Method of producing an elastomeric alloy that is similar to thermoplastic elastomers, on the basis of reclaimed rubber or waste rubber |
摘要 |
An elastomer blend that is similar to thermoplastic elastomers is produced from powered reclaimed rubber or waste rubber. The powdered rubber is processed to compounds by subjecting it to a melt-mixing process in a mixer together with a thermoplastic material and at least one stabilizer. A mixture that consists of two phases that are usualy incompatible, namely the powdered rubber and a thermoplastic material, is processed to a blend that is characterized by the properties of the rmoplastic elastomers. To this end, at least one polypropylene copolymer or a mixture thereof with at least one polypropylene type is melted in the mixer and powered rubber, at least part of which has been pre-swelled in a radical donor, is dosed to the melt. The powered rubber is dispersed in the plastic matrix by applying high shearing strains and admixing radical-forming agents in order to couple the two phase.
