Description
본 발명은 플라스틱, 비철금속 등과 부착성이 우수하며 흡음성 또한 우수한 친환경 도료 조성물에 관한 것으로, 보다 상세하게는 자동차 부품, 전기 부품, 일반 가정용품 등의 제품의 도장에 사용될 수 있는 부착성 및 흡음성이 우수한 친환경 도료 조성물 및 이를 사용하여 형성된 도막을 갖는 제품에 관한 것이다.
The present invention relates to an eco-friendly paint composition having excellent adhesion to plastics, nonferrous metals, etc., and also excellent sound absorption, and more particularly, excellent adhesion and sound absorption properties which can be used for painting products such as automobile parts, electrical parts, and general household products. It relates to an environmentally friendly paint composition and a product having a coating film formed using the same.
현재 가전제품, 모바일 폰 등에 적용되는 소재로는 플라스틱이 주종을 이루고 있으며, 플라스틱 소재의 응용은 이 같은 제품들을 포함하여 자동차 부품, 전기 부품, 일반 가정용품에 이르기까지 적용 범위가 다양해지고 있다.Currently, plastic is mainly used as a material applied to home appliances and mobile phones, and the application of plastic materials is diversified to include automotive parts, electric parts, and general household goods.
이처럼 다양한 제품에 플라스틱을 적용하는 이유는 플라스틱은 가볍고 열에 의한 성형이 용이하여 다양한 모양으로 제조할 수 있으며, 그 자체로도 내구성 및 충격성이 강한 장점이 있기 때문이다.The reason why plastics are applied to various products is that plastics can be manufactured in various shapes because they are light and easy to be formed by heat, and they have advantages in terms of durability and impact resistance.
통상적으로 이러한 플라스틱 제품을 소재의 오염을 방지하고, 용제에 대한 저항성 등 내화학성을 높이며, 우수한 심미감을 부여하기 위하여 도장 과정을 거치게 된다.Typically, these plastic products are subjected to a coating process to prevent contamination of the material, to increase chemical resistance such as resistance to solvents, and to provide excellent aesthetics.
한편, 도료는 피코팅체의 재질, 또는 표면의 상태 등의 다양성에 부합하도록 개발되고 있다. 예를 들면, 피코팅체는 구조 재료로 널리 이용되는 철금속으로부터 마그네슘, 알루미늄, 티탄 또는 이들의 합금 등을 포함하는 비철금속으로 대체되고 있다. 마그네슘, 알루미늄, 티탄 등의 금속 원자들은 일반 철재에 비하여 매끄러운 표면에 의하여 소지 부착이 매우 불량한 난부착성 기재이므로, 일반적인 도료의 수지로서 이용되는 아크릴멜라민 수지, 아크릴우레탄 수지, 아크릴 실리콘 수지 등은 비철금속에 부착이 용이하지 않다.On the other hand, the paint has been developed to meet a variety of materials, such as the material to be coated, or the surface state. For example, the to-be-coated body has been replaced by nonferrous metals including magnesium, aluminum, titanium or alloys thereof from ferrous metals widely used as structural materials. Since metal atoms such as magnesium, aluminum, and titanium are poorly adhered substrates having poor surface adhesion due to a smooth surface compared to general steel, acryl melamine resin, acrylic urethane resin, and acrylic silicone resin used as resins of general paints are nonferrous metals. Not easy to attach
또한 일반적인 도료들은 다량의 휘발성 유기용제를 사용하고 있으며, 휘발성 유기용제는 인간을 포함한 생물체에 해롭거나 독성을 미칠 수 있다.In addition, general paints use a large amount of volatile organic solvents, and volatile organic solvents may be harmful or toxic to organisms including humans.
본 발명자들은 자동차 부품, 전기 부품, 일반 가정용품 등을 제조하는데 사용되는 플라스틱 재질, 비철금속 재질 등에 부착성이 우수하면서도 휘발성 유기용제를 사용하지 않은 친환경적인 도료에 대해 예의 연구를 거듭하였고, 그 결과 플라스틱뿐만 아니라 비철금속과의 부착성도 우수하며 흡음성이 우수한 친환경적인 도료를 개발하여 본 발명을 완성하기에 이르렀다.

Hereinafter, a preferred embodiment will be described in order to facilitate understanding of the present invention. It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined by the appended claims.
[실시예][Example]
하기 표 1에 기재된 성분이 포함된 도료를 사용하여 도막을 제조하였다. 도료로는 유레카 HPRS123(유림특수화학(주))을 사용하였으며, 표 2에 기재된 도장 조건에 따라 상기 도료를 물과 혼합하여 15 %의 희석률로 배합한 후 소지처리된 기재 상에 이를 3 회 도포하여 500 ㎛ 두께의 도막을 형성하였다. 도막의 형성과정에서 도료 조성물의 점도는 25 ℃에서 4000 CPS이었고, 스프레이건 구경은 19 mm이였고, 공기 압경은 4000 PSI이였으며, 건조 온도 및 시간은 하기 표 2와 같다.
The coating film was manufactured using the paint containing the component of Table 1 below. As a paint, Eureka HPRS123 (Yurim Special Chemical Co., Ltd.) was used, and the paint was mixed with water according to the coating conditions shown in Table 2. After blending at a dilution rate of 3%, The coating was performed once to form a 500 μm thick coating film. In the course of forming the coating film, the coating composition had a viscosity of 4000 CPS at 25 ° C., a spray gun diameter of 19 mm, an air pressure of 4000 PSI, and drying temperatures and times as shown in Table 2 below.
성능 평가Performance evaluation
상기 실시예에 따라 제조된 본 발명의 도막의 성능을 다음과 같은 항목에 대해 평가하였다.The performance of the coating film of the present invention prepared according to the above Example was evaluated for the following items.
1) 외관1) Appearance
육안으로 판정하여 변색, 부풀음, 크랙 등이 없는지 평가하였고, 평가 결과, 변색, 부풀음, 크랙이 나타나지 않았다.
It was visually judged that there was no discoloration, swelling, cracks, and the like. As a result of the evaluation, discoloration, swelling, and cracks did not appear.
2) 부착력2) adhesion
칼날로 가로 1mm x 세로 1mm 간격으로 11개씩 선을 그어 100개의 바둑눈을 도막 깊이로 형성하고 스카치 테이프(3M #610)를 기포 발생 없이 부착한 후 90° 각도로 신속히 잡아 당김을 5회 연속 실시하였다. 이때 각 바둑눈의 박리 여부를 관찰하여 면적의 1/5 이상 박리된 바둑눈이 있으면 "박리", 그렇지 않은 경우 "합격"으로 평가하였다. 평가 결과 박리 현상이 나타나지 않았다.
Draw 11 lines at intervals of 1mm x 1mm with a knife blade to form 100 goggles with a film depth, attach Scotch tape (3M # 610) without bubbles, and then quickly pull it out at 90 ° angles for 5 consecutive times. It was. At this time, the presence or absence of each goggle eye was observed, and if there was more than 1/5 of the area of the goggle eyes, "peel", otherwise evaluated as "passed". The peeling phenomenon did not appear as a result of evaluation.
3) 3) 흡음성Sound absorption
ASTM C 423-90a에 따라 NRC(Noise Reduction Coefficient)를 측정한 결과 0.75의 우수한 흡음성을 나타내었다. As a result of measuring Noise Reduction Coefficient (NRC) according to ASTM C 423-90a, it showed excellent sound absorption of 0.75.
