The rise in demand for the use of adhesive in key industrial applications such as packaging, automotive and construction industries signal the need for using material with lower to no negative impact on the environment.

摘要

The rise in demand for the use of adhesive in key industrial applications such as packaging, automotive and construction industries signal the need for using material with lower to no negative impact on the environment. This research paper investigates the use of bio-adhesives with favorable degradable qualities as alternatives to solvent-based synthetic adhesives commonly found in the industry. This material is extracted from a plant-based latex and is processed at two temperature parameters of 110 °C and 150 °C to yield a naturally sourced bio-adhesive material. Measurements and analyses using a rheometer were performed under controlled conditions, to assess bio-adhesive behaviour and characteristics within the specified temperature parameters. To ensure continuous consistency and reliability of the data produced, operational conditions were kept constants for all rheological measurements executed. The results from the rheometer demonstrated that the bio-adhesive material exhibits viscoelastic behaviour, and this is influenced by the frequency of the applied shear.
