Description

Technical Field

[0001] The utility model relates to the technical field of rubber production equipment, in particular to a normal pressure continuous sulfur cutting and quantitative compounding device. Background Art

[0002] The instant fluid black gold particles are made of tire tread materials as the main raw materials. After high-temperature shear decrosslinking, the rubber SS or SC bonds are completely broken to form small molecules. The product is fluid at high temperatures and paste at room temperature. The fluid rubber after high-temperature decrosslinking is mixed and modified with other polymer materials and then granulated. It is mainly used in tires, conveyor belts, shoe materials, waterproof materials, and asphalt pavement rubber modified materials. After application, it can effectively reduce the use of oil, carbon black, natural rubber, and styrene-butadiene rubber.

[0003] In the production process of instant fluid black gold particles, the rubber material is only subjected to preliminary magnetic separation in the early stage of desulfurization, and impurities such as steel wire and aluminum sheets cannot be removed. When granulating after desulfurization and compounding, the granulated particles are easily loose and uneven in size due to pressure fluctuations, affecting product quality. In addition, the addition of modified materials after desulfurization is single and cannot meet the product needs of different customers. Utility Model Content
