Problems solved by technology

[0005] At present, the composite printing inks used in the market are mainly divided into two categories: one is the composite ink with PVB resin as the main resin, which has the advantages of strong adhesion, good light resistance and water resistance, but is affected by the characteristics of the ink resin itself. , the high-speed printing suitability is not good, it is difficult to meet the current high-speed printing requirements; the other is a composite ink based on alcohol-soluble polyurethane resin, which uses alcohol-soluble polyurethane resin as the main resin, and has obvious advantages in printing adaptability. However, the alcohol-soluble polyurethane resin itself is very viscous, and some modified resins with excellent anti-adhesive properties need to be added to improve the anti-blocking performance of the ink, which leads to low composite strength of the ink in the post-processing composite process, especially in the solvent-free composite process. is particularly prominent in
At the same time, because chlorinated polypropylene with low chlorine content does not dissolve well without toluene, chlorinated polypropylene with high chlorine content can be completely fat-soluble and has excellent printing suitability, but when casting and compounding, the composite strength is low, especially in winter. composite strength requirements

Abstract

The invention belongs to the technical field of printing ink application, and concretely discloses a BOPP environment-friendly type inner printing ink. The BOPP environment-friendly type inner printing ink comprises the following raw materials by weight percentage: 22-25% of resin liquid A, 8-10% of a pigment, 3-10% of a filling material, 2-5% of modified rosin, 0.3-1% of a dispersant, 8-10% of ethyl acetate, and 40-50% of n-propyl acetate. The BOPP environment-friendly type inner printing ink and a preparation method have the beneficial effects that on one hand, printing adaptability is good,viscosity resistance is good, combined strength is high, and printing requirements of a plurality of composite technologies can be satisfied; on the other hand, low-chlorinity chlorinated polypropylene is used for removing a benzene solvent, a standard of a non-benzene printing ink is achieved, and the ideal combined strength can be achieved.

Description

technical field [0001] The invention belongs to the technical field of ink application, and in particular relates to a BOPP environment-friendly lining ink and a preparation method thereof. Background technique [0002] Ink (ink, printing ink) is an important material for printing. It expresses patterns and characters on the substrate by printing or inkjet painting. The ink includes main components and auxiliary components, which are uniformly mixed and rolled repeatedly to form a viscous colloidal fluid, which is composed of linking materials (resins), pigments, fillers, additives and solvents, etc. It is used in books, periodicals, packaging Decoration, architectural decoration and electronic circuit boards and other printing, as the social demand increases, the variety and output of inks also expand and increase accordingly. [0003] Pigments include pigments and dyes. Pigments are divided into organic pigments and inorganic pigments. The former has bright hues, strong t...
