Description

Wood composites with crosslinked acrylic copolymer, which includes DBT-DL (di-n-butyl tin dilaurate) as a crosslinking acceletor and stabilizer, were exposed to a brown-rot (TYP), a white-rot fungus (COV) and termite for investigation of the effects of the amount of DBT-DL on the biological resistance. The bare DBT-DL significantly affected TYP and termite as inhibitor of biodegradation but 4.994 mg of DBT-DL to 1g of wood was required for decay resistance to COV.<BR>When DBT-DL coexisted together with crosslinking copolymers, 6.075 mg of DBT-DL to 1g of wood was required for surpression of the attack by TYP, and the weight loss for termite attack was about 10% under the same condition. DBT-DL was assumed to reduce its toxicity against TYP and termites by the coexistance of the copolymer. The coexistance of these copolymers and DBT-DL, however, was considered to improve the safety of the composite because of prevention of the chemical elution into water.
