Problems solved by technology

However, the coated optical lens with a medium thin film layer includes a wear-resistant layer (hard film), a multi-layer anti-reflection film and an anti-fouling film on the top film. It is difficult for the base coating composition to wet the surface of the coated lens, so that it cannot be coated, which seriously hinders the application of water-based coatings in this field

[0016] Preparation

[0017] First, add the water-based film-forming resin and the water-based wetting aid into the container, and stir for 2 hours with a high-speed disperser at a speed of 500 rpm, then add the water-based defoaming aid and anti-blocking additive in turn in the container, and then use the high-speed disperser. Stir at a speed of 500rpm for 1 hour, then add humectants and diluents in turn into the container, stir with a high-speed disperser at a speed of 500rpm for 10-15 minutes, and filter to obtain the composition.

Abstract

The invention relates to a temporary protective paint composition for a water base environment-friendly lens and a preparation method of composition. A temporary protective film of the paint composition, which is formed on a coating lens surface, can prevent surface abrasion, impurity absorption and center bias during lens transport, lens storage and lens dispensing processing, and the temporary protective film is easy to remove after lens dispensing processing. The problems of moist coating of water base paint on low surface coating lens surfaces are solved. The paint can replace conventional solvent based coating of the same type and is environment friendly.

Description

technical field [0001] The invention relates to a water-based environment-friendly lens temporary protective coating composition and a preparation method thereof. The coating composition is used for temporary protection of optical lenses with a dielectric film layer coating. Background technique [0002] Coated optical lenses are extremely vulnerable to contamination and damage during the process of finished product inspection and packaging before delivery, transportation and storage after delivery, and edging at final sales. Therefore, it is necessary to temporarily protect the optical lens during the above process. At present, there are mainly two methods for temporary protection of coated optical lenses: one is to use lens processing protection stickers, and the other is to use lens processing temporary protective coatings. The protective sticker is a kind of single-sided transparent film, which is pasted on both surfaces of the lens to achieve the protective effect. How...
