Beschreibung
Zusammenfassung:	The invention relates to a product and a process for preparing said product meant to be used as a plasticizer in rubber mixtures for technical articles. According to the invention, the product comprises 30...50% vegetable oil and 70...50% cellulose, proteins or wax, the percentage being expressed by mass. The claimed process consists in heat treating, at temperatures of 220...240°C, oil-bearing seeds selected from rape, sunflower, soya or castor-oil plant, for 25...50 min, at a pressure of 25...35 at, after which the material is homogenized for 2...5 min on a refining roll. Invenţia se referă la un produs şi la un procedeu pentru obţinerea acestuia, utilizat ca plastifiant în amestecuri de cauciuc din care rezultă articole tehnice. Produsul conform invenţiei este constituit, în procente masice, din 30...50% ulei vegetal şi 70...50% celuloză, proteine sau ceruri. Procedeul conform invenţiei constă din tratarea termică, la temperaturi de 220...240%, a unor seminţe de plante oleaginoase, alese dintre rapiţă, floarea-soarelui, soia sau ricin, timp de 25...50 min, la o presiune de 25...35 at, după care materialul este omogenizat timp de 2...5 min, pe un valţ pentru rafinare.
