Environment-friendly type water-based cleaning agent and application

Abstract

The invention relates to the technical field of cleaning agents, in particular to an environment-friendly type water-based cleaning agent and an application. The cleaning agent comprises components in percentage by mass as follows: 6%-12% of an ether ester type main solvent, 8%-16% of a printing ink latent solvent, 1%-5% of a plasticizer, 0.5%-3% of a non-ionic surfactant, 1%-5% of an anionic surfactant and 55%-85% of deionized water. The raw materials of the cleaning agent adopt components such as the organic solvents, the latent solvent, the surfactants and the like, the prepared environment-friendly type water-based cleaning agent does not contain halogens and acidic and alkaline substances and has the characteristics of good cleaning capacity, neutral and environment-friendly performance, safety in use, avoidance of flash points and the like, and moreover, the environment-friendly type water-based cleaning agent is non-corrosive to metals such as an aluminum alloy of a screen frame and the like and is suitable for cleaning non-cured printing ink.

Description

technical field [0001] The invention relates to the technical field of cleaning agents, in particular to an environment-friendly water-based cleaning agent and its application. Background technique [0002] Ink is the raw material used in the printing of text, patterns, logos, etc. on the outer packaging of various products. With the continuous development of industry and the continuous improvement of people's quality of life, there are more and more products with printed characters, brands, patterns and logos, and the requirements for these printings are getting higher and higher. [0003] At present, most of these printings use screen printing. In the process of operation, inks of different colors need to be replaced frequently, and different printing screens need to be replaced at the same time. The replaced screens need to be cleaned as soon as possible, otherwise the printing screen will be scrapped. Therefore, there is an inevitable market demand for cleaning the resi...

Problems solved by technology

[0005] At present, the cleaning of printing inks on the market mainly includes the following three types of cleaning agents: 1) Solvent-based cleaning agents. The components of this type of cleaning agent mainly use petroleum solvents similar to gasoline and kerosene. Inflammable and explosive safety hazards, so this type of cleaning agent is gradually eliminated; 2) Emulsion ink cleaning agent, this type of cleaning agent is a mixture of gasoline and other flammable organic solvents and water by adding composite surfactants and other additives However, the cleaning agent prepared by this method is prone to demulsification and causes unstable performance; 3) water-based ink cleaning agent, this type of cleaning agent uses water as the main component, has less environmental pollution, low price, and is completely non-flammable , safe use and other advantages

However, there are also many disadvantages in the current third class of water-based cleaning agents, such as a water-based ink cleaning agent with ester and organic acid as the main components disclosed in Chinese patent 02102265.8, the presence of ester and acid in this cleaning agent , will lead to unstable performance, and is corrosive to metal printing equipment such as carbon steel and aluminum alloy; Chinese patent 201010100923.6 discloses a water-based ink cleaning agent, whose main components are phosphate ester salt, inorganic alkali and surfactant, Among them, the penetrating agent in the surfactant adopts alkylphenol polyoxyethylene ether, and alkylphenol polyoxyethylene ether is a chemical restricted by REACH regulations, and its biodegradability is not good, and it will pollute the environment when discharged into nature. Similarly, phosphorus in phosphate salt will also cause phosphorus in water and is not environmentally friendly, and because most of the screens are made of aluminum alloy frames, inorganic alkalis are also corrosive to aluminum and aluminum alloy materials, so this This type of cleaning agent is no longer applicable under the situation of continuous upgrading of environmental protection requirements
