Problems solved by technology

[0002] In the prior art, there are two types of ink cleaning agents (hereinafter referred to as car washing water) used for cleaning up lithographic printing machines. Volatile, serious environmental pollution, there are potential safety hazards, and can not remove impurities such as paper wool and inorganic salt compounds adhering to the surface of the ink roller and blanket, and also have a swelling effect on the ink roller and blanket, the other is made of organic It is composed of a mixture of solvents, surfactants and related additives. Compared with gasoline and kerosene, it generally has the advantages of high efficiency, energy saving, environmental protection and safety.
However, most of the car wash water commonly used for lithographic printing machines is suitable for plain areas, without considering the low pressure and low temperature climate conditions in plateau areas. Most of the car wash water contains a large amount of volatile organic substances, which will volatilize more under low pressure conditions Fast, not only affects its use effect, but also is not easy to dry, which will increase the cost of use, so this kind of car wash water has certain limitations in the use of low pressure and low temperature climate conditions in plateau areas

Embodiment 1

[0060]Example 1, 38 parts of formic acid, 15 parts of dichloromethane, 38 parts of ethanol and 2 parts of terpineol are placed in a container together, and after stirring evenly, it becomes a colorless transparent liquid; after that, it is first tested under normal temperature and pressure conditions Its cleaning effect and volatility, record relevant data, the specific method is the same as that described in the previous sixth, and test its flash point and P H value, the cleaning effect is visually observed that the ink disperses quickly and has no residue, and takes high-definition photos for comparison, which is equivalent to the cleaning effect of KY181, and records the consumption; then, simulate the conditions of the plateau area (as described in the sixth above) Test its cleaning effect and volatility, and record relevant data. The specific method is the same as that described in the sixth above.

[0061] The implementation methods and tests of other embodiments are the...

Abstract

An ink cleaning agent suitable for use in plateau areas and a preparation method thereof, which belong to the field of chemicals, mainly provide an ink cleaning agent suitable for use in plateau areas; use parallel comparative experiments to screen basic technical solutions, and then adjust the The screened high-boiling-point modified organic solvent is added to it for modification. The ink cleaning agent is a colorless and transparent liquid with a pH of 7-8 and a flash point of 55-65°C. 35-55 parts of formic acid or / and citric acid, 10-25 parts of dichloromethane, 1-5 parts of organic modified solvent terpineol or n-octanol, 30-40 parts of methanol or glycerol, and liquid 1 to 3 parts of paraffin; compared with ordinary ink cleaning agents in plain areas, the cleaning effect is better, the consumption is less, and the drying is fast; preparation, transportation, storage and use are safe and environmentally friendly; especially suitable for cleaning lithographic printing machines in plateau areas, preparation and Low cost of use.
