Abstract

The invention discloses a halogen free environment-friendly cleaning agent, consisting of the following materials by weight: 5-10 percent of C9-C12 isoparaffin, 1-8 percent of degreasing agent, 5-12 percent of binary alcohol ether, 1-5 percent of non-ionic surfactant and the balance alkyl alcohol. The invention has the beneficial effects that the halogen free environment-friendly cleaning agent has excellent cleaning capability of cleaning the residual soldering flux on circuit boards in the electronics industry, has rapid cleaning speed, moderate volatilization speed and non-toxicity, is halogen free, has non pungent smell and no harm to the human body, and the cleaned board can not become white and has no water mark. The invention has no pollution to the atmospheric environment, is a cleaning agent with high cleaning capability and high environment protection.

Description

technical field [0001] The invention relates to an industrial cleaning agent, in particular to a halogen-free and environment-friendly cleaning agent suitable for cleaning residues on board surfaces and component surfaces of electronic products after welding. Background technique [0002] With the rapid development of the electronics industry, traditional cleaning agents contain ingredients that have a damaging effect on the environment, and the industrial cleaning agent industry is facing more and more stringent policy requirements. The most critical thing is that in order to protect the environment, ODS cleaning agents will be completely eliminated. In the cleaning industry, ODS refers to three cleaning agents: CFC-113, TCA, and CTC (carbon tetrachloride). In civilian cleaning fields such as precision industrial cleaning and clothes dry cleaning, the use of ODS cleaning agents and cleaning equipment is very common, involving almost all industrial fields. At present, halo...
