본 발명은 열 전사무늬 아크릴코팅 인조 대리석 성형물의 제조방법에 관한 것으로서, 더 상세하게는 다양한 삼차원 형상을 갖는 성형물을 인조대리석을 이용하여 제조할 수 있도록 함과 아울러 제조된 성형물에 다양한 무늬를 연출할 수 있도록 하는 열 전사무늬 아크릴코팅 인조 대리석 성형물의 제조방법에 관한 것이다.The present invention relates to a method for manufacturing a heat transfer pattern acrylic coated artificial marble molding, and more particularly, it is possible to produce a molding having a variety of three-dimensional shape using artificial marble and to produce various patterns on the manufactured molding. It relates to a method for producing a heat transfer pattern acrylic coating artificial marble molding.

근래에는 건축 인테리어 내장용으로 인조대리석이 많이 사용되고 있으며, 이러한 인조대리석은 베이스 레진에 따라 불포화 폴리에스터계 인조대리석과 아크릴계 인조대리석으로 구분된다.In recent years, artificial marble has been used a lot for interior construction, and these artificial marbles are classified into unsaturated polyester artificial marble and acrylic artificial marble according to the base resin.

상기 불포화 폴리에스터계 인조대리석은 성형이 용이하여 욕조, 세면기 등 성형품에 많이 상용되나 가공의 난이성으로 인해 사용이 제한되고 있다. 이에 비해 아크릴계 인조대리석은 수지의 투명성으로 인해 색상의 미려함과 고급스런 질감을 표출하고, 특히 목공용 가공기계 등을 사용할 수 있는 가공성이 뛰어나 인테리어 분야에서 널리 사용되고 있는 것이다. The unsaturated polyester-based artificial marble is widely used in molded products such as baths and washbasins due to easy molding, but its use is limited due to the difficulty of processing. On the other hand, acrylic artificial marble expresses the beauty of the color and the luxurious texture due to the transparency of the resin, and is widely used in the interior field because of its excellent workability that can be used for woodworking processing machines.

한편, 욕조, 세면기 등은 앞서 본 바와 같이 불포화 폴리에스터계 레진을 원료로 하여 제조되는바, 이와 같은 삼차원 형상의 성형물을 제조할 때에는 상기와 같이 불포화 폴리에스터계 레진으로 제조된 인조대리석 판재에 열을 가한 후 지정 금형에 장착한 다음 진공으로 빨아들여 형태를 만들고, 이후 냉각하여 소정의 형상으로 성형 되면 마지막으로 스프레이 건으로 유리섬유와 무기 충전물을 분사하여 제조하고 있는 실정이다. On the other hand, bathtubs, washbasins, etc. are made of unsaturated polyester resin as a raw material as described above, when manufacturing a three-dimensional molded article as described above is heated in artificial marble plate made of unsaturated polyester resin as described above After adding to the designated mold and sucked in a vacuum to form a shape, and then cooled and molded into a predetermined shape is finally produced by spraying glass fiber and inorganic filler with a spray gun.

상기에 따라 제조된 성형물은 일반적으로 3~8mm의 두께로 형성되는 것이며, 전체 두께 중 스프레이 건에 의해 도포 되는 유리섬유와 무기 충전물의 두께는 3~5mm가 되는 것이다. 이는 스프레이를 사용함에 따라 두께의 조절이 힘들기 때문 에 주로 적용되고 있는 두께로서, 요구되는 강도를 구현하기 위한 최소의 두께에 불과한 것이다. The molded article prepared according to the above is generally formed to a thickness of 3 ~ 8mm, the thickness of the glass fiber and the inorganic filler applied by the spray gun of the total thickness is 3 ~ 5mm. This is the thickness that is mainly applied because it is difficult to control the thickness by using the spray, it is only a minimum thickness to achieve the required strength.

그러나, 상기와 같은 종래 방식에 의하면 스프레이로 분사함에 따라 일정 두께 이상으로 성형하기가 어렵다는 단점이 있는 것이었으며, 균일한 두께로 형성하기도 쉽지 않은 단점이 있는 것이었다. 특히 표면에 무늬를 성형하기가 어려워 유백색과 같은 단색의 제품으로 제조되는바, 단조로울 수밖에 없는 외관을 지니게 되어 인테리어 업계의 다변하는 욕구에 신속하게 대응하는 미적 감각을 지닌 제품을 구성하기가 어렵다는 단점이 있는 것이었다. However, according to the conventional method as described above, there is a disadvantage in that it is difficult to form a predetermined thickness or more by spraying, and there is a disadvantage that it is not easy to form a uniform thickness. In particular, since it is difficult to form a pattern on the surface, it is manufactured with a monochromatic product such as milky white, which has a monotonous appearance, making it difficult to construct a product having an aesthetic sense quickly responding to various needs of the interior industry. It was.

본 발명은 상기와 같은 종래 불포화 폴리에스터 레진을 이용하여 제조하는 성형품이 가진 문제점을 해결하기 위해 안출된 것으로서, 제품 자체에 다양한 무늬를 형성할 수 있도록 하여 미적 가치를 향상시키고, 더불어 두께 조절이 자유로워 필요에 따라 다양한 두께의 제품 생산이 가능할 뿐만 아니라 일정한 두께로 성형이 가능하여 내구성이 향상된 성형물을 자유롭게 제작할 수 있도록 하는 인조 대리석 성형물의 제조방법을 얻는데 그 목적이 있는 것이다.The present invention has been made to solve the problems of the molded article manufactured by using the conventional unsaturated polyester resin as described above, to form a variety of patterns on the product itself to improve the aesthetic value, and also to control the thickness freely It is an object of the present invention to obtain a method of manufacturing artificial marble moldings that can produce products of various thicknesses as required, as well as molding them to a certain thickness so as to freely manufacture molded articles having improved durability.

이하 본 발명을 첨부된 도면을 참고로 하여 상세하게 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 의한 인조 대리석 성형물의 제조 단계를 보여주는 공정도이고, 도 2는 본 발명에 의한 인조 대리석을 성형하는 과정을 단면으로 하여 개략적으로 보여주는 실시 과정도로서, 각 제조 단계에 따른 공정을 보여주고 있다.1 is a process chart showing a manufacturing step of the artificial marble molding according to the present invention, Figure 2 is a schematic view showing the cross-sectional process of forming the artificial marble according to the present invention, the process according to each manufacturing step Is showing.

본 발명은 무늬형성단계(100)와 가열단계(200)와 성형단계(300)와 주조단계(400)와 탈형단계(500)를 차례로 수행하되, 탈형단계(500) 이후 요구되는 강도 확보를 위한 후처리단계(600)를 더 수행할 수 있다. 이를 각 단계별로 살펴 본 발명의 제조방법을 상세히 살펴본다.The present invention performs the pattern forming step 100 and the heating step 200 and the forming step 300 and the casting step 400 and the demolding step 500, in order to ensure the strength required after the demolding step 500 The post-processing step 600 may be further performed. It looks at each step in detail the manufacturing method of the present invention.

[Ⅰ] 무늬형성단계(100)[Ⅰ] Pattern formation stage (100)

이 단계에서는 미리 일정한 크기로 준비된 투명 아크릴판(10)에 무늬지(20)를 열 전사하여 무늬를 형성하게 된다. 아크릴판(10)에 무늬지(20)를 맞댄 후 프레스 등을 통해 180~200℃로 열을 가함과 동시에 압력을 가하게 되면 무늬지(20)에 형성된 무늬가 아크릴판(10)에 전사되는 것이다[도 2a].In this step, the patterned paper 20 is thermally transferred to the transparent acrylic plate 10 prepared in a predetermined size to form a pattern. The pattern formed on the patterned paper 20 is transferred to the acrylic plate 10 when the patterned paper 20 is brought back to the acrylic plate 10 and then heated at 180 to 200 ° C. through a press. 2a.

[Ⅱ] 가열단계(200)[II] Heating step (200)

상기 무늬형성단계(100)를 통해 투명 아크릴판(10)에 무늬가 형성되면 이를 다시 가열하여서 연화하게 된다. 가열 온도는 180~220℃의 온도이고, 3~10분 동안 지속적으로 가열하여 아크릴판(10)이 충분히 연화되도록 하여 주는 것이다. 아크릴판(10)을 연화하는 것은 후술하는 성형단계(300)에서 진공흡입을 통해 성형하기 위한 것이다.When a pattern is formed on the transparent acrylic plate 10 through the pattern forming step 100, it is heated and softened again. The heating temperature is a temperature of 180 ~ 220 ℃, to continuously heat for 3 to 10 minutes to allow the acrylic plate 10 is soft enough. Softening the acrylic plate 10 is for molding through vacuum suction in the molding step 300 to be described later.

[Ⅲ] 성형단계(300)[III] Molding Step (300)

상기 가열단계(200)에서 연화된 아크릴판(10)은 몰드(30)에서 가공하여 3차원 입체형상으로 형성하게 된다. 몰드(30)는 세면대의 형상, 욕조의 형상과 같은 3차원 입체형상을 구현할 수 있도록 구성되어 있는 것으로서, 연화된 아크릴판(10)을 상기 몰드(30)의 입구에 올려놓아 장착한 다음 몰드(30) 내부의 공기를 흡입하게 되면 연화된 아크릴판(10)에 변형이 생기면서 원하는 형상으로 성형하는 구성이다. 진공 흡입 성형을 하기 위해서는 몰드(30)의 바닥면에 다수개의 흡입공을 형성하고 도시되지 않은 외부 흡입장치를 통해 몰드(30) 내부의 공기를 흡입하여 연화된 아크릴판(10)이 몰드(30)의 형상대로 성형 되도록 하는 것이며, 상기에 따라 제조하고자 하는 성형물(60)의 기본 형상이 결정되는 것이다[도 2b, 도 2c]. The acrylic plate 10 softened in the heating step 200 is processed in the mold 30 to form a three-dimensional solid shape. Mold 30 is configured to implement a three-dimensional solid shape, such as the shape of the sink, the shape of the bathtub, the soft acrylic plate 10 is mounted on the inlet of the mold 30, and then the mold ( 30) When the air is sucked inside, the softened acrylic plate 10 is deformed and molded into a desired shape. In order to perform vacuum suction molding, a plurality of suction holes are formed on the bottom surface of the mold 30, and the acrylic plate 10 softened by sucking the air inside the mold 30 through an external suction device (not shown) forms the mold 30. ), And the basic shape of the molding 60 to be manufactured is determined according to the above (Fig. 2B, Fig. 2C).

[Ⅳ] 주조단계(400)[IV] Casting step (400)

상기 성형단계(300)를 통해 성형물(60)의 기본 형상이 결정되면 몰드(30)와 한조를 이루되 제작될 성형물(60)의 내부 형상을 결정하는 덮개틀(40)을 몰드(30)의 상부에 덮어주게 된다[도 2d]. 이때 몰드(30)의 가장자리에는 턱(32)이 형성되 어 있어서 상기 덮개틀(40)을 덮어줄 경우 전술한 성형단계(300)에서 성형된 성형물(60)과 일정 간격이 벌어지도록 하고 있다. 이 구성을 통해 슬러리(50)를 부어 넣을 경우 그 벌어진 간격만큼의 두께를 형성할 수 있게 됨과 아울러, 성형 될 제품의 두께를 균일하게 형성할 수 있게 되는 것이다. When the basic shape of the molding 60 is determined through the molding step 300, the cover frame 40 determines the inner shape of the molding 60 to be manufactured in a group with the mold 30. The top is covered (Fig. 2d). At this time, the jaw 32 is formed at the edge of the mold 30 so that the cover frame 40 is covered with a predetermined distance from the molded product 60 formed in the aforementioned forming step 300. Through this configuration, when the slurry 50 is poured, the thickness of the gap can be formed and the thickness of the product to be formed can be uniformly formed.

상기 덮개틀(40)의 간격은 턱(32)의 높이를 조절하여 다양하게 조절할 수 있는바, 성형 될 제품에 따라 선택적으로 결정하며, 통상 12~30mm정도가 될 것이다. 한편, 상기 덮개틀(40)의 중앙 부에는 주입구(42)가 형성되어 있는데, 이 주입 구(42) 통해 주물을 제작하듯이 탱크에 충입 되어 있는 슬러리(50)를 주입하여 주게 되는 것이다[도 2e].The interval of the cover frame 40 can be adjusted in various ways by adjusting the height of the jaw 32, it is determined selectively depending on the product to be molded, will usually be about 12 ~ 30mm. On the other hand, an injection hole 42 is formed in the central portion of the cover frame 40, which is to inject the slurry 50 filled in the tank as if the casting through the injection hole 42 (Fig. 2e].

여기서, 상기 슬러리(50)는 일반적으로 제조되는 것을 적용할 수 있다. 예로, 본 발명에 적용되는 슬러리(50)의 대략적인 구성을 보면, 주재료로 사용되는 분말(수산화알루미늄, 실리카, 탄산칼슘, 백운석, 황토가루, 옥돌가루 등 인체에 유해하지 않은 다양한 물질의 분말을 하나 또는 그 이상 혼합한 것) 60~80중량%와, 접착제 역할을 하며 시간이 흘러 경화되는 액상의 물질(불포화 폴리에스터 레진 또는 아크릴 중합 불포화에스터 레진) 15~40중량%, 그리고 마치 화강암과 같이 보여 대리석과 같은 느낌을 줄 수 있도록 하는 마블칩 1~20중량%, 색상을 내기 위한 연료 및 안료 0.1~5중량%로 구성되며, 기타 미량의 분산제, 가교제 등을 첨가하여 혼합하여 준 것이다. In this case, the slurry 50 may be generally manufactured. For example, in the schematic configuration of the slurry 50 applied to the present invention, the powder used as the main material (aluminum hydroxide, silica, calcium carbonate, dolomite, loess powder, jade powder, etc. 60 to 80% by weight of one or more), 15 to 40% by weight of a liquid substance (unsaturated polyester resin or acrylic polymer unsaturated unsaturated resin) that acts as an adhesive and hardens over time, and granite Marble chip 1 ~ 20% by weight to give a marble-like feel, and fuel and pigment 0.1 ~ 5% by weight for coloring, and other small amount of dispersing agent, crosslinking agent, etc. were added and mixed.

[Ⅴ] [Ⅴ] 탈형단계Demolding stage (500)(500)

상기 주조단계(400)를 거쳐 성형물(60)이 성형되면 주입된 슬러리(50)의 경 화를 위해 10~40분 동안 기다렸다가 탈형을 하게 된다. 덮개틀(40)을 제거한 후 성형물(60)을 몰드(30)에서 탈형하게 되는 것이다. 이후 상기 성형물(60)에서 불필요한 부분들을 갈아내고 다듬어서 완성하게 되는 것이다[도 2f].When the molding 60 is molded through the casting step 400, the mold 60 is waited for 10 to 40 minutes for curing of the injected slurry 50, and then demolded. After the cover frame 40 is removed, the molding 60 is demolded from the mold 30. After that, to grind and trim the unnecessary parts in the molding 60 is completed (Fig. 2f).
