Gypsum plaster board and manufacturing method thereof
The invention discloses a gypsum plaster board and a manufacturing method thereof. The gypsum plaster board comprises protection paper and a core veneer, wherein the core veneer of the gypsum plasterboard is prepared from the following components of desulfurized gypsum clinker, water, foaming agent, glass fiber and retarder; and a starch solution is sprayed to the one side, being in contact withthe core veneer, of the protection paper. The gypsum plaster board is manufactured by the following steps: weighing and uniformly mixing the desulfurized gypsum clinker and glass fiber to obtain a mixture; weighing and uniformly mixing the water, foaming agent and retarder to obtain a mixture; weighing modified starch, mixing the modified starch with the water to obtain a starch solution, heatingthe starch solution, or weighing pregelatinized starch, mixing the pregelatinized starch with the water for stirring to obtain the starch solution; adding the mixture into the mixed solution to obtaingypsum plaster; uniformly spraying the starch solution to the upper protection paper and the lower protection paper; overlapping the gypsum plaster and the protection papers for sticking and moldingto obtain a wet board; and overlapping and bonding the gypsum plaster and the protection paper for molding to obtain a wet board, and drying the wet board after the wet board is condensed to obtain the gypsum plaster board.
一种纸面石膏板及其制备方法。所述纸面石膏板包括护面纸和芯板，所述纸面石膏板芯板原料包括如下组分：脱硫石膏熟料、水、发泡剂、玻璃纤维和缓凝剂；所述护面纸与板芯接触的一面喷洒有淀粉溶液。纸面石膏板的制备步骤如下：称量脱硫石膏熟料和玻璃纤维并混合均匀，得到混合物；称量水、发泡剂和缓凝剂并混合均匀，得到混合液；称量改性淀粉，并将改性淀粉与水混合，得到淀粉溶液并加热，或者称量预糊化淀粉，并将预糊化淀粉与水混合，搅拌制成淀粉溶液；之后在混合液中加入混合物，制成石膏料浆；在上下护面纸上均匀喷洒淀粉溶液；将石膏料浆与护面纸搭接粘牢成型，制得湿板，待湿板凝固后经干燥后的湿板即为纸面石膏板。
