Description
본 발명은 사용 후 폐기되는 물성 편차가 큰 폴리에틸렌계 수지를 수거하여 폴리프로필렌수지 함께 혼합하여 제조되는 물성 편차가 최소화되도록 조절된 재활용 수지를 제조하는 방법에 관한 것이다. The present invention relates to a method for producing a recycled resin prepared by collecting polyethylene resin having a large variation in physical properties discarded after use and mixing it with a polypropylene resin to minimize variation in physical properties.
폴리에틸렌, 폴리스티렌, 폴리프로필렌 및 폴리염화비닐과 같은 합성수지는 산업 전반의 다양한 분야에서 쓰레기 봉투, 롤백, 쇼핑백, 식품포장, 건축자재 및 가전제품 등에서 폭넓게 사용되어 왔으며, 일상생활에서 없어서는 안 될 정도의 위치를 차지하고 있다. 이러한 합성수지들은 내구성이 매우 우수하지만, 자연상태에서의 분해성이 떨어져 사용 후 폐기 시 생태계에 악영향을 끼치고 환경파괴를 야기하는 문제점이 있다. 이러한 가운데 상기 수지들을 이용한 일회용 제품의 비중이 높아지고 있어 사회적으로 큰 문제가 되고 있고 경제적 비용 상승도 초래하고 있다.Synthetic resins such as polyethylene, polystyrene, polypropylene, and polyvinyl chloride have been widely used in various fields of industry, such as garbage bags, rollbacks, shopping bags, food packaging, building materials, and home appliances, and are indispensable in daily life. occupies Although these synthetic resins have excellent durability, they have poor degradability in a natural state, which adversely affects the ecosystem and causes environmental destruction when discarded after use. In the midst of this, the proportion of disposable products using the resins is increasing, which is becoming a big social problem and causing an increase in economic costs.
2016년 기준으로 세계 플라스틱 소재 생산량은 연간 3억 4천만 톤에 이르고, 이 중에서 재활용 목적으로 수거되는 폐플라스틱 비율은 연간 생산량의 35~40% 수준이다. 여기서 15~20%는 소재 재활용으로 이용되고 나머지 20~25%는 열처리를 통한 에너지 재활용으로 활용되는 것으로 나타나고 있으며, 재활용 목적으로 수거되지 않는 60% 정도의 폐플라스틱은 모두 매립되거나 소각된다.As of 2016, the world's plastic material production reaches 340 million tons per year, of which the proportion of waste plastics collected for recycling is 35-40% of the annual production. Here, 15-20% is used for material recycling and the remaining 20-25% is used for energy recycling through heat treatment, and about 60% of waste plastics that are not collected for recycling are all landfilled or incinerated.
전 세계적으로 플라스틱 재활용은 중요한 과제로 인식되어 있어서, 플라스틱 재활용 방법은 크게 기계적, 화학적, 열적 재활용으로 나눌 수 있는데, 기계적 재활용은 수거된 플라스틱을 화학적인 구조변화 없이 물리적 형태만 변화시켜 최대한 동일한 플라스틱 원료로 선별한 뒤 재가공하는 방법이고, 화학적 재활용은 재활용 플라스틱의 분자 구조 자체를 변화해 원료로 재생하는 방법이다.Plastic recycling is recognized as an important task worldwide, and plastic recycling methods can be largely divided into mechanical, chemical, and thermal recycling. Chemical recycling is a method of changing the molecular structure of recycled plastic and reproducing it as a raw material.
이미 결합된 분자 구조를 다시 변화시키기 위해서는 반응 및 공정이 까다롭고, 다성분계 구성 물질인 수지에는 사용할 수 없으므로, 그런 이유로 화학적 재활용은 단일 물질로 구성된 PE(Polyethylene), PP(Polypropylene), PS(Polystyrene) 플라스틱에 주로 이용된다. In order to change the already bonded molecular structure again, the reaction and process are difficult, and it cannot be used for resin, which is a multi-component material. ) is mainly used for plastics.
그러나, 폴리에틸렌(PE) 소재 중에서도 고밀도 폴리에틸렌(HDPE), 중밀도 폴리에틸렌(MDPE), 저밀도폴리에틸렌(LDPE), 선형 저밀도 폴리에텔렌(LLDPE) 다양한 용도에 따른 그레이드가 구분되어 있어 이를 소재를 각각 구분하여 재활용하는 것은 현실적으로 어려움이 크다. However, among polyethylene (PE) materials, there are different grades for various uses such as high-density polyethylene (HDPE), medium-density polyethylene (MDPE), low-density polyethylene (LDPE), and linear low-density polyethylene (LLDPE). Recycling is difficult in practice.
본 발명은 상기 종래 기술의 문제점을 해결하고자 한 것으로, 폴리에틸렌계 수지 중 사용 후 폐기되는 수지를 수거하여 세척 및 재활용함으로써 진공성형 제품을 제조할 수 있는 물성강화 수지 조성물을 제공함을 기술적 과제로 한다.The present invention is intended to solve the problems of the prior art, and a technical problem is to provide a physical property-enhanced resin composition capable of producing a vacuum molded product by collecting, washing, and recycling the resin discarded after use among polyethylene-based resins.
이에 더하여, 이러한 다양한 종류의 폴리에틸렌계 수지가 혼합된 재활용 폴리에틸렌계 수지의 물성 편차를 최소화하기 위하여 전자선 조사를 통해 물성 편차를 최소화하는 것을 기술적 과제로 한다.In addition to this, in order to minimize the physical property deviation of the recycled polyethylene resin mixed with these various types of polyethylene resin, it is a technical task to minimize the physical property deviation through electron beam irradiation.

이하, 실시예 및 실험예를 통해 본 발명을 보다 구체적으로 설명한다. 그러나 이들 예는 본 발명의 이해를 돕기 위한 것일 뿐 어떠한 의미로든 본 발명의 범위가 이들 예로 한정되는 것은 아니다.Hereinafter, the present invention will be described in more detail through Examples and Experimental Examples. However, these examples are only for helping the understanding of the present invention, and the scope of the present invention is not limited to these examples in any sense.
본 발명의 일 실시형태에 따른 진공성형용 물성강화 수지 조성물은 베이스 수지와 첨가제를 포함하며, 상기 베이스 수지는 재활용 폴리에틸렌계 수지와 폴리프로필렌계 수지가 혼합된 것으로서, 상기 폴리프로필렌 수지 100 중량부를 기준으로 상기 재활용 폴리에틸렌계 수지가 30 내지 35 중량부를 포함하며, 상기 첨가제는 열가소성 전분(TPS) 0.1 내지 5.0중량부, 열경화성 수지 0.1 내지 5.0 중량부, 물성균질화제 1.0 내지 3.0 중량부, 상용화제 1.0 내지 4.0 중량부, 핵제 0.1 내지 3.0 중량부 및 가소제 2.0 내지 5.0 중량부를 포함하는 것을 특징으로 한다.The physical property-enhancing resin composition for vacuum molding according to an embodiment of the present invention includes a base resin and an additive, and the base resin is a mixture of recycled polyethylene-based resin and polypropylene-based resin, based on 100 parts by weight of the polypropylene resin. The recycled polyethylene resin includes 30 to 35 parts by weight, and the additives include 0.1 to 5.0 parts by weight of thermoplastic starch (TPS), 0.1 to 5.0 parts by weight of thermosetting resin, 1.0 to 3.0 parts by weight of a physical homogenizer, and 1.0 to 3.0 parts by weight of a compatibilizer. 4.0 parts by weight, 0.1 to 3.0 parts by weight of a nucleating agent and 2.0 to 5.0 parts by weight of a plasticizer.
본 발명의 일 실시형태에 따르면, 상기 물성강화 수지조성물은 베이스 수지는, 재활용 폴리에틸렌계 수지로 HDPE, LDPE, MDPE, LLDPE 중 어느 하나 이상을 포함한 재활용 폴리에틸렌계 수지와 폴리프로릴렌 수지가 혼합된 것이다. According to one embodiment of the present invention, in the physical property-enhancing resin composition, the base resin is a recycled polyethylene-based resin, which is a mixture of recycled polyethylene-based resin including at least one of HDPE, LDPE, MDPE, and LLDPE and polypropylene resin. .
재활용 폴리에틸렌계 수지는 저밀도 폴리에틸렌(LDPE), 중밀도 폴리에틸렌(MDPE), 고밀도 폴리에틸렌(HDPE), 선형저밀도 폴리에틸렌(LLDPE)의 4종류이다. 저밀도 폴리 에틸렌은 유연성이 있으므로 연질 폴리에틸렌이라고도 한다. 또 고밀도 폴리에틸렌은 저밀도 폴리에틸렌에 비하면 단단하므로 경질 폴리에틸렌이라고도 한다. 폴리에틸렌은 가볍고 튼튼한 플라스틱이고 고밀도 폴리에틸렌은 열탕에도 견딘다. 그러나 접착제로 접착되지 않는 것이 결점이다. There are four types of recycled polyethylene resin: low density polyethylene (LDPE), medium density polyethylene (MDPE), high density polyethylene (HDPE), and linear low density polyethylene (LLDPE). Because low-density polyethylene is flexible, it is also called soft polyethylene. High-density polyethylene is also called rigid polyethylene because it is harder than low-density polyethylene. Polyethylene is a lightweight, durable plastic, and high-density polyethylene can withstand hot water. However, it is a drawback that it does not adhere with adhesive.
폴리에틸렌은 필름으로 된 포장용 용도 및 병 모양의 여러 가지 용기로서의 용도 또 사출성형 품으로서의 용도 등, 여러가지 용도에 사용되고 있다. 이러한 다양한 종류의 폴리에틸렌계 수지는 그 용도에 따라 기본적인 물성에 차이가 크므로 사용 후 폐기되는 폴리에틸렌계 수지를 혼용하여 사출 또는 진공성형용 소재로 재활용하는데 제약이 크다.Polyethylene is used for various purposes, such as film packaging, various bottle-shaped containers, and injection molded products. Since these various types of polyethylene-based resins have a large difference in basic physical properties depending on their use, there is a great restriction in recycling them as materials for injection or vacuum molding by mixing polyethylene-based resins that are discarded after use.
본 발명에서는 이러한 다양한 그레이드의 폴리에틸렌계 수지가 가지는 물성 편차에 기인한 재활용의 어려움을 열경화성 수지를 포함한 전자선 조사 처리 및 각각의 기능을 가지는 첨가제의 조합에 의하여 해결하였다. In the present invention, the difficulty of recycling due to the variation in physical properties of polyethylene-based resins of various grades is solved by electron beam irradiation treatment including thermosetting resin and a combination of additives having respective functions.
베이스 수지의 기본 원료는 폴리프로필렌 수지이며, 사용 후 폐기된 폴리에틸렌계 수지를 수거하여 전처리한 재활용 폴리에틸렌계 수지를 혼합하여 베이스수지가 구성된다. 이 폴리에틸렌계 수지는 위의 다양한 그레이드의 폴리에틸렌계 수지가 포함될 수 있다.The basic raw material of the base resin is polypropylene resin, and the base resin is formed by mixing recycled polyethylene resin pretreated by collecting polyethylene resin discarded after use. The polyethylene-based resin may include polyethylene-based resins of various grades above.
본 발명의 일 실시형태에 따른 진공 성형용 물성강화 수지 조성물은 베이스 수지와 첨가제를 포함하며, 상기 첨가제는 열가소성 전분(TPS) 0.1 내지 5.0중량부, 열경화성 수지 0.1 내지 5.0 중량부, 물성균질화제 1.0 내지 3,0 중량부, 상용화제 1.0 내지 4.0 중량부, 핵제 0.1 내지 3.0 중량부 및 가소제 2.0 내지 5.0 중량부를 포함하는 것을 특징으로 한다.The physical property-enhancing resin composition for vacuum molding according to an embodiment of the present invention includes a base resin and an additive, wherein the additive includes 0.1 to 5.0 parts by weight of thermoplastic starch (TPS), 0.1 to 5.0 parts by weight of a thermosetting resin, and 1.0 parts by weight of a physical homogenizer. to 3,0 parts by weight, 1.0 to 4.0 parts by weight of a compatibilizer, 0.1 to 3.0 parts by weight of a nucleating agent, and 2.0 to 5.0 parts by weight of a plasticizer.
본 발명의 일 실시형태에 따르면, 상기 첨가제는 열가소성 전분(TPS) 0.1 내지 5.0 중량부를 포함한다.According to one embodiment of the present invention, the additive includes 0.1 to 5.0 parts by weight of thermoplastic starch (TPS).
본 발명의 일 실시형태에 따른 진공성형용 물성강화 수지 조성물이 첨가제로서 열가소성 전분(TPS) 0.1 내지 5.0 중량부를 포함함으로써, 내열성, 인열강도, 충격강도 및 인장강도 등의 기계적 물성이 향상될 수 있다.Mechanical properties such as heat resistance, tear strength, impact strength and tensile strength can be improved by including 0.1 to 5.0 parts by weight of thermoplastic starch (TPS) as an additive in the property-enhancing resin composition for vacuum molding according to an embodiment of the present invention. there is.
상기 열가소성 전분(TPS)이 0.1 중량부 미만의 함량으로 포함될 경우 내열성, 인열강도, 충격강도 및 인장강도 등의 기계적 물성 향상 효과가 미미하며, 상기 열가소성 전분(TPS)이 5.0 중량부를 초과의 함량으로 포함될 경우 원료 내 분산도가 낮아지는 문제가 있다.When the thermoplastic starch (TPS) is included in an amount of less than 0.1 parts by weight, the effect of improving mechanical properties such as heat resistance, tear strength, impact strength, and tensile strength is insignificant, and the content of the thermoplastic starch (TPS) exceeds 5.0 parts by weight. There is a problem that the degree of dispersion in the raw material is lowered when included as.
따라서, 본 발명에서 상기 열가소성 전분(TPS)의 함량은 5.0 중량부 이하로 사용할 경우 기계적 물성 향상 효과가 최적임을 알 수 있다.Therefore, in the present invention, it can be seen that the mechanical property improvement effect is optimal when the content of the thermoplastic starch (TPS) is used at 5.0 parts by weight or less.
본 발명의 일 실시형태에 따르면, 상기 첨가제는 열경화성 수지를 0.1 내지 5.0 중량부를 포함한다. 열경화성 수지는 펠렛으로 제조된 이후에 전자선 조사에 의하여 베이스 수지와 가교결합을 형성하여 베이스 수지의 용융 흐름 지수를 낮추고, 진공 성형 제조했을 때 충격 강도를 향상시키는데 기여를 한다. According to one embodiment of the present invention, the additive includes 0.1 to 5.0 parts by weight of the thermosetting resin. The thermosetting resin contributes to lowering the melt flow index of the base resin by forming a cross-link with the base resin by electron beam irradiation after being made into pellets and improving the impact strength when vacuum forming.
열경화성 수지는 TMPMA(3-trimethoxysilylpropyl methacrylate), TMPTMA(Trimethylolpropane Trimethacrylate), HDDA(1,6-Hexanediol diacrylate)에 중 어느 2 이상의 혼합물이다. 전자선 경화형 열경화성 수지액을 단독으로 사용하는 것보다 2가지 이상을 조합하여 사용할 경우 그에 따른 가교 효과가 더 뛰어난 것을 확인하였다. The thermosetting resin is a mixture of two or more of TMPMA (3-trimethoxysilylpropyl methacrylate), TMPTMA (trimethylolpropane trimethacrylate), and HDDA (1,6-hexanediol diacrylate). It was confirmed that the crosslinking effect was more excellent when two or more types of the electron beam curable thermosetting resin liquid were used in combination than when the liquid was used alone.
더욱, 바람직하게는 중량비로 TMPMA에 대하여 TMPTMA 또는 HDDA가 가 7:3의 비율로 혼합된 경우에 전자선 조사에 따른 MI 감소 및 충격강도 증가가 가장 우수한 것으로 나타났다. More preferably, when TMPTMA or HDDA was mixed at a weight ratio of 7:3 with respect to TMPMA, MI reduction and impact strength increase according to electron beam irradiation were found to be the best.
상기 열경화성 수지의 함량이 0.1 중량부 미만인 경우에는 전자선 조사에 의한 가교결합의 생성량이 작아 물성의 균질화 및 물성 강화 효과가 크지 않으며, 함량이 5.0 중량부를 초과하더라도 더 이상 충격 강도 등 물성의 향상 효과가 크게 나타나지 않으며 MI가 지나치게 작아져 압출 성형이 용이하지 않다.When the content of the thermosetting resin is less than 0.1 part by weight, the amount of crosslinking generated by electron beam irradiation is small, so the effect of homogenizing physical properties and strengthening physical properties is not great, and even if the content exceeds 5.0 parts by weight, the effect of improving physical properties such as impact strength is no longer It does not appear large and the MI is too small, making extrusion molding difficult.
본 발명의 일 실시형태에 따르면, 상기 첨가제는 물성 균질화제 1.0 내지 3.0 중량부를 포함한다. 물성 균질화제는 다양한 그레이드의 폴리에틸렌계 수지의 물성 편차를 상쇄시키고 폴리프로필렌 수지와 혼용할 때 압출 성형 특성을 향상시키는데 기여한다. According to one embodiment of the present invention, the additive includes 1.0 to 3.0 parts by weight of a physical homogenizer. The physical property homogenizer contributes to offset the variation in physical properties of polyethylene-based resins of various grades and improves extrusion molding properties when mixed with polypropylene resin.
본 발명에 물성 균질화제는 에틸렌 프로필렌 고무(EPM: Ethylene Propylene Rubber)를 사용한다. 천연고무를 수소화 반응시켜서 얻은 생성물과 같은 구조로서 고분자 사슬은 포화된 상태이다. Ethylene Propylene Rubber (EPM) is used as the physical property homogenizer in the present invention. It is the same structure as the product obtained by hydrogenating natural rubber, and the polymer chain is in a saturated state.
[화학식1][Formula 1]
물성 균질화제의 함량이 1.0 중량부 미만인 경우에는 물성의 균질화 및 물성 강화 효과가 크지 않으며, 함량이 3.0 중량부를 초과하더라도 더 이상 충격 강도 등 물성의 향상 효과가 크게 나타나지 않으며 MI가 지나치게 작아져 압출 성형이 용이하지 않다.When the content of the physical property homogenizer is less than 1.0 parts by weight, the effect of homogenization and strengthening of physical properties is not significant, and even if the content exceeds 3.0 parts by weight, the effect of improving physical properties such as impact strength is no longer shown, and the MI is too small, resulting in extrusion molding this is not easy

When the compatibilizer is included in an amount of less than 1.0 parts by weight, there is a problem in that compatibility between the base resin components is lowered and mechanical properties are deteriorated. The processability of the molded product may be poor.

[표 1] 전자선 조사 전후 물성 비교[Table 1] Comparison of physical properties before and after electron beam irradiation
전자선 조사에 의하여 베이스수지 성분과 열경화성 수지간 가교결합이 형성되어 멜트 인덱스(MI)가 감소되고 분자량 증가 및 충격강도가 증가된다. 이러한 멜트 인덱스의 감소에 따라 압출성형에 유리한 상태가 되었고 전자선 조사 후의 충격강도는 증가됨을 확인할 수 있었으며, EPM 함량이 3 중량부, 열경화성 수지 4중량부를 포함하는 실시예4에서 전자선 조사 이후에 MI가 가장 낮고, 충격강도 또한 가장 높은 것으로 나타났다. Cross-linking between the base resin component and the thermosetting resin is formed by electron beam irradiation, thereby reducing the melt index (MI), increasing molecular weight, and increasing impact strength. As the melt index decreased, it became advantageous for extrusion molding, and it was confirmed that the impact strength after electron beam irradiation was increased. It was found to be the lowest and the impact strength was also the highest.
