Abstract
The invention relates to a preparation method of a PET matrix coating suitable for ink-jet printing, which comprises the following steps: coating a layer of 1-2 um PET prime coat coating liquid (914) on a 50-ply white PET corona surface by using a coating machine anilox roller, and then coating a layer of coating liquid (waterborne polyurethane 937 and an ink absorber) of 15-18 um by using the coating machine anilox roller. The invention can effectively improve the ink absorption performance and the color reduction degree of the ink absorption coating.
Description
Technical Field
The invention relates to the technical field of coatings, in particular to a preparation method of a PET matrix coating suitable for ink-jet printing.
Background
In recent years, the ink jet printing technology and the related ink jet printer have higher printing speed and higher printing quality compared with the traditional printing, and the factors influencing the ink jet printing quality are related to the ink-attracting ink absorption performance of the bearing material besides the quality of the used ink jet printer and ink, and in order to improve the ink-attracting ink absorption performance of the bearing material, an ink-absorbing coating is often prepared on the surface of the bearing material.
The invention changes the process by adding the base coat, thereby influencing the absorption and color reduction of the printing ink, effectively improving the adhesive force of the ink absorption coating, thereby improving the ink absorption performance and the color reduction degree, and being suitable for the printing and packaging fields of building material industry, furniture industry, craft gift industry, advertisement decoration industry, digital shell industry and the like.
Disclosure of Invention
