Fire Performance and Technological Properties of Plywood Prepared by with PMUF Adhesive Modified with Organic Phosphate.

Abstract

This study focuses on assessing the effectiveness of phosphate-modified phenol-melamine-urea-formaldehyde (PMUF) resin in plywood fabrication by using Eucalypatus as core veneer and gurjun sp. as face veneer. The PMUF resin synthesis was with the ratio of F:P:M:U at 4.6:2.0:0.42:0.29 by using Tricresyl phosphate at laboratory scale.12mm ply board was prepared by using the modified PMUF resin with some additive in the glue formulation. The mechanical and fire properties were carried as per respective Indian standard. FTIR, NMR, DSC-TGA analysis was carried for resin characterization for functional group confirmation. In overall from the study the data revels that the plywood made by using the phosphate modified glue shows satisfactory fire performance and mechanical properties which confirms as per IS:5509 (2000) requirement. The addition of organic phosphate enhances the plywood's fire resistance without compromising its physical and mechanical attributes, demonstrating its potential for improved safety and performance in diverse applications.
