Abstract

The invention discloses water paint for paper materials and a preparation method thereof, wherein the water paint for the paper materials comprises following components by weight: 45-75% of acrylic copolymer emulsion, 0.4-0.7% of a pH regulator, 0.1-0.5% of a defoaming agent, 0-15% of nano silica dispersion, 0-20% of emulsion paraffin, 0-4% of matting powder, 2-5% of a film forming assistant, 0.1-0.5% of a wetting agent, 0.1-0.5% of a leveling agent, 0.1-0.5% of an antisepsis and sterilization agent, 0.1-1.2% of a thickening agent and 6-16% of deionized water. The water paint has the advantages of easy increase of film thickness, good transparency, smooth surface, good hardness, excellent corrosion resistance, powdering resistance, wear resistance and good printability.

Description

technical field [0001] The invention relates to the field of water paint for paper materials, in particular to a water paint for paper materials and a preparation method thereof. Background technique [0002] Among all kinds of product packaging, paper product packaging accounts for the largest proportion. For example: cartons, cartons, paper bags, paper barrels, honeycomb cardboard, etc., are widely used, easy to recycle and reuse, and meet environmental protection requirements. They are regarded as green packaging and are favored by people. However, the paper packaging material is afraid of moisture and is easy to break, which brings great inconvenience to storage, transportation and use, and the loss is serious. However, if paper coatings are used, these losses may be avoided. Coating a layer of paint on the surface of the paper makes it have the advantages of preventing the penetration of water, water vapor, oxygen and grease, preventing the smell and taste of food fro...
