Nano barium titanate coated alkyd resin type printing ink

Abstract

The invention relates to the field of printing ink, in particular to nano barium titanate coated alkyd resin type printing ink. The printing ink is prepared by raw materials in parts by weight as follows: 2-4 parts of polymethyl methacrylate, 1-3 parts of nano barium titanate, 6-10 parts of PLGA (poly(lactic-co-glycolic acid) copolymer, 1-2 parts of oleic acid, 15-20 parts of proprylene glycol monomethyl ether, 8-24 parts of alkyd resin, 10-12 parts of ethyl acetate, 4-5 parts of absolute ethyl alcohol, 2-5 parts of alumina gel, 10-15 parts of a pigment and 1-2 parts of an assistant. The printing ink takes a mixture of the alkyd resin and the PLGA copolymer as a vehicle, has excellent adhesion and is good in compatibility with all components; nano barium titanate after dispersion treatment by an alumina gel alcoholic solution is uniformly dispersed in a resin solution more easily, so that the hardness and heat resistance of a coating are improved, the wettability of the printing ink can be improved by the assistant, and coating bubbles are avoided and prevented from affecting the decoration effect; and the printing ink has good printability in an actual use process and can be prevented from decoloration and shading for a long time at higher environment temperature.

Description

technical field [0001] The invention relates to the field of printing inks, in particular to an alkyd resin ink coated with nanometer barium titanate. Background technique [0002] Ink is a kind of coloring material that is very commonly used in daily life. It is used as the carrier of characters and patterns by printing. It is a viscous colloidal fluid. It is widely used in various printings such as books, periodicals, packaging and decoration, and architectural decoration. With the increase of social demand, the types and output of inks have also expanded and increased accordingly. Improving the performance of inks and achieving an energy-saving and efficient production mode is always an inevitable direction for the development of inks in the future. [0003] The factors that affect the performance of ink mainly lie in the performance of components such as pigments, linking materials, fillers and additives. For example, pigments affect the durability and tinting strength o...
