Embodiment 1

[0018] A kind of alcohol-free dampening solution concentrate, comprises following components and is made (consumption is weight part):

[0019] C 12-18 Fatty alcohol polyoxyethylene (10) ether 2

[0020] C 8-10 Alkyl glucoside 1

[0021] Gum Arabic 5 Citric Acid 1

[0022] Sodium Gluconate 3 Sulfonylated Glucosamine 5

[0023] Phosphoric acid 1 Disodium hydrogen phosphate 3

[0024] Defoamer 0.1 Antiseptic bactericide 0.2

[0025] water 20

[0026] Weigh the above raw materials in proportion, dissolve the solid into a solution with water, dilute the liquid, then add various raw materials into the reaction kettle, stir for 30-45 minutes, and then the finished product is produced. The prepared dampening solution concentrate is diluted with water to a 2-3% aqueous solution, which is the directly used dampening solution.

Embodiment 2

[0028] The non-alcoholic fountain solution concentrate in the present embodiment comprises following components to make (consumption is parts by weight):

[0029] C 12-18 Fatty alcohol polyoxyethylene (10) ether 4

[0030] C 8-10 Alkyl Glucoside 3

[0031] Gum Arabic 15 Citric Acid 3

[0032] Sodium Gluconate 5 Sulfonylated Glucosamine 16

[0033] Phosphoric acid 3 Disodium hydrogen phosphate 5

[0034] Defoamer 1 Antiseptic bactericide 2.5

[0035] water 30

[0036] Weigh the above raw materials in proportion, dissolve the solid into a solution with water, dilute the liquid, then add various raw materials into the reaction kettle, stir for 30-45 minutes, and then the finished product is produced. The prepared dampening solution concentrate is diluted with water to a 2-3% aqueous solution, which is the directly used dampening solution.

Embodiment 3

[0038] The non-alcoholic fountain solution concentrate in the present embodiment comprises following components to make (consumption is parts by weight):

[0039] C 12-18 Fatty alcohol polyoxyethylene (10) ether 6

[0040] C 8-10 Alkyl glucoside 5

[0041] Gum Arabic 35 Citric Acid 7

[0042] Sodium Gluconate 10 Sulfonylated Glucosamine 24

[0043] Phosphoric acid 8 Disodium hydrogen phosphate 10

[0044] Defoamer 2 Antiseptic and fungicide 5

[0045] water 50

[0046] Weigh the above raw materials in proportion, dissolve the solid into a solution with water, dilute the liquid, then add various raw materials into the reaction kettle, stir for 30-45 minutes, and then the finished product is produced. The prepared dampening solution concentrate is diluted with water to a 2-3% aqueous solution, which is the directly used dampening solution.

Abstract

The invention discloses an alcohol-free fountain solution condensate. The process for preparing the alcohol-free fountain solution condensate comprises the following steps: proportionally weighing fatty alcohol-polyoxyethylene ether, coco-glucoside, Arabic gum, citric acid, sulfonylation dextrosamine, gluconic acid sodium salt, phosphoric acid and disodium hydrogen phosphate; dissolving the solid materials in water into solution, and diluting liquid materials in water; respectively putting the materials into a reaction kettle; and stirring for 30 to 45 minutes to obtain the alcohol-free fountain solution condensate. The alcohol-free fountain solution condensate does not contain alcohol or isopropanol, and can be used after being diluted by water into 2-3 percent solution. Fountain solution prepared from the alcohol-free fountain solution condensate not only ensures that the printing has high definition, vivid effect and wide application, but also has no harm to human body and no pollution to the environment. Compared with market fountain solution which consumes large amount of alcohol or isopropanol or alcohol-reduced fountain solution, the alcohol-free fountain solution condensate greatly reduces the cost.

Description

technical field [0001] The invention relates to a printing fountain solution, in particular to an alcohol-free fountain solution concentrate. Background technique [0002] With the development of science and technology, people pay more and more attention to health, environmental requirements, energy saving and emission reduction. At present, commercially available fountain solutions consume a lot of alcohol or isopropanol or other organic solvents. Alcohol and isopropanol can reduce the surface tension of the system, increase the viscosity of the fountain solution, and make it easier to transfer water to the printing plate. To achieve good printing effect. However, alcohol and isopropanol are volatile, and the incidence of respiratory diseases among printing employees is high, and even the incidence of lung cancer is more than twice that of ordinary workers, which causes great harm to the health of printing workers; and the production of alcohol consumes a lot of energy An...
