[0028] Correspondingly, a kind of preparation method of glass, comprises the following steps:
[0029] S01. Provide glass liquid, glass liquid contains SiO 2 、Al 2 o 3 , CaO, MgO, Na 2 O and Fe 2 o 3 , with SiO 2 The weight is 71.9-72.1 parts, Al 2 o 3 1.25-1.35 parts, CaO 8.65-8.75 parts, MgO 3.35-3.45 parts, Na 2 O is 13.4-13.6 parts, Fe 2 o 3 0.595-0.605 copies;
[0031] The glass preparation method provided in the embodiment of the present application adjusts the composition and content of the glass liquid, and prepares the glass by using the float process, thereby increasing the softening point temperature and hardening molding temperature of the glass, so that the transmission of the obtained glass The stripes are uniform in light and shade, clear in texture and high in glass quality, which is conduc...
Embodiment 1
[0040] This embodiment provides a kind of green glass original sheet, is made by adopting float process, and its preparation method comprises the following steps:
[0041] 1) forming molten glass, wherein, taking the total weight of the molten glass as 100 parts, the molten glass comprises: SiO 2 72 copies, Al 2 o 3 1.3 parts, CaO 8.7 parts, MgO 3.4 parts, Na 2 O 13.51 parts, K 2 O 0.3 parts, Fe 2 o 3 0.6 parts, SO 3 0.17 parts, TiO 2 0.02 copies;
[0042] 2) A cooling water bag is set in the high temperature zone of the tin tank; then, the molten glass flows into the tin tank containing molten tinmetal, so that the molten glass hardens and forms on the surface of the molten tin metal, and then the glass is collected.

Abstract
The invention relates to the technical field of glass preparation, and provides glass and a preparation method thereof. The glass provided by the invention is prepared from SiO2, Al2O3, CaO, MgO, Na2Oand Fe2O3, in terms of 71.9 to 72.1 parts by weight of SiO2, the content of Al2O3 is 1.25 to 1.35 parts, the content of CaO is 8.65 to 8.75 parts, the content of MgO is 3.35 to 3.45 parts, the content of Na2O is 13.4 to 13.6 parts, and the content of Fe2O3 is 0.595 to 0.605 part. The components and the content of the glass are adjusted; the softening point temperature and the hardening forming temperature of the glass are effectively increased under the condition that the original main body performance of the glass is kept unchanged, and the influence of a forming area in a float process on glass transmission stripes is reduced by promoting rapid forming and hardening of the glass, so that the quality of the glass transmission stripes is improved.
Description
technical field [0001] The application belongs to the technical field of glass preparation, and in particular relates to a glass and a preparation method thereof. Background technique [0002] The front windshield of a car is usually produced by sandwiching a layer of film between two original glass sheets with a thickness of 2.1mm. The quality of the original glass sheets used is directly related to the effect of the car glass. The quality of the transmission stripes is It is an inspection standard for judging the quality of automotive grade glass produced by float glass. The detection method of the quality of the transmission stripes is as follows: the direction of the light source and the direction of the glass plane form an angle of 45°, use a point light source to irradiate the glass plate, and project the stripes generated by the transmission onto the screen, and visually measure the brightness and uniformity of the stripes. If the lightness and darkness of the transm...
