본 고안은 측면에서 입사된 광선에 대하여도 우수한 재귀반사성을 발휘시키는 재귀반사성을 향상시킨 포지에 관한 것이다.The present invention relates to a forge having an improved retroreflective property that exhibits excellent retroreflective property even with respect to a light incident from the side.
재귀반사성 이라고 함은 입사된 광선이 같은 각다, 같은 방향으로 반사하는 성질을 말하는 바, 이것은 야간보행자나 작업자 등이 재귀반사성 포지로 된 의복을 착용하였을 때 자동차의 전조등으로부터 발사된 광선을 운전자의 방향(즉 전조등 방향)으로 다시 반사되게 하여서 원거리에서도 운전자가 식별할 수 있도록 하여 교통사고를 미연에 방지토록 하는데 있다.Retroreflective refers to the property that the incident light beams are reflected in the same direction at the same angle. This means that when a pedestrian or worker wears clothes with retroreflective forge, the light emitted from the headlights of the vehicle is directed to the driver. It is reflected back to the headlight so that the driver can identify it from a long distance to prevent traffic accidents.
종래의 재귀반사성 포지는 직, 편물로 된 기포에 아크릴이나 폴리우레탄 수지로 된 접착제를 코팅하고 그 위에 알루미늄 플레이트(Aluminium Flake)를 수지와 혼합시킨 반사액을 얇게 코팅하여 평면 상태의 반사층을 형성한 다음 그 위에 다시 유리나 투명플라스틱으로 된 비즈(Beads)를 접착수지와 혼합하여 코팅한 것과, 알루미늄 플레이크를 혼합한 접착수지를 기포에 포팅하고 그 위에 비즈를 살포하여 접착시킨 것이 있었다.Conventional retroreflective forge is coated with an acrylic or polyurethane resin adhesive on a bubble made of woven or knitted fabric, and then a thin coating of a reflector mixed with an aluminum plate and a resin is formed thereon to form a reflective layer in a planar state. Then, the glass or transparent plastic beads (Beads) were mixed with the adhesive resin and coated, and the adhesive resin mixed with aluminum flakes was ported to the air bubbles, and the beads were sprayed onto the adhesive.
그러나 상기의 것들은 평면상의 알루미늄 플레이크에 구형(球形)의 비즈가 하나의 점접에서 점접촉되어 있으므로 사각(斜角)에서 입사된 광선에 대하여는 제4도에서 표시된 바와 같이 재귀반사성이 불량한 단점이 있었다.However, since the spherical beads are in point contact with the flat aluminum flake at one point of contact, the retroreflectivity is poor with respect to the light incident from the square as shown in FIG.
이와같은 문제점을 보완한 것으로서 비즈의 하반부를 알루미늄 증착하여 반사면을 형성시킨 것이 있으나 이것은 비즈자체를 부분적으로 알루미늄 증착시키는데 따르는 기술적 곤난성과 특수장치를 요하는 문제점 때문에 범용성(汎用性)이 없는 결점이 있었다.As a supplement to this problem, the lower half of the beads is deposited by aluminum to form a reflective surface, but this is because of the technical difficulties of partially depositing the beads themselves and a problem that requires a special device. there was.
본 고안은 상기한 바와 같은 선행기술의 문제점을 해결한 것으로서 예시도면에 의하여 상세히 설명하면 아래와 같다.The present invention solves the problems of the prior art as described above in detail by way of example drawings as follows.
기포(1)의 표면에 저융점 포화폴리에스텔 접착층(2)을 형성시키고 그 위에 알루미늄 플레이크(3)를 투명성 접착제와 함께 코팅하여 알루미늄 플레이크(3)가 반구형의 곡면형태가 되게하며 통상의 비즈(4)를 투명성 접착제층(5)을 사이로 하여 반구형의 알루미늄 플레이크(3)에 면접촉되게 코팅하여서 된 것이다.A low melting saturated polyester adhesive layer 2 is formed on the surface of the bubble 1 and the aluminum flakes 3 are coated thereon with a transparent adhesive so that the aluminum flakes 3 have a hemispherical curved shape. 4) is made by surface-contacting the hemispherical aluminum flake 3 with the transparent adhesive layer 5 therebetween.
본 고안에서 알루미늄 플레이크(3)는 타원형태의 것이 좋으며, 특히 장측 a가 20-100μm, 단축 b가 10-50μm이고, 두께 1-5μm의 것이 반구형의 곡면형태로 구성시키는데 매우 적합하였다.In the present invention, the aluminum flakes 3 are preferably oval, and in particular, the long side a is 20-100 μm, the short axis b is 10-50 μm, and the one having a thickness of 1-5 μm is very suitable for forming a hemispherical curved shape.
본 고안은 보다 구체적으로 설명하면 다음과 같다.The present invention is described in more detail as follows.
제6도에 도시된 바와 같은 중간제품을 표면온도가 130℃-160℃인 상,하 2개의 롤이 2-10kg/cm2의 압력으로 맞물려 회전하는 가열 압착장치에 통과시키면 상,하 두 롤러의 닢포지션(Nip position)을 통과하는 순간 저융점 포화폴리에스텔 접착층(2)이 연화 용융되면서 비즈(4)가 알루미늄 플레이크(3)를 눌르게 되어 평면구조를 가지고 있던 알루미늄 플레이크(3)가 비즈(4)를 감싸주는 곡면형태로 바뀌면서 냉각고화되어서 제1도에 도시된 바와 같은 구조를 가지게 되는 것이다.Figure 6 of the intermediate product to a surface temperature of 130 ℃ -160 ℃ as shown in, and when the two rolls are passed through a hot-pressing device which rotates in engagement with a pressure of 2-10kg / cm 2, and two rollers As the low melting point saturated polyester adhesive layer 2 softened and melted as it passed through the NIP position of the bead, the beads 4 pressed the aluminum flakes 3 so that the aluminum flakes 3, which had a flat structure, were beads. (4) is converted into a curved shape surrounding the cooling will be solidified to have a structure as shown in FIG.
본 고안 포지를 제조함에 있어서 제6도의 저융점포화 폴리에스텔 접착층(2)의 두께(H)와 비즈(4)의 직경(D)과의 비(H/D)의 값이 1-1.5로 함이 좋으며, 비즈(4)와 평면반사층(3) 사이에 있는 접착제층(5)의 간격 h는 2μm이하로 하는 것이 좋다.In producing the present invention, the value of the ratio (H / D) of the thickness (H) of the low melting point saturated polyester adhesive layer (2) of FIG. 6 to the diameter (D) of the beads (4) is 1-1.5. The spacing h of the adhesive layer 5 between the beads 4 and the planar reflection layer 3 is preferably 2 μm or less.
본 발명은 비즈(4)의 매몰부분이 반구형이 곡면구조를 가지는 알루미늄 플레이크(3)와 면접촉 되어서 반구형의 반사층을 가지게 되기 때문에 제2도에 도시한 바와 같이 사각(斜角)에서 입사된 광선을 다시 입사방향으로 반사시키게 되므로 어떤 방향에서 입사된 광선에 대하여도 우수한 재귀반사성을 발휘하게 된다.In the present invention, since the buried portion of the beads 4 is in surface contact with the aluminum flakes 3 having a hemispherical curved structure to have a hemispherical reflective layer, the light beams incident from the squares as shown in FIG. Since the light is reflected back to the incident direction, it exhibits excellent retroreflectivity with respect to the light incident from any direction.
