<p>The invention relates to a regenerated rubber composition, consisting of powder of used tyres, recovubber recovered from the worn out belt carriers, residues from the production of pressed gaskets, belts, plates and carpets made of rubber or pre-vulcanized mixtures, and to a process for producing the same. According to the invention, the regenerated rubber composition comprises 80...100 parts by weight of powder of used tyres, rubber recovered from used belt-carriers, residues from the production of pressed gaskets, belts, plates and carpets made of rubber, pre-vulcanized mixtures; 0.25...0.38 parts by weight of reclaiming agent containing a mixture of dixylyl disulphides and 7.5...13.5 parts by weight of regenerating plastifier consisting of black fuel oil, the said composition being subjected to the thermochemical treatment at a temperature of 200...250 C and at a pressure of 25...35 at, for 75...120 min, followed by a regeneration , as a consequance of some repeated refinings.</p> |
