Abstract

The invention discloses a preparation method of gloss oil finishing emulsion, and belongs to the technical field of finishing emulsion preparation. The preparation method comprises the following steps: S1, pre-emulsifying, adding the deionized water, a K12 emulsifier and a PCA-039 emulsifier into a pre-emulsification cylinder, stirring and mixing for 15 minutes, sequentially adding styrene, butyl acrylate, hydroxyethyl methylacrylate, acrylic acid, acrylamide and DBP plasticizer, emulsifying and stirring for 30 minutes to obtain a pre-emulsion for later use. The gloss oil finishing emulsion provided in the invention is relatively high in solid content, compared with the prior art, the gloss oil finishing emulsion has the advantages of higher wear resistance, better set-off prevention effect, clear appearance of a wet film for a long time, no yellowing in long-time use, favorable water resistance, favorable scrubbing resistance and favorable market prospects.

Description

technical field [0001] The invention belongs to the technical field of varnish emulsion preparation, and relates to a preparation method of varnish varnish emulsion. Background technique [0002] Varnish is a coating applied to the surface of an item to increase gloss and protect the inner layer. A resin with good film-forming properties is dissolved in a solvent (medium) to make a transparent and bright material with certain fluidity and viscosity. A layer of coating that improves the aesthetics and other properties of an article. [0003] At present, the varnishes on the market have poor wear resistance for the printing surface, and the overall clarity is insufficient. During long-term use, problems such as wear and yellowing are prone to occur, and the service life is short. Contents of the invention [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] A kind of preparation method of varnish varnish e...
