摘要
以含有机基团的硅氧烷对正硅酸乙酯溶胶进行化学改性 ,制备了有机 无机杂化成膜材料 ,并加入颜、填料 ,由正交试验优选出了杂化物涂料的配方。试验结果表明 ,杂化物涂层可在 12 0℃ ,1h固化成膜 ,35 0℃下热稳定性良好 ,耐盐雾试验达 2 0 0h ,适于严酷条件下镁合金等材料的耐热。
Inorganic/organic silicon hybrid materials were synthesized on the chemical modification of silicon sol by siloxane with an organic group. Furthermore silicon hybrid coating with better properties was prepared with selected pigments by orthogonal tests. Experimental results showed that integrative properties of the silicon hybrid coatings were excellent and it was suitable for severe corrosive environments.
