preparation example Construction
[0023] The preparation method of the silane-modified clay can be prepared by a conventional method in the art, for example, the preparation steps are: take 10 g of montmorillonite clay and 10 mL of silane, add it to 80 mL of ethanol, stir at 60 ° C for 4 h at a speed of 300 r / min Place, remove the supernatant and wash repeatedly several times, transfer to a constant temperature drying oven at 80°C for drying, dry and grind, and activate at 105°C for 2 hours for later use.
[0024] Preferably, the silane is selected from one or more of acyloxysilanes, alkylsilanes, mercaptosilanes, and aminosilanes.
[0025] More preferably, the acyloxysilane is methacryloxysilane.
[0026] More preferably, the volume ratio of the acyloxysilane to the alkylsilane is 1:(2-3).
[0027] More preferably, the alkylsilane is C8-C16 alkylsilane.
[0028] Preferably, the C8-C16 alkylsilane is selected from one of octyltriethoxysilane, octyltrimethoxysilane, dodecyltriethoxysilane and dodecyltrimethox...
