Abstract

The invention discloses a preparation method of a printing ink cleaning agent for a printing machine, belonging to the technical field of printing ink cleaning agents. According to the preparation method, an AAA-type polymeric surfactant is synthesized from alpha-olefin sodium sulfonate, acrylic acid and allyl polyoxyethylene ether and is used for modifying bentonite, the surface of bentonite is coated with an anionic surfactant, ion groups and anions on printing ink particles generate electrostatic adsorption, the printing ink is gathered to form printing ink particles with relatively large particle sizes, and the printing ink is removed by virtue of a flotation method; environment-friendly anti-rusting emulsion is prepared from butyl acrylate, styrene and methylacrylic acid and is takenas a main film form substance, and a uniform dense film is formed on the surface of metal and is capable of blocking the entry of oxygen molecules and preventing rusting, so that the problem that theprinting machine is corroded is avoided; and the problems that the printing ink cleaning agent in the current market is not ideal enough, high in pollution and strong in corrosivity are solved.

Description

technical field [0001] The invention belongs to the technical field of ink cleaning agents, and in particular relates to a preparation method of an ink cleaning agent used for printing machines. Background technique [0002] An ink cleaning agent belongs to one of the products used in the technical field of ink. Ink is generally composed of pigments, binders, solvents and additives. These components are evenly mixed and rolled repeatedly to form a viscous colloidal fluid. Ink is widely used in various printings such as books, periodicals, packaging and decoration, and architectural decoration. Due to the strong adhesion and cohesiveness of the ink, when the hands of the printing workers are stained by the printing ink, the very fine pigments will enter the palm prints with the ink base material, and it is very difficult to clean. It is difficult to wash with soap and general detergents. , seriously disturbing and affecting the normal work of the workers. The main body of t...
