Titanium boride(TiB) is difficult to disperse uniformly in the silicone resin system.How to improve the dispersion stability of TiB in the silicone resin system has become the focus of research at home and abroad.By modifying the surface of TiB particles and adding a dispersion aid,the dispersion stability in the silicone resin system was improved.The results shown that 3% of silane coupling agent KH-550 and 3% of silane coupling agent KH-570 can increase the dispersion stability of TiB in silicone resin system by more than 90%.75% of silicone resin content improved the dispersion stability of TiB particles in the silicone resin system by 85%.1% oleic acid,0.25% ethanol thickener and 2% anti-settling agent modified polyamide B-130 can make TiB dispersion stability in the system increased by more than 85%.
