Formula and preparation method of peelable photocuring glass coating

Abstract

The invention discloses a peelable photocuring glass coating in which phosphorus-containing urethane acrylate, epoxy acrylate and ethyl acetate are used together as main body resin, and active monomers, photoinitiator, filling agents and other additives are also added. When glass is coated with the peelable photocuring glass coating, not only is a good protection function achieved for the glass, but also a good peeling property is achieved. Meanwhile, a preparation method and a use method of the coating are both energy-saving and environment-friendly, the cost of a procedure of glass surface protection can be effectively lowered, a soft film can be formed, and the machining process is not affected.

Description

technical field [0001] The invention relates to a light-curing glass coating, in particular to a formula of a strippable and easy-peeling light-curing glass coating, a preparation method and a use method thereof. Background technique [0002] In high-end consumer products such as 3C products and decorations, glass parts are often used as display screens and exterior decorations, and are a very important part of product appearance. However, in the process of deep processing of finished products, glass products are very easy to be scratched, resulting in a low yield rate of finished glass products and increased costs. At present, in many glass processing processes, a layer of protective ink is coated on the surface of the glass before mechanical processing. Ink removal, restore the appearance of glass, such as the alkali-washable UV paint provided in the patent named "A kind of alkali-washable UV paint for mobile phone glass bottles and its preparation method" with applicatio...

Problems solved by technology

Using the above method of protecting ink, although it can have a good protective effect on the surface of the glass, there are several obvious problems: (1) The lye cleaning steps are relatively cumbersome, and often need to include alkali cleaning, pickling neutralization, and clear water Washing, ultrasonic cleaning and other steps, often need to be heated during alkaline cleaning, which brings certain safety hazards and the problem that the waste liquid generated is difficult to handle, and lacks energy saving and environmental protection; (2) The alkaline cleaning step in the process The requirements are very high to prevent damage to the glass surface and other components of the product; (3) Alkali-soluble protective inks often have high hardness after film formation, which has an impact on subsequent mechanical processing and is easy to damage processing tools such as CNC cutter heads
