[Industrial Application Field] The present invention relates to a cleaning agent for impression cylinders of printing machines such as newspaper rotary presses. [Prior Art] Conventionally used impression cylinder cleaners include chlorinated solvents (e.g. 1,1,1-trichloroethane) and fluorinated solvents (e.g. trichloro-trifluoroethane) and hydrocarbon oils (e.g. , industrial gasoline, kerosene, mineral spirits). [Problems to be solved by the invention] Although chlorinated solvents have a great cleaning effect, they fall under the class 2 organic solvents of the Organic Solvent Poisoning Prevention Regulations, so the maximum usage amount is limited to 60g/hour. When using more than this, it is necessary to install a local exhaust system. Fluorine-based solvents do not fall under the Organic Solvent Poisoning Prevention Ordinance, but their cleaning properties are poor, so it is necessary to use a large amount, which increases costs. The above-mentioned organic solvent poisoning prevention regulations are based on the Industrial Safety and Health Act, and are classified into Types 1 to 3 depending on the degree of toxicity. In other words, type 1 (chloroform and 6 other types) > type 2 (acetone and 39 other types)
Type) > Type 3 (gasoline and 6 other types). If the air volume is 150m3 , and the usage amount per hour exceeds 12.5gr for Type 1, 60gr for Type 2, and 225gr for Type 3, equipment such as local exhaust ventilation system, general ventilation system, etc. is required. The present invention proposes a cleaning agent that is highly effective in cleaning ink stains and paper dust stains generated on the impression cylinder surface during printing, improves workability, and is low cost. [Means for Solving the Problems] The present invention solves the above problems by mixing alcohol (second type organic solvent) with hydrocarbon oil (third type organic solvent). That is, in the present invention, the hydrocarbon oil has 8 carbon atoms.
Using a petroleum solvent with a boiling point range of 100-200℃ at ~12℃,
This invention relates to a printing machine cleaning agent prepared by mixing this with an alcohol having 3 to 6 carbon atoms. In the present invention, it is a preferred embodiment that the mixing amount of the alcohol is less than 5 vol% with respect to the hydrocarbon oil. The hydrocarbon oil in the present invention includes petroleum solvents having 8 to 12 carbon atoms and a boiling point range of 100 to 200°C;
For example, mineral turpentine, mineral spirits,
Solvent naphtha, industrial gasoline, etc. are used. Further, as the alcohol in the present invention, those having 3 to 6 carbon atoms, such as i-propyl alcohol, n-butyl alcohol, n-hexyl alcohol, and cyclohexyl alcohol, are used. In the present invention, it is preferable that the amount of alcohol mixed with the hydrocarbon oil be less than 5 vol%, in terms of ink solubility.
%, but according to the organic solvent poisoning prevention regulations mentioned above, those containing more than 5 vol% of alcohol are class 2 organic solvents, which not only imposes strict standards for equipment such as local exhaust ventilation, but also increases costs. This is because you may be invited. [Function] [Effects of the Invention] In the present invention, by mixing alcohol with hydrocarbon oil, the cleaning effect can be enhanced and the dissolution range (i.e., cleaning range) can be widened compared to the case of using only hydrocarbon oil. and strong dissolution (ie, washing) can be achieved. In addition, in the present invention, when the amount of alcohol is mixed with hydrocarbon oil at less than 5 vol%, this mixed solvent falls under the class 2 organic solvent, and even if the amount used is within 225 gr/hour in a volume of 150 m3 . For example, local exhaust ventilation equipment is not required. [Example] The cleaning agent of the present invention is sprayed onto the impression cylinder surface from a spray nozzle of an automatic cleaning device in order to wash and remove ink and paper dust stains that adhere to the impression cylinder surface during operation, for example in a newspaper rotary printing machine. The ink and paper dust stains are dissolved and dispersed, and then wiped off with printing paper. Note that the cleaning operation is usually performed intermittently (usually for 15 to 20 minutes), and the printed matter during that time is disposed of as waste paper because it has solvent and dirt attached to it. Cleaning power test: Apply a certain amount of black ink on a glass plate,
The glass plate was tilted at 50°, and a certain amount of cleaning liquid was flowed down from the top for a certain period of time, and the amount of ink on the glass plate before and after cleaning was measured and compared. The results were as shown in Table 1.
