Embodiment Construction

[0034] The invention provides a kind of production method of ink additive, comprises the following steps:

[0035] The light oil is subjected to hydroisomerization and hydrofining in sequence, and the refined product obtained is subjected to high-pressure gas-liquid separation and low-pressure gas-liquid separation to obtain low-fraction oil, and then the obtained low-fraction oil product is subjected to atmospheric pressure fractionation, reduction Pressure fractionation and stripping to obtain ink additives;

[0036] The temperature of the hydroisomerization is 330-340°C, and the temperature of the hydrofining is 240-250°C;

[0037] The pressure of the high-pressure gas-liquid separation is 14-15MPa;

[0038] The temperature of the atmospheric fractionation is 285-290°C, and the pressure of the atmospheric fractionation is 230-240KPa; the temperature of the vacuum fractionation is 350-360°C, and the pressure of the vacuum fractionation is 4-5KPa.

[0039] In the present in...

Abstract

The invention provides a production method for a printing ink additive. The method comprises the following steps that hydrogenation isomerism and hydrogenation refining are performed on light slide oil in sequence, the obtained refined product is subjected to high-pressure gas-liquid separation and low-pressure gas-liquid separation, low-component oil is obtained, and then the obtained low-component oil product is sequentially subjected to normal pressure fractionation, low-pressure fractionation and steam stripping to obtain the printing ink additive; the temperature of hydrogenation isomerism is 330-340 DEG C, the temperature of hydrogenation refining is 240-250 DEG C; the pressure of high-pressure gas-liquid separation is 14-15 MPa; the temperature of normal-pressure fractionation is 285-290 DEG C; the pressure of normal pressure fractionation is 230-240 KPa; the temperature of decompression fractionation is 350-360 DEG C, and the pressure of decompression fractionation is 4-5 KPa. The printing ink additive is stable in performance, free of environment contamination, free of damage to the human body and high in distillation recycling rate. The invention further provides a production device for the printing ink additive.

Description

technical field [0001] The invention belongs to the field of petrochemical technology, and in particular relates to a production method and a production device of an ink additive. Background technique [0002] Ink additives are important materials for printing, which express patterns and characters on substrates through printing. The ink includes main components and auxiliary components, which are uniformly mixed and rolled repeatedly to form a viscous colloidal fluid. It is composed of linking material (resin), pigment, filler, auxiliary agent and solvent, etc. It is used for various printing of books, magazines, packaging and decoration, architectural decoration and electronic circuit boards. With the increase of social demand, the variety and output of ink have also expanded and increased accordingly. [0003] In recent years, people have paid more and more attention to environmental protection and occupational health of employees, as well as to the safety performance ...
