摘要

硼化钛在有机硅树脂体系中很难均匀分散,如何提高硼化钛在有机硅树脂体系中的分散稳定性成为国内外研究的焦点。通过对硼化钛粒子表面进行改性并添加分散助剂来提高其在有机硅树脂体系中的分散稳定性。结果表明:3%的硅烷偶联剂KH-550和3%的硅烷偶联剂KH-570均可使硼化钛在有机硅树脂体系中的分散稳定性提高90%以上;75%的有机硅树脂含量使硼化钛粒子在有机硅树脂体系中的分散稳定性提高85%;1%的油酸、0.25%的乙醇增稠剂和2%的防沉剂改性聚酰胺B-130均可使硼化钛在有机硅树脂体系中的分散稳定性提高85%以上。

Abstract

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%.
