Abstract

In this study, a nontoxic aldehyde with high boiling point entitled glyoxal was used for reaction with urea and kraft lignin to prepare a green adhesive entitled urea- lignin- glyoxal (LUG). The prepared LUG resin was used in PARTICLEBOARD manufacturing. Then, the influence of nano clay addition on various properties of PARTICLEBOARD made from LUG resin was investigated. For this reason, the kraft lignin (10 wt%) was used instead of second urea in urea- glyoxal resin synthesis. After synthesizing LUG resin in acidic condition and measuring physicochemical properties of the prepared resins, the prepared LUG resin was mixed with the 0.5, 1 and 1.5% of nano clay via mechanically stirring for 5 min at room temperature. Then, the prepared resin was used in PARTICLEBOARD manufacturing. The physicochemical properties of the prepared resins such as viscosity, gelation time, solid content and density as well as physical (water absorption) and mechanical (internal bond strength and flexural properties) properties of manufactured panels were measured according to standard methods. Also, x-ray diffractometry (XRD) was used to investigate the distribution of nano clay in LUG resin. The results of physicochemical test indicated that gelation time of the LUG resin is slower than that of UF resin. Addition of nano caly from 0.5 to 1.5% accelerated the gelation time of the prepared resins whereas the fastest gelation time was related to the LUG resin containing 1.5% nano caly. Moreover, XRD ANALYSIS indicated that nano clay could well be separated when mixing with LUG resin. Based on obtained result, the addition of nano clay significantly decreased the water absorption content of the manufactured panels. The internal bond strength and flexural strength of the panels was increased by adding the nano clay. Finally, it must be noted that the addition of nano clay had no significant effect on flexural modulus of the manufactured panels.
