Preparation method of high-strength plastering gypsum
The invention relates to a preparation method of high-strength plastering gypsum, and belongs to the technical field of building materials. The gypsum whiskers and the carbon nanotubes are added to prepare the high-strength plastering gypsum, the gypsum whiskers are highly ordered in atomic structure arrangement during crystallization, the strength of the whiskers is close to the theoretical strength of atomic valence bonds of a material, the strength of the plastering gypsum can be effectively reinforced, and the gypsum whiskers are fibrous crystals capable of absorbing impact energy; and themechanical strength is high. The plastering gypsum has the advantages that crack propagation can be effectively inhibited in the plastering gypsum cracking process, and the strength of the plasteringgypsum can be remarkably improved through the carbon nanotubes; meanwhile, the toughness and impact fatigue resistance of the plastering gypsum are well improved, the mechanical property of the plastering gypsum can be effectively improved through doping of the carbon nanotubes, and the tensile strength and the breaking strength of the plastering gypsum are improved to different extents.
本发明涉及一种高强度粉刷石膏的制备方法，属于建筑材料技术领域。本发明通过添加石膏晶须和碳纳米管，制备一种高强度粉刷石膏，石膏晶须在结晶时原子结构排列高度有序，使晶须的强度接近材料原子间价键的理论强度，可以有效补强粉刷石膏的强度，由于石膏晶须的是纤维状晶体能吸收冲击能量，而且其机械强度大，在粉刷石膏破裂过程中能有效抑制裂纹扩展，碳纳米管能够使粉刷石膏的强度得到显著的提高，同时对于粉刷石膏的韧性和抗冲击疲劳性能都有很好的改善，在碳纳米管的掺入能有效的改善粉刷石膏的力学性能，使粉刷石膏的抗拉强度和抗折强度都得到不同程度的提高。
