Lightweight high-toughness phosphorus II type anhydrous gypsum-based wallboard and preparation method thereof
The invention relates to the technical field of cementing materials, and discloses a lightweight high-toughness phosphorus type II anhydrous gypsum-based wallboard and a preparation method thereof.The lightweight high-toughness phosphorus type II anhydrous gypsum-based wallboard is prepared from, by weight, 100 parts of phosphorus type II anhydrous gypsum, 10-30 parts of building gypsum, 3-9 parts of cement, 6-12 parts of slag, 30-45 parts of water, 25-50 parts of glass beads, 0.1-0.5 part of basalt fibers, 0.1-0.5 part of polyvinyl alcohol fibers and 0.3-1.5 parts of gypsum whiskers. The coating is prepared from the following components in parts by weight: 0.1 to 0.6 part of nano silicon dioxide, 0.2 to 0.7 part of a silane coupling agent, 0.3 to 1.0 part of an exciting agent, 0.1 to 0.5 part of a water reducing agent and 0.1 to 0.7 part of an adhesive. The light high-strength phosphorus II type anhydrous gypsum-based cementing material is prepared by adopting physical-chemical composite excitation, hardened body microstructure regulation and control and other methods; on the basis of the synergistic effect of hybrid fibers and the superposed physical-chemical adsorption effect, the interface transition area between the fibers and a matrix is improved, the cohesive force is increased, and the force transfer path is optimized, so that the fiber bridging effect is fully exerted, and the toughness of the wallboard is greatly improved.
本发明涉及胶凝材料技术领域，公开了一种轻质高韧性磷Ⅱ型无水石膏基墙板及其制备方法，其墙板的各组分按重量份数计，包括：磷Ⅱ型无水石膏100份，建筑石膏10～30份，水泥3～9份，矿渣6～12份，水30～45份，玻化微珠25～50份，玄武岩纤维0.1～0.5份，聚乙烯醇纤维0.1～0.5份，石膏晶须0.3～1.5份，纳米二氧化硅0.1～0.6份，硅烷偶联剂0.2～0.7份，激发剂0.3～1.0份，减水剂0.1～0.5份，胶粘剂0.1～0.7份。本发明采用物理‑化学复合激发、调控硬化体微结构等方法，制备出轻质高强型磷Ⅱ型无水石膏基胶结材；基于混杂纤维的协同效应，叠加物理‑化学吸附作用，以改善纤维与基体之间界面过渡区，增加黏结力，并优化传力路径，从而充分发挥纤维桥接效应，大幅提高墙板韧性。
