The invention discloses a toughened compression-resistant gypsum batten and a preparation method thereof.The gypsum batten is prepared from phosphogypsum, light calcium carbonate, semi-hydrated phosphogypsum, modified diatomite, modified elastomer particles, composite fibers, a retarder, a water reducing agent and water. The preparation method of the gypsum batten comprises the following steps that S1, the modified diatomite is prepared; the preparation method comprises the following steps: S1, preparing phosphogypsum, S2, preparing modified elastic particles, S3, preparing composite fibers, S4, stirring the phosphogypsum, light calcium carbonate, semi-hydrated phosphogypsum, the modified diatomite, the modified elastomer particles, the composite fibers, a retarder, a water reducing agent and water into uniform mixed slurry, pouring the mixed slurry into a mold, and carrying out extrusion molding, solidification, cutting, drying and edge sawing to obtain the toughened compression-resistant gypsum batten. Through filling and adsorption effects of the light calcium carbonate, the semi-hydrated phosphogypsum and the modified diatomite and a three-dimensional network structure of the composite fibers, the compactness and the compression resistance of the gypsum batten are jointly improved.
本发明公开了一种增韧抗压石膏条板及其制备方法，石膏条板在组成包括以下组分：磷石膏、轻质碳酸钙、半水磷石膏、改性硅藻土、改性弹性体颗粒、复合纤维、缓凝剂、减水剂、水，石膏条板的制备方法包括以下步骤：S1.制备改性硅藻土，S2.制备改性弹性颗粒，S3.制备复合纤维，S4.将所述磷石膏、轻质碳酸钙、半水磷石膏、改性硅藻土、改性弹性体颗粒、复合纤维、缓凝剂、减水剂、水，搅拌成为均匀的混合浆体，将混合浆体浇筑进入模具内，经挤压成型、凝固、切断、干燥、锯边，得到增韧抗压石膏条板；本发明通过轻质碳酸钙、半水磷石膏和改性硅藻土的填充和吸附作用，以及复合纤维的三维网络结构，共同提高了石膏条板的密实度和抗压性能。
