Anti-clogging and high-temperature-resisting polyvinyl butyral spray ink

Abstract

The invention relates to the field of printing ink and particularly relates to anti-clogging and high-temperature-resisting polyvinyl butyral spray ink. The ink is prepared from the following raw materials in parts by weight: 0.2-0.5 part of glyzinc, 2-5 parts of lauryl alcohol polyoxyethylene, 0.1-0.2 part of lithium acetate, 6-8 parts of a magnesium ferrite pigment, 24-32 parts of dimethyl carbonate, 3-5 parts of phenyl salicylate, 2-3 parts of stearyl alcohol, 8-12 parts of absolute ethyl alcohol, 26-35 parts of polyvinyl butyral resin and 1-2 parts of auxiliaries. The ink takes the polyvinyl butyral resin as an adhering material, is good in softness and flexibility and good in transparency, can resist light and cold, and can be adhered to the surfaces of various kinds of materials well. The lithium acetate and the glyzinc can prevent the ink from crystallizing and improve the heat resistance of coatings, and the auxiliaries can improve the wettability of ink so as to enable the ink to be easily sprayed. The ink has the advantages of low toxicity, environmental friendliness, controllable viscosity and good liquidity, is prevented from color change and falling off in high-temperature environment, is moderate in drying speed, is not easily clogged, and is efficient in spraying.

Description

technical field [0001] The invention relates to the field of printing ink, in particular to an anti-blocking and high-temperature resistant polyvinyl butyral spraying ink. 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 text and patterns by printing. It is a kind of viscous colloidal fluid. It is widely used in various printing such as books, packaging and decoration, and architectural decoration. With the increase of social demand, the variety 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 the inevitable direction of ink development in the future. [0003] The factors that affect the performance of the ink are mainly the properties of the components such as pigments, binders, fillers and additives. For example, pigments affect the durability and tinting strength of t...
