Problems solved by technology

In order to meet the requirements of the industry, domestic ink manufacturers use imported solvents as raw materials to produce high-end color ink products, which is expensive
Disadvantages of solvent oil for color inks used in the past: ① The water resistance of solvent oil is not good; ② Slow penetration of solvent oil; ③ The solubility and release performance of solvent oil to resin are not balanced; deep

Embodiment Construction

[0028] Such as figure 1 process figure 1 , Technological process description: base oil → solvent refining → white clay decolorization and refining → compound agent blending → refined oil.

[0029] 1. Production process: Color ink solvent oil is made of naphthenic crude oil fractions, special solvent dearomatization process, clay decolorization and refining process to produce base oil, and then blended with unique compound additives. The specific operation steps are as follows:

[0030] Solvent Refining:

[0031] 1) The naphthenic crude fraction C1 and N46 base oils are separated and fused by a static mixer according to the ratio of 7:3, poured into the reaction kettle, heated by the built-in heating coil, and the temperature is controlled at 30-40 ℃.

[0032] 2) Measure a certain amount of R2 solvent (base oil: R2=98.5:1.5), and slowly add the R2 solvent into the reaction kettle. During the addition, first start the agitator and control a certain stirring speed.

Abstract

The invention relates to a preparation method of color printing ink solvent oil. The color printing ink solvent oil is prepared by utilizing naphthenic base crude oil fractions, adopting a special dearomatization process and a clay decoloring and refining process to produce base oil and adding proportioned unique compound additive, i.e. the solvent-refining process and the clay decoloring and refining process are carried out to the base oil which is then proportioned by a complex additive to finally prepare finished oil. The method does not generate aromatic toxicity and lessens damage to human beings; the color printing ink solvent oil keeps balance between the dissolving capacity and the release property of resin, solves the problems of unstable product indexes, such as water resistance,penetrability, and the like and has good printing performance, printing stability and storage stability of printing ink, light colors, good water resistance, strong penetrability, suitable aniline point, balanced dissolving capacity and release property to resin, no pungent odor and environmental protection. A printing ink product manufactured by the product has good printing quality, thick printing layer, uniform and full colors, bright colors and luster and strong printability.

Description

technical field [0001] The invention belongs to printing ink solvent, in particular to a kind of color ink solvent oil and its preparation method. Background technique [0002] Ink solvent oil is used in the ink industry, accounting for 65-70% of ink production, is the main component of ink, and plays the role of dissolution and dilution. The quality of ink directly determines the printing effect, so the quality of ink solvent oil restricts the development of printing industry to a certain extent. Ink is divided into black ink and colored ink in color, therefore, ink solvent oil is also divided into black and colored in color. [0003] In the past, domestic color inks used ordinary N32 or N46 mechanical oil as solvent oil, and the quality of the ink products produced was relatively low, which was suitable for printing equipment and processes in the 1980s and 1990s. Later, with the development of the printing industry, The ink solvent oil can no longer meet the requirements...
