Description
본 발명은 폐 후단조합램프의 재생방법에 관한 것으로서, 더욱 상세하게는 폐 후단조합램프를 분쇄하여 강 부분을 분리하고 여기에 내열성이 우수한 ABS 수지를 일정량 첨가하여 혼합하고 컴파운딩하므로써 충격강도, 열변형온도 및 신율이 향상된 재생수지를 제조할 수 있는 폐 후단조합램프의 재생방법에 관한 것이다.The present invention relates to a method for regenerating a waste rear stage combined lamp, and more particularly, to separate the steel part by pulverizing the waste rear stage combined lamp, adding a certain amount of ABS resin having excellent heat resistance, mixing and compounding the impact strength and heat. The present invention relates to a recycling method of a closed rear stage combined lamp capable of producing a recycled resin having improved deformation temperature and elongation.
램프는 크게 렌즈부와 하우징부로 구성되어 있으며, 렌즈는 폴리메틸메타크릴레이트로 이루어지고, 하우징부는 ABS 수지로 이루어져 있다. 이같은 재질로 이루어진 램프를 재질별 분리작업없이 재생할 경우 내부에 존재하는 은 분사물(silver spray)성분과 접합부의 핫 멜트 접착제로 인해 내열성, 내충격성 및 신율 등의 물성이 특히 취약해지는 문제가 있었다.The lamp is largely composed of a lens part and a housing part, the lens is made of polymethyl methacrylate, and the housing part is made of ABS resin. When a lamp made of such a material is reproduced without separate work for each material, physical properties such as heat resistance, impact resistance, and elongation due to the silver spray component and the hot melt adhesive of the junction existed particularly weak.
이에따라 지금까지는 램프를 재생하지 않고 전량 폐기하므로써 환경문제를 일으키고 비용을 소모하고 있었다.Accordingly, until now, all lamps have been recycled without being recycled, causing environmental problems and costing them.
본 발명은 상기와 같은 폐 후단조합램프를 재생하는 데 있어서의 문제점을 해결하기 위하여 램프 전체를 분쇄하고 강 부분만을 분리한 다음 플라스틱 분쇄물에 고내열성의 ABS 수지를 첨가하여 컴파운딩하므로써 충격강도, 열변형온도 및 신율이 향상된 재생재료로 제조할 수 있는 폐 후단조합램프의 재생방법을 제공하는 데 그 목적이 있다.In order to solve the problems in regenerating the above closed rear combination lamp, the present invention crushes the whole lamp, separates only the steel part, and adds a high heat-resistant ABS resin to the plastic pulverized compound, thereby improving the impact strength. It is an object of the present invention to provide a method for regenerating a closed rear stage combined lamp which can be manufactured from recycled materials having improved heat deflection temperature and elongation.
본 발명은 폐 후단조합램프를 0.1∼10㎜ 크기로 분쇄하는 공정, 장착 볼트를 제거하는 공정 및 분쇄된 플라스틱 1∼95 중량％와 ABS 수지 5∼99 중량％를 혼합하여 컴파운딩하는 공정으로 이루어진 폐 후단조합램프의 재생방법을 그 특징으로 한다.The present invention comprises a process of pulverizing the closed rear stage combined lamp to a size of 0.1 to 10 mm, a process of removing the mounting bolt, and a compounding process of mixing 1 to 95% by weight of crushed plastic and 5 to 99% by weight of ABS resin. It is characterized by the regeneration method of the closed rear stage combined lamp.
이와같은 본 발명을 더욱 상세하게 설명하면 다음과 같다.The present invention will be described in more detail as follows.
본 발명은 자동차 폐 후단조합램프를 분쇄하여 분쇄물에 ABS 원료수지를 혼합하여 압출기를 사용하여 압출재생하는 방법에 관한 것이다.The present invention relates to a method of extruding and regenerating by using an extruder by pulverizing the automobile rear end combination lamp to mix the ABS raw resin to the pulverized product.
우선, ABS계 후단조합램프를 평균입경이 0.1∼10㎜되도록 분쇄한다. 분쇄는 저속분쇄기나 고속분쇄기와 같은 기계적 분쇄기를 사용한다. 만일, 분쇄물의 크기가 상기 범위를 벗어나면 정량 혼합이 불가능하거나 개질제와의 상용성이 떨어지는 문제가 있다.First, the ABS series stage combined lamp is pulverized so that the average particle diameter is 0.1 to 10 mm. Grinding uses a mechanical mill such as a slow mill or a high mill. If the size of the pulverized product is out of the above range, there is a problem in that quantitative mixing is impossible or compatibility with the modifier is inferior.
그 다음에 장착 볼트를 분리해내는데, 장착 볼트는 강으로서 고분자와 분리는 용이하다. 장착 볼트를 분리하는데는 자력분리기 등을 사용할 수 있다.The mounting bolts are then removed, which is easy to separate from the polymer as steel. A magnetic separator can be used to remove the mounting bolts.
강 재료를 분리시킨 다음, ABS와 폴리메틸메타크릴레이트 및 핫 멜트로 이루어진 분쇄물에 ABS 원수지를 첨가한다. ABS는 매트릭스인 스티렌-아크릴로니트릴 공중합체(SAN)에 고무를 보강시킨 열가소성 수지로서, SAN은 내열성 향상을 위해 α-메틸 스티렌 또는 말레이미드 등과 같은 공중합물을 포함할 수 있다.The steel material is separated and then the ABS raw resin is added to the mill consisting of ABS, polymethyl methacrylate and hot melt. ABS is a thermoplastic resin reinforced with a styrene-acrylonitrile copolymer (SAN), which is a matrix, and the SAN may include a copolymer such as α-methyl styrene or maleimide to improve heat resistance.
혼합시 플라스틱 분쇄물 1∼95 중량％와 ABS 원수지 5∼99 중량％ 되도록 혼합할 수 있다.At the time of mixing, 1 to 95% by weight of the plastic pulverized product and 5 to 99% by weight of the ABS raw resin can be mixed.
폴리메틸메타크릴레이트와 ABS는 상용성이 우수하므로 물성은 전반적으로 함량비에 의존하여 두 수지간의 중간물성을 발현하게 된다. 그러므로, 램프 전체를 분쇄하여 재생수지를 제조할 경우 폴리메틸메타크릴레이트의 존재로 인해 비중, 굴곡탄성율, 인장강도 및 경도는 ABS에 비해 증가하고, 반면에 충격강도, 열변형온도 및 신율과 같은 물성이 감소하는 것은 불가피하다.Since polymethyl methacrylate and ABS have excellent compatibility, the physical properties are generally expressed depending on the content ratio to express intermediate properties between the two resins. Therefore, the specific gravity, flexural modulus, tensile strength and hardness increase compared to ABS due to the presence of polymethyl methacrylate when the recycled resin is manufactured by crushing the entire lamp, whereas impact strength, heat deformation temperature and elongation are increased. It is inevitable that the physical properties decrease.
본 발명에서는 이를 해결하기 위하여 상기와 같이 ABS 원수지를 첨가하는 것이다. 첨가되는 ABS 원수지로는 열변형온도 80∼130℃인 것을 사용한다.In the present invention to solve this problem is to add the ABS raw resin as described above. As the raw ABS resin to be added, one having a heat deflection temperature of 80 to 130 ° C is used.
분쇄물과 ABS 원수지를 혼합하고 이를 1축 또는 2축 압출기 등 통상의 열가소성 수지용 압출기를 사용하여 압출하되, 가공온도 200∼250℃에서 행하는 것이 바람직하다.The pulverized product and the ABS raw resin are mixed and extruded using a conventional thermoplastic resin extruder such as a single screw or twin screw extruder, but is preferably performed at a processing temperature of 200 to 250 ° C.
한편, 압출시 필요에 따라 산화방지제, 자외선안정제, 착색제 및 충전제 등의 첨가제를 배합할 수 있다.On the other hand, additives such as antioxidants, ultraviolet stabilizers, colorants and fillers may be blended as needed during extrusion.
이하, 본 발명을 실시예에 의거하여 상세히 설명하면 다음과 같은 바, 본 발명이 실시예에 의해 한정되는 것은 아니다.Hereinafter, the present invention will be described in detail with reference to the following Examples, but the present invention is not limited by the Examples.

The pulverized product was uniformly mixed with a Henschel mixer so as to have a 75:25 weight ratio with ABS having a heat deflection temperature of 95 ° C.
