Water transfer printing paper capable of being printed through water-based printing paste and preparation method of water transfer printing paper

Abstract

The invention relates to water transfer printing paper capable of being printed through water-based printing paste. The water transfer printing paper sequentially comprises a surface coating, a middle coating, a bottom coating, base paper and a back coating from outside to inside. A hydrophobic coating is further arranged on the surface of the surface coating. A preparation method of the water transfer printing paper capable of being printed through the water-based printing paste comprises the production steps that A, the base paper is unwound, the bottom coating is subjected to coating, and drying is carried out; B, the middle coating is subjected to coating, and drying is carried out; C the surface coating is subjected to coating, and drying is carried out; D, the hydrophobic coating is subjected to coating, and drying is carried out; E, the back coating is subjected to coating, and drying is carried out; and F, a product is obtained after winding, slitting and packaging. The water transfer printing paper has the beneficial effects that the hydrophobic coating is adopted, therefore, the surface coating is isolated when the water-based printing paste is used for printing, the printing paste and the surface coating are prevented from reacting, and the paste is molten or adsorbed.

Description

technical field [0001] The invention relates to the field of printing, in particular to water-transfer printing paper that can be printed with water-based printing materials and a preparation method thereof. Background technique [0002] With the continuous improvement of people's living standards, in addition to practicality, more attention is paid to aesthetics of the objects used. Therefore, various coating technologies have been released. Gradually, some rigid product shells have been painted with three-dimensional paintings to give objects protection. Beautification and other desired effects create a new and better surrounding environment, thereby enriching people's lives and adding a comfortable view. [0003] The general printing process can only be applied to flat surfaces, and it is difficult to print on concave and convex surfaces. Therefore, the development of water transfer printing technology overcomes the inability of general traditional printing technology and...

Problems solved by technology

[0004] However, traditional water-transfer printing paper can only use oil-based printing materials for pattern printing. If water-based printing materials are used for printing, its water-soluble surface coating is easily dissolved or partially dissolved during the printing process. As a result, the adhesion between the printing material and the base paper increases, and it will be difficult to separate from the base paper during water transfer printing, and even cause damage to the printed pattern

[0005] Although oil-based printing materials are cheap and easy to purchase, oily printing materials contain a strong pungent smell and a large amount of harmful substances in the gas. Generally, the strong pungent smell evaporates to basically tasteless after 1-2 months of use. However, a large amount of harmful gas will still be slowly released and volatilized for 10-15 years, seriously affecting the health of production workers. Even if the gas is sent out of the workshop, it will also pollute the surrounding atmosphere; moreover, the waste of oily printing materials is discharged into the sewer and eventually flows to The surrounding river surges also cause serious damage to the surrounding environment
