Chemical and Mechanical Properties for Rosin-based Hybrid Resins

Abstract

The increasing concern for the protection of the environment, through the use of renewable natural resources, has led in the last decades to the realization of a number of natural polymers or hybrids to be able to replace petroleum-based polymeric materials. Rosin is a low-cost wood resin extracted from conifers. In this paper, based on FTIR and Raman analyses, the spectra of natural Rosin resin and some hybrid resins with volume proportions of 45, 55 and 65% Rosin were studied. Some mechanical properties such as modulus of elasticity, elongation at break, tensile strength were determined from stress-strain diagrams obtained from tensile stress. Increasing the volume proportion of Rosin leads to a decrease in stiffness and strength properties and obtaining a visco-elastic behavior.

Effect of Nano-Silver Solution Microcapsules Mixed with Rosin-Modified Shellac Microcapsules on the Performance of Water-Based Coating on Andoung Wood (Monopetalanthus spp.)

“…The FTIR of melamine-formaldehyde resin-coated rosin-modified shellac microcapsules are shown in Figure 1. The distinct vibrational peak at 2980 cm −1 was the -CH 2 group, which was a rosin compound [41]. This indicates the presence of the core materials.…”
