Gypsum material for jewelry mold and preparation method thereof
The invention relates to the technical field of gypsum material preparation methods, and provides a gypsum material for a jewelry mold and a preparation method thereof.The preparation method comprises the steps that methyl alkenyl polyoxyethylene polyoxypropylene block ether, sodium methallyl sulfonate, acrylic acid and methyl acrylate are added into the gypsum material to be polymerized to generate polycarboxylic acid macromolecule modified components; the breaking strength of the gypsum material can be improved to a certain extent; secondly, the modified polypropylene glycol fiber, the modified basalt fiber and the modified lignocellulose are modified and then added into the gypsum material according to different mixing amounts, so that the compressive strength and the water resistance of the gypsum material can be improved; the first component and the second component are added, so that the gypsum material has more stable antibacterial performance, the flame-retardant and fireproof performance of the gypsum material can be improved, the probability of smoldering and mildewing of the gypsum material due to addition of fibers and organic components is reduced, and the market application value of the gypsum material is improved.
本发明涉及石膏材料制备方法技术领域,提供一种用于首饰模具的石膏材料及其制备方法,本发明在石膏材料中加入以甲基烯基聚氧乙烯聚氧丙烯嵌段醚、甲基丙烯磺酸钠、丙烯酸和丙烯酸甲酯为单体聚合生成的聚羧酸大分子改性组分,能够在一定程度上提高石膏材料的抗折强度;其次,将改性聚丙烯醇纤维、改性玄武岩纤维和改性木质纤维素经改性后按照不同的掺量加入到石膏材料中,能够提高石膏材料的抗压强度和耐水性;而且通过第一组分和第二组分地加入,既能够使石膏材料具有更加稳定的抗菌性能,又能提高石膏材料的阻燃防火性能,降低石膏材料因添加纤维和有机组分而发生阴燃和生霉变的几率,从而提高石膏材料的市场应用价值。
