Description
발명의 분야Field of invention
본 발명은 폴리우레탄을 착색하기 위하여 사용되는 착색제 조성물에 관한 것이다. 보다 구체적으로 본 발명은 폴리우레탄을 착색하기 위하여 사용되는 액상의 착색제 조성물로서, 액상이기 때문에 사용하기 편리하고, 안료 입자가 폴리올과 이소시아네이트의 고분자 중간에서 반응하여 원하는 색상을 얻을 수 있는 반응성 착색제 조성물에 관한 것이다. 본 발명은 또한 폴리우레탄을 착색하기 위한 액상의 반응성 착색제 조성물을 제조하기 위한 방법도 포함한다.The present invention relates to colorant compositions used to color polyurethanes. More specifically, the present invention is a liquid colorant composition used to color polyurethane, which is convenient to use because it is a liquid, and to a reactive colorant composition in which pigment particles react in the middle of a polymer of a polyol and an isocyanate to obtain a desired color. It is about. The invention also includes a method for preparing a liquid reactive colorant composition for coloring a polyurethane.
발명의 배경Background of the Invention
폴리우레탄을 착색하기 위한 반응성 토너(toner)는 이제까지 스폰지와 같은 폴리우레탄을 착색하기 위하여 널리 사용되고 있다. 이러한 폴리우레탄 착색제 조성물은 이제까지 국내에서 개발되지 못하고, 외국으로부터 전량을 수입하여 오고 있는 실정이다.Reactive toners for coloring polyurethanes have been widely used for coloring polyurethanes such as sponges until now. Such a polyurethane colorant composition has not been developed in Korea so far, and has been imported from a foreign country in its entirety.
폴리우레탄을 착색하기 위해서는 폴리우레탄을 제조하기 위한 원료수지에 착색제 조성물을 혼합하여 폴리우레탄이 발포되면서 착색된 폴리우레탄이 생산된다. 폴리우레탄을 착색하는데 있어서 가장 큰 문제점은 폴리우레탄을 원하는 색상으로 착색할 수 없다는 것이다. 예를 들어, 폴리우레탄을 검정색으로 착색하고자 하는 경우에 원하는 색상, 즉 명도와 채도를 얻을 수 없고, 또한 균일하지 못한 색상을 나타내어 항상 불량품을 생산하는 문제점이 제기되어 왔다.In order to color the polyurethane, a colored polyurethane is produced as the polyurethane is foamed by mixing the colorant composition with a raw material resin for producing the polyurethane. The biggest problem in coloring polyurethane is that it cannot be colored in the desired color. For example, when the polyurethane is to be colored in black, a problem has been raised that a desired color, that is, brightness and saturation cannot be obtained, and a non-uniform color is always produced to produce a defective product.
외국의 폴리우레탄 착색제 조성물을 제조하는 회사들은 그 조성물에 대한 영업비밀을 보유하고는 우리 나라에 기술이전을 하지 않는 등 대외적으로도 많은 어려움이 존재하였다. 또한 이 착색제 조성물은 다량 소모되는 것이 아니기 때문에 대기업에 의하여 연구개발이 행해지지도 않고 중소기업에 의하여 연구개발이 미미하게 행해져 왔었다.Companies that manufacture foreign polyurethane colorant compositions have had a lot of difficulties externally, such as not having a technology transfer to our country after having a trade secret for the composition. In addition, since the colorant composition is not consumed in large quantities, research and development has not been conducted by large companies, and research and development has been conducted by small and medium companies.
본 발명자는 폴리우레탄 착색제 조성물의 개발에 몰두하여 최근 몇 년 동안의 연구노력 끝에 외국제품보다 품질과 성능이 우수한 본 발명의 폴리우레탄 착색제 조성물을 개발하기에 이른 것이다.After devoting to the development of the polyurethane colorant composition, the present inventors have come to develop the polyurethane colorant composition of the present invention which is superior in quality and performance to foreign products after the research efforts in recent years.
본 발명의 목적은 스폰지와 신발(shoes sole)에 사용되는 폴리우레탄을 원하는 색상에 따라 착색할 수 있는 착색제 조성물을 제공하기 위한 것이다.An object of the present invention is to provide a colorant composition capable of coloring a polyurethane used in a sponge and a shoe sole according to a desired color.
본 발명의 다른 목적은 폴리우레탄을 균일하고 고농도로 착색할 수 있는 착색제 조성물을 제공하기 위한 것이다.Another object of the present invention is to provide a colorant composition capable of coloring a polyurethane uniformly and in high concentration.
본 발명의 또 다른 목적은 폴리우레탄을 용이하게 착색할 수 있도록 액상의 착색제 조성물을 제공하기 위한 것이다.Another object of the present invention is to provide a liquid colorant composition so that the polyurethane can be easily colored.
본 발명의 또 다른 목적은 30㎛ 이하의 입도를 가짐으로써 착색된 폴리우레탄의 불량률을 저하시킬 수 있는 착색제 조성물을 제공하기 위한 것이다.Still another object of the present invention is to provide a colorant composition capable of reducing the defective rate of colored polyurethane by having a particle size of 30 μm or less.
본 발명의 상기의 목적 및 기타의 목적들은 하기 설명되는 본 발명에 의하여 모두 달성될 수 있다. 이하 본 발명의 상세한 내용을 하기에 설명한다.The above and other objects of the present invention can be achieved by the present invention described below. Hereinafter, the details of the present invention will be described below.
본 발명은 폴리우레탄을 착색하기 위한 액상의 반응성 착색제 조성물로서, 이 조성물은 우레탄 결합을 가진 고분자쇄 내에 안료가 결합된 형태를 이루기 때문에, 안료가 자유로운(free) 분산상태가 아니고 고분자쇄에 결합된(bonded) 상태이므로 폴리우레탄 포움(foam) 형성시 부피 팽창에 잘 적응하여 균일하면서도 고농도의 색상을 낼 수 있다. 본 발명의 착색제 조성물내에 안료가 결합되는 구조는 하기 화학식(1)으로 표시될 수 있다:The present invention is a liquid reactive colorant composition for coloring a polyurethane, and since the composition forms a form in which a pigment is bound in a polymer chain having a urethane bond, the pigment is not free dispersed but bound to the polymer chain. Since it is in a bonded state, it can adapt to volume expansion when forming polyurethane foam, thereby producing a uniform and high concentration of color.

본 발명에 따른 액상의 반응성 착색제 조성물을 제조하는 방법은 다음과 같다.The method for preparing a liquid reactive colorant composition according to the present invention is as follows.
바인더 수지로서의 폴리올과 안료를 혼합하여 분산기내에서 안료를 분산시킨다. 동일 분산기에 경화제로 사용되는 디이소시아네이트와 촉매를 투입하여 반응시킨다. 이 반응은 40∼180℃의 온도에서 1∼10 시간동안 반응시킨다.The polyol as a binder resin and the pigment are mixed to disperse the pigment in the disperser. In the same disperser, a diisocyanate used as a curing agent and a catalyst are added and reacted. This reaction is made to react for 1 to 10 hours at the temperature of 40-180 degreeC.
상기 결과 반응물을 분산기 밀(mill)로서 밀링(milling)한다. 분산기는 3-롤 밀, 바스켓 밀, 수평 밀, 수직 밀 등이 적절하게 사용될 수 있다.The resulting reactant is milled as a disperser mill. Dispersers may be suitably used three-roll mill, basket mill, horizontal mill, vertical mill and the like.

It is usually desirable to prepare a colorant composition having a particle size of 30 μm or less, which can produce a colorant composition having a required particle size by adjusting the mesh of the filter.

실시예Example
실시예 1Example 1
바인더 수지로서 폴리에테르 폴리올 50 중량부와 안료로서 카본블랙 30 중량부를 혼합기에 넣어 혼합하고, 상기 혼합물에 경화제로서 톨루엔디이소시아네트 5 중량부와 주석 촉매 2 중량부를 넣었다. 상기 반응물을 90℃로 상승시켜 2시간동안 반응시키고, 아민류 분산제 3 중량부와 용매로서 n-부탄올 5 중량부를 넣어 분산시키고, 3-롤 밀로써 밀링한 후, 200 메쉬의 필터로 여과하여 입도 20㎛를 갖는 착색제 조성물을 제조하였다. 여기서 얻어진 액상의 착색제 조성물로써 폴리우레탄을 착색한 결과 원하는 색상을 갖는 폴리우레탄이 생산되었다.50 parts by weight of a polyether polyol as a binder resin and 30 parts by weight of carbon black as a pigment were mixed in a mixer, and 5 parts by weight of toluene isocyanate and 2 parts by weight of a tin catalyst were added as a curing agent. The reaction was heated to 90 ° C. for 2 hours, dispersed in 3 parts by weight of an amine dispersant and 5 parts by weight of n-butanol as a solvent, milled with a 3-roll mill, and filtered through a 200 mesh filter to obtain a particle size of 20 A colorant composition having a μm was prepared. As a result of coloring the polyurethane with the liquid colorant composition obtained here, a polyurethane having a desired color was produced.
실시예 2Example 2
실시예 1에서, 아민류 분산제 3 중량부와 용매로서 n-부탄올 5 중량부를 넣어 분산시키는 단계를 3-롤 밀로써 밀링한 후에 행하는 것을 제외하고는 실시예1과동일한 방법으로 착색제 조성물을 제조하였다. 여기서 얻어진 액상의 착색제 조성물로써 폴리우레탄을 착색한 결과 원하는 색상을 갖는 폴리우레탄이 생산되었다.In Example 1, a colorant composition was prepared in the same manner as in Example 1, except that 3 parts by weight of the amine dispersant and 5 parts by weight of n-butanol as a solvent were dispersed after milling with a 3-roll mill. As a result of coloring the polyurethane with the liquid colorant composition obtained here, a polyurethane having a desired color was produced.
실시예 3Example 3
실시예 1에서, 폴리에테르 폴리올 대신에 폴리에스테르 폴리올을 사용하고, TDI 대신에 MDI를 사용하는 것을 제외하고는 실시예 1과 동일한 방법으로 착색제 조성물을 제조하였다. 여기서 얻어진 액상의 착색제 조성물로써 폴리우레탄을 착색한 결과 원하는 색상을 갖는 폴리우레탄이 생산되었다.In Example 1, a colorant composition was prepared in the same manner as in Example 1 except for using a polyester polyol instead of a polyether polyol and using MDI instead of TDI. As a result of coloring the polyurethane with the liquid colorant composition obtained here, a polyurethane having a desired color was produced.
본 발명은 스폰지 및 신발 밑창에 사용되는 폴리우레탄을 원하는 색상에 따라 균일하게 고농도로 착색할 수 있으며, 상기 착색을 용이하게 하도록 액상 타입으로 제조되며, 또한 30㎛ 이하의 입도를 가짐으로써 착색된 폴리우레탄의 불량율을 저하시킬 수 있는 착색제 조성물을 제공하는 효과를 갖는다.According to the present invention, the polyurethane used for the sponge and the shoe sole can be uniformly colored in a high concentration according to a desired color, and is manufactured in a liquid type to facilitate the coloring, and also has a colored particle having a particle size of 30 μm or less. It has the effect of providing the coloring agent composition which can reduce the defective rate of a urethane.
본 발명의 단순한 변형 내지 변경은 모두 본 발명의 영역에 속하는 것으로 본 발명의 구체적인 보호범위는 첨부된 특허청구범위에 의하여 명확해질 것이다.All simple modifications and variations of the present invention fall within the scope of the present invention, and the specific scope of the present invention will be apparent from the appended claims.
