In order to manufacturing a tire the major raw materials required are: Fabric (steel, polyester, nylon, or combination of these), Rubber (synthetic and natural types: hundred of different polymer), Reinforcing chemical (carbon black, silica, resins), Anti-degredants (ozonants, paraffin waxes), Adhesion promoters (cobalt salts, brass on wire, resins on fabric), Curatives (cure accelerators, sulphur) and processing oils (oils, trackfiers, softeners). In addition, the cure package- a combination of curatives and accelerators is used to form the tire and give it its e lasticity. Other ingredients also come into play to aid in the processing of the tire or to function as anti-oxidants, anti-ozonants and anti-aging agents.
The selection depends on the performance requirements, as they are different for the tread, sidewall and apex. Approximately one third of the compound consists of filler substances the most popular fillers are carbon black and silica.
Approximately half of the rubber is natural rubber from a rubber tree and imported from Indonesia, srilanka, Thailand etc. The rest consists of various kind of reinforcing materials. The share of rubber compounds in the total weight of a tire is more than 80%. This research paper includes brief introduction of compound formation, mixing of compound using Banbury mixer, cycle of Banbury mixer.įor the formation of the compound the main raw materials of a tire are natural rubber, synthetic rubber, carbon black and oil. The first three are primarily used as tread and sidewall compounds, while butyl rubber and halogenated butyl rubber are primarily used for the inner liner, or the inside portion that holds the compressed air inside the tire. The Mixing process was reviewed at APOLLO TYRES LTD, LIMDA (Gujarat) in which there are four major rubber used: styrene- butadiene rubber (SBR), Polybutadiene rubber (BR), and butyl rubber (along with halogenated butyl rubber). Each component has a different mix of ingredients according to the properties required for that component. Compounding is the operation of bringing together all the ingredients required to mix a batch of rubber compound. Depending on the intended use of the tire, the objective may be to optimize performance, to maximize traction in both wet and dry condition, or to achieve superior rolling resistance. The two major ingredients in a rubber compound are the rubber itself and the filler, combined in such a way as to achieve different objectives. In tire industries for making a tire mixing or compound formation of rubber is most important part. K eywor ywor ds: Mixing process, compound adding, Master rubber formation, final rubber formation, and Bale cutter. In this paper i have completely reviewed the formation of master and final rubber also discussed about the importance of compound added in the mixing of rubber. After process Rubber forwarded to the hot extruder and cold extruder for the formation of tread, bead, sidewall, ply etc. The rubber initially cut in the required proportion by Bale cutter and processed in the mixer. This formation is done in the Banbury mixer by adding various different compounds in the rubber.
