Abstract

The invention discloses a gemini surfactant containing a rosin structure and a preparation method thereof, wherein the method comprises the following steps: (1) adding cyanuric chloride and dehydroabietylamine into an acetone solvent, adding a catalyst, carrying out reflux reaction for 4-10 hours at the temperature of 60-70 DEG C, removing the acetone solvent, and purifying to obtain a product 2-dehydroabietylamine-4,6-dichloro-1,3,5-triazine; and (2) adding the 2-dehydroabietylamine-4,6-dichloro-1,3,5-triazine obtained in the step (1) and long-chain tertiary amine into a reaction container, reacting for 5-8 hours at the temperature of 100-110 DEG C by taking methylbenzene as a solvent, carrying out reduced pressure distillation to remove the methylbenzene solvent, and carrying out vacuum drying to obtain a finished product of the gemini surfactant containing the rosin structure. The prepared gemini surfactant containing the rosin structure contains the rosin structure, has higher affinity with the rosin substance, can better emulsify rosin pollutants, and also has industrialization value.

Description

technical field [0001] The invention relates to the field of surfactant preparation, in particular to a gemini surfactant containing a rosin structure and a preparation method thereof. Background technique [0002] With the rapid development of electronic products in the direction of miniaturization, high density and high precision, more and more impurities will be introduced in the electronic manufacturing industry. During the soldering process of the assembled circuit board, in order to ensure the reliability of the soldering, a highly active flux is used. However, the residual flux will cause corrosion to the circuit board and components, resulting in leakage, short circuit and other problems. At the same time, hand sweat, fingerprints and dust impurities in the air during the assembly process will affect the quality of the circuit board. In order to ensure the stability of the quality of the circuit board, it is necessary to introduce a cleaning process in multiple link...
