Development and optimization of a bio-based adhesive from euphorbia trigon latex reinforced with alumina for sustainable wood bonding applications
The environmental and health concerns associated with petroleum-based synthetic adhesives, particularly their non-biodegradability and emission of volatile organic compounds (VOCs), have been widely recognized.

| description | The environmental and health concerns associated with petroleum-based synthetic adhesives, particularly their non-biodegradability and emission of volatile organic compounds (VOCs), have been widely recognized. As a result, increased attention has been given to the development of sustainable, bio-based alternatives. However, natural adhesives have often been limited by inadequate mechanical strength, low thermal stability, and poor durability. In this study, a bio-adhesive was formulated from Euphorbia trigon latex, an underutilized, non-edible, and drought-tolerant plant, by reinforcing it with alumina (Al₂O₃) to enhance its performance characteristics. Improvements in structural integrity and thermal resistance were targeted while maintaining environmental sustainability. A Central Composite Design (CCD) under Response Surface Methodology (RSM) was employed to optimize the formulation parameters. The effects of latex concentration, alumina loading, and mixing time were systematically analyzed. An optimized formulation comprising 40 % latex, 30 % alumina, and a mixing time of 30 min was obtained. Under these conditions, a lap shear strength of 7.7 MPa, a viscosity of 3585 mPa·s, and a thermal decomposition temperature exceeding 400 °C were achieved. These results indicate that the developed bio-adhesive can serve as a viable and eco-friendly alternative to synthetic adhesives for wood bonding, particularly in regions where cost-effective and locally sourced materials are desired. |
