Sound-absorbing panel capable of absorbing broadband and method for manufacturing a sound-absorbing panel
The present invention relates to a sound absorption panel, which comprises: a step of generating a first mixing material in which recycled polyester and low melting (LM) polyester are mixed at the weight ratio of 20-60% : 80-40%; a step of generating a second mixing material in which recycled polyester and LM polyester are mixed at the weight ratio of 80-40% : 20-60%; a step of mixing and heating the first mixing material and the second mixing material; and a step of fabricating a sound absorption panel by forming a front surface portion at a predetermined thickness and shape by performing compression molding. The front surface portion has a surface area and at least one curved area of which one portion is formed in a groove shape at the surface area. The curved area may comprise: a first curve which is the boundary of the upper portion; a second curve which is the boundary of the lower portion; and a groove area provided between the first curve and the second curve. Therefore, the present invention can be conveniently installed.
본 발명은 흡음 패널에 관한 것으로, Recycle polyester와 LM polyester(Low Melting Polyester)를 20 내지 60% : 80 내지 40%의 중량비로 혼합한 제1 혼합 재료를 생성하는 단계, Recycle polyester와 LM polyester를 80 내지 40% : 20 내지 60%의 중량비로 혼합한 제2 혼합 재료를 생성하는 단계, 제1 혼합 재료 및 제2 혼합 재료를 혼합하여 가열하는 단계 및 압축 성형을 수행하여 기 설정된 두께 및 형상으로 전면부를 형성하여 흡음 패널을 제조하는 단계를 포함하고, 상기 전면부는 표면 영역 및 상기 표면 영역에서 일부가 홈 형태로 형성된 적어도 하나의 굴곡 영역이 형성되되, 상기 굴곡 영역은, 윗부분의 경계인 제1 굴곡, 아랫부분의 경계인 제2 굴곡 및 상기 제1 굴곡 및 상기 제2 굴곡 사이의 홈 영역을 포함할 수 있다.
