Technical Field

The invention relates to the technical field of screen printing plate cleaning, in particular to an environment-friendly cleaning agent for a screen printing plate and a preparation method thereof.

Background

In the printed circuit board industry, screen printing is used in the processes of solder mask and text, and the screen printing is different due to different manufactured circuit board products, so the screen is required to be cleaned for repeated use. The traditional screen printing plate cleaning agent is used for dissolving printing ink on a screen printing plate in a dihydric alcohol organic matter by soaking alcohol ether substances so as to achieve the purpose of cleaning. However, the cleaning agent has volatility, so that operators are easy to hurt the bodies of the printing rooms when operating the printing rooms in a sealed environment, and the environmental protection safety is poor.

Disclosure of Invention

In order to solve the problems in the prior art, the invention provides an environment-friendly cleaning agent for a screen printing plate, which has the advantages of excellent cleaning effect on the screen printing plate, small volatilization amount, low harm to a human body, environmental protection and safety.

In order to achieve the purpose, the invention adopts the following technical scheme:

the environment-friendly cleaning agent for the screen printing plate comprises the following components in parts by weight:

furthermore, the dihydric alcohol is one of ethylene glycol, propylene glycol, dipropylene glycol and isopropanol, and the concentrated substances can be used for providing a dissolving environment for the ink and helping the ink on the screen printing plate to dissolve.

Furthermore, the cosolvent is propylene glycol methyl ether acetate which is one of solvent components of the printing ink, so that the ink dissolution can be accelerated, and the screen printing plate cleaning efficiency can be improved.

Furthermore, the dissolving agent is one or more of dimethyl oxalate, dimethyl glutarate and dimethyl adipate, and the substances are the main components of the solvent of the printing ink, so that the printing ink can be wetted, emulsified, dispersed, compatibilized and the like, and can be quickly stripped from the screen printing plate and dispersed into the cleaning agent, and finally, the cleaning effect is achieved.

Furthermore, the regulator is carbonate, and carbonate substances can provide a weak-alkali cleaning environment for the screen printing plate so as to accelerate stripping of the ink and accelerate cleaning efficiency.

According to the embodiment of the second aspect of the application, the preparation method of the environment-friendly cleaning agent for the screen printing plate comprises the following steps: sequentially adding the dihydric alcohol and the cosolvent into a stirring cylinder, and stirring for 30min until the mixture is uniformly mixed; and then adding a dissolving agent and a regulator into the stirring cylinder, and stirring for 30min to fully mix the materials in the stirring cylinder to obtain the environment-friendly cleaning agent.

Compared with the prior art, the invention has the beneficial technical effects that: the environment-friendly cleaning agent for the screen printing plate adopts esters with high boiling point and low volatility as main components, reduces the volatility and the irritation of the cleaning agent, and is environment-friendly and safe; the printing plate does not contain strong acid and strong base, so that the printing plate is not damaged, the service life of the printing plate is prolonged, and the use cost is reduced; in addition, the cleaning agent does not contain substances such as nitrogen, benzene and the like, reduces the wastewater treatment cost and is safer to use.
