| چکیده | ||
| با توجه به افزایش آلودگی های زیست محیطی ناشی از تجمع ضایعات و زباله های حاوی پلیمرهای نفتی پایدار، جایگزین نمودن این پلیمرها با استفاده از پلیمرهای زیستی و اصلاح مشکلات و کمبودهای آنها در فرایند تولید و در محصولات نهایی امری بااهمیت می باشد. در این پژوهش به بررسی امکان تولید چندسازه پلی لاکتیک اسید-پوسته شالی با ویژگی های قابل قبول و همچنین تاثیر استفاده از پرکننده های معدنی کندسوز کننده آلومینیوم تری هیدرات (ATH) و هیدروکسید منیزیم (MDH) برروی خواص فیزیکی و حرارتی چندسازه تولیدی پرداخته شده است. نتایج نشان داد که دانسیته چندسازه پلی لاکتیک اسید-پوسته شالی نسبت به چندسازه های ساخته شده با پلیمرهای پایه نفتی پلی پروپیلن (PP) و پلی اتیلن دانسیته بالا (HDPE) بیشتر بود و افزودن پرکننده های معدنی کندسوز کننده سبب افزایش دانسیته چندسازه شد. همچنین افزودن پرکننده های معدنی کندسوز کننده سبب کاهش میزان جذب آب و واکشیدگی ضخامت آنها گردید بطوریکه از این لحاظ با نمونه های حاوی پلیمرهای پایه نفتی قابل قیاس بود. نتایج آنالیز وزن سنجی حرارتی (TGA) نشان داد که افزودن پرکننده های معدنی کندسوز کننده سبب کاهش دما در محل پیک های افت وزنی چندسازه و همچنین ملایم تر شدن شیب افت وزنی نسبت به افزایش دما شده است. | ||

| چکیده [English] | ||
| Considering the increase of environmental pollutant resulted from agglomerating rubbish and wastes containing stable petroleum-based polymers, substitution of these polymers with bio-polymers and solving their problems and defects in the production process as well as the final products is an important topic. In this study, the possibility of the production of poly lactic acid (PLA)-rice husk composite with acceptable properties, and also the effect of using flame retardant mineral fillers of aluminum three hydrates (ATH) and magnesium di-hydroxide (MDH) on physical and thermal properties of the produced composite were investigated. Results indicated that the density of PLA-rice husk composite was higher than petroleum-based polymers composites (PP/HDPE-rice husk composites); and flame retardant mineral fillers addition led to an increase in the composite density. Also, flame retardant mineral fillers addition decreased the composite water absorption and thickness swelling, in a way that they were comparable with petroleum-based polymers composites. Results of thermal gravimetric analysis (TGA) showed that flame retardant mineral fillers addition also decreased the temperature of the composite weight loss curve peaks, and the weight loss rate toward temperature rising. | ||
