Problems solved by technology

Due to the difference and incompatibility between the polarity of the traditional oil-based offset printing ink and UV offset printing ink, when the two inks are mixed, gelation occurs and cannot be used for printing—this is the fundamental reason why mixed ink products cannot be prepared

Abstract

The invention provides an ink binder as well as a preparation method and application thereof, and relates to the technical field of printing. The ink binder provided by the invention is prepared from the following raw materials in percentage by mass: 10-20% of oil-soluble resin containing an ester structure, 10-20% of oil-soluble and ester-soluble resin, 10-30% of vegetable oil and / or derivatives, 1-10% of mineral oil, 10-20% of ester-soluble resin, 10-30% of acrylate monomer and 5-20% of acrylate with an isocyanate group. The ink binder provided by the invention has excellent solubility in vegetable oil and mineral oil, also has excellent solubility in an acrylate monomer, and can be suitable for production of mixed ink. The ink binder provided by the invention has UV-LED curing and oxidation film-forming drying performances, and is suitable for nitrile rubber, ethylene propylene rubber and dual-purpose rubber rollers.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to an ink binder and its preparation method and application. Background technique [0002] At present, the inks suitable for offset printing on the market are mainly divided into two categories: traditional oil-based offset printing inks and UV offset printing inks. Traditional oil-based common offset printing inks are mainly composed of pigments, vegetable oils, mineral oils, rosin-modified phenolic resins, and alkyd resins. For general absorbent substrates, such as coated paper, cardboard, etc., choose an ink containing high mineral oil. After the ink is printed, the mineral oil penetrates into the paper to form osmotic drying, and then oxidizes the conjunctiva with vegetable oil to form a firm colored ink layer. On non-absorbent substrates, such as synthetic paper, choose inks that do not contain or a small amount of mineral oil, and completely pass through the oxidized conjunc...
