Problems solved by technology

This is due to the pore structure of the ceramic soil embryo itself containing a certain amount of water. When the soil embryo is fired at a high temperature after being appliquéd, the moisture in the soil embryo will quickly turn into water vapor as the firing temperature rises, and the soil covered The oily cover oil on the surface of the embryo will form a stable layer of film, which prevents water vapor from leaking out, thus forming more air bubbles on the surface of the film layer, which in turn causes the flower surface to burst during the b

Abstract

The invention relates to the technical field of ceramic decal, in particular to small film decal paper not prone to cracking and as well as a preparation method and use method of the small film decal paper. The small film decal paper comprises backing paper, water-based varnish and alcohol-soluble cover oil printed on the backing paper and further comprises water-based decal glue used in a matched mode, the water-based varnish contains 37%-45% of water-soluble polyacrylate, the alcohol-soluble cover oil contains 20%-30% of alcohol-soluble decal glue, and the water-based decal glue contains 23%-27% of dimethyl silicone oil, 23%-27% of glycerinum, 23%-27% of ethyl alcohol and/or isopropyl alcohol and the like. Through the synergistic effect of the water-based varnish, the alcohol-soluble cover oil and the auxiliary matched water-based decal glue, and through a specific preparation technology and the use method, the decal can be tightly combined with a ceramic clay blank during decal, the probability of cracking in the firing process is reduced to the maximum extent, the cracking rate is reduced to 3% or below, during decal, the decal can be moved and is not prone to wrinkling or blistering, and the components are more environment-friendly.

Description

technical field [0001] The invention relates to the technical field of ceramic decals, in particular to a small-film decal paper that is not easy to detach and its preparation method and use method. Background technique [0002] There are mainly three types of decals that can be directly used for pasting ceramic adobes: cotton paper, large-film decals and small-film decals. Among them, cotton paper is the earliest traditional technology used, and has been eliminated due to its backward printing process; subsequently, large film decal paper (also called butyral film decal paper) replaced cotton paper in the early 1980s, but its printing The performance is poor, which is not conducive to screen printing. With the update of technology, large film decals are gradually replaced by small film decals. [0003] Small film decal paper, also known as water transfer decal paper, is to print the pattern on the backing paper with strong water absorption pre-coated with water-soluble glu...
