Problems solved by technology

[0003] At present, the polyamide resin used in my country's plastic printing ink mainly comes from advanced developed countries such as Japan and the United States. In recent years, with the development of the printing industry and decoration industry in China, relevant scientific research units and enterprises are also making great efforts Develop this kind of resin, but the quality of domestic alcohol-soluble resin still has some shortcomings, such as darker color, poor transparency, serious gel tendency, poor gel recovery, poor solubility and other shortcomings

Embodiment Construction

[0009] 1. Weigh rosin modified alkylphenol phenolic resin 41; tung oil 5; refined linseed oil 7; isophthalic acid alkyd resin 10; high boiling point kerosene 30; myristyl alcohol 2;

[0010] 2. Prepare organoaluminum gelling agent and dilute it with 1:4 linseed oil.

[0011] 3. Preparation method

[0012] Put the weighed and measured rosin modified alkylphenol phenolic resin, tung oil, and refined linseed oil into the enamel reaction kettle in sequence, heat to 180°C to melt the resin, start stirring, keep it warm for 1 hour when the temperature rises to 250°C, and add Phthalic acid alkyd resin, stirring, at a temperature of 220 ° C, keep warm for 30 minutes, then add high boiling point kerosene (reserved 5%) and myristyl alcohol, when the temperature is lowered to 160 ° C, use 1:4 diluted organic Aluminum gelling agent, heat up to 170°C-180°C and keep it warm for 30 minutes, then use the reserved high-boiling point kerosene to adjust the viscosity to 12000-16000mPa.S / 25°C, f...

Abstract

The invention relates to a connecting material for low-viscosity high-brightness quick drying ink and a preparation method thereof. The invention is characterized in that the connecting material for low-viscosity high-brightness quick drying ink is mainly prepared from rosin improved alkyl phenol formaldehyde resin, tung oil, refined linseed oil, m-phthalic acid alkyd resin, high-boiling-point kerosene, tetradecyl alcohol, organic aluminum gelling agent and the like. The connecting material for low-viscosity high-brightness quick drying ink has the characteristics of high ink setting speed, quick drying, bright film layer and the like.

Description

technical field [0001] The invention relates to a low-viscosity, high-brightness, fast-drying ink binder and a preparation method thereof, belonging to the field of offset printing. Background technique [0002] With the development of printing, plastic packaging and decoration culture, high-grade special plastic printing inks have developed rapidly. It is an indispensable printing ink for packaging materials such as ethylene and polypropylene films. The ink prepared with this kind of binder has good gloss and adhesion performance, excellent alcohol dilution, low gelling property, quick drying and low odor. [0003] At present, the polyamide resin used in my country's plastic printing ink mainly comes from advanced developed countries such as Japan and the United States. In recent years, with the development of the printing industry and decoration industry in China, relevant scientific research units and enterprises are also making great efforts The development of such resin...
