Composition for gypsum board, gypsum plaster board and preparation method of gypsum plaster board
The invention relates to a composition for a gypsum board, a gypsum plaster board and a preparation method of the gypsum plaster board, and belongs to the technical field of building materials. The composition for the gypsum board comprises the desulfurized gypsum, the hollow glass beads, the redispersible latex powder, the fiber material and the modified starch, the hollow glass beads have the characteristics of light weight, hollowness and high strength, and have a closed sphere structure, thin gas is contained in the hollow glass beads, and the hollow glass beads can be recycled. The material has the advantages of small heat conductivity coefficient, high strength, low density, low water absorption and high temperature resistance. The gypsum board prepared from the composition for the gypsum board has the advantages of being low in density, good in heat preservation effect, good in stability, resistant to high temperature, fireproof, capable of insulating sound and reducing noise and long in service life. Besides, the gypsum board prepared from the composition for the gypsum board has high strength and high toughness, and does not deform, crack and mildew when being used in a humid environment.
本发明涉及一种石膏板用组合物、纸面石膏板及其制备方法，属于建筑材料技术领域。本发明的石膏板用组合物包括脱硫石膏、中空玻璃微珠、可再分散乳胶粉、纤维材料和改性淀粉，其中的中空玻璃微珠具有轻质、中空、高强度的特点，并且具有封闭球体结构，其内部含有稀薄气体，具有导热系数小、强度高、密度低、吸水率低和耐高温的优点。本发明的石膏板用组合物制备的石膏板具有密度低、保暖效果好、稳定性好、耐高温、防火、隔音降噪和使用寿命长的优点。另外，本发明的石膏板用组合物制备的石膏板具有高强、高韧的性能，在潮湿环境中使用时，不会发生变形、开裂、发霉情况。
