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...

Problems solved by technology

However, the surface tension of PET materials is extremely low, so it is very difficult to coat them. Many factories use pre-treatment agents, corona or chromic acid treatment when coating PET materials, otherwise it is difficult to have good adhesion.

However, some existing PET coatings on the market have more or less poor leveling, poor fullness, poor toughness, false adhesion (the adhesion was good at the time, but fell off after a few days of testing), poor coating performance, and the plating layer is uneven. Color and other issues
