Making technique of colored coating paper

Abstract

The invention discloses a making technique of colored coating paper, comprising the following steps of: (1) providing base paper; (2) selecting corresponding water-soluble coating according to the performance requirement of a product; (3) selecting water-soluble colored dye according to coloring requirement, and determining the addition of the colored dye according to color intensity; (4) mixing and stirring the coating and the colored dye so as to obtain composite coating; and (5) coating the mixed composite coating to the surface of the base paper with a coating machine so as to obtain coating paper. According to the making technique of colored coating paper provided by the invention, the water-soluble colored dye is added to the water soluble coating for coating the base paper, and coating paper with different colors is made by adding different colored dye, so that the making technique of colored paper for printing, which replaces the traditional paper making, is simple in processing steps and low in production cost, and simultaneously workers are prevented from being poisoned by contact of poisonous gas such as methanol when working, the personnel safety of the workers is ensured, and the pollution to the environment is reduced.

Description

technical field [0001] The invention relates to a manufacturing process of coated paper. Background technique [0002] Due to its good visual effect, colored paper is widely used in office, publicity, packaging and books, and its role in life is becoming more and more extensive. At present, the production of traditional colored paper is generally to print directly after the paper is made, but it has the following problems: On the one hand, the working environment of the printing factory is harsh, and there are toxic volatile gases such as methanol, which may easily cause poisoning of printing workers and harm the human body It is extremely large, and it pollutes the surrounding environment greatly; on the other hand, the cost of color printing is high, and the production cost is high. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the invention provides an environmentally friendly and low production cost colored coated paper man...
