Application of alkyl quaternary ammonium salt as gypsum coagulant and composite gypsum coagulant
The invention relates to the technical field of gypsum dry-mixed mortar, and provides application of alkyl quaternary ammonium salt as a gypsum coagulant and a composite gypsum coagulant. The alkyl quaternary ammonium salt is used as a gypsum coagulant, so that the initial setting time and the final setting time of the gypsum mortar can be effectively controlled; furthermore, the alkyl quaternary ammonium salt and the inorganic gypsum coagulant are matched for use, so that a synergistic effect can be achieved, the initial setting time and the final setting time of the gypsum mortar are accurately controlled, the qualification rate of the gypsum mortar is greatly increased, the use amount of industrial gypsum such as citric gypsum and fluorgypsum in the building dry-mixed mortar is increased, waste is really turned into wealth, and the cost is reduced. And the use amount of the inorganic coagulant in the gypsum-based dry-mixed mortar can be reduced.
本发明涉及石膏干粉砂浆技术领域，提供了烷基季铵盐作为石膏促凝剂的应用以及一种复合石膏促凝剂。本发明将烷基季铵盐作为石膏促凝剂使用，能够有效控制石膏砂浆的初终凝时间；进一步的，本发明将烷基季铵盐和无机石膏促凝剂配合使用，能够起到协同效果，准确控制石膏砂浆的初终凝时间，大大提升石膏砂浆的合格率，提高柠檬酸石膏、氟石膏等工业石膏在建筑干粉砂浆中的使用量，真正做到变废为宝，并且还能降低石膏基干粉砂浆中无机促凝剂的用量。
