Abstract

The invention discloses a fast-curing ink binder and a preparation method thereof. The fast-curing ink binder is prepared from the following raw materials in parts by mass: 40-45 parts of resin, 30 parts of vegetable oil, 25-30 parts of ink oil and 1 part of molten aluminum. The preparation method of the quick-curing ink binder comprises the following steps: putting the vegetable oil and part of the ink oil into a reaction kettle, and performing stirring and heating; uniformly stirring the molten aluminum and part of printing ink oil at a high speed in advance; continuously adding part of the printing ink oil, performing cooling, adding the molten aluminum mixture, and performing stirring and heating. Compared with the light industry recommended QB / T2624-2012 standard, the bonding speed of the produced bonding material is greatly improved, the efficiency of printing operation can be improved, meanwhile, the gloss and the flow index also meet the standard, and no negative influence is caused on a printed matter.

Description

technical field [0001] The invention relates to an ink, in particular to a fast-curing ink binder and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of my country's national economy, the printing and packaging industry has developed rapidly, which has led to the rapid growth of printing inks. However, when the existing ink is printed on paper, due to the capillary effect of the paper, the absorption It absorbs the low-viscosity liquid components in the binder, makes the ink film dry instantly, and makes the ink stains form a relatively hard film, which can withstand the pressure of the rest of the paper and achieve light touch without sticking. It is a fast-fixing offset ink. Final drying is by oxidative drying. Ink fixation is the initial drying performance of ink on paper and other printing carriers. Slow fixation speed will not only cause the problem of backside stickiness during the accumulation process of ink print...
