Abstract

The invention discloses a modified rosin resin for an aqueous ink thickener and a preparation method thereof. The method comprises: heating rosin to completely melt into a liquid; adding maleic anhydride, wherein maleic anhydride accounting for 8-12% of the total amount is added in one time, the remaining maleic anhydride is divided into five parts, and the five parts are added every 20 min; adding a long-chain polyol, wherein the long-chain polyol is divided into ten equal parts, and the ten parts are added every 15 min; reducing the temperature inside the reaction kettle to 140+ / -5 DEG C, adding a measured amount of an alkali, and continuously stirring for half an hour; and reducing the temperature inside the reaction kettle to 100+ / -5 DEG C, adding a measured amount of water, stirring for half an hour, cooling to a room temperature, and discharging the material. According to the present invention, the preparation is simple, the quality is reliable, and the modified rosin resin is widely used in a variety of water-based ink thickener modified rosin resins and the preparation method thereof.

Description

technical field

[0001] The invention belongs to the technical field of polymer synthesis, and relates to a modified rosin resin used as a water-based ink thickener and a preparation method thereof. Background technique

[0002] Thickener is an indispensable auxiliary agent in the preparation process of water-based ink. On the one hand, adding a thickener can improve the physical and chemical stability of the water-based ink; on the other hand, adding a thickener can improve the stability of the toner and filler in the water-based ink, ensuring the storage stability of the water-based ink.

[0003] The water-based ink thickeners in the prior art mainly include: inorganic thickeners, organic thickeners and synthetic polymer thickeners. The thickening effect of inorganic thickeners is obvious, but during the printing process, the shear force generated by the continuous rotation of the printing roller will reduce the viscosity of the water-based ink during printing and affect t...
