Organic-inorganic functionalized hybrid silica sol as well as preparation method and application thereof
The invention discloses an organic-inorganic functionalized hybrid silica sol and a preparation method and application thereof, the organic-inorganic functionalized hybrid silica sol contains a compound shown as a formula I: # imgabs0 # m and n are integers, R and R1 are alkyl and can be the same, R2 is octyl, octadecyl, 6-phenyl hexyl, 12-phenyl dodecyl, perfluorohexadecyl, pentafluorophenyl, tridecafluorooctyl, 3-aminopropyl, gamma-(2, 2, 6, 6, 6-tetrafluorooctyl)-2, 2, 6, 6-tetrafluorooctyl)-2, 2, 6, 6-tetrafluorooctyl, 1, 2, 6-tetrafluorooctyl, 1, 2, 6-tetrafluorooctyl, 1, 2, 6-tetrafluorooctyl, 1, the polymer is one of 2, 3-epoxypropoxy propyl and gamma-methacryloyloxy propyl. The invention further discloses a preparation method of the polymer. The organic component is introduced through joint hydrolytic polycondensation of the siloxane monomer containing the functionalized functional group and orthosilicate, and introduction of the functionalized functional group is realized on the premise of ensuring the inorganic component. A series of silica sol with strong hydrophobicity, good film-forming property, high reinforcing strength and the like is synthesized according to actual needs. The series of silica sol has the advantages of high hardness, high wear resistance, high weather resistance, heat resistance and the like of an inorganic coating, and also has the advantages of toughness, corrosion resistance, hydrophobicity, alkali resistance and the like of an organic reinforcing agent.
本发明公开了有机‑无机功能化杂化硅溶胶及其制备方法和应用，含有式I化合物：#imgabs0#m、n均为整数，其中R、R1均为烷基且可相同，R2为辛基、十八烷基、6‑苯基己基、12‑苯基十二烷基、全氟十六烷基、五氟苯基、十三氟辛基、3‑氨基丙基、γ―(2,3‑环氧丙氧)丙基、γ‑甲基丙烯酰氧基丙基中的一种。通过含功能化官能团的硅氧烷单体与正硅酸酯类共同水解缩聚来引入有机组分，在保证无机成分的前提下实现功能化官能团的引入。根据实际需要合成具有疏水强、成膜性好、加固强度高等系列硅溶胶。该系列硅溶胶共性为同时具有无机涂层的高硬度、高耐磨、高耐候性、耐热性等优异性能，而且具有有机加固剂的韧性、耐蚀性、疏水性、耐碱性等优点。
