Description

Technical Field

[0001] The invention belongs to the technical field of tempered glass manufacturing, and specifically relates to high-strength explosion-proof tempered glass and a preparation process and application thereof. Background Art

[0002] Tempered glass is a kind of glass with compressive stress on the surface. In order to improve the strength of glass, chemical or physical methods are usually used to form compressive stress on the glass surface. 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 wind pressure resistance and impact resistance. With the rapid development of China's economy, the demand for tempered glass in all walks of life has increased dramatically. In the construction industry, tempered glass has also shown many uses. For example, it can be used as anti-vibration and anti-collision parts such as door and window glass, partitions and public places, so there are extremely high requirements for the various properties of tempered glass.

[0003] At the same time, compared with ordinary glass, tempered glass also has the defect of self-explosion. There are many reasons for the self-explosion of tempered glass, among which the phase change of nickel sulfide crystals is the main cause of the self-explosion of tempered glass. Nickel sulfide is a crystal with two crystal phases, high-temperature phase α-NiS and low-temperature phase β-NiS. The phase change temperature is 379°C. In the process of preparing tempered glass, the heating temperature is much higher than the phase change temperature of nickel sulfide, so that all nickel sulfide is converted into high-temperature phase α-NiS. In the subsequent rapid cooling process, the high-temperature phase α-NiS has no time to convert into low-temperature phase β-NiS and is frozen in the tempered glass. At room temperature, the high-temperature phase α-NiS is in an unstable state and has a tendency to gradually transform into low-temperature phase β-NiS. This transformation is accompanied by a volume expansion of 2% to 4%, which makes the tempered glass bear huge phase change tensile stress, thereby causing the tempered glass to self-explode. Therefore, the performance of tempered glass used in buildings needs to be further improved, and the self-explosion rate also needs to be further reduced. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a high-strength explosion-proof tempered glass and a preparation process and application thereof, with the purpose of preparing a high-strength explosion-proof tempered glass for construction, so that the prepared tempered glass for construction has good impact strength, bending strength and surface compressive stress, and at the same time has a low self-explosion rate.

[0010] Furthermore, in step S1, the mass percentages of the substances in the glass liquid are: SiO 2 50~60%, B 2 O 3 3~4%,Al 2 O 3 4-7%, CaO 5-7%, Na 2 O is 9-13%, K 2 O is 7-9%, MgO is 5-8%, Fe 2 O 3 0.01~0.05%, ZrO 2 4-7%, PbO 1-3%, Bi 2 O 3 It is 1~4%, and ZnO is 1~3%.

[0011] Furthermore, in step S3, the gradient temperature increase is to increase the temperature to 510°C at a rate of 15°C / min, keep it warm for 2 to 4 minutes, then increase the temperature to 600°C at a rate of 10°C / min, keep it warm for 5 to 8 minutes, and then increase the temperature to 680 to 720°C at a rate of 5°C / min.

[0012] Further, in step S3, the radiation dose rate of the gamma ray is 3.6-15.6 kGy / h.

[0017] The present invention also provides a high-strength explosion-proof tempered glass, which is prepared by using the above-mentioned preparation process of the high-strength explosion-proof tempered glass.
