High-magnesium desulfurized gypsum paper-surface gypsum board and preparation method thereof
The invention provides a high-magnesium desulfurized gypsum plaster board and a preparation method thereof. The gypsum plaster board comprises a board core and surface protection paper on the outer side of the board core. The board core is prepared from, by mass, 100 parts of desulfurized gypsum raw materials, 60-75 parts of water, 0.5-10 parts of zeolite, 0.05-0.2 part of glass fibers, 0.2-1 partof retarder and 0.2-1 part of starch. The side, contacting with the board core, of the surface protection paper is coated with the zeolite. The preparation method of the board core comprises the following steps of: crushing the zeolite and desulfurized gypsum raw material, drying and grinding the zeolite and desulfurized gypsum raw material, and mixing the dried and ground zeolite and desulfurized gypsum raw material with the glass fibers to obtain a mixture; mixing the water, retarder and starch to prepare a mixed solution; uniformly mixing the mixed solution with the mixture to obtain gypsum slurry; and spraying the gypsum slurry on the surface protection paper sprayed with a mixed solution of an adsorption material and starch in advance, and carrying out molding, solidification, drying, lamination, edge sawing, edge sealing and packaging to obtain the gypsum plaster board.
本发明提供了一种高镁脱硫石膏纸面石膏板及其制备方法,所述纸面石膏板包括板芯以及板芯外侧的护面纸,板芯原料按质量份计包括:脱硫石膏生料100份、水60‑75份、沸石0.5‑10份、玻璃纤维0.05‑0.2份、缓凝剂0.2‑1份、淀粉0.2‑1份;所述护面纸与板芯接触的一侧涂覆有沸石。所述板芯的制备,包括将沸石与脱硫石膏生料破碎、烘干、磨细后与玻璃纤维混合,制得混合料;将水、缓凝剂和淀粉混合制成混合液;将混合液与混合料混合均匀制得石膏料浆;并将石膏料浆喷洒在预先喷洒有吸附材料和淀粉的混合溶液的护面纸上,经成型,凝固,干燥,合片,锯边,封边,包装,制得纸面石膏板。
