Optimisation of Biobased Adhesives Synthesis From Gelatine and Euphorbia Abysinica Latex
Résumé
Abstract This investigation is an attempt of extracting bio based adhesives from gelatine and plant latex to overcome the negative effects of synthetic adhesive. The bio based adhesive was extracted with mixing plant resins from Euphorbia Abyssinica as additives with gelatine through optimisation. The factors in the synthesis of bio based adhesive were temperature, time, and concentration with level of 50-60oc, 30–60 Min, and 50–75% gelatine; and the optimum level was found 500C, 45min, and 75% respectively with optimum result of 282.12 gram gel strength. The characteristics of the resulted bio adhesive were 6.25cp, 6.85, and 11.53% of viscosity, pH, and moisture content values respectively. The performance of the bio adhesive was examined interms of peel and shear strength and it has an average value of 6.645N/mm and 198.1N respectively. This research is effective way of overcoming environmental burden from synthetic adhesives by the production of bio adhesives from gelatine and plant resin.
