Problems solved by technology

[0009] However, these processing methods are relatively complicated in technology, and it is not easy to control the degree of reaction, and the requirements for operators and machinery and equipment are relatively high.
In addition, the plastic surface treated by the conventional electric spark method and flame method is prone to deactivation, and the treated plastic products must be printed immediately, otherwise they may still fail, and the printing effect will not be good.

Abstract

The invention belongs to the field of printing machining and particularly relates to a method for improving ink adhesion in a plastic printing product. The method includes the following steps of (1) pretreatment of the plastic product and (2) printing. An ion sputtering method is adopted to conduct oxidation treatment on the surface of the plastic product, energy can be rapidly transferred to a special functional group on the plastic surface, and purposes of even heating and even oxidization are achieved; printing ink is prepared in the manner that based on ordinary ink, microcrystalline wax, N, N-dimethylaniline, lignin-based epoxy resin and a surface active agent are added, and consistency and permeability of the ink and the plastic product are increased. The plastic printing product prepared through the method has the advantages that adhesion between the plastic product and the ink is high, and friction resistance is achieved.

Description

[0001] 【Technical field】 [0002] The invention belongs to the field of printing processing, in particular to a method for improving ink adhesion in plastic printed matter. [0003] 【Background technique】 [0004] Plastic is a high molecular compound polymerized by addition polymerization or polycondensation reaction with monomer as raw material. It is commonly known as plastic or resin. It can freely change its composition and shape. , Colorants and other additives. Most plastics are light in weight, chemically stable, will not rust, have good impact resistance, have good transparency and wear resistance, good insulation, low thermal conductivity, and have a wide range of applications. [0005] In order to further expand the application of plastics in various industries in life, it is necessary to print plastic products. The printing substrate has different surfaces, and the paper material has a structure of numerous fibrous capillary pores. These non-specially treated paper...
