Description
본 발명은 수성 균열도료에 관한 것으로, 더 자세하게는 부분 알칼리화 폴리비닐 알코올 수지와, 가교결합형 옵셋 잉크 에멀젼 및 물을 주성분으로 하여 조성됨으로써, 종래의 유성 균열도료에 비하여 시공이 간편할 뿐만 아니라 독성이 없으면서도 균열 효과를 향상시킨 수성 균열도료에 관한 것이다.The present invention relates to an aqueous cracking coating, and more particularly, it is composed of a partially alkaline polyvinyl alcohol resin, a crosslinking offset ink emulsion, and water as a main component, thereby making construction easier and more toxic than conventional oily coatings. The present invention relates to an aqueous crack coating which improves the cracking effect without the absence.
도료는 각종 내·외장재의 표면을 보호하는 동시에 미관을 향상시키기 위한 것으로, 도료의 주성분은 도막 형성 성분인 전색제와 안료 성분으로 구성되는바, 안료는 도막에 색채를 부여하는 성분이며, 전색제는 안료 등을 분산시켜 도료에 유동성을 주는 투명도료에 해당한다.The paint is used to protect the surfaces of various interior and exterior materials and to improve aesthetics. The main component of the paint consists of a colorant and a pigment component, which is a coating film forming component, and the pigment is a component that gives color to the coating film. Corresponds to the transparent paint that gives liquidity to the paint by dispersing the back.
상기와 같은 도료는, 단순히 각종 내·외장재의 표면을 보호하는 동시에, 주위 환경과 어울리는 적합한 색상을 부여함으로써 내·외장재의 미관도 개선할 수 있도록 사용되어 왔으며, 과학 기술의 발전과 함께 생활 수준이 향상됨에 따라 단순히 내·외장재의 표면을 보호하고 색상을 부여하는 정도 이상의 역할을 수행할 수 있도록 다양한 기능성 도료가 개발되어 왔다.Such paints have been used to improve the aesthetics of interior and exterior materials by simply protecting the surfaces of various interior and exterior materials and by providing appropriate colors to match the surrounding environment. As improvements have been made, various functional paints have been developed to play a role of more than simply protecting and coloring the surface of interior and exterior materials.
그러나, 종래 대부분의 도료는 그 표면이 매끄럽게 마무리되며, 건조 후 표면에 균열이 발생하여서는 안 되나, 오히려 도막 표면에 균열을 발생시키고, 균열이 형성된 표면 상태를 미적으로 이용하는 도료가 개발되었는 바, 이를 균열도료(또는 크래킹 도료)라 한다.However, most conventional paints have smooth surfaces, and after drying, no cracks are generated on the surface. Rather, paints have been developed that generate cracks on the surface of the coating film and aesthetically use the surface state in which the cracks are formed. It is called crack paint (or cracking paint).
상기 균열도료는, 안료 분보다 수지 분을 적게 함유하도록 하여 용제가 도막으로부터 증발할 때 수지 분이 수축하면서 그 표면에 갈라지는 형상이 발생하도록 한 도료로서, 도막의 두께를 두껍게 도장하는 경우에는 갈라짐이 크고 많아지며, 얇게 하면 작고 적어진다.The crack coating contains less resin powder than the pigment powder, so that when the solvent evaporates from the coating film, the resin powder shrinks and forms a crack on its surface. When the coating film is thickly coated, the crack is large. The thinner it is, the smaller it becomes.
그리고, 상기 균열도료는, 그 도막 표면에 미적인 균열 무늬가 형성되고, 그러한 균열 무늬에 의해 우아한 인테리어적 장식 효과가 얻어지도록 하게 되는바, 실내 인테리어, 도자기류, 목재 가구류 등의 각종 공예품이나 외장재의 표면 장식에 사용되며, 일반도료에 비하여 도막 접착력, 내구성 등이 떨어지기 때문에 균열도료층 표면에는 투명도료가 피복되는 것이 일반적이다.In addition, the crack paint is formed to have an aesthetic crack pattern on the surface of the coating film, and to obtain an elegant interior decoration effect by such a crack pattern, so that various crafts and exterior materials such as indoor interior, ceramics, wooden furniture, etc. Since it is used for surface decoration, the coating film adhesion, durability, etc. are inferior to the general coating, it is common that the transparent coating is coated on the surface of the crack coating layer.
상기와 같은 균열도료 역시 사용되는 용제에 따라 유성 도료와 수성 도료로 구분되며, 일반 유성 도료와 마찬가지로 종래의 유성 균열도료 역시 제조할 때뿐만 아니라 사용시에도 반드시 벤졸류, 에스테르류, 케톤류 등이 대량 함유된 유기 용제로 희석시켜야 하기 때문에 환경오염 및 인체 건강에 극히 유해로 울뿐만 아니라, 생산 및 시공 단계에서 화재 위험성이 상존하게 된다.The above-mentioned crack paints are also divided into oil paints and water paints according to the solvents used. Like conventional oil paints, conventional oil paints also contain a large amount of benzols, esters, ketones, etc., as well as during the production. Due to the need for dilution with organic solvents, it is extremely harmful to environmental pollution and human health, as well as the risk of fire in the production and construction stages.
그리고, 유성 균열페인트로 도장하는 경우에는 반드시 일반 니트로셀루로즈 바니쉬(nitrocellulose varnish)로 하도를 실시한 후 그 하도 위에 균열도료를 칠하게 되는데, 이는, 균열도료 중의 유기 용제가 하도층의 니트로셀루로즈 바니쉬를 용해하게 되고, 균열도료보다 수축성이 큰 용해 니트로셀루로즈 바니쉬가 건조되는 과정에서 니트로셀루로즈 바니쉬의 수축력이 균열도료를 더욱 수축시키도록 함으로써 균열도료층에 균열이 발생하도록 하기 위해서이다.In addition, in the case of coating with oil-based crack paint, after coating is usually performed with nitrocellulose varnish, crack coating is applied on the coating under which the organic solvent in the crack coating is applied to the nitrocellulose varnish of the undercoat. This is to dissolve and to cause cracks in the crack coating layer by causing the shrinkage force of the nitrocellulose varnish to further shrink the crack coating in the process of drying the dissolved nitrocellulose varnish having greater shrinkage than the crack coating.
따라서, 건조 온도가 균열정도에 큰 영향을 미치게 되기 때문에 시공 온도가 비교적 높을 때에는 용제의 휘발이 너무 빨리 이루어져 균열을 형성시키기 어려우며, 휘발성과 용해성이 서로 다른 희석제를 사용하여 시공하게 되는 경우 균열 형성 효과도 일치하지 않게 되기 때문에 종래의 유성 균열도료는 그 시공이 어렵고, 균열 형성 제어도 어렵다.Therefore, the drying temperature has a great influence on the degree of cracking. Therefore, when the construction temperature is relatively high, the volatilization of the solvent is too fast, making it difficult to form cracks. In addition, since the conventional oil-based crack coating is difficult to install, it is difficult to control crack formation.
상기와 같은 유성 균열도료의 문제점을 해결할 수 있는 수성 균열도료가 국내 특허공보 73-107호에 개시되어 있으나, 이 균열도료 역시 그 성분 중에 포름알데히드가 함유되어 생산과 시공시 환경오염 및 인체 건강에 대한 유해성을 해소할 수가 없다.Aqueous cracking paints are disclosed in Korean Patent Publication No. 73-107, which can solve the above problems of oily cracking paints. However, these cracking paints also contain formaldehyde in its composition, which is harmful to environmental pollution and human health during production and construction. It can not solve the hazards.
본 발명은 종래의 유성 및 수성 균열도료가 가지고 있는 제반 문제점들을 해결하기 위하여 창안된 것으로, 제조 및 시공시 환경오염이나 인체에 대한 위해성이 없으면서도 누구나 손쉽게 시공이 가능한 수성 균열도료를 제공함에 본 발명의 목적이 있다.The present invention was devised to solve various problems of the conventional oil-based and water-based crack paints, and provides an aqueous crack paint that can be easily installed by anyone without environmental pollution or risk to human body during manufacture and construction. There is a purpose.
본 발명의 상기 목적은, 부분 알칼리화 폴리비닐 알코올 수지와 가교결합형 옵셋 잉크 에멀젼에 의해 달성된다.The above object of the present invention is achieved by a cross-linked offset ink emulsion with a partially alkaline polyvinyl alcohol resin.
본 발명의 수성 균열도료는, 부분 알칼리화 폴리비닐 알코올 수지 4.39∼21.31wt% 와, 수지 용해수 28.87∼62.19wt% 와, 가교결합형 옵셋 잉크 에멀젼 4.21∼15.29wt% 와, 소포제 0.08∼0.5wt% 와, 살균제 0.16∼0.66wt% 와, 수성 착색안료 0∼11.7wt% 와, 암모니아수와 같은 pH 조절제 0.08∼0.33wt% 및 희석수 19.25∼49.75wt% 로 조성되는 바, 각 성분의 역할과 함량 범위에 대한 한정 이유를 살펴 보면 다음과 같다.The aqueous crack coating of the present invention comprises 4.39 to 21.31 wt% of partially alkalized polyvinyl alcohol resin, 28.87 to 62.19 wt% of resin dissolved water, 4.21 to 15.29 wt% of crosslinking type offset ink emulsion, and 0.08 to 0.5 wt% of antifoaming agent. And 0.16 to 0.66 wt% of disinfectant, 0 to 11.7 wt% of aqueous coloring pigment, 0.08 to 0.33 wt% of pH adjuster such as ammonia water, and 19.25 to 49.75 wt% of dilution water. The reason for the limitation is as follows.
부분 알칼리화 폴리비닐 알코올 수지는, 비닐 알코올이 중합된 고분자 화합물이며 물 이외에는 녹지 않는 분말로서, 물에 용해된 상태에서 갖는 강한 접착력에 의해 본 발명 균열도료의 도막을 형성하며 수축력을 발생시키는 역할을 하게 되는 바, 그 함량이 4.39wt% 에 미치지 못하면 도막의 기본적인 접착력이 떨어질 뿐 아니라, 균열 형성 시간이 지나치게 길어지거나 적절한 형태의 균열을 형성시키지 못하게 되며, 그 함량이 21.31wt% 를 초과하게 되면 균열 형성 시간이 너무 빨라져 오히려 균열 상태가 외관상 바람직하지 못하게 되거나, 그 크기가 필요 이상으로 커지게 될 수 있다.Partially alkalized polyvinyl alcohol resin is a polymer compound polymerized with vinyl alcohol and insoluble except water, and forms a coating film of the crack coating of the present invention by a strong adhesive force in a state dissolved in water to generate shrinkage force. If the content is less than 4.39wt%, not only the basic adhesive strength of the coating film is deteriorated, but also the crack formation time becomes too long or does not form an appropriately shaped crack, and when the content exceeds 21.31wt%, the crack is formed. The time may become so fast that the crack state may become undesirable in appearance, or the size may become larger than necessary.
가교결합형 옵셋 잉크 에멀젼은, 상기 알코올 수지와 함께 도막 형성을 시키면서 균열의 크기를 조절하는 역할을 수행하는 동시에 도막에 내수성을 부여하는 역할을 수행하는 성분으로서, 그 함량이 4.21wt% 에 미치지 못하면 도막의 내수성이 떨어지게 되는 동시에 균열의 크기가 너무 작아져 특별한 경우를 제외하고는 바람직하지 않으며, 15.29wt% 를 초과하게 되면 내수성의 동반된 향상 효과는 없으면서 균열의 크기가 지나치게 커져 오히려 상대적으로 도막의 내수성이 떨어지게 될 뿐 아니라 외관적으로도 적절치 않을 수 있다.Cross-linked offset ink emulsion is a component that plays a role of controlling the size of the crack while forming a coating film together with the alcohol resin, and at the same time providing a water resistance to the coating film, if the content is less than 4.21wt% At the same time, the water resistance of the coating is reduced and the size of the crack is too small, which is not desirable except for a special case. When it exceeds 15.29wt%, the size of the crack is too large without the accompanying improvement effect of water resistance. In addition to poor water resistance, it may not be appropriate in appearance.
소포제와 살균제는, 액상 또는 겔상의 각종 조성물에 일반적으로 첨가되는 것으로, 그 함량이 각각 0.08wt% 및 0.16wt% 에 미치지 못하면 첨가 효과를 거의 얻을 수 없으나, 각각의 상한치인 0.5wt% 및 0.66wt% 를 초과하게 되어도 첨가 효과가 더 이상 향상되지는 않고 오히려 도료의 안정성을 저해할 수 있으며, 특히, 본 발명의 균열도료는 수용성이기 때문에 장시간 보관에 따른 도료의 부패와 열화를 방지하기 위하여 반드시 상기 살균제가 첨가되는 것이 바람직하다.Defoamers and fungicides are generally added to various liquid or gel compositions. If the content is less than 0.08 wt% and 0.16 wt%, respectively, the effect of addition is hardly obtained, but the upper limit of 0.5 wt% and 0.66 wt, respectively. Even if it exceeds%, the addition effect does not improve anymore, but rather it may hinder the stability of the paint. Particularly, since the crack paint of the present invention is water-soluble, it is necessary to prevent the deterioration and deterioration of the paint caused by long-term storage. It is preferred that fungicides are added.
수성 착색안료는, 도료에 색상을 부여하기 위한 것으로, 투명한 균열 상태를 얻기 위하여 첨가되지 않을 수도 있으며, 그 함량이 11.7wt% 를 초과하게 되면 수지 또는 잉크 에멀젼의 상대적인 비율 저하로 인하여 균열이 부족하거나 작아질 수가 있고, 부착력도 저하하게 된다.Aqueous coloring pigments are intended to impart color to the paint and may not be added to obtain a transparent crack. If the content exceeds 11.7 wt%, the cracks may be insufficient due to a lowered relative proportion of the resin or ink emulsion. It can become small, and adhesive force will also fall.
pH 조절제는, 도료의 pH를 8.0∼9.0 범위로 조절하여 도료가 안정화되도록 하기 위한 역할을 수행하는 성분으로서, 그 함량이 0.08wt% 에 미치지 못하면 pH 조절 효과가 거의 없으며, 0.33wt%를 초과하게 되면 pH 가 필요 이상 상승하게 되어 오히려 도료의 안정성을 해치게 된다.pH adjuster is a component that plays a role to stabilize the paint by adjusting the pH of the paint in the range of 8.0 to 9.0, if the content is less than 0.08wt%, there is almost no pH control effect, exceeding 0.33wt% If the pH rises more than necessary, the stability of the paint is impaired.
상기의 pH 조절제의 함량은 암모니아수를 기준으로 한 경우로서, 그 함량이 0.33wt%를 초과하게 되면 암모니아수 특유의 냄새가 심해져 시공시 불쾌감을 초래하게 되는 문제도 발생하게 된다.The content of the pH adjuster is based on ammonia water, and when the content exceeds 0.33wt%, a unique odor of ammonia water becomes severe, which causes problems of discomfort during construction.
그리고, 수지 용해수 및 희석수는 모두 동일한 물이나, 본 발명 도료의 제조 과정 중 서로 다른 단계에서 사용되기 때문에 구분한 것으로, 상기 용해수는 부분 알칼리화 폴리비닐 알코올 수지 4.39∼21.31wt% 를 용해하기 위하여 사용되는 물이며, 수지가 용해된 물에 기타의 다른 성분과 함께 물을 다시 혼합하여 최종적인 균열도료를 제조하게 되는바, 이때, 다른 성분들과 함께 추가되는 물을 희석수라 칭하였으며, 상기 용해수와 희석수, 특히, 용해수의 경우 도료의 안정성을 위하여 탈이온수(deionized water)를 사용하는 것이 바람직하다.In addition, the resin dissolved water and the dilution water are the same water, but are separated because they are used at different stages in the manufacturing process of the paint of the present invention, and the dissolved water dissolves 4.39 to 21.31 wt% of a partially alkaline polyvinyl alcohol resin. It is water used for the purpose, and water is mixed with other components in the water in which the resin is dissolved to prepare a final crack paint. In this case, water added together with other components was called dilution water. In the case of dissolved and dilute water, in particular, dissolved water, it is preferable to use deionized water for the stability of the paint.
상기와 같이 조성되는 본 발명 도료의 성분들 중 상기 부분 알칼리화 폴리비닐 알코올 수지는, 부분 알코올화 폴리에틸렌 수지, 전부 알코올화 폴리비닐 알코올 수지 등으로, 가교결합형 옵셋 잉크 에멀젼은 폴리비닐 아세테이트 에멀젼, 아크릴 라텍스, 스티렌 아크릴 라텍스 등으로 대체 할 수 있다.Among the components of the paint composition of the present invention as described above, the partially alkalized polyvinyl alcohol resin is a partially alcoholized polyethylene resin, an all alcoholized polyvinyl alcohol resin, or the like, and the crosslinkable offset ink emulsion is a polyvinyl acetate emulsion, an acrylic. It can be replaced with latex, styrene acrylic latex, etc.
그리고, 소포제는 광물유계통의 표면 활성제로, 살균제는 벤지소티아졸린(benzisothiazolin)으로, 암모니아수는 친환경 pH 조절제인 디엠에이이(DMAE, dimethylaminoethanol)로도 대체 할 수도 있으며, 각 대체 성분의 중량 백분율은 대체되기 전의 각 해당 성분들과 동일한 효과를 얻을 수 있도록 상기의 함량 범위가 조절될 수 있다.In addition, antifoaming agent may be replaced with mineral oil-based surface active agent, disinfectant may be benzisothiazolin, and ammonia water may be replaced with dimethylaminoethanol (DMAE), an environmentally friendly pH control agent. The above content range can be adjusted to obtain the same effect as each of the corresponding ingredients before the preparation.
