Abstract
Description
본 발명은 PVC 프로파일용 불소 피막 조성물에 관한 것으로서, 다양한 색상의 수용성 불소 도료를 도장함으로써 PVC의 변색을 방지하고, 다양한 색상을 부여하며, 유기용제를 사용하지 않아 PVC 재질을 손상시키지 않는 수용성 불소 도료 조성물에 관한 것이다.The present invention relates to a fluorine coating composition for PVC profiles, by coating a water-soluble fluorine paint of various colors to prevent discoloration of PVC, impart a variety of colors, do not damage the PVC material by not using organic solvents It relates to a composition.
창과 문으로 총칭되는 창호는 일반적으로 목재, 알루미늄, 폴리비닐클로라이드(이하 PVC)등 여러 가지로 사용되고 있다. 그 중 PVC 창호는 목재, 알루미늄 재질에 비하여 단열성, 방음성, 수밀성 등이 우수하여 그 적용이 확대되고 있으나 건물 외부 창호로 노출되는 PVC 창호 프레임은 PVC 내에 존재하는 탄소와 염소 구조가 자외선에 대해서 쉽게 파괴되기 때문에 내후성 및 내구성능이 떨어져 다양한 방법으로 PVC 창호의 내후성 및 내구성 보완이 이루어지고 있다.Windows and doors, collectively referred to as windows and doors, are generally used in various ways such as wood, aluminum and polyvinyl chloride (PVC). Among them, PVC windows and windows are superior in insulation, sound insulation, and watertightness compared to wood and aluminum materials, but their application is expanding.However, the PVC windows and door frames exposed to windows outside the building easily destroy carbon and chlorine structures in PVC against UV rays. As weather resistance and durability are poor, the weather resistance and durability of PVC windows and doors are complemented in various ways.
PVC 창호의 내후성을 보완하기 위해 창호를 자연광으로부터 차단하는 방법으로는 4가지가 있다.To supplement the weather resistance of PVC windows, there are four ways to block windows from natural light.
첫째, 내후성이 우수한 안료를 적용한 방법이 있다. 이는 PVC 압출 시 내후성이 우수한 안료가 PVC 표면에 배열됨으로써PVC의 내후성을 보완하지만 안료와 PVC의 부조화성 등으로 인하여 균일한 사출이 어려워 창호가 가져야 할 물리적 특성에 악영향을 끼칠 수 있다.First, there is a method of applying a pigment excellent in weatherability. This is because the pigments having excellent weather resistance during PVC extrusion are arranged on the surface of the PVC to compensate for the weather resistance of the PVC, but due to the incompatibility of the pigment and PVC, uniform injection is difficult, which may adversely affect the physical characteristics that the windows should have.
둘째, 내후성이 우수한 재질의 폴리에틸렌(PE), 폴리프로필렌(PP), 아크릴로니트릴-스틸렌-아크릴레이트 고무 공중합체 수지(ASA)를 외부와 접촉하는 PVC 창호면과 이중으로 공압출하는 방법이다. 이는 두 가지 다른 플라스틱으로 구성된 창호이기 때문에 오랜시간 외부 온도와 압력이 가해질 경우 창호 접촉면에 틈이 생겨 분리가 될 가능성이 있다.Secondly, polyethylene (PE), polypropylene (PP), and acrylonitrile-styrene-acrylate rubber copolymer resin (ASA) having excellent weather resistance are co-extruded with a PVC window surface in contact with the outside. Since this is a window made of two different plastics, it is likely that a window will open and become detached if the external temperature and pressure are applied for a long time.
셋째, 고내후성 라미네이트 필름을 부착하는 방법이 있다. 이는 기존의 내후성이 열악하여 내부용으로만 사용되는 라미필름을 고내후성 필름으로 전환하여 PVC 창호에 랩핑하는 방법이다. 랩핑의 방법의 기존의 내부용처럼 접착제에 의해 시트를 부착하기 때문에 굴곡진 구조를 갖는 창호에 적용 시 시트 접착력이 떨어지고, 외부의 온도, 습도의 영향으로 시트와 PVC 창호의 부착성을 저하되어 PVC 창호로부터 분리된다.Third, there is a method of attaching a high weatherability laminate film. This is a method of laminating a PVC window by converting a lamination film, which is used only for internal use due to poor weather resistance, to a high weather resistant film. Since the sheet is attached by an adhesive like the conventional interior of the lapping method, the sheet adhesive strength is lowered when applied to a curved window, and the adhesion between the sheet and the PVC window is reduced by the influence of external temperature and humidity. It is separated from the window.
넷째, 외부로 노출되는 PVC 창호를 도료로 도장하는 방법이 있다. 이는 도료와 PVC창호가 화학적, 물리적으로 반응하여 부착을 형성하기 때문에 오랜 시간이 지나도 PVC 창호에서 이탈이 되거나 하지 않고 PVC 창호를 보호 할 수 있다.Fourth, there is a method of painting PVC windows and doors exposed to the outside with paint. This is because paint and PVC windows react with each other chemically and physically to form adhesion, so it is possible to protect PVC windows without leaving the PVC windows after a long time.
종래 사용하여온 PVC 창호용 불소도료로는 대한민국 공개특허 제2003-0057963호의 불소 수지와 아크릴 공중합 수지를 이용하여 제조된 용제형 도료가 있 다. 이 용제형 불소 수지 도료는 도료 내 포함된 방향족 탄화수소류, 아세테이트류, 케톤류의 용제에 의해 PVC 소재를 용해하면서 도막을 형성하여 용제의 용해와 도막의 형성이 동시에 이루어지며, PVC 표면에 형성된 도막은 PVC 소재와 우수한 밀착력을 형성하고, 불소 도막이 PVC창호를 자연광으로부터 차단함으로써 PVC 창호의 내구성을 증진시킨다. Conventionally used fluorine paint for PVC windows and doors is a solvent-type paint prepared by using a fluorine resin and an acrylic copolymer resin of Republic of Korea Patent Publication No. 2003-0057963. This solvent-type fluororesin paint dissolves PVC material by the solvent of aromatic hydrocarbons, acetates, and ketones contained in the paint, and forms a coating film to simultaneously dissolve the solvent and form the coating film. It forms excellent adhesion with PVC material and enhances durability of PVC windows by blocking fluorine coating windows from natural light.
그러나 이때 불소 도료에 포함된 용제로 인하여 용해 융착된 PVC 표면은 용해된 PVC의 물질 변이로 인하여 PVC 즉, 비닐 클로라이드가 지녀야할 인장력, 저온 충격성등 기계적 물성이 영향을 받게 된다. 또한 용제형 도료의 경화 반응인 폴리이소시아네이트와 폴리올의 반응이 느리게 반응하여 코팅이 완료되는데 48시간이상의 시간이 소요되어 창호의 도장 생산성이 저하 되는 문제점이 있었다.However, at this time, the surface of PVC melted and fused due to the solvent contained in the fluorine paint is affected by mechanical properties such as tensile strength, low temperature impact properties of PVC, ie, vinyl chloride, due to material variation of the dissolved PVC. In addition, the reaction between the polyisocyanate and the polyol, which is a curing reaction of the solvent type paint, reacts slowly, and thus, coating takes about 48 hours to complete the coating.
본 발명은 수용성 불소 도료에 관한 것으로, 기존의 용제도료로 인하여 창호의 폴리비닐클로라이드 표면이 용해되는 문제를 해소하기 위하여, 환경 친화적으로 물을 희석제로 사용하며 폴리비닐클로라이드의 물성을 저하시키는 용제를 사용하지 않고 소재와 안정적으로 부착함으로써 폴리비닐클로라이드(PVC) 창호의 물성을 그대로 유지하여 우수한 인장력, 강성, 저온 충격성을 갖게 하는 PVC 창호용 수용성 불소 도료 조성물을 제공하고자 한다.The present invention relates to a water-soluble fluorine paint, in order to solve the problem of dissolving the surface of the polyvinyl chloride of windows and doors due to conventional solvents, using water as a diluent to reduce the properties of polyvinyl chloride environmentally friendly The present invention is to provide a water-soluble fluorine coating composition for PVC windows and doors by stably adhering to the material without using them to maintain the physical properties of the polyvinyl chloride (PVC) window as it has excellent tensile strength, rigidity, low temperature impact properties.
본 발명은 폴리비닐클로라이드(이하, PVC라 함) 재질의 창호에 적용이 가능한 불소 피막 조성물에 관한 것으로서, 종래 안정제로 사용되는 TiO2로 인하여 백색의 단색으로 제조되던 PVC 창호를 다양한 색상으로 제조하기 위한 도료 조성물에 관한 것이다. The present invention relates to a fluorine coating composition that can be applied to windows of polyvinyl chloride (hereinafter referred to as PVC), and to manufacture PVC windows made of a single color of white due to TiO 2 used as a stabilizer in various colors. It relates to a coating composition for.
또한 본 발명은 PVC자체의 물성을 저하시키지 않도록 수용성으로 제조되어 외부 기후 환경에 열악한 PVC 소재의 고내후성 보완하고 다양한 색상을 부여하기 위한 자연 건조형 수용성 불소 도료 조성물에 관한 것이다. In addition, the present invention relates to a naturally-drying water-soluble fluorine coating composition to be made of water-soluble so as not to degrade the physical properties of the PVC itself to supplement the high weather resistance of the PVC material poor in the external climatic environment and to give a variety of colors.
보다 구체적으로, 본 발명은 수용성 폴리플루오로 중합물 20 ~ 50 중량%, 하이드록시기를 갖는 수용성 폴리카보네이트폴리우레탄 디스퍼젼 10 ~ 40 중량%, 폴 리디메틸실록산계 표면처리제로 코팅된 변성 흄드 실리카 또는 아크릴 비드에서 선택되는 표면 첨가제 1 ~ 5 중량%, 유기 또는 무기 안료 15 ~ 30 중량%, 물 2 ~ 10 중량%, 수용성 용제 5 ~ 15 중량%를 포함하는 수용성 불소 도료 조성물을 제공한다. 또한 상기 도료 조성물에 이온성 계면활성제 0.01 ~ 1 중량%, 소포제 0.1 ~ 2.0 중량%를 더 포함할 수 있다.More specifically, the present invention is a modified fumed silica or acrylic coated with 20 to 50% by weight of a water-soluble polyfluoropolymer, 10 to 40% by weight of a water-soluble polycarbonate polyurethane dispersion having a hydroxy group, and a polydimethylsiloxane-based surface treatment agent. It provides a water-soluble fluorine coating composition comprising 1 to 5% by weight of the surface additive selected from the beads, 15 to 30% by weight of organic or inorganic pigments, 2 to 10% by weight of water, and 5 to 15% by weight of a water-soluble solvent. In addition, the coating composition may further include 0.01 to 1% by weight of ionic surfactant, 0.1 to 2.0% by weight of the antifoaming agent.
본 발명에 따른 수용성 불소 도료 조성물은 폴리비닐클로라이드(PVC) 창호에 스프레이 도장 또는 진공흡입 도장을 진행하여 피도물을 도포한 후 30분간 50℃에서 건조하거나 혹은 자연 환경상(상온)에서 건조하여 도막을 형성한다.The water-soluble fluorine coating composition according to the present invention is applied to the polyvinyl chloride (PVC) windows by spray coating or vacuum suction coating, and then coated at 30 ° C. for 30 minutes or dried in a natural environment (room temperature) to form a coating film. do.
이하는 본 발명의 구성요소에 대하여 보다 구체적으로 설명한다.Hereinafter, the components of the present invention will be described in more detail.
고내후성이 우수한 폴리비닐리덴 플루오라이드(PVDF) 불소 수지는 230℃고온에서 용융하여 도막을 형성 한다. 본 발명의 상기 수용성 폴리플루오로 중합물은 고온에서만 적용되는 PVDF를 낮은 온도에서도 경화 및 건조가 가능하게 하기 위하여 플루오로화에틸렌과 알킬비닐에테르를 공중합하고, 수용액상에서 안정한 상태를 유지하기 위하여 말단에 옥시에틸렌알킬에테르를 생성시켜 수용액 상에서도 안정한 에멀젼 상태를 유지하는 수용성 불소 수지를 이용한다. Polyvinylidene fluoride (PVDF) fluorine resin having excellent weather resistance is melted at 230 ° C. high temperature to form a coating film. The water-soluble polyfluoropolymer of the present invention copolymerizes fluorinated ethylene and alkylvinyl ether in order to enable curing and drying of PVDF, which is applied only at high temperature, even at low temperature, and oxy at the end to maintain a stable state in aqueous solution. A water-soluble fluororesin which produces ethylene alkyl ether and maintains a stable emulsion state even in aqueous solution is used.
상기 수용성 폴리플루오로 중합물은 수분산, 수용성 중합체 혼합물을 통칭하는 것으로서, 수평균 분자량이 5000 ~ 20,000이고, 고형분 함량이 40 ~ 60 %이며, 0~40℃의 상온에서도 필름을 형성하는 것을 특징으로 하는 수용성 불소수지를 사용한다. 수평균 분자량이 5000미만일 경우 도막의 체인이 강하지 못하여 도막의 내충격성이 떨어지고, 20,000을 초과하는 경우 점도가 높아 도료배합 내 다른 원료와 혼합하는데 어려움이 있다. 이러한 수용성 폴리플루오로 중합물의 예로는, 아사히 글라스사의 루미플론(LUMIFLON) 중 FE4300이 있다. The water-soluble polyfluoropolymer is a generic term for water dispersion and water-soluble polymer mixture, and has a number average molecular weight of 5000 to 20,000, a solid content of 40 to 60%, and forms a film at room temperature of 0 to 40 ° C. Water-soluble fluorocarbon resin is used. If the number average molecular weight is less than 5000, the chain of the coating film is not strong, the impact resistance of the coating film is low, and if it exceeds 20,000, it is difficult to mix with other raw materials in the paint formulation because of the high viscosity. An example of such a water-soluble polyfluoropolymer is FE4300 in LUMIFLON from Asahi Glass.
상기 수용성 폴리플루오로 중합물은 전체 조성물 중 20 ~ 50중량%로 사용되며, 20중량% 미만으로 사용되는 경우에는 내후성이 열세하며, 50중량%를 초과하는 경우 내후성은 우수하나 PVC 창호와의 부착성이 열세하다.The water-soluble polyfluoropolymer is used in 20 to 50% by weight of the total composition, when used in less than 20% by weight is inferior in weather resistance, when it exceeds 50% by weight is excellent in weather resistance but adhesion to PVC windows and doors This is thirteen.
상기 하이드록시기를 갖는 수용성 폴리카보네이트폴리우레탄 디스퍼젼은 폴리우레탄 수지 내에 카보네이트기를 갖는 화합물을 의미하는 것으로, 수평균 분자량이 5000 ~ 30000이고, 연신율이 300 ~ 800%인 것을 사용한다. 수지의 연신률이 상기 범위 보다 낮을 경우 도막의 경도가 높아져 충격성에 열세하며, 높을 경우 점성이 낮아 내오염성, 내스크래치, 내마모성 등의 물성이 저하될 수 있다. 또한, 수평균 분자량이 5000 미만인 경우 분자간 결합력이 강하지 못하여 충격성, 인장강도 등이 떨어지고, 30000을 초과하는 경우 점도가 너무 높아 도료내 다른 원료와의 혼합이 어렵다. 예를 들면, 람베르티사의 PU 71, PU 61, PU 51, 알버딩크사의 PU9800_APU10610, U9800, U9500 등이 사용가능하나 이에 제한되는 것은 아니다. The water-soluble polycarbonate polyurethane dispersion having a hydroxyl group means a compound having a carbonate group in the polyurethane resin, and a number average molecular weight of 5000 to 30000 and an elongation of 300 to 800% are used. When the elongation of the resin is lower than the above range, the hardness of the coating film becomes high and is inferior to impact resistance. When the elongation of the resin is high, the viscosity may be low, so that physical properties such as stain resistance, scratch resistance, and wear resistance may be lowered. In addition, when the number average molecular weight is less than 5000, the intermolecular bonding strength is not strong, impact resistance, tensile strength, etc. are lowered, and when the number average molecular weight exceeds 30000, the viscosity is too high, it is difficult to mix with other raw materials in the paint. For example, Lamberti's PU 71, PU 61, PU 51, Alberding's PU9800_APU10610, U9800, U9500 and the like can be used, but are not limited thereto.
상기 폴리카보네이트 폴리우레탄 디스퍼젼은 10 ~ 40중량%로 사용하며, 10 중량% 미만으로 사용되는 경우에는 PVC 창호와의 부착성이 열세이고, 40중량%를 초과하는 경우에는 내후성, 내약품성이 일반 도료와 동일한 물성을 가지므로 고내후성, 내약품성을 요구하는 고기능성 창호에는 바람직하지 않다.The polycarbonate polyurethane dispersion is used at 10 to 40% by weight, and when used at less than 10% by weight, the adhesion with PVC windows is inferior, and when it exceeds 40% by weight, weather resistance and chemical resistance are general. Since it has the same physical properties as paint, it is not preferable for high functional windows and doors requiring high weather resistance and chemical resistance.
본 발명의 PVC 창호용 도료는 외부로 노출 되는 부위이기 때문에 시각적인 효과를 위하여 60˚글로스미터 광택 기준으로 20 ~ 40˚의 광택 관리가 요구 된다. 광택의 정도는 도막 면의 거칠기, 용매 증발 및 필름 수축의 형태와 도장 공정, 온습도 조건, 용제 및 첨가제의 조성 등에 의해 영향을 받는데 가장 우선적으로는 도료 내부에 포함된 첨가제의 도막표면 내 상승으로 형성되는 도막의 거칠기가 일차적인 원인이다. 도막 표면에 상승되어 도막의 거칠기를 형성하는 물질로는 일반적으로 실리카, 탈크, 칼슘 카보네이트 등이 있으며 도장 후 도막 표면에 상승하여 도막을 형성 한 후 조사 빛이 확산 및 산란, 반사되면서 광택이 높고 낮음이 결정 된다.Since the paint for PVC windows and doors of the present invention is a part exposed to the outside, a gloss management of 20 to 40 ° is required on a 60 ° gloss gloss standard for visual effects. The degree of gloss is affected by the roughness of the coating surface, the form of solvent evaporation and film shrinkage, the painting process, the temperature and humidity conditions, the composition of the solvent and the additive, and most of all, it is formed by the rising of the additive in the coating surface. The roughness of the coated film is a primary cause. The materials which rise on the surface of the coating film to form the roughness of the coating film generally include silica, talc, calcium carbonate, etc., after rising to the surface of the coating film after coating to form a coating film, the irradiation light is diffused, scattered, reflected, and high in gloss. This is determined.
본 발명에서는 수용성 플루오로 수지에 영향을 받지 않고, 내후성에 영향을 주지 않기 위하여, 폴리디메틸실록산계 표면처리제로 처리된 변성 흄드 실리카 또는 아크릴 비드, 폴리에틸렌왁스, 폴리프로필렌 왁스를 1 ~ 5 중량%를 사용한다. 그 사용량이 1중량 % 미만인 경우 소광 효과가 없으며, 5중량% 를 초과하는 경우 광택이 과하게 소실되어 20˚이하의 광택을 갖는다. 상기 함량 범위로 사용하는 경우 60˚글로스미터 광택 기준으로 20 ~ 40˚의 광택을 유지할 수 있다.In the present invention, 1 to 5% by weight of modified fumed silica or acrylic beads, polyethylene wax, and polypropylene wax treated with a polydimethylsiloxane-based surface treatment agent is not affected by the water-soluble fluororesin and does not affect weather resistance. use. If the amount is less than 1% by weight, there is no quenching effect. If it is more than 5% by weight, the gloss is excessively lost to have a gloss of 20 ° or less. When used in the content range can maintain a gloss of 20 to 40 ° on the basis of 60 ° gloss gloss.
상기 변성 흄드실리카의 예로는 C308, C803 등이 있으며, 상기 아크릴비드는 데구사의 S50C, S100, S150등이 있으며 이들에 제한되는 것은 아니다.Examples of the modified fumed silica include C308, C803, and the like, and the acrylic beads include, but are not limited to, S50C, S100, S150, and the like.
또한 상기 표면개질제의 평균입경은 2 ~ 6㎛인 것이 바람직하며, 6㎛를 초과하는 경우 입자가 커지면 산란, 확산 되는 빛의 양이 많아져서 광택이 낮아진다.In addition, it is preferable that the average particle diameter of the surface modifier is 2 to 6㎛, and when the particle size is larger than 6㎛, the amount of light scattered and diffused increases, resulting in low gloss.
본 발명에서 상기 이온성 계면활성제는 수용성 계와 유용성계의 사용성을 개선하기 위해 여 사용되는 것으로, 소수성 성질이 강한 계면활성제를 사용하는 것이 기포가 생성되었다 쉽게 제거되므로 바람직하며, 예를 들면, BYK 케미칼사의 BYK 384, 333, 376 등이 사용 가능하며, 이들에 제한되는 것은 아니다 .그 함량은 전체 조성물 중 0.01 ~ 1 중량%로 사용한다. 0.01 중량% 미만으로 사용하는 경우 표면 개선 효과가 나타나지 않고, 1 중량%를 초과하는 경우에는 기포가 많이 발생하여 외관이 양호하지 않다. In the present invention, the ionic surfactant is used to improve the usability of the water-soluble and oil-soluble systems, and it is preferable to use a surfactant having a strong hydrophobic property because bubbles are easily removed and, for example, BYK Chemicals BYK 384, 333, 376 and the like are available, but are not limited to these. The content is used in 0.01 to 1% by weight of the total composition. If the amount is less than 0.01% by weight, no surface improvement effect is observed, and if it is more than 1% by weight, many bubbles are generated and the appearance is not good.
본 발명에서 사용되는 소포제는 도료의 표면 장력을 낮추게 하여 기포를 제거하는 효과를 발휘하는데 도료내 혼합되는 수용성 폴리플루오로 불소수지와 수용성 우레탄 디스퍼젼수지로 인하여 발생되는 다량의 기포를 기포를 제거하기 사용한다. 소포제로는 디메틸폴리실록산의 실리콘계 소포제와 비닐아크릴 코폴리머의 실리콘을 함유하지 않는 실리콘 프리타입의 소포제를 0.5 ~ 2 중량%로 사용한다. 그 사용량이 0.5 중량% 미만인 경우 도료 내 기포가 존재하여 도막 형성 중에 존재하는 기포로 인하여 이색현상 및 도막 형성 후에 외관에 기포자국이 남게 되어 외관을 양호하지 못하며, 2 중량%를 초과하는 경우에는 다량의 실리콘이 도료네 완전히 혼합되지 못하고 표면에 떠오른 낮은 표면 장력을 갖는 실리콘 소포제는 크레터링을 발생 시킬 수 있다. 예를 들면, BYK 케미사의 BYK021 , BYK028 , BYK024 등이 있으나 이에 제한되는 것은 아니다.The antifoaming agent used in the present invention lowers the surface tension of the paint to remove the air bubbles. The antifoaming agent removes a large amount of air bubbles generated by the water-soluble polyfluoro fluorine resin and the water-soluble urethane dispersion resin mixed in the paint. use. As the antifoaming agent, a silicone antifoaming agent of dimethylpolysiloxane and a silicone-free antifoaming agent containing no silicone of vinylacrylic copolymer are used at 0.5 to 2% by weight. If the amount is less than 0.5% by weight, bubbles in the paint are present, resulting in dichroic phenomena and bubble marks on the appearance after the formation of the coating film, resulting in poor appearance. The silicone antifoaming agent with low surface tension, which is not fully mixed with the silicone and floats on the surface, can cause the cruttering. For example, BYK021, BYK028, BYK024, etc., but are not limited to BYK Chem.
상기의 수용성 용제는 물과 혼합이 가능하고 PVC의 표면에 영향을 적게 주는 약용제로써 에틸셀루솔브, 부틸셀루솔부, 메틸카비톨, 에틸카비톨, 부틸카비톨에서 선택되는 어느 하나 이상의 글리콜류; 또는 에틸알콜, 메틸알콜, 부틸알콜, 이소부틸알콜에서 선택되는 어느 하나 이상의 알콜류;에서 선택되는 단독 또는 2종 이상의 혼합용제를 사용하며, 전체 피막 조성물에 대하여 5 ~ 15중량% 범위로 사용한 다. 그 사용량이 5중량% 미만인 경우에는 PVC 창호와 도막의 부착이 열세하며, 15중량%를 초과하는 경우에는 도막의 건조 중에 PVC 창호와 접촉시간이 길어져 PVC 창호 표면을 약하게 하여 저온 충격성을 저하 시킨다.The water-soluble solvent can be mixed with water and less affects the surface of the PVC as a medicinal solvent, any one or more glycols selected from ethyl cellulose solver, butyl cellulose sole, methyl carbitol, ethyl carbitol, butyl carbitol; Or any one or more alcohols selected from ethyl alcohol, methyl alcohol, butyl alcohol and isobutyl alcohol; used alone or in combination of two or more kinds thereof, and used in a range of 5 to 15% by weight based on the total coating composition. If the amount is less than 5% by weight, the adhesion of PVC windows and coatings is inferior, and if it is more than 15% by weight, the contact time is increased with the PVC windows and doors during drying of the coating film, which weakens the surface of PVC windows and lowers the impact resistance at low temperatures.
본 발명의 도료 조성물 중 물은 2 ~ 10중량%를 사용하며, 그 사용량이 2중량% 미만이면 수용성 수지가 용제에 의해 영향을 받아 저장성이 불량하며, 10 중량%를 초과하는 경우 도료의 점도가 낮아 흐름이 발생하여 작업성이 저하된다.Water is used in the coating composition of the present invention 2 to 10% by weight, when the amount is less than 2% by weight of the water-soluble resin is affected by the solvent, poor storage properties, when the viscosity exceeds 10% by weight of the paint Low flow results in poor workability.
이밖에도 피막 조성물에 사용되는 기타의 첨가제 등이 포함될 수 있고 이러한 첨가의 함유 여부는 발명에 크게 영향을 미치지는 못한다.In addition, other additives and the like used in the coating composition may be included, and the inclusion of such addition does not significantly affect the invention.
상기한 바와 같이 본 발명에 사용된 수용성 플루오로 중합물을 포함한 수용성 도료를 PVC 창호에 도장할 경우 기존 용제형 도료가 갖는 단점인 저온충격성이 양호하고, 50℃에서 30분 건조 후에도 도료의 표면이 묻어나지 않아 창호의 도장 생산성이 향상되며, 불소 도료가 도장된 창호는 도장되지 않는 PVC 창호와 우레탄, 아크릴 도장된 창호 칼라창호 보다 우수한 내약품성과 우수한 내후성으로 창호의 내구성을 향상시키는 PVC 창호용 수용성 도료로 유용하다.As described above, when the water-soluble paint containing the water-soluble fluoropolymer used in the present invention is coated on the PVC window, the low temperature impact property, which is a disadvantage of the conventional solvent type paint, is good, and the surface of the paint remains even after drying at 50 ° C. for 30 minutes. The paint productivity of windows and doors is improved, and the windows and doors coated with fluorine paint are water-soluble paints for PVC windows and doors that improve durability of windows and doors with better chemical resistance and weather resistance than PVC windows and urethane and acrylic color windows.
