Water-based paper polishing oil and preparation method thereof

Abstract

The invention provides a water-based paper polishing oil and a preparation method thereof. The water-based paper polishing oil is characterized by comprising the following components in parts by weight: 45-75 parts of styrene-acrylic-organic silicon copolymer emulsion with a core-shell structure, 2-10 parts of water-soluble acrylic resin, 0.5-2 parts of dispersing agent, 0.5-3 parts of wax emulsion, 0.5-2 parts of flatting agent, 0.2-2 parts of defoaming agent, 0-0.5 part of smoothing agent, 0.2-2 parts of neutralizing agent and 5-20 parts of water. The preparation method comprises the following steps: preparing the styrene-acrylic-organic silicon copolymer emulsion with the core-shell structure, preparing a water-soluble acrylic resin solution, and mixing the emulsion and the solution with other raw materials. The water-based paper polishing oil of the invention has the advantages of high polishing performance, high anti-blocking performance and good abrasion resistance.

Description

technical field [0001] The invention relates to a water-based paper varnish and a preparation method thereof, belonging to the technical field of paper glazing coatings. Background technique [0002] Paper glazing is to apply (or spray, print) a layer of paint on the surface of the paper, and form a thin and uniform transparent glossy layer on the surface of the paper after leveling, drying, calendering, and curing. This layer not only makes the surface of the paper bright and smooth, and the color of the picture and text is more vivid, but also plays the role of moisture-proof, anti-fouling, wear-resistant and so on. The most important thing is that this process does not affect the beating and recycling of paper after finishing, and can solve the "secondary pollution" problem caused by the difficulty of beating when recycling paper-plastic coated materials. It is truly green packaging and is being rapidly promoted and applied to Advertisement decoration, book cover, label,...

Problems solved by technology

Therefore, the brightness, wear resistance, and anti-blocking resistance of printed matter are contradictory indicators. To improve the brightness of printed matter, other resistance properties must be sacrificed. The traditional water-based varnish configuration method is very difficult. It is difficult to make the printed matter maintain high gloss and also have excellent resistance to resistance
