Embodiment 1

[0019] Make mercuric nitrate solution into 0.01mol / L acidic dilute solution (pH<6.0), add thioacetamide solution (concentration is 5 times of mercuric nitrate) under magnetic stirring, and stir at 1000 rad / min or more for 1 second Afterwards, the temperature was raised to boiling at a rate of 5°C / min, and the reflux reaction was continued for 50 minutes to obtain a red powder. After cooling, the red powder was centrifuged and washed five times with ethanol and deionized water (ultrasonic dispersion was required for each wash), and dried in an oven to obtain dry Mongolian silver bead nanopowder.

Embodiment 2

[0021] Make mercuric nitrate into a 0.05mol / L acidic dilute solution (pH<6.0), add thioacetamide solution (concentration is 8 times that of mercuric nitrate) under magnetic stirring, rotate at 1000rad / min or more, and stir for 5 seconds Afterwards, the temperature was raised to boiling at a rate of 10°C / min, and the reflux reaction was continued for 30 minutes to obtain a red powder. After cooling, the red powder was centrifuged and washed four times with ethanol and deionized water (ultrasonic dispersion was required for each washing), and dried in an oven to obtain dry Mongolian silver bead nanopowder.

Embodiment 3

[0023] Make mercuric nitrate solution into 0.1mol / L acidic dilute solution (pH<6.0), add thioacetamide solution (concentration is 10 times of mercuric nitrate) under magnetic stirring, and stir for 10 seconds at rotation speed above 1000rad / min Afterwards, the temperature was raised to boiling at a rate of 15°C / min, and the reflux reaction was continued for 10 minutes to obtain a red powder. After cooling, the red powder was centrifuged, washed three times with ethanol and deionized water (ultrasonic dispersion was required for each wash), and dried in an oven to obtain dry Mongolian silver bead nanopowder.

Abstract

The invention discloses a preparation method for mongolian medicine vermilion nanometer powder. The method is as follows: mercury nitrate and thioacetamide are used as raw materials for preparation of nanometer mercuric sulfide by using a wet process; a solution with a certain concentration is prepared from the raw materials; the raw materials are rapidly mixed under magnetic stirring, and the solution is uniformly heated until the solution boils so as to prepare nanometer mercuric sulfide powder. According to the invention, environmental pollution in traditional preparation processes for mongolian medicine vermilion is reduced, the process of preparation is more controllable, components are more specific, and quality of different batches of the nanometer powder is stable.

Description

technical field [0001] The invention relates to the field of preparation of Mongolian medicine silver bead powder, in particular to a preparation process of silver bead nanopowder. Background technique [0002] Silver beads, that is, silver vermilion, are refined from sulfur and mercury. It is dry and strong, and it can also rot gums and tendons. Its merits and demerits are the same as light powder. Also known as spiritual sand, it lifts and lowers yin and yang, and it helps water and fire, and it is a magic pill for helping danger and emergency, but it should not be taken for a long time. Su Dongpo said that this medicine can cure chronic nausea, all kinds of vomiting, and convulsions in children, because it has the wonderful effect of cooperating with yin and yang. Xizhu is a precious red inorganic pigment with strong covering power. It is famous all over the world for its bright color, long-lasting color and insect-proof and anti-moth. Zhu made. Silver beads are used i...
