Abstract

The invention relates to an internal mixer rotor for mixing short fiber rubber composite materials, which is used for mixing the short fiber rubber composite materials and realizing uniform dispersing and distributing of short fibers in a rubber matrix. The internal mixer rotor comprises a front rotor and a rear rotor, which are used in a paired manner. The front rotor adopts the structure that a small clearance long rotor edge, a middle clearance short rotor edge and a big clearance long rotor edge are distributed on the left side of a rotor block and are in left-handed rotation; a small clearance short rotor edge, a middle clearance long rotor edge and a big clearance short rotor edge are distributed on the right side of the rotor block and are in right-handed rotation; the rear rotor adopts the structure that a small clearance long rotor edge, a middle clearance short rotor edge and a big clearance long rotor edge are distributed on the right side of a rotor block and are in left-handed rotation; a small clearance short rotor edge, a middle clearance long rotor edge and a big clearance short rotor edge are distributed on the left side of the rotor block and are in right-handed rotation. The internal mixer rotor is suitable for mixing various rubber materials of different formulas containing short fibers, the uniform dispersing and distributing of the short fibers in the rubber matrix are realized, the mixing process is optimized, and the quality of a rubber compound is improved.

Description

technical field [0001] The invention belongs to the technical field of rubber product processing, and relates to an internal mixer rotor used for mixing short-fiber rubber composite materials, in particular to a rotor configuration suitable for mixing short-fiber rubber composite materials and adopting the configuration. The rotor of the internal mixer realizes the mixing of short-fiber rubber composite materials and realizes the uniform dispersion and distribution of short fibers in the rubber matrix. Background technique [0002] Short fiber rubber composite material is a new type of polymer material, which combines the rigidity of short fibers and the flexibility of rubber, which can endow rubber products with high modulus, high hardness, tear resistance, load fatigue resistance, low bio It has a series of excellent properties such as heat and low compression set, so it is one of the ideal materials for tire tread rubber. In the preparation process of short-fiber rubber ...
