Description
Technical Field
The invention relates to the technical field of fine chemical engineering, in particular to a high-performance fountain solution and a preparation method thereof.
Background
Offset printing is a type of offset printing, which is a printing method in which images and texts on a printing plate are transferred to a printing material by means of a rubber blanket. In China, offset printing is a printing technology with an absolutely dominating position, the principle of 'oil-water incompatibility' is utilized to carry out printing, and due to the advantages of high printing speed, relatively stable printing quality, short whole printing period and the like, the offset printing has wide application in books and periodicals, newspapers and a part of commercial printing.
The difficulty in offset printing is ink-water balance, and the fountain solution plays a key role, and the fountain solution is an indispensable chemical auxiliary agent in the printing of a color press, and forms a uniform water film on the blank part of a printing plate to resist the ink on the picture and text from infiltrating into the blank part. The existing fountain solution mainly comprises three types of common fountain solution, alcohol fountain solution and nonionic surfactant fountain solution. The common fountain solution consists of clear water, inorganic acid (weak acid), inorganic acid salt electrolyte, hydrophilic colloid and other matters. With the continuous improvement of printing technology, common fountain solution no longer meets the printing requirements and tends to be eliminated. The alcohol fountain solution usually contains isopropanol which is easy to volatilize, so that the concentration of alcohol in the fountain solution is easy to be unstable, and alcohol steam generated after volatilization is toxic, can pollute the environment and causes harm to human health. In addition, isopropyl alcohol is a photochemical oxidant, and like other trace gases present near the ground, forms ozone upon exposure to sunlight, resulting in the so-called summer smoke phenomenon, which also irritates the human eye and respiratory system. The non-ionic surfactant fountain solution has low surface tension and good wetting performance, and can reduce the consumption of the fountain solution, so that the non-ionic surfactant fountain solution becomes an ideal fountain solution in a high-speed multicolor offset press. However, the fountain solution has poor water retention and film forming properties and often damages rubber rollers. Other types of fountain solutions in the market also have the defects of environmental pollution, insufficient fountain capability and the like.
For example, chinese patent application No. 201510403405.4 discloses an environment-friendly nonionic surfactant fountain solution, which is a mixture containing deionized water, lactic acid, zinc nitrate, glycerin, alkyl glucoside, sodium dehydroacetate, polyoxypropylene polyoxyethylene glyceryl ether, and carboxymethyl cellulose; wherein the components are as follows by mass percent: 60-70% of deionized water, 4-8% of lactic acid, 3-7% of zinc nitrate, 15-25% of glycerol, 0.5-2% of alkyl glucoside, 0.9-1.5% of sodium dehydroacetate, 0.5-1% of polyoxypropylene polyoxyethylene glycerol ether and 5-15% of carboxymethyl cellulose. The zinc nitrate adopted in the formula is corrosive and has certain toxicity, so that the printing equipment is easy to damage after long-term use, and meanwhile, the recycled fountain solution can pollute the environment in the recovery process and can also damage the health of workers in the use process.
Therefore, the high-performance fountain solution which is good in environmental protection, sufficient in dampening capability, free of corrosion to printing equipment, free of foam and low in ink consumption and the preparation method thereof are still needed in the field.
Disclosure of Invention
The invention mainly aims to provide a high-performance fountain solution which has the advantages of good environmental protection, enough dampening capability, no corrosion to printing equipment, no foam and less consumption of ink and a preparation method thereof.
