본 발명은 머리핀, 브로우치등과 같은 장신구 및 사진틀과 같은 장식품에 부분적으로 불특정한 진주색상무늬가 연출되도록하는 합성수지를 제조하기 위한 것으로 좀더 상세하게는 두가지 이상의 특정한 합성수지를 강제로 혼합하여 일정한 온도로 가열된 이송실린더를 통과시키면서 강제로 혼합하여 사출하여 성형함으로서 그 성형물에 불특정한 진주색상의 무늬가 부분으로 연출될 수 있도록 한 불특정한 진주색상무늬를 부분적으로 연출하기 위한 합성수지의 제조방법과 이에 의해 제조한 합성수지에 관한 것이다.The present invention is to produce a synthetic resin to produce a non-specific pearl color pattern on ornaments, such as hairpins, broaches, and ornaments, such as a picture frame, more specifically, by heating at a constant temperature by forcibly mixing two or more specific synthetic resins Method of manufacturing synthetic resin to partially produce unspecified pearl-colored patterns in which unspecified pearl-colored patterns can be partly produced by forcibly mixing and injecting and molding through the transfer cylinder It is about a synthetic resin.

일반적으로 머리핀를 포함하는 여러종류의 장신구 및 액자틀과 같은 장식품은 합성수지재로 제조하여 그 취향에 따라 사용하고 있다.Generally, various kinds of ornaments including hairpins and ornaments such as picture frames are manufactured from synthetic resin materials and used according to taste.

이러한 장신구 및 장식품은 그 제조원료가 되는 아크릴로니트릴 부타디엔 스틸렌 수지(A.B.S 수지; Acrylonitrile Butadiene Styrene Resin)와 같은 재질의 합성수지와 사용하는 안료에 의하여 발생하는 따라 고유 색상을 제외하고 그 표면에 각종 무늬를 연출하기 위하여 다양한 방법이 이용되고 있다.These ornaments and ornaments are produced by a synthetic resin of a material such as acrylonitrile butadiene styrene resin (ABS resin), which is a raw material for its manufacture, and various patterns on the surface of the ornament except for intrinsic colors. Various methods are used to produce.

이러한 것은 상기한 바와 같이 그 제조원료가 가지는 고유의 색상이 단조롭기 때문에 종래부터 불특정한 무늬를 연출하기 위해 여러형태로 연구개발되어 오고 있으나 그 원재료 자체에 어떤 불특정의 무늬모양을 연출시키는 것이 불가능하여 각종 스티커를 이용하는 정도에 불과하였다.This is because the inherent color of the raw material is monochromatic as described above, and has been researched and developed in various forms in order to produce an unspecific pattern. However, it is impossible to produce an unspecific pattern on the raw material itself. It was just the use of various stickers.

근래에 들어 상기와 같은 아크릴로니트릴 부타디엔 스틸렌 수지(A.B.S 수지; Acrylonitrile Butadiene Styrene Resin) 또는 아크릴 수지(Acrylate resin)에 진주분말을 첨가하여 혼합함으로서 그 성형품에 불특정한 진주색상을 가진 무늬를 연출하는 방법이 시도되어 고가의 장신구 및 장식품의 원재료로 한정적으로 사용되고 있다.Recently, by adding pearl powder to the above acrylonitrile butadiene styrene resin (ABS resin; Acrylonitrile Butadiene Styrene Resin) or acrylic resin (Acrylate resin) by mixing and producing a pattern having an unspecified pearl color on the molded product It is attempted and is used as a raw material of expensive jewelry and ornaments limitedly.

그러나 상기한 첨가물인 진주분말은 고가이여서 일반적으로 널리 사용될 수없는 문제점이 있다.However, the above-mentioned additives have a problem that pearl powder is expensive and generally cannot be widely used.

본 발명은 상기한 문제점을 근본적으로 해결하기 위하여 창출된 것으로서 종래에 부분적으로 이용하여왔던 불특정한 진주색상의 무늬를 진주분말을 사용하지 않고도 그와 동일하게 연출할 수 있도록하는데 있다.The present invention was created to fundamentally solve the above-mentioned problems, and is intended to produce the same pattern of unspecified pearl color that has been partially used in the past without using pearl powder.

이러한 진주색상 무늬를 연출하기 위해 본 발명에서는 폴리 메틸 메타 크레이트 아크릴 수지(POLY METYL METHACRYLATE ACRYLIC RESIN)와 스티렌 부타디엔 공중합 투명수지(STYRENE BUTADIENE COPOLYMERS CLEAR RESIN)를 혼합하여 이송실린더의 온도 170∼230℃에서 강제로 혼합시키면서 압출하였더니 사출물에서 불특정한 진주색상의 무늬가 부분적으로 연출하였고, 이를 노광에서 시각적으로 관찰하였더니 진주색상의 무늬가 한층 더 또렸하게 연출하고 있음을 확인할 수 있었다.In order to produce such a pearl-colored pattern in the present invention, a polymethyl methacrylate acrylic resin (POLY METYL METHACRYLATE ACRYLIC RESIN) and styrene butadiene copolymerized transparent resin (STYRENE BUTADIENE COPOLYMERS CLEAR RESIN) by mixing the forced cylinder temperature 170 ~ 230 ℃ When the mixture was extruded, the ingot produced a pattern of an indefinite pearl color, and when visually observed this in the exposure, it was confirmed that the pattern of pearl color was more bright.

이하 본 발명을 상세하게 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail.

메타클릭산메틸(Methacrylic acid metyl)이 주성분인 폴리 메틸 메타 크레이트 아크릴 수지(POLY METYL METHACRYLATE ACRYLIC RESIN) 25~75wt%와 스티렌 부타디엔 공중합 투명수지(STYRENE BUTADIENE COPOLYMERS CLEAR RESIN) 75∼25wt%를 혼합한 혼합물을 온도 170∼230℃의 상태를 유지하는 이송실린더에서 강제로 이송시키면서 열에 의해 반죽상태로 겔화시키면서 혼합하여 사출하여 얻은 사출물을 성형하고자하는 형상의 금형에 따라 성형하는데 있다.A mixture of 25 to 75 wt% of polymethyl methacrylate acrylic resin, which is the main component of methacrylic acid metyl, and 75 to 25 wt% of STYRENE BUTADIENE COPOLYMERS CLEAR RESIN The injection molded product obtained by mixing and injecting gelled into a dough state by heat while being forcibly transferred from a transfer cylinder maintaining a temperature of 170 to 230 ° C. is molded according to a mold of a shape to be molded.

이때 상기한 폴리 메틸 메타 크레이트 아크릴 수지(POLY METYL METHACRYLATE ACRYLIC RESIN) 25wt% 이하이면서 스티렌 부타디엔 공중합 투명수지(STYRENE BUTADIENE COPOLYMERS CLEAR RESIN) 75wt% 이상으로 조성하여 혼합하여 사출한 경우에는 진주색상이 아니고 투명의 무늬가 사출물의 전체에 표현되어서 불특정한 무늬를 부분적으로 연출하고자 하는 목적에 반할 뿐만 아니라 그 색상이 투명하여 원하는 진주색상을 연출할 수 없었다.In this case, when the polymethyl methacrylate acrylic resin (POLY METYL METHACRYLATE ACRYLIC RESIN) is 25wt% or less and styrene butadiene copolymerized transparent resin (STYRENE BUTADIENE COPOLYMERS CLEAR RESIN) is formed and mixed and injected, it is not pearl color but transparent. The pattern was expressed throughout the injection molding, not only against the purpose of partially producing the unspecified pattern, but also because the color was transparent, so that the desired pearl color could not be produced.

상기한 폴리 메틸 메타 크레이트 아크릴 수지(POLY METYL METHACRYLATE ACRYLIC RESIN) 75wt% 이상이면서 스티렌 부타디엔 공중합 투명수지(STYRENE BUTADIENE COPOLYMERS CLEAR RESIN) 25wt% 이하로 조성하여 혼합하여 사출한 경우에는 사출물 자체에 진주색상의 무늬가 전체에서 계속하여 부분적으로 연출되지 않고 지극히 일부분에 한정하여 연출될뿐만 아니라 표면의 광택이 급히 떨어지는 문제점이 있어서 원하는 만큼의 품질을 나타나지 않은 문제점이 있었다.When the polymethyl methacrylate acrylic resin (POLY METYL METHACRYLATE ACRYLIC RESIN) is 75wt% or more and the styrene butadiene copolymerized transparent resin (STYRENE BUTADIENE COPOLYMERS CLEAR RESIN) is formed and mixed and injected, the pearly pattern on the injection molding itself. There is a problem in that not only continue to be partially produced in the whole, but only limited to a very limited part, and the gloss of the surface is rapidly dropped, so that the quality does not appear as desired.

또한 이송실린더의 온도가 170℃이하를 유지하는 경우에는 혼합물이 이송을 행하면서도 접촉하는 열에 의해 완전한 반죽상태를 유지하지 않을 뿐만 아니라 부분적으로는 원재료의 형태인 펠렛(Pellet)으로 사출되는 문제점이 있다.In addition, when the temperature of the transfer cylinder is maintained below 170 ℃ not only does not maintain the complete dough state by the heat of contact while the mixture is transferred, there is a problem that is partially injected into the pellet (Pellet) in the form of raw materials .

그리고 이송실린더의 온도가 230℃이상을 유지하는 경우에는 반죽물이 완전히 액상화된 겔상태로 변화되어 금형에서의 성형이 어려운 문제점이 있었다.In addition, in the case where the temperature of the transfer cylinder is maintained at 230 ° C. or more, the dough is changed into a completely liquefied gel state, and thus molding in the mold is difficult.

폴리 메틸 메타 크레이트 아크릴 수지(POLY METYL METHACRYLATE ACRYLIC RESIN) 60wt%와 스티렌 부타디엔 공중합 투명수지(STYRENE BUTADIENE COPOLYMERS CLEAR RESIN) 40wt%이 되도록 총중량 30㎏과 약간의 분홍색 안료를 투입하여 혼합기에 투여하여 1시간동안 혼합하여 혼합물을 얻었다.30 kg of total weight and a little pink pigment are added to the mixer for 1 hour to make 60 wt% of POLY METYL METHACRYLATE ACRYLIC RESIN and 40 wt% of STYRENE BUTADIENE COPOLYMERS CLEAR RESIN. Mixing gave a mixture.

이러한 혼합물을 온도 200℃의 상태를 유지하는 이송실린더에서 강제로 이송시키는 것에 의해 상기한 혼합물을 혼합시키면서 반죽상태로 겔화시키면서 사출하는 즉시 머리핀형상의 금형에 투입하여 성형한 성형물(머리핀)을 얻었다.This mixture was forcibly transferred in a transfer cylinder maintained at a temperature of 200 ° C., and then injected into a hairpin mold as soon as it was injected while gelling into a kneading mixture while mixing the above mixture to obtain a molded article (hairpin).

이러한 성형물은 시각으로 관찰하였더니 분홍색 바탕의 성형물위에 불규칙한 진주색상의 무늬가 부분적으로 연출되었다.그리고, 종래와 같이 아크릴로니트릴 부타디엔 스틸렌 수지(A.B.S 수지; Acrylonitrile Butadiene Styrene Resin)와 분홍색 안료를 투입하여 제조한 머리핀과 육안으로 비교하였다.본 발명에 의한 성형물은 하기의 비교사진 1에서와 같이 성형물에서 분홍색바탕에 불규칙한 진주색상의 무늬가 부분적으로 연출된 반면에 종래의 머리핀은 단순히 분홍색 안료에 의한 색상을 가진 제품에 불과하여 외관상 확연한 차이점을 발견할 수 있었다.These moldings were visually observed, and the irregular pearl-colored patterns were partially produced on the pink-based moldings. And, conventionally, acrylonitrile butadiene styrene resin (ABS resin; Acrylonitrile Butadiene Styrene Resin) and pink pigment were added. The hairpin according to the present invention was visually compared with the prepared hairpin. In the molding according to the present invention, irregular pearl-colored patterns were partially produced on the pink base in the molding, whereas the conventional hairpin was simply colored by pink pigment. Only products with a significant difference in appearance were found.

이러한 혼합물을 온도 200℃의 상태를 유지하는 이송실린더에서 강제로 이송시키는 것에 의해 상기한 혼합물을 혼합시키면서 반죽상태로 겔화시키면서 사출하는 즉시 머리핀형상의 금형에 투입하여 성형한 성형물(머리핀)을 얻었다.이러한 성형물은 시각으로 관찰하였더니 초록색 바탕의 성형물위에 불규칙한 진주색상의 무늬가 부분적으로 연출되었다.그리고, 종래와 같이 아크릴로니트릴 부타디엔 스틸렌 수지(A.B.S 수지; Acrylonitrile Butadiene Styrene Resin)와 초록색 안료를 투입하여 제조한 머리핀과 육안으로 비교하였다.본 발명에 의한 성형물은 하기의 비교사진 5에서와 같이 성형물에서 초록색바탕에 불규칙한 진주색상의 무늬가 부분적으로 연출된 반면에 종래의 머리핀은 단순히 분홍색 안료에 의한 색상을 가진 제품에 불과하여 외관상 확연한 차이점을 발견할 수 있었다.This mixture was forcibly transferred in a transfer cylinder maintained at a temperature of 200 ° C., and then injected into a hairpin mold as soon as it was injected while gelling into a kneading mixture while mixing the above mixture to obtain a molded article (hairpin). These moldings were visually observed, and the irregular pearl-colored pattern was partially produced on the green-based molding. As in the prior art, acrylonitrile butadiene styrene resin and green pigment were added. The hairpin according to the present invention was visually compared with the prepared hairpin. In the molding, as shown in Comparative Photo 5, irregular pearl-colored patterns were partially produced on the green ground, whereas the conventional hairpin was simply colored by pink pigment. Apparently clear car with only a product I was able to find that.

이상 상기에서 살핀 바와같이 본 발명에 의하면 성질이 서로 다른 폴리 메틸 메타 크레이트 아크릴 수지(POLY METYL METHACRYLATE ACRYLIC RESIN)와 스티렌 부타디엔 공중합 투명수지(STYRENE BUTADIENE COPOLYMERS CLEAR RESIN)를 혼합하여 일정한 온도를 가진 이송실린더에서 강제로 혼합시키면서 압출하여 얻은 사출물에서 불특정한 진주색상의 무늬가 부분적으로 연출되게함으로서 종래에 상기와 같은 불특정한 진주색상의 무늬를 연출하기 위해서 고가의 진주분말을 사용하여야 하는 경제적 단점을 완전히 해결하여 장신구은 물론이고 장식품, 각종 인형등의 합성수지재를 원재료로 사용하는 모든 상품에 널리 사용할 수 있는 매우 유용한 발명임이 명백하다.As described above, according to the present invention, a polymethyl methacrylate acrylic resin (POLY METYL METHACRYLATE ACRYLIC RESIN) and styrene butadiene copolymerized transparent resin (STYRENE BUTADIENE COPOLYMERS CLEAR RESIN) are mixed in a transfer cylinder having a constant temperature. Particularly, the non-specific pearl-colored pattern is partially produced in the injection molded product obtained by extruding by mixing forcibly, thereby completely solving the economic disadvantage of using expensive pearl powder in order to produce the non-specific pearl-colored pattern as described above. Obviously, it is a very useful invention that can be widely used for all products using synthetic resin materials such as ornaments, various kinds of dolls as raw materials.
