Fiber reinforced gypsum composite material and gypsum mold box
The invention belongs to the technical field of building materials, and particularly relates to a fiber reinforced gypsum composite material and a gypsum mold box. The invention provides a fiber reinforced gypsum composite material. The fiber reinforced gypsum composite material is prepared from the following components in parts by mass: 100 parts of phosphogypsum, 45 to 60 parts of water, 0.5 to 3.5 parts of calcium oxide, 0.2 to 0.6 part of polypropylene fiber, 0.1 to 0.3 part of polyvinyl alcohol fiber, 0.1 to 0.6 part of polyphosphate, 0.2 to 0.6 part of silane coupling agent, 0.1 to 0.3 part of latex and 0.1 to 0.5 part of water reducing agent. According to the fiber-reinforced gypsum composite material provided by the invention, the polypropylene fibers and the polyvinyl alcohol fibers can optimize a force transfer path through a synergistic effect, so that a gypsum mold box prepared from the fiber-reinforced gypsum composite material provided by the invention has good cracking resistance and breakage resistance.
本发明属于建筑材料技术领域，具体涉及一种纤维增强石膏复合材料、一种石膏模盒。本发明提供了一种纤维增强石膏复合材料，包括以下质量份数的组分：磷石膏100份、水45～60份、氧化钙0.5～3.5份、聚丙烯纤维0.2～0.6份、聚乙烯醇纤维0.1～0.3份、多聚磷酸盐0.1～0.6份、硅烷偶联剂0.2～0.6份、乳胶0.1～0.3份和减水剂0.1～0.5份。在本发明中，聚丙烯纤维和聚乙烯醇纤维通过协同作用，能够优化传力路径，使得由本发明提供的纤维增强石膏复合材料制备得到的石膏模盒具有良好的抗开裂性能和抗破损性能。
