본 발명의 일 실시예에 의하면, 본 발명은 종래의 이액형 아크릴 실리콘계 도료 조성물을 일액형화함으로써, 도장 작업시 주제와 경화제를 혼합해야하는 과정을 거칠 필요가 없고, 이액형이 가지고 있는 가사 시간에 따른 도장작업 시간의 제약을 해소할 수 있는 효과가 있다.According to one embodiment of the present invention, the present invention does not need to go through the process of mixing the main agent and the curing agent during the painting work by one-component molding of the conventional two-component acrylic silicone coating composition, the pot life of the two-component There is an effect that can eliminate the constraints of the painting work time.

한편, 본 발명은 고경도를 가지고 있으며, 내스크레치성 및 저장성에서도 우수한 효과를 가지고 있다.On the other hand, the present invention has a high hardness, and has an excellent effect in scratch resistance and shelf life.
이하, 본 발명의 바람직한 실시예를 상세히 설명한다. 또한, 하기에서 본 발명을 설명함에 있어, 관련된 공지기능 또는 구성에 대한 구체적인 설명이 본 발명의 요지를 불필요하게 흐릴 수 있다고 판단되는 경우에는 그 상세한 설명을 생략한다.Hereinafter, preferred embodiments of the present invention will be described in detail. In the following description of the present invention, detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.
본 발명은 아크릴 수지 40~60중량부, 에폭시 실란 5~10중량부, 소포제 0.01~0.1중량부, 폴리아미드 왁스 디스퍼젼형 침강방지제 1~3중량부, 유기용제 5~15중량부의 비율로 이루어진다.
The present invention comprises 40 to 60 parts by weight of acrylic resin, 5 to 10 parts by weight of epoxy silane, 0.01 to 0.1 part by weight of antifoaming agent, 1 to 3 parts by weight of polyamide wax dispersion type antisettling agent, and 5 to 15 parts by weight of organic solvent. .
또한, 본 발명에서 아크릴 수지에 사용되는 원료는 에틸 아크릴레이트 모노머 40~60중량부, 스티렌 단량체 20~40중량부, 2-하이드로실에틸 메타아크릴레이트 10~30중량부, 라디칼 중합개시제 0.1~1.0중량부, 유기용제 30~50중량부를 포함한다.
In addition, the raw material used for the acrylic resin in the present invention is 40 to 60 parts by weight of ethyl acrylate monomer, 20 to 40 parts by weight of styrene monomer, 10 to 30 parts by weight of 2-hydroylethyl methacrylate, 0.1 to 1.0 radical polymerization initiator It includes weight part and 30-50 weight part of organic solvents.
한편, 본 발명에서 소재와의 부착성을 높이기 위해 에폭시 실란을 도입하였다. 실란은 에스터 실란, 비닐실란, 메타크리록시 실란, 에폭시 실란, 아미노 실란, 유레이도 실란이 포함될 수 있다. 특히 에폭시 실란은 감마-글리시독시프로필트리메톡시 실란, 베타-에폭시씨클로헥실에틸트리메톡시 실란으로 이루어진 군에서 하나를 선택하여 사용하며 이를 사용함으로써 소재와의 높은 부착성을 보인다.
Meanwhile, in the present invention, an epoxy silane was introduced to increase the adhesion with the material. The silanes may include ester silanes, vinylsilanes, methacryloxy silanes, epoxy silanes, amino silanes, and ureido silanes. In particular, the epoxy silane is selected from the group consisting of gamma-glycidoxypropyltrimethoxy silane, beta-epoxycyclohexylethyltrimethoxy silane, and by using it, it shows high adhesion to the material.
에폭시 실란 화합물은 SILQUEST사의 A-187 제품으로 5~10중량부를 사용하는 것이 바람직하며, 에폭시기가 가교에 참여함으로써 보다 좋은 결합을 얻을 수 있으며, 내수성 및 내약품성을 좋게 할 수 있다. 또한 무황변타입으로 에폭시의 단점을 보완할 수 있다. 에폭시 실란 화합물은 5~10중량부를 포함하는 것이 바람직하며, 이는 에폭시 실란 화합물이 5중량부 미만으로 포함될 경우 도막의 경도가 저하되는 문제점이 발생하고, 10중량부를 초과하면 도막의 경도가 높아져 내충격성 및 내굴곡성 시험시 도막의 깨어짐 현상이 발생하기 때문이다.
The epoxy silane compound is preferably 5 to 10 parts by weight as A-187 manufactured by SILQUEST, and better bonding can be obtained by the epoxy group participating in the crosslinking, and water and chemical resistance can be improved. In addition, the yellowing type can compensate for the disadvantages of epoxy. It is preferable that the epoxy silane compound contains 5 to 10 parts by weight, which causes a problem that the hardness of the coating film is lowered when the epoxy silane compound is included in less than 5 parts by weight. And cracking of the coating occurs during the flex resistance test.
본 발명에서 폴리아미드 왁스 디스퍼전형 침강방지제는 미국 킹인더스트리의 DISPARLON 6900-20X 제품으로 침강방지와 흐름성방지 역할을 한다. 1~3중량부를 사용하는 것이 바람직하며, 1중량부 미만으로 사용하는 경우 조성물의 도장시 조성물이 밑으로 흐르는 문제점 및 조성물의 저장기간에 안료가 침강하는 문제점이 생기고, 3중량부를 초과하면 도료의 점도가 높아져 도장시 도막의 레벨링 및 도막의 균열이 발생하는 문제가 생기기 때문이다.
In the present invention, the polyamide wax dispersion type anti-settling agent plays a role of anti-sedimentation and flow prevention as a DISPARLON 6900-20X product of King Industries. It is preferable to use 1 to 3 parts by weight, and when used at less than 1 part by weight, there is a problem that the composition flows down when the composition is coated and a problem that the pigment precipitates during the storage period of the composition. This is because the viscosity increases, causing problems such as leveling of the coating film and cracking of the coating film during coating.
본 발명에서 유기용제는 케톤류 및 방향족계 탄화수소를 사용한다. 케톤류는 아크릴수지를 잘 녹이는 진용제로 수지의 점도를 낮춰 조성물의 다른 성분들과 잘 섞이도록 하는 역할을 하며, 방향족계 탄화수소는 케톤류의 진용제를 보조하는 값이 싼 보조용제이다.
In the present invention, the organic solvent uses ketones and aromatic hydrocarbons. Ketones are soluble solvents that dissolve acrylic resins to lower the viscosity of the resin to mix well with the other components of the composition. Aromatic hydrocarbons are inexpensive auxiliary solvents that assist ketogenic salts.
여기서, 케톤류로는 아세톤, 메틸에틸케톤, 메틸이소부틸케톤 등을 사용할 수 있으며, 특히 수지와의 상용면에서 메틸에틸케톤을 사용하는 것이 바람직하다. 또한, 방향족계 탄화수소로는 자일렌, 톨루엔 등을 사용할 수 있으며, 특히, 도료광택 면에서 자일렌을 사용하는 것이 바람직하다.
Here, as the ketones, acetone, methyl ethyl ketone, methyl isobutyl ketone and the like can be used, and in particular, it is preferable to use methyl ethyl ketone in terms of compatibility with the resin. In addition, xylene, toluene and the like can be used as the aromatic hydrocarbon, and in particular, it is preferable to use xylene in terms of coating gloss.
또한, 유기용제는 5~15중량부로 포함하는 것이 바람직하며, 5중량부 미만으로 포함되는 경우 조성물이 잘 섞이지 않으며 도료의 광택도 나빠지는 문제가 생기고, 15중량부를 초과하면 도료의 점도가 너무 낮아져 도료의 사용시 흐르는 현상이 발생하며 또한 은폐율이 떨어지는 문제가 생기기 때문이다.
In addition, the organic solvent is preferably included in 5 to 15 parts by weight, if less than 5 parts by weight of the composition does not mix well and the gloss of the paint is a problem, if the content exceeds 15 parts by weight of the paint is too low This is because the phenomenon of flowing during the use of the paint and also the problem of falling concealment rate occurs.
이하, 하기의 실시예를 통하여 본 발명을 좀 더 구체적으로 설명한다. 하기의 실시예는 본 발명의 내용을 보다 구체적으로 설명하기 위한 것으로 본 발명의 범위가 이에 한정되는 것은 아니다.
Hereinafter, the present invention will be described in more detail with reference to the following examples. The following examples are provided to more specifically describe the contents of the present invention, but the scope of the present invention is not limited thereto.

표 2에 나타난 바와 같이, 실시예1 내지 3은 연필경도가 높게 나오는 결과를 통해 도막의 경도 정도가 높다는 것을 알수 있으며, 또한 도료의 광택이 높아 다양한 광택 구현이 가능하다는 장점이 있다.
As shown in Table 2, Examples 1 to 3 can be seen that the degree of hardness of the coating film is high through the results of the pencil hardness is high, and also has the advantage that high gloss of the paint can be implemented a variety of gloss.
반면에, 비교예는 광택이 낮아 다양한 광택 구현을 구현하는데 어려움이 있으며, 또한 연필경도 시험에서 연필경도가 실시예보다는 낮은 F로 나와 도막의 경도에서 문제점을 보이고 있다.On the other hand, the comparative example is difficult to implement a variety of gloss due to the low gloss, and also shows a problem in the hardness of the coating film came out in a pencil hardness F lower than the example in the pencil hardness test.
