Hereinafter, preferred embodiments of the present invention will be described in detail. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout.
본 발명에 따른 아크릴 폴리올 수지 도료 조성물은 아크릴 폴리올 수지 40∼60중량부, 체질안료 10∼15중량부, 폴리아미드 왁스 디스퍼젼형 침강 방지제 1∼3중량부, 탄산칼슘 10∼20중량부, 폴리에틸렌 왁스 1∼5중량부, 에폭시 실란 1∼5중량부 및 유기용제 5∼15중량부를 포함한다. The acrylic polyol resin coating composition according to the present invention comprises 40 to 60 parts by weight of an acrylic polyol resin, 10 to 15 parts by weight of an extender pigment, 1 to 3 parts by weight of a polyamide wax dispersion type anti-settling agent, 10 to 20 parts by weight of calcium carbonate, 1 to 5 parts by weight of a wax, 1 to 5 parts by weight of an epoxy silane, and 5 to 15 parts by weight of an organic solvent.
여기서, 폴리올 수지 도료 조성물을 파형강관에 도료하기 위해서 폴리이소시아네이트 80∼90중량부, 에스테르계 용제 5∼10중량부 및 아세테이트계 용제 5∼10중량부를 포함하는 경화제 혼합물을 더 혼합할 수 있다.
Here, in order to coat the polyol resin coating composition on the corrugated steel pipe, a curing agent mixture comprising 80 to 90 parts by weight of polyisocyanate, 5 to 10 parts by weight of ester solvent and 5 to 10 parts by weight of acetate solvent may be further mixed.
본 발명에서 아크릴 폴리올 수지에 사용되는 원료는 메틸메타아크릴레이트 25∼35중량부, 하이드록시 에틸 메타아크릴레이트 10∼15중량부, 스티렌모노머 5∼10중량부 및 부틸메타아크릴레이트 10∼15중량부를 포함한다.
In the present invention, the starting material used for the acrylic polyol resin is 25 to 35 parts by weight of methyl methacrylate, 10 to 15 parts by weight of hydroxyethyl methacrylate, 5 to 10 parts by weight of styrene monomer and 10 to 15 parts by weight of butyl methacrylate .
본 발명에서 체질안료는 다원화학의 TALC SP3000 제품으로 10~15중량부를 사용하는 것이 바람직하며, 활석으로 이루어진다. 또한, 체질안료는 매우 연질이고, 촉감이 매끄러워 비누와 같은 지방감을 주고, 물이나 유기질 용액에 의한 팽윤성이 없고, 이온교환능도 거의 없고, 화학적으로 매우 안정하다.
In the present invention, the extender pigment is preferably TALC SP3000 manufactured by Daiwon Chemical Co., and it is preferable to use 10-15 parts by weight of talc. In addition, the extender pigment is very soft, smooth and gives a soap-like fat feeling, has no swelling by water or organic solution, has almost no ion exchange ability, and is chemically very stable.
본 발명에서 폴리아미드 왁스 디스퍼젼형 침강방지제는 미국 킹인더스트리의 DISPARLON 6900-20X 제품으로 1~3중량부 사용하는 것이 바람직하며, 침강방지와 흐름성방지 역할을 한다. 여기서, 폴리아미드 왁스 디스퍼젼형 침강방지제를 1중량부 미만으로 사용하는 경우 조성물을 도장시 조성물이 밑으로 흐르는 문제와 조성물의 저장기간 동안 안료가 침강하는 문제가 발생한다.
In the present invention, the polyamide wax dispersion-type anti-settling agent is preferably used in an amount of 1 to 3 parts by weight as DISPARLON 6900-20X of King Industries, USA, and serves to prevent sedimentation and prevent flow. Here, when the polyamide wax dispersion-type anti-settling agent is used in an amount of less than 1 part by weight, there is a problem that the composition flows downward during coating and that the pigment precipitates during the storage period of the composition.
본 발명에서 충전제로 사용하는 탄산칼슘은 10~20중량부를 사용하는 것이 바람직하다. 여기서, 탄산칼슘이 20중량부를 초과하는 경우 도막의 기계적 물성이 저하되는 문제가 발생한다.
The calcium carbonate used as a filler in the present invention is preferably used in an amount of 10 to 20 parts by weight. Here, when the amount of the calcium carbonate exceeds 20 parts by weight, the mechanical properties of the coating film are deteriorated.
본 발명에서 사용하는 폴리에틸렌 왁스는 Shamrock사의 Shamrock S 381N1제품을 사용하며, 폴리에틸렌 왁스는 1~5중량부를 사용하는 것이 바람직하다. 여기서, 폴리에틸렌 왁스가 5중량부를 초과하여 사용하는 경우 도막의 용제성 및 내화학성이 저하되는 문제가 발생한다.
The polyethylene wax used in the present invention is preferably a Shamrock S 381N1 product manufactured by Shamrock, and 1 to 5 parts by weight of a polyethylene wax is preferably used. Here, when the polyethylene wax is used in an amount exceeding 5 parts by weight, there arises a problem that the solvent resistance and chemical resistance of the coating film are lowered.
한편, 본 발명에서 소재와의 부착성을 높이기 위해 에폭시 실란을 도입하였다. 실란은 에스터 실란, 비닐실란, 메타크릴옥시 실란, 에폭시 실란, 아미노 실란, 우레이도(ureidos) 실란이 포함될 수 있다. 특히 에폭시 실란은 감마-글리시독시프로필트리메톡시 실란, 베타-에폭시씨클로헥실에틸트리메톡시 실란으로 이루어진 군에서 하나를 선택하여 사용하며 소재와의 높은 부착성이 생긴다.On the other hand, in the present invention, epoxy silane was introduced in order to improve the adhesion to the material. The silane may include ester silane, vinyl silane, methacryloxy silane, epoxy silane, aminosilane, ureidos silane. Particularly, the epoxy silane is selected from the group consisting of gamma-glycidoxypropyltrimethoxysilane and beta-epoxycyclohexylethyltrimethoxysilane, and high adhesion with the material is obtained.
또한, 에폭시 실란은 SILQUEST사의 A-187 제품으로 1∼5중량부 사용하는 것이 바람직하고, 에폭시기가 있어 가교에 참여함으로써 더욱 좋은 결합을 얻을 수 있으며, 내수성 및 내약품성을 좋게 한다. 또한, 무황변타입으로 에폭시의 단점을 보완하였다. 여기서, 에폭시 실란은 1∼5중량부를 사용하는 것이 바람직하며, 1중량부 미만으로 사용할 경우 도막의 부착성이 저하되는 문제점이 발생한다.
The epoxy silane is preferably used in an amount of 1 to 5 parts by weight as an A-187 product of SILQUEST, and it has an epoxy group and can participate in crosslinking to obtain a better bond and improve water resistance and chemical resistance. In addition, the non-yellowing type compensates for the disadvantages of epoxy. The epoxy silane is preferably used in an amount of 1 to 5 parts by weight, and when it is used in an amount of less than 1 part by weight, adhesion of the coating film is deteriorated.
본 발명에서 유기용제는 케톤류와 방향족계 탄화수소를 사용하며, 5∼15중량부를 사용하는 것이 바람직하다. 여기서, 케톤류는 상기 아크릴 폴리올 수지를 잘 녹이는 진용제로 수지의 점도를 낮춰 조성물의 다른 성분들과 잘 섞이도록 하는 역할을 하며, 방향족계 탄화수소는 케톤류의 진용제를 보조하는 값이 싼 보조용제이다. 여기서, 유기용제를 5중량부 미만으로 사용하는 경우 조성물이 잘 섞이지 않는 문제점이 발생한다.
In the present invention, ketones and aromatic hydrocarbons are used as the organic solvent, and it is preferable to use 5 to 15 parts by weight. Here, the ketone serves to dissolve the acrylic polyol resin well and to lower the viscosity of the resin to be mixed with other components of the composition. The aromatic hydrocarbon is a low-cost auxiliary solvent that assists the propellant of ketones. Here, when the organic solvent is used in an amount of less than 5 parts by weight, there arises a problem that the composition is not well mixed.
본 발명에서 폴리이소시아네이트는 Aliphatic Polyisosianates의 타입의 Bayer사(독일)의 Desmosdur -n3300을 사용하며, 80∼90중량부를 사용하는 것이 바람직하다. 여기서, 폴리이소시아네이트를 80중량부 미만으로 사용하는 경우 경화제의 점도가 너무 낮아지는 경향이 발생하고, 90중량부 보다 많이 사용하는 경우 점도가 높아 사용하기 어려운 문제점이 발생한다.
In the present invention, Desmosdur-n3300 of Bayer (Germany) of the type of Aliphatic Polyisocyanates is used as the polyisocyanate, preferably 80 to 90 parts by weight. Here, when the polyisocyanate is used in an amount of less than 80 parts by weight, the viscosity of the curing agent tends to be too low. When the polyisocyanate is used in an amount of more than 90 parts by weight, the viscosity is too high.
본 발명에서 에스테르계 용제는 폴리이소시아네이트의 알맞은 희석을 위해 사용되며, 에스테르계 용제는 5∼10중량부를 사용하는 것이 바람직하다.
In the present invention, the ester solvent is used for proper dilution of the polyisocyanate, and the ester solvent is preferably used in an amount of 5 to 10 parts by weight.
본 발명에서 Ethyle Acetate 및 Butyl Acetate 같은 에스테르계 용제는 폴리이소시아네이트의 희석기능과 더불어 착향의 기능을 위해 사용되며, 아세테이트계 용제는 5∼10중량부를 사용하는 것이 바람직하다.
In the present invention, ester solvents such as Ethyle Acetate and Butyl Acetate are used for the function of dilution with polyisocyanate as well as for the function of anion, and it is preferable to use 5 to 10 parts by weight of the acetate solvent.
