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...

Problems solved by technology

However, since the special active diluent in the whole formula plays a decisive role in affecting the performance, it will inevitably lead to an increase in product cost and difficulty in purchasing raw materials. This situation is more prominent in the bonding of DVD discs

There are also UV-curable coatings prepared by dissolving saturated resins in monomers for optical disc protection, but the protective performance of this type of coating is relatively poor, and the use effect is not completely satisfactory.
