Abstract

The invention discloses a water-based LED (light emitting diode) chip cleaning agent, prepared from the following components of alkylolamide polyoxyethylene ether, polyoxyethylene sorbitan fatty acid ester, an emulsifier, an organic solvent, tetrahydrofurfuryl alcohol, trifluoroethanol, tripropylene glycol monomethyl ether, 2-(2'-hydroxylphenyl)benzoimidazole, sodium cumenesulfonate, a dispersant, a corrosion inhibitor and deionized water. The cleaning agent provided by the invention has the advantages that the effects of high cleaning efficiency, strong detergency, good safety performance, freeness from environmental pollution, energy saving and low washing cost are achieved; an LED is not damaged in a washing process; a protective film can be formed on the surface of a chip through the cleaning agent, so that air is isolated, and the chip is prevented from being corroded by moisture and other molecules in the air, therefore the effect of oxidation resistance is achieved, and a next production process is conveniently performed.

Description

technical field [0001] The invention relates to a cleaning agent, in particular to a water-based LED chip cleaning agent. 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 the ozone layer caused by large-scale industrial production has attract...
