Abstract

The invention provides an inkjet printing thickener and a method for preparing the same. The method for preparing the inkjet printing thickener comprises the following steps: mixing aqueous ammonia with an acrylic monomer until the pH value of the mixture is 6.5-7, adding a cross-linking agent, stirring and mixing to prepare a water phase; mixing an emulsifier with an organic solvent to prepare an oil phase; adding and stirring the water phase to the oil phase, dropwise adding aqueous initiator solution, polymerizing for 1-4 hours at 50-80 DEG C, reducing temperature, discharging, adding a phase transfer agent, and stirring fully and uniformly to obtain the finished product. The inkjet printing thickener provided by the invention has high solid content, moderate viscosity and strong electrolyte resistance and can be used by adopting a padding process during pre-treatment for inkjet printing to ensure that the printed patterns have clear outlines, deep color and no infiltration.

Description

technical field [0001] The invention relates to the printing and dyeing industry, in particular to an inkjet printing thickener used in an inkjet printing process and a preparation method thereof. Background technique [0002] Inkjet printing technology is a brand-new printing method. It abandons the complex link of plate making in traditional printing, and directly sprays printing on fabrics, which improves the printing accuracy and realizes small-batch, multi-variety, multi-color printing. Traditional printing has problems such as large area and serious pollution. At the same time, inkjet printing has won the favor of more and more consumers with its flexible flower back size and realistic printing effect. [0003] In fact, there is only a very small amount of ink that can be sprayed on the fabric by jetting technology, and due to strict dye purity requirements and continuous jetting requirements for the conductivity of the ink, other printing auxiliaries used cannot be a...
