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.

A water-based anti-rust, degreasing and wax-removing cleaning agent and its preparation method and application
The invention provides a water-based rust-proofing, degreasing and wax removing cleaning agent and a preparation method and application thereof. The cleaning agent comprises a high molecular surfactant, diethanol amine oleic soap, alkylolamide phosphate 6503, diallyl succinimide T154, sodium tripolyphosphate, sodium metasilicate, a penetrant TA-2, zinc dialkyl dithiophosphate, polyethylene glycol 400 and deionized water. The cleaning agent is applicable to manufacturing of various metals; dirt such as polishing wax, grinding wax, grease and greasy dirt on the metal surface can be cleaned under normal temperature, instead of being cleaned under high temperature; the cleaning agent is low in use concentration, high in permeability, low in foam, high in wax removing efficiency, free from strong acid and sodium hydroxide, free from damage to a matrix, high in physicochemical stability, long in service life, free from APEO (alkylphenol ethoxylates) nonionic surfactant, green, nontoxic, and high in rust-proofing performance.
