Abstract

The invention provides a coating coating for high-speed inkjet printing paper and a preparation method thereof. The coating coating adopts the following formula: 70 parts of deionized water, 0.3-35 parts of inorganic filler, 3-10 parts of concentration It is 15-30% ammonia water, 0.1-1 part of foam inhibitor, 5-20 parts of modified polyvinyl alcohol, 0.3-3 parts of cationic additives, 5-15 parts of waterproof emulsion, 6-15 parts of non- Water ethanol, 0.5-2 parts of silane coupling agent, 0.2-0.5 part of defoamer, 0.2-0.5 part of leveling agent. The printing coated paper prepared by using the coating coating for high-speed ink-jet printing paper provided by the present invention solves the problems of poor ink adhesion, slow drying speed, color fading, bleeding and mottled after high-speed ink-jet printing in the prior art , while filling the technical gaps at home and abroad to meet market demand.

Description

technical field [0001] The invention relates to the technical field of coating coatings in the chemical industry and papermaking industry, in particular to a coating coating for high-speed inkjet printing paper and a preparation process thereof. Background technique [0002] With the development of printing technology, the high-speed digital rotary printing machine based on inkjet technology has developed rapidly in the market, and its market demand is huge. The main paper used for rotary printing machine is offset paper and printing coated paper. Among them, Double-offset paper is used for printing middle and low-grade publicity materials and magazines. Printing coated paper, also known as coated paper, is a kind of coated paper for copperplate printing, mainly used for printing high-grade printed matter. The base paper of printing coated paper is made of bleached chemical wood pulp or partially bleached chemical straw pulp on a paper machine. During the printing process, e...
