Abstract
With many years of research, color ink-jet printing technology has reached the requirements of color ink-jet printing. The significance of this experiment is to find a suitable method to improve the quality of color ink-jet printing paper. In this work, the dispersion effect and types of sodium polyacrylate (PAAS) on nano-SiO2 solution are discussed, and the most suitable PAAS dosage is selected. When the dosage of PAAS is 8%, the dispersibility of nano-SiO2 solution is much better, with an average color density of 1.60, a gloss of 59% and an ink absorption value of 10.2 cm. Adhesives also have a great influence on color ink-jet printing paper. When the amount of PVA is 30% of nano-SiO2, the average color density is 1.62. Glossiness and ink absorption are also the best.
Highlights
With the rapid development and popularization of ink-jet printers, scanners and digital cameras, ink-jet printing, as one of the important ways of image and text output, has become more and more popular among customers due to its low price and high quality printing
Ultraviolet spectrophotometer is used to determine the absorbance of suspension under certain wavelength incident light, which was employed to characterize the dispersion of suspension
From the scanning electron microscopy (SEM) of the base paper shown in Fig. 4a, it can be clearly seen that the uncoated base paper fibers interweave with each other and form a three-dimensional network structure
Summary
With the rapid development and popularization of ink-jet printers, scanners and digital cameras, ink-jet printing, as one of the important ways of image and text output, has become more and more popular among customers due to its low price and high quality printing. Inkjet printing paper is a special paper used to print exquisite and high-quality pictures by coating a layer of porous ink-absorbing pigments on the surface of base paper to form a good ink acceptance layer on the surface of paper to meet the requirements of color ink-jet printing[1]. The color ink-jet printing paper is a special processed paper coated This coating can absorb water-based ink quickly, and ensure the non-proliferation of ink[2]. This coating can prevent ink from penetrating too deep and too fast, and can control the diffusion degree and width of ink particles, and separate water-soluble organic dyes from water carriers, leaving pigments on the surface without penetration, reducing capillary phenomena, wrinkling and color migration phenomena, greatly improving printing. Improving the dispersibility of in aqueous solution has become the key to the preparation of nanoSiO2
