Problems solved by technology

However, silicon-based products have the disadvantages of high coating brittleness, low color density, and low image weather resistance, while aluminum-based products need to use special alumina powder, which greatly increases production costs, but it overcomes the above shortcomings of silicon-based products. It can print images with high quality and high weather resistance, and its performance is the product with the image quality closest to traditional silver salt photos in inkjet consumables

Embodiment Construction

[0019] In order to facilitate the understanding of those skilled in the art, the present invention will be described in further detail below in conjunction with specific embodiments:

[0020] This embodiment discloses a kind of aluminum oxide ink-jet coating, which can be coated on the paper base to form an ink-jet coating. According to the weight ratio, the coating composition is: 20 parts of alumina powder, 76.3 parts of water, 0.3 part of hydrochloric acid, poly 1.8 parts of vinyl alcohol, 0.14 parts of crosslinking agent, 1.45 parts of cationic color fixing agent, and 0.06 parts of surfactant.

[0021] Wherein, the aluminum oxide powder is a nanoscale micropowder with a particle size between 15 and 35 nanometers. By adding hydrochloric acid as the dispersant of nano-scale alumina, the printing color has high color saturation while the dispersion system has good stability; polyvinyl alcohol (can be purchased from KURARAY (Kuraray) company in Japan, its model PVA235) is use...

Abstract

The invention relates to an alumina ink-jet coating and a manufacturing method thereof. The coating comprises the following components of 19 to 21 weight ratios of nanometer alumina powders, 75.3 to 77.3 weight ratios of water, 0.22 to 0.28 weight ratios of hydrochloric acid, 1.6 to 2.0 weight ratios of polyvinyl alcohol, 0.12 to 0.16 weight ratios of cross linker, 1.40 to 1.50 weight ratios of cationic coloring stabilizer and 0.04 to 0.08 weight ratio of surface active agent. The manufacturing method includes the following steps of adding the hydrochloric acid into the water to stir evenly, adding the alumina powders to stir until the powders are dispersed uniformly, cutting for 8 to 12 minutes, pumping into a vacuum pan to stir and cool, filtering with a filter screen which has 350 to 450 meshes, standing for 2 to 3 hours to eliminate bubbles. The invention provides a high-quality formula of an ink-jet printing coating. The formed printed coating is very high in surface flatness and the high-light property is fully shown. As for printing shade patterns, the invention can display very good layering, high vividness, image stability and clarity.

Description

technical field [0001] The invention relates to an aluminum oxide ink-jet paint and a preparation method thereof. Background technique [0002] At present, the domestic market is mainly dominated by swelling type photo paper. Although the production cost of swelling type photo paper is low, it has poor ink absorption performance, slow drying, and is not waterproof. High, and the printing quality is far from the traditional silver halide photo, it can only be used as a low-grade product. At present, the technical level of domestic manufacturers of inkjet printing materials is very close, and their high-gloss photo paper products are basically of this type. [0003] The highest-grade high-gloss photo paper sold in the domestic market is basically imported from Japan and other countries, and some of them are "original" products from printer manufacturers. Larger quantities, although they are labeled with domestic brands, are all imported photo paper cut and packaged. This typ...
