Water-base ink cleaning agent

Abstract

The invention discloses a water-base ink cleaning agent, which comprises the following components by weight percent: 3-12 percent of phosphate salt, 1-5 percent of alkali inorganic matter, 0-3 percent of cosolvent, 0.05-3 percent of penetrating agent, 0.1-4 percent of metal protecting agent and remaining percent of water. The cleaning agent has specially strong removal effect on slightly-dissolvable cured ink adhered onto ink printing devices and has protective function on the ink printing devices; the cleaning agent contains no inflammable and explosive component and transparent solution is obtained when the cleaning agent is mixed with water in any proportion; and the use of the cleaning agent is safe, no impact is caused to the human health and no environmental production is caused.

Description

technical field [0001] The invention belongs to the field of fine chemicals, and in particular relates to a water-soluble cleaning agent for printing ink. Background technique [0002] Ink is often used in various product packaging and text printing. In recent years, with the popularization of color printing technology in my country's printing industry, ink types of different colors must be replaced frequently during the ink printing process. Therefore, the residual ink cleaning process of printing equipment is an important guarantee for printing high-quality printed matter. [0003] At present, ink cleaning agents on the market are divided into three categories: (1) traditional gasoline and kerosene cleaning agents. Although this type of cleaning agent has a good cleaning effect, it has potential safety hazards of flammability and explosion, so it is gradually eliminated. (2) Emulsion ink cleaning agent. This kind of cleaning agent is made by adding complex surfactants a...

Problems solved by technology

But still there are many drawbacks in water-based ink cleaning agent at present, all provide a kind of water-soluble ink cleaning agent as Chinese patent 03119639.X and Chinese patent 02149620.X, main component is butyl cellosolve (ethylene glycol butyl ether), N- Methylpyrrolidone, of which butyl cellosolve is highly volatile and has a strong pungent odor during use; long-term exposure to N-methylpyrrolidone can lead to chronic poisoning of human internal organs. Therefore, this type of water-based ink cleaning agent is inconvenient to operate, The problem of endangering human health; as Chinese patent 02102265.8 discloses a kind of water-based ink cleaning agent with ester and organic acid as main components, the co-existence of esters and acids in this cleaning agent will lead to unstable performance, and to Carbon steel and aluminum alloy metal printing equipment have corrosion problems; such as Chinese patent 200710177421.1 and Chinese patent 200810122550.5 disclose a water-based ink cleaning agent, whose active ingredients are surfactant substances, although the performance is mild, the corrosion to equipment is low , but the cleaning effect is not ideal
