Problems solved by technology

[0006] The technical problem mainly solved by the present invention: the existing fountain solution generally contains alcohols such as isopropanol, and the alcohol vapor produced after volatilization is poisonous, pollutes the environment and endangers human health, and the wettability and stability Poor, the ink is easy to emulsify after use, and it will have a bad effect on the drying of the ink. This method first extracts fish oil from the fatty cavalier, and then saponifies it with alkali to obtain a saponified product, supplemented by tea saponin Fountain solution can be prepared after using , gum and acid electrolyte. In the present invention, fish oil saponification is used instead of isopropanol, which reduces the surface tension of water and increases the viscosity of fountain solution, so that water can be wetted more evenly. Rely on the water roller to form a thicker water film on the water roller, thereby improving the performance of the ink, paper and printing plate, and achieving a better and faster water-ink balance, which solves the problem that the traditional dampening solution is easy to pollute the environment and harm the human body Healthy and poor wetting properties and stability issues, with broad application prospects

example 1

[0019] First, remove the scales from the cao white fish, cut open the maw and take out the viscera, rinse it repeatedly with deionized water for 5 minutes, then cut 3 incisions with a length of 2 cm on each side of the maw, fill the maw with millet, and wrap the maw with wire Re-stitch to get the pre-treated Caobaiyu; then build a 1.0m-high stone furnace with bricks, first light pear branches in the stone furnace and use a blower to blow air to support the combustion, continue to add branches to heat the furnace wall for 3 hours, then put the above The pre-treated white fish is hung on the top of the stone furnace, and the white fish is roasted with the heat generated by the furnace wall, and the fish oil dripping from the white fish is collected at the bottom of the furnace; 50g of the fish oil obtained above is added to the reaction kettle After heating to 95°C, add 9.3g of potassium hydroxide to the reaction kettle, stir and react for 3 hours, wait for it to cool down to roo...

Abstract

The invention discloses a preparation method of an environment-friendly non-alcoholic fountain solution, relating to the technical field of fountain solutions. The method comprises following steps: firstly, extracting fish oil from fatty Chinese herring; making saponification reactions with alkali to obtain saponification resultants by supplementing with tea saponin, gums and acid electrolytes such that the fountain solution is prepared. The preparation method of the environment-friendly non-alcoholic fountain solution has following beneficial effects: by replacing isopropanol with saponated substance of fish oil, surface tension of water is reduced and viscosity of the fountain solution is improved such that water can dampen a form roller more uniformly; therefore, a thick water film is formed on a water roller such that performance of printing ink, paper and a printing plate; water and ink balance can be better achieved so that the problem that a conventional fountain solution may easily pollute the environment, be harmful to people's health and have poor wettability and stability is solved; and the preparation method has a broad application prospect.

Description

technical field [0001] The invention discloses a method for preparing an environment-friendly alcohol-free fountain solution, which belongs to the technical field of fountain solution preparation. Background technique [0002] Offset printing is the main printing method today. The height difference between the image part and the non-image part of the printing plate is very small, only about 2 microns. The printing process is the process of water and ink balance; The role of pollution. [0003] Offset printing uses the two natural laws of immiscibility of oil and water and selective adsorption of solids to liquids, and builds the copied graphics and blank parts on the surface of the unified printing plate after technical treatment, so that the blank part has Strong water absorption performance, the graphic part is lipophilic and water repellent. In the printing process, water is supplied to the entire printing plate first, so that the blank part of the layout absorbs water ...
