LOW COST MACHINABLE WOOD SUBSTITUTE FROM INDIGENOUS MATERIALS AND PROCESS FOR PREPARING THE SAME

摘要

Abstract:Conventional artificial wood substitutes normally use expensive adhesives and curing of the laminates formed therefrom necessitate prolonged thermal treatment. The resultant materials are often costly, and less expensive materials are prone to attack from rot and/or termite.The present invention provides a low cost, machinable wood substitute made from cashew nut shell liquid (CNSL), phenol, formaldehyde, caustic soda and pazatoluene sulfonic acid (PTSA), and using industrial or vegetative waste materials or cellulosic materials of low economic value. The composition thus formed are immune to action of chemicals, water or steam, does noteasily burn and termite or rot does not affect them.The invention also describes a process for preparing composites and laminates.[IN225977A1]
