A kind of synthetic paper printing material and preparation method

Abstract

A synthetic paper printing material and a preparing method thereof are disclosed. The top surface of PP synthetic paper is provided with a printing coating. The coating formula of the printing coating includes a modified waterborne chlorinated polypropylene emulsion. Raw materials of the modified waterborne chlorinated polypropylene emulsion include, by weight, 20-30 parts of ethyl acetate, 30-40 parts of butanone, 30-40 parts of chlorinated polypropylene, 0.4-0.6 part of benzoyl peroxide, 6 parts of methacrylic acid, 3 parts of butyl acrylate, 3 parts of maleic anhydride, 20-30 parts of an aqueous dimethylaminoethanol solution having a concentration of 15%, 50 parts of deionized water, 2 parts of a nonionic emulsifier that is polyoxyethylene cetyl ether and 1 part of an ionic emulsifier that is sodium lauryl benzene sulfonate. The coating has extremely good high-temperature adhesion, weather resistance and low-temperature flexibility, and can be used perfectly in match with an HP Indigo colorful digital transfer printing technique. Application and popularization of the printing material have good economic benefit and social benefit.

Description

Technical field [0001] The invention belongs to the field of digital printing technology and imaging, and relates to a PP synthetic paper printing material and a preparation method, in particular to a PP synthetic paper that has been specially coated and applied to the output of HP Indigo color digital transfer technology. printing material. Background technique [0002] HP Indigo color digital transfer technology is an environmentally friendly and efficient printing technology that has just emerged. The HPIndigo series of digital printing presses rely on its color digital printing technology and process, while providing the industry's best printing quality, wide color gamut, diversity of carrier materials, high speed, high efficiency and flexibility, and can variably print each printed copy. Hundreds of different pictures can be printed in one typesetting. HP Indigo printing has excellent image processing functions and ink coverage flexibility, comparable to or even surpassing...

AI Technical Summary

Problems solved by technology

The adhesion fastness of many primers is also not up to standard. After the pressurization and heating process of Indigo printing, the coating surface is often damaged by the blanket and sticks to the blanket.

This pollutes the blanket very seriously, and it will cause the blanket to be scrapped over time

In contrast, although solvent-based coatings such as epoxy resins, alkyd resins, and vinyl acetate resins have acceptable adhesion fastness to PP synthetic paper substrates; however, due to the strong polarity of these resins, they are not compatible with the amphiphilic polymers in ElectroInk. The properties are too different. After printing tests, it is found that ElectroInk cannot be printed on the surface of the above three resin coatings, and the ink layer has no peeling force.
