Description

옥돌무늬를 형성시킨 인조대리석의 제조방법{manufacturing method of artificial marble}Manufacturing method of artificial marble with jade stone pattern

본 발명은 인조대리석의 제조방법에 관한 것으로서, 더욱 상세하게는 옥돌과 같은 천연 대리석의 은은하고 깊이 있는 질감을 표현할 수 있는 인조대리석의 제조방법에 있어, 제조방법이 보다 간단하고 제품의 파손이 발생될 경우 원상복구가 가능하도록 한 옥돌무늬를 형성시킨 인조대리석의 제조방법에 관한 것이다.The present invention relates to a method of manufacturing artificial marble, and more particularly, to a method of manufacturing artificial marble capable of expressing a subtle and deep texture of natural marble such as jade, the manufacturing method is simpler and product breakage may occur. In this case, the present invention relates to a method of manufacturing artificial marble in which an jade stone pattern is formed to allow restoration of original form.

일반적으로 옥돌은 그 무늬가 호화롭고 영롱하여 최고급 대리석 층에 해당되어 이미 그 개발단계가 한계점에 이르러 고갈되어 가는 형편이며, 또한 엄청난 가격으로 수입되고 있다.In general, the jade is luxurious and glorious, which is the highest level of marble, and the stage of development is already depleted to the limit, and is imported at a great price.

국내에서도 몇몇 광산에서 생산되고는 있지만 질이 외국산에 비해 훨씬 뒤떨어지고 자원량이 많지 않은데다가 정부의 자연보호정책에 의해 개발이 제한되고 있는 형편이다.Although it is produced in some mines in Korea, its quality is much lower than that of foreign production, and its resources are not much. Also, its development is restricted by the government's nature protection policy.

이에 인공으로 옥돌을 재현하는 기술을 오랜 기간 동안에 연구 개발되어져 오고 있다.Therefore, the technology of artificially reproducing jade has been researched and developed for a long time.

인조대리석은 다양한 색상을 표현할 수 있다는 장점과 더불어 내열성이 높고, 미려한 표면의 외관과 내마모성 및 충격강도가 높고, 또한 가정용 세제나 화학약품에 대한 내구성이 우수하여 세면기, 씽크대, 욕조 등 가정에서 사용하는 성형품에 주로 이용되어져 오고 있다.Artificial marble has the advantage of expressing various colors, high heat resistance, beautiful surface appearance, high abrasion resistance and impact strength, and excellent durability for household detergents or chemicals. It is mainly used for molded articles.

옥돌무늬를 형성시키기 위한 인조대리석 제조하기 위한 종래의 방법으로서는 다음과 같다.Conventional methods for producing artificial marble for forming jade stones are as follows.

투명 겔코트를 성형틀에 1차 코팅하여 상온에서 경화시킨 다음 2차 투명 겔코트를 도포하고, 부직포(대리석무늬) 또는 도포된 겔코트에 접착하여 성형틀에 고정시킨 다음 반죽(합성수지 + 충진제)을 원하는 두께로 충진하여 상온 경화시킴으로서 얻는 방법을 들 수 있는데, 이와 같은 방법은The transparent gel coat was first coated on the mold to cure at room temperature, and then the second transparent gel coat was applied, adhered to the nonwoven fabric (marble pattern) or the applied gel coat, and fixed to the mold, and then kneaded (synthetic resin + filler). It can be obtained by filling in the desired thickness to cure at room temperature.

1차 코팅후 2차 코팅하여 부직포 또는 전사지를 증착시키는 공정에서, 두께가 고르지 않은 상태에서 증착시키게 되면 1차 코팅된 겔코트가 용해되어 표면이평활하지 못하고 일그러지게 되는 문제점이 있었고,In the process of depositing the nonwoven fabric or the transfer paper by the first coating after the second coating, when the thickness is deposited in an uneven state, the first coated gel coat is dissolved and the surface is not smooth and distorted.

또한 1차 코팅과 2차 코팅이 완전히 경화된 상태에서 부직포 또는 전사지의 증착공정에 임해야 하지만 경화시간이 길뿐만 아니라 작업조건이 까다로워 작업효율의 저하 및 불량율이 커지게 되는 문제점이 있었으며,In addition, the primary coating and the secondary coating must be in the process of depositing nonwoven fabric or transfer paper in the completely cured state, but the curing time is long and the working conditions are difficult, resulting in a decrease in the work efficiency and a high defect rate.

또한 부분 파손시 보수하기가 난해하고, 보수할 경우 흔적이 남게 문제점 및In addition, it is difficult to repair in case of partial damage, and the problem remains after the repair

부직포 또는 전사지에 의한 무늬는 프린트된 무늬로써 깊이가 있고 은은한 천연 옥돌무늬의 질감을 표현할 수 없는 문제점이 있었다.The pattern by the nonwoven fabric or transfer paper has a problem that can not express the texture of the natural jade pattern is deep and subtle as a printed pattern.

따라서 본 발명은 상기의 제반문제를 해결하기 위해 창출된 것으로서 그 목적은 옥돌과 같은 천연 대리석의 은은하고 깊이 있는 질감을 표현할 수 있는 인조대리석의 제조방법에 있어, 제조방법이 보다 간단하고 제품의 파손이 발생될 경우 원상복구가 가능하도록 한 옥돌무늬를 형성시킨 인조대리석의 제조방법을 제공함에 있다.Therefore, the present invention was created to solve the above problems, and its purpose is to produce artificial marble which can express the subtle and deep texture of natural marble such as jade, and the manufacturing method is simpler, and the damage of product It is to provide a method of manufacturing artificial marble in which the jade stone pattern is formed so that it can be restored to the original when generated.

[실시예]EXAMPLE

첨부도면에서 도시된 바와 같이 옥돌무늬가 형성된 인조대리석을 형성시키는 방법에 있어서, 먼저 상기의 인조대리석을 성형하기 위해 하부 성형틀(10)과 상부 성형틀(20)이 기본적으로 구비된 상태에서, 상기 하부 성형틀(10)의 일면에 왁스처리한 이형층(12)을 형성하고, 그 이형층(12)에 표면광택 및 표면강도, 흡수율 억제를 높이는 약품인 투명 겔코트(14)를 도포하여 경화한다. 본 발명의 실시예에서의 바람직한 도포두께는 0.03mm∼0.05mm, 온도는 상온 20∼25℃, 시간은 15분 정도가 적당하다.In the method of forming an artificial marble having an jade stone pattern as shown in the accompanying drawings, in order to form the artificial marble first, in a state in which the lower mold 10 and the upper mold 20 is basically provided, Wax-treated release layer 12 is formed on one surface of the lower mold 10, and the transparent gel coat 14, which is a chemical agent for enhancing surface gloss, surface strength, and absorption inhibition, is applied to the release layer 12. Harden. Preferable coating thickness in the Example of this invention is 0.03 mm-0.05 mm, temperature is 20-25 degreeC of normal temperature, and time is about 15 minutes.

이 후 옥돌가루 + 알루미나 + 글라스 후리트를 투명 합성수지와 작업하기에 알맞은 점도(바람직하게는 2:1)로 반죽한 충진재를 만들게 되는데, 상기 충진재는 옥돌무늬를 만들기 위한 재료로써, 옥돌무늬의 바탕색이 되는 바탕색 충진재(16a)와 옥돌고유의 무늬(패턴)을 표현하기 위해 무기질 안료나 황토, 옥돌가루 등을 추가로 혼합하되 혼합비율을 서로 달리함으로써 명도(明度)의 차이를 두게 한 2가지 이상 바람직하게는 3∼4가지의 무늬색 충진재(16b)를 준비한다.After that, a filler is prepared by kneading jade stone + alumina + glass frit with a transparent synthetic resin (preferably 2: 1), and the filler is a material for making an jade pattern, and the ground color of the jade pattern In order to express the ground color filler 16a and the jade stone-specific pattern (pattern), two or more inorganic pigments, ocher, jade powder, etc. may be additionally mixed, and the mixing ratios may be different from each other to give a difference in brightness. Preferably, three to four pattern color fillers 16b are prepared.

한편 접기 용이하고 찢어지지 않는 비닐종이(18)에 준비된 바탕색 충진재(16a)와 3∼4가지의 무늬색 충진재(16b)를 순차적으로 도포(명도가 큰 것은 많게, 명도가 작은 것은 소량)하되, 무늬색 충진재(16b)는 천연 옥돌무늬 형상과 같이 불규칙적인 패턴을 갖도록 주걱과 같은 도구로 조절한다.On the other hand, the base color filler 16a and 3 to 4 pattern color fillers 16b prepared on vinyl paper 18, which are easy to fold and are not torn, are sequentially applied (large brightness and small brightness). Filler 16b is adjusted with a tool such as a spatula to have an irregular pattern, such as a natural jade pattern.

이 후 상기 도포된 비닐종이(18)의 대향하는 두 변을 잡고 반으로 포개게 되는데, 이 때 각기 다른 명도의 무늬색 충진재(16b)는 희석되어 섞이지 않고 바탕색 충진재(16a)에 함침되며 이를 다시 데칼코마니 기법과 같이 비닐종이(18)를 원상태로 펼치게 되면 천연 옥돌무늬와 같이 깊이있고 은은한 무늬모양의 층이 형성되어지게 된다.Thereafter, the two opposite sides of the coated vinyl paper 18 are grabbed and overlapped in half. At this time, the patterned color fillers 16b of different brightness are diluted and impregnated with the background color fillers 16a, which are again mixed with decalcomani. When the vinyl paper 18 is unfolded as in the technique, a deep and subtle pattern like a natural jade pattern is formed.

이와 같이 펼쳐진 비닐종이(18)의 충진부분에 국부적으로 바람을 이용하여 재차 무늬를 조정할 수 있다.Thus, the pattern can be adjusted again by using wind locally on the filled portion of the unfolded vinyl paper 18.

다음 공정으로서, 하부 성형틀(10)에 도포시킨 겔코트(12)면에 비닐종이(18)에 도포시킨 충진재를 부착시킨 다음 그 비닐종이(18)를 제거한다.As a next step, the filler coated on the vinyl paper 18 is attached to the surface of the gel coat 12 applied on the lower mold 10, and then the vinyl paper 18 is removed.

상기 비닐종이(18)를 제거하게 되면 제거면이 평활하지 못하는 상태가 되는데 이를 해소하기 위해 상부 성형틀(20)에 이형층(22)을 형성하고 그 층 위에 별도의 충진재(24)를 도포한 상태에서 하부 성형틀(10)과 상부 성형틀(20)을 서로 맞추어 일정한 조건 즉 상온 25℃, 약 20∼30분의 경화시간에서 경화시킨 다음 탈형하면 본 발명의 인조대리석이 완성된다.When the vinyl paper 18 is removed, the removal surface is not smooth. In order to solve this problem, a release layer 22 is formed on the upper mold 20 and a separate filler 24 is coated on the layer. When the lower mold 10 and the upper mold 20 is matched with each other in a state of curing under constant conditions, that is, a curing time of about 25 ℃, about 20 to 30 minutes, and then demolded, the artificial marble of the present invention is completed.

이상에서 설명한 본 발명은 전술한 실시예 및 첨부된 도면에 의해 한정되는 것이 아니고, 본 발명의 기술적 사상을 벗어나지 않는 범위 내에서 여러 가지 치환, 변형 및 변경이 가능하다는 것이 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에게 있어 명백할 것이다.The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible in the art without departing from the technical spirit of the present invention. It will be clear to those of ordinary knowledge.

이상에서와 같은 본 발명은 겔코트를 경화시키는 1차 공정의 진행상태에서 바탕색충진재 및 무늬색 충진재를 준비시키는 2차 공정, 비닐종이에 준비된 충진재를 도포하는 3차 공정을 동시에 진행시킬 수 있고 종래에 비해 상대적으로 작업이 간단하기 때문에 작업시간 및 작업효율이 종래에 비해 개선될 수 있을 뿐만 아니라 본 발명의 옥돌무늬는 표면뿐만 아니라 심층에서도 동일한 무늬가 형성되어져 있기 때문에 크랙이나 부분파손이 발생된다 하더라도 그라인딩 작업을 통해서 그 문제점을 해소할 수 있는 장점이 있다.As described above, the present invention can proceed simultaneously with the secondary process of preparing the background color filler and the patterned color filler in the progress of the primary process of curing the gel coat, and the third process of applying the filler prepared on the vinyl paper. Compared with the conventional method, the work time and work efficiency can be improved since the work is relatively simple, and the jade stone of the present invention is ground even if cracks or partial damage are generated because the same pattern is formed not only on the surface but also on the deep layer. There is an advantage to solve the problem through work.
