Example Embodiment
[0037] Example 1
[0038] The preparation of silica / polystyrene microspheres includes the following raw materials:
[0039] Styrene 8 parts
[0040] γ-methacryloxypropyl trimethoxysilane 0.6 part
[0041] Ethyl orthosilicate 5 parts
[0042] 0.6 parts of divinylbenzene
[0043] Hexadecane 0.8 parts
[0044] Azobisisobutyronitrile 0.15 parts
[0045] Methacrylic acid 1.6
[0046] Acrylonitrile 1 part
[0047] Sodium dodecyl diphenyl ether disulfonate 0.01 part
[0048] 95 parts of water
[0049] Ammonia water 1.5 parts (mass fraction 28%)
[0050] The specific preparation method is as follows:
[0051] Weigh styrene, hexadecane, γ-methacryloxypropyltrimethoxysilane, ethyl orthosilicate, divinylbenzene, methacrylic acid, and azobisisobutyronitrile as the oil phase. Dissolve sodium dodecyl sulfonate in water as the water phase. After the oil phase is stirred and mixed, slowly add it to the water phase, pre-emulsify it with magnetic stirring at room temperature for 30 minutes, and then use high-spe...
