Resin for alcohol soluble ink vehicle and method for preparing same

Abstract

The invention belongs to the technical field of ink vehicles, in particular to resin for an alcohol soluble ink vehicle and a method for preparing the same. The resin comprises the following components in part: 12 to 17 parts of acrylic acid, 40 to 60 parts of styrene, 120 to 160 parts of methyl methacrylate, 25 to 35 parts of methacrylic acid dimethylamino ethyl ester, 45 to 55 parts of butyl acrylate, 17 to 23 parts of acrylic acid beta-hydroxyl ethyl ester, 130 to 170 parts of butyl methacrylate, 12 to 15 parts of alfa-alfa'-azoic-isobutyronitrile, 270 to 350 parts of anhydrous alcohol, 90 to 110 parts of acetic ether, and 130 to 170 parts of isopropyl alcohol. The resin for the vehicle has the advantages of wide compatible range, good film forming property, pigment wetting dispersibility, high transparency, brightness and adhesive force; and the resin of the invention is the resin used for preparing benzene free and ketone free plastic ink vehicles, and can greatly lower environmental pollution and belongs to the environment friendly type product.

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...

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 environmental facilities It is also difficult to remove benzene and xylene; printing plastic packaging bags for packaging food with benzene-soluble ink will cause food pollution due to the residue of benzene, xylene and various heavy metals; the volatilization of benzene and xylene will cause Toxic gas is produced, which will cause serious physical and mental harm to workers if they inhale it for a long time during the production process

In short, the current benzene-soluble inks will cause serious pollution to air, water sources, food, etc., and will also cause great harm to the working environment and physical and mental health of workers. At the same time, the gloss, transparency and resistance of such ink products are also poor.
