A kind of coated printing medium and preparation method thereof

Abstract

The invention discloses a coated printing medium, which is evenly coated on a substrate, and is characterized in that: the coated printing medium consists of 100 parts of water, 8 to 12 parts of di Silicon oxide, 6-10 parts of titanium dioxide, 50-100 parts of PM-2 acrylic synthetic rubber, 50 parts of 676 synthetic rubber, 1.4-2.2 parts of dispersing aid, 0.5 part of defoaming aid, 0.3? Composed of 0.5 parts of leveling aid and 5 parts of crosslinking agent. Compared with the traditional printing medium, the coated printing medium of the present invention can greatly improve the ink adhesion in the ink printing process, increase the printing color density, and greatly improve the scratch resistance of printed products.

Description

technical field [0001] The invention relates to a coated printing medium and a preparation method thereof, which is suitable for letterpress printing, gravure printing, offset printing, screen printing and inkjet printing, and is suitable for producing various color printing label paper and various color printing Packaging Materials. Background technique [0002] Synthetic material is a new type of material that is widely used. Taking PP paper as an example, PP synthetic paper is made of resin such as polyolefin and inorganic filler as the main raw materials, processed through extrusion process, and has the characteristics of plastic and paper at the same time. Multifunctional material is a new type of plastic material product, and it is also an environmentally friendly product. It has the characteristics of light specific gravity, high strength, tear resistance, good printability, shading, anti-ultraviolet, durable, economical and environmentally friendly.

AI Technical Summary

Problems solved by technology

However, due to the inherent characteristics of PP synthetic paper and PET film materials, the surface energy of the material is low, and the printing ink is not easy to adhere. After printing, the ink has poor adhesion and low color density, which greatly affects the actual application effect.

[0004] The traditional treatment method is to add corona treatment in the front section of printing. The -OH and -COOH generated on the surface after corona will bridge the ink. The initial effect is very good, but the surface tension will decay rapidly after corona treatment. Taking PET film as an example, the effect after the initial corona treatment can last for about 7 days at most; due to the unstable and easily weakened corona treatment effect, the long-term fastness of the printed ink layer is not strong, and it is easy to scratch. Therefore, it is necessary to solve the problems of poor ink adhesion, low color density and poor scratch resistance in traditional uncoated printing materials.
