Embodiment 1

[0018] Embodiment 1: Preparation of fountain solution

[0019] A green printing dampening solution prepared from the following components by weight (kg): Camellia oleifera seed cake 20, aluminum oxide 1.5, sodium bicarbonate 2, potassium hydroxide 0.4, sodium stearate 2, spermaceti Polydimethylsiloxane 0.8, Isooctyl Hexadecanoate 3, Sucrose Monolaurate 3, Gamma-Polyglutamic Acid 2, Chitosan 6, Tartaric Acid 3, Methylparaben 0.8, Additive 8, water 50;

[0020] Among them, the auxiliary agent is made of the following raw materials by weight (kg): sodium tripolyphosphate 1.5, polyethylene glycol 2, sodium alginate 1.5, chitosan 7, gelatin 6, citric acid 2, sage oil 1.5, white carbon Black 0.8, sodium citrate 20, talcum powder 0.4, water 50; dissolve citric acid, sodium citrate, sodium alginate, chitosan, gelatin and sodium tripolyphosphate in water, first stir at 800r / min for 15min, then add Stir the remaining raw materials at 60°C for 15 minutes, filter after cooling, and obta...

Embodiment 2

[0024] Embodiment 2: the mensuration of ink emulsification rate

[0025] Offset printing requires moderate emulsification of the ink during the printing process, but too high an emulsification rate will affect the balance of water and ink, resulting in poor offset printing effect. According to the principle of printing water-ink balance, ink emulsification should form a W / O emulsion, which is beneficial to compete with the ink on the printing plate with the least amount of liquid supply, so the ink emulsification rate should be controlled below 26%.

[0026] Determination of ink emulsification rate C: by weight method.

[0027] Dilute the dampening solution in Example 1 to 5% with distilled water, add 15g of lithographic printing black ink and 15g of diluted dampening solution to the container at one time, stir at 100r / min for 1h and then let it stand for 15min, and remove the unabsorbed dampening solution The plate liquid and the ink are separated in layers, weighed, and the...

Abstract

The invention discloses a green printing fountain solution. The green printing fountain solution is characterized by being composed of, by weight, 15-25 parts of camellia seed cake meal, 1-2 parts of aluminum oxide, 1-3 parts of sodium bicarbonate, 0.2-0.5 part of potassium hydroxide, 1-3 parts of sodium stearate, 0.5-1 part of cetyl dimethicone, 2-4 parts of 2-ethylhexyl hexadecanoate, 2-4 parts of sucrose monolaurate, 1-3 parts of gamma-polyglutamic acid, 4-8 parts of chitosan, 2-4 parts of tartaric acid, 0.5-1 part of methyl 4-hydroxybenzoate, 5-10 parts of auxiliaries and 40-60 parts of water. The fountain solution saves resources, reduces cost and emission of organic volatile matters and is green and environmentally friendly.

Description

technical field [0001] The invention relates to a printing fountain solution, in particular to a green printing fountain solution and a preparation method thereof. Background technique [0002] The characteristic of lithographic printing is that the non-inked and inked parts of the printing plate are on the same plane. The blank part is hydrophilic and oleophobic, and the graphic part is lipophilic and hydrophobic. During printing, ink-repellent water is formed on the blank part by adding fountain solution. The film, and then ink the printing plate, so that the part of the image and text is inked, and the ink is transferred to the surface of the substrate under the pressure of printing during printing, thus completing a printing. The function of fountain solution is to ensure the balance of water and ink, which plays a vital role in this process. [0003] In recent years, the country has put forward the concept of low-carbon green environmental protection, which has become ...
