Abstract

The invention discloses a preparation method of nano sulfur slurry. The preparation method comprises the following steps of: (1) respectively weighing sulfur powder with the grain diameter of 20-100Mum and water according to the mass ratio of 1: (1.225 to 8.6), pouring the sulfur powder and the water into a vessel, and dispersing for 20-30 minutes by using an emulsifying machine with the rotation speed of 10000-28000rpm; (2) pouring the slurry prepared in the step (1) into a ball milling can, adding a ball milling medium, a dispersing agent and a heat stabilizer with the addition amount of respectively 5-8 times, 2 to 6 percent and 2-5 percent of the sulfur powder by mass, and well sealing the ball milling can; (3) putting the ball milling can into a ball mill with the rotation speed of 300 to 500rpm, dispersedly milling with the ball milling time of 5 to 10h; and (4) removing granular impurities which can not disperse after the ball milling from the sulfur slurry through a vacuum suction filter with the filtering mesh number of 600 meshes, recovering the impurities and preparing the nano sulfur slurry with the grain size of 10nm to 80nm. The prepared sulfur grains are easy to disperse and have good stability and wide application prospect.

Description

technical field

[0001] The invention relates to a preparation method of nano-sulfur slurry. Background technique

[0002] Inorganic sulfur exists widely and abundantly in nature in pure state or compound form. Sulfur is one of the most important nutrients for plants. As a natural product of nature, sulfur has excellent properties, such as the treatment of impotence, deficiency-cold diarrhea and cold stool; external use to treat scabies, eczema and scabies; it also has the functions of sterilization, anti-mildew and deworming, and has been widely used in various fields. It has been valued by people since ancient times, and the smaller the particle size of sulfur, the more prominent various functions are, but the sulfur is easy to agglomerate, the density is also relatively large, and it is less soluble in various solvents (except carbon disulfide). Therefore, it is difficult to achieve small particles of sulfur in practice, and it is evenly and stably suspended in water, w...
