Abstract

A substance that is used to join two materials together is called adhesive and most of the adhesives used in many industries are based on non-renewable petro-chemical resources such as phenol/formaldehyde and chemical polyurethane and contain a volatile organic compound (VOCs). As such, this heavy reliance on petroleum and the adverse human health effects of emissions have created an urgent need for renewable resource-based, environmentally-friendly adhesives. In this scenario, an alternative adhesives is produced. Therefore, the focus of this original scientific study is to explore the mechanical properties of adhesive produced with Euphorbia Trigon Mil latex (ETML) and Enset starch as a potential polymeric adhesive. The thermosetting adhesive was prepared from modified enset starch (mS) and modified ETML (mETML) with curing temperature of 900C (90-mS-mETML), 1000C(100-mS-mETML), 1100C(110-mS-mETML),1200C (1200C-mS- mETML), 1300C(1300C-mS-mETML), 1400C(1400C mS-mETML) curing time (1,3,6,9,12 hr.) and mixing ratio (100:0,75:25,50:50,25:75,0:100 w/w%) were evaluated. The curing process was carried out in a conventional heating system. In the case of ETML modification, LA (Lactic Acid) was used as a modifier and the process was carried out by using polycondensation reaction. The quality of thermosetting adhesive (mS-mETML) was assessed by determining the mechanical properties. According to mechanical tests, effect of temperature, time, and mixing ratio was studied. The use of excessive-high temperatures can not only increase the curing speed, and also using the higher amount of mETML or ms influences the strength. For this situation, homo-polymerization response beat crosslinking. The mS-mETML cured at 1100C performed better mechanical properties based on lap shear strength with values of 1.24Mpa for glass and 0.94 for wood respectively. And 1100C was the maximum crosslinking temperature. The result indicated the potential use of latex from ETM and starch from Enset as an alternative to producing adhesive.
