Description

Technical Field

[0001] The invention relates to the technical field of glass production, and in particular to a self-explosion-proof flexible glass and a preparation method thereof. Background Art

[0002] Glass has excellent light transmittance and is widely used in the fields of construction, transportation, and automobiles. Glass is generally prepared by the float process. Due to the characteristics of current technology and process, it is inevitable that there will be defects and foreign impurities remaining. In the actual engineering use process, due to the alternating changes in ambient temperature and humidity, the glass will produce thermal expansion and contraction effects. Due to the presence of defects and foreign impurities, the glass will explode from time to time, causing the glass to shatter and fall. In addition to causing major safety accidents, it also brings about problems such as high replacement costs and difficult construction. The method of laminating in the middle can avoid injuries caused by self-explosion, but it cannot fundamentally solve the problem of self-explosion, and the laminating process is complicated, which reduces the product life.

[0003] Patent CN109572109B The present invention discloses laminated glass, including an upper ultra-white coated glass layer, an SGP film and a lower ultra-white coated glass arranged in sequence from top to bottom; The present invention also discloses a method for preparing laminated glass, including the following process steps: original sheet → slicing → edge grinding → cleaning → tempering → coating → cleaning → sheet assembly → initial pressing → vacuuming → autoclave heating and pressurization → autoclave heat preservation and pressure maintenance → autoclave cooling and pressure reduction → autoclave trimming and finishing → finished product → finished product packaging → delivery. The present invention improves the uniformity of glass heating by improving the heating method to a heating tube plus a convection fan, improves the heating efficiency of the glass, improves the visible light transmittance and strength of the SGP laminated glass, shortens the production time of the SGP laminated glass, and reduces energy consumption.

[0004] The uniformity is mainly improved by improving the heating process, but the self-explosion caused by the ambient temperature during use cannot be avoided. The production process includes 17 steps and the process is complicated.

[0005] Patent CN113863823A The present invention discloses an anti-self-explosion glass, which relates to the field of glass explosion-proof. The anti-self-explosion glass has a protective rubber pad installed on the outer surface of the reinforced glass, a protective shell installed on the outer surface of the protective rubber pad, a metal anti-collision strip fixedly installed on one side of the protective shell, and a limit groove is provided on the upper and lower sides of the fixed frame, and an assembly groove is provided on one side of the fixed frame. The other side of the fixed frame is movably connected with a fixing strip inside the limit groove and the assembly groove, and the outer surface of the connection of the four groups of fixing strips is fixedly installed with an L-shaped connecting strip by screws. The anti-self-explosion glass ensures that the frame of the reinforced glass is effectively protected, and avoids the self-explosion of the reinforced glass due to collision during use. At the same time, when the protective rubber pad is aged and hardened, it is convenient to replace the protective rubber pad.

[0006] The main method is to add a protective shell to prevent the glass from falling after self-explosion, but it cannot avoid the self-explosion caused by the ambient temperature during use. Therefore, a self-explosion-proof flexible glass and a preparation method thereof are needed. Summary of the invention
