그리고, 상기 생분해성 수지는, 폴리부틸렌 아디페이트 테레프탈레이트(Polybutylene adipate terephthalate; PBAT)와, 폴리락트산(Polylactic acid; PLA)을 포함하는 것이다.In addition, the biodegradable resin includes polybutylene adipate terephthalate (PBAT) and polylactic acid (PLA).
여러 생분해성 소재 중에서도 PBAT는 화석연료 기반의 생분해성 플라스틱으로 자연에서 빠르게 분해되며 유연성과 가공성이 뛰어나다. 이러한 특징으로 농업용 멀칭 필름, 일회용 봉투, 쇼핑백 등에 주로 사용되며 다른 생분해성 플라스틱과의 컴파운딩으로 다양한 용도로 쓰인다. Among various biodegradable materials, PBAT is a fossil fuel-based biodegradable plastic that decomposes quickly in nature and has excellent flexibility and processability. Due to these characteristics, it is mainly used in agricultural mulching films, disposable bags, and shopping bags, and is used for various purposes by compounding with other biodegradable plastics.
생분해성 플라스틱은 탄소 배출량을 최소화하고 생분해됨으로써 시장에서 주목을 받고 있지만, 폭넓은 이용을 위해선 연구가 더욱 필요하다. Biodegradable plastics are attracting attention in the market because they minimize carbon emissions and are biodegradable, but more research is needed for widespread use.
PLA(Poly Lactic Acid)는 옥수수의 전분에서 추출한 원료로 만든 친환경 수지이다. 뜨거운 음식을 담거나, 아기가 입으로 물거나 빨아도 환경호르몬은 물론, 중금속 등 유해 물질이 검출되지 않아 안전하다. 사용 중에는 일반 플라스틱과 동등한 특징을 가지지만 폐기 시 미생물에 의해 100% 생분해되는 재질이다.PLA (Poly Lactic Acid) is an eco-friendly resin made from raw materials extracted from corn starch. It is safe because no harmful substances such as environmental hormones or heavy metals are detected even when hot food is put in it or a baby bites or sucks it. It has the same characteristics as regular plastic during use, but is 100% biodegradable by microorganisms when discarded.
친환경 소재에 대한 기업과 소비자의 관심이 높아지면서 인도 및 북아프리카에서 한해 풀로 알려진 양마(Kenaf)에 대한 관심 증대되고 있다.As interest from companies and consumers in eco-friendly materials increases, interest in Kenaf, known as annual grass in India and North Africa, is increasing.
특히 도요타 자동차계열 시트메이커인 아라코 등에서는 자동차 문 내장재로 양마(Kenaf)를 사용하고 있으며, 양마가 기존 플라스틱에 비해 내열성이나 내충격성이 손색이 없어 그냥 버려진 잡초였던 양마(Kenaf)에 대한 수요가 급증 추세에 있다.In particular, Araco, a seat manufacturer affiliated with Toyota, is using kenaf as an interior material for car doors, and since kenaf has better heat resistance and impact resistance than existing plastics, the demand for kenaf, which was once a discarded weed, is rapidly increasing. There is a trend.
한편, 본 발명에서 양마(kenaf)가공 소재는, 양마 속대(1) 가공 파우더와 양마 껍질(2) 가공 소재를 포함하는 것이다.Meanwhile, in the present invention, the kenaf processing material includes kenaf processing powder and kenaf cob (1) processing material.
도 3에 도시된 바와 같이, 양마의 줄기 수평 단면에서, 양마 줄기는 껍질(2)과, 껍질 안쪽을 구성하는 속대(1)로 구성된다. 양마 줄기를 수평으로 절단하면 옥수수 줄기 내부와 유사하게, 껍질(2)과 하얀색의 부드러운 속대(1)로 이루어진다.As shown in Figure 3, in the horizontal cross section of the stem of the yam, the stem of the yam is composed of the bark (2) and the cob (1) that constitutes the inside of the bark. When the hemp stalk is cut horizontally, it consists of a husk (2) and a white, soft cob (1), similar to the inside of a corn stalk.
속대(1)는 가벼운 물질로 이루워져 있고, 양마 속대(1)는 파우더는 80메쉬~400메쉬를 통과할 수 있도록 아주 잘게 분말 형태로 가공된다.The cob (1) is made of a light material, and the horse cob (1) is processed into very fine powder form so that the powder can pass through 80 mesh to 400 mesh.
상기와 같이 속대(1)를 분말 형태로 아주 잘게 가공된 가루를 속대 가공 파우더라고 한다. As described above, the powder in which the cob (1) is very finely processed into powder form is called cob processed powder.
상기 양마 속대 가공 파우더는 매우 가벼운 물질로 비중이 0.3이다. 상기와 같이 비중이 0.3인 양마 속대 가공 파우더를 생활용품 제조 소재로 혼합되므로, 가벼운 생활용품 제조가 가능하게 된다. The horse cob processed powder is a very light material and has a specific gravity of 0.3. As described above, the processed horse cob powder with a specific gravity of 0.3 is mixed as a material for manufacturing household goods, making it possible to manufacture light household goods.
한편, 양마(kenaf) 껍질(2) 가공소재는 육면체로 가공하되,Meanwhile, the kenaf bark (2) processing material is processed into a hexahedron,
상기 육면체의 가로길이(w)는 1mm ~ 3mm로 가공되고, 세로길이(b)도 1mm ~ 3mm로 가공되며, 육면체의 높이(h)는 0.1 ~ 0.3mm인 것을 특징으로 한다.The horizontal length (w) of the hexahedron is processed to be 1 mm to 3 mm, the vertical length (b) is also processed to be 1 mm to 3 mm, and the height (h) of the hexahedron is 0.1 to 0.3 mm.
상기 양마 껍질 가공소재는 친환경 컴파운드의 구성하는 생분해성 수지간의 가교 역할을 하여, 친환경 컴파운드의 강도를 증가시키는 것이 주목적이다.The main purpose of the horse bark processing material is to increase the strength of the eco-friendly compound by acting as a bridge between the biodegradable resins that make up the eco-friendly compound.
그리고, 양마 껍질 가공소재는, 상기 친환경 컴파운드를 구성하는 양마 속대 가공 파우더, 첨가제, 생분해성 수지들간의 결합력을 증대시키는 역할도 한다.In addition, the hemp bark processing material also serves to increase the bonding strength between the hemp cob processing powder, additives, and biodegradable resins that make up the eco-friendly compound.
그리고, 양마 속대(1)를 분말 형태로 아주 잘게 갈아서 만든 가루를 양마 속대 가공 파우더라고 하는데, 양마 속대 가공 파우더는 가벼워서 생활용품을 경량으로 제조 가능하게 한다.In addition, the powder made by grinding the horse cobs (1) very finely into powder form is called horse cob processing powder, and the horse cob processing powder is light, making it possible to manufacture household goods in a lightweight manner.
또한, 양마 속대 가공 파우더는 생분해성 수지에 비해 가격이 매우 저렴하여 생활용품을 저렴하게 양산 생산 가능하게 한다.In addition, the powder processed from horse cobs is very inexpensive compared to biodegradable resin, making it possible to mass-produce household goods at low cost.
이와 더불어, 양마 속대 가공 파우더는 열전도율이 낮아서, 생활용품에 뜨거운 것을 담아도 생활용품이 고온으로 가열되지 않으므로, 생활용품 소재로서 적합하다.In addition, the powder processed from horse cobs has a low thermal conductivity, so even if hot items are placed in household goods, the household goods are not heated to high temperatures, making it suitable as a material for household goods.
또한, 양마 속대 가공 파우더는, 양마 껍질 가공소재와 함께 생분해성 수지간의 결합성을 증대시키는 효과도 있다.In addition, the horse cob processing powder has the effect of increasing the bonding between the horse horse bark processing material and the biodegradable resin.
이와 같이 본 발명은 생분해성 수지에 비해 가격이 매우 저렴한, 양마 줄기의 속대와 껍질을 모두 이용하여 생활용품을 저렴하게 양산 생산 가능하게 한다.As such, the present invention makes it possible to mass-produce household goods inexpensively by using both the cob and the skin of the hemp stem, which are very inexpensive compared to biodegradable resin.
한편, 본 발명의 생활용품 제조 원료로 사용되는 친환경 컴파운드는, 폴리부틸렌 아디페이트 테레프탈레이트 (Polybutylene adipate terephthalate; PBAT)가 23~30중량%이고, 폴리락트산(Polylactic acid; PLA)이 37~50중량%이며, 양마(kenaf) 속대(1) 가공 파우더가 10~29중량%이고, 양마(kenaf) 껍질(2) 가공소재가 9~20중량%이며, 첨가제가 1~2중량% 포함되는 것을 특징으로 하는 생활용품제조 원료용 생분해성 친환경 컴파운드이다.Meanwhile, the eco-friendly compound used as a raw material for manufacturing household goods of the present invention contains 23 to 30% by weight of polybutylene adipate terephthalate (PBAT) and 37 to 50% by weight of polylactic acid (PLA). It is a percentage by weight, and contains 10 to 29% by weight of kenaf cob (1) processed powder, 9 to 20% by weight of kenaf bark (2) processed material, and 1 to 2% by weight of additives. It is a biodegradable, eco-friendly compound used as a raw material for manufacturing household goods.
생분해성 수지인 PBAT와 PLA는 가격이 양마 가공 소재보다 매우 고가이므로, 본 발명에서는 PBAT와 PLA와 최대한 최소로 혼합되고, 양마 가공 소재를 최대한 많이 혼합하여, 생분해성 생활용품 제조 원료용 친환경 컴파운드를 만든다.Since PBAT and PLA, which are biodegradable resins, are much more expensive than raw hemp processing materials, in the present invention, PBAT and PLA are mixed as minimally as possible and the raised hemp processing materials are mixed as much as possible to create an eco-friendly compound for use as a raw material for manufacturing biodegradable household goods. make it
그러나, 양마 가공 소재를 너무 많이 혼합되면, 생활용품의 강도가 너무 약화되고, 생활용품 세척시 생활용품의 물리적 특성이 변화되어 생활용품으로서 기능을 달성할 수 없다. However, if too much of the hemp processing material is mixed, the strength of the household goods is weakened too much, and the physical properties of the household goods change when the household goods are washed, making it impossible to function as a household goods.
본 발명인은 수많은 시행착오와 연구를 거듭하여, 생활용품으로서 물리적·화학적 특성을 유지 가능하면서, 저렴하게 생활용품을 생산할 수 있는 생분해성 생활용품제조 원료용 친환경 컴파운드의 조성비율은 상기와 같다는 것을 발명하였다.Through numerous trials and errors and research, the present inventor has discovered that the composition ratio of an eco-friendly compound for manufacturing biodegradable household goods that can produce household goods at low cost while maintaining the physical and chemical properties as household goods is as described above. did.
