Environment-friendly circuit board cleaning agent and preparation method thereof

Abstract

The invention provides an environment-friendly circuit board cleaning agent. The cleaning agent is prepared from the following raw materials in parts by weight: 2-4 parts of sodium citrate, 5-10 parts of sodium laureth sulfate, 2-3 parts of coconut diethanolamide, 30-40 parts of ethanol, 4-5 parts of polyethylene glycol, 2-3 parts of petroleum sodium sulfonate, 2-3 parts of lignosulfonate, 4-5 parts of auxiliary and 100-120 parts of deionized water. The cleaning agent has the beneficial effects that the cleaning agent does not endanger the health of workers, is environment-friendly, non-combustible and non-explosive and has good safety because of using water and various low-toxicity reagents, is weakly acidic, enables the compatibility effects of various surfactants to be good, greatly improves the decontamination effect and the production efficiency, and reduces the cost; the auxiliary can form a protective film on the surface of the circuit board to isolate air to prevent water and other molecules in the air from corroding the circuit board; the cleaning agent is resistant to oxidation, prevents short circuit and is convenient for operation of the next preparation process.

Description

technical field

[0001] The invention relates to the field of cleaning agents, in particular to an environment-friendly circuit board cleaning agent and a preparation method thereof. Background technique

[0002] With the rapid development of integrated circuits, the volume of circuit boards is getting smaller and smaller, and electronic components are getting smaller and denser. If the dirt and dust inside are not cleaned during the production process, it may cause problems such as short circuit and corrosion, which will affect the normal operation of the circuit board. At present, most circuit board cleaners are made of organic substances, which have good cleaning effect and are not easy to cause problems such as short circuit and corrosion. However, organic compounds are not only expensive, but also pollute the environment, destroy the ozone layer, and are harmful to human health. There are also a few water-based cleaning agents, but the cleaning effect is limited and the...
