Problems solved by technology

[0005] Due to its good chemical and mechanical properties, light-curable inks can be used in fields that require high performance of ink products. Although the performance of existing light-curable ink products is relatively good, it can meet the requirements of most downstream processes, but In some fields with specific requirements, targeted ink products are still needed to meet their needs. Therefore, continue to develop an ink with good hardness and toughness to meet the needs of certain downstream manufacturing processes that are resistant to bending and scratches. demand is necessary

Abstract

The invention provides a preparation method of a photocuring printing ink, in parts by weight, 3,4-epoxy cyclohexyl methyl, 3,4-epoxycyclohexyl formate, bis((3,4-epoxycyclohexyl)methyl)adipate, epoxyactivated agarose gel with high flow rate, an epoxy modified polyvinyl butyral dispersion pigment, 2,4,6-ethyl trimethylbenzoyl phosphonate, nano titanium dioxide, a leveling agent and a defoaming agent are added into a reaction kettle, are stirred with the rotating speed of 300-600 r / min for 1-4 h, and are ground into the fineness of less than 15 [mu]m, and thus the photocuring printing ink composition product is obtained.

Description

Technical field [0001] The invention relates to a method for preparing an ink composition, in particular to a method for preparing a photocurable ink. Background technique [0002] Light-curable ink refers to the ink that makes the ink film and dry under the irradiation of ultraviolet light. The color film of the ink has good mechanical and chemical properties. It is widely used in metal mobile phone shell, digital camera, MP4, notebook shell and other industries. At present, UV ink has become a relatively mature ink technology, and its pollutant emission is almost zero. In addition to being solvent-free, UV ink has the advantages of not easy to paste, clear dots, bright and bright ink, excellent chemical resistance, and low dosage. It is useful in a wide range of applications. [0003] CN106398385A discloses a light-curable ink for transfer printing, which is characterized in that the components and weight percentages contained in the ink are: multifunctional polyurethane acryli...
