Problems solved by technology

Therefore, in the manufacturing process of glass substrates, after washing with water, it is usually necessary to install a separate production line for processing, and the economic burden is large.
Moreover, once a surface is coated with such a treatment, its removal is very difficult

Embodiment 1～10

[0126]On the entire area of ​​one main surface of a glass substrate made of non-alkali borosilicate glass of 470 mm × 370 mm × thickness 0.7 mm that has been subjected to surface grinding, apply 100 mL of the solution for forming an anti-adhesion film obtained above with a sponge. 1. Form a coating film. After this coating, leave it for 20 to 30 seconds to obtain a glass substrate with a coating film, wash the glass substrate with water by spraying it, and then use air blast (room temperature) to blow off the water droplets to dry the coating film, thereby An anti-adhesion film was formed on one main surface of the glass plate to obtain an anti-adhesion film-attached glass plate 1 .

[0127] The obtained 300 glass plates 1 with the anti-adhesion film were alternately laminated with the glass plate 1 and the backing paper to form a glass plate laminate, which was housed and packaged in a vertical glass plate packaging container. At this time, the anti-adhesion film of the glas...

Abstract

The present invention provides a glass plate laminate in which the peelability of a backing paper is improved when a glass plate is used, and a packaging method thereof. A method for packaging a glass plate laminate, which is a method for packaging a glass plate laminate 10 formed by alternately laminating glass plates and backing paper 30 that prevents the glass plates from contacting each other, wherein the glass plate has an adhesion-preventing film on its surface. A glass plate 1 with an anti-adhesion film of the film, the anti-adhesion film contains: a cationic surfactant containing a quaternary ammonium salt or a pyridinium salt having a hydrophobic group having 8 or more carbon atoms, the average molecular weight It is a cationic polymer of 2 million to 1 million, or a zwitterionic compound having a cationic group and an anionic group in one molecule.

Description

technical field [0001] The present invention relates to a glass plate laminate and a packaging method thereof, and more particularly to a glass plate laminate and a packaging method thereof among glass plates having an anti-adhesion film. Background technique [0002] In recent years, there has been an increasing demand for larger glass plates used in flat panel displays such as glass substrates for liquid crystal displays and glass substrates for plasma displays, organic EL lighting, and electronic devices such as solar cells. [0003] Such a glass plate is transported to a factory where it is processed into a product after being processed into a plate shape, or is stored. In this transportation and storage, conventionally known are the vertically placed glass plate packages disclosed in Patent Documents 1 and 2 and the horizontally placed glass plate packages disclosed in Patent Document 3, which are usually sandwiched between glass plates. Stacked with backing paper for ...
