Abstract
The invention discloses a preparation method for a nanometer aluminium oxide composite. The preparation method comprises the following steps: adding kaolin into deionized water, conducting ultrasonic dispersion, adding sodium biphosphate and aluminium phosphate, and conducting ultrasonic dispersion to obtain a precursor solution; then conducting heating reflux on the precursor solution under the nitrogen atmosphere; after that, conducting natural cooling and suction filtration; drying obtained solid powder at 60-90 DEG C, and grinding for 30-60 min, wherein the prepared composite is spherical, the shell of the prepared composite is made of nanometer aluminium oxide, and kaolin is coated with nanometer aluminium oxide. The composite integrates excellent performance of kaolin and nanometer aluminium oxide, and can be further used as a binding agent or reinforcing filler of other materials.
Description
Technical field
The present invention relates to the technical field of nano aluminium oxide.
Background technology
Kaolin has been widely used in the industrial production, such as can be used as binding agent, reinforcing filler, oil pad etc., in these cases, kaolinic self performance and dispersion effect often have obvious impact to the performance of material, the usual toughness of kaolin of conventional form is poor, adds after in material and easily occurs the bad phenomenon such as reunion.
Summary of the invention
The object of the invention is to the preparation method proposing a kind of nano oxidized aluminum composite, can prepare adhesive property and intensity kaolin-nano oxidized aluminum composite all preferably by this preparation method, this matrix material can be further used as binding agent or the reinforcing filler use of other materials.
Technical scheme of the present invention is as follows:
A preparation method for nano oxidized aluminum composite, comprises the following steps:
1) kaolin is added in deionized water, carry out ultrasonic disperse 10 ~ 30min, add SODIUM PHOSPHATE, MONOBASIC and aluminum phosphate in its backward dispersion liquid, again carry out ultrasonic disperse 10 ~ 30min, obtain precursor solution;
2) by precursor solution reflux 20 ~ 40min at 60 ~ 80 DEG C, in nitrogen atmosphere, thereafter naturally cooling is carried out, suction filtration is carried out after cooling, the pressed powder obtained is carried out washing with dry, at 60 ~ 90 DEG C, grind 30 ~ 60min after drying, namely obtain described nano oxidized aluminum composite.
Preferably: the mass parts of described kaolin and described SODIUM PHOSPHATE, MONOBASIC and described aluminum phosphate is respectively 5 ~ 7 parts, 0.1 ~ 0.3 part, 2 ~ 5 parts.
In addition preferably: the mass parts of described kaolin and described SODIUM PHOSPHATE, MONOBASIC and described aluminum phosphate is respectively 6 parts, 0.2 part, 4 parts.
Preparation method of the present invention is simple and easy to control, the matrix material obtained is spherical, its shell is formed primarily of nano aluminium oxide, by nano aluminium oxide, kaolin is coated on wherein, this matrix material combines the premium properties of kaolin and nano aluminium oxide, and binding agent or the reinforcing filler that can be further used as other materials use.
