Description

반짝이 합성수지 성형제품의 제조방법 {The manufacture method of the plastic manufacture goods visible the flashing material}The manufacturing method of the plastic manufacture goods visible the flashing material}

본 발명은 반짝이 플라스틱 성형제품의 제조방법에 관한 것으로, 특히 반짝이 물질이 성형제품의 내부에 잔재하여 보존력이 우수하고, 투명도가 높고 반짝이 물질이 선명하게 보여짐으로서 시각 효과를 극대화 할 수 있도록 하기 위한 제품을 제공하기 위한 것이다.The present invention relates to a method for manufacturing a shiny plastic molded product, in particular, a product for maximizing the visual effect by having a shiny material remains in the molded product excellent in the preservation, high transparency and a clear shiny material It is to provide.

종래에 반짝이 효과가 있도록 하기 위하여 제안된 플라스틱 성형제품의 제조방법으로는 완성된 플라스틱 성형물의 외 표면에 젤 코팅(gel coating) 방식으로 접착제를 도포 후 입자상의 반짝이 물질을 재 도포하여 제품의 표면으로 반짝이 물질이 부착토록 함으로서 반짝이 플라스틱 성형물의 제조가 가능토록 한 제조방법이 있으나, 이러한 제조방법은 제품의 품질을 단단하게 하는 결과를 초래하고, 또한 성형제품의 표면에 부착된 반짝이 물질이 외부와의 마찰과 습기에 의하여 쉽게 떨어지게 되는 문제점이 있는 것이다.Conventionally, the method of manufacturing a plastic molded product proposed in order to have a glitter effect is applied to the outer surface of the finished plastic molding by a gel coating method, and then re-coated a particle glitter material to the surface of the product. There is a manufacturing method that enables the production of shiny plastic moldings by adhering the shiny material, but this manufacturing method results in hardening the quality of the product, and also the shiny material adhered to the surface of the molded product is exposed to the outside. There is a problem that easily falls by friction and moisture.

따라서 플라스틱 조성물에 반짝이를 혼합하여 일체로 성형할 수 있으나 이때 통상의 수지가 분자량이 큰 수지와 분자량이 작은 수지를 적절히 혼합하여 사용하기 때문에 여기에 가소제와 안정제 및 색소를 첨가한 상태에서 반짝이 가루를 혼합하여 사용할 경우에 반짝이의 흐름도가 원활하지 않아 성형물의 중앙에 집중되기 때문에 반짝이가 노출되지 않게 됨으로 반짝이 성형물의 제조가 불가능하였던 것이다.Therefore, the plastic composition may be mixed with the glitter to be molded integrally, but since the conventional resin is used by appropriately mixing a resin having a large molecular weight and a resin having a small molecular weight, the glitter powder is added in the state where a plasticizer, a stabilizer, and a pigment are added thereto. When the mixture is used, the flow of glitter is not smooth and is concentrated in the center of the molding, so that the glitter is not exposed, so that the manufacture of the glitter molding was impossible.

따라서 본 발명은 플라스틱용 수지 원료중 분자량이 큰 수지만을 사용하고 여기에 가소제를 수지원료의 최소 50%까지 혼합하여 안정제와 안료 및 반짝이 가루를 혼합하여 사용토록 함으로서 성형시 반짝이 가루의 혼합 흐름도를 빠르게 하고 가소제로 인하여 반짝이가 외부로 나타나게 되면서 반짝이 가루가 성형물의 내부에 잔재된 상태에서 성형되는 제품의 표면으로 선명하게 나타날 수 있도록 한 것이다.Therefore, the present invention uses only a resin having a large molecular weight in the resin material for plastics and the plasticizer is mixed up to at least 50% of the water support material to mix the stabilizer, pigments and glitter powder, so that the mixing flow of the glitter powder during molding It is faster and the plasticizers appear to be sparkling outwards, so that the sparkling powder remains clearly inside the moldings so that they can appear clearly on the surface of the molded product.

<도면의주요부분에대한부호의설명>Explanation of symbols on the main parts of the drawing

도 1은 본 발명에 의한 성형 제조방법을 나타내기 위한 공정도.1 is a process chart for showing a molding manufacturing method according to the present invention.

이하에서는 첨부 도면을 참조하여 본 발명의 가장 바람직한 일 실시 예를 상세히 설명하기로 한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

본 발명의 반짝이 플라스틱 성형제품의 제조방법은 통상적으로 플라스틱용 수지 원료에 가소제와 안정제 및 착색제(안료)로 구성되는 공지의 플라스틱 조성물에 있어서, 사용되는 수지 원료를 분자량이 큰 수지를 사용하고, 액상의 가소제(DINP)를 원료수지 대비 최소 50%로 배합시키고, 여기에 반짝이 가루를 배합시킨 혼합물을 200℃ ∼ 250℃로 성형시켜 제조토록 한 것이다.The production method of the shiny plastic molded article of the present invention is a conventional plastic composition composed of a plasticizer, a stabilizer, and a colorant (pigment) as a resin raw material for plastics. Plasticizer (DINP) of at least 50% compared to the raw material resin, and the mixture of glitter powder mixed therein was molded to be produced at 200 ℃ to 250 ℃.

이때 가소제는 플라스틱 조성물의 물성을 결정하기 위한 첨가제로서, 투입되는 수지 원료 대비 최소한 50% 이상을 배합하여야 투명성이 있게 되고, 이때 가소제의 투입량이 많을수록 성형물의 투명도 및 연성이 우수하게 되는 것이다.In this case, the plasticizer is an additive for determining the physical properties of the plastic composition, and at least 50% or more of the resin material to be added is added to make the transparency, and the more the amount of the plasticizer is added, the better the transparency and the ductility of the molding.

또한 플라스틱용 수지 원료로서는 열가소성수지 또는 열경화성수지의 사용이 가능하고, 고무 원료를 사용하여 상기와 같은 비율로 배합시킨 조성물에도 반짝이 가루를 배합시켜 반짝이 고무 성형제품의 제조도 가능하게 되는 것이다.In addition, thermoplastic resins or thermosetting resins may be used as the resin raw materials for plastics, and glittery powder may also be blended into the composition blended in the above ratio using a rubber raw material to produce a shiny rubber molded product.

이때 상기한 열가소성수지는 ;At this time, the thermoplastic resin;

PVC(Polyvinychloride), PP (Polypropylene), ABS(Acrylonitrile Butadiene Styrene), PMMA(Poly methl meth Acrylate), PE(Polyethylene), PET(Polyethylene Terephthalate), PBT(Polybuthylene Terephthalate), PPS(Polyphenylene Sulfide), PC(Poly cabonate), Nylon, LDPE(Low Density polyethylene), HDPE(High Density polyethylene)이고,Polyvinychloride (PVC), Polypropylene (PP), Acrylonitrile Butadiene Styrene (ABS), Poly methl meth acrylate (PMMA), Polyethylene (PE), Polyethylene Terephthalate (PET), Polybuthylene Terephthalate (PBT), Polyphenylene Sulfide (PPS) Poly cabonate), Nylon, Low Density polyethylene (LDPE), High Density polyethylene (HDPE),

따라서 상기와 같이 원료에 첨가되어지는 가소제를 전량 액상으로 사용하여 원료 조성물의 물성을 변화시킴으로서 배합된 반짝이 가루가 액상의 가소제보다 비중이 작아 혼합물에서의 흐름도가 빨라지기 때문에 성형품의 외측으로 밀려나간 반짝이 가루가 선명하게 나타나게 되는 것이다.Therefore, by using the plasticizer added to the raw material as a whole liquid as described above to change the physical properties of the raw material composition, the mixed powder has a specific gravity smaller than that of the liquid plasticizer, so that the flow in the mixture is faster, and the glitter is pushed out of the molded article. The powder will appear clearly.

또한 가소제로 사용된 DINP의 첨가량이 50% 이상이 되어 투명한 성형품의 제조가 가능하기 때문에 반짝이 효과를 더욱 증진시킬 수 있는 것이다.In addition, since the addition amount of DINP used as a plasticizer is 50% or more, it is possible to further improve the glitter effect because it is possible to manufacture a transparent molded article.

따라서 상기와 같은 제조방법에 의하여 완구류, 문구류, 식기류를 비롯한 모든 생활용품에 적용이 가능한 것이고, 그 외에도 안전성이 뛰어나 유아용품에도 안심하고 적용이 가능한 것이다.Therefore, it is possible to apply to all household goods, including toys, stationery, tableware by the manufacturing method as described above, in addition to the excellent safety it can be applied to the baby products with confidence.

따라서 본 발명의 제조방법에 의하여 제작되어지는 성형제품은 반짝이 물질이 제품의 조성물 내부에 존재하여 외부의 마찰이나 습기에 전혀 영향이 없는 반 영구적 사용이 가능하고, 투명도가 우수하고 반짝이 물질이 제품의 표면으로 선명하게 보여질 수 있기 때문에 제품의 시각적 효과를 극대화 할 수 있는 것이다.Therefore, the molded product manufactured by the manufacturing method of the present invention can be used semi-permanently without any influence of external friction or moisture because the shiny material is present in the composition of the product, the transparency is excellent and the shiny material of the product It can be seen clearly on the surface, which maximizes the visual effect of the product.
