Aqueous gold powder gloss oil and preparation method thereof

Abstract

The invention relates to aqueous gold powder gloss oil and a preparation method thereof. The method comprises the following steps of: preparing a directional alignment agent: prefabricating 0.3-0.7 part by mass of synthetic sheet silicate into a 10% aqueous solution for later use. Preparing an aqueous gloss oil emulsion: mixing and stirring 50-70 parts by mass of an aqueous polyacrylate dispersionand 0.3-0.7 part by mass of polyether modified organosiloxane. Preparing an additive: diluting 0.4-0.8 part by mass of a benzotriazole solution and 0.2-0.6 part by mass of fatty acid ester with equalmass of water, and mixing and stirring the diluted benzotriazole solution and the fatty acid ester. Adding the additive: adding the additive into the aqueous gloss oil emulsion by stirring at a low speed. Adding an the directional alignment agent: adding the directional alignment agent into the additive-containing aqueous gloss oil emulsion, and mixing, stirring and adding 30-35 parts by mass ofdeionized water.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a water-based gold powder varnish and a preparation method thereof. Background technique [0002] Water-based glazing oil, also known as dispersion-type glazing agent, has excellent characteristics such as low cost, wide source of materials, good gloss, good wear resistance and corrosion resistance, and is widely used in food packaging, interior decoration, machinery manufacturing, etc. fields. Water-based varnish can not only increase the value of printed products, but also increase the heat-proof and moisture-proof performance of the ink, which can protect the imprint and improve the service life of the printed matter. In order to increase the color of water-based varnish prints, copper and gold powder are often added to the water-based varnish to improve the metallic texture of the printed products. [0003] The traditional varnish used to prepare copper and gold powder generally use...

AI Technical Summary

Problems solved by technology

However, on the one hand, nitro varnish or phenolic varnish has flammable characteristics, and there are potential safety hazards in the process of manufacturing or using

On the other hand, nitro varnish or phenolic varnish will produce VOC (volatile organic compounds, volatile organic compounds) during use, which is not only harmful to human health but also has a bad impact on the production and use environment

Secondly, copper gold powder is a kind of metal powder with small particles, which is easy to oxidize and blacken in the water-based system and affect its metallic luster.
