Hereinafter, preferred embodiments of the present invention and physical properties of the respective components will be described in detail with reference to the accompanying drawings. However, the present invention is not limited thereto, And this does not mean that the technical idea and scope of the present invention are limited.

본 발명에 따른 유무기 하이브리드 코팅제는 무기계 졸이 혼합된 주재 100 중량부 및 경화제 30 내지 40 중량부로 이루어진다.
The organic-inorganic hybrid coating according to the present invention comprises 100 parts by weight of a host material mixed with an inorganic sol and 30 to 40 parts by weight of a curing agent.

상기 무기계 졸이 혼합된 주재는 무기계 졸 100 중량부, 에탄올 15 내지 30 중량부, 에틸렌 글리콜 모노에틸에테르 30 내지 45 중량부 및 메틸트리메톡시실란 30 내지 45 중량부로 이루어진다.The inorganic material in which the inorganic sol is mixed is composed of 100 parts by weight of an inorganic sol, 15 to 30 parts by weight of ethanol, 30 to 45 parts by weight of ethylene glycol monoethyl ether and 30 to 45 parts by weight of methyltrimethoxysilane.

상기 주재에는 무기계 졸이 혼합되어 기존에 유기계 성분으로만 이루어진 코팅제에 비해 부착강도, 내열성 및 내마모성이 우수하고, 경도가 높은 코팅막이 제공된다.The present invention provides a coating film having excellent adhesion strength, heat resistance and abrasion resistance, and high hardness, as compared with a conventional coating material composed of an organic component by mixing an inorganic sol.

이때, 상기 무기계 졸은 이소프로필알코올 100 중량부, 글리시딜옥시프로필트리메톡시실란 100 내지 200 중량부, 테트라에틸오소실리케이트 50 내지 150 중량부 및 pH가 2 이하로 조절된 산 수용액 200 내지 300 중량부를 혼합하고, 상온에서 3 내지 5시간 동안 가수분해하여 제조되는데, 더욱 상세하게는 이소프로필알코올 100 중량부에 글리시딜옥시프로필트리메톡시실란 100 내지 200 중량부, 테트라에틸오소실리케이트 50 내지 150 중량부를 혼합하고, 염산, 질산, 황산 및 인산으로 이루어진 그룹에서 선택된 하나 이상의 산을 정제수와 혼합하여 산 수용액을 제조하되, pH가 2 이하를 나타내도록 혼합한 후에 혼합하고 상온에서 3 내지 5시간 동안 가수분해하여 제조된다.The inorganic sol may include 100 parts by weight of isopropyl alcohol, 100 to 200 parts by weight of glycidyloxypropyltrimethoxysilane, 50 to 150 parts by weight of tetraethylorthosilicate and 200 to 300 parts by weight of an acid aqueous solution having a pH of 2 or less And 100 to 200 parts by weight of glycidyloxypropyltrimethoxysilane and 50 to 200 parts by weight of tetraethylorthosilicate are added to 100 parts by weight of isopropyl alcohol, And at least one acid selected from the group consisting of hydrochloric acid, nitric acid, sulfuric acid and phosphoric acid is mixed with purified water to prepare an aqueous acid solution, which is mixed so as to exhibit a pH of 2 or less, followed by mixing at room temperature for 3 to 5 hours ≪ / RTI >

상기의 과정을 통해 제조된 무기계 졸 100 중량부는 에탄올 15 내지 30 중량부, 에틸렌 글리콜 모노에틸에테르 30 내지 45 중량부 및 메틸트리메톡시실란 30 내지 45 중량부와 혼합되어 주재를 형성한다.
100 parts by weight of the inorganic sol prepared through the above process is mixed with 15 to 30 parts by weight of ethanol, 30 to 45 parts by weight of ethylene glycol monoethyl ether and 30 to 45 parts by weight of methyltrimethoxysilane to form a host.

상기 경화제는 30 내지 40 중량부가 함유되며, 상기 주재와 혼합되면 경화되는 특성을 나타내어 코팅막이 형성되도록 하는 역할을 하는데, 변성지환족아민 100 중량부, 에틸렌 글리콜모노에틸에테르 5 내지 15 중량부, 아미노프로필트리에톡시실란 1 내지 5 중량부 및 첨가제 0.5 내지 2 중량부로 이루어진다.The curing agent is contained in an amount of 30 to 40 parts by weight and is cured when mixed with the host material to form a coating film. The curing agent is a mixture of 100 parts by weight of a denatured nitrogenous amine, 5 to 15 parts by weight of ethylene glycol monoethyl ether, 1 to 5 parts by weight of triethoxysilane and 0.5 to 2 parts by weight of an additive.

상기 경화제의 함량이 30 중량부 미만이면 경화속도가 더뎌 코팅공정의 효율성이 저하되며, 상기 경화제의 함량이 40 중량부를 초과하게 되면 경화속도가 지나치게 증가하여 코팅제의 가공성이 저하된다.If the content of the curing agent is less than 30 parts by weight, the curing rate is slowed to reduce the efficiency of the coating process. When the content of the curing agent is more than 40 parts by weight, the curing rate is excessively increased.

이때, 상기 첨가제는 소포제, 레벨링제 및 분리저감제로 이루어진 그룹에서 선택된 하나 이상으로 이루어지며, 상기 소포제, 레벨링제 및 분리저감제의 성분은 2액형 코팅제 조성물의 경화제에 사용되는 통상의 성분이면 특별히 한정되지 않고, 어떠한 것이든 사용가능하다.At this time, the additive is composed of at least one selected from the group consisting of a defoaming agent, a leveling agent and a separating reducing agent, and the components of the defoaming agent, the leveling agent and the separation reducing agent are particularly limited as long as they are ordinary components used for a curing agent of a two- And any of them can be used.

상기와 같이 주재 100 중량부에 경화제 30 내지 40 중량부를 혼합하여 제조되는 코팅제는 주재와 경화제를 혼합한 후에 교반하고, 스프레이나 롤러 등을 이용하여 미착물에 도포되는데, 이때, 도막의 두께는 1회 도포를 기준으로 25 내지 40㎛인 것이 바람직하다.As described above, the coating material prepared by mixing 30 to 40 parts by weight of the curing agent with 100 parts by weight of the main material is applied to the uncoupled material by mixing with the curing agent after mixing the main material and the curing agent. It is preferably 25 to 40 mu m on the basis of the spin coating.

또한, 상기의 과정으로 도포되어 형성된 코팅층은 가수분해과정으로 합성된 무기계 졸이 혼합된 주재와 상기의 성분으로 이루어지는 경화제의 화학반응을 통해 내열성 및 내마모성이 우수하고, 가구용 원목의 색감을 저하시키지 않으면서 경도가 높은 코팅막을 제공한다.
In addition, the coating layer applied and formed by the above process is excellent in heat resistance and wear resistance through chemical reaction between the host material in which the inorganic sol synthesized by the hydrolysis process is mixed and the curing agent composed of the above components, Thereby providing a coating film having a high hardness.

또한, 상기 유무기 하이브리드 코팅제에는 상기 유무기 하이브리드 코팅제 100 중량부 대비 소광제 5 내지 10 중량부가 더 함유될 수도 있는데, 상기 소광제는 상기 유무기 하이브리드 코팅제의 광택도를 낮춰주는 역할을 하기 때문에, 본 발명에 따른 유무기 하이브리드 코팅제가 가구용 원목에 적용되었을 때, 표면 광택의 지나친 증가로 인해 소비자로 하여금 저가형 가구제품으로 인식될 우려가 없다.The organic or inorganic hybrid coating may further contain 5 to 10 parts by weight of a quencher relative to 100 parts by weight of the organic / inorganic hybrid coating. Since the quencher reduces the gloss of the organic / inorganic hybrid coating, When the organic-inorganic hybrid coating agent according to the present invention is applied to the timber for furniture, an excessive increase in surface gloss does not cause the consumer to be recognized as a low-cost furniture product.

상기 소광제의 함량이 5 중량부 미만이면 상기와 같은 소광효과가 미미하여 가구제품의 상품성이 저하될 수 있으며, 상기 소광제의 함량이 10 중량부를 초과하게 되면 가구용 원목에 적용되는 코팅제의 광택성이 지나치게 낮아져 코팅효과가 저하될 수 있다.If the amount of the quencher is less than 5 parts by weight, the quenching effect is insignificant as described above, which may degrade the merchantability of household products. If the quencher exceeds 10 parts by weight, the gloss of the coating agent applied to the wood The coating effect may be lowered.

이때, 상기 소광제는 이산화규소로 이루어지는 것이 바람직하다.
At this time, it is preferable that the quencher is made of silicon dioxide.

이하에서는, 본 발명에 따른 유무기 하이브리드 코팅제의 제조방법 및 물성을 실시예를 들어 설명하기로 한다.
