Problems solved by technology

The products obtained by the first three methods have high aniline points and poor solubility with ink resins, so more expensive true solvents—dry vegetable oils must be used to enhance the solvent system’s ability to dissolve resins, which will inevitably increase the ink’s solubility. cost
The product obtained by the fourth method has a high pour point and poor low-temperature fluidity, and its rapid solvent release performance is not ideal when applied to lithographic offset printing color inks
The above-mentioned methods all adopt petroleum-based raw materials to prepare ink solvent oil, and its product has a high aniline point and poor solubility with ink resin

Abstract

The invention relates to ink solvent oil and a preparation method thereof. The preparation method takes shale oil or coal tar as a raw material and comprises the following steps: pre-separating raw materials: distilling raw materials to obtain heavy oil and light oil; hydrocracking the heavy oil: hydrocracking the heavy oil to obtian hydrocracked oil; hydrorefining: hydrorefining the obtained light oil to obtain hydrorefined oil; and separating by distillation: separating the hydrorefined oil by distillation, and preparing cut fractions in a temperature range of 230 to 360 DEG C to obtain the ink solvent oil. The ink solvent oil has the characteristics of narrow distillation range, high flash point, light color, low aromatic content, good solubility for a resin, and the like, makes ink have good flowability, excellent delivery and fast solvent release and have relatively good high temperature stability and excellent dot reproducibility and gloss performance, is easily separated out from the ink, is good in storage stability and can be used as newspaper ink or colored ink solvent oil.

Description

technical field [0001] The invention relates to a solvent oil and a preparation method thereof, in particular to an ink solvent oil used for lithographic offset printing and printing ink and a preparation method thereof. Background technique [0002] Ink solvent oil is the main raw material for ink production, accounting for 60% of the total ink raw materials. Lithographic offset printing ink solvent oil is an important part of offset printing ink binder. It is neither the true solvent nor the co-solvent of the offset ink resin, but acts as a diluent. The binder is diluted with the help of ink solvent oil, so that the viscosity of the ink is reduced, and the filling in the lithographic ink The input amount is about 30%. In the printing process, when the ink solvent oil in the ink penetrates into the paper, it can make the ink dry quickly, improve the fixing speed of the ink, and meet the needs of high-speed printing. [0003] Existing printing ink solvent oil mostly belon...
