Formula of high-hardness pouring type gypsum template
The invention relates to a high-hardness pouring type gypsum template formula in the technical field of gypsum. The high-hardness pouring type gypsum template formula comprises the following materials in parts by weight: 1 part of 42.5 sulfur aluminum cement; 1 part of common river sand; 0.0016 part of a polycarboxylic acid water reducing agent; 0.128 part of a pure acrylic polymer emulsion; 0.00128 parts of a liquid defoaming agent; and 0-0.14 part of recycled fiber. According to the cement-based material, different types of recycled fibers are doped, the fibers have crack resistance and can delay cracking of the cement-based material and prevent microcrack propagation, the toughness of the cement-based material can be improved through the four fibers, the toughness and bending resistance of the cement-based material can be improved through the recycled fibers A and the recycled fibers B, the fiber A is greatly improved, and the fiber B is greatly improved. The recycled fiber O and the recycled fiber C have a common effect of improving the bending resistance of the cement-based material, but can improve the toughness of the cement-based material, and the optimal mixing amounts of the recycled fiber O, the recycled fiber A, the recycled fiber B and the recycled fiber C are 4%, 4%, 8% and 4% respectively.
本发明涉及石膏技术领域的一种高硬度浇筑式石膏模板配方，所述高硬度浇筑式石膏模板配方包括以下重量份的物料：42.5硫铝水泥1份；普通河砂1份；聚羧酸减水剂0.0016份；纯丙聚合物乳液0.128份；液体消泡剂0.00128份；回收纤维0‑0.14份。本发明中掺入不同种类的回收纤维，纤维具有阻裂性，能够延缓水泥基材料的开裂，并阻止微裂纹扩展，四种纤维能够提高水泥基材料的韧性，回收纤维A、回收纤维B均能够提高水泥基材料的韧性、抗弯性能，且纤维A提升幅度较大，回收纤维O、回收纤维C对提升水泥基材料抗弯性能效果一般，但均能够提高水泥基材料的韧性，回收纤维O、回收纤维A、回收纤维B、回收纤维C最佳掺量分别为4％、4％、8％、4％。
