Abstract
The invention discloses a preparation method of a magnesium-aluminum hydrotalcite crystal whisker. The preparation method comprises the following steps: adding magnesium sulfate and calcium chloride to deionized water, stirring uniformly at normal temperature and normal pressure, adding aluminum chloride, sodium hydroxide and calcium carbonate, mixing uniformly, carrying out ultrasonic treatment to the mixed liquid, and then ageing, washing, filtering and drying the mixed liquid to obtain the magnesium-aluminum hydrotalcite crystal whisker. The preparation method provided by the invention is low in production cost as the raw materials for the synthetic process are easily accessible; the synthetic method is simple and easy to operate; the product is high in purity and yield.
Description
Technical field
The present invention relates to a kind of preparation method of BACN, be specifically related to a kind of preparation method of magnesium aluminum-hydrotalcite.
Background technology
Magnesium aluminum-hydrotalcite is the BACN of a kind of efficient, nontoxic, low cigarette, high performance-price ratio, whisker is the single crystal fibre with certain length-to-diameter ratio and perfect crystal formation, for submicron and nano-grade size, there is the atomic arrangement structure of high-sequential, there is the ability of reinforced composite intensity, replacing traditional magnesium aluminum-hydrotalcite can well avoid the situation causing material property to worsen because increasing loading level with whisker.
Summary of the invention
The object of the invention is to, provide a kind of preparation method of magnesium aluminum-hydrotalcite whisker, synthetic method is simple to operation, and production cost is low, and productive rate is high.
A preparation method for magnesium aluminum-hydrotalcite whisker, it comprises the following steps:
One, magnesium sulfate and calcium chloride are added in deionized water, stir under normal temperature and pressure, add aluminum chloride, sodium hydroxide and calcium carbonate, mix;
Two, mixed solution is ultrasonic;
Three, ageing, washing, filters, and dries, obtains magnesium aluminum-hydrotalcite whisker.
The preparation method of magnesium aluminum-hydrotalcite whisker provided by the invention, its beneficial effect is, building-up process is raw materials used cheap and easy to get, and production cost is low, and synthetic method is simple to operation, and product purity is high, and productive rate is high.
Embodiment
Below in conjunction with an embodiment, the preparation method of magnesium aluminum-hydrotalcite whisker provided by the invention is described in detail.
Embodiment
One, by magnesium sulfate and calcium chloride in molar ratio 3:0.1 put into the beaker being added with deionized water, stir under normal temperature and pressure, after stirring, add aluminum chloride, sodium hydroxide and calcium carbonate that mol ratio is 1:16:0.5, mix;
Two, by ultrasonic for mixed solution 20min, white flock suspension liquid is formed;
Three, then at 90 DEG C, carry out ageing 3d, with deionized water wash 2-3 time, leach precipitation, by it 100 DEG C of oven dry, obtain magnesium aluminum-hydrotalcite whisker.
