목탄의 제조 과정 중 얻어지는 목타르의 활용방안을 모색코자 페놀수지에 목타르를 혼합하여 합판을 제조하여, 물리적, 기계적 및 포름알데히드 방출성능을 조사하였다. 목타르를 혼합하여 제조된 합판의 경우, 목타르를 혼합하지 않은 합판에 비해 물리적, 기계적인 면에서 별다른 감소를 보이지 않았으며, 인장전단 접착력은 비내수, 내수 모두 목타르의 혼합으로 인하여 오히려 향상되는 것으로 나타났다. 또한 포름알데히드 방출량에서도 목타르의 첨가는 방출량을 감소시키는 것으로 나타났다.
This study was performed to find a new use of wood tar from the manufacturing process of wood charcoal. Plywoods made of phenol adhesives mixed with wood tar were manufactured, and physical, mechanical properties and formaldehyde emission were investigated. Plywoods made of phenol adhesives mixed with wood tar were almost same as an original phenol adhesive in physical and mechanical properties and tensile-shear adhesive strength of the plywood was higher than the original one in both non-waterproof and waterproof tests. Formaldehyde emission was lower as the amount of wood tar increased in phenol adhesive.
