| titleOfInvention | A kind of monodisperse silica nano particle and preparation method thereof |
| abstract | The invention discloses a kind of preparation method of monodisperse silica nano particle, silicon source containing organoalkoxysilane is mixed with critical, be obtained by reacting suspension liquid, described suspension liquid is carried out solid-liquid separation and obtains product, the structural formula of described organoalkoxysilane is as follows: Rn 1 m rn 2 n si (ORn 3 )n 4-m-n , in formula, m and n is integer and m+n=0,1,2 or 3; Rn 1 , Rn 2 and Rn 3 for respective independently alkyl; Described critical is that temperature is at 200 ~ 500 DEG C, the water of pressure under 5Mpa ~ 30Mpa condition; Described reaction is at 200 ~ 500 DEG C and carries out under 5 ~ 30Mpa condition.Preparation method provided by the invention, can reduce environmental pollution without the need to adding the organism such as tensio-active agent, the reaction times is short.The invention also discloses monodisperse silica nano particle prepared by a kind of aforesaid method, size distribution is comparatively even, and has middle microvoid structure, and surface-area is comparatively large, has good application prospect. |
