Abstract

The invention discloses a strippable resin which comprises the following components in parts by weight: 40-70 parts of polyvinyl chloride resin, 20-50 parts of plasticizer, 5-10 parts of epoxy compound, 2-5 parts of phosphite ester, 2-5 parts of polyhydric alcohol, 3-5 parts of stabilizing agent and 1-2 parts of thixotropic agent. The polyvinyl chloride resin is different polyvinyl chloride resins with polymerization degrees of 1000-1700 or a mixture thereof. The strippable protection coating disclosed by the invention is excellent in thermal aging resistance, shows excellent thermal stability in a high-temperature process of 150-160 DEG C, has no release of an HCl gas in the process, keeps a good strippability after being baked, has no residue after being stripped, thereby being free from generating corrosion and pollution to a protected ITO (Indium Titanium Oxide) line.

Description

technical field [0001] The invention relates to a manufacturing process of a touch panel, in particular to a method for preparing a high-temperature-resistant peelable protective coating. The peelable protective coating is mainly applied to conductive films or conductive glass and ITO coatings in the manufacture of touch panels. Temporary protection of lines. Background technique [0002] In recent years, the flat panel display industry has developed rapidly, especially the output of touch panels has increased rapidly. During the production process of the touch module, a strippable coating is required to protect the ITO lines on the conductive film or conductive glass from process pollutants or corrosion. Temporary protective coatings currently on the market cannot withstand the high temperature treatment process at 150°C for a long time, and HCl is released during the baking process, which has caused relatively great harm to the environment and human body. Moreover, it is...
