Environmentally-friendly water-based coating for ensuring printing smoothness of cigarette packing paper, and production technology thereof

Abstract

The invention discloses an environmentally-friendly water-based coating for ensuring the printing smoothness of cigarette packing paper, and a production technology thereof. The coating comprises 5-10parts of deionized water, 3-5 parts of edible alcohol, 30-40 parts of a styrene copolymer, 40-60 parts of acrylic resin and 1-5 parts of an assistant. The production technology comprises the following steps: mixing the deionized water and edible alcohol in a dispersing kettle, then adding a defoaming aid, and performing mixing and dispersing to obtain a cosolvent mixture for later use; taking andmixing the acrylic resin, the styrene copolymer and a high density polyethylene wax dispersant aid in the dispersing kettle, then adding a dipropylene glycol monomethyl ether film forming aid, and continuously performing dispersing; and slowly filtering and adding the prepared solvent mixture, performing dispersing until the obtained solution is uniform, and filtering and packaging the uniform solution. The coating is used for coating the back sides of coated paper, transfer cardboards and composite cardboards for cigarette packaging to keep the paper have a stable water content and be not prone to deform, so poor printing caused by unsmooth paper feeding during printing of an UV offset printing machine and printing deviation caused by non-stability of paper back sticking wheels during high-speed rotary intaglio printing is avoided.

Description

technical field [0001] The invention relates to the technical field of cigarette wrapping paper, in particular to an environment-friendly water-based coating and a production process for ensuring the printing smoothness of the cigarette wrapping paper. Background technique [0002] Cigarette wrapping paper is an outer packaging used for decorating and printing cigarettes. It is composed of the main body of the wrapping paper and special laser patterns. Its structure is simple, but it is very practical collectively. It has better protection and It is easy to carry, and the production method of wrapping paper is relatively simple. Its special laser pattern structure plays a good role in decoration and publicity for the product itself, and it consumes less waste materials, so it is widely used in various fields. [0003] However, when the existing cigarette wrapping paper is used in production and use, it is easy to cause paper warpage, roll-up (squatting down) and other deform...

AI Technical Summary

Problems solved by technology

[0003] However, when the existing cigarette wrapping paper is used in production and use, it is easy to cause paper warpage, roll-up (squatting down) and other deformations that affect the flatness of the paper due to the loss and intrusion of moisture. Unsmooth and high-speed gravure printing on the back of the paper is unstable and printing deviation occurs, which leads to poor printing

[0004] Through the search of existing technical solutions, no environmental protection water-based coating related technology related to the printing smoothness of cigarette wrapping paper has been found
