Abstract

The invention discloses offset printing ink and a preparation method thereof, and belongs to the field of offset printing. The offset printing ink consists of 65-80 parts of a binder, 15-25 parts of a pigment and 1-10 parts of an additive; the cerate includes linseed oil, mineral oil and beewax; the beewax mainly consists of lipids, free acids, free alcohols and hydrocarbons, contains only only a polar group but also a non-polar group, and differs from C24 to C34 in carbon chain length; the cerate is compatible with both internal lubricating function and external lubricating function; most importantly, the application discovers that the prepared cerate can balance internal and external lubricating functions under coaction of the linseed oil, the mineral oil and the beewax, and can effectively solve a problem that the offset printing ink sticks on ink roller on the premise that gelation is not affected, so that printing quality is effectively improved, cleaning and maintenance costs of printing machine are reduced, and working efficiency of the printing machine is increased; and the preparation method is simple in step and low in process cost.

Description

technical field [0001] The invention relates to an offset printing ink and a preparation method thereof, belonging to the field of offset printing. Background technique [0002] With the progress of the printing industry, the continuous improvement and improvement of printing technology and printing equipment, offset printing has been favored by its unique advantages, such as fast and convenient plate making, low cost, high printing quality, wide range of paper use, and large printing quantity shrinkability. Favored by printing manufacturers at home and abroad, it has developed rapidly and extensively, and then occupies a leading position in the international printing industry, and offset printing ink has also developed rapidly. [0003] As the most important printing material for information reproduction, ink should have good printability during printing. Offset printing ink is mainly composed of colored pigments (dyes, etc.), binders, fillers and additives, which are mixe...
