Abstract

The invention discloses a novel method for coating microcapsules, and particularly relates to a method for realizing coating for microcapsules by film transfer. The method disclosed by the invention comprises the following steps of: a, running coating rolls and achieving a running speed, when the tail of paper is led through a coating machine, turning on full-width spraying water, driving an acting combined beam by a cylinder, rotating a metering rod, pressurizing by a loading air pocket, and charging a microcapsule coating by a charge tube; b, when a loading pressure is stable and coating layers on the surfaces of the rolls are uniform, and turning on edge-spraying water; and c, after paper is spread with a full width on the coating machine, bonding the two coating rolls, turning on the full-width spraying water to an automatic position, and adjusting a coating weight according to a coating weight horizontal curve, and via the adjustment of a fine adjustment mechanism and the pressurization of the loading air pocket. The method disclosed by the invention has the advantages that control on the coating weight is stable; the coating weight is convenient and fast to adjust by the fine adjustment mechanism; and a coating solid content is high, so that a requirement on the drying capacity after coating is low, thus reducing steam consumption, and the production cost of per ton of paper.

Description

technical field

[0001] The invention introduces a new method for coating microcapsules, in particular relates to a method for coating microcapsules by film transfer. Background technique

[0002] Coupled carbonless copy paper can be divided into: upper paper (CB paper), that is, the back of the paper is coated with a paint containing a color-developing agent; middle paper (CFB paper), that is, the front of the paper is coated with a paint that contains a color The coating of the color agent; the lower paper (CF paper) is coated with the coating containing the color developer on the front side of the paper. The color development mechanism of carbon-free copy paper is: when the good carbon-free copy paper is subjected to external pressure, the microcapsules coated on the bottom of the upper layer of paper are broken. , the colorless dye liquid in the microcapsules flows out and contacts the color developer on the front of the next layer of paper, reacts and develops color, an...
