High-temperature-resistant ink and preparation method thereof

Abstract

The invention provides high-temperature-resistant ink and a preparation method thereof. The ink is prepared from the following raw materials: inorganic-nano ceramic powder, rosin, a heat stabilizer, organic pigment, a heat-resistant additive, benzyl silicon resin, sodium phosphate, diamond micro powder, boric oxide, polyurethane and castor oil. The high-temperature-resistant ink provided by the invention has good high temperature resistance and abrasion resistance, further has an anti-static property, good chemical stability and good light resistance, can effectively keep out most sunlight radiation heat to achieve the purpose of environment friendliness, is good in luster after printing, meanwhile, is simple and feasible in preparation method, high in preparation efficiency, and dried quickly and has good economic benefits.

Description

technical field [0001] The invention belongs to the technical field of printing ink, and in particular relates to a high-temperature-resistant ink and a preparation method thereof. Background technique [0002] Ink is an important material for printing packaging materials. It expresses patterns and characters on the substrate through printing. The ink includes main components and auxiliary components. They are evenly mixed and rolled repeatedly to form a viscous colloidal fluid. Printing ink is a paste-like colloid formed by uniformly dispersing and mixing materials such as colorants, linking materials, additives, and solvents. The binder of solvent-based ink is composed of solid resin and a large amount of volatile organic solvent. After the solid resin is dissolved in the solvent, the coloring material is evenly dispersed in the binder, and after the ink is printed on the printing medium, the solvent quickly evaporates and dries the conjunctiva. For inks, it is generally...

Problems solved by technology

[0003] However, in the prior art, the ink used for printing is not strong in light resistance and high temperature resistance, poor in chemical stability, weak in adhesion, easy to fall off the pigment, and the applicable materials are limited.

At the same time, in order to ensure the printing quality, a large amount of highly toxic solvents such as benzenes and ketones are used in its preparation, such as hydrocarbon solvents such as solvents, aromatic solvents such as xylene and ethylbenzene, butyl acetate, etc. Ester solvent-based ink, when the solvent is not handled properly during the ink production process, it is easy to cause harm to the body of the production workers. When the ink is used for printing, the volatilization of the toxic solvent in the ink will also cause certain harm to the body of the printing workers , and there are often harmful substances in the dried ink, it is difficult to meet the requirements of green environmental protection, and it will inevitably affect the health of printed matter users and pollute the environment to varying degrees.
