The invention discloses a gypsum plaster board coagulation accelerator and a preparation method thereof, and relates to the technical field of gypsum board coagulation accelerators. The invention provides a setting accelerator for a gypsum plaster board. The setting accelerator is prepared from the following components in parts by weight: 92-96 parts of gypsum powder, 1-3 parts of attapulgite and 3-5 parts of sugar. The preparation method of the coagulant comprises the following steps: S1, grinding gypsum until the particle size is less than 0.01 mm to obtain gypsum powder; s2, attapulgite is added into sugar, heating and uniform stirring are performed, and a mixture is obtained; s3, adding the mixture prepared in the step S2 into the gypsum powder prepared in the step S1, and grinding and stirring; and then drying to obtain the coagulant. The sugar can rapidly grow crystals and reduce the initial setting time, and the attapulgite has high adsorption capacity, so that the sugar can be distributed more uniformly, the crystal growth is accelerated, and the final setting time is reduced; the attapulgite enables the combination of the sugar and the gypsum to be tighter, so that the fracture load of the gypsum plaster board is improved.
本申请公开了一种纸面石膏板促凝剂及其制备方法，涉及石膏板促凝剂技术领域。本申请提供的一种纸面石膏板促凝剂，由以下按重量份数计的组分制成：石膏粉92～96份、凹凸棒土1～3份以及糖3～5份。促凝剂的制备方法，包括以下步骤：S1、将生石膏研磨至粒径小于0.01mm，得到石膏粉；S2、将凹凸棒土加入至糖中，并加热搅拌均匀，得到混合物；S3、将S2中制备的混合物加入至S1中制备的石膏粉中，进行研磨搅拌；再进行烘干，得到促凝剂。糖能够使晶体快速增长，降低初凝时间，凹凸棒土的高吸附能力，能够使糖能够分布的更均匀，加速晶体成长，降低终凝时间；凹凸棒土使糖与生石膏结合更紧密，提高纸面石膏板的断裂荷载。
