Abstract

The invention discloses a hydrophilic antibacterial coating of aluminum-foil paper for cigarettes. The hydrophilic antibacterial coating is prepared from polyvinyl butyral (PVB) resin, polyacrylamide (PAM) resin, isothiazolone, a chitosan-copper complex, GR organic dye yellow, GR organic dye red, GR organic dye black, tap water, polyethylene wax as an antiwear agent, titanium dioxide, rosin and 95% ethanol. The coating is beneficial to the improvement of the quality and definition of a printed product, has good water resistance, is low in volatile substance content and strong in practicability, has excellent printing viscosity stability and low-combustion safety,is capable of improving the working environments of printing workers, simplifying the printing cleaning workload and increasing the production efficiency and can be popularized in food packaging and printing industries.

Description

technical field [0001] The invention relates to a printing paint, in particular to a hydrophilic and antibacterial paint for aluminum foil paper for cigarettes. Background technique [0002] The current printing coating system of alcohol-soluble polyurethane fatty acid styrene system has fast drying speed and poor water resistance. The working environment of printing workers is excessively exposed to benzene, xylene, arsenic, lead, mercury, cadmium, nickel, and chromium. Long-term exposure to styrene ink can irritate the eyes and upper respiratory tract mucous membranes. Although it is much less toxic than benzene, it can irritate the respiratory tract of printers and sometimes cause obstructive pulmonary lesions. Rough, chapped, and thickened skin. Reduce white blood cells, reduce hemoglobin, cause harm to the human body, and the workload of printing and cleaning is large, resulting in low production efficiency. Contents of the invention [0003] Aiming at the deficien...
