Reclamation of waste fiber produced by rubber reclamation

Two techniques were used to reclaim the waste fiber produced by tire reclamation process which contained with some waste rubber powder, one was making short fiber rubber masterbatch, another one was making resin pellet. The results showed that by adding direct adhesive to short fiber rubber masterbatch, the tensile strength of masterbatch vulcanizate in excess of 20 MPa and the tear strength in excess of 50 kN/m were reached. This masterbatch could be molded to produce some rubber products, and its properties were more acceptable when it was blended with other rubber compound. The properties of reclaimed nylon pellet changed with the amount of waste rubber it contained, and decreased with the increase of the amount of waste rubber. Through a patent way separating waste rubber from waste fiber, the properties of reclaimed nylon pellet approached to that of nylon 6 pellet(1013B) produced by UBE Co. The reclaimed nylon pellet could be injected into plastic production. The above two reclamation techniques possessed notable economic profit.
