본 발명은 자연석의 색상 및 문양이 표현되는 합성수지 판넬의 제조방법에 관한 것이다.The present invention relates to a method for producing a synthetic resin panel in which the color and pattern of natural stone is expressed.

색상과 무늬가 아름다운 자연석은 고급 건축재로서 널리 사용되고 있으나 매장량의 희소성과 제품의 가공 및 양산의 어려움이 따르므로 욕조나 세면대 벽면용 판넬의 용도에는 자연석 대신 합성수지가 선호되고 있다.Natural stone with beautiful colors and patterns is widely used as a high-grade building material, but due to the scarcity of reserves and the difficulty of processing and mass-producing products, synthetic resins are preferred to natural stone instead of natural stone.

일반의 합성수지재 욕조나 세면대, 씽크대, 벽면판넬등은 대체로 단일 색상으로 제조되고 있는 바, 이러한 단일색조는 정서적으로 단조로운 느낌을 주므로 자연석의 아름다운 색상과 문양을 가미한다면 보다 미려하고 고급스러운 분위기를 연출할 수 있을 것이다.General synthetic resin bathtubs, sinks, sinks, wall panels, etc. are generally manufactured in a single color, and these single tones give an emotionally monotonous feeling, so if you add beautiful colors and patterns of natural stone, you can create a more elegant and luxurious atmosphere. Could be.

현재까지 알려진 무늬 및 색상 형성방법은 색상이 다른 수지용액을 적당한 농도에서 혼합하여 성형틀에 주입한 후 성형하는 정도에 머물고 있다.The pattern and color forming method known to date is mixed with resin solutions of different colors at an appropriate concentration, and then injected into a molding mold to maintain the molding.

이러한 방법은 자연석이 가지는 자연스럽고 오묘한 문양 및 색상을 표현하기가 불가능하고 평면 판넬이 아닌 곡면의 성형물에 있어서는 부위에 따라 교반흔적이 드러나는 치명적인 결함을 나타내고 있다.This method is not able to express the natural and mysterious patterns and colors of natural stone, and exhibits a fatal defect in which the stir traces are revealed depending on the part of the curved molded part that is not a flat panel.

본 발명은 재질은 합성수지로 하되 마치 자연석과 같은 무늬와 색상을 갖는 합성수지 제품을 제조할 수 있는 방법을 제공하고자 하는 것이다.The present invention is intended to provide a method for producing a synthetic resin product having a pattern and color, such as natural stone, but the material is a synthetic resin.

제1도는 본 발명의 공정을 나타낸 것이고, 제2도는 본 발명 제품의 단면도를 예시한 것으로서, 도면을 참조해서 본 발명의 제조방법을 자세히 설명하기로 한다.Figure 1 shows the process of the present invention, Figure 2 illustrates a cross-sectional view of the product of the present invention, with reference to the drawings will be described in detail the manufacturing method of the present invention.

[제1공정(표면 투명층 코우팅 공정)][First Process (Surface Transparent Layer Coating Process)]

하부 성형틀의 표면에 겔 상태의 투명한 합성수지 혼합물 용액을 분사기로 고르게 도포하여 광택이 있고 투명한 표면 투명층(1)을 형성한다.A gel-like transparent synthetic resin mixture solution is evenly applied on the surface of the lower mold to form a glossy and transparent surface transparent layer 1.

표면 투명층(1)의 두께는 1~2m/m정도가 바람직하다.As for the thickness of the surface transparent layer 1, about 1-2 m / m is preferable.

투명한 겔 상태의 합성수지 혼합물은 중량비로 수지 98.2%에 대하여 경화제 1%, 경화촉진제 0.8%를 첨가하여 충분히 교반하여 사용하는 것이다.The transparent gel-like synthetic resin mixture is used by sufficiently adding 1% of a curing agent and 0.8% of a curing accelerator to 98.2% of the resin by weight.

[제2공정(자연석 문양층 형성공정)][2nd process (Natural stone pattern layer forming process)]

표면 투명층(1)은 하부 성형틀에 코우팅하고 5~15분이 경과한 후 표현하고자 하는 자연석의 무늬를 표면 투명층(1) 이면에 가늘게 분사하여 줄무늬를 도포하여 자연석 문양층(2)을 형성한다.The surface transparent layer (1) is coated on the lower mold, and after 5 to 15 minutes, the pattern of natural stone to be expressed is sprayed thinly on the back surface of the surface transparent layer (1) to apply stripes to form a natural stone pattern layer (2). .

물론, 자연석 문양층(2)은 여러 가지 문양을 표현할 수 있는 것으로, 줄무늬의 색상은 표현하고자 하는 자연석 줄무늬의 색상과 동일한 것으로 한다.Of course, the natural stone pattern layer (2) can express a variety of patterns, the color of the stripes to be the same as the color of the natural stone stripes to be expressed.

미술적 감각을 갖춘 사람이면 수공으로 색상이 부여된 수지용액을 분사하여 줄무늬를 그려 넣을 수 있으며, 양산을 위해서는 줄무늬의 변화를 컴퓨터에 입력하여 로봇 아암(Arm)으로 색채수지용액을 분사하여 자연석과 흡사한 문양을 표현한다.If you have an artistic sense, you can draw stripes by spraying colored resin solution by hand, and for mass production, change the stripes into the computer and spray the color resin solution with the robot arm. Expressing similar patterns

이때, 분사기와 표면층의 거리 각 부분마다 분사기가 지체하는 시간(진행속도)에 따라 줄무늬의 선명도와 굵기가 결정된다.At this time, the sharpness and the thickness of the stripes are determined according to the time (progression speed) that the injector delays for each portion of the distance between the injector and the surface layer.

분사기로 색채수지용액을 분사하여 줄무늬를 표현하는 것은 매우 긴요한 수단으로서, 그 까닭은 일반적인 자연석의 줄무늬가 중심부는 뚜렷하고 주변부분은 점차 흐려지는 특성을 가지므로 이러한 줄무늬를 표현하는데는 스프레이로 줄무늬를 그려내는 것이 가장 적합하기 때문이다.It is very important to express the streaks by spraying the color resin solution with the injector. Because it is best to pay.

한편, 뚜렷한 색상의 줄무늬(금)가 나타나 있는 자연석이나 둥근 반점 모양의 무늬가 나타나 있는 자연석의 경우에는 스프레이로 무늬를 나타낼 수가 없으므로 스폰지에 가열된 금속봉으로 바탕부분을 녹여 문양부분만 돌출되게 스폰지 요철 블록을 여러 가지 문양으로 각인하여 수개의 요철블럭(인판)을 마련한다.On the other hand, in case of natural stone with distinct color stripes (gold) or natural stone with round spot pattern, it is impossible to display the pattern by spraying. The block is engraved with various patterns to prepare several bumps.

그리고 스폰지 요철블럭에 색채수지용액을 발라서 표면투명층(1)에 반복하여 찍어가며 프린팅한다.Then, a color resin solution is applied to the sponge uneven block and repeatedly printed on the surface transparent layer 1.

문양의 색상이 2가지인 경우에는 스폰지 요철블럭에 해당하는 색상의 수지용액을 발라 중복하여 프린팅한다.If the pattern has two colors, apply the resin solution of the color corresponding to the sponge uneven block and print it repeatedly.

스폰지는 프린팅에 적당한 탄성으로 가지며 압착시 균일한 프린팅이 가능하고 프린팅 상태가 자연석의 무늬가 가지는 섬세하고 자연스러운 조직구조를 나타내는데 가장 적합한 재료이다.Sponge has the elasticity suitable for printing and enables uniform printing when pressed, and the printing state is the most suitable material for showing the delicate natural structure of the natural stone pattern.

투명 표면층(1)은 끈적끈적한 상태이므로 무늬가 분사되거나 프린팅되면 색채 및 무늬가 화체되어 단일수지층과 같이 이루어진다.Since the transparent surface layer 1 is in a sticky state, when the pattern is sprayed or printed, the color and the pattern are ignited to form a single resin layer.

[제3공정(바탕색상층 형성공정)][3rd step (desk color layer forming step)]

자연석의 바탕을 이루는 색상과 같은 색채수지용액을 문양층의 이면에 분사기로 균일하게 분사한다.A color resin solution, such as the color that forms the basis of natural stone, is sprayed evenly with a sprayer on the back of the pattern layer.

그리고 바탕색이 진한 부분, 얼룩진 부분은 진한 색채의 수지용액을 분사하여 자연석의 바탕색과 동일하게 분사하여 바탕색상층(3)을 형성한다.The darker part of the background color and the stained part are sprayed in the same way as the natural color of the natural stone by spraying the resin solution of the dark color to form the ground color layer (3).

바탕색상층(3)의 수지용액은 수지와 경화제, 경화촉진제 약 20~25%에 대하여 수산화 알미늄, 규석분말, 글라스 프리트(glass frit) 약 75~80%(중량비)를 혼합한 것이다.The resin solution of the base color layer 3 is a mixture of about 75 to 80% (weight ratio) of aluminum hydroxide, silica powder and glass frit with respect to about 20 to 25% of the resin, the curing agent and the curing accelerator.

투명도를 높이기 위해서는 수산화 알미늄과 글라스 프리트의 혼합비를 높이고 불투명한 자연석의 경우에는 규석분말의 혼합비를 높인다.In order to increase transparency, the mixing ratio of aluminum hydroxide and glass frit is increased, and in the case of opaque natural stone, the mixing ratio of silica powder is increased.

바탕색상층(3)의 수지용액은 내부에서 발생하는 기포가 사라져 밀도가 높아지도록 충분히 그리고 효과적으로 교반되어야 한다.The resin solution of the background color layer 3 should be sufficiently and effectively stirred so that the bubbles generated therein disappear and the density becomes high.

[제4공정(수지주입 성형공정)][4th process (resin injection molding process)]

하부 성형틀에 상부 성형틀을 결합하고 주입구를 통하여 수지 및 분말석분 혼합물을 주입한다. 이때에도 경화제 및 경화촉진제가 동일한 방법으로 투여된다.The upper mold is coupled to the lower mold and the resin and powdered powder mixture is injected through the inlet. At this time, the curing agent and the curing accelerator are administered in the same manner.

[제5공정(탈형공정)][5th process (demolding process)]

상부 성형틀과 하부 성형틀을 순차적으로 탈형한다.The upper mold and the lower mold are sequentially demolded.

[제6공정(경화공정)]6th process (hardening process)

성형물이 충분히 경화되도록 80℃의 열풍건조실에서 2~3시간 경화시킨다.The cured product is cured in a hot air drying chamber at 80 ° C. for 2 to 3 hours to sufficiently cure the molded product.

상기의 공정으로 완성된 본 발명은 제3도에서와 같이 다양한 문양과 무늬를 형상화 할 수 있는 것이다.The present invention completed by the above process is capable of forming a variety of patterns and patterns as shown in FIG.

이상의 공정에서 제2공정 및 제3공정으로 제외한 나머지 공정들은 일반 합성수지 성형방법과 별다른 차이가 없다.In the above steps, the remaining steps except for the second step and the third step do not differ from the general synthetic resin molding method.

제2공정인 문양 색상층 형성공정과 제3공정인 바탕색상층 형성공정은 본 발명의 가장 핵심적인 기술로서 일반 합성수지 성형물과 다른 자연석 문양이 표현되는 공정인 것이다.The second step of the pattern color layer forming process and the third step of the background color layer forming process is the process of expressing the general synthetic resin molding and other natural stone patterns as the core technology of the present invention.

특히 스프레이 내지 분사에 의한 줄무늬 표현방법과 스폰지 요철블럭에 의한 반점 또는 금 간 무늬의 표현방법은 자연석 무늬형성에 있어서 가장 효과적인 수단이 되고 있다.In particular, the method of expressing the stripes by spraying or spraying and the method of expressing spots or cracks by the sponge irregularities block is the most effective means in forming natural stone patterns.

아울러 자연석의 질감을 살리기 위한 수산화 알미늄, 규석분말, 글라스 프리트의 혼합 또한 문양을 더욱 자연석에 가깝게 표현해 주는 매우 중요한 역할을 해준다.In addition, the mixture of aluminum hydroxide, silica powder and glass frit to enhance the texture of natural stone also plays a very important role in expressing the pattern closer to natural stone.

문양 및 색상층과 바탕색상층은 표면투명층 아래에 함께 용해되어 나타나므로 제품의 수명이 다할 때까지 변색되거나 벗겨지지 않아 내구성이 우수할 뿐 아니라 자연석과 구별할 수 없을 정도로 흡사한 문양과 색감을 가지므로 합성수지 제품의 품위와 상품성을 높이는데 크게 기여하게 될 것이다.Since the pattern, color layer and ground color layer are dissolved together under the surface transparent layer, they are not discolored or peeled off until the end of the product's life, so they are not only durable but also have patterns and colors that are indistinguishable from natural stones. It will greatly contribute to improving the quality and commerciality of synthetic resin products.
