합성목재(Wood Plastic Composite, WPC)는 데크 자재뿐만 아니라, 현재 PVC, Aluminum 및 steel 제품이 주류를 이루고 있는 창호 및 건자재 시장에 제품 자체가 가지고 있는 다양한 용도의 적용 가능성과 양호한 가공성 그리고 친환경성을 무기로 빠른 속도로 그 시장을 확대할 전망이다. 지금까지 외부용의 자재로 잘 알려진 WPC의 데크(deck) 자재 외에도 창호, 실내 가구재, 바닥재, 방음벽 등의 거의 모든 인테리어 분야의 용도에도 활발한 개발이 이루어지고 있다.Wood Plastic Composite (WPC) is not only a deck material, but also has a wide range of applications, good processability, and eco-friendliness that the product itself has in the window and construction materials market, where PVC, aluminum and steel products are the mainstay. is expected to expand the market at a rapid pace. In addition to the deck material of WPC, which is well known as an exterior material so far, active development is being made for almost all interior fields such as windows and doors, interior furniture materials, flooring materials, and soundproof walls.
다양한 건축자재로 사용되고 있는 합성목재(Wood Plastic Composite, WPC)는 천연목재와 방부목재가 갖는 단점을 보완하는 것과 동시에, 실내외의 마감재로서 우수한 물성을 가진다는 점에 있어서 오늘날 그 수요가 늘고 있다. Wood Plastic Composite (WPC), which is used as a variety of building materials, is increasing in demand today in that it compensates for the shortcomings of natural wood and preservative wood and has excellent properties as an indoor and outdoor finishing material.
이와 같은 합성목재는 목분(wood flour)과 합성수지를 주원료로 하는데, 그 중 목분은 합성목재에서 무늬 및 질감과 같은 천연목재가 가진 고유의 특성이 나타나도록 하는 역할을 한다. 그리고 목분은 주로 목재의 가공 작업에서 발생되는 톳밥, 대팻밥과 같은 부산물이 된다. 허나 이와 같은 방식으로 얻어지는 목분의 경우, 각기 다른 비중과 섬유길이를 갖는 다양한 수종으로부터 수집되는 것에 의하여 동일한 물성을 갖는 합성목재의 생산에 어려움이 따른다. 그리고 여전히 이와 같은 목분을 원료로 만들어지는 합성목재에서 제품 가공성, 휨 강도 및 충격 강도 등을 포함한 다양한 물성의 개선이 요구되고 있다.Such synthetic wood uses wood flour and synthetic resin as main raw materials, and among them, wood flour plays a role in making the unique characteristics of natural wood such as patterns and textures appear in synthetic wood. And wood flour is a by-product such as tobap and shavings, which are mainly generated in the processing of wood. However, in the case of wood flour obtained in this way, it is difficult to produce synthetic wood having the same physical properties as it is collected from various species having different specific gravity and fiber length. In addition, improvement of various physical properties, including product processability, flexural strength, and impact strength, is required in synthetic wood made from such wood powder as a raw material.
기존 원료인 합성수지가 가지는 난분해성, 미세 플라스틱 발생에 따른 환경 오염 등의 문제가 대두되면서 탄소발생량을 줄이고 친환경적인 소재에 대한 관심과 수요가 증가되고 있다. 따라서, 합성목재의 생산에서도 기존 합성수지의 일부를 친환경 소재로 대체하게 되면 수요자의 요구에 부응할 수 있고 친환경 소재로서 제품 경쟁력을 높일 수 있으므로 이에 대한 연구개발이 지속적으로 이루어지고 있다. As problems such as the difficulty of degradability of synthetic resins, which are existing raw materials, and environmental pollution caused by the generation of microplastics have emerged, interest and demand for eco-friendly materials that reduce carbon emissions are increasing. Therefore, even in the production of synthetic wood, if a part of the existing synthetic resin is replaced with an eco-friendly material, it is possible to meet the demands of consumers and increase the product competitiveness as an eco-friendly material.

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 Bio-PE를 포함하는 합성목재 펠릿 조성물은 베이스 수지, Bio-PE, 목분, 필러, 결합보조제, 상용화제 및 경화성 수지액을 포함하는 합성목재 펠릿 조성물에 있어서, 상기 베이스 수지 100 중량부에 대하여, 상기 Bio-PE 10 내지 40 중량부, 상기 목분은 150 내지 250 중량부를 포함하고, 상기 필러는 25 내지 50 중량부, 결합보조제 1 내지 15 중량부, 상용화제는 5 내지 15 중량부, 상기 경화성 수지액은 2 내지 10 중량부를 포함하고, 상기 경화성 수지액은 3-(acryloyloxy)-2-hydroxypropyl methacrylate(AHM)로 표면 처리한 Trimethylolpropane ethoxylate triacrylate(TMPET)와 촉매로서 benzylquinoxalinium hexafluoroantimonate(BQH)를 포함하며, 상기 합성목재 펠릿 조성물은 전자선이 조사되어, 상기 목분과 수지가 가교 결합된 상태인 것을 특징으로 한다.In the synthetic wood pellet composition comprising Bio-PE according to an embodiment of the present invention, the synthetic wood pellet composition comprising a base resin, Bio-PE, wood powder, filler, bonding aid, compatibilizer and curable resin solution, the Based on 100 parts by weight of the base resin, 10 to 40 parts by weight of the Bio-PE, 150 to 250 parts by weight of the wood flour, and 25 to 50 parts by weight of the filler, 1 to 15 parts by weight of a binding aid, and 5 parts by weight of a compatibilizer to 15 parts by weight, the curable resin solution contains 2 to 10 parts by weight, the curable resin solution is trimethylolpropane ethoxylate triacrylate (TMPET) surface-treated with 3-(acryloyloxy)-2-hydroxypropyl methacrylate (AHM) and benzylquinoxalinium as a catalyst It contains hexafluoroantimonate (BQH), and the synthetic wood pellet composition is irradiated with an electron beam, characterized in that the wood powder and the resin are cross-linked.
본 발명의 일 실시형태에 따르면, 상기 Bio-PE를 포함하는 합성목재 펠릿 조성물이 포함하는 베이스 수지는 열가소성 수지일 수 있으며, 예를 들어 폴리에틸렌(PE), 고밀도 폴리에틸렌(HDPE), 저밀도 폴리에틸렌(LDPE), 폴리프로필렌(PP), 폴리스티렌(PS) 및 폴리에틸렌 테레프탈레이트(PET)로 이루어진 군으로부터 선택된 어느 하나 이상인 것을 특징으로 한다.According to one embodiment of the present invention, the base resin included in the synthetic wood pellet composition comprising Bio-PE may be a thermoplastic resin, for example, polyethylene (PE), high density polyethylene (HDPE), low density polyethylene (LDPE) ), polypropylene (PP), polystyrene (PS) and polyethylene terephthalate (PET) characterized in that at least one selected from the group consisting of.
상기 Bio-PE를 포함하는 합성목재 펠릿 조성물은 베이스 수지, Bio-PE, 목분, 필러, 결합보조제, 상용화제 및 경화성 수지액을 포함하며, 상기 베이스 수지 100 중량부에 대하여, 상기 Bio-PE 10 내지 40 중량부, 상기 목분은 150 내지 250 중량부를 포함하고, 상기 필러는 25 내지 50 중량부, 결합보조제 1 내지 15 중량부, 상용화제는 5 내지 15 중량부, 상기 경화성 수지액은 2 내지 10 중량부를 포함한다.The synthetic wood pellet composition containing the Bio-PE includes a base resin, Bio-PE, wood flour, filler, bonding aid, compatibilizer and a curable resin solution, with respect to 100 parts by weight of the base resin, the Bio-PE 10 to 40 parts by weight, the wood flour includes 150 to 250 parts by weight, the filler is 25 to 50 parts by weight, binding aid 1 to 15 parts by weight, compatibilizer 5 to 15 parts by weight, and the curable resin solution is 2 to 10 parts by weight including parts by weight.
상기 Bio-PE는 탄소 중립 및 친환경 소재에 대한 시장의 요구에 부응하기 위함이다. Bio-PE는 사탕수수에서 얻은 착즙에서 설탕을 정출하고 남은 최종산물로 제조되는 폴리에틸렌계 소재이다. Bio-PE는 원료의 가격이 상대적으로 비싸고, 내구성, 내후성이 상대적으로 낮고 목분 및 기타 성분과 결합력이 낮아 많은 함량으로 사용하는데 제약이 많은 소재이다. 따라서 Bio-PE는 올레핀계 수지 100 중량부에 대하여 10 내지 40 중량부를 포함한다.The Bio-PE is to meet the market demand for carbon neutral and eco-friendly materials. Bio-PE is a polyethylene-based material manufactured from the final product remaining after sugar crystallization from the juice obtained from sugar cane. Bio-PE is a material that has many restrictions on its use in large amounts because the raw material price is relatively high, durability and weather resistance are relatively low, and the binding force with wood flour and other components is low. Accordingly, Bio-PE contains 10 to 40 parts by weight based on 100 parts by weight of the olefinic resin.
상기 목분은 유기필러의 하나로, 목분(wood flour), 목펠렛(wood pellet), 목섬유(wood fiber) 또는 지분일 수 있으며, 경우에 따라 2가지 이상을 혼합하여 사용할 수 있다.The wood flour is one of the organic fillers, and may be wood flour, wood pellet, wood fiber, or stock, and in some cases, a mixture of two or more may be used.
상기 목분은 칩, 셰이빙 및 톱밥과 같은 재활용 물질을 미세한 가루의 형태로 파쇄시켜 만들어질 수 있다. 목분은 20 내지 120 메시(mesh)일 수 있으며, 길이 대 직경의 비는 3:1 내지 5:1일 수 있다. 목분의 입자 크기 또는 길이 대 직경의 비가 상기 범위를 벗어나는 경우, 동일 중량의 배합이라도 목분 입자의 개수에 차이가 있어 혼련이 어렵거나, 합성목재로 제조시에 기계적 강도가 떨어지는 문제가 있다.The wood flour may be made by crushing recycled materials such as chips, shavings and sawdust into a fine powder. The wood flour may be between 20 and 120 mesh, and the ratio of length to diameter may be between 3:1 and 5:1. When the particle size or length-to-diameter ratio of the wood powder is out of the above range, there is a problem in that kneading is difficult due to a difference in the number of wood powder particles even when the mixture of the same weight is used, or the mechanical strength is deteriorated when manufactured with synthetic wood.
상기 유기필러의 원료는 침엽수 또는 활엽수에서 얻을 수 있으며, 활엽수는 펜토산(pentosan)의 함유량이 침엽수보다 많이 함유하고 있어 화학적 경합을 방해하므로 침엽수인 것이 효과적이다.The raw material for the organic filler can be obtained from conifers or hardwoods, and since the content of pentosan is higher than that of conifers, it prevents chemical competition, so it is effective to use softwoods.
