Problems solved by technology

[0004] As an excellent rubber reinforcing filler, carbon black is widely used in the rubber industry. It is the second most used component in addition to the rubber itself. In the process of rubber compound processing, the mixing process is very important, which will The role of fillers and other ingredients in eating and dispersing in polymers. The traditional process is realized by batch mixing or continuous mixing of fillers and solid rubber or particles, that is, dry mixing. Due to the large carbon black particles The surface area and negative distance are very easy to agglomerate, so it is difficult to evenly disperse in the polymer body. In addition, the traditional dry method has the disadvantages of high energy consumption, high pollution, and poor working environment.
[0005] The invention mainly solves the problem that plant fibers are not uniformly dispersed in rubber products, and are prone to agglomeration and affect the performance of finished rubber products.

Abstract

The invention discloses an anti-cracking and anti-aging connecting plate rubber material for a transmission shaft of an automobile. The connecting plate rubber material is prepared by adding modifiedreed fiber particles into a basic rubber material body. The rubber material has the advantages that the modified reed fiber particles are added, the prepared porous mesh reed fiber particles mostly contain lignin constitution structures, lignin contains more active groups such as aromatic groups, alcohol hydroxyl groups, carboxyl groups, methoxyl groups, conjugated double bonds and the like, various types of reactions can be easily generated between lignin and rubber as well as an inorganic filler, and the lignin can be subjected to reactions such as grafting and crosslinking with the rubber,so that the lignin achieves the effect of reinforcing the rubber; and the combined effect of modified carbon black and reed fibers is adopted, so that the polarity of the reed fibers is greatly reduced, the dispersing effect of the reed fibers in the rubber is better, and the agglomeration phenomenon is relatively few.

Description

technical field [0001] The invention relates to the technical field of special processing and manufacturing of new automobile materials, in particular to an anti-crack and anti-aging rubber material for an automobile transmission shaft connecting disc. Background technique [0002] The transmission process is not stable, and it is necessary to reduce the damage to the transmission shaft due to stress concentration. The name of the supporting rubber in the middle of the transmission shaft is an elastic rubber cushion. If the elastic rubber cushion is torn or deformed, it must be replaced. Excellent connection plate can reduce vibration, slow down resonance and protect drive shaft. [0003] Mixing is to mix the plasticized raw rubber and compounding agent through the mechanical stirring effect of the rubber mixer, so that the compounding agent is completely and evenly dispersed in the raw rubber. Mixing is one of the important processes in the production of rubber products. I...
