Zusammenfassung: | The invention relates to a plasticizer for rubber and to rubber compositions containing the same. According to the invention, the plasticizer obtained from recycled material and renewable sources comprises one or several of the following components: glycerine, fatty acids, spent oil and/or fuel oil as a distillation residue of crude oil, and has a density of 0.900...1.050 g/cm, a kinematic viscosity of 45...75 mmsat 50°C and a flammability point of more than 90°C, being meant to be used in rubber compositions and regenerated rubber compositions, in an amount of 5...60 parts by weight from the polymer weight.
Invenţia se referă la un plastifiant pentru cauciuc şi la compoziţii de cauciuc ce conţin acest plastifiant. Plastifiantul conform invenţiei, obţinut din materiale recuperate şi surse regenerabile, are în compoziţie una sau mai multe dintre următoarele componente: glicerină, acizi graşi, ulei uzat şi/sau păcură ca reziduu de distilare a ţiţeiului, şi are o densitate de 0,900...1,050 g/cm, o viscozitate cinematică, la 50°C, de 45...75 mms, şi un punct de inflamabilitate mai mare de 90°C, şi se utilizează în compoziţii de cauciuc şi cauciuc regenerat în cantitate de 5...60 părţi în greutate din greutatea polimerului. |
