본 발명은 도료의 샌딩은폐성 평가 장치에 관한 것으로서, 일정한 하중의 압력으로 균일한 샌딩면이 생성되어 샌딩은폐성 평가의 신뢰성이 향상되고, 빠르고 용이하게 샌딩면이 만들어져 샌딩은폐성의 평가시간이 단축됨으로써, 신규 도료의 효율적인 시험 평가 및 관리가 이루어지는 도료의 샌딩은폐성 평가 장치에 관한 것이다.The present invention relates to an apparatus for evaluating sanding concealability of a paint, wherein a uniform sanding surface is generated under a constant load pressure, thereby improving reliability of sanding concealment evaluation, and a sanding surface is quickly and easily made to reduce sanding concealment evaluation time. Thus, the present invention relates to a sanding concealment evaluation device for paints, in which efficient test evaluation and management of new paints are performed.

일반적으로 차량에는 많은 종류의 도장 재료가 사용되고, 특히 차체 부식 방지 및 외관 향상을 위해 차체를 차체용 도료로 도장한다. Generally, many kinds of paint materials are used in a vehicle, and in particular, the vehicle body is coated with a vehicle body paint to prevent corrosion of the body and to improve appearance.

또한, 차체용 도료는 차체에 직접 도장하고, 차의 수명이 다 할 때까지 차체용 도료의 기능을 유지해야 하는바, 차체 도료 개발시 다양한 평가 방법으로 차체용 도료를 평가한다.In addition, the paint for the car body should be applied directly to the car body and the function of the car body paint should be maintained until the life of the car is over. Therefore, the car body paint is evaluated by various evaluation methods when the car body paint is developed.

도장 라인에서 차체는 여러 단계로 도장이 되고, 그 과정에서 도장된 차체에 이물, 핀홀 등이 있을 때 그 부위를 고운 샌드페이퍼로 연마를 하고, 그 위에 다시 도료로 도장을 한다. In the painting line, the car body is painted in several stages. In the process, when there are foreign materials, pinholes, etc. on the car body, the parts are polished with fine sandpaper, and then painted again with paint.

이 때, 도료가 연마 자국을 은폐 시켜야 도장이 완성되었을 때 흔적이 남지 않는바, 도료의 은폐성능은 차체용 도료 개발시 중요한 평가 항목 중 하나이다. At this time, the paint should conceal the polishing marks so that no trace remains when the painting is completed. Therefore, the concealment performance of the paint is one of the important evaluation items in the development of paint for the body.

이를 도료의 샌딩은폐성이라고 하는데, 예를들어 베이스(BASE) 도료의 샌딩은폐성 평가 방법의 경우 중도까지 마감된 도장판에 라인에서 사용하는 샌드페이퍼 에 의한 일정한 하중으로 샌딩한다.This is called sanding concealment of paints. For example, in the case of the evaluation method of sanding concealment of BASE paints, sanding is applied with a constant load by sand paper used in the line on the finished plate.

그 후 샌딩된 중도 표면을 깨끗하게 세척하고, 해당 베이스 도료를 구배도장한다.The sanded midway surface is then washed clean and the base paint is gradient coated.

첨부한 도 1은 구배도장 방법의 단면도이고, 도 2는 종래 도료의 샌딩은폐성 평가방법의 과정도이다.1 is a cross-sectional view of the gradient coating method, Figure 2 is a process chart of the sanding concealment evaluation method of the conventional paint.

여기서, 구배도장은 도 1에서 도시한 바와 같이 도료(100)를 점점 두껍게 도장하는 도장방법을 말한다.Here, the gradient coating refers to a coating method for coating the paint 100 gradually thicker as shown in FIG.

이와 같이 종래 샌딩은폐성 평가 방법은 종래 도 2에서 도시한 바와 같이 우선 중도 마감된 도장판(200)을 준비하고, 규정된 샌드 페이퍼(210)를 도장판(200) 위에 놓는다.As described above, in the conventional sanding concealment evaluation method, as shown in FIG. 2, the paint plate 200 is first prepared as a middle finish, and the prescribed sand paper 210 is placed on the paint plate 200.

다음으로, 손에 의해 일정한 힘을 주어 도장판(200) 위를 아래로 샌딩하고, 샌딩된 도장판(200)을 깨끗이 세척하여, 해당 베이스로 구배도장(230)을 실시한다.Next, by applying a constant force by hand sanding down the coating plate 200, and cleans the sanded coating plate 200, and performs a gradient coating 230 to the base.

여기서, 은폐되는 곳의 베이스 도막두께를 측정 및 기입하며, 은폐되는 도막두께가 낮으면 낮을수록 샌딩은폐성이 우수한 것이다.Here, the base film thickness of the place to be concealed is measured and written, and the lower the thickness of the concealed film is, the better the sanding concealment is.

이러한 샌딩은폐성 평가에 있어서 가장 중요한 것은 균일하게 도장판(200)에 샌딩면(220)을 만드는 것이다. The most important thing in evaluating sanding concealment is to make the sanding surface 220 on the coating plate 200 uniformly.

일정한 하중으로 균일하게 샌딩을 해야 정확한 샌딩면(220)을 얻을 수 있으므로, 동일한 조건으로 샌딩을 해야 동일한 샌딩면(220)으로 정확한 상대비교를 할 수 있고, 결과에 신뢰성이 있는 것이다. Since the sanding uniformly with a constant load can be obtained accurate sanding surface 220, sanding under the same conditions can be accurate relative comparison with the same sanding surface 220, the result is reliable.

하지만, 현재는 샌딩은폐성 평가를 할 때 사람이 손으로 직접 하중을 주어 샌딩을 하기 때문에 시험할 때마다 균일한 샌딩면을 만들기가 어려운 문제점이 있다.However, at present, the sanding concealability evaluation is difficult to make a uniform sanding surface every time because the sanding is given by hand directly by the person.

이에 샌딩면의 샌딩 폭 및 깊이가 불균일하므로, 이에 따른 평가 결과는 신뢰성이 떨어질 수 밖에 없고, 시험자에 따라 샌딩면이 달라지는 문제점이 있다.Since the sanding width and depth of the sanding surface is non-uniform, the evaluation result according to this is inevitably deteriorated, there is a problem that the sanding surface is different depending on the tester.

따라서, 본 발명은 상술된 문제점을 해결하기 위해 발명된 것으로서, 샌드페이퍼가 볼트와 고무블록에 의해 고정되는 조절부와 이 조절부가 안착되도록 중앙에 관통홈이 형성되고, 하부 각 모서리에 바퀴가 형성되는 이동부로 구성됨으로써, 일정한 하중의 압력으로 균일한 샌딩면이 생성되어 샌딩은폐성 평가의 신뢰성이 향상되고, 빠르고 용이하게 샌딩면이 만들어져 샌딩은폐성의 평가시간이 단축됨으로써, 신규 도료의 효율적인 시험 평가 및 관리가 이루어지는 도료의 샌딩은폐성 평가 장치를 제공하는데 그 목적이 있다.
