Preparation method ad use method of PP paster

Abstract

The invention relates to a preparation method and use method of a PP paster. Glue preparation, bottom coating and a PP film technology are combined, shrinkage deformation of the whole product is prevented, the product can be displayed with bright color and high color saturation, and corrosion resistance and shrinkage deformation resistance of the whole product can be effectively ensured when an eco-solvent is used for printing. According to the disclosed use method of the PP paster, the pasting technology is simple, the pasting efficiency is high, after pasting, the bright-color high-color-saturation displaying effect can be achieved, no blisters exist on the surface, and edge warping does not occur. Meanwhile, after use, glue is easy to remove, the PP paster is especially suitable for large-scale pasting, the process is simple, less time is consumed, the accuracy is high, and time and labor are saved.

Description

technical field [0001] The invention relates to the technical field of PP direct-face stickers, and more specifically, to a method for preparing PP direct-face stickers and a method for using the same. Background technique [0002] With the development of science and technology, weak solvent PP direct-face stickers will be used in all walks of life, such as marking for learning, wall stickers for decoration to beautify indoor space, weak solvent PP direct-face stickers for outdoor advertising, etc. . At present, many face-to-face stickers, due to the colorful and multi-pattern requirements of their decorative patterns, generally use water-based solvents to spray patterns; when printing with solvent and weak solvent equipment, due to the large amount of ink and full-page printing, due to solvents on PVC Corrosion will cause PVC shrinkage and deformation, and it will easily cause edge warping when pasting in the later stage, and the temperature resistance is not high during p...

Problems solved by technology

At present, many face-to-face stickers, due to the colorful and multi-pattern requirements of their decorative patterns, generally use water-based solvents to spray patterns; when printing with solvent and weak solvent equipment, due to the large amount of ink and full-page printing, due to solvents on PVC Corrosion, resulting in shrinkage and deformation of PVC, prone to edge warping when pasting in the later stage, and the temperature resistance is not high during printing

[0003] In addition, after posting, the color is bright and saturated, and the degree of distortion is high, which cannot achieve the ideal display effect. Directly pasted on glass or smooth surface, bubbles will form, and it is not easy to post the picture, or due to the wrong posting method, warping may occur , or incorrect posting, etc., especially for a large posting surface, it takes a lot of time or a lot of manual work to post the screen
