Abstract

Mechanical properties of the commingled waste plastics filled with waste newspaper were studied. To improve adhesion at the interface, abietic acid was used. Tensile strength increased with fiber concentration. However the abietic acid did not have any influence on the strength. Tensile strain and impact strength as well decreased with increasing fiber level in the composite, but the abietic acid at low level of concentration with low level of fiber dramatically improved both properties. The reason seemed to be attributed to double-chemical nature of abietic acid.

혼합폐플라스틱과 섬유소로서 폐신문지를 혼합하여 복합체를 구성하고 그 기계적인 물성을 조사하였다. 수지-수지 및 수지-섬유소 사이의 계면접착력을 증대시키고자 섬유소와 친화성을 가진 아비틱산을 소량 첨가하였다. 섬유소의 투입량이 많아질수록 인장강도는 플라스틱자체보다 저하되었으며 아비틱산은 강도에 좋은 영향을 주지 못하였다. 파단신장률 및 충격강도는 섬유소만의 투입량에 따라서는 감소하였으나, 섬유소가 적은 양이고 아비틱산이 적게 포함되어 있을 경우에 놀라운 상승을 나타내었다. 물성의 향상은 아비틱산의 화학적인 양면성에 기인한다고 여겨진다.
