Description
본 발명은 ABS수지상 무전해 도금분야에 관한 것으로, 보다 상세하게는 ABS 수지에 무전해 도금을 위한 ABS 수지 표면의 전처리 방법에 관한 것이다.The present invention relates to the field of electroless plating on ABS resins, and more particularly, to a pretreatment method of an ABS resin surface for electroless plating on ABS resins.
ABS 수지는 일반적으로 아크릴로니트릴과 부타디엔의 혼성중합체 및 스티렌과 부타디엔의 혼성중합체를 혼합(블렌드)하여 제조하는 것이 일반적이다. 플라스틱인 ABS 수지 표면에 금속박막을 코팅할 때 가장 문제가 되는 것은 ABS와 코팅된 금속박막의 접착력이다. 현재 ABS와 금속박막의 접착력 향상을 위해 주로 사용하고 있는 방법은 화학적 전처리 방법과 Ti, Cr 등의 접착력이 좋은 금속층을 버퍼층(buffer layer)으로 이용하는 방법이 사용되고 있다. ABS resins are generally prepared by mixing (blending) interpolymers of acrylonitrile and butadiene and interpolymers of styrene and butadiene. The most problematic problem when coating a metal thin film on the surface of ABS resin, which is plastic, is the adhesion between the ABS and the coated metal thin film. Currently, the methods mainly used to improve the adhesion between ABS and the metal thin film are used as a chemical pretreatment method and a method using a metal layer having good adhesion such as Ti and Cr as a buffer layer.
화학적 전처리 방법은 ABS 수지의 표면을 화학적으로 에칭하여 표면을 거칠게 하여 표면단면적을 증가시켜, 모재와 금속박막의 접착력을 향상시키는 방법으로, ABS에 코팅되는 금속박막의 접착력과 외관의 상태를 결정하는 가장 중요한 공정이다. 특히 밀착력은 에칭액의 조성과 사용조건 등에 따라서 변화한다. 에칭 액 은 H2SO4-크롬(Chrome)산 혼합액, 인산과 염소산 혼합액 등이 있으며, 현재 가장 널리 사용되는 사용되고 있는 에칭액은 H2SO4-크롬(Chrome)산 혼합액이다. 그 조성은 황산, 무수 크롬산, 물의 3성분으로 이루어져 있다. 또한 무수 크롬산 대신에 크롬산 나트륨, 크롬산 칼륨을 사용하는 경우도 있다. 전처리 시간은 에칭 액의 온도와 에칭액에 포함된 크롬산의 용해도에 따라 달라지지만, 처리온도 65℃이하, 크롬산의 용해량 5g/liter 이하에서 20~30분이다.The chemical pretreatment method is to chemically etch the surface of the ABS resin to roughen the surface to increase the surface cross-sectional area, thereby improving the adhesion between the base metal and the metal thin film, and to determine the adhesion and appearance of the metal thin film coated on the ABS. It is the most important process. In particular, the adhesion force varies depending on the composition of the etching solution, the use conditions, and the like. The etchant includes a H 2 SO 4 -chromic acid mixture, a phosphoric acid and chloric acid mixture, and the most widely used etchant is an H 2 SO 4 -chromic acid mixture. The composition consists of three components, sulfuric acid, chromic anhydride, and water. In addition, sodium chromate and potassium chromate are sometimes used instead of chromic anhydride. The pretreatment time varies depending on the temperature of the etching solution and the solubility of the chromic acid contained in the etching solution, but is 20 to 30 minutes at the treatment temperature of 65 ° C. or less and the amount of chromic acid dissolved at 5 g / liter or less.
이러한 화학적 처리 방법을 사용하면 실용적으로 충분한 금속박막의 접착력을 얻을 수 있으나, 전처리 과정에서 CrO3, HCl, H2SO4, HF 등의 고농도 폐수가 방출되는 공정이 필수적이어서 수질오염의 심각한 문제를 야기하는 결정적인 단점이 있다.Using this chemical treatment method, practically sufficient metal thin film adhesion can be obtained. However, during the pretreatment process, a high concentration of wastewater such as CrO 3 , HCl, H 2 SO 4 and HF is required to release serious problems of water pollution. There is a crucial disadvantage.
본 발명은 상기한 바와 같은 종래기술의 문제점을 해결하기 위한 것으로서, 본 발명의 목적은 ABS 수지의 전처리 공정을 환경 친화적인 방법으로 하여, ABS 수지를 70%이상 함유하는 수지제품에 환경친화적 무전해 도금을 위한 표면 전처리 방법을 제공함에 있다.The present invention is to solve the problems of the prior art as described above, an object of the present invention is to environmentally friendly electroless to a resin product containing 70% or more ABS resin by using the pre-treatment process of the ABS resin as an environmentally friendly method The present invention provides a surface pretreatment method for plating.
이러한 본 발명의 목적을 달성하기 위하여, 본 발명은 ABS 수지에 기존의 화학적 처리 대신에 발포제와 환경친화적 수용성 접착제를 처리하여 ABS 수지 표면을 매우 거칠게 하여 물리적인 체결력을 증가시키는 방법을 사용한다.In order to achieve the object of the present invention, the present invention uses a method of treating the ABS resin with a foaming agent and an environmentally friendly water-soluble adhesive instead of conventional chemical treatment to make the surface of the ABS resin very rough to increase the physical fastening force.
상기와 같은 본 발명의 목적을 달성하기 위하여, 본 발명은 ABS 수지 혹은 ABS 수지가 다량 함유된(70%이상) 피도물의 도금부위의 사출 이형제를 제거하는 단계(S1)와, 상기 피도물의 표면에 환경친화적 수용성 접착제를 도포하는 단계(S2)와, 상기 도포된 환경친화적 수용성 접착제를 70% 건조시키는 단계(S3)와, 상기 건조된 수용성 접착체 표면에 발포제를 도포하는 단계(S4)와, 상기 도포된 수용성 접착제와 발포제를 건조시키는 단계(S5)와, 적외선 열원으로 상기 도포된 발포제를 발포시키는 단계(S6)와, 그리고 상기 도포된 발포제 중 발포되지 않은 발포제를 제거하는 단계(S7)로 구성되는 무전해 도금을 위한 ABS 수지 표면 전처리 방법을 제공한다..In order to achieve the object of the present invention as described above, the present invention is a step (S1) of removing the injection release agent on the plating portion of the coating material containing a large amount of ABS resin or ABS resin (70% or more), and on the surface of the workpiece Applying an environmentally friendly water-soluble adhesive (S2), drying the applied environmentally friendly water-soluble adhesive (70%) (S3), applying a foaming agent to the dried water-soluble adhesive surface (S4), and Drying the applied water-soluble adhesive and the blowing agent (S5), foaming the applied blowing agent with an infrared heat source (S6), and removing the non-foaming blowing agent from the applied blowing agent (S7). It provides ABS resin surface pretreatment method for electroless plating.
본 발명에 의하면 ABS 수지 혹은 ABS 수지를 70%이상 함유하는 수지제품에 환경 친화적 무전해 도금을 위한 표면 처리를 할 수 있는 등의 다음과 같은 주요 효과가 있다. According to the present invention has the following main effects, such as surface treatment for environmentally friendly electroless plating on ABS resin or a resin product containing 70% or more ABS resin.
먼저, ABS 수지의 화학적인 에칭 공정을 배제하므로, 에칭, 중화공정을 완전 배제할 수 있어 작업 공정을 단순화 할 수 있으며, 특히 에칭, 중화공정에서 나오는 CrO3, H2SO4, HF 등의 특정 폐기물을 완전 배제할 수 있고 전처리 공정에 들어가는 폐수처리용수 및 수세수 사용량을 완전 배제할 수 있으며 폐수 처리 인력을 절감할 수가 있다.First of all, the chemical etching process of ABS resin is excluded, so the etching and neutralization process can be completely excluded, thus simplifying the work process, especially the specific waste such as CrO3, H2SO4, HF from etching and neutralization process. Can completely eliminate the wastewater treatment and flushing water used in the pretreatment process and reduce the wastewater treatment manpower.
이하에서는 바람직한 실시예를 통하여 본 발명을 보다 상세히 설명한다.Hereinafter, the present invention will be described in more detail with reference to preferred embodiments.
먼저 본 발명에서의 이형제 제거에는 탈지액을 사용한다. 탈지액에는 산성과 알칼리성이 있으며 알칼리성욕은 산성욕에 비교해서 탈지력이 있기 때문에 형상이 복잡한 성형품에 하고는 있지만 탈지 후에 수세가 나쁘면 에칭액을 노화시키기 때문에 산성욕이 널리 사용되고 있다. 산성욕의 산은, 황산, 염산, 인산, 초산 등의 무기산과 개미산, 삭산 등의 유기산이 고려되지만, 유기산은 에칭액에 들어가면 에칭액을 노화시키기 때문에 바람직하지 못하다. 초산은 강산화제이므로 성형품이 탈지가 되지 않고 성형품의 소지를 열화시키기 때문에 사용하여서는 안 된다. 염산은 에칭액에 들어가면 염화수소 가스가 발생하여 작업환경을 나쁘게 하기 때문에 사용하지 않는 쪽이 좋다. 결국 황산이 인산보다 좋은 것은 황산은 인산보다 코스트가 낮으며, 애칭액에 황산이 포함되어 있기 때문에 탈지후의 수세공정이 필요 없다는 것으로 황산욕이 일반적이다. 그러나 황산 만으로서는 탈지력이 없고 황산과 계면활성제를 조합하면 탈지의 효과가 있다. 계면활성제는 산에 강한 것이 양호하다. 탈지액의 관리는, 황산은 분석법에 의해서 하며, 계면활성제는 분석이 대단히 어렵기 때문에 눈으로 탈지액 중의 거품의 정도를 보고 판단한다. 그러나 조성이 아주 다르지 않는 한, 탈지에 의한 불량제품이 거의 없기 때문에 일반적으로 무시되는 경향이다. 탈지액의 투명도를 조사하여 아주 탁하여졌을 때, 이 액이 애칭액의 노화로 이어지기 때문에 갱신하는 편이 좋다. 노화액은 물론 희석하여 버린다.First, a degreasing solution is used to remove the release agent in the present invention. The degreasing solution is acidic and alkaline, and the alkaline bath is degreasable compared to the acidic bath. Therefore, although it is used for a molded product having a complicated shape, the acid bath is widely used because the etching solution is aging when the water is bad after degreasing. Acids of the acidic bath are considered inorganic acids such as sulfuric acid, hydrochloric acid, phosphoric acid and acetic acid, and organic acids such as formic acid and saxic acid. However, the organic acid is not preferable since the acid is etched into the etching solution. Acetic acid is a strong oxidizing agent and should not be used because it does not degrease the molded part and degrades its properties. It is better not to use hydrochloric acid because hydrogen chloride gas is generated when it enters the etching solution, which deteriorates the working environment. In the end, sulfuric acid is better than phosphoric acid because sulfuric acid has a lower cost than phosphoric acid and sulfuric acid bath is not necessary because desulphurizing solution contains sulfuric acid. However, sulfuric acid alone has no degreasing power, and combining sulfuric acid and a surfactant has a degreasing effect. The surfactant is preferably acid resistant. The degreasing solution is managed by sulfuric acid analysis, and the surfactant is difficult to analyze. However, unless the composition is very different, it tends to be generally ignored because there are few defective products by degreasing. When the transparency of the degreasing solution is investigated and becomes very turbid, it is better to renew the solution because this leads to aging of the nicking solution. Of course, the aging solution is diluted.
또한 본 발명에서 사용되는 수용성 접착제는 아크릴계 수지와 우레탄계 수지 성분으로 된 것을 사용할 수 있으며 수용성 에멀젼 으로 일액으로 자연건조에 의한 건조가 가능한 것을 사용하되 건조후 접착제 조성물의 성분이 알갱이로 남는 것은 사용하지 않는 것이 좋다. 상기 수용성 접착제는 일반적으로 플라스틱 표면에 도장 밀착력을 좋게 하기 위해 사용하는 프라이머를 사용할 수도 있다. 이 경우에도 프라이머의 주 성분은 아크릴계나 우레탄계로 수용성인 것을 사용하는 것이 좋다. 상기 수용성 접착제는 메탄올과 혼합하여 사용한다. 메탄올과 접착제의 부피비는 10:1 정도로 한다. 이 부피비는 사용하는 접착제나 프라이머의 종류에 따라 다를 수 있다.In addition, the water-soluble adhesive used in the present invention may be made of an acrylic resin and a urethane-based resin component, which can be dried by natural drying as a liquid solution as a water-soluble emulsion, but the components of the adhesive composition after drying do not use It is good. In general, the water-soluble adhesive may use a primer used to improve the paint adhesion to the plastic surface. In this case as well, the main component of the primer is preferably acrylic or urethane. The water-soluble adhesive is used by mixing with methanol. The volume ratio of methanol to adhesive is about 10: 1. This volume ratio may vary depending on the type of adhesive or primer used.
또한 본 발명에서의 도포된 접착제의 건조시간은 혼합된 메탄올의 양에 따라 다르며 사용한 접착제와 프라이머의 종류에 따라 다르다. 건조시 완전 건조시키지 않고 약 70% 정도로 건조시킨다.In addition, the drying time of the applied adhesive in the present invention depends on the amount of methanol mixed and the type of adhesive and primer used. Dry to about 70% without drying completely.
본 발명에서의 발포제를 도포는 피도물 표면에 금속박막과의 결착력을 주기 위한 미세 공극을 만들기 위한 것으로 발포제는 열에 의해 분해되면서 주로 질소나 이산화탄소와 같은 무해 가스가 방출되는 것으로 한다. 상기 발포제는 열에 의해 분해되므로 피도물이 열적 변형이 되지 않도록 열분해 온도가 피도물의 열변형 온도보다 낮은 것을 택하는 것이 바람직하다. 피도물에 상기 발포제를 도포하기 위해서는 발포제를 메탄올이나 증류수와 분산시킨 혼합액을 만든 후 이 발포제 혼합액에 피도물을 짧은 시간 동안 침적 시킨다. 상기 발포제와 메탄올 또는 증류수와의 혼합비는 질량비로 발포제 1에 메탄올 혹은 물을 10으로 하는 것이 바람직하다. 상기 발포제 혼합액의 메탄올 혹은 물이 건조되는데 시간이 필요하므로 처리속도를 증가시키는 목적으로는 물보다는 메탄올을 사용하는 것이 바람직하다.The application of the blowing agent in the present invention is to make fine pores for imparting a binding force to the metal thin film on the surface of the workpiece, and the blowing agent is mainly decomposed by heat to release harmless gases such as nitrogen and carbon dioxide. Since the blowing agent is decomposed by heat, it is preferable that the pyrolysis temperature is lower than the heat deformation temperature of the workpiece so that the workpiece is not thermally deformed. In order to apply the blowing agent to the coated object, a mixed solution in which the blowing agent is dispersed with methanol or distilled water is prepared, and the coated object is dipped in the blowing agent mixture for a short time. The mixing ratio of the blowing agent to methanol or distilled water is preferably 10 to methanol or water in the blowing agent 1 in a mass ratio. Since methanol or water of the blowing agent mixture is required to dry, it is preferable to use methanol rather than water for the purpose of increasing the treatment speed.
또한, 발포제를 발포시키기 위한 단계에서 사용하는 열선은 적외선 열원이나 할로겐 열기구 등을 사용할 수 있다. 상기 열원이나 열기구로 피도물의 표면에 도포된 발포제를 발포시 열원이나 열기구에 의한 온도가 피도물의 열에 의한 변형 온도보다 낮도록 해야 바람직하다.In addition, as the heating wire used in the step of foaming the blowing agent, an infrared heat source, a halogen hot air balloon, or the like can be used. When foaming agent applied to the surface of the workpiece with the heat source or hot air balloon, it is preferable that the temperature caused by the heat source or the hot air balloon be lower than the deformation temperature caused by the heat of the coated material.
이 후 피도물에 무전해 도금을 하기 위해서는 수세 후 무전해 도금 공정을 적용한다.Afterwards, in order to electrolessly plate the workpiece, an electroless plating process is applied after washing with water.
상기에서 도포된 발포제 중 발포되지 않은 발포제의 제거는 초음파조에서 처리하는 것이 바람직하다. 사용한 발포제의 종류에 따라 초음파 조에서 처리해야할 시간을 적절히 정하는 것이 바람직하다. The removal of the non-foamed foaming agent among the blowing agents applied above is preferably treated in an ultrasonic bath. It is preferable to appropriately determine the time to be treated in the ultrasonic bath according to the type of blowing agent used.
