Sleeper for rail road using waste plastic
The present invention relates to a sleeper for a railroad, which is manufactured by using waste plastic. More specifically, the sleeper for a railroad, which is manufactured by using waste plastic, is molded by extruding mixed materials with an extruder. The mixed materials are obtained by mixing: 30-40 parts by weight of recycled waste plastic in which waste polypropylene and waste polyethylene are mixed; 25-35 parts by weight of household waste plastic in which waste plastic including PE, PP, PVC, and PET is mixed without being classified according to types of waste plastic; 25-35 parts by weight of a filler including pond ash or steel slag; 3-5 parts by weight of an anti-static agent; and 5-8 parts by weight of an antifoaming agent. The sleeper for a railroad, which is manufactured by using waste plastic, has the maximum bending load of 3,400-50,355 N, a thermal expansion coefficient of 1.0×10^-5, screw retention force of 872 N, flexural creep deformation of 0.14%, maximum tensile strength of 18.2-19.3 MPa, 6.37-7.42% of stain during destruction, and a modulus of 1,020-1,113 MPa. According to the present invention, it is possible to prevent environmental pollution and recycle resources.
본 발명은 폐플라스틱을 이용한 철도용 침목에 관한 것으로, 특히 폐폴리프로필렌과 폐폴리에틸렌을 혼합한 재활용 폐플라스틱 30 내지 40 중량부; PE, PP, PVC, PET을 포함하는 폐플라스틱들 종류별로 분별되지 않고 혼합된 생활 폐플라스틱 25 내지 35 중량부; 폰드 애쉬 또는 제강 슬래그를 포함한 필러 25 내지 35 중량부; 대전방지제 3 내지 5 중량부; 및 소포제 5 내지 8중량부;를 혼합한 혼합 재료를 압출기로 압출하여 성형된다. 본 발명의 폐플라스틱을 이용한 철도용 침목은 3,400N 내지 50,355N의 굴곡최대하중, 1.0×10의 길이선 열팽창계수, 872N의 나사못 유지력, 0.14%의 굴곡크리프 변형, 18.2 내지 19.3MPa의 최대 인장강도와, 6.37~7.42 %의 파단시 스트레인과, 1020~1113MPa의 모듈러스를 가진다.
