Abstract
The invention discloses a manufacturing method of a nano porous material, which comprises the following steps: mixing and stirring ethyl orthosilicate, organic solvent and acid, performing heating reaction at 65-70 DEG C for 2-3 hours, dropwisely adding an alkali solution to regulate the pH value of the reaction solution, and further stirring to obtain a gelatinous substance; and mixing the gelatinous substance and an organic silicon resin according to a mass ratio of 1:(1-2), and stirring until the solid is uniformly dispersed, thus obtaining the nano porous material. According to the manufacturing method of a nano porous material, the porous material manufactured in such manner is stable, the average pore size is 17 nm, the porosity is up to 82%, and the porous material has favorable adsorption effect; and the raw materials used in the manufacturing method are cheap, the preparation process is simple and easy to operate, and no dangerous reaction conditions such as high temperature, high pressure and the like are required.
Description
Technical field
The present invention relates to field of porous materials, particularly relate to a kind of manufacture method of nano-porous materials.
Background technology
Porous material is a kind of material that consists of network structure mutual perforation or blind hole hole, and the border of hole or surface consist of pillar or flat board.Typical pore structure has: a kind of is to assemble in the plane by a large amount of polygonal hole the two-dirnentional structure formed, and the hexagonal structure that is similar to honeycomb due to its shape is called as " honeycomb " material; The three-dimensional structure more generally formed at space clustering by a large amount of polyhedron-shaped holes, be referred to as " foam " material usually.If the solid that forms hole only is present in the border of hole, between hole, communicate,, be called perforate.If the hole surface is also solid, each hole separates fully with hole on every side, is called closed pore, and some hole is half perforate semi-closure hole.
But unstable when porous material commonly used exists now, the preparation process complexity, the raw material of use is also very expensive, has increased production cost, can not large-arealy apply.
