일반적으로, 석유화학 제품인 합성수지는 내약품성, 투명성, 유연성 및 강성 등 뛰어난 물성과 특징 때문에 여러 분야에서 광범위하게 사용되고 있다. In general, synthetic resins, which are petrochemical products, are widely used in various fields because of their excellent physical properties such as chemical resistance, transparency, flexibility and rigidity.
그러나 최근 대량으로 발생하고 있는 각종 수지포장재 필름 및 시트, 비닐류 및 플라스틱 용기 등과 같은 폐합성수지 제품들로 인한 환경오염은 사회적 문제로 대두되고 있다.However, environmental pollution caused by waste synthetic resin products such as various resin packaging films and sheets, vinyls and plastic containers, which are occurring in a large amount recently, has emerged as a social problem.
전술한 문제를 해결하기 위해, 최근 비닐봉투 사용금지 규제와 같은 환경보호 차원의 노력과 더불어 폐기 시 자동으로 분해되는 분해성 수지에 대한 연구 및 개발이 활발하게 진행되고 있는 실정이다. In order to solve the above-described problem, research and development on degradable resins that are automatically decomposed when discarded, along with efforts to protect the environment, such as the ban on the use of plastic bags, are being actively conducted.
분해성 수지로는 토양 중에 존재하는 미생물에 의해 분해되는 생분해성 수지와, 태양광의 자외선에 의해 분해되는 광분해성 수지로 분류할 수 있다. Degradable resins can be classified into biodegradable resins that are decomposed by microorganisms present in the soil and photodegradable resins that are decomposed by ultraviolet rays of sunlight.
그러나 전술한 분해성 수지 중 상용화되고 있는 종래 광분해성 수지의 경우 광분해 기능 이외에는 별도의 기능을 가지지 못하기 때문에 사용 범위가 극히 제한적일 수밖에 없는 문제점이 있었다.However, in the case of the conventional photodegradable resin commercially available among the above-described decomposable resins, there is a problem that the range of use is extremely limited because it does not have a separate function other than the photolysis function.

다만, 본 발명의 본질적인(intrinsic) 기술적 사상은 이하에서 설명되는 실시형태에 의해 그 실시 가능 형태가 제한된다고 할 수는 없고, 본 발명의 본질적인(intrinsic) 기술적 사상에 기초하여 통상의 기술자에 의해 이하에서 설명되는 실시형태를 치환 또는 변경의 방법으로 용이하게 제안될 수 있는 범위를 포섭함을 밝힌다. However, the intrinsic technical idea of the present invention cannot be said to be limited by the embodiments to be described below, and the intrinsic technical idea of the present invention is given below by a person skilled in the art. It turns out to cover the range that can be easily proposed by a method of substitution or change of the embodiment described in FIG.
또한, 이하에서 사용되는 용어는 설명의 편의를 위하여 선택한 것이므로, 본 발명의 본질적인(intrinsic) 기술적 사상을 파악하는 데 있어서, 사전적 의미에 제한되지 않고 본 발명의 기술적 사상에 부합되는 의미로 적절히 해석되어야 할 것이다. In addition, since the terms used below are selected for convenience of description, in grasping the intrinsic technical idea of the present invention, it is not limited to the dictionary meaning and is appropriately interpreted as a meaning consistent with the technical idea of the present invention. Should be.
본 발명에 따른 광분해성 수지는 35~45중량%의 탄산칼슘, 5~10중량%의 견운모, 15-25중량%의 실리카(SiO2), 30~42중량%의 폴리프로필렌(PP), 4~10중량%의 폴리에틸렌(PE), 스테아린 또는 스테로이디올레인(지방산) 1~3중량%를 포함한다. The photodegradable resin according to the present invention is 35 to 45% by weight of calcium carbonate, 5 to 10% by weight of sericite, 15 to 25% by weight of silica (SiO 2 ), 30 to 42% by weight of polypropylene (PP), 4 It contains ~ 10% by weight of polyethylene (PE), stearin or steroidiolane (fatty acid) 1 to 3% by weight.
탄산칼슘은 미립자 형태로 제공되며, 탄산칼슘이 45중량%를 초과하면 상대적으로 폴리프로펠렌(PP) 및 폴리에틸렌(PE)의 부족으로 가공성이 저하되면서 제조되는 성형물에서 균열이 발생할 수 있으며, 탄산칼슘이 35중량% 미만이면 상대적으로 폴리프로펠렌(PP) 및 폴리에틸렌(PE)의 사용량이 많아지기 때문에 광분해성이 떨어지게 된다.Calcium carbonate is provided in the form of fine particles, and if calcium carbonate exceeds 45% by weight, the processability is relatively deteriorated due to a lack of polypropene (PP) and polyethylene (PE), and cracks may occur in the formed product. If it is less than 35% by weight, the amount of polypropene (PP) and polyethylene (PE) is relatively large, so that the photodegradability is deteriorated.
견운모는 탄산칼슘과 마찬가지로 미립자 형태로 제공되되, 견운모가 10중량%를 초과하면 목적하는 이상의 항균력 및 항균 지속성을 얻을 수 있으나 상대적으로 탄산칼슘 및 폴리프로펠렌(PP) 및 폴리에틸렌(PE)의 부족으로 가공성이 저하된다. 그리고 견운모가 5중량% 미만이면 견운모를 첨가해 얻고자 하는 기능, 즉 항균력 및 항균 지속성을 기대하기 어렵다. Similar to calcium carbonate, sericite is provided in the form of fine particles, but if sericite exceeds 10% by weight, the desired antibacterial activity and antibacterial persistence can be obtained, but due to a relatively lack of calcium carbonate and polypropene (PP) and polyethylene (PE). The workability decreases. In addition, if sericite is less than 5% by weight, it is difficult to expect functions to be obtained by adding sericite, that is, antibacterial activity and antibacterial persistence.
그리고 실리카(SiO2)가 15중량% 미만이면 원료들의 균질화가 어렵고, 실리카(SiO2)가 25중량%를 초과하더라도 더 이상의 효과를 기대하기 어렵다.And if the silica (SiO 2 ) is less than 15% by weight, homogenization of the raw materials is difficult, and even if the silica (SiO 2 ) exceeds 25% by weight, it is difficult to expect further effects.
또한, 폴리프로필렌(PP)이 42중량%를 초과하면 분해시간이 증가하게 되고, 폴리프로필렌(PP)이 30중량% 미만이면 분해시간이 단축될 수 있으나 가공성이 저하된다. In addition, if the polypropylene (PP) exceeds 42% by weight, the decomposition time increases, and if the polypropylene (PP) is less than 30% by weight, the decomposition time may be shortened, but processability deteriorates.
폴리에틸렌(PE)은 폴리프로필렌(PP)의 첨가량에 대하여 4~10중량% 범위 내에서 첨가되는 것이 바람직한데, 폴리에틸렌(PE)가 상기 범위 내로 첨가되었을 때 제조되는 성형물의 내충격성이 우수하며 경도가 유지된다. Polyethylene (PE) is preferably added within the range of 4 to 10% by weight based on the amount of polypropylene (PP) added. When polyethylene (PE) is added within the above range, it has excellent impact resistance and hardness. maintain.
그리고 스테아린 또는 스테이로이드올레인이 3중량%를 초과하면 첨가량 대비 그 효과가 미미하고, 스테아린 또는 스테이로이드올레인이 1중량% 미만이면 펠릿화가 어려워진다. In addition, when the amount of stearin or steroid olein exceeds 3% by weight, the effect is insignificant compared to the amount added, and when the amount of stearin or steinoid olein is less than 1% by weight, pelletization becomes difficult.
하기에는 전술한 바와 같이 형성된 광분해성 수지 조성물의 제조방법을 설명한다.Hereinafter, a method of preparing the photodegradable resin composition formed as described above will be described.
먼저, 스크루가 내장된 통상의 가열로에 스테아린 또는 스테로이디올레인 1~3중량%을 배합해 장입한 후, 스테아린 또는 스테로이디올레인을 50℃에서부터 70℃까지 단계적으로 온도를 상승시켜 결정체를 제조한다(단계 S1). First, in a conventional heating furnace with a built-in screw, 1 to 3% by weight of stearin or steroidiolane is mixed and charged, and then the temperature is increased step by step from 50°C to 70°C to obtain crystals. It is prepared (step S1).
여기서, 50℃ 미만의 온도에서부터 스테아린 또는 스테로이디올레인을 반응시키면 반응시간이 길어지게 되고, 70℃를 초과하면 스테아린 또는 스테로이디올레인이 결정화되지 못하고 녹게 된다. Here, reaction time of stearin or steroidiolein at a temperature of less than 50°C increases the reaction time, and if it exceeds 70°C, stearin or steroydiolane cannot be crystallized and dissolved.
전술한 바와 같이 스테아린 또는 스테로이디올레인이 결정화시켜 결정체 제조되면(단계 S1), 다음으로 탄산칼슘과 실리카(SiO2) 및 견운모를 입자화 한다.(단계 S2).As described above, when stearin or steroidiolane is crystallized to produce crystals (step S1), calcium carbonate, silica (SiO 2 ), and sericite are then granulated (step S2).
탄산칼슘과 실리카(SiO2) 및 견운모를 입자화하기 위해서는, 단계(S1)에서 제조된 스테아린 또는 스테로이디올레인 결정체에 35~45중량%의 탄산칼슘, 중량15~25중량%의 실리카, 5~10중량%의 견운모를 배합해 장입한다. In order to granulate calcium carbonate, silica (SiO 2 ) and sericite, 35 to 45% by weight of calcium carbonate, 15 to 25% by weight of silica, 5 to the stearin or steroidiolane crystals prepared in step (S1). It is charged by mixing ~10% by weight of sericite.
그리고 탄산칼슘 및 견운모가 입자화 되도록 110~130℃에서 가열반응 시킨다. 이때 가열반응 온도가 110~130℃ 범위를 벗어나면 탄산칼슘과 실리카 및 견운모의 입자화가 어렵게 된다.And it is heated and reacted at 110~130℃ so that calcium carbonate and sericite are made into particles. At this time, if the heating reaction temperature is out of the range of 110 to 130°C, it becomes difficult to make particles of calcium carbonate, silica, and sericite.
전술한 바와 같이 탄산칼슘과 실리카 및 견운모가 입자화 되면(단계 S2), 다음으로 용융수지를 제조한다(단계 S3).When the calcium carbonate, silica, and sericite are granulated as described above (step S2), a molten resin is then prepared (step S3).
용융수지는 입자화 된 탄산칼슘 및 견운모에 30~42중량%의 폴리프로필렌(PP), 4~10중량%의 폴리에틸렌(PE)을 배합해 장입시킨 상태 하에서 60~70℃, 120~130℃ 및 250~260℃의 온도로 순차적으로 입자화된 탄산칼슘과 실리카 및 견운모와 폴리프로필렌(PP) 및 폴리에틸렌(PE)를 반응시켜 용융수지를 제조한다. The molten resin is 60-70°C, 120-130°C, and in a state in which 30-42% by weight of polypropylene (PP) and 4-10% by weight of polyethylene (PE) are added to the granulated calcium carbonate and sericite. A molten resin is prepared by reacting sequentially granulated calcium carbonate, silica, sericite, polypropylene (PP) and polyethylene (PE) at a temperature of 250 to 260°C.
여기서, 입자화된 탄산칼슘과 실리카 및 견운모와 폴리프로필렌(PP) 및 폴리에틸렌(PE)가 상기 범위의 온도 내에서 단계적으로 반응되었을 때 균질화 된 용융수지를 얻을 수 있다. Here, when the granulated calcium carbonate and silica, sericite, polypropylene (PP) and polyethylene (PE) are reacted stepwise within the above range, a homogenized molten resin can be obtained.
한편, 전술한 단계(S3)에서 용융수지가 제조되면, 다음으로 융용수지를 펠렛화 한다(단계 S4).On the other hand, if the molten resin is produced in the above-described step (S3), the molten resin is then pelletized (step S4).
용융수지의 펠렛화는 당 업계에서는 공지의 기술로 상세한 설명은 생략한다. 일례로 용융수지는 가늘고 긴 형태로 압출되는데, 이렇게 압출된 압축물은 냉각된 후 소정의 길이로 절단되어 펠렛화 된다. The pelletization of the molten resin is a technique known in the art, and a detailed description thereof will be omitted. For example, the molten resin is extruded in a thin and elongated form, and the extruded compact is cooled and then cut into a predetermined length to be pelletized.
이렇게 펠렛화 된 본 발명에 따른 광분해성 수지 조성물은 180~220℃에서 용융되고, 사출 또는 압축 또는 압착되어 목적하는 성형물이 제조되게 한다.The photodegradable resin composition according to the present invention, thus pelletized, is melted at 180 to 220° C., and is injected, compressed, or compressed to produce a desired molding.
이와 같은 본 발명에 따른 수지 조성물은 광분해성이 우수할 뿐만 아니라 첨가된 견운모에 의해 우수한 항균력과 항균 지속성 및 신선도 유지성을 갖게 된다. The resin composition according to the present invention is not only excellent in photodegradability, but also has excellent antibacterial activity, antibacterial persistence, and freshness retention by the added sericite.
