Problems solved by technology

At present, the existing PET film surface treatment primers mainly include solvent-based polyurethane and solvent-based saturated polyester resins. They are generally two-component thermosetting primers, which have no problem with the adhesion of the PET material itself. The main disadvantages are as follows: First, for some UV inks and UV coatings, especially for UV inks and coatings prepared with high-functionality epoxy-modified acrylic oligomers or high-functionality polyurethane-modified acrylic oligomers with high hardness Adhesion is still poor; second, the existing primers take a long time to heat and consume a lot of energy, and it is difficult for general coating machinery to adapt; third, the construction operation of the existing primers releases a large amount of volatile organic compounds (VOC)

Abstract

The present invention discloses an ultraviolet-curable PET film surface treatment bottom sizing agent and a preparing method and an application thereof. The ultraviolet-curable PET film surface treatment bottom sizing agent is characterized by comprising, based on the mass percentage of 100%, 45% -55% of difunctional aliphatic carbamate-acrylate oligomers; 15% -20% of a trifunctional reactive diluent of trihydroxymethylpropyl trimethylacrylate; 15% -20% of a bifunctional reactive diluent of tripropylene glycol diacrylate; 1.5%-2.5% of a photo initiator of 2-hydroxy-2-methyl -1-phenyl acetone; 1.5% -2.5% of a photo initiator of 1-hydroxy cyclohexyl phenyl ketone and 5% -15% of ethyl acetate. The ultraviolet-curable PET film surface treatment bottom sizing agent of the invention can be applied to PET decoration materials, label materials and PET protective film surface treatment, and can improve adhesive force of UV ink and coatings.

Description

technical field [0001] The invention belongs to the technical field of environment-friendly coating materials, and in particular relates to an ultraviolet-curable PET film surface treatment primer and a preparation method and application thereof. Background technique [0002] PET film has good heat resistance, high transparency and strength, is not easy to stretch, and has lower tension control requirements than other films. It is more and more widely used in labels, membrane switches, protective films and other fields. Due to the regular structure of PET macromolecular chains and high crystallinity, its surface affinity, printability and ink adhesion fastness are poor. UV coatings and UV inks generally have good durability and solvent resistance, and have the characteristics of environmental protection and energy saving. In recent years, their market share has been increasing continuously. meet application requirements. Improving the adhesion of UV coatings and inks on PE...
