Problems solved by technology

[0003] Its disadvantages are: due to the manufacture of ink, especially in the printing process, the printed matter is dried by volatilization of solvent at room temperature. At present, solvent-based plastic inks are mostly limited to benzene, ketone, etc. as solvents, so benzene, The volatilization of solvents such as xylene and ketone not only causes serious pollution to the air in the production operation area, but also to the entire atmospheric environment; When cleaning, a large amount of benzene and xylene will be discharged into the sewage, causing water pollution. For some underdeveloped areas, it will cause serious pollution to its rivers and wells. For secondary water in areas with relatively complete environme

Description

technical field [0001] The invention belongs to the technical field of ink binders, in particular to a resin for alcohol-soluble ink binders and a preparation method thereof. Background technique [0002] In recent years, with the emergence of new materials and the rapid development of the packaging industry, the demand for the ink market is increasing. The types and quantities of inks are increasing, and the performance requirements for them are also getting higher and higher. At present, solvent-based plastic inks are mostly limited to polyamides and alkyd resins that use benzene, ketone, etc. as solvents or heavy metal salts as catalysts as binders. [0003] Its disadvantages are: due to the manufacture of ink, especially in the printing process, the printed matter is dried by volatilization of solvent at room temperature. At present, solvent-based plastic inks are mostly limited to benzene, ketone, etc. as solvents, so benzene, The volatilization of solvents such as xyl...
