Abstract

The invention relates to the field of fine chemical engineering, in particular to a flame-retardant electronic cleaning agent and a preparation method thereof. According to the flame-retardant electronic cleaning agent and the preparation method thereof, the electronic cleaning agent is prepared and treated through a formula free of Freon-like matter, fluorochemicals are introduced in the preparation process, and the cleaning agent has certain flame-retardant ability; a fluorine-contained cosolvent is added, and the cleaning power of the cleaning agent can be further increased; and the cleaning agent has the characteristics that flame retarding is achieved, flash points are avoided, and the ODP (ozone-depleting potential) value is zero, and good compatibility with most plastic materials isachieved.

Description

technical field [0001] The invention relates to the field of fine chemicals, in particular to a flame-retardant electronic cleaning agent and a preparation method thereof. Background technique [0002] With the rapid development of electronic products in the direction of miniaturization, high density and high reliability, more and more pollutants are introduced into the electronic manufacturing process. If these pollutants are not removed in time, it will inevitably affect the process. smooth implementation or product quality and reliability. Therefore, in order to ensure the smooth progress of the electronic manufacturing process and ensure the quality and reliability of the manufactured products, it is necessary to introduce cleaning procedures and use cleaning agents in many links of process implementation. [0003] CN104152298A discloses a cleaning agent for precision electronics, which comprises 75-80 parts by mass of raw materials containing halogen compounds, 8-15 pa...
