Description

도로방음벽용 도로미화형 방음판{Soundproofed plate for sound absorbing walls of a road}Soundproofed plate for sound absorbing walls of a road}

본 발명은 도로방음벽재로 유용한 금속제 방음판에 관한 것이며, 특히 타발한 흡음공 언저리의 부식방지와 주변경관과 어울리게 미감을 드높인 도로방음벽용 방음판에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal soundproofing plate useful as a road soundproofing wall material, and more particularly to a soundproofing plate for a road soundproofing wall which has enhanced aesthetics to match the surrounding environment and corrosion prevention of a blown sound absorber.

민가를 지나는 고속도로변, 고속화도로변, 자동차 전용도로변에는 자동차의 주행소음피해로부터 주민을 보호하기 위하여 도로방음벽을 설치하는 사례가 있다.이러한 도로방음벽 중에는 규격화한 금속제 패널로 된 것도 있다. 금속제 패널은 부식에 약한 일반 금속제와, 일반 금속제에 비해 내식성을 가진 알루미늄제 등 두 종류가 있다.There are cases where road noise barriers are installed on highways, highways and private roads that pass through private homes to protect residents from driving noise damage from cars. Some of these road noise barriers are made of standardized metal panels. There are two types of metal panels: general metal, which is weak to corrosion, and aluminum, which has corrosion resistance compared to general metal.

문제는 일반 금속제 방음판에 있다. 일반 금속제 방음판은 알루미늄제 방음판에 비해 가격이 저렴한 이점을 가진 반면 부식에 약하기 때문에 수명이 짧다. 방음판으로서의 수명이 짧다보니 교체가 잦아 경시적으로 는 알루미늄제 방음판 보다도 더 비경제적이다. 부식을 억제하기 위하여 표면에 도장을 실시하지만, 도장층의 수명에도 한계는 있기 마련이기 때문에 항구적이지 못하다.The problem lies in the sound insulation of ordinary metal. In general, the metal sound insulation board has the advantage of being inexpensive compared to the aluminum sound insulation board, but it is short in life because it is weak to corrosion. As the lifespan as a soundproof board is short, it is frequently replaced, making it more economical than aluminum soundproof boards over time. Although coating is performed on the surface in order to suppress corrosion, it is not permanent because the life of the coating layer is limited.

특히 타발가공에 의해 형성된 흡음공의 언저리는 도료가 묻지 않는 경향이 있어서 이 부분부터 부식이 일어나 방음판의 전면으로 번지게 되는데, 어느 부위든 일단 부식이 발생하면 녹물이 표면으로 흘러내려서 흉물스럽게 보이므로 도로변의 미관을 해친다.In particular, the sound absorbing hole formed by punching tends to have no paint on it, so that corrosion occurs from this part and spreads to the front side of the soundproof board. Once corrosion occurs in any part, green water flows to the surface and looks vicious. It hurts the beauty of the roadside.

이런 경우, 그때마다 일일이 보수하는 것은 현실적으로 무리다. 도로방음벽이 부지기수여서 적기에 인력을 동원하기가 여의치 않고 유지보수장비도 부족한데다 예산확보 문제 등 여러 가지 제약이 따르기 때문이다.In this case, it is practically impossible to repair each time. Due to the lack of road noise barriers, it is difficult to mobilize manpower in a timely manner, lack of maintenance equipment, and various constraints such as budgeting problems.

일반 금속제 방음판에 비해 어느 면에서는 우위에 있는 알루미늄제 방음판 중에도 소재 자체에 불순물이 개입된 알루미늄판으로 제작된 것에서도 부식으로 인한 폐해가 발견된다. 도색 강판제의 경우 타발한 흡음공의 언저리는 나금속이므로 부식에 대해서는 속수무책이다.The damage caused by corrosion is also found in the aluminum soundproof plate, which is superior to the general metal soundproof plate, in the case of the aluminum plate in which impurities are introduced into the material itself. In the case of painted steel, the edge of the blown sound-absorbing hole is bare metal, so it is irrelevant to corrosion.

이러한 점에서, 부식에 약한 도로방음벽용 방음판의 부식방지에 대한 획기적인 대책이 마련되어야 하겠다.In this regard, the groundbreaking measures to prevent the corrosion of the soundproof board for road soundproof walls that are susceptible to corrosion should be prepared.

한편, 방음판의 재질이 어떠하든 지금까지는 방음판을 구성하는 소재의 금속색 일변도였다. 금속색은 보편적으로 회색으로 너무 단조롭고, 도로변 경관과 어울리지 않는다. 특히 알루미늄은 햇빛을 반사하여 눈부심이 심해 운전자의 운전시야를 방해하는 경우도 있으므로 때론 위험하다. 이 점을 고려하여 방음판의 표면을 금속색 이외의 도료로 도장하는 방안이 제시되었다.On the other hand, whatever the material of a soundproof board, until now, it was the metallic one side of the material which comprises a soundproof board. Metallic colors are generally too monotonous in grey, and do not match the roadside landscape. Aluminum is particularly dangerous because it reflects sunlight and can cause severe glare and interfere with the driver's field of view. In consideration of this, a method of coating the surface of the soundproof panel with a paint other than metallic color has been proposed.

그러나, 그 도색이란 것이 단색 위주여서 미관개선효과가 미흡하고,However, since the painting is monochromatic, the effect of improving aesthetics is insufficient.

서화를 그려 넣은 방음벽도 있긴 하지만 인위적인 분위기가 어색하기 짝이 없다.There are soundproof walls with calligraphy paintings, but the artificial atmosphere is awkward.

이러한 점에서, 방음판의 의장성에 대한 대책도 함께 강구할 필요가 있다.In this regard, it is also necessary to take measures against the design of the sound insulation board.

본 발명은 타발한 흡음공 언저리의 부식을 효과적으로 방지할 수 있고, 또한 도로변의 경관에 어울려 미간개선에 기여할 수 있는 도로방음벽용 방음판을 제공하기 위한 것이다.The present invention is to provide a soundproofing board for road soundproof walls that can effectively prevent the corrosion of the blown sound absorbing edges, and also contribute to the improvement of the beauty of the roadside.

본 발명의 이 같은 과제는, 폴리에스터 분말도료를 사용하여 고온 분위기 하에서 도로방음벽용 금속제 방음판의 표면을 분체도장하고, 분체도장층의 표면에 나무결 무늬 전사지를 대고 고온 전사하여 부식에 강한 내력을 발휘하면서 도로변의 나무숲과 쉽게 조화되는 나무결 무늬로 도로방음벽의 미관이 돋보이게 한 도로방음벽용 방음판에 의해 달성할 수 있다.This object of the present invention, the powder coating of the surface of the metal soundproofing plate for road sound insulation walls using a polyester powder coating, and by applying a wood grain transfer paper on the surface of the powder coating layer to a high temperature transfer to exhibit a high corrosion resistance In addition, it can be achieved by the soundproof board for road soundproof walls, which makes the aesthetics of the road soundproof walls stand out with the wood grain pattern that easily harmonizes with the wood forest on the roadside.

도 1에서, 일반 금속제 또는 알루미늄제 도로용 방음판(1)의 표면에 분체도장층(2)을 형성한다. 분체도장층(2)의 주원료는 폴리에스터 분말이다. 폴리에스터는 인열강도, 내후성, 내화학성, 내광성, 금속에 대한 접착강도, 도색성 등이 우수하여 바탕도장층 재료로 더없이 훌륭하다.In Fig. 1, the powder coating layer 2 is formed on the surface of the general soundproof plate 1 made of metal or aluminum. The main raw material of the powder coating layer 2 is polyester powder. Polyester has excellent tear strength, weather resistance, chemical resistance, light resistance, adhesion strength to metal, paintability, etc. and is excellent as a base coating layer material.

분체도장층(2)은 200℃ 내외의 고온분위기 하에서 실시한다. 분체도장 분위기가 200℃를 훨씬 상회하면 응고시간이 더뎌서 도장능률이 낮고, 변색과 소실의 우려가 있다. 반면에 분체도장 분위기가 200℃를 훨씬 밑돌면 금속 표면에 대한 전개성이 저하되어 도장층의 두께가 불균일하고 접착성도 부실해질 우려가 있다.The powder coating layer 2 is carried out in a high temperature atmosphere of about 200 ℃. When the powder coating atmosphere is much higher than 200 ° C., the solidification time is slow and the coating efficiency is low, and there is a fear of discoloration and disappearance. On the other hand, when the powder coating atmosphere is well below 200 ° C., the developability on the metal surface is lowered, resulting in uneven thickness of the coating layer and poor adhesion.

도 2에서, 분체도장층(2)은 타발로 형성된 흡음공(3)의 언저리(4)로도 잘 흘러들어 완벽한 기초도장층을 형성할 수 있으므로 흡음공(3)의 언저리(4)에 대한 불완전한 기초도장 또는 도장으로 인한 폐해, 즉 언저리(4)의 조기 부식방지에 대단한 효과가 있다. 분체도장층(2)은 대체로 다른 색상의 도료나 무늬를 부여하기에 적합한 흰색계통이다.In Fig. 2, the powder coating layer 2 can flow into the edge 4 of the sound-absorbing hole 3 formed by punching well to form a perfect base coating layer, so that the sound-absorbing hole 3 is incomplete with the edge 4 of the sound-absorbing hole 3. There is a great effect on the damage caused by the basic coating or painting, ie early corrosion of the edge (4). The powder coating layer 2 is generally a white system suitable for giving paints or patterns of different colors.

다시 도 1에서, 상기 분체도장층(2)의 표면에 전사무늬(5)를 입힌다. 전자무늬(5)는 그러한 무늬가 인쇄된 전사지를 방음판(1)의 분체도장층(2)에 대고 10 분 정도 가열(200℃ 내외)한 후 필름을 제거하는 방법으로 부여한다.In FIG. 1, the transfer pattern 5 is coated on the surface of the powder coating layer 2. The electronic pattern 5 is applied by a method of removing the film after heating (about 200 ° C.) for about 10 minutes to the powder coating layer 2 of the soundproof plate 1 on which the pattern is printed.

전사무늬(5)는 소나무, 참나무 등의 껍질, 나무결에 그에 맞는 색을 가미한 것이다. 이러한 전사무늬(5)는 도로변의 산야에 서식하는 숲과 썩 잘 어울리는 무늬로, 거부감이 적고 보기에도 좋다.The transfer pattern (5) is a bark of pine, oak, etc., to add color to match the wood texture. Such a transfer pattern 5 is a pattern that goes very well with forests inhabiting the hillsides on the roadside, and there is little rejection and is good to see.

상기 도로방음벽용 방음판은 기초도장으로 일반 상온 도장층과는 달리 고온에서 폴리에스터 분말도료로 분체도장함으로서 기초도장층의 내구성이 향상되고, 타발한 흡음공의 언저리까지도 분체도장에 의한 부식방지효과가 나타난다.The soundproofing board for road soundproof walls is a basic coating, and unlike ordinary normal temperature coating layers, the powder coating with polyester powder coating at high temperature improves the durability of the basic coating layer, and prevents corrosion by the powder coating even on the edge of the sound absorbing hole. appear.

분체도장층 위에 전사법으로 입힌 나무결무늬, 나무껍질무늬는 도로변 산야의 조경과 한껏 어울려 도로변 미관개선에 이바지한다.The wood grain pattern and bark pattern coated on the powder coating layer by the method of transcript are combined with the landscape of Sanya on the roadside to contribute to improving the aesthetics of the roadside.
