Mist, chemical attack, dust, vibration etc. cause wiring board to break down the problems such as generating mildew to wiring board, corrode.Three proofings
Paint is a kind of coating material of special formulation, by the surface of three-proofing coating coating assist side, forms the protective film of layer of transparent, protects
Cuticula protection circuit plate can escape injury under the environment such as humidity, smog, chemical attack, Gao Chen, vibration, improve wiring board
Service life, increase the safety coefficient of entire electronic component.
Existing three-proofing coating cleaning agent is generally used for the removal of coating for metal surfaces, and product is single, to three-proofing coating
Removal effect it is also relatively general, such as a kind of Chinese patent (CN108239433A) aqua type UV three-proofing coating cleaning agent proposed and its
Preparation method is mainly made into using a large amount of fatty alcohol polyoxyethylene ether, D- limonene and deionized water.Although more ring
It protects, safety, but it is poor for the cleaning ability of three-proofing coating, the relatively thin three-proofing coating of paint layer can only be removed.
Summary of the invention
The technical problem to be solved by the present invention is to overcome prior art disadvantage, provide a kind of three-proofing coating cleaning agent and its system
Preparation Method further enriches three-proofing coating cleaning agent type in the market.
In order to solve the above technical problems, technical solution provided by the invention are as follows: a kind of three-proofing coating cleaning agent, cleaning agent formula
Middle each component is according to parts by weight: 40~60 parts of methylene chloride, 20~30 parts of N-Methyl pyrrolidone, and higher boiling alcohol ether 10~30
Part, 1~3 part of bleeding agent, 2~5 parts of volatilization inhibitor, 2~5 parts of activator.
As an improvement, the higher boiling alcohol ether is dipropylene, dipropylene glycol methyl ether, dipropylene glycol propyl ether, the third two
The combination of one or more of alcohol butyl ether.
As an improvement, the bleeding agent is one of fatty alcohol polyoxyethylene ether JFC-E, JFC-U or JFC-2.
As an improvement, the volatilization inhibitor is atoleine.
As an improvement, the activator is phenol, ethylene glycol or isopropanol.
A kind of three-proofing coating cleaning agent preparation method, comprising the following steps:
S1 sequentially adds N-Methyl pyrrolidone, higher boiling alcohol ether, bleeding agent, volatilization inhibitor, activation into reaction kettle
Agent and methylene chloride, speed of agitator are 500~1000r/min, and mixing time is 10~15min；
S2, after being uniformly dispersed, standing is cooled to room temperature, and obtains three-proofing coating cleaning agent.
As an improvement, after the completion of cleaning agent preparation, at room temperature, article to be cleaned is immersed in 1 in cleaning agent~
10min then takes out, if surface can be brushed 10~20 times repeatedly there are also adhering to hairbrush.
The present invention has the advantage that (1) three-proofing coating cleaning agent prepared by the present invention is heavy duty detergent cleaning agent, it can be few
In the case where measuring use, the three-proofing coating of device surface is quickly sloughed.
