Description
본 발명은 무광택 및 투명 세라믹 코팅제 조성물에 관한 것이다. 보다 상세하게는 초음파 분산을 이용하여 투명한 무광택막을 형성시킬 수 있는 세라믹 코팅제 조성물에 관한 것이다.The present invention relates to matte and transparent ceramic coating compositions. More particularly, the present invention relates to a ceramic coating composition capable of forming a transparent matte film using ultrasonic dispersion.
최근 유기규소 화합물은 그의 응용기술 발달로 규소원자의 특성을 이용한 전기적, 화학적, 열적안정성을 필요로 하는 각종 산업분야에서 사용되고 있다. 유기 규소 화합물의 대표적인 것으로는 클로로실란, 알콕시실란, 실란커플링제, 불소 알킬 실란, 반응성 실록산 올리고머 등이 그 예이다.Recently, organosilicon compounds have been used in various industrial fields requiring electrical, chemical, and thermal stability using characteristics of silicon atoms due to their application technology. Typical examples of the organosilicon compounds are chlorosilanes, alkoxysilanes, silane coupling agents, fluorine alkyl silanes, reactive siloxane oligomers, and the like.
한편, 세라믹 코팅제는 상기 클로로실란을 알콕시화하여 얻은 알콕시실란을 산 또는 알카리 촉매하에서 적당량의 물과 알콜 등의 용제 및 충진제, 안료, 첨가제 등을 첨가하여 제조하고 있으며, 그 응용 분야의 확대와 함께 유광 및 무광의 투명 코팅제의 용도가 확대되고 있다.On the other hand, the ceramic coating agent is prepared by alkoxysilane obtained by the alkoxylation of the chlorosilane by adding an appropriate amount of solvents and fillers, pigments, additives, etc., under an acid or alkali catalyst, with the expansion of the application field The use of glossy and matt transparent coatings is expanding.
특히 액자유리, 화장품병, 유리컵, 도금보호용 코팅제, 주방기물, 건축용 내외장재, TV브라운관, 각종 금속 장식물 등의 분야에서 광택이 없으면서 균일한 투명막의 무기코팅제의 수요가 증대되고 있으나, 종래의 무광택 및 투명 코팅제는 제조시 광택을 소실시키는 방법으로서 흄드실리카, 탈크, 화이트카본 등 초미세 파우더를 첨가한 제조물과 수지분인 알콕시실란 등의 첨가량을 감소시켜 제조한 조성물이 주종을 이루고 있어 제조 후 시간이 경과되는 정도에 따라서 광택도의 변화가 심하고 코팅제의 사용자에 따른 도막의 두께의 차이에 따라서 광택도가 일정하지 않아 그 용도에 따른 후막 및 박막의 조정이 어렵고, 제조후 사용시간 및 도막의 두께에 따른 정도 차이에 따라서 광택도가 다르며, 충진제의 형상과 크기에 따라 차이가 있으나, 시간이 경과 후 충진제 및 소광제의 입자사이에 존재하는 수지가 다시 표면으로 나와 광택도가 증가하는 등 투명한 무광택 막을 일정한 상태로 재현하기가 매우 어려웠다.In particular, in the fields of frame glass, cosmetic bottles, glass cups, coating protective coatings, kitchenware, building interior and exterior materials, TV brown tube, and various metal decorations, there is an increasing demand for an inorganic coating agent having a uniform transparent film without the gloss. The transparent coating is a method of dissipating the gloss during manufacture, and the composition prepared by reducing the amount of addition of ultrafine powders such as fumed silica, talc, and white carbon and alkoxysilane, which is a resin powder, is predominantly time after preparation. The degree of gloss varies greatly depending on the degree of elapsed, and the glossiness is not constant according to the difference in the thickness of the coating film according to the user of the coating agent. The degree of gloss is different according to the degree of difference and the shape and size of the filler are different. After elapse of time, it was very difficult to reproduce the transparent matte film in a constant state such that the resin existing between the particles of the filler and the matting agent came out again to increase the glossiness.
이에 본 발명자들은 상기와 같은 문제점을 해결하고자, 예의 연구한 결과, 코팅제 조성물을 이루는 구성 성분 중 수지성분의 양을 조절하고, 충진제 또는 소광제로서, 입자크기가 서로 다른 콜로이달 실리카 또는 콜로이달 알루미나를 이용하는 경우, 장기간 광택도가 일정하면서 수지분의 감소 및 충진제 또는 소광제의 과다 투여로 인한 도막의 물성열화없이 안정된 도막을 실현할 수 있음을 발견하였다.In order to solve the above problems, the present inventors have made a thorough study to adjust the amount of the resin component of the components constituting the coating composition, and as a filler or quencher, colloidal silica or colloidal alumina having different particle sizes In the case of using, it has been found that a stable coating film can be realized without deterioration of physical properties of the coating film due to a decrease in resin content and excessive administration of a filler or a matting agent while maintaining a long gloss.
이에 본 발명은 무광택의 투명한 세라믹 도료를 얻을 수 있는 세라믹 코팅제 조성물을 제공하는 것을 목적으로 한다.Accordingly, an object of the present invention is to provide a ceramic coating composition capable of obtaining a matt transparent ceramic paint.
