| Descripció: | Polymerized thermostable resins were obtained from legnine, extracted from sugar cane bagasse. This was done in two stages: The lignine is phenolized by reaction in an acid medium.The lignine is then reacted during the molding operation, with hexamethylentetraamine, that acts like a crosslinking agent. Some properties of the synthetized resins were determinate; it a was found that the best formulation consist of 46,0% of resin (phenollignine), 34,5% of bagasse, 13,8% of hexamethylentetraamine, 3,7% of magnesium oxide and 2,0% of zinc stearate. |
