The invention relates to a gypsum board capable of being bent at will and a preparation method thereof. When used, the gypsum board capable of being bent randomly can be bent randomly after being soaked in water for two or three minutes. The preparation method of the gypsum board capable of being bent at will comprises the following steps: (1) shredding, soaking and pulping wood pulp fibers; (2) adding water into the calcined gypsum, and adding an additive to obtain two-water gypsum slurry; (3) adding the treated wood pulp into the gypsum slurry in proportion; (4) forming (two forming modes of a beater-addition method and a slurry flowing method are generally used); and (5) carrying out steam curing to prepare the gypsum board capable of being bent at will.
本发明涉及一种可任意弯曲的石膏板及其制备方法。可任意弯曲的石膏板使用时在水中泡两三分钟即可任意弯曲形状。可任意弯曲的石膏板的制备方法，包括如下步骤：(1)把木浆纤维碎纸、浸泡、磨浆；(2)熟石膏加水、加添加剂，变成二水生石膏浆；(3)将处理好的木浆按比例加入生石膏浆中；(4)经成型（一般用抄取法和流浆法两种成型方式）;(5)蒸汽养护而制成可任意弯曲的石膏板。
