Problems solved by technology

However, the ink painted on the surface of the impregnated paper is prone to change with the long-term use of the impregnated paper, especially if the impregnated paper is placed indoors where it is easily exposed to the sun or in an outdoor environment exposed to wind and sun. The situation of yellowing and whitening makes the graphic ink layer on the surface of the impregnated paper lose its original luster
[0003] At present, the light fastness level of general inks can only reach 4-5 levels, and the main light fastness of inks is pigments, and the main components of general pigments are metal oxides or light fast pigments; The level method is to increase the coloring power of the pigment, thereby increasing its metal oxide content, but the greater the metal oxide content, the greater the weight of the ink, which is not conducive to the printing of ink on impregnated paper

Abstract

The invention relates to the technical field of printing ink, in particular to high-sun-resistance printing ink for impregnated paper and a preparation method of the high-sun-resistance printing ink.The high-sun-resistance printing ink for the impregnated paper is prepared from the following raw materials in parts by weight: 40-60 parts of a urethane acrylate emulsion, 8-10 parts of mixed monomer, 2-3 parts of a sun-resistant agent, 2-3 parts of photoinitiator, 5-6 parts of inorganic filler, 1-3 parts of a wax additive and 20-25 parts of a solvent. The high-sun-resistance printing ink for theimpregnated paper is good in adhesive force and can be stably attached to the surface of the impregnated paper, and an ink layer formed after painting is sun-resistant, not prone to yellowing and aging and good in stability. The adopted urethane acrylate emulsion contains an acrylic functional group and a polyurethane component, is good in adhesion, can be stably attached to the stable surface ofimpregnated paper, and is fast to cure, and meanwhile, the contained polyurethane component can enable the ink to have relatively good flexibility and peel strength after being cured.

Description

technical field [0001] The invention relates to the technical field of printing inks, in particular to a high-light fast printing ink for impregnated paper and a preparation method thereof. Background technique [0002] The impregnated paper is made of non-woven wood pulp mixed with PE and plant fiber. It has super absorption and resistance to dissolution. The ink is easy to print on the surface of the impregnated paper. However, the ink painted on the surface of the impregnated paper is prone to change with the long-term use of the impregnated paper, especially if the impregnated paper is placed indoors where it is easily exposed to the sun or in an outdoor environment exposed to wind and sun. In the case of yellowing and whitening, the graphic ink layer on the surface of the impregnated paper loses its original luster. [0003] At present, the light fastness level of general inks can only reach 4-5 levels, and the main light fastness of inks is pigments, and the main comp...
