| titleOfInvention | A kind of efficient and stable preparation method of gypsum retarder |
| abstract | The invention discloses a preparation method of an efficient and stable gypsum retarder. The gypsum retarder is obtained by the synthesis reaction of an acid anhydride containing benzene and an amine substance under the action of an alkaline catalyst, and the retarder obtained by the preparation method is used in Gypsum products can effectively prolong the setting time of gypsum. Compared with other types of gypsum retarders, the gypsum retarder of the present invention has remarkable "low-mixing and high-efficiency" performance, and the setting retardation time is stably and continuously controlled. The effect of the dosage is remarkable, and the retardation time rises steadily and continuously with the increase of the dosage, which perfectly solves the problem of “low dosage is inefficient, and high dosage is easy to overdose” for most of the current retarders, which brings great benefits to the adjustment of the setting time of plaster of Paris. Great convenience, this synthesis process is an organic synthesis process under the protection of high temperature and high pressure and inert gas, which greatly improves the stability and adaptability of gypsum retarder under different conditions, and can be widely used in different gypsum or different gypsum products. time adjustment. |
