Embodiment 1
[0044] A modified silane coupling agent is prepared as follows:
[0045] 3-Chloropropyltriethoxysilane and triethylamine (the molar ratio of 3-chloropropyltriethoxysilane and triethylamine is 1:1) were added to a chamber equipped with a reflux device, a thermometer and a dropping funnel. In the four-necked flask, start the strong stirrer, dropwise add isopropyl 3-aminocrotonate (the molar ratio to 3-chloropropyltriethoxysilane is 1:1) into the flask within 30min, and gradually heat up to 80 ℃, reflux reaction for 5h; suction filtration to remove amine salt precipitation, the filtrate is purified by vacuum distillation, that is, modified silane coupling agent; the whole reaction process is nitrogen protected and strictly waterproof. The structural formula of the modified silane coupling agent is:
[0046] .
[0047] Structure Characterization: 1 H NMR (400 MHz, DMSO-d6): 4.56 (m, 1H, C H -( CH 3 ) 2 ), 4.11 (s, 1H, C=C H ), 3.89 (m, 6H, Si-O-C H 2 ), 2.92 (t, 2H, N-C...
Embodiment 2
[0052] The preparation of a modified silane coupling agent is the same as in Example 1.
