摘　　要：研究了壁流式蜂窝陶瓷堵孔材料的制备工艺,探讨了加热体积膨胀剂的加入量、烧成温度以及各烧成温度下堵孔材料的膨胀与收缩情况对壁流式蜂窝陶瓷堵孔材料膨胀性能的影响。研究结果表明,当配方中加入25 wt%的加热体积膨胀剂,在1160℃下烧成,可以制备出与壁流式蜂窝陶瓷载体结合牢固,抗折强度为3.72 MPa且干燥收缩率和烧成收缩率符合壁流式蜂窝陶瓷性能要求的堵孔材料。This paper aims at studying the preparation technology of wall-flow ceramic blocking materials and exploring addition of heating volume expanding agent and firing temperature as well as impacts of blocking materials expansion and contraction on expansive property of wall-flow ceramic blocking materials under the firing temperature. The study shows that the blocking materials, with the bending strength of 3.72 MPa, which strongly combines wallflow ceramic carrier and whose drying shrinkage and firing shrinkage meet the performance requirement of wallflow ceramic, can be prepared on the condition of adding 25 wt% heating volume expanding agent in the experimental formula and firing of 1160 ℃.
