Lignocellulosic composites |
摘要 |
Lignocellulosic-based woodfiber-plastic composite products containing a pesticidal amount of calcium borate is resistant to attack by wood destroying fungi and insects. The preferred calcium borates are the calcium polytriborates having a CaO:B<SUB>2</SUB>O<SUB>3 </SUB>molar ratio of about 2:3 and calcium hexaborates, having a CaO:B<SUB>2</SUB>O<SUB>3 </SUB>ratio of 1:3. Composites can be produced by combining the calcium borate with particles of the lignocellulosic material and the thermoplastic resin binder, and heating and extruding the resultant mixture through a die to form the composite product.
