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.
