(2) temperature is adjusted to 50-60 DEG C, adds alkylolamide, amido silicon oil, gelatin, tripoly phosphate sodium STPP and auxiliary agent 600-800rpm and stir 15-30min;
(3) being cooled to room temperature, add rest materials, be stirred to and dissolve completely, filtering and impurity removing matter gets product.
Embodiment 2: the test of fountain solution performance
1, water-pickup of ink
Fountain solution mainly affects ink-water balance performance in printing process, and wherein water-pickup of ink is an important parameter. Be there is material impact by the character of fountain solution in water-pickup of ink. According to offset printing principle, in offset printing process, water-pickup of ink is feasible lower than 26%.
The mensuration of water-pickup of ink C: adopt weighting method.
By fountain solution distilled water diluting to 3% described in embodiment 1, once add the fountain solution after 50g black ink and 50g dilution in a reservoir, 100r/min stirs and leaves standstill 10min after 1h, by the fountain solution that do not absorb and ink multi_layer extraction, is calculated as follows water-pickup of ink:
Measurement result water-pickup of ink is 19.39%, far below the 26% of ultimate value, in normal range, is conducive to print production.
2, corrosion inhibition
Static steel weight-loss method is adopted to measure corrosion inhibition. The Q235 steel disc weighed is put into tap water at normal temperatures and pressures respectively that do not add fountain solution He add fountain solution described in embodiment 1 (final concentration 3%), and steel disc surface-area and tap water volume ratio are 1:15, and hanging the sheet time is 7d. Hang after sheet terminates, wash corrosion removal product, clean that clean after-blow is dry weighs. Calculating inhibition efficiency by the weight loss of steel disc before and after corrosion, formula is as follows:
�� W in formula0It is poor that blank solution hangs quality before and after sheet;
It is poor that �� W adds quality before and after the solution extension sheet of fountain solution
Recording inhibition efficiency is 68.32%, and corrosion resistance is good, the requirement of realistic use.
