered glass are combined, their thickness increases greatly. In the case where tempered glass with a smaller thickness is required, the tempered glass produced by the above method is obviously not suitable for use, and its applicability is low.

preparation example 1

[0059] Preparation of silica airgel powder:

[0060] Add 20g of tetraethyl orthosilicate, 80g of ethanol and 30g of water into the reaction flask and mix to form a mixed solution. Stir and disperse with a mechanical stirrer for 20 minutes. The stirring temperature is 50°C. Add 1mol / L hydrochloric acid to adjust the pH of the mixed solution to 3. Continue Stir for 3 hours, add 1mol / L ammonia water to adjust the pH of the mixture to 7, continue to stir for 2 minutes, naturally cool to room temperature, and let it stand for 1.5 hours to obtain a silica wet gel, immerse the silica wet gel in water for 30 minutes , and then add ethanol equal to the volume of water to continue soaking the silica wet gel for 12 hours, take out the silica wet gel, dry it in a 50°C oven for 1 hour, and grind to obtain silica airgel powder.

Abstract

The invention discloses a preparation method of heat-insulating and noise-resisting tempered glass. The preparation method comprises the following steps: S1, dispersing and stirring silicon dioxide aerogel powder, indium-doped zinc oxide, potassium titanate, bismuth oxide, a dispersing agent, an antifoaming agent, a leveling agent, a coalescing agent and water, then adding styrene-acrylic emulsion, and continuing to stir, so as to obtain a heat-insulating and noise-resisting coating, S2, taking plate glass, preheating the plate glass at 270-280 DEG C, then further preheating the plate glass at350-380 DEG C, then toughening the plate glass at 650-680 DEG C for 150-180 seconds, and then cooling the plate glass to 140-150 DEG C to obtain toughened glass, S3, coating the surface of the tempered glass with the heat-insulating and noise-resisting coating, and drying at 160-170 DEG C for 2-3 hours to obtain heat-insulating and noise-resisting tempered glass. The preparation method disclosedby the invention has the advantages that the prepared tempered glass is heat-insulating, sound-insulating and relatively small in thickness.

Description

technical field [0001] The invention relates to the field of tempered glass, more specifically, it relates to a preparation method of heat-insulating and noise-resistant tempered glass. Background technique [0002] With the rapid development of all walks of life, glass is more widely used in people's lives, involving construction, automobiles, furniture, information industries, etc. There are more and more types of glass, and tempered glass is a commonly used type of glass. Glass refers to the glass with compressive stress on the surface. The glass is strengthened by tempering. The compressive stress formed on the surface of the tempered glass makes the glass first offset the surface stress when it is subjected to external force, thereby improving the bearing capacity and enhancing the wind pressure resistance of the glass itself. and impact resistance. [0003] The function of tempered glass is relatively simple. In order to add heat insulation and sound insulation functi...
