The invention relates to a compound containing polyhydric amino alcohols, a preparation method thereof, and an application as a concrete rust inhibitor. The compound containing polyhydric amino alcohols is used as a concrete rust inhibitor, which can improve the adsorption capacity with iron atoms and prevent rust inhibitors Volatilization and loss, improve corrosion resistance. The polyamino alcohol-containing compound has a structural formula (I), wherein R 1 is H, R 2 is -(CH 2 CH 2 NH) m H or -(CH 2 ) n NH 2 , m and n are integers from 2 to 6; or R 1 and R 2 are each independently -CH 3 , -CH 2 CH 3 , -CH 2 CH 2 CH 3 , -CH 2 CH 2 CH 2 CH 3 , -CH One of (CH 3 ) 2 , —CH 2 CH(CH 3 ) 2 , —CH(CH 2 ) 5 (cyclohexyl) or —C(CH 3 ) 2 CH 2 CH 3 . The polyhydric amino alcohol compound is obtained by reacting an epoxy derivative and an organic amine under the action of a catalyst. |
