Description
Technical Field
The invention belongs to the technical field of printing ink, and relates to water-based scratch-resistant matte oil and a preparation method thereof.
Background
Gloss oil is used as a printing surface treatment printing material and widely applied to the printing industry, and a solid film layer with certain strength and smooth surface is formed by coating the gloss oil on the surface of an object, so that the effect of protecting printed pictures and texts can be well achieved, and therefore the gloss oil is widely printed on the surfaces of food, beverage, shoes, clothes, cigarette and wine packaging boxes.
With the development of printing industry and the attention of people on environmental protection, the development of water-based matte gloss oil is more and more emphasized by people. The environment-friendly matte wear-resistant gloss oil is more and more favored by people due to the characteristics of no toxicity, no harm and environment friendliness, and becomes the dominant force for paper glazing. The paper glazing requires high wear resistance, good adhesion and good blocking resistance, but the environment-friendly matte wear-resistant gloss oil sold in the market at present hardly meets all the performances, and the conventional means is mainly adopted for solving the problems, such as adding a large amount of additives such as matte powder and wax slurry into acrylic emulsion. The matte gloss oil is not stable enough, and the matte powder is easy to layer in an acrylic acid solution, so that in order to meet the matte requirement of a printing product, the matte powder needs to be dispersed when the matte oil is prepared, the preparation process of the matte gloss oil is complex, the scratch resistance of the prepared matte gloss oil is not enough, and the application range of the prepared matte gloss oil is narrow.
