WATER-BASED COATING COMPOSITION FOR PAPER AND MANUFACTURING METHOD THEROF

摘要

The present invention relates to a water-based coating composition for paper which protects the surface of a printed matter for a long time by increasing the abrasion resistance of the water-based coating agent for paper when paper containing a printed matter on the surface is coated with the water-based coating agent, exhibits luxurious appearance by making the surface of the printed matter glossy and improves quality of a packing box and the like manufactured by using coated paper, and a manufacturing method thereof. The manufacturing method manufactures the water-based coating agent for paper by using a stirring container in which a stirring operation is consistently performed and comprises: a step (S10) of putting styrene acryl emulsion and water into the stirring container; a step (S20) of mixing an antifoaming agent and a solvent with high boiling point and putting the ingredients into the stirring container; a step (S30) of putting wax into the stirring container; and a step (S40) of putting a surfactant into the stirring container. [Reference numerals] (S10) Put acryl emulsion and water into a stirring container; (S20) Put an antifoaming agent and a solvent with high boiling point by mixing ingredients; (S30) Put wax into the stirring container; (S40) Put a surfactant into the stirring container
