Description
Technical Field
The utility model relates to a sulphur preparation technical field especially relates to a device of preparation insolubility sulphur.
Background
With the rapid development of the automobile industry in China, the annual output of tires is increased year by year, and the demand of sulfur as a main vulcanizing agent of rubber is increased year by year. However, the solubility of ordinary sulfur in rubber is limited, and the solubility of the ordinary sulfur increases with the increase of temperature in the rubber mixing process, and precipitates in a crystalline form on the surface of the rubber compound when the temperature is reduced, so that the ordinary sulfur migrates to the surface of the rubber compound, namely, the phenomenon of so-called 'blooming' in the production of tires and rubber products is formed, the appearance of the products is seriously influenced, and the adhesiveness of the products is reduced.
In order to solve the problems of common sulfur blooming and the like, Insoluble Sulfur (IS) products are produced at the same time. Insoluble Sulfur (IS) IS a linear long-chain high molecular polymer for further processing sulfur (S), the number of sulfur atoms on a molecular chain IS up to more than 108, and the sulfur IS insoluble in carbon disulfide, so the insoluble sulfur IS called. The IS IS the best rubber vulcanizing agent with the recognized characteristic of no blooming, and has the following advantages: the rubber material has good self-adhesion. Can improve the bonding strength between each layer of the multi-layer rubber product, and particularly can improve the bonding performance of steel wires and rubber in the process of manufacturing tires. Insoluble sulfur is uniformly distributed in the rubber material, so that the scorching phenomenon of the rubber material during storage is effectively reduced, the storage period of the rubber material is prolonged, the uniform vulcanization is ensured, and the quality of rubber products is improved. And thirdly, because the rubber is insoluble in rubber, the rubber does not migrate to the surface of the sizing material to generate blooming, and the appearance quality of the light-colored product is ensured. In the production of automobile all-steel wire radial tires, insoluble sulfur is the best rubber vulcanizing agent and accelerator, and no substitute product exists at present.
The existing method for preparing insoluble sulfur mainly comprises a gasification method or a melting method, and the technical key points are mainly selection of a stabilizer and determination of a quenching liquid and a quenching mode. However, most manufacturers and some Chinese patents in China adopt a method of using water as quenching liquid, and some Chinese patents also adopt a method of matching carbon disulfide and a composite stabilizer in different proportions. The insoluble sulfur produced by using water as a quenching liquid has poor dispersibility, high-temperature thermal stability cannot meet the requirements of radial tires, the amount of wastewater in the production process is large, and the environmental protection problem is outstanding, Chinese patent CN 01101968.9 specially provides a production method of insoluble sulfur by a melting method without water, the insoluble sulfur produced by using carbon disulfide as the quenching liquid can basically meet the requirements of radial tires, but the boiling point is only 42.7 ℃, the flash point is-30 ℃, and the production process is extremely flammable and explosive.
