Abstract

The invention relates to the technical field of printing and discloses environment-friendly type water-based oil polish and a preparation method thereof. The environment-friendly type water-based oil polish comprises the following raw materials in percentage by weight: 35-45% of water-based acrylic resin, 20-30% of water-based alkyd resin, 20-30% of acrylic emulsion, 7-15% of an auxiliary solvent, 0.2-1% of a leveling agent, 0.2-1% of a wetting agent, 0.2-1% of a defoaming agent and 0.2-1% of an anti-wear agent. The environment-friendly type water-based oil polish disclosed by the invention is small in solvent on package printing, relatively low in residual quantity of the solvent, good in adhesion, good in viscosity, high in transparency, good in gloss and free of harmful effect on color of presswork, strong in wear resistance, non-toxic and tasteless, high in filming speed, quick to dry, high-temperature-resistant and good in heat sealability. The preparation method of the environment-friendly type water-based oil polish is small in environmental pollution, relatively good in environment-friendly effect, relatively convenient to use, and suitable for follow-up luster finish of printed objects.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to an environment-friendly water-based varnish and a preparation method thereof. Background technique [0002] With the improvement of human awareness of environmental protection, people have paid more and more attention to the factors that affect the change of ecological environment in activities such as production operations and living consumption. In the field of printing, the importance of environmental protection is increasingly recognized by people, and many requirements and constraints in hygiene, environmental protection, labor protection, etc. have been added, especially the requirements for food packaging and printing are more stringent. At present, coating and glazing technology has been adopted by more and more printing manufacturers, which has led to a continuous increase in the demand for varnishes. [0003] Water-based varnish refers to a liquid that uses water as a...
