Abstract

The invention discloses a benzene and ketone free high temperature resistant table printing ink. The benzene and ketone free high temperature resistant table printing ink comprises, by mass, 25-40 parts of a polyurethane resin, 10-15 parts of polyethylene vinyl acetate, 30-45 parts of an ester alcohol solvent, 0.6-1 part of propylene glycol methyl ether acetate, 5-15 parts of a pigment, 0.3-0.6 parts of a dispersant, 0.3-0.6 parts of polyethylene wax powder, 0.8-1.5 parts of an adhesion promoter, 0.8-1.5 parts of an antistatic agent, 5-10 parts of a delustering agent, 0.3-0.6 parts of an antifoaming agent, 0.3-0.8 parts of a high temperature resistant assistant, and 1-2 parts of a curing agent. The adoption of a double liquid design increases the hardness and the adhesion of an ink film, effectively prevents offsetting or ink falling, realizes excellent high temperature and boiling resistances, and increases the shelf life of the printing ink.

Description

technical field [0001] The invention relates to the technical field of ink production, in particular to a high temperature resistant ink for surface printing. Background technique [0002] For a long time, printing inks in the packaging industry have mostly been based on benzene-based solvent-based gravure plastic film inks, and benzene-based solvents will not only pollute the environment, but also cause harm to the human body. At present, many countries in the world have banned or restricted the use of benzene solvents. In addition, for external-use flexible packaging materials such as food and medicine, it is required to undergo high-temperature sterilization and environmental protection, which requires the use of suitable printing inks that are resistant to high-temperature cooking. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a benzene-free and ketone-free surface printing high-temperature resistant ink,...
