Solid rocket engine shell core mold gypsum formula and preparation method
The invention discloses a solid rocket engine shell core mold gypsum formula and a preparation method. The solid rocket engine shell core mold gypsum formula comprises the following raw materials in parts by weight: 40-80 parts of water fiber white gypsum powder, 20-50 parts of masonry cement, 1-10 parts of high-performance hollow glass beads and 30-100 parts of water. The preparation method comprises the following steps: uniformly mixing water fiber white gypsum powder, masonry cement and high-performance hollow glass beads according to a mass ratio by using a stirrer, weighing the powder and water, manually stirring uniformly, manually coating the powder and water on the surface of a shell core mold to prepare a gypsum core mold, airing at room temperature, drying at low temperature, covering cracks on the surface of gypsum with metal aluminum foil to reinforce, and curing to obtain a finished product. And finally pasting a high-temperature adhesive tape on the surface of the gypsum to serve as a core mold finished product. The gypsum for the solid rocket engine shell core mold can be simply and conveniently prepared from the raw materials of the water fiber white gypsum powder, the masonry cement, the high-performance hollow glass beads and the water in different proportions, the strength of the dried gypsum is high, the gypsum is easily knocked out subsequently, and the problem of gypsum cracking is solved.
本发明公开了一种固体火箭发动机壳体芯模石膏配方及制备方法,按重量份包括如下原料：水纤维白石膏粉40~80份、砌筑水泥20~50份、高性能空心玻璃微珠1~10份，水30~100份。使用搅拌器将水纤维白石膏粉、砌筑水泥、高性能空心玻璃微珠按质量比例混合均匀，称取粉体和水，人工搅拌均匀后，手工刮涂到壳体芯模表面制成石膏芯模，先室温晾置，再低温烘干，石膏表面的裂纹使用金属铝箔覆盖加强，最后在石膏表面粘贴高温胶带后作为芯模成品使用。本发明采用水纤维白石膏粉、砌筑水泥、高性能空心玻璃微珠和水不同配比的原料，能够简便的制备出固体火箭发动机壳体芯模用石膏，石膏干燥后强度高、后续易于敲除且改善了石膏开裂问题。
