본발명은 반사형 액정표시판이나 비데오스크리인 둥에 사용되는 무지향성(無指向性) 윤빼기(艶消 ,delustering) 처리한 알루미늄박의 제조방법에 관한 것이다.The present invention relates to a method for producing an aluminum foil delustering treatment used in a reflective liquid crystal display panel or a video screen.

알루미늄박을 겹쳐서 압연하면, 이렇게 압연한으로써 합쳐진 면(이하 "합친면"이라함)이 윤빼기 처리되는것이 알려져 있다.It is known that when aluminum foil is rolled up and rolled up, the surfaces joined by this rolling (hereinafter referred to as "blended surface") are subjected to a polishing process.

이 알루미늄박은 상기와 같은 용도에 사용되고 있으나, 압연방향에 있어서 반사광에 지향성(指向性)이 있기 때문에, 보는 각도에 따라 선명함이 다르다는 결점이 있다.Although this aluminum foil is used for the above uses, since it has directivity to reflected light in a rolling direction, there exists a fault that sharpness differs according to a viewing angle.

그것은 다중 압연의 합친면에 생긴 미세한 홈이 압연방향에 대해 거의 직각방향, 즉 알루미늄박의 폭방향으로 뻗어 있기 때문이다.This is because the fine grooves formed on the mating surfaces of the multiple rollings extend in a direction substantially perpendicular to the rolling direction, that is, in the width direction of the aluminum foil.

그러나 그와 같은 홈이 어떤 메카니즘에 의해 발생되는가 라고 하는 점에 관해서는 유감스러우나 현재까지도 분명한 것은 알려지지 않고 있다.However, it is a pity that such a groove is caused by a mechanism, but it is not known to this day.

일반적으로는 알루미늄박이 서로 접촉된 합쳐진 면에 존재하는 결정입자의 각각이 압연방향으로 끌려서 자유변형된 결과, 랜덤으로 경사하기 때문에 이와 같은 홈이 형성되는 것으로 추정되고 있다.In general, it is estimated that such grooves are formed because each of the crystal grains present in the combined surface in which the aluminum foil is in contact with each other is pulled in the rolling direction and freely deformed, and thus is inclined at random.

본 발명은 상기와 같은 결점을 해소하고, 지향성이 작은 윤빼기 처리된 알루미늄박의 제조방법을 제공하는 것을 목적으로 하고 있다.An object of the present invention is to solve the above-described drawbacks and to provide a method for producing a foil-treated aluminum foil having low directivity.

상기의 목적을 달성하기 위해, 본 발명에 있어서는 알루미늄박의 압연방향에 대해 45。 이하의 각도로 뻗어 있는 다수의 미세한 스크래치를 형성하고, 이 스크래치가 형성된 면을 겹쳐서(합친면으로 하여) 압연을 행하여, 무지향성 윤빼기 처리한 알루미늄박을 제조한 것이다.In order to achieve the above object, in the present invention, a plurality of fine scratches are formed which extend at an angle of 45 DEG or less with respect to the rolling direction of the aluminum foil, and the rolling is carried out by superimposing the surfaces on which the scratches are formed (to be a combined surface). In order to produce the aluminum foil subjected to non-directional polishing.

상기와 같이, 미리 압연방향에 대해 45˚ 이하의 각도로 스크래치를 형성하면 두면, 겹치기 압연에 의해 생기는 미세한 홈과 서로 교차하게 되어, 반사광의 지향성이 없어져서 무지향성에 가까운 반사면이 얻어진다.As described above, if scratches are formed at an angle of 45 degrees or less with respect to the rolling direction in advance, they intersect with the fine grooves generated by the overlap rolling, and the directivity of the reflected light is lost, thereby obtaining a reflective surface close to non-directional.

제1도에 도시한 바와같이 압연을 행한 알루미늄박 웨브(A)를 지지로울러(1)로 지지하면서 송출하고, 웨이브(A)의 상면에 회전브러시(2)를 맞닿게해서 웨브(A)의 이송방향 또는 역방향으로 회전시킨다.As shown in FIG. 1, the rolled aluminum foil web A is supported while being supported by the support roller 1, and the rotary brush 2 is brought into contact with the upper surface of the wave A to provide the Rotate in the feed or reverse direction.

이 회전 브러시(2)를 놋쇠나 스테인레스의 와이어(wire)가 심어져 있기 때문에 얻어진 웨브 (A)의 표면에는 미세한 할퀸상처 즉, 스크래치가 형성되어 있다.Since the rotating brush 2 is made of brass or stainless wire, fine scratch marks, that is, scratches, are formed on the surface of the web A obtained.

제2도에 도시한 바와같이 상기 지지로울러(1)를 대신해서 슬라이드 테이블(3)을 사용하여도 좋다.As shown in FIG. 2, a slide table 3 may be used in place of the support roller 1.

또, 제3도에 도시한 바와같이 상기 회전브러시(2)를 대신해서 미세한 사립(砂粒)을 외면에 부착시킨 무단벨트(4), 소위 벨트식 사포연삭기를 사용하여도 좋고 혹은, 제4도에 도시한 바와같이 외주에 고무로 된 숫돌중의 수지제 숫돌을 설치한 숫돌로울러(5)를 사용하여도 좋다.In addition, as shown in FIG. 3, an endless belt 4, a belt-type sandpaper grinder, in which fine grains are attached to the outer surface instead of the rotary brush 2, may be used. As shown in the figure, a whetstone roller 5 in which a resin grindstone of rubber grindstone is provided on the outer circumference may be used.

이들의 회전브러시(2), 무단벨트(4), 숫돌로울러(5)의 웨브(A)에 대한 맞닿는각도는 제5도에 도시한 바와같이 얻어진 웨브(A')에 거의 압연방향으로 또는 압연방향에 대해 45˚ 이하의 각도로 뻗어 있는 스크래치(6)가 형성되도록 한다.The contact angles of the rotary brushes 2, the endless belt 4, and the whetstone roller 5 with respect to the web A are almost rolled or rolled on the web A 'obtained as shown in FIG. The scratches 6 are formed to extend at an angle of 45 degrees or less with respect to the direction.

예컨대 회전브러시(2)의 경우에는 제6도에 도시한 바와같이 브러시(2)의 회전축이 웨브(A)의 이송방향 (화살표)과 직교하든지, 혹은 쇄선으로 표시한 바와 같이 그 직교축과 45˚이내의 범위로 경사지게 배치하면 좋다.For example, in the case of the rotating brush 2, as shown in FIG. 6, the axis of rotation of the brush 2 is orthogonal to the conveying direction (arrow) of the web A, or as indicated by the dashed line and the axis 45 It may be arranged inclined to within the range.

또 어느 경우도 브러시가 축방향으로 자유롭게 이동하면서 회전하여도 지장은 없다.In any case, there is no problem even if the brush rotates while moving freely in the axial direction.

압연방향으로 스크래치를 형성항 웨브(A')의 처리면을 합친면으로 하여, 제7도에 도시한 바와같이 로울 (7,7)로 겹치기 압연으로 행하면, 제8도에 도시한 바와같이 미세한 홈(8)이 압연방향에 대해 거의 직각방향으로 형성된 웨브(A")가 얻어진다.When the surface of the web A 'forming the scratches in the rolling direction is combined, the surface is rolled into rolls 7 and 7 as shown in FIG. A web A 'is formed in which the groove 8 is formed in a direction substantially perpendicular to the rolling direction.

또, 겹치기 압연은 2매 겹치기에 한정하지 않고, 3매 이상이라도 좋고, 또 대향하는 합친면의 양면에 스크래치(6)가 형성되어 있지 않아도 한쪽면에 형성되어 있으면 합친면의 다른쪽에 그것이 전사되어서 거의 제8도에 가까운 요철면을 가지는 웨브가 얻어진다.In addition, the overlap rolling is not limited to two stacks, but may be three or more sheets. If the scratches 6 are formed on one side even when the scratches 6 are not formed on both sides of the opposing joining surfaces, they are transferred to the other side of the joining surfaces. A web having an uneven surface close to 8 is obtained.

또, 압연방향에 대해 45˚로 스크래치를 형성한 웨브(A')의 처리면을 스크래치가 서로 직교하도록 겹쳐서 겹치기 압연을 행하면, 제9도에 도시한 바와같은 압연방향에 대해 45˚의 경사를 이루면서 서로 직교하는 스크래치와 압연방향으로 직교하는 홈(8)이 형성된 웨브(A")가 얻어진다. 얻어진 윤빼기 처리한 알루미늄박의 두께는 특히 제한되어져야 하는 것이 아니지만, 통상 약10μ 내지 300μ정도이다.In addition, when the surface of the web A 'having a scratch formed at 45 ° with respect to the rolling direction is overlapped with each other so that the scratches are orthogonal to each other, overlap rolling is performed to incline 45 ° with respect to the rolling direction as shown in FIG. In this way, a web A 'provided with scratches orthogonal to each other and grooves 8 orthogonal to the rolling direction are formed. The thickness of the obtained aluminum foil subjected to bleeding is not particularly limited, but is usually about 10 μm to 300 μm.

액정반사판의 경우, 휘는 성질을 갖게하기 위해 두께 약 10μ 내지 50μ의 얇은 알루미늄박으로 하는 것이 적당하다.In the case of a liquid crystal reflector, it is suitable to use a thin aluminum foil having a thickness of about 10 µm to 50 µm in order to have a bending property.

폴리에틸렌 테레프탈레이트 필름을 이면보강층으로서 접착제를 통해서 부착한 적층체로 하는 것이 좋다. 이하에 실험예와 비교예를 든다.It is good to set it as the laminated body which adhered the polyethylene terephthalate film through an adhesive as a back surface reinforcement layer. An experimental example and a comparative example are given to the following.

[실시예 1]Example 1

두께 300μ의 알루미늄박(JIS IN 30(H))의 표면에 지름 0.1㎜의 스테인레스와이어를 심어 설치한 회전브러시를 압연방향에 대해 45˚경사시켜서 맞닿게하고, 브러싱처리를 행하였다.A rotating brush in which a stainless wire having a diameter of 0.1 mm was planted on the surface of an aluminum foil (JIS IN 30 (H)) having a thickness of 300 mu was inclined to be brought into contact with the rolling direction by being inclined at 45 DEG, and brushed.

이 알루미늄박 2매를 스크래치가 서로 직교하도록 처리면을 맞추어 겹치고, 입하율 40%로 냉간압연을 행하였다.Two aluminum foils were piled up so that scratches were orthogonal to each other, and they were cold-rolled at a loading rate of 40%.

얻어진 알루미늄박의 겹쳐맞춘면은 대단히 흰 외관을 나타내었다.The overlapping surface of the obtained aluminum foil showed very white appearance.

또한 백색광의 입사방향을 다르게해서 반사특성을 측정하였다.In addition, the reflection characteristics were measured by changing the incident direction of the white light.

결과를 제1표에 표시하였다.The results are shown in the first table.

[실시예 2]Example 2

두께 300μ의 알루미늄합금박(JIS 3003)의 표면에 회전브러시의 와이어를 놋쇠로 하고, 브러시의 회전축을 압연방향과 직각으로 한 것외에는 실험예 1과 같은 처리를 행하였다.The same process as Experimental example 1 was performed except that the wire of the rotating brush was brazed on the surface of the aluminum alloy foil (JIS 3003) having a thickness of 300 µ, and the rotating shaft of the brush was perpendicular to the rolling direction.

얻어진 알루미늄박의 외관은 실험예 1의 것과 매우 유사하였다.The appearance of the obtained aluminum foil was very similar to that of Experimental Example 1.

이것을 실험예 1과 같은 검사를 하였다.This test was carried out as in Experimental Example 1.

결과를 표 1에 표시하였다.The results are shown in Table 1.

[비교예][Comparative Example]

최종압연이 2매 합친 압연인 통상의 제박공정으로 두께 180μ의 알루미늄박 (IN 30(H))을 얻고, 그 반사 특성을 실험예 1과 같이 측정하였다.The aluminum foil (IN30 (H)) of 180 micrometers in thickness was obtained by the normal milling process of final rolling combining two sheets, and the reflection characteristic was measured like Experimental example 1. As shown in FIG.

결과를 제 1표에 표시하였다.The results are shown in the first table.

측정은 고니오포토미터(Goniophotometer)(무라까미 시끼사이겐큐쇼, 모델 GP-200)를 사용하고, 샘플경사각 5˚, 백색광 입사각 30˚, 수광 각 -15˚ 내지 75˚로 행하였다.The measurement was carried out using a Goniophotometer (Murakami Shikisaigen Kyusho, Model GP-200) at a sample tilt angle of 5 °, white light incident angle of 30 °, and a light receiving angle of -15 ° to 75 °.

제1표에서 명백한 바와 같이 실험예 1과 2의 샘플은 백색광의 압사방향이 압연방향과 평행인 경우와 직각인 경우, 양자의 반사특성이 대단히 유사하고 무지향에 가까운 반사면인 것을 알 수 있다.As is clear from Table 1, it can be seen that the samples of Experimental Examples 1 and 2 are reflective surfaces that are very similar in their reflection characteristics and are almost non-directional, when the incidence direction of white light is parallel to the rolling direction.

또 비교예의 것은 명백하게 지향성을 가지고 있다.In addition, the comparative example clearly has directivity.

본 발명에 의하면, 이상과 같이 미리 알루미늄박의 표면에 미세한 스크래치를 형성하여 두고, 이 면을 겹쳐서 겹치기 압연을 행하기 때문에 겹치기 압연에 의한 미세한 홈이 상기 스크래치와 서로 교차해서 형성되어, 무지향에 가까운 반사특성을 가지는 윤빼기 처리한 면이 얻어지고, 따라서 액정반사판이나 반사스크리인에 알맞은 알루미늄박을 얻을 수가 있는 효과가 있다.According to the present invention, fine scratches are formed on the surface of the aluminum foil in advance as described above, and the overlapping rolling is performed by overlapping the surfaces, so that fine grooves formed by the overlap rolling are formed to cross the scratches, and thus are almost unoriented. It is possible to obtain an aluminum foil having a reflecting property, and thus obtain an aluminum foil suitable for a liquid crystal reflector or a reflective screen.

물론 네임플레이트, 화장판, 에지장식재, 왕관등에 알맞게 사용된다.Of course, it is used for nameplates, decorative plates, edge decoration, crowns, etc.
