The present invention relates to a fibrous plastic composite material and a method for manufacturing the same, more specifically, the fiber which can be used for a long time without changing the product in the natural environment of the interior and exterior due to excellent strength, weather resistance, dimensional stability, flame retardancy, mold resistance, etc. It relates to a plastic composite and a method for producing the same.
최근 천연목재에 대한 소비자의 선호도가 크게 증가하고 있으며, 또한 천연목재의 벌목에 따른 이산화탄소 증가로 인한 환경파괴 우려가 증폭되면서 천연목재를 대체할 수 있는 소재 개발에 대한 목소리가 높아지고 있다. 특히, 천연목재의 수요가 많은 건축자재 경우 더욱 그러하다. Recently, consumers' preference for natural wood is increasing greatly, and as the concern about environmental destruction due to the increase of carbon dioxide due to the felling of natural wood is amplified, voices for developing materials that can replace natural wood are increasing. This is especially true for building materials, where demand for natural wood is high.
이러한 배경에서 최근 천연목재와 유사한 질감과 외관을 가진 합성목재 및 이러한 합성목재를 제조할 수 있는 방법에 관한 연구가 많이 이루어지고 있다.Recently, many studies have been conducted on synthetic wood having a texture and appearance similar to natural wood and a method of manufacturing such synthetic wood.
종래의 합성목재는 원목을 얇게 자른 다음 일측면이나 양측면에 착색하여 건조시키고 접착제를 이용하여 필름 등을 부착하여 건조시킨 다음 소정 길이로 절단하여 사용하도록 구비된 합판 형태와, 원목이나 폐목을 가루로 분쇄한 다음 다량의 수지를 첨가한 후 가열 압착시켜 만드는 MDF(Medium Density Fiberwood) 또는 왕겨나 목분에 합성수지를 혼합 압출 또는 사출하여 성형시킨 성형목재로 구분되며, 특히 MDF는 천연 무늬목이나 비닐 무늬목을 부착시켜 용도에 맞게 가공해서 사용할 수 있다.Conventional synthetic wood is cut into thin wood and then colored and dried on one side or both sides, dried by attaching a film, etc. using an adhesive, and then cut into a predetermined length, plywood form and wood or waste wood to powder It is divided into MDF (Medium Density Fiberwood) made by crushing and adding a large amount of resin, followed by heat compression, or molded wood formed by mixing or extruding synthetic resin in chaff or wood powder. Especially, MDF is attached with natural veneer or vinyl veneer. It can be processed and used according to the application.
또한, 최근의 합성목재는 폴리염화비닐, 폴리스티렌, 아크릴로니트릴-부타디엔-스티렌공중합체, 폴리에틸렌, 폴리프로필렌 등의 열가소성 수지에 목분, 왕겨분, 펄프 분말, 볏짚 분말, 갈대 등 소위 리그노셀룰로오스계 분말을 혼합한 조성물을 압출가공한 후 적당한 형상 및 크기로 제조된다. 특히, 폴리염화비닐과 리그노셀룰로오스계 분말에 의한 합성목재는 가공성이 우수하고 건자재로서 필수적인 난연성도 가지며 가격이 저렴하여 수요가 확대되고 있다.In recent years, synthetic wood has been used in thermoplastic resins such as polyvinyl chloride, polystyrene, acrylonitrile-butadiene-styrene copolymer, polyethylene, polypropylene, etc. The composition mixed with the powder is extruded and then manufactured into a suitable shape and size. In particular, synthetic wood by polyvinyl chloride and lignocellulosic powder is excellent in workability, has essential flame retardancy as a building material, and is inexpensive and demand is expanding.
그러나, 위와 같은 종래 합성목재는 무늬목과 판제 간에 수축 팽창이 쉽게 일어나며, 햇빛, 빗물 및 외부 수분 등의 영향으로 인해 부착된 무늬목이 분리되는 문제가 있다. 또한, 쉽게 깨지거나 갈라지고, 뒤틀리는 현상이 발생하여 형태가 변화할 뿐만 아니라, 곰팡이나 병충해로 인해 부패되어, 합성목재를 자주 교체해야 하는 문제점이 있으며, 특히 환경이 열악한 외부에서 사용할 경우 교체주기가 더욱 빨라지므로 비용소모가 크다. However, the conventional synthetic wood as described above has a problem that shrinkage and expansion easily occurs between the veneer and the plate, the attached veneer is separated due to the influence of sunlight, rainwater and external moisture. In addition, it is easily broken, cracked, distorted, not only changes in shape, but also decayed due to mold or pests, there is a problem that often needs to replace the synthetic wood, especially when used in a poor environment outside the replacement cycle It's faster, so it's expensive.

Fibrous plastic composite of the present invention is 20 to 80 mesh (fiber) 52 to 64% by weight, thermoplastic resin 24 to 32% by weight, reinforcing agent 5 to 7% by weight, binder 1 to 3% by weight, lubricant 1 to 3% by weight And it comprises 0.1 to 1% by weight of the antimicrobial agent. Moreover, 3 to 5 weight% of coloring agents can be further added and used.
본 발명에 있어서, 상기 섬유질은 합성수지 재료를 대체하여 이용할 수 있는 소재로서, 구입이 손쉽고 가격이 저렴할 뿐만 아니라 분말로 가공이 용이하고 환경오염의 염려가 없으며, 인장강도, 굽힘강도, 충격강도 등의 강도가 우수한 특징이 있다. 이러한 섬유질은 농산폐기물, 목재, 목재 생산물, 비목재 제지섬유, 짚, 잔디, 갈대, 인피 섬유를 가진 줄기, 잎 섬유, 재활용지 또는 대나무 등에서 선택하여 사용할 수 있으며, 농산폐기물로서 옥수수대, 수수대, 볏짚, 야자수 열매 껍질, 해조류, 땅콩껍질 등을 사용할 수 있으나, 이에 한정되지 않는다. In the present invention, the fiber is a material that can be used to replace the synthetic resin material, not only easy to purchase and low price, but also easy to process into powder, there is no concern of environmental pollution, such as tensile strength, bending strength, impact strength The strength is excellent. These fibers can be selected from agricultural waste, wood, wood products, non-wood paper fiber, straw, grass, reeds, stems with bast fibers, leaf fibers, recycled paper or bamboo, and can be used as agricultural waste, cornstalks, sorghum, Rice straw, palm bark, algae, peanut shell, etc. may be used, but is not limited thereto.
본 발명에서 상기 섬유질은 70℃ 이상인 건조기 내에 투입되어 수분 함량이 2 중량% 이하가 되도록 건조시키는데, 이렇게 수분을 조절하면 바인더를 첨가하지 않고 섬유질 플라스틱 복합재를 제조할 수 있으며, 살균효과도 가지는 장점이 있다. 한편, 섬유질의 수분 함량이 2 중량% 초과이면 제품 성형 시 성형기 내에서 폭발성을 갖기 때문에 위험하다. In the present invention, the fiber is added to the dryer 70 ℃ or more to dry the moisture content is 2% by weight or less, by controlling the moisture can be prepared fibrous plastic composite without adding a binder, has the advantage of having a sterilization effect have. On the other hand, if the moisture content of the fiber is more than 2% by weight is dangerous because it has an explosive property in the molding machine when molding the product.
상기 섬유질은 20~80 메쉬(mesh)로 분쇄하여 52~64 중량%로 이용하는데, 바람직하게는 30~70 메쉬로 분쇄하여 54~62 중량%로 사용하는 것이 좋다. 이때, 섬유질의 함량이 52 중량% 미만인 경우에는 섬유질 외에 다른 성분함량이 상대적으로 높아지기 때문에 단가의 절감측면에서 바람직하지 못할 뿐만 아니라 강도가 저하될 수 있으며, 함량이 64 중량% 초과인 경우에는 보강재 및 결합제와 결합되지 않는 섬유질이 발생하여 강도가 저하될 수 있다. The fiber is pulverized to 20 to 80 mesh (mesh) to use 52 to 64% by weight, preferably pulverized to 30 to 70 mesh is preferably used at 54 to 62% by weight. In this case, when the content of the fiber is less than 52% by weight, other components besides the fiber are relatively high, which is not only undesirable in terms of cost reduction, but also the strength may be reduced. When the content is more than 64% by weight, the reinforcement and Fibers that do not bind with the binder may be generated to lower the strength.
본 발명에서 상기 열가소성수지는 내열성, 내후성이 뛰어나고 투명성을 가지며, 합성목재의 가공성을 높이는 역할을 한다. 본 발명에서 상기 열가소성수지는 폴리알킬렌으로서 당해 기술이 속하는 분야의 통상적인 소재를 사용할 수 있으나 이에 한정되지 않으며, 바람직하게는 폴리에틸렌, 폴리프로필렌 및 이들의 혼합물로 이루어진 군에서 선택된 중합체이며, 보다 바람직하게는 폴리에틸렌과 폴리프로필렌을 3 : 4 내지 4 : 3 중량부로 혼합하여 사용하는 것이 좋다. 본 발명에서 상기 열가소성수지는 24~32 중량%를 사용하는 것이 바람직한데, 함량이 24 중량% 미만일 경우에는 제품 성형 시 합성목재의 탄력성 및 가공성이 떨어질 수 있으며, 함량이 32 중량% 초과이면 유기 섬유질의 함량이 상대적으로 줄어들어 강도가 저하되고, 제품 가격이 상승할 수 있다.In the present invention, the thermoplastic resin has excellent heat resistance, weather resistance and transparency, and serves to increase the workability of synthetic wood. In the present invention, the thermoplastic resin may be a polyalkylene, but may be a conventional material in the art to which the art belongs, but is not limited thereto. Preferably, the thermoplastic resin is a polymer selected from the group consisting of polyethylene, polypropylene, and mixtures thereof, and more preferably. Preferably, polyethylene and polypropylene may be mixed and used in an amount of 3: 4 to 4: 3 parts by weight. In the present invention, it is preferable that the thermoplastic resin is used in an amount of 24 to 32% by weight. If the content is less than 24% by weight, the elasticity and processability of the synthetic wood may be reduced during the molding of the product, and if the content is more than 32% by weight, the organic fiber The content of can be relatively reduced, leading to lower strength and higher product prices.
본 발명에서 상기 보강제는 폴리에틸렌과 폴리프로필렌의 강도뿐만 아니라, 난연성도 증강시킨다. 이때 보강제는 무기물질인 탄산칼슘에 고온에서 열가소성수지와 분산제, 산화방지제, 내열안정제 등을 용융하여 일정한 칩 상태로 되어있는 성형제품을 사용할 수 있으며, 바람직하게는 용융지수가 0.8인 탄산칼슘 85±1 중량%, 용융지수가 4.0인 폴리머 10±1 중량% 및 난연제 등의 첨가제 5±1 중량%를 포함하여 이루어진 펠릿 형태로, 용융점은 105±5℃ 이고, 비중은 1.9±0.1 이며, 입자크기는 3.2±1Φ의 제품을 사용하는 것이 좋다. 상기 보강제는 5~7 중량% 사용하는 것이 바람직하며, 보강제의 함량이 5 중량% 미만인 경우에는 폴리에틸렌의 강도를 높이기 어려울 수 있고, 7 중량% 초과일 경우에는 폴리프로필렌의 강도를 약화시킬 수 있다. In the present invention, the reinforcing agent enhances flame retardancy as well as strength of polyethylene and polypropylene. At this time, the reinforcing agent may be a molded product in which a predetermined chip state is melted by melting a thermoplastic resin, a dispersant, an antioxidant, a heat stabilizer, etc. at a high temperature with calcium carbonate, which is an inorganic material, and preferably 85 ± calcium carbonate having a melt index of 0.8 ±. Pellets made up of 1% by weight, 10 ± 1% by weight of a polymer having a melt index of 4.0 and 5 ± 1% by weight of an additive such as a flame retardant, having a melting point of 105 ± 5 ° C., specific gravity of 1.9 ± 0.1, and particle size It is recommended to use a product of 3.2 ± 1Φ. The reinforcing agent is preferably used 5 to 7% by weight, when the content of the reinforcing agent is less than 5% by weight it may be difficult to increase the strength of the polyethylene, when the content of more than 7% by weight may weaken the strength of the polypropylene.
본 발명에서 상기 결합제는 섬유질과 열가소성수지의 결합을 도울 뿐만 아니라, 성형 시 고열에 혼합조성물이 타지 않도록 한다. 상기 결합제는 폴리프로필렌을 포함할 수 있으며, 열가소성수지에 포함된 폴리프로필렌과 구별된 조성물로서, 바람직하게는 말레이트를 처리한 폴리프로필렌(maleated poly-propylene; MAPP) 1~3 중량%를 사용할 수 있으며, 보다 바람직하게는 폴리프로필렌 95±3.8 중량%, 무스말레인산 1.2 중량% 이상을 포함하여 이루어진 조성물을 사용할 수 있다.In the present invention, the binder not only helps the fiber and the thermoplastic resin to be bonded, but also prevents the mixed composition from burning at high temperatures during molding. The binder may include polypropylene, and as a composition distinguished from polypropylene included in the thermoplastic resin, preferably, 1-3 wt% of maleated poly-propylene (MAPP) may be used. And, more preferably, a composition comprising 95 ± 3.8% by weight of polypropylene, 1.2% by weight or more of maleic acid may be used.
본 발명에서 상기 윤활제는 섬유질과 열가소성수지, 보강제, 결합제 및 착색제의 흐름성을 도울 뿐만 아니라, 성형 시 마찰력을 최대한 낮추어서 전체의 흐름성을 좋게 하고 섬유질 플라스틱 복합재 제품의 외관을 개선한다. In the present invention, the lubricant not only helps the flowability of the fiber and the thermoplastic resin, the reinforcing agent, the binder and the colorant, but also lowers the friction force as much as possible to improve the overall flowability and improve the appearance of the fibrous plastic composite product.
상기 윤활제는 1~3 중량%를 사용하며 함량이 1 중량% 미만인 경우에는 섬유질과 열가소성수지 간의 분산 및 혼합이 잘 되지 않을 뿐 아니라, 흐름성이 매우 낮아 제품을 제대로 성형하기 어려울 수 있는 반면, 3 중량% 초과일 경우에는 윤활제의 역할을 하지 못하여, 흐름이 한쪽으로만 치우쳐서 성형 시 성형제품의 가장자리가 터져 나가는 현상이 발생 할 수 있다.When the lubricant uses 1 to 3% by weight and the content is less than 1% by weight, not only the dispersion and mixing between the fiber and the thermoplastic resin is poor, but the flowability is very low, so that it may be difficult to mold the product properly. If the weight percentage is exceeded, the lubricant may not play a role, and the flow may be biased to one side, so that the edge of the molded product may burst during molding.
본 발명에서 상기 항균제는 내곰팡이성, 방염, 방충효과를 부여하여 섬유질 플라스틱 복합재의 수명을 연장 시키는 역할을 한다. The antimicrobial agent in the present invention serves to extend the life of the fibrous plastic composite by imparting mildew resistance, flame retardant, insect repellent effect.

본 발명의 섬유질 플라스틱 복합재를 제조하는 방법은 섬유질을 20~80 메쉬(mesh)로 분쇄한 후 건조하는 단계, 상기 건조시킨 섬유질에 열가소성수지, 보강제, 결합제를 혼합하는 단계, 상기 혼합물에 윤활제와 항균제를 혼합하는 단계 및 상기 혼합조성물을 100~230 ℃의 온도 조건하에서 성형하는 단계를 포함한다.Method for producing a fibrous plastic composite of the present invention is a step of pulverizing the fiber to 20 to 80 mesh (mesh) and then drying, mixing the dried resin with a thermoplastic resin, a reinforcing agent, a binder, a lubricant and an antimicrobial agent in the mixture Mixing and molding the mixed composition under a temperature condition of 100 ~ 230 ℃.
도 1은 본 발명의 혼합조성물을 이용하여 일실시예에 따라 섬유질 플라스틱 복합재를 제조하는 방법을 나타낸 흐름도이다.1 is a flow chart showing a method for producing a fibrous plastic composite according to one embodiment using the mixed composition of the present invention.
도 1을 참조하면, 섬유질 플라스틱 복합재를 제조하는 방법은 크게 혼합조성물을 제조하는 단계(S110, S120, S130, S140)와 혼합된 조성물에 압력을 가하여 일정한 형태의 섬유질 플라스틱 복합재로 성형시키는 단계(S150)를 거친다.Referring to FIG. 1, a method of manufacturing a fibrous plastic composite may include forming a fibrous plastic composite having a predetermined shape by applying pressure to the composition mixed with the steps S110, S120, S130, and S140. Go through).
먼저, 혼합조성물 제조단계는 섬유질을 20~80 메쉬로 분쇄한 후 수분함량이 2 중량% 이하가 되도록 건조하는 제1단계(S110), 열가소성수지 24~32 중량%, 보강제 5~7 중량%, 결합제 1~3 중량%를 계량 및 혼합하는 제2단계(S120), 제1단계(S110)에서 건조된 섬유질 52~64 중량%와 제2단계(S120)의 혼합물에 윤활제 1~3 중량%를 혼합하는 제3단계(S130), 제3단계(S130)의 혼합물에 항균제 0.1~1 중량%를 혼합하는 4단계(S140)를 포함한다. First, the mixed composition manufacturing step is the first step (S110) for drying the fiber content to pulverized to 20 to 80 mesh to less than 2% by weight, thermoplastic resin 24 ~ 32% by weight, reinforcing agent 5 ~ 7% by weight, In the second step (S120) of measuring and mixing the binder 1 to 3% by weight, a lubricant 1 to 3% by weight of the mixture of 52 to 64% by weight of the fiber dried in the first step (S110) and the second step (S120) The third step (S130) of mixing, the fourth step (S140) of mixing 0.1 to 1% by weight of the antimicrobial agent in the mixture of the third step (S130).
이때, 제1단계(S110)에서 섬유질을 20~80 메쉬로 분쇄한 후 수분함량이 2 중량%이하가 되도록 건조시키는 이유는 폭발성을 없애기 위해서이다. 섬유질은 수분이 많으면 고열(100~230℃)에서 폭발이 일어나므로 3대의 건조기를 이용하여 1차, 2차, 3차에 걸쳐 단계적으로 수분을 낮춰, 수분 함량이 최소한 2 중량% 이하가 되도록 하여 폭발성을 제거할 수 있다.At this time, the first step (S110) after grinding the fiber to 20 to 80 mesh, the reason for drying so that the moisture content is less than 2% by weight in order to eliminate the explosive. If the fiber has a lot of moisture, it explodes at high temperature (100 ~ 230 ℃), so the moisture is lowered in steps of 1st, 2nd, and 3rd steps with 3 dryers, so that the moisture content is at least 2% by weight. Can explode
이렇게 형성된 혼합조성물은 100~230℃ 온도조건 하에서 섬유질 플라스틱 복합재를 성형하는 제5단계(S150)를 거친다. 이때, 성형방법은 당해 분야에서 일반적으로 사용하는 것으로서 압출성형, 사출성형, 프레스성형 등이 있으나, 이에 한정되지 않는다. 바람직하게는 혼합조성물을 녹여서 성형해야 하므로 100~230℃ 온도에서 진행되어야 한다. 일례로 압출성형을 하는 경우에는 100~230℃ 온도에서 혼합조성물을 밀가루 반죽과 같은 형태로 녹인 후 120~140 kg/cm2의 압력을 가함으로써 성형한다.The mixed composition thus formed is subjected to a fifth step (S150) of molding the fibrous plastic composite under a temperature condition of 100 ~ 230 ℃. At this time, the molding method is generally used in the art, but extrusion molding, injection molding, press molding and the like, but is not limited thereto. Preferably it must proceed at a temperature of 100 ~ 230 ℃ because it must be melted to form a mixed composition. For example, in the case of extrusion molding, the mixed composition is melted at a temperature of 100 ° C. to 230 ° C., and then molded by applying a pressure of 120 ° C. to 140 kg / cm 2 .
이때, 성형단계를 거쳐 제조된 펠릿은 제조하는 섬유질 플라스틱 복합재 1회 성형에 필요한 하나의 정량화된 단위체를 혼합조성물을 사용하여 미리 성형한 것이다. At this time, the pellets prepared through the molding step are pre-molded one quantified unit required for one-time molding of the fibrous plastic composite to be manufactured using the mixed composition.
또한, 섬유질 플라스틱 복합재에 색깔을 입히기 위하여 상기 제4단계에서 착색제 3~5 중량%를 더 혼합하여 제조할 수 있다.
In addition, in order to color the fibrous plastic composite, it may be prepared by further mixing 3 to 5% by weight of the colorant in the fourth step.
