Abstract
The invention discloses a waterproofing ink-jet printing media and preparation method thereof. The waterproofing ink-jet printing media disclosed in the invention comprises a sheet waterproof substrate, wherein, one side of the sheet waterproof substrate is coated with a coating liquid to form an ink-absorbing waterproof layer, the coating liquid is prepared by dissolving the following ingredients in purified water: 10-40 weight portions of silicon dioxide or aluminium hydroxide, 2-5 weight portions of polyvinyl alcohol and 20-60 weight portions of cationic acrylic acid. The preparation method disclosed in the invention comprises a step of preparing the coating liquid and a step of coating the coating liquid on the sheet waterproof substrate. According to the invention, after printing, the cationic acrylic acid in the ink-absorbing waterproof layer reacts with the anionic ink to form water-insoluble precipitates, so that the waterproof effect can be realized. The waterproofing ink-jet printing media can bear rain, can be used in outdoor environments, and is convenient for preservation.
Description
Technical field
The present invention relates to the ink-jet printing media technical field, specifically, relate to a kind of waterproofing ink-jet printing media and preparation method thereof.
Background technology
The ink that inkjet printing is used is divided into two big systems, and a kind of is water-soluble type of dye ink, and another kind is that pigment solids is scattered in the central water-fast pigment ink of water-based system, and these two kinds of inks all are reinforcing yin essence ionic inks.The preparation of traditional ink-jet printing media is normally: apply the ink absorbing layer that contains polyvinyl alcohol or methylcellulose on base material, polyvinyl alcohol or methylcellulose are as film forming agent and thickener, and its blotting principle is the swelling blotting.But can not waterproof after traditional ink-jet printing media is printed, print media can not wiping after inkjet printing is intact, overflows with regard to having a large amount of inks after running into water, has a strong impact on printing effect at once; Drench with rain because of not bearing, be difficult to use in the open air, also be difficult to preserve.
In order to address this problem, the measure of taking usually is: after the inkjet printing, manually enclose one deck waterproof membrane again on medium, to reach the waterproof purpose.But adopt this mode can increase coating processes one, increase cost of labor, prolong preparation process, reduce production efficiency.
Based on above present situation, it is extremely urgent to produce the finish ink-jet printing media that promptly directly has water-proof function of a kind of printing.
