상기 금속이온 착색공정(S30)은 소정의 색상을 가지는 금속이온 착색안료를 상기 가공석재(11)의 표면에 초음파 분사하여 착색하여 주는 공정이다.The metal ion coloring step (S30) is a step of coloring a metal ion colored pigment having a predetermined color by ultrasonic wave spraying onto the surface of the processed stone (11).

상기 착색공정(S30)에서 사용되는 본 발명에 따른 금속이온 착색안료는 다음과 같은 조성물로 구성된다.The metal ion colored pigment according to the present invention used in the coloring step (S30) is composed of the following composition.

먼저, 적색의 착색안료 조성물은 수산화철(Fe(OH)2) 20∼30중량부, 황산철(Ⅲ)(Fe2(SO4)3) 10∼15중량부, 나이트로벤젠(C6H5NO2) 2∼3중량부, 암모늄-철백반((NH4)Fe(SO4)2ㅇ12H2O) 2∼3중량부, 음이온계면활성제(Anionic Surfactant) 1∼2중량부, 증류수(H2O) 47∼65중량부로 구성된다.First, the pigment composition of the red iron hydroxide (Fe (OH) 2) 20~30 parts by weight of ferrous sulfate (Ⅲ) (Fe 2 (SO 4) 3) 10~15 parts by weight of benzene (C 6 H 5-nitro NO 2) 2~3 parts by weight, ammonium-iron alum ((NH 4) Fe (SO 4) 2 o 12H 2 o) 2~3 parts by weight of an anionic surfactant (anionic surfactant) 1~2 parts by weight of distilled water ( H 2 O) of 47 to 65 parts by weight.

또한 청색의 착색안료 조성물은, 황산철 7수화물(FeSO4ㅇ7H2O) 30∼40중량부, 헥사사이아노철(II)산칼륨(K4[Fe(CN)6]) 7∼8중량부, 크롬산납(PbCrO4) 또는 이크롬산납 3∼5중량부, 암모늄-철백반 2∼3중량부, 음이온 계면활성제 1∼2중량부, 증류수 42∼57중량부로 구성된다.In addition, the color pigment composition of the blue color, iron sulfate heptahydrate (FeSO 4 o 7H 2 O) 30~40 parts by weight of hexamethylene cyano iron (II) potassium (K 4 [Fe (CN) 6]) 7~8 wt. 3 to 5 parts by weight of lead chromate (PbCrO 4 ) or lead acetate, 2 to 3 parts by weight of an ammonium-iron alloy, 1 to 2 parts by weight of an anionic surfactant and 42 to 57 parts by weight of distilled water.

또한 흑갈색의 착색안료 조성물은, 황산코발트(CO2(SO4)3·18H2O) 30∼40중량부, 황산망간(MnSO4ㅇ(nH2O)) 10∼15중량부, 암모늄-철백반 2∼3중량부, 음이온 계면활성제 1∼2중량부, 증류수 40∼57중량부로 구성된다.In addition, dark brown-colored pigment composition of the sulfate, cobalt (CO 2 (SO 4) 3 · 18H 2 O) 30~40 parts by weight, of manganese sulfate (MnSO 4 o (nH 2 O)) 10~15 parts by weight, ammonium-iron 2 to 3 parts by weight of alum, 1 to 2 parts by weight of an anionic surfactant, and 40 to 57 parts by weight of distilled water.

이와 같이 구성되는 소정의 색상을 갖는 착색안료를 가공석재(11)에 도포하게 되는 데, 도 2c와 같이 컨베이어(40) 상에 착색도포장치(60)가 설치된다.The coloring pigment having the predetermined color thus formed is applied to the processed stone 11, and the colored coating device 60 is installed on the conveyor 40 as shown in FIG. 2C.

상기 착색도포장치(60)의 내부에는 분사노즐부(62)가 설치되고, 상기 분사노즐부(62)에는 외부의 착색안료 공급부(61)와 연결되는 구조를 가지게 된다.A jetting nozzle unit 62 is installed in the color coating device 60 and connected to an external coloring pigment supply unit 61 in the jetting nozzle unit 62.

따라서 상기 착색안료공급부(61)로부터 착색안료가 공급되면 상기 분사노즐부(62)를 통해 안료가 분사되어 가공석재(11)의 표면에 도포되어진다.Therefore, when the color pigment is supplied from the colored pigment supply unit 61, the pigment is sprayed through the jet nozzle unit 62 and applied to the surface of the processed stone 11.

이때 상기 분사되는 착색안료는 가공석재(11)의 표면은 물론 가공석재(11)의 미세기공을 통해 내부까지 스며들게 된다.At this time, the color pigment to be sprayed is impregnated to the inside through the fine pores of the processed stone 11 as well as the surface of the processed stone 11.

본 발명에 따르자면 상기 분사노즐부(12)에는 초음파진동수단을 더 설치하도록 구성된다. 이와 같은 초음파진동수단은 분사노즐부(12)를 통해 분사되는 착색안료를 더욱 미립화시켜 상기 가공석재(11)의 표면은 물론 내부 침투력을 높여주어 착색을 보다 완벽하게 수행하도록 하여준다.According to the present invention, the injection nozzle unit 12 is further provided with an ultrasonic vibration means. The ultrasonic vibrating means makes the coloring pigment injected through the injection nozzle 12 more finely, thereby enhancing the internal penetration power as well as the surface of the processed stone 11 to more completely perform the coloring.

상기 제2마이크로웨이브 건조공정(S40)은 상기 착색공정(S30)이 완료된 가공석재(11)를 마이크로웨이브을 조사하여 2차 건조하여 주는 과정이다.The second microwave drying step (S40) is a process of secondarily drying the processed stone material (11) after the coloring step (S30) is completed by irradiating microwaves.

상기 제1마이크로웨이브 건조공정(S20)은 도 2d와 같이 컨베이어(40) 상에 마이크로웨이브 건조장치(70)가 설치된다.In the first microwave drying step S20, a microwave drying apparatus 70 is installed on the conveyor 40 as shown in FIG. 2d.

상기 마이크로웨이브 건조장치(70)의 내부에는 마이크로웨이브 발진부(71)가 형성되어 마이크로웨이브를 착색 완료된 가공석재(11)로 조사한다.In the microwave drying apparatus 70, a microwave oscillating unit 71 is formed to irradiate the microwave with the colored stones 11 that have been colored.

따라서 상기 가공석재(11)는 안정된 건조가 이루어진다.Therefore, the processed stone 11 is stably dried.

통상, 종래의 기술은 착색공정 후, 건조 시 열풍건조나 열선건조를 수행하였는데, 이러한 가열 건조방식은 화강석인 가공석재를 직접 가열함으로써 열적 균열과 강도저하 현상이 일어나는 문제점이 있었다.Generally, in the conventional art, after the coloring step, drying with hot air or drying with hot air was performed. However, in such a heating and drying method, there is a problem that thermal cracking and strength deterioration are caused by directly heating the processed stone as granite.

본 발명에 따른 마이크로웨이브 건조는 가공석재(11) 내부로부터 건조가 수행되어 외부로 진행하는 건조방식으로 균열이 없고 강도저하가 발생되지 않는 것이 특징이다.The microwave drying according to the present invention is characterized in that drying is performed from inside of the processed stone 11, and there is no crack and no decrease in strength due to the drying method advancing to the outside.

상기 코팅공정(S50)은 상기 건조공정(S40)이 완료된 가공석재(11)에 소정의 코팅액을 도포하여 탈색을 방지하고 표면 손상을 방지하는 공정이다.The coating step S50 is a step of applying a predetermined coating solution to the processed stone material 11 after the drying step S40 is completed to prevent discoloration and prevent surface damage.

상기 코팅공정(S50)은 상기 건조공정(S40)을 통해 건조된 가공석재(11)의 벌어진 표면 공극을 메우고 동시에 공극 틈새의 탈색을 방지하며, 외부의 극한 상황을 극복하기 위해 소정의 코팅제로 표면을 코팅하여 주는 것이다.The coating step S50 is a step of filling the surface voids of the processed stone 11 dried through the drying step S40 and preventing the discoloration of the gap between the pores, .

이러한 코팅처리는 가공석재(11) 표면상의 방습 발수 및 외부오염을 방지하는 효과를 부여하게 된다.Such a coating treatment gives an effect of preventing moisture and water repellency on the surface of the processed stone 11 and external contamination.

본 발명에 따르자면 상기 코팅액 조성물은 칼륨 메칠실리콘(Potassium Methylsilicone) 20∼30중량부, 폴리소베이트80(Polysorbate 80) 5∼10 중량부, 증류수 60∼75중량부로 구성된다.According to the present invention, the coating liquid composition comprises 20 to 30 parts by weight of potassium methylsilicone, 5 to 10 parts by weight of Polysorbate 80 and 60 to 75 parts by weight of distilled water.

또한 본 발명 코팅고정(S50)은 도 2e에서와 같이 컨베이어(40) 상에 코팅장치(80)가 설치된다.The coating fixation (S50) of the present invention is provided with a coating apparatus 80 on the conveyor 40 as shown in FIG. 2E.

상기 코팅장치(80)의 내부에는 분사노즐부(82)가 설치되고, 상기 분사노즐부(82)에는 외부의 코팅액 공급부(81)와 연결되는 구조를 가지게 된다.The spraying nozzle unit 82 is installed in the coating apparatus 80 and connected to an external coating liquid supply unit 81 in the spraying nozzle unit 82.

따라서 상기 코팅액공급부(81)로부터 코팅액이 공급되면 상기 분사노즐부(82)를 통해 코팅액이 분사되어 가공석재(11)의 표면에 도포되어진다.Therefore, when the coating liquid is supplied from the coating liquid supply unit 81, the coating liquid is sprayed through the spray nozzle unit 82 and applied to the surface of the processed stone 11.

이때 상기 분사되는 코팅액은 가공석재(11)의 표면은 물론 가공석재(11)의 미세기공을 통해 내부까지 스며들게 된다.At this time, the sprayed liquid is impregnated to the inside through the fine pores of the processed stone 11 as well as the surface of the processed stone 11.

이와 같이 코팅공정이 완료되면 가공석재(11)의 표면 광택을 위한 연마공정을 거쳐 제품을 완성하게 된다.After the coating process is finished, the product is finished through the polishing process for polishing the surface of the processed stone 11.
