Description
본 발명은 벽체와 벽지 간의 접착성을 향상시키는 액상 접착 증진재에 관한 것으로서, 더욱 상세하게는 물과 에틸 아크릴레이트 및 부틸 아크릴레이트를 주성분으로 하며 스프레이 용기를 이용하여 분무가 가능한 인체에 무해한 액상 접착 증진재를 제공함으로써 벽체와 벽지 간의 접착성을 향상시킴은 물론, 액상의 접착 증진재와 전분풀을 혼합하여 사용할 경우 접착이 잘 되지 않는 난접착 물질에 접착력을 향상시킬 수 있는 액상 접착 증진재에 관한 것이다.The present invention relates to a liquid adhesion promoting material for improving the adhesion between the wall and the wallpaper, and more particularly, liquid adhesion that is harmless to the human body that can be sprayed using a spray container based on water and ethyl acrylate and butyl acrylate Providing an enhancer to improve the adhesion between the wall and the wallpaper, as well as a liquid adhesion enhancer that can improve the adhesion to the poor adhesion material that is difficult to adhere when used in combination with the liquid adhesion promoter and starch paste It is about.
일반적으로 주거를 목적으로 하는 주택 건물이나 사무실, 음식점 등의 벽체 표면에는 미관을 목적으로 벽지를 부착하게 되며, 이러한 벽지를 부착하기 위해서는 접착제로서 주로 전분을 주성분으로 하는 풀을 사용하게 된다.In general, wallpaper is attached to the surface of a wall of a house building, office, restaurant, etc. for the purpose of aesthetic purposes, and to attach such wallpaper, a paste mainly containing starch is used as an adhesive.
본 발명에서 사용되는 용어 중에서 벽체라 함은 콘크리트, 목재, MDF, 가죽, 고무, 합성수지 패널, 유리, 금속면 등을 모두 포함하는 것으로서 설명의 편의상 '벽체'라 총칭한다.The term wall used in the present invention includes concrete, wood, MDF, leather, rubber, synthetic resin panels, glass, metal surfaces, etc., and is collectively referred to as 'wall' for convenience of description.
상기와 같이 풀을 사용하여 벽체에 벽지를 부착하기 위해서는 통상적으로 두 가지의 시공방법으로 이루어진다.As described above, in order to attach the wallpaper to the wall using the grass, there are usually two construction methods.
첫째는 벽지를 적정한 길이로 절단한 후, 벽지 이면에 풀을 도포하여 즉시 벽체에 부착하는 방법이며, 둘째는 도배 전문가에 의해 주로 이루어지는 방법으로서 아파트와 같이 규격화된 실내의 경우 다른 장소에서 많은 량의 벽지를 적정한 길이로 절단하고, 그 절단된 벽지 이면에 풀을 도포한 후, 도배 장소로 이동하여 풀이 도포된 벽지를 벽체에 부착하는 방법이다.The first method is to cut the wallpaper into proper lengths, and then paste the grass on the back of the wallpaper and immediately attach it to the wall. The second method is mainly done by the expert. After the wallpaper is cut to an appropriate length, the grass is applied to the back surface of the cut wallpaper, the wallpaper is moved to a place where the grass is applied and the wallpaper is applied to the wall.
상기와 같이 첫째 시공방법의 경우 벽지를 부착하기 전에 벽체에 액상 접착 증진재를 분무하여 벽지를 벽체에 부착함에 따라 접착력을 향상 시킬 수 있으며, 둘째 시공방법의 경우 많은 량의 벽지에 풀을 먼저 도포함으로써 벽지 마다 풀의 도포 시점에 차이가 있을 뿐만 아니라, 특히 도배장소로 이동하는 동안에 풀이 건조되는 상태가 발생되어 벽체와 벽지 간에 접착력이 저하되는 현상이 발생하게 되어 풀을 재차 도포하는 등 시공상 많은 문제점이 있으며, 특히 벽체가 평탄하지 못할 경우 벽체와 벽지 간의 접착력은 거의 발생하지 않는 문제점이 있는 것이다. 또는 신규 주택이 아닌 리모델링, 벽지의 교체 등 기존의 벽지 위에 시공을 하는데, 이때 난접착 코팅처리 된 벽체에 시공하면 접착력이 약해질 수 있는 문제점이 있다. As described above, in the case of the first construction method, the adhesive strength can be improved by spraying the liquid adhesion promoter on the wall before attaching the wallpaper to the wall, and in the second construction method, the grass is first applied to a large amount of wallpaper. As a result, there is a difference in the time of application of the grass for each wallpaper, and in particular, the state of drying the grass occurs while moving to the place of distribution, and the adhesive force decreases between the wall and the wallpaper. There is a problem, especially when the wall is not flat, there is a problem that the adhesion between the wall and the wallpaper hardly occurs. Or construct a new wallpaper over the existing wallpaper, such as remodeling, replacement of the wallpaper, at this time there is a problem that the adhesive strength may be weakened when installed on a wall that is difficult adhesive coating treatment.
상기와 같은 문제점을 해소하기 위해 종래에는 벽체와 벽지 간에 접착력을 높이기 위해 접착 증진재 종류가 개발되었으나, 거의 대부분이 점성이 높은 고점도의 제품으로서 전용 주걱(헤라)을 사용하여 도포하는 한편, 벽체의 굴곡부분에는 고점도 접착 증진재로 채워 평탄화 하여야 하며, 특히 높은 부분의 벽체 또는 천정의 경우 사다리를 이용하여야 하므로 시공성 저하의 문제점을 안고 있을 뿐만 아니라, 고가로 인해 사용을 기피하고 있는 실정이다.In order to solve the above problems, conventionally, a type of adhesion promoting material has been developed to increase adhesion between the wall and the wallpaper, but almost all of them are coated with a high-viscosity high viscosity product using a spatula. The curved part should be flattened with a high viscosity adhesive enhancer, and especially in the case of a wall or a ceiling of a high part, a ladder should be used, and thus the construction is not in use due to the high cost.
그 외에도 대한민국 공개특허 제2000-0060479호(공개일자:2000년10월16일)에서는 천연 원적외선 광물질인 일라이트를 벽지 접착용 풀에 소정량 혼합함으로써 접착 후 가옥의 실내를 탈취 및 정균하여 각종 환경오염을 예방할 수 있도록 제안되었으며, 또한 대한민국 특허 제549367호(등록일자:2006년01월27일)에서는 전분계 풀의 제조 시 지속적인 항균성을 유지할 수 있도록 제안되었으며, 또한 대한민국 공개특허 제2010-0022843호(공개일자:2010년03월03일)에서는 전분질 도배 풀에 백운모와 같은 광물 분말과 은 나노 용액이 첨가되어 광물질이 갖는 강한 흡착력, 음이온 치환능력 및 다량의 음이온과 원적외선 방출효과 등에 의하여 기능성이면서도 장기간 유통하더라도 변질되지 않고 콘크리트의 독성을 중화시켜 쾌적한 거주환경을 조성할 수 있도록 제안되었다.In addition, the Republic of Korea Patent Publication No. 2000-0060479 (published date: October 16, 2000) by mixing a predetermined amount of natural far-infrared mineral illite in the wallpaper paste paste deodorizing and bactericidal interior of the house after bonding to various environments It has been proposed to prevent contamination, and Korean Patent No. 55367 (Registration Date: January 27, 2006) has been proposed to maintain continuous antimicrobial activity during the production of starch-based paste, and also Korean Patent Publication No. 2010-0022843 On March 3, 2010, mineral powders such as mica and silver nano solution were added to starch paper pools to provide functional and long-term results due to the strong adsorption power, anion substitution capacity, and large amount of anion and far-infrared radiation effects of minerals. It is proposed to create a pleasant living environment by neutralizing the toxicity of concrete without altering the distribution.
상기와 같은 종래 기술는 전분 풀에 탈취 및 정균, 항균, 음이온과 원적외선 방출효과와 같은 기능성에 초점이 맞추어져 있으나, 벽지에 도포된 풀과 벽체와의 접착성을 향상시킬 수 없는 것이다.The prior art as described above focuses on functionality such as deodorization and bacteriostatic, antimicrobial, anion and far-infrared emission effects in starch grass, but it is not possible to improve the adhesion between the grass and the wall applied to the wallpaper.

상기 계면활성제는 음이온형, 비이온형을 같이 사용하며 물에 모노머를 분산시켜 균일하게 혼합하는 일반적으로 알려진 통상의 물질을 사용한 것으로서, 전체 100 중량부에 대하여 1.5 중량부 미만으로 첨가할 경우 용매인 물과 모노머 간의 친수성과 친유성이 저하되어 혼합 및 균질화가 어려우며, 전체 100 중량부에 대하여 6 중량부 이상 첨가될 경우 용매인 물과 모노머 간의 친수성과 친유성의 효과를 더 이상 기대할 수 없어 1.5~5 중량부 범위내에서 첨가하는 것이 바람직하다.The surfactant is an anionic or nonionic type, and is generally used as a conventional substance which is uniformly mixed by dispersing monomers in water. When the surfactant is added in an amount of less than 1.5 parts by weight based on 100 parts by weight, the solvent is a solvent. The hydrophilicity and lipophilic property between water and monomer are reduced, making it difficult to mix and homogenize. When more than 6 parts by weight is added to 100 parts by weight, the effect of hydrophilicity and lipophilic property between solvent and water can no longer be expected. It is preferable to add in 5 weight part range.

상기 완충제는 전체 물성과 점도에 영향을 끼치지 않는 전체 100 중량부에 대하여 0.3~1 중량부 범위내에서 첨가하는 것이 바람직하다.The buffer is preferably added in the range of 0.3 to 1 parts by weight based on 100 parts by weight of the total physical weight and viscosity.
상기 반응단계가 완료되면 반응기의 온도를 72℃로 유지한 상태에서 약 90분 동안 숙성시키는 숙성단계를 수행한 다음, 상온에서 냉각하는 냉각단계를 수행함으로써 본 발명에 따른 벽체와 벽지 간의 접착성을 향상시키는 액상 접착 증진재의 제조과정을 완료하게 된다.When the reaction step is completed after performing the aging step of aging for about 90 minutes while maintaining the temperature of the reactor at 72 ℃, and then performing a cooling step of cooling at room temperature adhesion between the wall and the wallpaper according to the present invention Complete the manufacturing process of the liquid adhesion promoter to improve.
상기와 같이 이루어진 본 발명에 따른 벽체와 벽지 간의 접착성을 향상시키는 액상 접착 증진재의 용매로 사용되는 물이 52~64중량부가 포함되어 있어 농도가 낮아 스프레이 방식으로 벽체에 도포가 가능하게 된다. 52 to 64 parts by weight of water used as a solvent of the liquid adhesion promoting material to improve the adhesion between the wall and the wallpaper according to the present invention made as described above is possible to apply to the wall in a low spray method.
상기와 같이 이루어진 본 발명에 따른 벽체와 벽지 간의 접착성을 향상시키는 액상 접착 증진재를 사용하여 벽체에 벽지를 부착하는 과정을 설명하면 다음과 같다.Referring to the process of attaching the wallpaper to the wall using a liquid adhesion promoter to improve the adhesion between the wall and the wallpaper according to the present invention made as described above are as follows.
먼저, 전술한 바와 같이 물, 에틸 아크릴레이트, 부틸 아크릴레이트, 스티렌, 아크릴산, 메타 아크릴산, 과황산암모늄, 계면활성제, 완충제를 포함하는 인체에 무해한 액상 접착 증진재를 스프레이에 충진한 후, 벽체에 분사 도포한다.First, as described above, the spray-filled liquid adhesion promoter which is harmless to the human body, including water, ethyl acrylate, butyl acrylate, styrene, acrylic acid, methacrylic acid, ammonium persulfate, a surfactant, and a buffer, Spray application.
상기의 액상 접착 증진재는 벽체에 도포된 후, 일정한 시간이 경과되면 상온에서 용매인 물이 건조되어 모노머의 에틸 아크릴레이트, 부틸 아크릴레이트, 스티렌, 아크릴산, 메타 아크릴산의 혼합물에 의해 벽체에 견고하게 밀착 결합되어 접착되는 한편, 표면에는 끈적임의 접착력이 형성되며, 3~7일이 경과하여도 접착력은 그 상태로 유지될 뿐만 아니라, 벽체에 굴곡면이 형성되어 있을 경우에도 별도의 평탄화 작업이 필요하지 않게 된다.The liquid adhesion promoter is applied to the wall, and after a certain time has elapsed, the solvent water is dried at room temperature and firmly adhered to the wall by a mixture of ethyl acrylate, butyl acrylate, styrene, acrylic acid, and methacrylic acid of the monomer. While bonded and adhered, a sticky adhesive force is formed on the surface, and even after 3 to 7 days, the adhesive force is maintained as it is, and even if a curved surface is formed on the wall, no additional flattening is required. Will not.
이 후, 전술한 바와 같이 아파트와 같이 규격화된 실내의 경우 다른 장소에서 많은 량의 벽지를 적정한 길이로 절단하고, 그 절단된 벽지 이면에 풀을 도포한 후, 도배 장소로 이동한다.Thereafter, in the case of a standardized room such as an apartment, as described above, a large amount of wallpaper is cut to an appropriate length in another place, the grass is applied to the back of the cut wallpaper, and then moved to the place of delivery.
그 다음, 본 발명의 액상 접착 증진재가 도포된 벽체에 풀이 도포된 벽지를 부착하게 되면 모노머의 에틸 아크릴레이트, 부틸 아크릴레이트, 스티렌, 아크릴산, 메타 아크릴산의 혼합물에 의한 접착력이 발생되어 전분 풀이 도포된 벽지 이면과의 매개체 역할을 하게 되어 결합력이 향상됨으로써 벽체와 벽지 간에 견고하게 부착되는 것이다.Then, when the grass-coated wallpaper is attached to the wall to which the liquid adhesion promoter of the present invention is applied, adhesive force is generated by a mixture of ethyl acrylate, butyl acrylate, styrene, acrylic acid, and methacrylic acid of the monomer to which starch paste is applied. It acts as a medium to the back of the wallpaper, thereby improving the bonding force, so that it is firmly attached between the wall and the wallpaper.
이와 같이 본 발명에 따른 액상 접착 증진재가 벽체에 도포된 상태에서 이면에 전분 풀이 도포된 벽지를 부착하게 되면 상기 액상 접착 증진재와 전분풀이 서로 결합됨으로써 벽지가 벽체에 용이하게 부착되는 것이다.As described above, when the liquid adhesion promoting material according to the present invention is applied to the wall and the wallpaper with the starch paste applied to the wallpaper is attached, the liquid adhesion promoting material and the starch paste are easily bonded to the wall.
따라서 벽지 이면에 도포된 전분풀이 시간이 경과함에 따라 수분이 증발되는 건조 현상이 발생될 경우에도 액상 접착 증진재에 의해 접착력이 향상됨으로써 도배가 쉽게 이루어지게 될 뿐만 아니라, 간단한 스프레이 작업으로 벽체에 도포가 가능하고, 벽체가 평탄하지 못할 경우에도 별도의 평탄화 작업이 필요하지 않으며, 스프레이 작업으로 벽체에 도포한 후에도 3~7일이 경과하여도 접착력은 그대로 유지되어 시공성이 높을 뿐만 아니라, 벽체의 종류 즉 콘크리트, 목재, MDF, 가죽, 고무, 합성수지 패널, 유리, 금속면에도 동일한 효과를 얻을 수 있는 것이다.Therefore, even when the starch paste applied to the back surface of the wallpaper is dried, the evaporation of moisture occurs as time elapses, the adhesion is enhanced by the liquid adhesion promoter, and the papering is easily performed. Even if the wall is not flat, no additional flattening is required, and even after 3 to 7 days even after applying to the wall by spraying, the adhesive force is maintained as it is, and the workability is high. In other words, the same effect can be obtained in concrete, wood, MDF, leather, rubber, plastic panels, glass, and metal surfaces.
본 발명의 다른 실시예로서 상기의 액상 접착 증진재를 전분풀과 일정 비율로 혼합하여 사용할 경우에도 동일하게 벽체와 벽지 간의 접착력 향상을 기대할 수 있다.As another embodiment of the present invention can be expected to improve the adhesion between the wall and the wallpaper in the same way even when the liquid adhesion promoter is mixed with the starch pool in a certain ratio.
즉, 물 52~64 중량부와, 에틸 아크릴레이트 10~15 중량부와, 부틸 아크릴레이트 15~23 중량부와, 스티렌 2~4 중량부와, 아크릴산 1~3 중량부와, 메타 아크릴산 1~3 중량부와, 계면활성제 1.5~5 중량부와, 첨가제 0.3~1 중량부와, 과황산암모늄 0.5~1.5 중량부와, 완충제 0.3~1 중량부로 이루어진 액상 접착 증진재를 전분풀 100 중량부에 대하여 5~20 중량부를 첨가 및 혼합하여 사용한다.That is, 52 to 64 parts by weight of water, 10 to 15 parts by weight of ethyl acrylate, 15 to 23 parts by weight of butyl acrylate, 2 to 4 parts by weight of styrene, 1 to 3 parts by weight of acrylic acid, and 1 to methacrylic acid. 100 parts by weight of a liquid adhesion promoter comprising 3 parts by weight, 1.5 to 5 parts by weight of surfactant, 0.3 to 1 part by weight of additives, 0.5 to 1.5 parts by weight of ammonium persulfate, and 0.3 to 1 parts by weight of buffer. It is used by adding and mixing 5 to 20 parts by weight.
상기와 같이 전분풀에 액상 접착 증진재를 혼합한 상태에서 벽지에 도포한 후, 장시간이 경과하여 수분이 증발할 경우에도 벽체와의 접착력은 그대로 유지됨으로써 동일한 효과를 얻게 되는 것이다.After the coating on the wallpaper in the state of mixing the liquid adhesion promoter in the starch pool as described above, even if the water evaporates after a long time, the adhesive strength with the wall is maintained as it is to obtain the same effect.
여기서 상기 액상 접착 증진재를 전분풀 100 중량부에 대하여 5 중량부 미만으로 첨가할 경우 접착 증진재의 기능을 할 수 없으며, 액상 접착 증진재를 전분풀 100 중량부에 대하여 21 중량부 이상으로 첨가할 경우 원가 상승의 요인이 되므로 5~20 중량부 범위 내에서 첨가하는 것이 바람직하다.In this case, when the liquid adhesion promoter is added in an amount less than 5 parts by weight based on 100 parts by weight of starch paste, the adhesion promoter may not function, and the liquid adhesion promoter may be added in an amount of 21 parts by weight or more based on 100 parts by weight of starch paste. In this case, it is preferable to add within the range of 5 to 20 parts by weight since it will be a factor of cost increase.
