Abstract

The invention provides a cleaning agent for an electronic element and a preparation method thereof. The cleaning agent is prepared from sodium dodecyl benzene sulfonate, polyethylene glycol, sodium metasilicate, sodium tripolyphosphate, isopropanol, sodium bicarbonate, nonylphenol polyoxyethylene ether, fatty alcohol-polyoxyethylene ether, N, N'-2-hydroxyethyl tridecyl amide, carboxymethyl cellulose sodium, coconut diethanolamide, 2-butoxyethanol, alcohol, triethanolamine, propylene glycol and deionized water. The preparation method comprises the steps of adding sodium dodecyl benzene sulfonate, polyethylene glycol, sodium metasilicate, sodium tripolyphosphate, sodium bicarbonate and carboxymethyl cellulose sodium to deionized water to obtain a mixed solution I; heating alcohol, isopropanol and propylene glycol until reaching azeotropy to obtain a mixture; adding nonylphenol polyoxyethylene ether, fatty alcohol-polyoxyethylene ether and 2-butoxyethanol to obtain a mixed solution II; mixing the mixed solution I and the mixed solution II; adding the rest components; heating to obtain the cleaning agent. The cleaning agent is small in foam, free of corrosion, little to be volatilized, few in residues and low in viscosity.

Description

technical field [0001] The invention belongs to the technical field of cleaning agents, and in particular relates to a cleaning agent for electronic components and a preparation method thereof. Background technique [0002] In the production process of electronic components manufactured by the electronics industry, it is an essential process to use cleaning agents to clean the components, and most of the cleaning agents used include Freon, which is a substance that destroys the ozone layer of the atmosphere. , According to the internationally signed Montreal Protocol, each signatory country should gradually phase out chlorofluorocarbons such as Freon. This is a task and challenge for the electronics industry, so it is necessary to choose a suitable alternative cleaning agent and adopt a corresponding production process. [0003] The earth is the home on which human beings depend for survival, and protecting the environment is to protect human beings themselves. The hole in...
