Özet:

In the study, some technological properties of composites obtained by using expanded perlite in wood-plastic composites were investigated. Expanded perlite, polypropylene (PP), sawdust, corn cob shavings and MAPP interface agent were used for the preparation of polymer composites. Twin screw extruder was used for composite production. The amount of lignocellulosic materials in the composites was kept constant and the amount of expanded perlite was gradually increased and the effect of the amount of perlite on the properties of the composites was investigated. The mechanical (bending, tensile and shock resistance), physical (surface hardness), thermal (TGA and DSC) and SEM analyzes of the test samples prepared from the obtained composites were carried out and their technological properties were investigated. According to the results of the analysis, it was understood that as the expanded perlite ratio in the composite material increased, the results of flexural strength, tensile strength and modulus of elasticity increased, but the shock resistance decreased. In addition, it was understood that the MAPP material added to bond between lignocellulosic and plastic improves the mechanical properties of the composites. According to the results obtained, it was understood that the expanded perlite added to the composites improved the technological properties of the wood plastic composite material.
