| titleOfInvention | A kind of sulfonate series cement grinding aid raw material and preparation method thereof |
| abstract | The invention discloses a kind of sulfonate series cement grinding aid raw material and preparation method thereof, are related to the replacement and its preparation field of sulfonate series cement grinding aid raw material, and the preparation method of the sulfonate series cement grinding aid raw material is as follows：1. under alkaline condition, formalin and urea carry out addition reaction, polyhydroxy methylurea is generated；2. formaldehyde under alkaline condition, is added in into step 1. reaction product, neopelex carries out polycondensation reaction, obtained sulfonate based copolymer UFD；Above step 1. and 2. in, the alkaline condition is adds in alkaline solution, and in reaction process, the pH for controlling reaction is 10~12.A kind of UFD sulfonate based copolymers of the preparation method production of cement grinding aid raw material provided by the invention, there is good grinding aid enhancing effect in cement, stability is relatively good, production cost is less than triethanolamine, can partly instead of or replace the early strength agent that plays the role of in cement grinding aid of triethanolamine completely, this method is easy to operate, at low cost, safety is good and high income. |
