굴삭기, 지게차, 적하기(loader) 등 중장비에 사용되고 있는 기존 도료는 고형분이 제한적이고 유기 용제의 사용량이 많아 생산성 저하 및 작업자의 건강을 해지는 등 문제점이 제기되고 있다. 특히 기존 도료는 납, 카드뮴, 바륨, 크롬 등 중금속 함량이 높아 환경문제를 유발시켜 선진국에서는 일정함량 이하의 중금속을 함유하는 도료만을 사용하도록 유도하고 있고, 일부 국가에서는 이를 환경규제 항목으로 적용하여 실시하고 있어 수출을 위해서는 반드시 중금속을 함유하지 아니한 형태의 도료 개발이 필수적이다. 현재 사용중인 일반 도료는 중금속 함량이 수만에서 수십만 ppm에 이르고 있다.Existing paints used in heavy equipment, such as excavators, forklifts, and loaders, have a limited solid content and have a large amount of organic solvents, causing problems such as lower productivity and healthier workers. In particular, existing paints have a high content of heavy metals such as lead, cadmium, barium, and chromium, causing environmental problems. In advanced countries, only paints containing heavy metals below a certain content are used, and some countries apply them as environmental regulations. In order to export, it is essential to develop paints that do not contain heavy metals. General paints currently in use contain heavy metals ranging from tens of thousands to hundreds of thousands of ppm.

본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로서, 본 발명의 목적은 고형분을 최대한 증가시켜 휘발성 유기화합물(volatile organic compound; VOC) 의 사용량을 최소화시키고 중금속 함량을 극소화시킨 환경친화 도료를 제공하는 것이다.The present invention has been made to solve the above problems, an object of the present invention to minimize the amount of volatile organic compounds (VOC) by increasing the solid content as possible to provide an environmentally friendly paint that minimizes the heavy metal content It is.

상기와 같은 본 발명의 목적은, 아크릴 단량체들을 공중합한 아크릴 에스터 폴리올 수지 (acrylic ester polyol resin) 에 대하여, 경화제로서 이소시아네이트 (isocyanate), 안료로서 카본 블랙/ 탈크/ 방청 안료, 첨가제로서 분산제, 침강 방지제, 용제로서 방향성 용제(aromatic solvent)/ 아세테이트/ 케톤으로 구성되는 우레탄계 도료에 의해 달성된다.The object of the present invention as described above, for the acrylic ester polyol resin copolymerized acrylic monomers, isocyanate as a curing agent, carbon black / talc / rust preventive pigment as a pigment, dispersant as an additive, anti-settling agent And a urethane-based paint composed of an aromatic solvent / acetate / ketone as a solvent.

본 발명은 피도체의 하도 위에 가교밀도를 높여 밀착도가 개선된 수지와 중금속이 최소화된 안료를 사용하여 스프레이로 분사하여 도착하고 건조하여 도막을 형성시키는 기술을 특징으로 한다.The present invention is characterized by a technique of increasing the crosslinking density on the undercoat of the subject by spraying with a resin using a resin with improved adhesion and a minimized heavy metal, and drying to form a coating film.

본 발명의 그밖의 목적, 특정한 장점 및 신규한 특징들은 이하의 상세한 설명과 바람직한 실시예로부터 더욱 분명해질 것이다.Other objects, specific advantages and novel features of the invention will become more apparent from the following detailed description and the preferred embodiments.

이하 본 발명에 따른 우레탄계 도료의 구성에 대하여 설명하기로 한다.Hereinafter, the structure of the urethane paint according to the present invention will be described.

본 발명은 아크릴 에스터 폴리올 수지, 경화제, 안료, 첨가제, 용제 등으로 구성된다. 수지는 도막의 성능을 결정하는 근간이며 본 발명에서 사용된 수지는 수산기를 가진 특정 아크릴 단량체들을 공중합한 아크릴 에스터 폴리올 수지로서 내후성이 우수하다. 경화제로서는 이소시아네이트를 사용하였고, 안료는 카본 블랙, 탈크, 방청 안료로 구성되며, 첨가제는 분산제와 침강방지제로 구성되며, 용제는 방향성 용제, 아세테이트, 케톤으로 구성된다.This invention consists of acrylic ester polyol resin, a hardening | curing agent, a pigment, an additive, a solvent, etc. The resin is the basis for determining the performance of the coating film, and the resin used in the present invention is an acrylic ester polyol resin copolymerized with specific acrylic monomers having hydroxyl groups, and has excellent weather resistance. Isocyanate was used as the curing agent, and the pigment is composed of carbon black, talc, and rust preventive pigment, the additive is composed of dispersant and antisettling agent, and the solvent is composed of aromatic solvent, acetate, and ketone.

각 성분의 중량비는 아크릴 에스터 폴리올 수지 (acrylic ester polyolresin) 20~25 중량부, 이소시아네이트 (isocyanate) 5~10 중량부, 카본 블랙 (carbon black) 1.5~2 중량부, 탈크 (talc) 20~25 중량부, 방청안료 5~10 중량부, 분산제 0.5 중량부 이상, 침강방지제 0.6 중량부 이상, 방향성 용제 (aromatic solvent) 15~25 중량부, 아세테이트 (acetate) 10~14 중량부, 케톤 (ketone) 3~7 중량부로 구성된다.The weight ratio of each component is 20 to 25 parts by weight of acrylic ester polyolresin, 5 to 10 parts by weight of isocyanate, 1.5 to 2 parts by weight of carbon black, and 20 to 25 parts by weight of talc. Parts, 5-10 parts by weight of rust preventive pigment, 0.5 parts by weight or more of dispersant, 0.6 parts by weight or more of anti-settling agent, 15-25 parts by weight of aromatic solvent, 10-14 parts by weight of acetate, ketone 3 And 7 parts by weight.

이하 상기와 같은 구성을 갖는 본 발명의 우레탄계 도료의 작용 및 실시예에 대하여 설명하기로 한다Hereinafter will be described the operation and examples of the urethane-based paint of the present invention having the configuration as described above.

본 조성물에 있어 상기 아크릴 에스터 폴리올 수지 (acrylic ester polyol resin) 는 20% 이하가 되면 밀착성이 저하되고, 25% 이상이 되면 광택도가 저하된다. 우레탄계 도료의 경화제 이소시아네이트 (isocyanate) 는 상기 아크릴 에스터 포욜 수지의 당량비로써 사용량을 결정하였다.In this composition, when the acrylic ester polyol resin is 20% or less, the adhesiveness is lowered, and when it is 25% or more, the glossiness is lowered. The curing agent isocyanate of the urethane-based paint was determined as the equivalent ratio of the acrylic ester foam resin.

안료(pigment)는 도막의 색상과 방청성을 좌우하는 도막의 주요소이며 본 발명에서 카본 블랙(carbon black)은 도막의 색상을 부여하는 착색 흑색안료이며 1.5~2 중량부가 본 발명의 도료에서 최적의 색상을 확보할 수 있는 함량이다. 저흡유량의 탈크(talc)는 20~25 중량부 범위가 은폐력을 확보하면서도 고형분을 증가시킬 수 있는 최적 함량이다. 방청안료는 피도체의 내부식성 (corrosion resistance)향상을 위해 첨가하며 5~10 중량부 사용시 최적의 성능을 나타낸다. 또한 상기의 안료들은 인체 유해성을 최소화하기 위해 중금속을 함유하지 아니한 형태를 개발하여 적용한 것이 특징이다.Pigment (pigment) is a major element of the coating film that determines the color and rust resistance of the coating film in the present invention carbon black (carbon black) is a coloring black pigment imparting the color of the coating film and 1.5 to 2 parts by weight of the optimal color in the paint of the present invention It is the content that can be secured. Low oil absorption talc (talc) is in the range of 20 to 25 parts by weight is the optimum content that can increase the solid content while securing hiding power. Anti-rust pigment is added to improve the corrosion resistance of the object and shows the best performance when used 5 to 10 parts by weight. In addition, the pigments are characterized by developing and applying a form that does not contain heavy metals in order to minimize human hazards.

첨가제는 도막형성의 보조 성분으로 도료 및 도막 성능을 보강하여 준다. 분산제는 이온성에 의해 입자간 반발력을 부여하여 안료 입자을 안정화시켜 재응집하지 않도록 한다. 0.4 중량부 이하가 되면 착색도, 도막외관이 저하하고 응집이 발생하여 사용이 곤란하다. 침강방지제는 도료 혼합이나 도장시의 전단력에 의해 점성이 떨어지거나 겉보기 점도가 상승하여 침강되는 것을 막아주며 이러한 저장 안정성을 갖기 위해서는 0.6 중량부 이상은 첨가하여야 한다.Additives reinforce paint and film performance as an auxiliary component in film formation. Dispersants impart interparticle repulsion by ionicity to stabilize pigment particles and prevent them from reaggregating. When it is 0.4 weight part or less, coloring degree and coating film appearance will fall, aggregation will arise, and it will be difficult to use. The sedimentation inhibitor prevents sedimentation due to viscosity loss or apparent viscosity increase due to the mixing force or the shearing force at the time of painting. To have such storage stability, 0.6 parts by weight or more should be added.

용제는 수지를 녹이고 도료제조 및 도장을 돕는 성분이며 도료의 유동성, 도장 작업성에 영향을 미친다. 통상적으로 도장라인(coating line) 조건을 감안하여 설정하는 것이 보통이다. 방향성 용제(aromatic solvent)는 수지에 대한 용해력은 적으나 희석제 및 휘발속도 조정의 기능을 수행하기 위해 14 중량부 이하이면 휘발 속도가 지나쳐 도장 작업을 수행할 수 없고, 19중량부 이상이면 희석기능이 떨어진다. 아세테이트(acetate)는 수지에 대한 용해력은 보통이나 고비점 용제로서 도막의 초기 건조를 늦추기 위해 사용하며 백화방지, 도막 평활화, 스프레이(spray) 작업성 향상을 위해 첨가하고 동절기, 하절기시의 온도를 고려하여 10~15 중량부 범위내에서 사용한다.Solvent dissolves resin and helps paint production and painting, affecting the fluidity and paintability of paint. Usually, setting is made in consideration of coating line conditions. Aromatic solvent has little solvent dissolving ability to resin, but if it is 14 parts by weight or less to carry out the function of diluent and volatilization speed adjustment, the volatilization speed can not be performed. Falls. Acetate is usually a high boiling point solvent, but it is used to slow the initial drying of coatings. It is added to prevent whitening, coating smoothing, and spray workability, and takes into account winter and summer temperatures. It is used within the range of 10 to 15 parts by weight.
