Description

시멘트와의 상용성이 우수한 착색조성물{A COLORING COMPOSITION HAVING A GOOD COMPATIBILITY WITH CEMENT}Color composition with excellent compatibility with cement {A COLORING COMPOSITION HAVING A GOOD COMPATIBILITY WITH CEMENT}

본 발명은 시멘트제품에 사용되는 착색제에 관한 것으로서, 특히 시멘트와의 상용성이 우수한 프탈로시아닌계 착색조성물에 관한 것이다.The present invention relates to a colorant used in cement products, and more particularly to a phthalocyanine-based coloring composition having excellent compatibility with cement.

시멘트 가공제품인 벽돌이나 보도,차도용 블록 등의 시멘트 2차제품 및 도로 포장용, 토목용 등 콘크리트 몰탈의 착색을 위해서 다양한 종류의 안료가 사용되고 있다.Various types of pigments are used for coloring cement mortars such as bricks, sidewalks and roadway blocks, which are cement processing products, and road paving and civil engineering.

종래에는 시멘트 제품에 녹색이나 청색의 색상을 부여하기 위하여 착색제로 서 산화크롬(chrome oxide), 코발트블루(cobalt blue), 군청(marine blue) 등을 사용하였다.Conventionally, chromium oxide, chromium blue, cobalt blue, and the like were used as colorants to give green or blue colors to cement products.

그러나, 이러한 착색제는 그 물성에 비하여 가격이 지나치게 비싸다.However, these colorants are too expensive for their physical properties.

통상적인 안료의 경우에는 그 계면이 소수성이기 때문에 인쇄잉크, 페인트, 고무, 플라스틱 등에는 잘 혼화되지만 물에는 균일하게 분산되기 어려워 시멘트 제품에 사용하기에는 적합하지 않다.In the case of conventional pigments, since the interface is hydrophobic, it is well mixed with printing inks, paints, rubbers, plastics, etc., but is not suitable for use in cement products because it is difficult to uniformly disperse in water.

또한, 크롬산연계 녹색이나 아이언블루(iron blue)계 안료는 내수성, 내알카리성이 약하여 시멘트 제품의 착색제로서 부적합하다.In addition, chromate-based green and iron blue pigments are poor in water resistance and alkali resistance and are not suitable as colorants in cement products.

통상적으로 널리 사용되는 프탈로시아닌계 안료의 경우에는 시멘트와의 비중 차이가 크기 때문에 시멘트 몰탈이나 콘크리트 조성물에 쉽게 분산되지 않아 균일한 색상을 얻기가 힘들다.In the case of phthalocyanine-based pigments that are widely used in general, since the specific gravity difference with cement is large, it is difficult to obtain uniform colors because they are not easily dispersed in cement mortar or concrete composition.

따라서, 본 발명은 이와같은 종래의 기술적 문제점을 해소하기 위해 안출되었다.Accordingly, the present invention has been made to solve such a conventional technical problem.

즉, 본 발명의 목적은 가격이 저렴하면서도 시멘트와의 상용성이 뛰어난 착색조성물 및 그 제조방법을 제공하는 것이다.That is, an object of the present invention is to provide a coloring composition having a low cost and excellent compatibility with cement and a method of manufacturing the same.

본 발명자들은 시멘트제품의 착색제로서 프탈로시아닌계 안료를 사용하는 것이 가격면과 물성면에서 적절하다는 사실을 알았다.The present inventors found that the use of phthalocyanine-based pigments as colorants in cement products is appropriate in terms of price and physical properties.

하지만, 프탈로시아닌계 안료는 그 계면이 소수성이고 시멘트와의 비중차이가 크기 때문에 그대로 시멘트에 적용하기는 힘들다.However, phthalocyanine-based pigments are difficult to apply to cement as they are hydrophobic in interface and have a large difference in specific gravity from cement.

따라서, 본 발명자들은 프탈로시아닌계 안료에 계면활성제를 첨가하여 그 계면을 친수성으로 전환시키고, 체질안료와 같은 증량제를 투입하여 시멘트와의 비중 차이를 극복하였다.Therefore, the present inventors added a surfactant to the phthalocyanine-based pigment to convert the interface to hydrophilic, and added an extender such as a extender pigment to overcome the difference in specific gravity with cement.

또한, 가격상승을 방지하기 위해 본 발명에서는 40 ~ 70중량%의 물과 30 ~ 60중량%의 프탈로시아닌 안료를 함유하는 안료겔(gel)(일명, 프레스케익; presscake)을 사용한다. 계면활성제는 0.2 ~ 2중량% 정도 투입되었고, 계면활성제의 종류는 양이온 계면활성제, 음이온 계면활성제 및 비이온성 계면활성제중 어느 하나를 사용하였다.In addition, in order to prevent the price increase, the present invention uses a pigment gel (aka, presscake) containing 40 to 70% by weight of water and 30 to 60% by weight of phthalocyanine pigment. The surfactant was added in about 0.2 to 2% by weight, and the type of the surfactant was any one of a cationic surfactant, an anionic surfactant, and a nonionic surfactant.

본 발명의 착색조성물은 시멘트와의 비중 차이를 극복하기 위해서 증량제를 투입한다. 이 증량제의 투입량과 안료겔(프레스 케익)의 투입량은 착색의 정도에 따라 당업자가 적절히 조절한다.In the coloring composition of the present invention, an extender is added to overcome the difference in specific gravity with cement. The dose of this extender and the dose of pigment gel (press cake) are appropriately adjusted by those skilled in the art according to the degree of coloring.

본 발명의 다른 목적 및 장점들은 하기에 설명될 것이며, 본 발명의 실시에 의해 알게 될 것이다. 또한, 본 발명의 목적 및 장점들은 첨부된 특허청구범위에 나타낸 수단 및 조합에 의해 실현될 수 있다.Other objects and advantages of the invention will be described below and will be appreciated by the practice of the invention.

상기 프레스케익은 40 ~ 70중량%의 물과 30 ~ 60중량%의 프탈로시아닌 안료로 구성된다. 프탈로시아닌 안료는 프탈로시아닌 그린과 블루를 모두 포함하는 유기안료이다.The press cake is composed of 40 to 70% by weight of water and 30 to 60% by weight of phthalocyanine pigment. Phthalocyanine pigments are organic pigments containing both phthalocyanine green and blue.

상기 계면활성제(surface active agent)는 양이온 계면활성제, 음이온 계면활성제와 같은 이온성 계면활성제 및 비이온성 계면활성제중 어느 것이든 사용 가능하다.The surface active agent may be any of an ionic surfactant such as a cationic surfactant, an anionic surfactant, and a nonionic surfactant.

프레스 케익에 첨가되는 계면활성제의 함량은 0.2 ~ 2중량% 정도가 적합하다.The amount of the surfactant added to the press cake is preferably about 0.2 to 2% by weight.

이 계면활성제는 프탈로시아닌의 계면에 존재하는 소수성기를 친수성기로 전환하여 안료와 시멘트의 상용성을 증대시킨다.This surfactant converts the hydrophobic groups present at the interface of the phthalocyanine to hydrophilic groups to increase the compatibility of the pigment with the cement.

특히, 본 발명에 있어서는 이 계면활성제로서 HLB(Hydrophilic Lipophilic Balance) 10 ~ 15를 사용하는 것이 바람직하다.In particular, in the present invention, it is preferable to use HLB (Hydrophilic Lipophilic Balance) 10 to 15 as the surfactant.

상기 체질안료는 일종의 증량제로서 프탈로시아닌 안료와 시멘트의 비중차이를 해소하기 위해 첨가되는 것이다.The extender pigment is added as a kind of extender to solve the difference in specific gravity between phthalocyanine pigment and cement.

본 발명에 사용되는 체질안료로서는 실리카분말(silica powder), 카올린 (kaoline), 탄산칼슘, 알루미늄실리케이트(aluminum silicate), 산화알루미늄, 산화마그네슘 및 산화철이 사용된다.As the extender pigments used in the present invention, silica powder, kaoline, calcium carbonate, aluminum silicate, aluminum oxide, magnesium oxide and iron oxide are used.

본 발명의 착색조성물에는 상기 체질안료중 어느 하나가 단독으로 첨가되든지 또는 상기 체질안료중 적어도 하나 이상을 포함하는 혼합물이 첨가될 수 있다.The coloring composition of the present invention may be added either one of the extender pigments alone or a mixture containing at least one of the extender pigments.

또한, 본 발명의 착색조성물을 구성하는 프레스케익(즉, 프탈로시아닌 안료)과 체질안료는 시멘트의 착색 정도에 따라 그 함량이 적절히 조절된다.In addition, the content of the press cake (ie, phthalocyanine pigment) and the extender pigment constituting the colored composition of the present invention is appropriately adjusted according to the coloration of the cement.

당해 기술분야에서 통상의 지식을 가진자라면 본 발명의 착색조성물이 첨가되는 시멘트제품의 착색정도를 파악하여 체질안료와 프레스케익의 함량을 적절히 조절할 수 있을 것이다.Those skilled in the art will be able to appropriately control the content of the extender pigment and the press cake by grasping the coloring degree of the cement product to which the coloring composition of the present invention is added.

이하에서는 상술한 구성의 착색조성물을 제조하는 공정을 상세히 소개한다.Hereinafter, the process for producing the colored composition of the above-described configuration is introduced in detail.
