Problems solved by technology

In order to completely cover the background color of the substrate, there are two conventional treatment methods as follows. One is to directly apply a layer of opaque paint on the surface of the substrate to completely cover the background color of the substrate. Color will affect; the second method is to directly coat a layer of dark coating on the decorative base paper to improve the covering ability of the base paper, but this method will destroy the air permeability, pH paper, permeability and other indicators of the base paper itself. Printing also affects

Abstract

The invention discloses an anti-penetrating water-based ink used for decorative paper. The anti-penetrating water-based ink is composed of, by weight, 45 to 55% of titanium dioxide, 15 to 20% of casein resin, 0.5 to 3% of a dispersant, 4 to 6% of propylene glycol, and the balance deionized water. The invention also discloses a preparation method of the anti-penetrating water-based ink used for decorative paper. The preparation method comprises following steps: (1) deionized water and propylene glycol are delivered into a dispersing kettle, casein resin and the dispersant are added, an obtained mixture is stirred to be uniform, titanium dioxide is added, and a water-based ink is obtained via stirring dispersion using a dispersion machine; (2) the obtained water-based ink obtained via stirring dispersion is delivered into a bead mill for grinding; and (3) after grinding, the water-based ink is filtered so as to obtain the water-based ink finished product. The anti-penetrating water-based ink used for decorative paper is capable of improving penetrating resistance of low gram weight decorative body paper to be as excellent as that of high gram weight decorative body paper, and solving a problem that press penetrating of high gram weight light color decorative paper is easily caused.

Description

technical field [0001] The invention relates to a water-based ink and a manufacturing process thereof, in particular to a bottom-proof water-based ink for decorative paper and a manufacturing process thereof. Background technique [0002] The current shortage of global forest resources has prompted businesses to pay attention to the research and development of wood substitutes. Artificial wooden floors and artificial furniture panels have become important substitutes for wood. The products meet the needs of green, low carbon, energy saving and environmental protection. They are important decoration materials with high cost performance. Artificial wooden floors and artificial furniture panels are made of decorative paper and artificial The decorative paper is used as the decorative paper for artificial wood floors and artificial furniture panels. Decorative paper is widely used and its proportion is increasing year by year. In order to adapt to the increasingly fierce market...
