High-strength light-weight spray coating and preparation method thereof
The preparation method specifically comprises the following steps: carrying out dry mixing on light mullite particles and shale ceramsite, so as to obtain light aggregate particles; uniformly mixing kaolin, pure calcium aluminate cement, rho-Al2O3 powder and silicon dioxide micro powder, and adding the mixture into the lightweight aggregate particles to obtain an intermediate material; adding organic fibers into the intermediate material for ball milling, and adding water for mixing after ball milling; after mixing is completed, the high-strength light-weight spray coating is prepared. The high-strength light-weight spray coating is prepared from the following components in parts by weight: 35 to 45 parts of light-weight mullite particles, 20 to 25 parts of shale ceramsite, 10 to 20 parts of kaolin, 15 to 20 parts of pure calcium aluminate cement, 5 to 10 parts of rho-Al2O3 powder, 5 to 7 parts of silicon dioxide micro powder, 1 to 3 parts of additional organic fiber and 5 to 10 parts of additional water. The lightweight mullite particles and the shale ceramsite are used as different lightweight aggregates, so that the low volume density performance of the spray coating is ensured.
本发明公开了一种高强轻质喷涂料及其制备方法，具体包括如下步骤：将轻质莫来石颗粒与页岩陶粒进行干混，得到轻质骨料颗粒；取高岭土、纯铝酸钙水泥、ρ‑Al2O3粉、二氧化硅微粉混合均匀后，加入至轻质骨料颗粒中，得到中间料；取有机纤维加入至中间料中进行球磨，球磨后加入水混炼；混炼完成后制得所述高强轻质喷涂料；所述高强轻质喷涂料的各成分用量如下：轻质莫来石颗粒35~45份、页岩陶粒20~25份、高岭土10~20份、纯铝酸钙水泥15~20份、ρ‑Al2O3粉5~10份、二氧化硅微粉5~7份、外加有机纤维1~3份，外加水5~10份。本发明中采用轻质莫来石颗粒和页岩陶粒作为不同的轻质骨料，确保了喷涂料低体积密度的性能。
