Abstract

The invention relates to an aviation organic glass protective coating which contains the following ingredients: acrylic acid, polyethylene glycol, water-soluble polyether-modified polysiloxane, fumed silica, n-dodecyl mereaptan, potassium persulphate and water. The invention is mainly characterized in that the protective coating doesn't contain an organic solvent at all, has flexibility, can be used to protect optical functional polymer materials such as aircraft cabin glass during transportation and production processes, can conveniently be removed after implementing the protective function and will not influence optical performance of the materials.

Description

[0001] technical field [0002] The invention relates to a paint, especially a paint that does not contain organic solvents and protects optical functional polymer materials during transportation and production. [0003] Background technique [0004] Aircraft cockpit glass is a transparent plate made by bulk polymerization with methyl methacrylate as the main raw material, adding a small amount of additives, and under the action of an initiator, commonly known as aviation plexiglass. Aircraft cockpit glass has excellent optics, strength, heat resistance, aging resistance, and ultraviolet resistance. It has greater strength; its compressive strength, impact resistance and bending strength are higher than ordinary plexiglass, especially the oriented plate, its impact strength is more than twice that of ordinary plexiglass, and it also has high anti-silver streak It is not easy to break when subjected to vibration; it has good corrosion resistance and insulation, and is easy ...
