CAST-IN-PLACE CUSHIONING MATERIAL INCLUDING FOAMED PET CHIPS AND ITS CONSTRUCTION METHOD
본 발명은 섬유보강재, 발포페트칩 및 계면활성재를 포함하여 이루어진 현장 타설형 완충재 및 그 시공방법에 관한 것이다. 상기 섬유보강재는 수거된 폐 보온덮개를 분쇄하여 5~20mm로 가공된 강화섬유 100 중량부와, 에틸렌-옥텐 공중합체 또는 스틸렌-디엔 공중합체, 또는 이들의 혼합물인 고무수지 25 내지 30 중량부 및 유동화제로 액상의 리그닌술폰산나트륨 3 내지 5 중량부를 포함하고, 상기 발포페트칩은 페트병을 분쇄한 페트플레이크에 발포제를 혼합하여 압축 성형하며, 상기 계면활성는 소듐라우릴설페이트인 것이다.
The present invention relates to a cast-in-place type cushioning material comprising a fiber reinforcement material, foamed PET chips, and a surfactant, and a construction method thereof. The fiber reinforcement material includes: 100 parts by weight of reinforcing fiber processed into 5 to 20 mm by crushing collected waste thermal cover; 25 to 30 parts by weight of a rubber resin that is an ethylene-octene copolymer or a styrene-diene copolymer, or a mixture thereof; and 3 to 5 parts by weight of liquid sodium lignin sulfonate as a fluidizing agent. The foamed PET chips are compression-molded by mixing PET flakes obtained by crushing PET bottles with a foaming agent, and the surfactant is sodium lauryl sulfate.
