Abstract

The green detergent for cleaning print ink in printing machine is prepared with the main materials including kerosene 50-500 weight portions, water 50-500 weight portions, dehydrated sorbierite cetylate 2.5-25 weight portions and Tween-20 2.5-25 weight portions. Its preparation process includes mixing, dissolving, heating, stirring and catalysis. As one environment protecting and energy saving product, the present invention has no toxicity and no harm, and can reduce environment pollution, prolong the service life of rubber fabric and rubber roller in printing machine, eliminate print ink and other dirt fast. It is superior to gasoline in clean effect, clean speed, consumption, cost, etc.

Description

technical field [0001] The invention relates to a cleaning agent, in particular to an environment-friendly cleaning agent for cleaning printing ink. Background technique [0002] At present, most printing manufacturers in my country still use gasoline as a cleaning agent for cleaning the rollers of printing machines. The main reason is that the price of gasoline is low. However, gasoline is divided into unleaded gasoline and leaded gasoline. Although unleaded gasoline does not contain lead compounds that can be directly absorbed by human skin and cause lead poisoning, it contains n-pentane and n-hexane with very low boiling points. A volatile oil composed of alkanes. The volatile oil has the effect of inhibiting the central nervous system of the human body, which will cause blood poisoning of the staff, which is extremely harmful. The flash point of gasoline is 21°C. It is a highly volatile and flammable liquid. When cleaning the ink roller with gasoline, gasoline molecule...
