이하, 첨부된 도면을 참조하면서 본 발명의 바람직한 실시 예에 따른 부식방지 및 방수용 고분자 코팅 조성물과 이의 제조방법에 대하여 구체적으로 설명한다. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a corrosion inhibiting and waterproofing polymer coating composition according to a preferred embodiment of the present invention and a method of manufacturing the same will be described in detail with reference to the accompanying drawings.
본 발명의 고분자 코팅 조성물은 주제와 경화제를 혼합하여 조성한다. 가령, 주제 100중량부에 대하여 경화제 50 내지 150중량부를 혼합한다.The polymer coating composition of the present invention is prepared by mixing a base and a curing agent. For example, 50 to 150 parts by weight of a curing agent is mixed with 100 parts by weight of a subject.
주제는 에폭시 수지, 탈크, 티타니아, 흄드 실리카, 규사를 포함한다. The topics include epoxy resins, talc, titania, fumed silica, silica sand.
에폭시 수지의 예로 비스페놀 A형을 이용할 수 있다. 가령, 비스페놀A형 에폭시수지로 에폭시 당량 180~220g/eq(국도화학, YD-128) 정도의 것을 사용할 수 있다. 본 발명의 고분자 코팅 조성물의 전체 중량을 기준으로 에폭시수지를 15 내지 40중량%의 양으로 함유한다. 에폭시 수지의 함량이 15중량% 미만인 경우에는 기지재료(matrix)로서의 역할을 할 수 없으며, 40중량%를 초과하면 고분자 코팅 조성물의 물성이 저하될 수 있다. As an example of the epoxy resin, bisphenol A type can be used. For example, a bisphenol A type epoxy resin having an epoxy equivalent of 180 to 220 g / eq (National Chemical Industries, YD-128) can be used. The epoxy resin is contained in an amount of 15 to 40% by weight based on the total weight of the polymer coating composition of the present invention. If the content of the epoxy resin is less than 15% by weight, it can not serve as a matrix. If the content exceeds 40% by weight, the physical properties of the polymer coating composition may be deteriorated.
탈크는 조성물의 평활성과 흐름성을 개선시키기 위한 것으로서, 입도 크기는 200 내지 400메쉬인 것이 바람직하다. 탈크는 에폭시 수지 100중량부에 대하여 30 내지 70중량부가 첨가된다. 탈크의 첨가량이 30중량부 미만이면 조성물의 흐름성이 낮아지고, 70중량부를 초과하면 접착성이 저하된다. Talc is for improving the smoothness and flowability of the composition, and the particle size is preferably 200 to 400 mesh. Talc is added in an amount of 30 to 70 parts by weight based on 100 parts by weight of the epoxy resin. If the amount of the talc added is less than 30 parts by weight, the flowability of the composition is lowered, and if it exceeds 70 parts by weight, the adhesiveness is decreased.
티타니아로 이산화티탄을 이용할 수 있다. 이산화티탄은 항균성이 우수하며, 초친수성으로 코팅막의 자가세정(self cleaning) 효과를 부여한다. 티타니아는 에폭시 수지 100중량부에 대하여 15 내지 35중량부가 첨가된다. Titanium dioxide can be used as the titania. Titanium dioxide is excellent in antimicrobial activity and imparts a self-cleaning effect to the coating film due to its superhydrophilic property. Titania is added in an amount of 15 to 35 parts by weight based on 100 parts by weight of the epoxy resin.
흄드 실리카(fumed silica)는 퓸 형태로 만들어진 무수규산으로, 통상적으로 사염화규소(SiCl4)를 가열분해하여 화염수화(flame hydrolysis)시키는 과정에서 만들어진다. 흄드 실리카는 비표면적 200~220 m2/g, 밀도 0.16~0.22g/cm3로 표면적이 크고 입자가 미세하다는 특징을 갖는다. 흄드 실리카로 상업화된 독일의 데구사(degussa)나 일본의 도쿠야마사, 한국의 OCI 제품을 이용할 수 있다. 흄드 실리카는 조성물의 내식성을 증대시키고 분산성과 물성을 향상시킨다. 흄드 실리카는 에폭시 수지 100중량부에 대하여 5 내지 15중량부가 첨가된다. Fumed silica is anhydrous silicic acid made in the form of fumes, usually produced by flame hydrolysis of silicon tetrachloride (SiCl 4 ) by thermal decomposition. The fumed silica has a specific surface area of 200 to 220 m 2 / g and a density of 0.16 to 0.22 g / cm 3 , which is characterized by a large surface area and fine particles. Deucussa, Deutsche, Japan, and OCI products of Korea, which are commercialized as fumed silica, are available. Fumed silica increases the corrosion resistance of the composition and improves dispersibility and physical properties. The fumed silica is added in an amount of 5 to 15 parts by weight based on 100 parts by weight of the epoxy resin.
규사는 건조제와 흡착제의 기능을 부여하며, 입도 크기는 200 내지 400메쉬인 것이 바람직하다. 규사는 에폭시 수지 100중량부에 대하여 10 내지 20중량부가 첨가된다. Silica sand gives the function of a desiccant and an adsorbent, and the particle size is preferably 200 to 400 mesh. The silica sand is added in an amount of 10 to 20 parts by weight based on 100 parts by weight of the epoxy resin.
경화제는 방향족 아민, 지방족 아민, 퓨란수지, 탄산칼슘, 탈크, 흄드 실리카를 포함한다. 본 발명에서 경화제는 방향족 아민과 지방족 아민이 함께 함유된다. 이와 같이 방향족 아민과 지방족 아민을 경화제의 주성분으로 이용함으로써 화학적 안정성 및 내식성이 우수하고, 높은 접착력과 강도를 갖는다. Curing agents include aromatic amines, aliphatic amines, furan resins, calcium carbonate, talc, and fumed silica. In the present invention, the curing agent contains an aromatic amine and an aliphatic amine together. As described above, aromatic amine and aliphatic amine are used as a main component of a curing agent, so that they have excellent chemical stability and corrosion resistance, and have high adhesive strength and strength.
방향족 아민으로 메타페닐렌디아민(Metaphenylenediamine:MPD), 디아미노디페닐메탄(Diaminodiphenylmethane:DDM) 및 디아미노디페닐설폰(Diaminodiphenysulphone:DDS)으로 이루어진 군에서 선택된 하나 이상일 수 있다. 바람직하게 방향족 아민으로 디아미노디페닐메탄을 이용할 수 있다. The aromatic amine may be at least one selected from the group consisting of metaphenylenediamine (MPD), diaminodiphenylmethane (DDM), and diaminodiphenylsulfone (DDS). Diaminodiphenylmethane can preferably be used as the aromatic amine.

Diethylene triamine is preferably used as the aliphatic amine.
상기 지방족 아민은 방향족 아민 100중량부에 대하여 10 내지 20중량부가 첨가된다. The aliphatic amine is added in an amount of 10 to 20 parts by weight based on 100 parts by weight of the aromatic amine.
지방족 아민과 방향족 아민을 더한 양은 코팅 조성물 전체 중량에서 15 내지 35중량%의 비율로 함유된다. 상기 범위 미만으로 함유시 적절한 경화효과를 부여할 수 없고, 상기 범위를 초과하여 함유하는 경우에는 과도한 경화로 인하여 코팅막의 경도가 지나치게 높아지는 문제점이 있게 되므로 상기 범위 내에서 적용되는 표면에 따라 적절하게 사용하도록 한다.The amount of the aliphatic amine and the aromatic amine added is in the range of 15 to 35% by weight based on the total weight of the coating composition. If it is contained in an amount less than the above range, an appropriate hardening effect can not be given. If it exceeds the above range, there is a problem that the hardness of the coating film becomes excessively high due to excessive curing. Therefore, .
퓨란수지는 점결제 및 경화반응 촉진제로서 기능을 갖는다. 퓨란수지는 코팅막의 경도를 높인다. 퓨란수지(furan resin)는 퓨란 고리를 함유하는 수지로, 기름, 산, 알칼리, 용제에 대해서 내구력이 뛰어난 성질을 나타내고 에폭시 수지와 함께 사용될 경우 에폭시수지의 접착성, 변형에 뛰어난 특성을 부여한다. 퓨란수지로 테트라하이드로퓨란(Tetrahydrofuran)을 이용할 수 있다. 퓨란수지는 방향족 아민 100중량부에 대하여 60 내지 90중량부가 첨가된다. The furan resin has a function as a viscosity promoting and curing reaction promoter. The furan resin increases the hardness of the coating film. Furan resin is a resin containing furan ring and exhibits excellent durability against oils, acids, alkalis and solvents, and when used together with an epoxy resin, gives excellent properties to the adhesiveness and deformation of epoxy resin. Tetrahydrofuran may be used as the furan resin. The furan resin is added in an amount of 60 to 90 parts by weight based on 100 parts by weight of the aromatic amine.
탄산칼슘은 규사와 함께 내마모도, 강도, 경도, 표면접착력을 증진시키기 위해 사용된다. 탄산칼슘은 방향족 아민 100중량부에 대하여 60 내지 80중량부가 첨가된다. Calcium carbonate is used together with silica to improve abrasion resistance, strength, hardness and surface adhesion. Calcium carbonate is added in an amount of 60 to 80 parts by weight based on 100 parts by weight of the aromatic amine.
탈크 및 흄드 실리카는 상술한 주제의 경우와 같이 경화제에도 함유된다. 탈크는 방향족 아민 100중량부에 대하여 30 내지 50중량부가 첨가되고, 흄드 실리카는 방향족 아민 100중량부에 대하여 5 내지 15중량부가 첨가된다. Talc and fumed silica are also included in the curing agent as in the case of the above-mentioned subject. The talc is added in an amount of 30 to 50 parts by weight based on 100 parts by weight of the aromatic amine, and the fumed silica is added in an amount of 5 to 15 parts by weight based on 100 parts by weight of the aromatic amine.
한편, 경화제에는 안료가 더 추가될 수 있다. 이 경우 방향족 아민 100중량부에 대하여 안료 5 내지 10중량부가 첨가된다. 안료는 통상적으로 에폭시계 도료에 사용되는 것이면 특별히 한정되지 않는다. 적절한 안료의 예로, 황색 산화철 및 적색 산화철, 프탈로시아닌 등을 들 수 있다. On the other hand, pigments may be added to the curing agent. In this case, 5 to 10 parts by weight of the pigment is added to 100 parts by weight of the aromatic amine. The pigment is not particularly limited as long as it is usually used for an epoxy-based paint. Examples of suitable pigments include yellow iron oxide and red iron oxide, phthalocyanine and the like.

When the mixing ratio of the base and the curing agent is in the above range, a coating film which forms a strong bond with the surface of a structure made of various materials can be formed, and excellent chemical resistance, water resistance and corrosion resistance can be exhibited.
