Embodiment

[0304] Hereinafter, some experimental examples related to the present invention will be described, but the present invention is not intended to be limited to the experimental examples. In addition, in the following description, "part" and "%" are based on weight unless otherwise indicated.

[0305]

[0306] [Ammonia content of adhesive (layer)]

[0307] About 10 mg of the adhesive component of the protective sheet to be measured was prepared, put into a container made of polypropylene (PP), and weighed. Next, 100 mL of ultrapure water was added, the lid was capped, and heat extraction was performed in a dryer at 120° C. for 1 hour. For the obtained extract, the amount of ammonium ions in the extract was quantified using a commercially available ammonium ion standard solution (obtained from FUJIFILM Wako Pure Chemical Corporation) by ion chromatography, and the amount of the binder used in per 1 g of extraction was obtained. amount of ammonia. The ion chromatography measur...

Abstract

The invention provides a Low-E glass plate protection method, whereby alteration of a Low-E layer may be prevented or suppressed. Provided is a Low-E glass plate protection method. This protection method for a Low-E glass plate involves pasting, via an adhesive layer, a protection sheet having a base material and the adhesive layer provided on at least one surface of the base material onto the Low-E layer of the Low-E glass plate equipped with the Low-E layer, which contains a zinc component, thereby protecting the Low-E glass plate. The method is characterized by using, as the protection sheet, a sheet wherein the adhesive layer is formed from a water dispersion type adhesive composition, and the ammonia content in the adhesive layer is less than 850 [mu]g / g relative to the adhesive layer weight, as measured by hot water extraction.

Description

technical field [0001] The present invention relates to a method for protecting a Low-E glass plate, a method for producing a glass unit, a laminate, and a protective sheet for a Low-E glass plate. [0002] This application claims priority based on Japanese Patent Application No. 2019-120483 filed on June 27, 2019, the entire contents of which are incorporated herein by reference. Background technique [0003] For the purpose of preventing damage (scratch, dirt, corrosion, etc.) on the surface of various articles when processing or conveying, there is known a technique of adhering a protective sheet to the surface to protect the surface. It protects a wide range of objects. For example, a glass plate with a Low-E (Low-Emissivity: low-emissivity) layer (Low-E glass plate) that has been widely used in recent years also uses a protective sheet. From the viewpoint of the effect of improving the cooling and heating efficiency of the indoor space brought about by the Low-E layer,...
