Water transfer printing process and application of water transfer printing process to concrete products

Abstract

The invention provides a water transfer printing process and application thereof to a concrete product, and the water transfer printing process comprises the following steps: S1, carrying out surface treatment and surface activation on an irregular product, and placing the irregular product in an environment of 40-45 DEG C for later use; s2, the water transfer printing coating film is soaked in water, and an activating agent is sprayed; s3, immersing the irregular product treated in the step S1 into water to transfer the image-text layer on the irregular product; s4, taking out the irregular product subjected to transfer printing in the step S3 from water, and washing with water to remove a superfluous floating layer on the surface; s5, drying moisture on the surface of the irregular product; s6, a sealing liquid is sprayed, and standing and curing are conducted; and S7, the sealing adhesive emulsion is sprayed, drying and curing are conducted, and water transfer printing is completed. According to the process, surface treatment and surface activation are conducted on the irregular product to be subjected to transfer printing, impurities on the surface of the irregular product are removed, the transfer printing success rate of water transfer printing is increased, an image-text layer is attached to the irregular product more tightly, the transfer printing effect of water transfer printing is improved, and the service life of water transfer printing is prolonged.

Description

technical field [0001] The invention relates to a water transfer printing process and its application on concrete products, and belongs to the technical field of water coating transfer printing. Background technique [0002] With the continuous improvement of people's living standards, people's requirements for the aesthetics of objects appearing in daily life are also getting higher and higher. Therefore, more and more products are engraved or printed and dyed to add an appropriate amount of patterns to improve the aesthetics of the products. However, there are still many irregular products in daily life, and there are few engraving or printing methods for their patterns. The common method of printing patterns on irregular products is spraying process or printing patterns on stickers and pasting them on irregular products. However, the pattern printed by the spraying process is easy to be blurred, and the method of sticking with self-adhesive is easy to fall off, which cann...

Problems solved by technology

However, water coating transfer printing is often used on plastics, resins, porcelain, glass and metal products, such as the surface treatment process of a transparent material disclosed in the patent of invention with the application publication number CN110254104A, that is, in the existing water coating Improve the transfer printing process to ensure that products with light sources can also print various patterns through the water coating transfer printing process, but due to the rough surface and poor adhesion of concrete products, it is difficult to show a good transfer printing effect, and It is very easy for the transfer pattern to fall off and crack, and the water coating transfer process is seldom used in concrete products. The present invention provides a water transfer process to improve the efficiency of water transfer printing and its application effect on concrete products.
