This study examined the beneficial effects of fibrillar cellulosic additives derived from sugar beet pulp and wood pulp on the performance of aminoplastic particleboard adhesives. The results showed that within certain boundaries, the use of these additives can lead to longer open time, higher internal bond strengths, and reduced resin consumption.
Aminoplastic particleboard adhesives are reactive, inexpensive and well established in industry. Even so, potential adhesive savings are of interest due to a number of reasons. Therefore, fibrillar cellulosic additives derived from sugar beet pulp and from wood pulp were examined with regard to beneficial effects on adhesive performance. Particleboards were prepared with, varying adhesive content and board density. For a proper processing of the additives, focus is laid on the critical process steps during particle resination. As shown by the results, the use of fibrillar cellulosic additives may enable longer open time, higher internal bond strengths and reduced resin consumption only within well-defined boundaries.
