[0327] [Evaluation of discoloration of Low-E glass plate]

[0328] The protective sheet was cut into strips with a width of 20 mm and a length of 100 mm to prepare test pieces. In a standard environment of 23° C. and 50% RH, a 2 kg rubber roller was reciprocated twice to press-bond this test piece to the surface of the Low-E layer of the Low-E glass plate for testing as an adherend. After storing this sample in an environment of 40° C. and 92% RH for 2 weeks, the protective sheet was peeled off, and the state of the surface of the glass plate in the region protected by the protective sheet was observed with an optical microscope. The case where discoloration was not observed w...

Abstract

Provided is a protection method for Low-E glass plates that makes it possible to prevent or suppress the deterioration, corrosion, etc. of a Low-E layer. The protection method includes a step for sticking a protective sheet onto the surface of a Low-E glass plate that comprises a Low-E layer. The Low-E layer includes a tin component. The protective sheet comprises an adhesive layer. The adhesive layer includes a phosphorous compound that has a P-OR group. R is a hydrogen atom or an organic group.

Description

technical field [0001] The present invention relates to a method for protecting a Low-E glass plate, a method for preventing and suppressing deterioration of a Low-E glass plate, a method for manufacturing a Low-E glass plate, 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. 2019-120485 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 effec...
