Composite gypsum board and preparation method thereof
The invention discloses a gypsum board. The gypsum board is prepared from 85 to 95 parts by weight of gypsum powder, 0 to 10 parts by weight of zeolite, 1 to 5 parts by weight of polyacrylic emulsionand 0.3 to 1.0 part by weight of starch. The invention further discloses a composite gypsum board. The composite gypsum board comprises the gypsum board, paint and primer, the amount of the gypsum board is 6 kg/m < 2 >-7 kg/m < 2 >, the amount of the paint is 0.2 kg/m < 2 >-0.5 kg/m < 2 >, and the amount of the primer is 0.1 kg/m < 2 >-0.3 kg/m < 2 >. The invention further provides a preparation method of the composite gypsum board. Compared with a common gypsum board, the composite gypsum board has the advantages that the heating rate is lower than that of the common gypsum board, the fire-resistant time is obviously prolonged, the surface water absorption rate is obviously reduced, and the antibacterial effect is achieved.
本申请公开一种石膏板，所述石膏板包括85‑95重量份的石膏粉，0‑10重量份的沸石，1‑5重量份的聚丙烯酸乳液，0.3‑1.0重量份的淀粉。本申请还公开一种复合石膏板，所述复合石膏板包括所述石膏板、涂料和底漆，其中，所述石膏板的量为6kg/m‑7kg/m，所述涂料的量为0.2kg/m‑0.5kg/m，所述底漆的量为0.1kg/m‑0.3kg/m。本申请还提供所述复合石膏板的制备方法。相比于普通石膏板，本申请的复合石膏板升温速率低于普通石膏板，耐火时间明显延长，表面吸水率明显降低并具有抑菌作用。
