Summary: | The invention discloses an insoluble sulfur production method and belongs to the technical field of production of rubber accelerators. The insoluble sulfur production method comprises the following steps: a, heating molten sulfur; b, atomizing at a supersonic speed, and performing nitrogen crushing; c, cooling sulfur powder, and collecting insoluble sulfur by using a bag type capturer; d, extracting at a normal temperature and normal pressure with a solvent, and adding a composite stabilizer. The insoluble sulfur production method has the advantages that 1, the sulfur powder consists of spherical granules, the particle size of the sulfur powder can be at a micron grade, and high dispersibility and high fineness requirements of application to rubber tires can be met; 2, a good carbon disulfide extraction effect of the product is achieved, and the insoluble sulfur content of the sulfur powder can be increased by 3-5% when being compared with that of 60 powder produced by using a conventional method; 3, the proc |
