Vacuum plating UV coating for PET plastic cement

Abstract

The invention discloses a vacuum plating UV coating for PET plastic cement. The vacuum plating UV coating for the PET plastic cement is prepared from, by weight, 10%-25% of polyurethane-modified acrylic acid oligomers, 10%-20% of polyester acrylate, 5%-15% of trimethylolpropane triacrylate, 1.5%-4% of alpha-hydroxycyclohexyl phenyl ketone, 1%-8% of 10% acrylic acid function resin, 2%-15% of methyl ethyl ketone, 35%-50% of ethyl acetate, 5%-20% of n-butyl acetate and 1%-8% of cyclohexanone. According to the vacuum plating UV coating for the PET plastic cement, the vacuum plating UV coating is a UV vacuum aluminum plating primer which has the excellent adhesion on a PET plastic cement substrate, the high fullness, the excellent levelling property and the wonderful plating effect are achieved; the defect of over crispness or pseudo adhesion of similar products is overcome, and the excellent overall adhesion effect can be supplied; the excellent physical and chemical properties and the excellent levelling property and fullness are achieved.

Description

technical field

[0001] The invention relates to the technical field of coatings, in particular to a PET plastic vacuum electroplating UV coating. Background technique

[0002] UV coating is a general term for all ultraviolet radiation curable coatings. Its film-forming method is that ultraviolet radiation triggers unsaturated double bond open-chain polymerization and quickly dries into film. No special process is required, and the overall performance is good; the coating with thin film That is, it has excellent fullness; particularly good adhesion; and very high gloss.

[0003] PET material (polyethylene terephthalate chemical formula is -OCH2-CH2OCOC6H4CO-English name: polyethyleneterephthalate) compared to widely used ABS material (acrylonitrile-butadiene-styrene copolymer, English name: AcrylonitrileButadieneStyrene) Said that due to its excellent physical and mechanical properties in a wide temperature range, the long-term use temperature can reach 120 ° C, excellent el...
