Beschreibung
Zusammenfassung:	A preparation method of an amino silane coupling agent comprises the following steps: liquid-liquid mixing a raw material A and a raw material B according to a molar ratio of 1: (1-1.2), discharging the obtained premixed liquid into a solvent system for reaction to obtain a reaction product, the solvent system is a mixture of a solvent and a catalyst, the raw material B is ethidene diamine, and the raw material B is a silane coupling agent; the raw material A is 3-chloropropyltrimethoxysilane or 3-chloropropyldimethoxymethylsilane, when the raw material A is 3-chloropropyltrimethoxysilane, the reaction temperature is 125-130 DEG C, when the raw material A is 3-chloropropyldimethoxymethylsilane, the reaction temperature is 95-100 DEG C, and the liquid-liquid mixing temperature is lower than the boiling point temperature of the raw material A and the boiling point temperature of the raw material B. According to the design, the purity and the yield of a target product in the reaction liquid can be improved, and
