| Summary: | 博士 === 國立臺灣科技大學 === 材料科學與工程系 === 107 === The modified recycled rubber / PP thermoplastic elastomer was prepared by dynamic vulcanization and blending with the activated agent, accelerator, solubilizer, crosslinking agent, recycled rubber and PP. The effects of the amount of powder and pp and the crosslinking agent, the tensile properties, tensile strength, impact strength and the microstructure of the samples were observed by scanning electron microscopy using the amount of the accelerator, activator and solvent. It was found that the compatibilizer could effectively disperse the 120 mesh waste powder into the pp in the same manner, and obtain the rubber/pp thermoplastic elastomer tear section to be homogeneous, and discuss the best ratio of the powder and PP.
On the other hand, we use the features, such as excellent adsorption performance, natural, environmentally friendly and biodegradable characteristics of natural biodegradable polymer materials, and then find the optimal formula/conditions gelled microspheres technology to be facilitated as a green biodegradable substrate material for the adsorbent waste materials. Furthermore, an adsorption material (Regenerated Tire Carbon Black; RCB) with dispersion and modification techniques was established, and chemical modification/grafting (-COOH surface functional groups). The modified/not RCB and CTS can be uniformly dispersed in the composite in SA substrate to improve compatibility, to reduce dosage and adsorption capacity, thus to form a green biodegradable waste material through an adsorbent material gelation. It will both help Taiwan's green industry to be more competitive and meet the demands of sustainable development.
