Abstract

The invention discloses a multifunctional membrane coating liquid suitable for ink-jet and laser printing, and a preparation method thereof. The preparation method comprises following steps: firstly,isophorone diisocyanate and a polycarbonate diol are subjected to polymerization, an appropriate amount of a hydroxyl acrylate is added, chain propagation, neutralization, and emulsification are carried out so as to obtain a primarily modified aqueous polyurethane; polyvinyl alcohol solutions with different functions are prepared, and a mixed dispersion solution of silica and alumina is prepared,and at last, mixing with auxiliary agents such as a wetting agent, an anti-foaming agent, a thickening agent, and an antistatic agent is carried out so as to obtain the multifunctional membrane coating liquid suitable for ink-jet and laser printing. The preparation method is low in preparation cost and excellent in printing effect; the production technology is simple; the multifunctional membranecoating liquid is convenient for coating; the solid content is as high as 35%; the multifunctional membrane coating liquid is suitable for coating of a plurality of polyester or polyolefin membranes such as PET, PVC, and PETG membranes, and can be used for production of coated products with different functions.

Description

technical field [0001] The invention relates to a multifunctional diaphragm coating solution suitable for inkjet and laser printing and a preparation method thereof, belonging to the technical field of polymer materials. Background technique [0002] The rapid development of computer technology, digital imaging technology, and the popularization of computers have made various digital printing and digital printing technologies continue to improve. Compared with digital printing, digital printing is more flexible and more personalized. The advancement of science and technology and the development of the economy have promoted the innovation of emerging materials, especially functional polymer materials. By coating the surface of ordinary plastic diaphragms, the diaphragms are endowed with various specific functions. [0003] There are two most commonly used digital printing technologies. Among them, inkjet printing has higher resolution and clearer printed images, but its disa...
