High-strength hydrogel plaster mold and preparation method thereof
The invention provides a high-strength hydrogel plaster mold and a preparation method thereof, and relates to the technical field of plaster molds. The high-strength hydrogel plaster mold is prepared by adding a small amount of polymer gel monomer and polymerization initiator, and simultaneously adding a small amount of polycarboxylate superplasticizer and phosphate defoaming agent. Even under a high water-gypsum ratio, the gypsum mold provided by the invention still has relatively high strength. The cost of gypsum raw materials is remarkably reduced, meanwhile, the water absorption rate of a gypsum mold is guaranteed, and the use frequency of the gypsum mold is increased. Meanwhile, the gypsum mold is cheap and easily available in raw materials, simple in preparation process, convenient to use and operate, green and environment-friendly, and has a good application prospect.
本发明提供了一种高强水凝胶石膏模具及其制备方法，涉及石膏模具技术领域。本发明通过加入少量高分子凝胶单体和聚合引发剂，同时添加少部分聚羧酸减水剂及磷酸酯类消泡剂制备出一种高强水凝胶石膏模具。即使在高水膏比下，本发明的石膏模具仍具有较高的强度。本发明显著降低了石膏原料成本，同时保证石膏模具的吸水率，提高石膏模具的使用次数。同时，本发明石膏模具的原料廉价易得，制备工艺简单，使用操作方便，绿色环保，具有良好的应用前景。
