The invention belongs to the technical field of rubber and plastic machinery and equipment, and particularly relates to an internal mixer rotor. Spiral angles are increased at a first long edge, a first short edge, a second long edge and a second short edge to change the circumferential flow of rubber, the length of the first long edge and the second long edge reaches half of a spiral lead, a better axial movement performance is achieved, and the distribution and dispersion of fillers and compounding agents are facilitated; with the shear heating and the decrease of the mooney drilling degreeof the rubber, the widened first long edge, first short edge, second long edge and second short edge ensure sufficient shear performance with the inner wall of an internal mixer, the stretching effectof the rubber is increased, and the full flow and dispersion of the rubber are facilitated; and the first long edge, first short edge, second long edge and second short edge in a convex block shape as well as the large spiral angles are more suitable for the silanization reaction of white carbon black in the rubber formulation, the reaction is facilitated, and the efficiency of mixing is improved.
Description
Technical field: [0001] The invention belongs to the technical field of rubber and plastic machinery equipment, and in particular relates to a rotor of an internal mixer, which is suitable for an internal mixer for reactive mixing of white carbon black. Background technique: [0002] The rubber industry has a history of more than 160 years. Rubber products are closely related to people's lives and greatly facilitate people's lives. In the rubber industry, the quality of the rubber compound determines the quality of the subsequent rubber products. The mixing process is particularly important in the rubber industry and is its core link. The mixing process is the basis and core link of the rubber product molding process. The quality of rubber products is based on the quality of the rubber compound, and the mixing equipment determines the quality of the rubber compound. is particularly important in the process. [0003] The internal mixer involved in mixing is a kind of machin...
