Embodiment 1
[0052] The preparation and application of a self-curing metal anti-corrosion hybrid silica gel, comprising the following steps:
[0053] Add 90g of polydimethylsiloxane, 90g of 1,2-bis(triethoxysilyl)ethane, 140g of TEOS (tetraethyl orthosilicate) and 150g of absolute ethanol into a three-neck round bottom flask, and stir well . Add 36 g of pure water into the three-necked flask using a constant pressure funnel, then add two drops of concentrated hydrochloric acid, transfer the three-necked flask to a constant temperature water bath at 70°C, and react for 12 hours. (The constant pressure funnel is sealed for use.) Take 34.17g (KH550) from another constant pressure funnel and add it dropwise into the three-necked flask. 1.50 g of deionized water was added dropwise using a sealed constant-pressure funnel, rinsed with 40 g of absolute ethanol, and reacted at 70° C. for 12 h. Then the temperature was kept at 40°C, and methanol and part of ethanol were removed by 15kpa vacuum dis...
Embodiment 2
[0056] The preparation and application of a self-curing metal anti-corrosion hybrid silica gel, comprising the following steps:
[0057] Add 180 g of 1,2-bis(triethoxysilyl)ethane, 140 g of TEOS and 150 g of absolute ethanol into a three-neck round bottom flask, and stir evenly. Add 36 g of pure water into the three-necked flask using a constant pressure funnel, then add two drops of concentrated hydrochloric acid, transfer the three-necked flask to a constant temperature water bath at 70°C, and react for 12 hours. (The constant pressure funnel is sealed for use.) Take 34.17g (KH550) from another constant pressure funnel and add it dropwise into the three-necked flask. 1.50 g of deionized water was added dropwise using a sealed constant-pressure funnel, rinsed with 40 g of absolute ethanol, and reacted at 70° C. for 12 h. Then the temperature was kept at 40°C, and methanol and part of ethanol were removed by 15kpa vacuum distillation for 30min to obtain hybrid silica sol. Th...
Embodiment 3
[0060]The preparation and application of a self-curing metal anti-corrosion hybrid silica gel, comprising the following steps:
[0061] Add 90 g of uncapped polydimethylsiloxane, 90 g of 1,2-bis(triethoxysilyl)ethane, 140 g of TEOS and 150 g of absolute ethanol into a three-neck round bottom flask, and stir evenly. Add 36 g of pure water into the three-necked flask using a constant pressure funnel, then add two drops of concentrated hydrochloric acid, transfer the three-necked flask to a constant temperature water bath at 70°C, and react for 12 hours. (The constant pressure funnel is sealed for use.) Take another 17.08g constant pressure funnel (KH550) and add it dropwise into the three-necked flask. Add 0.75 g of deionized water dropwise using a sealed constant pressure funnel, rinse the constant pressure funnel with 40 g of absolute ethanol, and react at 70° C. for 12 h. Then the temperature was kept at 40°C, and methanol and part of ethanol were removed by 15kpa vacuum dis...
