Ultraviolet solidified coating and preparing method thereof

Abstract

An ultraviolet solidified paint suitable for DVD is prepared from active oligomer (aminoformate-acrylate ester), active diluent, optical trigger, diluent and other assistants. Its advantages are high adhesion to aluminium and polycarbonate plastics, and high resistance to salty fog, high temp and humidity.

Description

technical field [0001] The invention relates to an ultraviolet curing paint and a preparation method thereof. The paint of the invention is especially suitable for surface coating of polycarbonate plastics and aluminum plating, and has excellent adhesion to both. Background technique [0002] Since the advent of UV-curable coatings, it has attracted people's attention with its high-efficiency, energy-saving, and environmental-friendly features, and its application fields have become increasingly broad, especially in emerging high-tech fields. Applications. Since the end of the last century, digital technology has been widely used in communication, information storage and transmission, and UV-curable coatings have played an indispensable role in information transmission and storage equipment protection. So far, the global annual output of optical discs (VCD, DVD, etc.) is measured in billions, and their protection and decoration cannot be completed by traditional coating tec...
