Embodiment

[0012] The whole of this embodiment includes a front rotor A and a rear rotor B, with a speed ratio of 1:1, rotating in opposite directions, which is performed on an X(S)M-1.7 internal mixer experimental platform. Front rotor A, the rotor prisms 2, 3, 4, 5, 6, 7 are welded to the rotor body 1. According to the gap between the top of the ridge and the inner wall of the mixing chamber, it is divided into small gap rotor long rib 2, small gap rotor short Edge 7, medium gap rotor long edge 6, medium gap rotor short edge 3, large gap rotor long edge 4, large gap rotor short edge 5; small gap rotor long edge 2, medium gap rotor short edge 3, large gap rotor long edge 4 Distributed on the left side of the rotor body 1, left-handed, the starting point of the spiral is uniformly distributed at 120° in the circumferential direction, and the spiral angle is 34 to 35°. The short edge of the rotor with small gaps is 7, the long edge of the rotor with medium gaps is 6, and the gap is large. ...

Abstract

The invention relates to an internal mixer rotor for mixing short fiber rubber composite materials, which is used for mixing short fiber rubber composite materials and realizing uniform dispersion and distribution of short fibers in a rubber matrix. The rotor is divided into a front rotor and a rear rotor, which are used in pairs. For the front rotor, the long edge of the small clearance rotor, the short edge of the medium clearance rotor, and the long edge of the large clearance rotor are distributed on the left side of the rotor body. Right side, right-handed; rear rotor, small clearance rotor long edge, medium clearance rotor short edge, large clearance rotor long edge distributed on the right side of the rotor body, left-handed, small clearance rotor short edge, medium clearance rotor long edge, large clearance rotor The short edges are distributed on the left side of the rotor body, right-handed. It is suitable for the mixing of various short fiber-containing rubber materials with different formulations, realizes the uniform dispersion and distribution of short fibers in the rubber matrix, optimizes the mixing process, and improves the quality of the mixed rubber.

Description

Technical field [0001] The invention belongs to the technical field of rubber product processing, and relates to an internal mixer rotor for mixing short-fiber rubber composite materials, specifically a rotor configuration suitable for mixing short-fiber rubber composite materials and adopting the configuration The type of internal mixer rotor realizes the mixing of short fiber rubber composite materials and 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. It combines the rigidity of short fiber and the flexibility of rubber. It can endow rubber products with high modulus, high hardness, tear resistance, load fatigue resistance, and low production. With a series of excellent properties such as heat and low compression set, it is one of the ideal materials for tire tread rubber. In the preparation process of short-fiber rubber composites, mixing is t...
