폐플라스틱을 이용한 기능성 강화플라스틱의 물성평가

The reinforced plastics to make unit cell as rain storage tank were prepared with waste thermoplastics such as poly ethylene, poly propylene and reinforcing agents. The physical properties such as the strength of tensile, elongation, flexural, impact, hardness and strain of the prepared plastics were investigated. For this purpose, the inorganic reinforcing agents such as talc, calcium carbonate, glass fiber and mixing agent which were blended by them were added to thermoplastics(PE/PP) in order to the reinforced plastics. At this time, the hydrophilic inorganic reinforcing agents were reformed to have the hydrophobic property because they didn't mix each other. The physical properties of a prepared reinforced plastic were varied according to the types and adding amounts of the reinforcing agents. That is, the properties of reinforced plastics such as tensile, flexural, impact, hardness and strain strengths were increased along adding reinforcing agents while its elongation strength was decreased. The physical property of fiber type reinforced plastics was higher than that of particle type if a single reinforcing agent use. However, the physical property of composite reinforced plastic was the highest among them due to add particle and glass fiber characters. The plastic in this work didn't distort in compressive strength test for short and long term load according to underground buried. From the results, the plastic in this work could be used for rain storage unit cell which was reported from previous work.
