纳米CaCO_3改性环氧胶粘剂

Study on Modification of Epoxy Resin by Nano-CaCO_3

研究了活性纳米CaCO3对环氧胶粘剂的改性。结果表明,改性后的环氧胶粘剂性能得到很大改善,其力学性能、粘接性能、柔韧性能以及热性能均得到提高,能完全取代昂贵的白炭黑对环氧胶粘剂的补强作用,降低了成本。用异佛尔酮二胺(IPD)与酰胺基胺树脂作环氧胶粘剂的复合固化剂,可提高胶层的玻璃化温度,又可改善胶层的韧性。

The modification of epoxy resin by active nano-CaCO3 was studied. The results showed that the mechanical property, adhesive property and thermal property of the epoxy resin were improved after adding nano-CaCO3. The optimum adding amount of nano-CaCOawas 20%. It was showed that the active nano-CaCO3 could replace the expensive silica to reinforce epoxy resin and reduce the cost.
