Problems solved by technology

The cleaning agents currently used are mainly pure solvent-based solvents such as gasoline and kerosene. There are many disadvantages in using pure solvent-based cleaning agents such as gasoline and kerosene to clean ink rollers and blankets: First, gasoline and kerosene contain volatile substances. Low, it is easy to cause dangerous accidents such as fire, large consumption, high cost, serious environmental pollution, and great harm to the health of employees; second, a large amount of aromatic compounds contained in gasoline and kerosene are easy to make the rubber of the ink roller Swelling will affect the printing quality, and the cleaning effect on water-soluble dirt such as paper hair, paper powder, and gum arabic attached to the ink roller is not good, and various impurities are easy to accumulate on the surface of the ink roller layer by layer, making the ink roller transfer ink Performance decline affects the printing effect; thirdly, gasoline and kerosene consume a lot of oil, causing a certain burden on environmental resources

Abstract

The invention relates to a cleaning agent, and discloses an environment-friendly printing ink cleaning agent. The formula comprises a main solvent, a cleaning aid and a rust inhibitor, wherein the main solvent is made from phosphate ester series or sodium oleate; and the cleaning aid is made of a surfactant and an emulsifier. The invention further discloses a preparation process of the environment-friendly printing ink cleaning agent. The preparation process comprises the following steps of: (1) mixing; (2) initially stirring; (3) stirring once again; and (4) preparing a finished product. A product produced according to the preparation process has the advantages of high flash point, low odor, freeness from petroleum solvents, no any chemical reaction with an ink roll, content of chlorine elements consistent with the International environmental protection standard, high cleaning efficiency, good effect and small using amount.

Description

technical field [0001] The invention relates to a cleaning agent, in particular to an environment-friendly ink cleaning agent and a preparation process. Background technique [0002] At present, the main body of the printing industry in the world is offset printing. The ink is transferred to the substrate through ink rollers and blankets. To ensure the normal operation of the ink rollers and blankets, regular cleaning and maintenance are required. The cleaning agents currently used are mainly pure solvent-based solvents such as gasoline and kerosene. There are many disadvantages in using pure solvent-based cleaning agents such as gasoline and kerosene to clean ink rollers and blankets: First, gasoline and kerosene contain volatile substances. Low, it is easy to cause dangerous accidents such as fire, large consumption, high cost, serious environmental pollution, and great harm to the health of employees; second, a large amount of aromatic compounds contained in gasoline and ...
