Toughened glass capable of resisting cold and thermal strain and preparation method thereof

Abstract

The invention discloses toughened glass capable of resisting cold and thermal strain and a preparation method thereof. A substrate of the toughened glass capable of resisting cold and thermal strain is prepared from the following components in parts by weight: 85-90 parts of silicon dioxide, 5-8 parts of boron oxide, 2-3 parts of sodium oxide, 6-10 parts of high-temperature-resistant organic silicon colloid subjected to partial cage type modification by linear main chain silicon-series organic matters, and 3-5 parts of graphite powder of which the particle size is 10-20mu m. A layer of nano titanium dioxide crystal film is also deposited on the surface of the substrate. The toughened glass capable of resisting cold and thermal strain has a low self-linear expansion coefficient, good toughness, high heat dissipation capability and good impact resistance, also has self-buffer performance, and is suitable for working conditions with large operating environment temperature difference in solidified frame sizes.

Description

technical field [0001] The invention relates to the field of glass products, in particular to a cold and heat strain-resistant tempered glass and a manufacturing method thereof. Background technique [0002] Tempered glass, that is, glass with compressive stress on the surface, can be obtained by physical or chemical methods in conventional technology. When the glass is subjected to external force, the surface stress is first offset, thereby improving the bearing capacity and enhancing the glass's own resistance to wind pressure, cold and heat, and impact. sex etc. These glasses do not have sharp edges when they break, making them safer. [0003] However, with the development of the times, residential buildings are getting taller and taller. The tempered glass in the prior art is limited by the high expansion coefficient of the glass itself, fixed outer frame, strong rigidity but poor toughness, poor heat dissipation performance, and no self-buffering performance. In high-...

[0003] However, with the development of the times, residential buildings are getting taller and taller. The tempered glass in the prior art is limited by the high expansion coefficient of the glass itself, fixed outer frame, strong rigidity but poor toughness, poor heat dissipation performance, and no self-buffering performance. In high-heat areas (such as Xi'an in summer), in high-cold areas (such as Heilongjiang in winter), in areas with large temperature differences between day and night (such as deserts) or in heating equipment, the window glass is easily affected by thermal expansion and contraction, and it is easy to crack, resulting in The hidden danger of falling objects from high altitude or the hidden danger of spraying and hurting people due to the high internal pressure
