Abstract
The invention presented here deals with getting one of the raw materials of a new refractory binder system, the modified coal-tar pitch starting with heating the coal-tar, according to the specific distillation curve, later reaching a final distillation temperature of around 470° C., resulting in getting a final compound with a concentration of benzo(a)pyrene in the order of 600 ppm, together with the mixture of other raw materials for the composition of the binder system, such as anthracene oil (AO), soybean oil, linseed oil, castor oil, diesel oil, rapeseed oil, biodiesel, biopitch (Vegetable tar), paraffin, dextrin (corn starch), stearine, paraffin, vegetable waxes (cupuassu seed, shea nut, murumuru palm waxes), phenolic resins, furane resins, urethanes, epoxy, vinyl chloride, polyethylene and ethyl polyterephthalate.
