Ceramic material organic high-temperature binder and method for improving performance of binder
The invention provides a ceramic material organic high-temperature adhesive and a method for improving the performance of the adhesive, and belongs to the technical field of ceramic adhesives. In order to solve the problem of low bonding strength caused by low ceramic rate and low densification of a bonding layer of an existing bonding agent, a SiHfBCN ceramic precursor is taken as a matrix, TiB2 is taken as a filler, and the matrix and the filler are uniformly mixed according to a mass ratio of 8: (0.7-9) to obtain the bonding agent, then the SiC ceramic matrix to be bonded and the bonding agent are respectively pretreated, and the bonding agent is prepared. The bonding surfaces of the SiC ceramic matrix to be bonded are coated with the bonding agent, every two opposite bonding surfaces are in lap joint with each other, curing treatment is conducted after pressurization, and then heat treatment is conducted in a box-type furnace. The ceramic material organic high-temperature binder can effectively improve the ceramic yield and improve the compactness of a bonding layer, the room-temperature bonding strength in air after heat treatment is improved by about 262% at most, and the high-temperature toughness of the binder is effectively improved.
本发明提出一种陶瓷材料有机高温粘结剂及提高粘结剂性能的方法，属于陶瓷粘粘剂技术领域。针对目前的粘结剂低陶瓷率和粘结层低致密化所致的粘结强度低的问题，本发明通过以SiHfBCN陶瓷前驱体为基体、以TiB2为填料，并将两者按照质量比8：0.7~9的比例混合均匀，得到粘结剂，再分别对待粘结SiC陶瓷基体和粘结剂做预处理后，将粘结剂涂覆在待粘结SiC陶瓷基体的粘接表面，并将两两相对的粘接表面相互搭接，加压后固化处理，再于箱式炉内进行热处理。本发明的陶瓷材料有机高温粘结剂能够有效提高陶瓷产率，改善粘结层的致密性，热处理后在空气中室温粘结强度最高提升约262%，且粘结剂的高温韧性得到有效提升。
