Problems solved by technology

[0004] At present, there are three main types of matting oil for surface printing: the first is the ink with polyamide and nitrocellulose as the binder, but it has poor temperature resistance and anti-adhesion and is not environmentally friendly; the second is the ink with acrylic acid and nitrocellulose as the binder. But there is a slight smell and the adhesion fastness is not good; the third is the ink with polyurethane and vinyl vinegar as the binder, which is suitable for high temperature cooking at 121°C for 30 seconds without sticking and yellowing resistance.

Abstract

The invention provides scratch-resistant plastic surface printing extinction oil and a preparation method thereof. The surface printing extinction oil comprises the following components: 20-30% of a vinyl chloride-vinyl acetate resin solution, 15-25% of a polyurethane solution, 1-5% of an auxiliary agent, 10-20% of a filler, 1-3% of polyethylene wax and 25-40% of a mixed solvent. By adding polyurethane and vinyl chloride-vinyl acetate resin, the cooking resistance of the ink is improved, and by adding the scratch-resistant agent, the scratch resistance of the ink is remarkably improved, so that the produced ink has the characteristics of scratch resistance (no scratch after fingernail scratching), high temperature resistance, no discoloration, safety, environmental protection and high stability, and the product of the PET base material is packaged, after extinction oil is printed on the back face according to the design layout, the extinction film printing effect can be achieved, meanwhile, the bright layer and the dark layer are clear, the emphasizing effect is prominent, and the packaging aesthetic feeling is enhanced. At present, online shopping is popular, a plurality of dried fruits, red dates, masks and other products sold online are packaged by adopting the package, and the market demand becomes larger and larger.

Description

technical field [0001] The invention relates to a high-scratch-resistant surface printing matting oil and a preparation method thereof, which meet the national VOC (volatile organic compound) discharge standard. In particular, it relates to a highly scratch-resistant system filler, which can provide excellent scratch-resistant performance and other surface properties. The invention discloses a green and environment-friendly high-scratch-resistant plastic surface printing matting oil which adopts an ester-soluble polyurethane resin with excellent film-forming and leveling as an ink main binder and a preparation method thereof. Background technique [0002] The printer is one of the output devices of the computer. It is used to print the computer processing results on the relevant media. The printer needs to consume ink during use. Due to the low dust and environmental protection of the pre-dispersed product and the high dispersion, high transparency, and The many advantages ...
