LIGNIN EPOXY COMPOSITES

This paper presents some possibilities for the use lignin/epoxy resins in blends and composites with epoxy resins. A compatibility study was carried out by optical and electron microscopy, viscosimetric determi nations and thermo-optical analysis in order to establish optimum synt hesis conditions of molding mass (cast resins). Lignin/epoxy composite s including various fillers (lead soap, alum earth, talc, chalk, sand, trihydrate aluminium oxide, glass fibers), palsticizer (dibutylphthal ate and polyester C6) and pigments (iron-oxide and titanium dioxide) h ave been obtained. Lignin/epoxy composites are characterized by good d ielectric, mechanical and adhesive properties. These composite materia ls can be used in the electronics industry.
