چکیده

روغن پالم اپوکسید شده (EPO) کمک فرایندی سازگار با محیط‌زیست، زیست تخریب‌پذیر و به‌نسبت مقرون به‌صرفه است. در این مطالعه، جایگزینی EPO با روغن آروماتیک (AO)، روغن استخراج شده‌ی آروماتیک تقطیر شده‌ی اصلاح شده (TDAE) و روغن پالم اصلاح‌نشده (PO) در کائوچوی استایرن بوتادی‌ان (SBR) بررسی‌شده است. مشخصات پخت، خواص مکانیکی، مقاومت سایشی و خواص گرمازایی آمیزه حاوی EPO با نمونه‌های استاندارد حاوی روغن‌های آروماتیک مقایسه شد. آمیزه‌های لاستیکی حاوی EPO، بهبود خواص مکانیکی شامل مدول، استحکام کششی و ازدیاد طول در نقطه پارگی از خود نشان دادند. این اتفاق به بهبود پراکنش پرکننده‌ها در بستر کائوچو و برهم‌کنش بین پرکننده و کائوچو برمی‌گردد. افزون‌بر این، استفاده از EPO در مقادیر کم باعث مقاومت سایشی، جهندگی و گرمازایی قابل‌توجهی می‌شود. EPO در آمیزه‌های لاستیکی به‌عنوان یک ماده اولیه تجدیدپذیر است که می‌تواند جایگزین روغن‌های نفتی در کاربردهای مختلف شود. این پژوهش، مسیر جدیدی را برای آمیزه‌های لاستیکی با عملکرد عالی در مصارف مهندسی گوناگون باز می‌کند.
