The Application Development of Plant-Based Environmental Protection Plasticizer
Journal Title: Biotechnology Journal International - Year 2013, Vol 3, Issue 3
Abstract
Present research is aimed towards designing and development of environmental protection plasticizers using the fractionation heavy component in the industrial production of corn stalks as raw material. The plant-based rubber oil (PBRO) plasticizers are the reactants of the dihydric alcohols (Polyols) in heavy component with phthalic anhydride (PA) (the molar ratio of Polyols/PA as 2 : 1) at the temperature range of 180 -190ºC. The main advantage is that this substance does not contain any of the sixteen hazardous substances of PAHs (polycyclic aromatic hydrocarbons) and 38 hazardous substances of PAHs (polycyclic aromatic hydrocarbons) recorded in EU REACH regulation. In plasticization of NBR, the dosage of PBRO can reach 25 phr (parts per hundreds of rubber), but the plasticizing effects of PBRO is inferior to common rubber oil (paraffin oil, naphthenic oil, aromatic hydrocarbon oil and Dioctyl phthalate). In plasticization of SBR, the maximum amount of PBRO is 20 phr. Although the mechanical properties decrease; the aging resistance and thermal stability (the temperature of maximum weight losses of PBRO as 302ºC) are slightly higher than that of common rubber oil.
