Organic high-temperature binder and method for improving organic high temperature adhesive property of ceramic material
The invention relates to a method for improving an organic high temperature adhesive property of a ceramic material. Polyborosilazane (PSNB) and PBSZ are used as binders, and epoxy resin and polysiloxane (PSO) are used as oxygen molecule-containing additives. The PSNB is uniformly mixed with the epoxy resin, or the PSNB is uniformly mixed with the PSO to obtain a mixture, the mixture is applied onto the surface of ceramics is coated with the mixture, and after being vacuumized, two pieces of ceramics are in lap joint with each other. The binder adopted in the method has high adhesive strength at 1250 DEG C, 1400 DEG C and 1500 DEG C, the application requirement of the binder at high temperature is met, an ideal effect can be realized for large-area adhesion, the binder on any part is oxidized, the compactness of an adhesive layer can be improved, and the organic high temperature adhesive property of the ceramic material can be effectively improved.
