Diluting agent for transferring printing paste

Abstract

The invention relates to a diluting agent for transferring printing paste. The diluting agent comprises the following ingredients in mass percentages: 3 to 6 percent of PVB (polyvinyl butyral) and 94 to 97 percent of auxiliaries, wherein the auxiliaries are mixtures of methanol and isobutanol. When the environment temperature is lower than 10 DEG C, the volume ratio of the methanol to the isobutanol is 3:(1-1.5). When the environment temperature is 10 to 30 DEG C, the volume ratio of the methanol to the isobutanol is 1:(1-1.5). When the environment temperature is higher than 30 DEG C, the volume ratio of the methanol to the isobutanol is (1-1.5):3. The diluting agent has the following advantages that (1) PVB with different performances is selected for combination so that the paste meets a certain depth requirement, and the transfer printing color difference is controlled; and (2) the proper auxiliaries (the methanol and the isobutanol) are added into the diluting agent, so the storage of the used rest paste is more stable, and the production cost is saved.

Description

technical field [0001] The invention relates to a diluent, especially a diluent for transfer printing paste. Background technique [0002] Transfer printing is to print disperse dyes on printing paper through a special printing plate (gravure), and then use the principle of high temperature sublimation of disperse dyes to transfer the pattern on the printing paper to the required fabric. [0003] With the development of the transfer printing industry, customers have higher and higher requirements for colors, and transfer printing shows rich layering effects because of the use of layered transition printing plates. The disperse dye is printed on the printed paper by printing, and transferred to the printed fabric after high temperature. Due to the difference in the performance of printing paper, the performance of printing paste will change accordingly, resulting in light color penetration and inconsistent color development efficiency, and changes in weather and temperature,...

Problems solved by technology

For example, Japan's Sekisui Chemical's PVB has stable quality, good fluidity and the ability to prevent light color shifting, but in mass production operations, it will produce white silk, oily silk, etc.; and Tianjin Everbright Bingfeng Chemical Co., Ltd. PVB products have poor fluidity, weak film-forming performance, adhesion to paper and anti-color shifting ability, but good printing performance (less white silk)
