The invention discloses a concrete rust inhibitor and a preparation method thereof. The rust inhibitor of the invention is a compound having the structure of 1-dihydroxyethylamino-3-alkylamino-2-propanol, which consists of two One-step reaction: first react epoxy derivatives and diethanolamine under the action of a catalyst, then react the product with organic amine, neutralize, distill and filter the obtained product, and the obtained liquid is this product. Invented rust inhibitor. The synthesis process of the invention is simple, and the prepared rust inhibitor has the advantages of high-efficiency rust resistance, environmental protection, good dispersibility, etc., and has no adverse effect on the performance of concrete. |
