본 발명은 컬러 브라운관의 알루미늄 반사막 증착용 필르밍유제 조성물에 관한 것으로, 특히 알루미늄의 반사막을 증착하기전에 도포되는 필르밍(filming) 유제의 성분중 하나인 아크릴 에멀젼(acryl emulsion) 전체에 음이온 계면활성제인 디옥틸-소듐-설포석시네이트(Dioctyl-Sodium-Sulfosuccinate)를 소량 첨가하여 용이한 알루미늄 반사막 증착으로 컬러 브라운관의 휘도(brightness)를 향상시킬 수 있도록 한 조성물에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a peeling emulsion composition for depositing an aluminum reflective film of a color CRT, particularly an anionic surfactant throughout an acrylic emulsion, which is one of the components of a filming emulsion applied before depositing a reflective film of aluminum. The present invention relates to a composition in which a small amount of phosphorus dioctyl-sodium-sulfosuccinate is added to improve brightness of color CRTs by easy aluminum reflecting film deposition.
일반적으로 컬러 브라운관의 스크린을 형성하는 방법에 있어서는 형광체 슬러리(fluorescent slurry)를 브라운관의 전방 패널 내면에 도포하여 자외선으로 노광하고 이를 온순수로 현상하여 최종 색상의 형광체를 도포한 다음 휘도의 향상을 위해 금속 반사막인 알루미늄막을 증착하게 되는 바, 알루미늄막을 증착하기전에 컬러 브라운관용의 필르밍 유제를 도포해야만 한다.In general, in the method of forming a screen of a color CRT, a fluorescent slurry is applied to the inner surface of the CRT front panel and exposed to ultraviolet rays, and then developed with warm pure water to apply a phosphor of a final color, and then to improve luminance. Since an aluminum film, which is a metal reflective film, is to be deposited, a filming agent for color CRT must be applied before the aluminum film is deposited.
필르밍 유제는 아크릴 에멀젼이 주성분으로서 그 일반식은 다음과 같다.The blooming emulsion is an acrylic emulsion whose main component is the general formula:
CH2=CX-CO-ORCH 2 = CX-CO-OR
여기서 X : 수소원자 또는 메틸기Where X is a hydrogen atom or a methyl group
R : 알킬기R: alkyl group
이러한 필르밍 유제는 주성분인 아크릴 에멀젼과 함께 유니사이즈(PVA붕산 에스테르의 별명임), 과산화수소, 콜로이달 실리카, 글리세린, 암모니아수로 구성된다.These peeling emulsions are composed of unisize (nickname of PVA boric acid ester), hydrogen peroxide, colloidal silica, glycerin, and ammonia water, together with an acrylic emulsion as a main component.
상기의 필르밍 유제를 사용하여 형광체면에 다공성(多孔性)의 막을 적정하게 형성시키고 그것에 의해 금속의 알루미늄 피막을 다공성으로 하여 베이킹 공정(Baking Process)에서 필르밍 유제의 분해가스를 금속피막의 다공성 기층으로 배출시키므로써 금속 반사막을 형성시킨다.Using the filming oil, the porous film is formed on the surface of the phosphor appropriately, and the aluminum film of metal is made porous so that the decomposition gas of the filming oil is removed from the baking process during the baking process. By discharging to the base layer, a metal reflective film is formed.
알루미늄 피막의 증착을 용이하게 하기 위한 종래의 컬러 브라운관용 필르밍 유제의 조성은 다음과 같이 이루어진다.The composition of the conventional colorant tube blooming oil for facilitating the deposition of the aluminum film is as follows.
이와 같은 필르밍 유제의 성분비율에 따라 상기에서와 같이 금속 알루미늄 피막읠 다공기층을 통해 분해 가스를 배출시키므로써 알루미늄 피막의 이동 및 부풀음 현상을 억제하고 따라서 양호한 금속 반사막을 형성시켜 컬러 브라운관의 휘도를 증가시킬 수 있게 되는 것이다.According to the composition ratio of the filming emulsion, the decomposition gas is discharged through the metal aluminum film 알루미늄 porous layer as described above to suppress the movement and swelling of the aluminum film, thereby forming a good metal reflecting film, thereby improving the brightness of the color CRT. You can increase it.
그러나 종래의 알루미늄 금속 박막증착에 의하면 통상 필르밍 유제의 온도 24℃, 패널(4) 내부의 형광면 스크린 온도 35℃에서 제 1 도에 도시된 바와 같이 필르밍 유제(2)가 매끈하고 균일한 알루미늄 반사막(1)을 형광체면에 형성시키지 못하므로 결국 금속 박막층인 알루미늄 반사막(1)의 증착 상태는 표면이 불연속적이고 매끈하지 못한 거칠은 면의 알루미늄 반사막을 갖게 된다.However, according to the conventional aluminum metal thin film deposition, the film is usually smooth and uniform as shown in FIG. 1 at a temperature of 24 ° C. of the peeling emulsion and a fluorescent screen screen temperature of 35 ° C. inside the panel 4. Since the reflective film 1 cannot be formed on the phosphor surface, the deposition state of the aluminum reflective film 1, which is a metal thin film layer, eventually has a roughly aluminum reflective film whose surface is discontinuous and not smooth.
이는 제 2 도에서와 같이 형광체면에 대한 필르밍액의 접촉각(θ1)이 높은 둔각을 갖는 상태로서 즉, 형광체면에 대한 필르밍액의 표면장력이 크기 때문에 필르밍액의 형광체면에 대한 도포시 유동성이 불량하므로 매끈하고 단단한 연속적인 도포막 형성이 불가능한 것이며, 결론적으로 이는 반사효율이 기대에 미치지 못하여 브라운관의 휘도 향상에 제한적인 주된 요소로서 존재함을 부인할 수 없는 것이다.This is a state in which the contact angle (θ 1 ) of the peeling liquid with respect to the phosphor surface has a high obtuse angle as shown in FIG. 2, that is, the fluidity during application of the peeling liquid to the phosphor surface due to the large surface tension of the peeling liquid with respect to the phosphor surface. Because of this defect, it is impossible to form a smooth and hard continuous coating film, and consequently, it cannot be denied that the reflection efficiency is lower than expected and is present as a major factor limiting the brightness of the CRT.
본 발명에서는 브라운관의 휘도향상에 크게 기여할 수 있는 필르밍 유제를 제공하고자 하는 것인바, 특징적으로 필르밍 유제의 조성물 중에서 아크릴 에멀젼에 대하여 음이온 계면활성제를 소량 첨가하여 반응시킨 것으로서, 이를 보다 구체적으로 설명하면 다음과 같다.The present invention is to provide a filming emulsion that can greatly contribute to the improvement of the brightness of the CRT, characterized in that the reaction by adding a small amount of anionic surfactant to the acrylic emulsion in the composition of the filming emulsion, it will be described in more detail Is as follows.
형광체의 슬러리를 제 3 도와 같이 브라운관의 패널(4) 내면에 도포하여 자외선으로 노광하고 온순수로 현상하여 최종적인 색상의 형광체를 도포한 다음, 형광체 위로 다음과 같이 조성된 중간 필름막인 컬러 브라운관의 필르밍 유제막을 형성한다.A slurry of the phosphor was applied to the inner surface of the panel 4 of the CRT as shown in FIG. 3, exposed with ultraviolet light, developed with warm pure water, and then a phosphor of the final color was applied. A film emulsion film is formed.
상기의 필르밍 유제 조성물중에서 아크릴 에멀젼 전체 부피에 대하여 음이온 계면활성제인 디옥틸, 소듐, 설포석시네이트(Dioctyl-Sodium-Sulfosuccinate)를 0.1-0.5중량% 첨가하여서 된 필르밍 유제를 조성하여 이 필르밍 유제 화합물을 형광체면(3)에 도포하면 형광체면(3)에 다공성의 피막이 형성된다.In the peeling emulsion composition, 0.1-0.5% by weight of anionic surfactants dioctyl, sodium and sulfosuccinate (Dioctyl-Sodium-Sulfosuccinate) were added to the total volume of the acrylic emulsion to form a peeling emulsion. When the reming emulsion compound is applied to the phosphor surface 3, a porous film is formed on the phosphor surface 3.
이 피막이 필르밍 유제(2a)인 것이며 알루미늄 반사막(1a)의 증착을 용이하게 하기 위한 중간 기재로서 작용하게 된다.This film is a filming agent 2a and serves as an intermediate substrate for facilitating the deposition of the aluminum reflective film 1a.
이후 형광체면(3)에 알루미늄의 금속피막을 증착하면 필르밍 유제(2a)에 의해 금속피막인 알루미늄 반사막(1a)이 다공성의 피막으로 되고 베이킹 공정에서 필르밍 유제(2a)의 분해가스가 알루미늄 반사막(1a)의 다공성 기층을 통하여 배출된다.Subsequently, when the metal film of aluminum is deposited on the phosphor surface 3, the aluminum reflecting film 1a, which is a metal film, becomes a porous film by the filming emulsion 2a, and the decomposition gas of the filming emulsion 2a is made of aluminum in the baking process. It is discharged through the porous base layer of the reflecting film 1a.
상기에서 필르밍 유제의 온도는 24℃, 패널(4) 내부의 형광면 스크린 온도는 35℃에서 필르밍 유제층 위에 매끈하고 균일한 연속적인 알루미늄층을 얻을 수 있게 되는 것이다.In the above, the film temperature of the filming emulsion is 24 ° C., and the screen surface of the fluorescent screen inside the panel 4 is 35 ° C., thereby obtaining a smooth and uniform continuous aluminum layer on the film film.
이는 필르밍 유제의 조성물중 아크릴 에멀젼에 첨가한 음이온 계면활성제의 기여에 의해 이룩되는 것으로서, 즉 제 4 도에서 보는 바와 같이 상기의 계면활성제는 종래 제 2 도에서와 같은 형광체면에 대한 필르밍 유제의 접촉각(θ2)을 예각의 범위로 대폭 낮추므로써(필르밍 유제의 표면장력 값이 작아짐) 필르밍 유제의 유동성(흐름성)이 양호해져 필르밍막 형성시 매끈하고 단단한 연속적인 도막형성을 가능하게 하고 따라서 매끈하고 균일한 알루미늄 반사막(1a)은 물론 그 반사막이 단단하고 연속적인 평활면을 얻을 수 있는 것이다.This is achieved by the contribution of the anionic surfactant added to the acrylic emulsion in the composition of the filming emulsion, i.e., as shown in FIG. 4, the above-mentioned surfactant is a filming agent for the surface of the phosphor as in FIG. By greatly reducing the contact angle (θ 2 ) in the acute angle range (the surface tension value of the filming agent is reduced), the fluidity (flowability) of the filming agent is improved, so that a smooth and solid continuous film can be formed when forming the film. Therefore, the smooth and uniform aluminum reflecting film 1a as well as the reflecting film can obtain a hard and continuous smooth surface.
또한 필르밍 유제의 양호한 유동성으로 알루미늄 반사막(1a)의 다공성 기층을 통한 필르밍 유제(2a)의 분해가스 배출이 용이하고 원활하게 이루어지므로 조직이 치밀하고 단단한 연속적인 평활면을 제공받을 수 있게 되는 것이다.In addition, due to the good fluidity of the film emulsion, the decomposition gas of the film emulsion 2a is easily and smoothly discharged through the porous base layer of the aluminum reflective film 1a, so that the tissue can be provided with a dense and rigid continuous smooth surface. will be.
이와 같이 하여서 된 양질의 알루미늄 반사막에 의해 전자총의 캐소드로부터 방출되는 전자빔의 반사효율을 증가시켜 궁극적으로 휘도를 대폭 증가시킬 수 있게 되는 바, TV는 물론 각종 모니터의 스크린에 폭넓게 사용될 수 있는 산업상 그 기여도가 큰 발명인 것이다.The high-quality aluminum reflecting film made in this way increases the reflection efficiency of the electron beam emitted from the cathode of the electron gun and ultimately significantly increases the brightness, which can be widely used in TVs and various monitor screens. It is an invention with a large contribution.
