example 1

[0019] Weigh 80g polyurethane and 10g aluminum silicate powder and mix and stir for 7min. After stirring, add 30mL nano tin oxide antimony dispersion with a mass fraction of 10% and 20mL deionized water. After mixing and stirring for 30min at 75℃, continue to add 10mL propylene glycol butane Ether, 4mL corn oil and 5g gelatin, continue to mix and stir at 115℃ for 1h to obtain a self-made thermal insulation mixture. In parts by weight, weigh 8 parts of terephthalic acid, 3g parts of antimony oxide, and 8 parts of ethylene dichloride. Alcohol and 3 parts of phosphoric acid were placed in a beaker, stirred and reacted at 240°C for 1 hour to obtain polyethylene terephthalate. The polyethylene terephthalate was put into a twin-screw extruder and the thickness was The 2cm resin sheet is extruded and then biaxially stretched into a film with a thickness of 0.12mm, which is a polyester film. The sandblasting machine is driven by compressed air to form a high-speed jet beam. 3 parts of q...

Abstract

The invention discloses a method for improving anti-explosion and thermal-insulating heat-preservation effects of glass, and belongs to the technical field of glass preparation. According to the invention, firstly a polyester film is taken as a matrix, and quartz sand powder is utilized to modify polyester, wherein the polyester is a thermal-insulating heat-preservation material and can reflect 90% or more of a red ultraviolet ray, so that the thermal-insulating heat-preservation effects of the thermal insulating glass can achieve a very long time, and under a high temperature, the heat-resistant quartz sand powder is promoted to uniformly disperse at the surfaces of the polyester and other substances; and polyvinyl butyral resin and silicone rubber in a sandwich layer are added continuously to promote the adhesion performance with other substances, methyl is arranged outwards and can be rotated freely, so that the silicone rubber has better heat resistance, high strength, chemical stability and the like, the thermal insulating glass has the anti-explosion characteristics, even if the glass breaks, fragments do not splash everywhere, the use security of the thermal insulating glassis reinforced, the thermal insulation performance and anti-explosion performance of the thermal insulating glass are further improved, and the obtained thermal insulating glass has wide application prospects.

Description

Technical field [0001] The invention discloses a method for improving the explosion-proof and thermal insulation effects of glass, and belongs to the technical field of glass preparation. Background technique [0002] Glass is a material with high transparency, strength and hardness, and is not air-permeable. Glass is chemically inert in the daily environment and will not interact with organisms. Therefore, it has a wide range of uses. The glass used in buildings in the prior art is mainly used for sealing, lighting, and heat preservation. However, in winter in cold regions, the thermal insulation effect of glass is not ideal, and in summer in hot summer and cold winter regions or hot summer and warm winter regions, the thermal insulation effect of glass is not ideal. At the same time, with the rapid development of my country’s economy, people’s requirements for the quality of life are getting higher and higher, and building doors, windows, and glass curtain walls are getting bi...
