Waterborne polyester composite printing ink

Abstract

The invention discloses waterborne polyester composite printing ink. The waterborne polyester composite printing ink is prepared from the following components in parts by mass: 80-100 parts of polyethylene terephthalate, 25-30 parts of polyethylene glycol, 2-5 parts of dibutyltin dilaurate, 3-4 parts of ethylene glycol, 4-5 parts of xylene, 5-7 parts of diethylene glycol, 6-8 parts of fatty alcohol polyoxyethylene ether, 3-5 parts of alcohol ethoxylate, 5-6 parts isocaprylic acid, 4-5 parts tetrabutyltin, 5-6 parts of dibutyltin maleate, 4-5 parts of diethylene glycol, 5-8 parts of anhydrous citric acid, 4-5 parts of itaconic acid, 4-5 parts of dimethyl carbonate, 40-50 parts of deionized water, 40-50 parts of acrylic resin, 8-10 parts of methanesiliconic acid sodium salt, 60-65 parts of vinyl acetate-ethylene copolymer emulsion, 8-10 water-soluble varnish and 6-8 parts of pigments. The waterborne polyester composite printing ink has no chlorine, no ketone, no benzene and other harmfulsubstances, and does not cause harm to the human body and the environment when used.

Description

technical field [0001] The invention relates to the technical field of ink materials, in particular to a water-based polyester composite ink. Background technique [0002] With the development of China's economy and culture, the printing, publishing, and packaging industries have developed rapidly, and the domestic demand for printing, packaging inks, and food packaging inks has greatly increased. At present, most inks contain elements such as benzene, ketones, and chlorine. . [0003] At present, the Chinese patent with the publication number of 101255296 discloses a polyurethane resin composite ink and its manufacturing method, including polyurethane resin, vinyl chloride resin, solvent, pigment, and dispersing aid as raw materials, wherein the solvent includes doubling, methyl ethyl ketone, iso Propanol, the specific formula ratio is: polyurethane resin liquid (30% solid content): 25% to 40%, vinyl acetate resin: 0 to 4%, pigment: 5% to 25%, dispersing aid 0.2% to 0.5%, ...
