Abstract

The invention relates to matt color ink jet printer paper paint and a preparation method thereof. The preparation method is characterized in that the method comprises the following steps: adding dispersant into deionized water to be dissolved at the room temperature; adding modified bentonitic clay to the dissolved deionized water and dispersing at the room temperature; adding silicon dioxide to the modified bentonitic clay dispersion liquid for dispersion, and obtaining mixed dispersion liquid; adding an adhesion agent to the mixed dispersion liquid while stirring; adding a silicone antifoaming agent, PDMDAAC and carboxymenthyl cellulose in sequence, and obtaining paint liquid after evenly blending and stirring. Because the modified bentonitic clay is utilized as the pigment to prepare the paint for the matt color ink jet printer paper, good water absorption performance, good color fixation performance, high color density, good color reductibility and no infiltration of the matt color ink jet printer paper can be ensured, and the purpose of reducing the cost of the matt color ink jet printer paper can be achieved.

Description

technical field [0001] The invention relates to a matte color ink-jet printing paper coating and a preparation method thereof, in particular coating the coating on the color ink-jet printing paper. Background technique [0002] Color inkjet printing paper is a coated processed paper. In recent years, with the rapid development of digital technology, digital imaging technology has been rapidly improved. Due to its low cost and high image quality, inkjet printing is widely used in many fields such as advertising, office and home, and has become the main way of digital imaging. Due to the continuous innovation of inkjet printing equipment, the quality of inkjet printing has undergone a qualitative leap, which is close to the quality level of traditional photos. Compared with the replacement speed of inkjet equipment, the development of inkjet printing paper lags behind seriously. Especially in my country, the development of high-quality inkjet paper coating technology is stil...
