Abstract

The invention discloses a vacuum-plated UV-cured primer, a preparation method therefor and an application of the vacuum-plated UV-cured primer. The vacuum-plated UV-cured primer comprises the ingredients in parts by weight: 8-30 parts of low-functionality acrylate, 3-12 parts of reactive diluent, 10-30 parts of epoxy acrylate, 0.01-0.5 part of auxiliaries, 2-3 parts of photoinitiator and 40-60 parts of organic environment-friendly solvent, wherein the low-functionality acrylate is aliphatic polycarbonate acrylate with the functionality of 1 to 4; and the epoxy acrylate is modified epoxy acrylate with the functionality of 1 to 4. According to the vacuum-plated UV-cured primer disclosed by the invention, the low-functionality acrylate, the reactive diluent and the epoxy acrylate serve as primary film forming matters, the reactive diluent can neutralize two kinds of prepolymers, and two kinds of prepolymers of different molecular structures can be rapidly crosslinked together to form cross-linked network knots and be cured to form a film, so that the vacuum-plated UV-cured primer is high in leveling and covering power and good in plating property.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a vacuum electroplating UV curing primer. In addition, the present invention also relates to a preparation method and application of the above-mentioned vacuum electroplating UV curing primer. Background technique [0002] At present, with the continuous progress of society and the continuous improvement of people's living standards, various electronic or electrical products, cosmetic packaging, digital cameras, notebook computers, mobile phones, cameras, MP3, MP4, electric toothbrushes, smart speakers, etc. have been widely used in people's daily life.
