PRODUCTION OF THE POLYMER COMPOSITES WITH MDI FROM SOME INDUSTRIAL WASTES
 
Nowadays, alternative studies are becoming widespread to meet the raw material needs. Economical polymer raw materials are produced by using domestic, renewable resources and wastes. In this study, polymer composites were produced by mixing commercially supplied polyol and 4,4’-methylenediphenyl diisocyanate (MDI) in certain proportions with industrial factory wastes. The fillers were obtained by evaluating the salt factory wastes in Çankırı and boron factory wastes supplied in Eskişehir. The chemical and physical properties of composite materials were examined and characterization processes were conducted. Changes in the polymer matrix structure were compared by using different proportions of colemanite, ulexite and tincal ore from boron factory wastes by mass. In addition, the effects of clay and salt factory wastes on the thermal and mechanical properties of the produced composite were also investigated. According to the results, the use of high rates of fillers increased the density and thermal conductivity coefficient of the composites. Although it weakened its mechanical strength and elasticity properties, it improved the non-flammability of the polymer composites. Generally, the use of industrial factory wastes at 5% or less by mass did not negatively affect the crosslink structure, porosity, mechanical and thermal properties of polymer composites. However, when more than 10% filler is used, it has been observed that closed pore structures increase. The individual effects of the additives on the composite can also improve some desired properties depending on the intended use.
