Description
본 발명은 선도유지 및 항균력을 갖는 합성수지재의 제조방법에 관한 것으로, 보다 상세하게는 생체효과가 있고, 물분자 활성화가 이루어지며, 악취제거와 생육촉진, 신선도유지 및 항균효과 등이 있는 합성수지재의 제조방법에 관한 것이다.The present invention relates to a method for producing a synthetic resin material having a freshness and antimicrobial activity, and more specifically, has a biological effect, activation of water molecules, odor removal and growth, production of synthetic resin materials with freshness and antibacterial effect It is about a method.
플라스틱 제품은 사상균에 의해 가소제가 분해되어 열화되는 것으로 알려져 있다. 예를 들어, 폴리염화비닐의 염화에 대해서 실험하여 가소제의 75∼88%가 세균(Pseudomosnas aerug1nosa)과 사상균(Aspergillus niger, penlcillum funiculosume, Paecilomyees variorti, Trichoderma virlde, Chaetomium globosum)에 의해 분해된다고 알려져 있다.Plastic products are known to deteriorate by degrading plasticizers by filamentous fungi. For example, 75-88% of plasticizers are known to be degraded by bacteria (Pseudomosnas aerug1nosa) and filamentous fungi (Aspergillus niger, penlcillum funiculosume, Paecilomyees variorti, Trichoderma virlde, Chaetomium globosum).
그리고, 포장용 플라스틱 필름일 경우에는 Penlcillium chryosgenum이 생육하지만 폴리염화비닐리덴, 폴리스틸렌에는 생육하지 않는다. 그러나 Aspergillus niger는 폴리염화비닐, 폴리염화비닐리덴, 폴리스틸렌 모두에 있어서 잘 생육한다고 알려져 있다.In the case of the packaging plastic film, Penlcillium chryosgenum grows but does not grow on polyvinylidene chloride and polystyrene. However, Aspergillus niger is known to grow well in polyvinyl chloride, polyvinylidene chloride, and polystyrene.
열대의 기후조건하에서는 폴리염화비닐이 사상균에 의해 5∼6주 정도면 70% 이상 분해된다는 보고도 있다. 사상균은 색소 형성능력도 가지고 있기 때문에 플라스틱 제품의 상품가치를 떨어뜨리는 원인이 된다.Under tropical climatic conditions, polyvinyl chloride is reported to decompose more than 70% by 5 to 6 weeks by filamentous fungi. Filamentous fungi also have a pigment-forming ability, which reduces the product value of plastic products.
이러한 문제점들은 제품 자체의 품질을 저하시키는 원인이 되었다.These problems caused the quality of the product itself to deteriorate.
그리고 또한 종래의 필름은 폴리에틸렌의 단일 성분으로 제조된 것으로, 표면이 매끄럽지 못하고, 필름을 폴리백으로 할 경우 열접합부위에 접합이 용이하지 않았다.In addition, the conventional film is made of a single component of polyethylene, and the surface is not smooth, and when the film is made of polybag, the film is not easily bonded to the thermal joint.
상기, 폴리백으로 하여 열접합 할 경우 열접합부위의 접합이 용이하지 않음에 따라 액체를 보관할 시 누수현상 등이 발생하는 문제점이 있었다.When the thermal bonding is performed using the poly bag, there is a problem in that leakage occurs when the liquid is stored since the thermal bonding is not easily bonded.
그리고, 기존의 필름은 인장강도가 낮아 쉽게 찢어지고 과일, 야채, 김치, 생선, 육류 및 식품등을 보관할 시 신선도가 떨어지며, 탈취효과, 생육촉진, 악취제거 및 항균효과 등의 효과가 그다지 기대할 수 없는 것이었다.In addition, the existing film is easily torn due to low tensile strength, and freshness is reduced when storing fruits, vegetables, kimchi, fish, meat, and foods, and deodorizing effect, growth promotion, odor removal, and antibacterial effect can be expected very much. It was not.
상기, 폴리에틸렌은 이론적으로는 메틸렌 쇄(사슬)의 연속체로 볼 수 있으나 (아래의 폴리에틸렌 분자구조 참조) 다른 종류 구조로서 분기(分岐), 2중결합 카르보닐기 등이 있으며 이 중에서 양적으로 많은 분기의 영향이 가장 크다. 예컨대 폴리에틸렌을 분자 구조의 차이에서 구별하는 경우 중저압법 폴리에틸렌을 직쇄상 폴리에틸렌, 고압법 폴리에틸렌을 분기 폴리에틸렌이라고 하는 때가 있는데 이것은 중저압법, 고밀도 폴리에틸렌에는 분기가 거의 없고 에틸렌 단위가 직쇄상으로 연결된 분자구조를 취하는데 대해서 고압법 저밀도 폴리에틸렌에는 주쇄 중에 매어달린 분기가 존재하기 때문이다. 그리고 이 분기는 폴리에틸렌의 결정화를 방해하는 요인으로 작용하고 밀도에 크게 영향을 준다.The polyethylene can theoretically be seen as a continuum of methylene chains (see polyethylene molecular structure below), but there are other types of structures, such as branched and double-bonded carbonyl groups. This is the biggest. For example, when polyethylene is distinguished from differences in molecular structure, the low and low pressure polyethylene is called linear polyethylene, and the high pressure polyethylene is called branched polyethylene. This is because high-pressure low-density polyethylene has hanging branches in the main chain in order to take the structure. This branch acts as a barrier to the crystallization of polyethylene and greatly affects its density.

※ 폴리에틸렌의 분자구조 ※※ Molecular structure of polyethylene ※
폴리에틸렌의 밀도는 결정영역에 있어서 약 1.0, 또한 비결정영역에서는 약 0.8이기 때문에 결정화도가 클수록 전체의 밀도가 커진다.Since the density of polyethylene is about 1.0 in the crystal region and about 0.8 in the amorphous region, the greater the crystallinity, the larger the overall density.
폴리에틸렌의 밀도와 일반적인 성질과의 관계를 표 1에 간단히 나타냈다. 밀도가 변화하면 이와 같이 콜리에틸렌의 기본적인 성질이 변화하기 때문에 폴리에틸렌의 선택에 있어서 중요한 지표가 된다.The relationship between the density of polyethylene and its general properties is shown briefly in Table 1. As the density changes, thus changing the basic properties of the polyethylene, it is an important indicator in the selection of polyethylene.
이상과 같이 폴리에틸렌의 성질은 밀도에 따라 크게 변화하지만 같은 밀도의 것이라도 분자량이 다르면 기계적 성질이나 가공성이 달라진다.As described above, the properties of polyethylene vary greatly depending on the density, but even those of the same density have different mechanical properties and processability when the molecular weight is different.
폴리에틸렌에서는 분자량의 대소를 간접적으로 나타내는 척도로서 일반적으로 멜트인덱스(MI)라는 숫자가 사용되고 있다. 멜트인덱스란 일정한 노즐을 사용, 표준의 온도와 압력하에서 10분간 흐르는 폴리에틸렌의 그램수로 표시된 유동성의 척도이다. 따라서 멜트인덱스가 높은 것은 용융점도가 작으며 흐르기 쉽다는 것이된다. 또한 일반적으로 이 숫자가 작을수륵 재료와 분자량이 크다는 것을 나타내고 있으며 성형품의 기계적 강도는 커지지만 가공성은 나빠진다. 이 멜트인덱스와 일반적인 성질과의 관계를 표 2에 나타냈다.In polyethylene, the number of melt index (MI) is generally used as a measure of indirectly indicating the magnitude of molecular weight. Melt index is a measure of fluidity expressed in grams of polyethylene flowing for 10 minutes under constant temperature and pressure using a constant nozzle. Therefore, the higher the melt index means that the melt viscosity is smaller and easier to flow. In general, the smaller the number, the higher the material and the higher the molecular weight. The higher the mechanical strength of the molded part, the worse the processability. The relationship between this melt index and general properties is shown in Table 2.
또한 폴리에틸렌의 특성은 분자구조(밀도), 분자량(멜트인덱스)외에 분자량 분포의 영향을 받는 것도 잊어서는 안된다.Also, it should not be forgotten that the properties of polyethylene are affected by molecular weight distribution in addition to molecular structure (density) and molecular weight (melt index).
폴리에틸렌 필름은 거의 수분을 통하지 않지만 탄산가스,유기용제, 향료 등의 투과도는 매우 크기 때문에 식료품 기타의 포장재료로서 사용할 때에는 주의를 요한다. 고밀도 폴리에틸렌은 저밀도의 것에 비하여 투습도나 가스투과도는 매우 작다(표 3). 염화비닐리덴 아크릴로 니트릴 공중합체를 도포한다든지 셀로판이나금속박(箔)과 적층함으로써 유기용제나 향료의 투과성을 매우 작게할 수가 있다.Although polyethylene film hardly penetrates water, the permeability of carbon dioxide, organic solvents, fragrances, etc. is very high, so care must be taken when using it as a foodstuff or other packaging material. High density polyethylene has a very small moisture permeability and gas permeability compared to low density (Table 3). By applying a vinylidene chloride acrylonitrile copolymer or laminating with cellophane or metal foil, the permeability of the organic solvent and the fragrance can be made very small.
또한 최근 발전한 다층 압출성형의 기술에 의하여 통기성이 작은 다른 3 플라스틱과 폴리에틸렌을 조합시킨 복합필름으로 만드는 것도 실용화되어 있다.In addition, recent advances in multi-layer extrusion technology have made it possible to produce composite films made of polyethylene and other 3 plastics with low air permeability.
상기와 같은 가스 투과율을 갖는 합성수지 필름을 이용하여 식품을 포장하는 경우 식품으로부터 발생하는 가스의 배출은 어느 정도 가능하나, 그 내부에 서식하는 각종의 균주로 인하여 식품 자체의 신선도는 유지하기 어려운 실정이었다.When the food is packaged using the synthetic resin film having the gas permeability as described above, the gas generated from the food can be discharged to some extent, but the freshness of the food itself is difficult to maintain due to various strains inhabiting therein. .
본 발명자는 상기에서와 같은 기존의 합성수지재에 대한 문제점과 성질등을 감안하여 신선도유지와 항균효과가 있고 생체효과가 있으며 물분자 활성화가 이루어지고 악취제거와 생육촉진등이 이루어지는 신규한 합성수지재 및 그 제조방법을 제공한다.In view of the problems and properties of the existing synthetic resin materials as described above, the present inventors have a fresh synthetic resin material having freshness retention, antibacterial effect, biologic effect, water molecule activation, odor removal and growth promotion, and the like. It provides a manufacturing method.

따라서, 본 발명은 상기와 같은 문제점을 해결하기 위하여 본 발명의 발명자가 발명하여 대한민국 특허청에 선출원한 특허출원 제97-65727호에서 이미 제시하고 있는 산화규소(SiO2) 70.4975중량%, 산화알미늄(Al203) 13.7중량%, 산화철(Fe203) 3.4중량%, 산화마그네슘(MgO) 0.7중량%, 산화칼슘(CaO) 1.6중량%, 산화나트륨(Na2O) 3.5중량%, 산화칼륨(K2O) 2.4중량%, 산화인(P2O2) 0.1중량%, 티타튬(Ti) 0.2중량%, 망간(Mn) 0.2중량%, 세레늄(Se) 0.2중량%, 게르마늄(Ge) 25ppm(0.0025중량%), 은(Ag) 3.5중량%로 구성된 바이오세라믹을 대상수지에 마스터배취(Master batch)시켜 필름 및 사출품등을 제조하여 선도유지 및 항균력을 갖는 합성수지재의 제조방법를 제공하는 것이다.Therefore, the present invention is 70.4975% by weight of silicon oxide (SiO 2 ), which is already proposed in the patent application No. 97-65727, which was invented by the inventor of the present invention and solved the above problems, to the Korean Patent Office. Al 2 0 3 ) 13.7 wt%, iron oxide (Fe 2 0 3 ) 3.4 wt%, magnesium oxide (MgO) 0.7 wt%, calcium oxide (CaO) 1.6 wt%, sodium oxide (Na 2 O) 3.5 wt%, oxidation 2.4 wt% of potassium (K 2 O), 0.1 wt% of phosphorus oxide (P 2 O 2 ), 0.2 wt% of titanium (Ti), 0.2 wt% of manganese (Mn), 0.2 wt% of selenium (Se), germanium (Ge) ) Master batch of bioceramic consisting of 25ppm (0.0025% by weight) and 3.5% by weight of silver (Ag) to the target resin to produce films and injection-molded products to provide a method for producing synthetic resin materials having leading maintenance and antibacterial activity will be.
이상과 같이 구성된 바이오세라믹재에 대한 물리적 성질을 보면 아래와 같다.The physical properties of the bioceramic material constructed as described above are as follows.
이상과 같은 본 발명의 바이오세라믹재를 솔리드상태에서 분말도 300∼475메시로 제조한다.The bioceramic material of the present invention as described above is produced in a solid state of powder 300 to 475 mesh.
상기와 같이 정의된 바이오세라믹재를 하기의 대상수지들에 소정의 범위로첨가하여 마스터배취 시킨다.The bioceramic material defined as described above is added to the following target resins in a predetermined range and then masterbatched.
즉, 폴리에틸렌(PE)에 5∼6중량%, 폴리스티렌(PS)에 8∼10중량%, 아크릴로니트릴부타디엔스틸렌(ABS)에 8∼10중량%, 폴리프로필렌(PP)에 8∼10중량%, 페놀수지에 5∼7중량%, 피브이시(PVC)에 5∼6중량%, 멜라민수지에 4∼6중량% 첨가시켜 마스터배취를 통해 신규한 합성수지재를 제조한다. 이 신규한 합성수지재로 필름, 사출물등 다양한 제품을 제조할 수 있다.That is, 5 to 6% by weight of polyethylene (PE), 8 to 10% by weight of polystyrene (PS), 8 to 10% by weight of acrylonitrile butadiene styrene (ABS), 8 to 10% by weight of polypropylene (PP) 5 to 7% by weight of phenolic resin, 5 to 6% by weight of fibish (PVC) and 4 to 6% by weight of melamine resin are added to prepare a new synthetic resin material through a master batch. This new synthetic resin material can produce a variety of products, such as film, injection molding.
위와 같이 구성된 신규한 합성수지재는 아래와 같은 일반물성을 갖는다.The new synthetic resin material configured as described above has the following general physical properties.
상기 신규한 합성수지재는 강산이나 강알칼리와 접촉시 구조변화가 일어날 수 있으므로 이들 제품과 혼합저장을 피하도록 주의를 요하며 고온 다습한 환경에서는 제품내에 수분이 일부 흡수될 수도 있으므로 장기간 저장시 환기가 잘 되는 곳에 보관해야 한다.The new synthetic resin material may cause structural changes in contact with strong acids or strong alkalis, so care should be taken to avoid mixed storage with these products. In a high temperature and high humidity environment, some of the moisture may be absorbed into the product. It should be kept somewhere.
한편, 수분이 흡습되었을 때 재생방법으로 분말상의 경우 약 300℃, 3시간 이상 건조시켜 사용하고 마스터배취의 경우 90℃ 2시간이상 건조하여 사용하면 불량률을 방지할 수 있다.On the other hand, when the moisture is absorbed by the regeneration method in the case of powdery powder is used to dry for about 300 ℃, 3 hours or more, and in the case of master batch to be used for more than 90 ℃ 2 hours or more can prevent the failure rate.
상기에서의 마스터배취에 대한 실시예로써 첨부된 도면에 따라 아래와 같이설명한다.According to the accompanying drawings as an embodiment for the master batch in the above will be described as follows.
도시된 도 1에서와 같이 0.91∼0.92 정도의 저밀도수지 20∼30중량%, 0.95∼0.96 정도의 고밀도수지 60∼70중량%, 상기에서 정의된 바이오세라믹재 5∼6중량%와종래 널리 합성수지재를 제조하기 위해 첨가되어지는 잔여 공지성분 3∼14.5중량%(여기서 잔여 공지서운이라 함은 유기ㆍ무기안료 등으로써 필름의 색상을 맞추기 위해 당업계에서 널리 사용되어지는 성분을 말하는 것이다.)를 믹싱기(1)에서 약 30분간 믹싱한 후 분산제(Ca-Stearate)를 0.5∼1중량% 첨가하여 브렌딩(Blending)한다.(여기서 바이오세라믹재를 5∼6 중량%를 첨가하는 것은 5중량% 이하로 첨가할 경우 어느 정도의 현저한 효과는 안출되나 실제 필름등의 제품으로 장기간 사용될 경우에는, 그 효과가 약간 미비하다는 문제점이 있어 그 한계를 둔 것이며, 또한 6중량% 이상을 첨가할 경우에는 6중량%와 거의 동일한 효과가 나타나게될 뿐만 아니라 필름등을 제조하는데 있어 생산비용이 크게 증대되어 경제적으로도 비효율적인 문제점이 있은 것이다. 그리고, 고밀도수지 및 저밀도수지를 적량 첨가하는 것은 종래의 필림등 합성수지재를 제조하는데 있어서 널리 사용되고 있는 것이다.) 이후 중간 저장조(2)에서 파이프라인(3)을 경유하여 2차 브렌딩한 후 히팅부(4)에서 180℃∼200℃로 5분∼10분 가열한다. 이어서 커팅수단(5)에 의해 미립자상태로 커팅하고, 쿨링부(6)에서 7∼8℃의 물에 1∼2분간 냉각한 후 드라이부(7)에서 110℃∼120℃로 8분∼10분간 건조하여 포장한다.As shown in FIG. 1, 20 to 30% by weight of the low density resin of about 0.91 to 0.92, 60 to 70% by weight of the high density resin of about 0.95 to 0.96, 5 to 6% by weight of the bioceramic material defined above, and the conventional widely synthetic resin material 3 to 14.5% by weight of the remaining known ingredients added to prepare the (wherein the remaining known ingredients are organic and inorganic pigments, etc., refers to the ingredients widely used in the art to match the color of the film). After mixing for about 30 minutes in the group (1), 0.5-1% by weight of a dispersant (Ca-Stearate) is added and blended (Blowing is performed by adding 5-6% by weight of the bioceramic material). If it is added below a certain remarkable effect is produced, but when used for a long time as a product such as a film, there is a problem that the effect is slightly insignificant, and the limit is placed, and when adding more than 6% by weight 6 With weight percent Not only does the same effect occur, but the production cost is greatly increased in manufacturing films, etc., and there is a problem of economic inefficiency, and adding a proper amount of high density resin and low density resin to produce synthetic resin such as film After the second blending via the pipeline (3) in the intermediate reservoir (2) and then heated in the heating section 4 to 180 ℃ to 200 ℃ 5 minutes to 10 minutes. Subsequently, the cutting means 5 was cut into fine particles, cooled in water of 7 to 8 ° C. for 1 to 2 minutes in the cooling unit 6, and then 8 minutes to 10 ° C. to 110 ° C. to 120 ° C. in the dry unit 7. Dry and pack for a minute.

또, 본 발명의 합성수지재는 신선도유지, 항균력, 생체효과, 물분자활성, 악취제거, 생육촉진등의 효과가 뛰어나다.In addition, the synthetic resin material of the present invention is excellent in maintaining the freshness, antimicrobial activity, biological effect, water molecule activity, odor removal, growth promotion.
그리고, 본 발명의 신규한 합성수지재로서 제조된 필름은 도 2에서와 같이 본 발명의 필름이 일반제품(여기서 일반제품이라 함은 널리 시중에 통용되고 있는 필름으로서 특히 PE필름을 말하는 것이며, 당업계에서는 널리 통용되는 명칭이다.)의 필름보다 우수함을 알 수 있다.In addition, the film produced as a novel synthetic resin material of the present invention, as shown in Figure 2, the film of the present invention is a general product ( where general product refers to a film commonly used in the market, especially PE film, It is known that is a name that is widely used .
특히, 도 2에서 나타나는 바와 같이 일반제품에 야채 등을 담았을 경우에는 3일 정도가 지나면 그 외형변화(여기서 외형변화라 함은 갈변현상 등을 말한다.)가 발생하고, 5일이 경과하면 곰팡이가 발생되며, 6일경에는 부패가 개시되어짐을 잘 알 수 있는 반면, 본 발명에 의한 필름을 사용할 경우에는 거의 15일이 지나서야 신선도의 변화가 일어나기 시작하며, 야채, 빵, 장미 등이 표면이나 잎이 조금씩 건조되기 시작한다는 것을 확인할 수 있는 것이다.In particular, as shown in FIG. 2, when a vegetable is contained in a general product, the appearance change (where the change in appearance refers to browning, etc.) occurs after about 3 days, and after 5 days, mold It can be seen that the corruption is started around 6 days, while using the film according to the present invention, the change in freshness begins to occur after about 15 days, and vegetables, bread, roses and the like surface or leaves You can see that it starts to dry little by little.
상기 본 발명에 의한 필름을 0.91∼0.92 정도의 저밀도 수지에서 상기의 표3에서와 같이 O2(5.5), CO2(25.2), 0.95∼0.96 정도의 고밀도수지에서는 O2(1.06), CO2(3.52) 통기성을 나타내지만 0.91∼0.92 정도의 저밀도, 0.95∼0.96 정도의 고밀도, 상기에서 정의된 바이오세라믹재를 마스터배취하면 분자구조가 장쇄분기구조로 전환하면서 통기성을 적절히 응용할 수 있고, 바이오세라믹재 자체의 제올라이트 구조 특성상 산소를 발생(흡입)하면서 CO2를 배출하여 신선도유지와 항균 및 탈취효과를 얻을 수 있다.In the low density resin of about 0.91 to 0.92, the film according to the present invention is O 2 (5.5), CO 2 (25.2) and O 2 (1.06), CO 2 in high density resin of 0.95 to 0.96 as shown in Table 3 above. (3.52) Although it exhibits breathability, the low density of about 0.91 to 0.92, the high density of about 0.95 to 0.96, and the masterbatch of the bioceramic material defined above enable the application of breathability appropriately while converting the molecular structure into a long-chain branched structure. Due to the zeolite structure of the ash itself, CO 2 can be discharged while generating (suctioning) oxygen to obtain freshness, antibacterial and deodorizing effect.
예를 들어, 야채, 꽃등 잎종류를 사용하는 것은 바이오세라믹재의 첨가량을 약 l∼2% 더한다. 이는 CO2를 배출하고 02공급을 원활하게 해주는 것이 신선도를 유지할 수 있다.For example, using leaf types, such as vegetables and flowers, adds about 1 to 2% of the bioceramic material. This keeps freshness by releasing CO 2 and smoothing the 0 2 supply.
또, 햄, 우유, 두부, 치즈, 뿌리식품은 바이오세라믹재의 첨가량을 2∼3% 줄여야 한다. 이는 CO2를 배출하고 02는 소량만 공급해야하는데 그 이유는 부패의 원인인 습기, 온도, 산소중 02의 차단 효과를 주면 신선도가 유지되고 부패의 원인을 차단할 수 있다.In addition, ham, milk, tofu, cheese, root foods should reduce the amount of bioceramic material added 2-3%. This may be discharged, and 02 is only a small amount to be supplied because the freshness and keeping the main surface the cause of humidity, temperature, and blocked for 02 Effect of the oxygen decay of blocking the cause of the spoilage of CO 2.
