이하, 본 발명의 가장 바람직한 일 실시예의 구성을 보다 상세히 설명한다.
Hereinafter, the configuration of the most preferred embodiment of the present invention will be described in detail.
본 발명은 탄화된 목재 숯을 350±50 매쉬로 미세하게 분쇄한 후 이를 건조실에서 약 60℃로 4~6시간 동안 건조하여 수분을 제거한다.The present invention is finely pulverized carbonized wood char with 350 ± 50 mesh and then dried in a drying chamber at about 60 ℃ for 4-6 hours to remove moisture.
그리고, 본 발명에 따른 분말 형태의 숯 25 ~ 35 중량부을 준비하고, 실란트(sealant) 4 ~ 7 중량부 및 첨가제 2 ~ 4 중량부 및 규산칼륨(K₂SiO₃)과 규산나트륨(Na₂SiO₃) 혼합물 1 ~ 2 중량부를 교반기에 넣고 약 40여분간 혼합하여 반죽하여 숯 반죽물을 만든다. 첨가제는 습윤제, 증점제, 암모니아, 알코올, 목초액의 혼합으로 이루어진다.Then, 25 to 35 parts by weight of powdered charcoal according to the present invention is prepared, and 4 to 7 parts by weight of a sealant and 2 to 4 parts by weight of an additive and a mixture of potassium silicate (K₂SiO₃) and sodium silicate (Na₂SiO₃) 1 to 2 Add the weight part to a stirrer and mix for about 40 minutes to make a charcoal dough. The additive consists of a mixture of humectant, thickener, ammonia, alcohol, wood vinegar.
숯은 주지된 바와 같이, 탄소와 미네랄이 주성분인 다공체로서 생물체의 산화를 막아주어 부패 미생물의 서식 환경을 정화하고, 환원작용에 의해 주변 물질의 신선도를 높여 주는 역할을 한다. 또한, 물을 정수하고, 음이온을 발생시켜 공기를 정화하며, 냄새의 원인이 되는 양전자를 흡수하여 탈취하며, 독성물질을 제거하는 작용을 한다.Charcoal, as is well known, is a porous body composed mainly of carbon and minerals, which prevents oxidation of living organisms, purifies the habitat environment of decaying microorganisms, and plays a role of enhancing the freshness of surrounding materials by reducing. In addition, it purifies water, generates anions, purifies the air, absorbs and deodorizes positrons that cause odors, and removes toxic substances.
상기와 같이 반죽된 숯 반죽물에 열가소성 폴리우레탄(TPU) 또는 폴리유산(PLA) 65 중량부를 혼합한다.65 parts by weight of thermoplastic polyurethane (TPU) or polylactic acid (PLA) is mixed with the kneaded charcoal dough.
열가소성 폴리우레탄(TPU)은 다른 수지보다 저온특성이 우수하고, 유연성이 풍부하며, 내구성, 내마모성이 양호하며, 인장강도, 신장율, 내피로성 등의 기계적 성질이 뛰어나며, 내굴곡성, 내한성 및 내유성이 우수하여 광범위한 분야에 사용되고 있다.Thermoplastic Polyurethane (TPU) has better low temperature characteristics than other resins, is rich in flexibility, has good durability and wear resistance, and has excellent mechanical properties such as tensile strength, elongation and fatigue resistance, and excellent bending resistance, cold resistance and oil resistance. It is used in a wide range of fields.
특히, 열가소성 폴리우레탄(TPU)은 상온에서 물성의 큰 변화없이 물속에서 사용이 가능하지만, 대략 80℃ 이상의 온수에서는 에스테르기가 가수분해되므로, 폴리에스테르계 폴리우레탄은 물성이 크게 변하게 된다. 그러나 폴리에테르계 폴리우레탄은 온수에서 물성의 변화가 없기 때문에, 빈번하게 온수와 접촉하게 되는 폴리우레탄 항균 도마의 재료로서 적합하다.In particular, thermoplastic polyurethane (TPU) can be used in water without significant change in physical properties at room temperature, but since the ester group is hydrolyzed in hot water of about 80 ° C. or more, the polyester-based polyurethane has a large change in physical properties. However, since the polyether-based polyurethane has no change in physical properties in hot water, it is suitable as a material for polyurethane antibacterial cutting board which is frequently in contact with hot water.
따라서, 숯이 함유된 도마에 본 열가소성 폴리우레탄(TPU)이 혼합되어 성형됨으로 인해 탄성이 있으면서도 내마모성이 우수하고, 칼날에 의해 도마에 홈이 형성되거나 음식재료가 밀려나지 않는 장점이 있다.Therefore, the present thermoplastic polyurethane (TPU) is mixed and molded on a cutting board containing charcoal, thereby having excellent elasticity and abrasion resistance, and having a groove formed on the cutting board by a blade or a food material being not pushed out.
또한, 폴리유산(PLA)은 옥수수에서 추출한 식물성 원료로 생분해성 물질로서, 의료용 봉합사나 식기 등에 많이 사용하고 있다. 특히 천연소재이므로 환경호르몬의 유발염려가 없어 인체에 무해하며 자연분해되는 장점을 가지므로, 본 발명의 도마 또한 친환경적인 도마가 제조된다.In addition, polylactic acid (PLA) is a vegetable raw material extracted from corn and is a biodegradable material, and is widely used for medical sutures and tableware. In particular, since it is a natural material, there is no fear of causing environmental hormones, so it is harmless to the human body and has an advantage of being naturally decomposed.
숯과 열가소성 폴리우레탄(TPU) 또는 폴리유산(PLA)이 혼합된 혼합물에 알루미나(Al₂O₃) 2 중량부, 산화지르코늄(ZrO₂)과 산화칼슘(CaO)의 혼합물 2 중량부가 혼합된다.2 parts by weight of alumina (Al₂O₃) and 2 parts by weight of a mixture of zirconium oxide (ZrO₂) and calcium oxide (CaO) are mixed in a mixture of charcoal and thermoplastic polyurethane (TPU) or polylactic acid (PLA).
즉, 알루미나(Al₂O₃)는 도마의 내마모성, 전기절연성을 우수하게 유지시켜 주고, 유해 성분을 흡착시켜 주게 된다. 산화칼슘(CaO)은 강중 알루미나의 유해성을 저감하게 된다.That is, alumina (Al₂O₃) maintains excellent wear resistance and electrical insulation of the cutting board and adsorbs harmful components. Calcium oxide (CaO) reduces the harmfulness of alumina in the steel.
또한, 산화지르코늄(ZrO₂)에 의해 유,무기산, 강알카리등에 매우 뛰어난 내식성을 보이고, 화학 공정에서 장치의 수명을 높이고 유지할 수 있게 된다. In addition, the zirconium oxide (ZrO₂) shows very excellent corrosion resistance to organic, inorganic acids, strong alkali, etc., it is possible to increase and maintain the life of the device in the chemical process.
아울러, 본 발명의 도마는 PP-MgO 2 ~ 3 중량부, 이산화규소(SiO₂) 2 중량부, 이산화티타늄(TiO₂) 2 중량부를 혼합하여 구성할 수도 있다.In addition, the cutting board of the present invention may be configured by mixing 3 parts by weight of PP-MgO, 2 parts by weight of silicon dioxide (SiO₂), and 2 parts by weight of titanium dioxide (TiO₂).
PP-MgO는 고무플라스틱 등의 가황 촉진제, 안정제와 폴리에스터 컴파운드의 점도절제로 사용 및 제산제 및 하제로 사용되고, 이산화규소(SiO₂), 이산화티타늄(TiO₂)은 도마성형 사용 시 높은 살균력과 항균력을 유지시켜 준다.PP-MgO is used as a vulcanization accelerator, stabilizer and polyester compound, and as an antacid and laxative for rubber plastics, and silicon dioxide (SiO₂) and titanium dioxide (TiO₂) maintain high sterilization and antibacterial properties when using cutting boards. Let it be.
이렇게 혼합된 마스터배치는 사출시 수지의 흐름 방향으로 가스가 퍼져 나가므로, 성형품을 취출해 보면 보통 수지의 흐름 방향으로 실버 스트리크 현상이 나탄게된다.In this way, the mixed masterbatch spreads the gas in the direction of resin flow during injection, so when a molded article is taken out, silver streaks usually appear in the direction of resin flow.
따라서, 숯을 함유하고 있는 마스터배치는 수분 및 습기를 함유하고 있으므로, 사출 성형시 수분 및 습도조절을 하여 불량율을 줄이기 위해 건조기에 80℃의 온도에서 약 2~4시간 동안 충분히 수분을 건조시킨다.Therefore, the master batch containing charcoal contains moisture and moisture, so that moisture and humidity are controlled during injection molding to dry the moisture sufficiently for about 2 to 4 hours at a temperature of 80 ° C. in a dryer to reduce the defect rate.
그리고, 건조된 마스터배치를 약 180 ~ 200℃의 온도로 되는 사출기에 넣어 보합성형한다. 이때, 사출성형압력은 500 ~ 1,500kg/㎢으로 조정하며 금형온도는 50 ~ 70℃에 맞춘다.Then, the dried masterbatch is put into an injection molding machine having a temperature of about 180 to 200 ° C., and then molded. At this time, the injection molding pressure is adjusted to 500 ~ 1500kg / ㎢ and the mold temperature is set to 50 ~ 70 ℃.
사출성형된 도마는 두께를 2 ~ 4mm로 제작하며, 제작된 도마는 표면마무리작업을 하여 제품을 완성한다.Injection molded cutting board is 2 ~ 4mm thick, and finished cutting board finishes the product.
따라서, 본 발명의 플라스틱 조성물에 의해 성형된 제품은 실란트에 의해 접착성이 향상되고 건조후에도 점착성이 견고하게 되며, 규산칼륨(K₂SiO₃)과 규산나트륨(Na₂SiO₃) 혼합물에 의해 내충격성이 향상되게 된다.Therefore, the product molded by the plastic composition of the present invention is improved adhesiveness by the sealant, the adhesiveness is strong even after drying, and impact resistance is improved by the mixture of potassium silicate (K₂SiO₃) and sodium silicate (Na₂SiO₃).
이때, 첨가제는 습윤제, 증점제, 암모니아, 알코올, 목초액이 소량씩 혼합되어 이루어진다. 즉, 목초액은 초산으로서 살균작용을 하며, 알코올은 배합 후 건조시 빠른 증발을 유도하며, 암모니아는 접착성을 높혀주는 보조 첨가제 역할을 한다.At this time, the additive is made by mixing a small amount of the humectant, thickener, ammonia, alcohol, wood vinegar. In other words, wood vinegar is a sterilization action as acetic acid, alcohol induces rapid evaporation when drying after mixing, and ammonia serves as an auxiliary additive to increase the adhesion.
그리고, 본 발명의 다른 일 실시예로 친환경 플라스틱 조성물 100중량부에 구아검(Guar gum) 3중량부를 혼합하고, 여기에 폴리비닐알콜(PVA) 2중량부 또는 섬유소풀(CMC) 2중량부를 더 혼합하는 것도 바람직하다. In another embodiment, 3 parts by weight of guar gum is mixed with 100 parts by weight of an environmentally friendly plastic composition, and 2 parts by weight of polyvinyl alcohol (PVA) or 2 parts by weight of fibrin glue (CMC) is added thereto. It is also preferable to mix.
천연식품인 구아검(Guar Gum)은 대량의 물을 흡수하여 점도가 높은 분산액을 만드는 작용이 있는 것으로서, 예로부터 완화제로 사용해왔다.Guar gum, a natural food, has the effect of absorbing large amounts of water to create a highly viscous dispersion, and has been used as an emollient since ancient times.
따라서, 숯이 함유된 플라스틱 조성물에 의해 제조된 제품은 견고하면서도 탄성과 유연성이 우수하고, 온도에 의해 물성의 영향을 크게 받지 않게 된다.
Therefore, the product produced by the plastic composition containing charcoal is durable, but excellent in elasticity and flexibility, and is not significantly affected by physical properties by temperature.
