A kind of preparation method of hydrotalcite rust inhibitor based on single point control pH value |
| abstract |
A method for preparing a hydrotalcite rust inhibitor based on single-point control of pH value, comprising the following steps: (1) 12.49 parts by mass of magnesium nitrate hexahydrate are dissolved in 122 parts by mass of water to obtain solution A; 1-2 parts by mass of meta-aluminum Sodium and 2.72-5.04 parts of mass sodium hydroxide are dissolved in 122 parts of mass of water to obtain solution B; (2) maintaining a certain temperature, introducing nitrogen gas and continuously stirring solution A into solution B, and controlling the dropwise addition The pH of the mixed solution C is 11～13.5; (3) continue stirring for a certain period of time, and centrifugally wash the obtained precipitation product; (4) vacuum dry the precipitation product after centrifugal washing at 60° C. for 36 to 48 hours; ( 5) Grinding and sieving the dried product to obtain a hydrotalcite rust inhibitor. |
