The invention discloses a vermiculite high-temperature sealant and a preparation method and a preparation device thereof. The vermiculite high-temperature sealant is prepared from 30% of chemical expanded vermiculite, 11% of talc, 5.5% of glass fiber, 0.3% of dispersing agent, 6.5% of polyester resin, 0.2% of catalyst, 1.5% of blocked isocyanate and 45% of methylbenzene. A sealant preparation all-in-one machine comprises a stirring assembly and a modifying assembly. The stirring module comprises a stirring bin, a stirring main shaft is arranged in the center of the inner bottom of the stirringbin, a plurality of feeding rods are arranged on the outer side of the circumference of the stirring main shaft, the modification module comprises an annular soaking bin, a bearing net capable of moving up and down is arranged in the annular soaking bin, and a detachable infrared lamp tube is arranged on the annular soaking bin; a liquid collecting bin is further arranged on the outer wall of themiddle of the stirring bin and communicates with the lower bottom surface of the annular soaking bin, and multiple electric control bin doors are circumferentially arranged at the positions, corresponding to the annular soaking bin, of the inner wall of the stirring bin. The vermiculite high-temperature sealant prepared by the invention can be used as compensation of a non-metal high-temperaturesealing gasket, can also be independently used as a sealing material, and has excellent sealing and temperature-resistant functions after film formation.
本发明公开了一种蛭石高温密封胶及其制备方法和制备装置，包括：30％化学膨胀蛭石、11％滑石、5.5％玻璃纤维、0.3％分散剂、6.5％聚酯树脂、0.2％催化剂、1.5％封闭异氰酸酯、45％甲苯；密封胶制备一体机包括搅拌组件、改性组件；搅拌模块包括搅拌仓，其内底部中心处设有搅拌主轴，搅拌主轴的圆周外侧设有多个加料棒，改性模块包括环形浸泡仓，其内设有可上下活动的承载网，其上设有可拆卸的红外光灯管；搅拌仓中部外壁还设有集液仓与环形浸泡仓下底面连通，搅拌仓内壁与环形浸泡仓位置对应处周向设有多个电控仓门。本发明制备的蛭石高温密封胶能够作为非金属高温密封垫片的补偿，还可以单独作为密封材料使用，成膜后密封和耐温功能优异。
