Embodiment 1
[0021] This embodiment discloses an alcohol-free printing fountain solution, which is composed of the following raw material components in percentage: polyethylene glycol 8-15%, film-forming agent 5-8%, thickener 0.5-1% , Diethylene glycol butyl ether 5-8%, propylene glycol 5-10%, decynediol 7-12%, foam inhibitor 0.2-0.5%, polyether 2-5%, the first surfactant 2-5 %, 1-1.5% of the second surfactant, 20-35% of the buffering agent, 0.2-0.5% of the preservative, and 35-45% of water; -10%, Phosphatidylethanolamine 1-3%, Triethanolamine 1-5%, Sodium Gluconate 2-10%, Tween 201-5%, Citric Acid 1-5%, Sodium Citrate 5-15%, Olive 1-3% oil, 0.1-0.5% vitamin E, 30-60% water; under the condition of 70-80°C water bath, add the gum arabic, the phosphatidylethanolamine, and the triethanolamine into the water at a speed of 200rpm 1. For the Tween 20 and the olive oil, stop the water bath after 1 hour, cool to room temperature and add the remaining raw materials, stir at 200 rpm until completel...
Embodiment 2
[0031] This embodiment discloses an alcohol-free printing fountain solution, which consists of the following raw material components in percentage terms: 9% polyethylene glycol, 6% film-forming agent, 0.7% thickener, butylene glycol Ether 7%, Propylene Glycol 6%, Decynediol 9%, Foam Inhibitor 0.3%, Polyether 3%, Primary Surfactant 3%, Second Surfactant 0.7%, Buffer 20%, Preservative 0.3 %, water 35%; the film-forming agent is made up of the following raw material components in percentage: gum arabic 9%, phosphatidylethanolamine 2%, triethanolamine 4%, sodium gluconate 8%, Tween 204%, citric acid 3%, 10% sodium citrate, 1.7% olive oil, 0.3% vitamin E, 58% water; under the condition of 70-80°C water bath, add the gum arabic, the phosphatidylethanolamine, The triethanolamine, the Tween 20 and the olive oil were stopped in the water bath after 1 hour, cooled to room temperature and the rest of the raw materials were added, stirred at 200 rpm until completely dissolved, and the sol...
Embodiment 3
[0036] This embodiment discloses a method for preparing an alcohol-free printing fountain solution, and the method is used to realize the alcohol-free printing fountain solution described in Example 1.
[0037] The steps of the preparation method are:
[0038] Step S1. Weigh the raw materials according to the formula, add the water into the glass container, adjust the temperature to 60-80°C, and adjust the speed to 600-800rpm. After the temperature is stable, add the polyethylene glycol and the diethylene glycol Diol butyl ether, the propylene glycol, the decynediol, and the polyether are stirred for 15-30 min;
[0039] Step S2, after cooling to room temperature, pour into a high-speed homogenizer, add the foam inhibitor and the film-forming agent, and process at 10000rpm for 15-30min;
[0040] Step S3, adding the remaining raw materials, stirring at room temperature until completely dissolved, and filtering to remove impurities to obtain the finished product.
[0041] Weigh...
