본 발명은 습식벽체 및 건식벽체 방수면에 흡수율이 1%이하인 타일 적용을 위한 폴리머계 고성능 타일접착제로서 종래의 제품들과는 달리 VA-VV-E(vinyl acetate, vinyl versatate, ethylene)삼원공중합체 재유화형 분말수지와 HEMC(Hydroxy Ethyl Methyl Cellulose)를 사용함으로서 탄성 및 내수성, 내구성, 접착강도를 향상 시켜 주상복합건물, 상가건물, 오피스 등 고층건물의 습식벽체 및 건식벽체 방수면에 흡수율이1%이하인 타일을 부착 가능하게 하여 타일 들뜸 및 탈락현상을 방지 할 수 있는 기능성 타일접착제이다.The present invention is a polymer-based high-performance tile adhesive for tile application having a water absorption rate of 1% or less on wet and dry wall waterproof surfaces. Unlike conventional products, VA-VV-E (vinyl acetate, vinyl versatate, ethylene) terpolymer reemulsification type By using powder resin and HEMC (Hydroxy Ethyl Methyl Cellulose), it improves elasticity, water resistance, durability, and adhesive strength, so that the water absorption rate is less than 1% on the wet wall and dry wall waterproof surface of high-rise building such as columnar composite building, mall building, and office It is a functional tile adhesive that can be attached to prevent the lifting and falling of tiles.

초기에는 시멘트, 규사에 메틸셀룰로우즈를 첨가하여 보수성과 점성을 높여 접착용 도자기질 타일시멘트가 주로 사용되다가 타일의 크기가 커지고, 보다 높은 성능을 요구하면서 EVA계 재유화형 분말수지와 PVA를 첨가하여 접착력을 강화한 특1993 -0009347, PVA를 소량 첨가하고 플라이애쉬를 시멘트 대체재로 첨가하여 내구 성을 향상시킨 특2002-0009336와 같이 일반 접착용 도자기질 타일시멘트에 분말형 접착강화제를 첨가하여 접착력을 강화시킨 제품들이 사용되게 되었다.Initially, methyl cellulose is added to cement and silica sand to improve water retention and viscosity, and adhesive ceramic tile cement is mainly used, but the size of tiles is increased, and EVA reemulsifying powder resin and PVA are added while demanding higher performance. As a special 193 -0009347 enhanced adhesion, a small amount of PVA and fly ash added as a cement substitute to improve the durability, such as special 2002-0009336 added a powder-type adhesive reinforcement to the porcelain tile cement for general adhesion Fortified products have been used.

그리고 타일의 크기가 점점 더 대형화 되어가면서 타일 접착제도 고급화가 진행되어 재유화형 분말수지와 증점제 첨가량이 늘어나 부착강도를 높이고 큰 타일이 자중에 의해 미끄러지지 않도록 증점제의 양이 늘어난 특2003-0015566와 같은 형태의 접착제와 온도변화에 따른 온돌구조 시스템 및 내부에서 폴리싱 타일의 들뜸 및 탈락을 방지하기 위하여 내구성이 우수한 아크릴계 재분산 분말수지 및 소석회를 첨가하여 만든 등록번호 10-0937635와 같은 제품들이 사용되고 있다.In addition, as the size of tiles increases, tile adhesives are also advanced, increasing the re-emulsifying powder resin and the amount of thickener added, thereby increasing the adhesive strength and increasing the amount of thickener to prevent large tiles from slipping by their own weight. Products such as registration number 10-0937635 made by adding durable acrylic redispersible powdered resin and calcined lime are used to prevent the lifting and dropping of the polished tile in the ondol structure system and the inside due to the temperature change and the adhesive.

최근 들어 주상복합건물, 백화점, 상가건물, 오피스 등 구조물이 고층화됨에 따라 구조물의 자중을 감소시키기 위하여 건식벽체가 적용되고 있고, 욕실인 경우에는 건식벽체에 타르우레탄 방수재 또는 일액형 탄성도막방수재로 방수를 하고, 방수면 위에 일반 타일에 비해 내구성 및 미관이 우수한 흡수율이1%이하인 타일이 시공되고 있다.Recently, as the structure of commercial buildings, department stores, malls, offices, etc. has become higher, drywall is being applied to reduce the weight of the structure.In the case of bathrooms, drywall is waterproofed with tar urethane waterproofing material or one-component elastic film waterproofing material. On the waterproof surface, a tile having a water absorption rate of 1% or less, which is excellent in durability and aesthetics, is constructed on the waterproof surface.

그러나 특2003-0015566(고성능타일시멘트)와 같은 형태의 제품, 등록번호 10-0937635(폴리싱타일시멘트계접착제)와 같은 형태의 제품은 고층건물 건식벽체의 방수면에 흡수율이1%이하인 타일을 시공 할 경우 타일의 들뜸 및 탈락현상이 발생하여 문제가 되고 있다. 이러한 주된 원인은 건식벽체의 수축,팽창,변형 및 건식벽체 방수면에서의 부착성능을 충분히 발휘하지 못하여 타일의 들뜸 및 탈락현상이 발생하게 된다.However, products in the form of special 2003-0015566 (high performance tile cement), and in the form of registration number 10-0937635 (polishing tile cement adhesive), can be used to install tiles with water absorption of 1% or less on the drywall of high-rise buildings. In this case, the lifting and dropping of the tile is a problem. These main causes are the contraction, expansion, deformation of the drywall and insufficient adhesion performance on the drywall waterproof surface, causing the tiles to be lifted and dropped.

따라서, 타일 접착 시장에서는 고층건물 건식벽체의 방수면에 흡수율이1%이 하인 타일을 시공 할 경우 타일의 들뜸 및 탈락현상을 방지 할 수 있는 우수한 접착제의 개발이 매우 필요로 하고 있다.Therefore, in the tile adhesive market, when a tile having a water absorption rate of 1% is applied to the waterproof surface of a high-rise building drywall, there is a great need to develop an excellent adhesive that can prevent the lifting and dropping of tiles.

본 발명은 상기한 종래 기술에서의 문제점을 개선하기 위해 제안된 것으로서, 고층건물 건식벽체의 방수면에서 흡수율이1%이하인 타일의 들뜸 및 탈락 현상을 방지하기 위하여 탄성, 내수성, 내구성 및 방수면에서 접착강도가 우수한 VA-VV-E(vinyl acetate, vinyl versatate, ethylene)삼원공중합체 재유화형 분말수지 및 HEMC(Hydroxy Ethyl Methyl Cellulose)를 사용하여 고층건물 건식벽체의 방수면에서 흡수율이1%이하인 타일 시공 시 접착강도와 탄성 및 변형율을 향상 시켜 타일의 들뜸 및 탈락을 방지 할 수 있는 습식벽체 및 건식벽체 방수면에 흡수율이 1%이하인 타일 적용을 위한 폴리머계 고성능 타일접착제를 제공하는데 그 목적이 있다.The present invention has been proposed to improve the above problems in the prior art, in order to prevent the lifting and falling of the tiles having a water absorption of 1% or less in the waterproof surface of the high-rise building dry wall in terms of elasticity, water resistance, durability and waterproof Tiles with absorbance less than 1% in the waterproof surface of high-rise drywall using VA-VV-E (vinyl acetate, vinyl versatate, ethylene) terpolymer re-emulsified powder resin and HEMC (Hydroxy Ethyl Methyl Cellulose) Its purpose is to provide polymer-based high-performance tile adhesives for tile applications with absorption of less than 1% on wet and dry wall waterproof surfaces that can prevent lifting and dropping of tiles by improving adhesive strength, elasticity and strain during construction. .

일반적으로 사용되는 VAE(Vinyl Acetate Ethylen)재유화형 분말수지와 아크릴계 재유화형 분말수지는 방수면에서 흡수율이1%이하인 타일 시공 시 접착강도와 탄성 및 변형율이 충분히 발휘되지 못하여 타일의 들뜸 및 탈락 현상이 발생하여 본 발명에서는 상기한 바와 같이 방수면에서의 접착강도가 우수한 VA-VV-E(vinyl acetate, vinyl versatate, ethylene)삼원공중합체 재유화형 분말수지 및 HEMC(Hydroxy Ethyl Methyl Cellulose)를 사용하여 고층건물 건식벽체의 방수면에서 흡수율이1%이하인 타일 시공시 들뜸 및 탈락 현상을 방지 할 수 있는 습식벽체 및 건식벽체 방수면에 흡수율이 1%이하인 타일 적용을 위한 폴리머계 고성능 타일접착제를 제시하고자 하였다.VAE (Vinyl Acetate Ethylen) re-emulsified powder resin and acryl-based re-emulsified powder resin which are generally used are not sufficiently exhibited the adhesive strength, elasticity and strain when water absorption is less than 1%. In the present invention, as described above, a high-layer using VA-VV-E (vinyl acetate, vinyl versatate, ethylene) terpolymer reemulsified powder resin and HEMC (Hydroxy Ethyl Methyl Cellulose) having excellent adhesive strength on the waterproof surface We tried to present a polymer-based high-performance tile adhesive for the application of tiles with water absorption of 1% or less on the wet and dry wall waterproof surfaces, which can prevent lifting and dropping, when constructing tiles with water absorption of 1% or less on the waterproof surface of building drywall. .

본 발명품은 고층건물 건식벽체의 방수면에서 흡수율이1%이하인 타일 시공시 방수면에서의 접착강도가 우수하고 탄성 및 변형율이 뛰어나 타일의 들뜸 및 탈락현상을 방지 하여 건식벽체 내장 마감용 타일 시공 품질을 확보하는데 효과가 있다.The present invention has excellent adhesive strength on waterproof surface and excellent elasticity and strain when installing tiles with water absorption of 1% or less on the waterproof surface of high-rise drywall, preventing the lifting and dropping of tiles, thereby improving the quality of tile construction for drywall interior finishing. It is effective to secure.

상기의 목적을 달성하기 위하여, 본 발명의 타일 접착제는 전체 조성물에 대하여 35∼45중량%의 백색 포틀랜드 시멘트, 25∼40중량%의 60∼100 mesh 규사, 15∼30중량%의 100∼200 mesh 규사, 0.3∼1.5중량%의 HEMC(Hydroxy Ethyl Methyl Cellulose), 1∼5중량%의 셀룰로우즈 화이바, 2∼10중량%의 VA-VV-E(vinyl acetate, vinyl versatate, ethylene)삼원공중합체 재유화형 분말수지를 포함하는 것을 특징으로 한다.In order to achieve the above object, the tile adhesive of the present invention is 35 to 45% by weight of white portland cement, 25 to 40% by weight of 60 to 100 mesh silica sand, 15 to 30% by weight of 100 to 200 mesh Silica sand, 0.3-1.5% by weight of Hydroxy Ethyl Methyl Cellulose (HEMC), 1-5% by weight of cellulose fiber, 2-10% by weight of VA-VV-E (vinyl acetate, vinyl versatate, ethylene) terpolymer It characterized in that it comprises a re-emulsified powder resin.

백색 포틀랜트 시멘트는 KS L 5204 에 적합한 것을 사용하면 된다. 다만 35중량% 미만이 첨가되면 강도가 떨어지고, 45중량% 이상이 첨가되면 가사시간이 짧아진다.As the white portland cement, one suitable for KS L 5204 may be used. However, when less than 35% by weight is added, the strength drops, and when more than 45% by weight is added, the pot life is shortened.

규사는 천연사를 분쇄하여 얻은 것으로 시멘트의 양생에 영향을 줄 수 있는 이물질을 포함하지 않는 것을 사용해야 하며, 60∼100 mesh 규사는 25∼40중량%, 100∼200 mesh 규사는 15∼30중량%를 적용하도록 한다. 타일접착제는 규사의 입도에 따라 타일의 미끄러짐이 발생할 수 있고, 강도의 저하가 있으므로 입도를 지키는 것이 중요하다.Silica sand is obtained by pulverizing natural sand and should not contain foreign substances that can affect the curing of cement. 25 to 40% by weight of 60-100 mesh silica and 15 to 30% by weight of 100-200 mesh silica To apply. The tile adhesive may cause slippage of the tile depending on the size of the silica sand, and there is a decrease in strength, so it is important to keep the particle size.

HEMC(Hydroxy Ethyl Methyl Cellulose)는 시멘트 제품에 첨가되어 점착력과 보수력을 나타내는 것으로 0.3중량%보다 적으면 점도의 저하로 타일 미끄러짐 및 보수율 저하가 발생하며, 1.5중량%를 넘으면 점도가 너무 올라가 작업성이 떨어져 타일 접착제로서 적합하지 않게 된다. 따라서 HEMC(Hydroxy Ethyl Methyl Cellulose)는 0.3∼1.5중량%가 첨가되어야 한다. HEMC(Hydroxy Ethyl Methyl Cellulose)는 바람직하게는 2% 수용액의 점도가 30,000∼40,000 mPa.s 이고 입자크기가 250㎛체 통과율이 90.0% 이상인 것을 특징으로 한다.HEMC (Hydroxy Ethyl Methyl Cellulose) is added to cement products to show adhesiveness and water retention.As it is less than 0.3% by weight, tile slippage and repair rate decrease due to viscosity decrease, and when it exceeds 1.5% by weight, viscosity increases too much and workability It is not suitable as a tile adhesive. Therefore, HEMC (Hydroxy Ethyl Methyl Cellulose) should be added 0.3 to 1.5% by weight. Hydroxy Ethyl Methyl Cellulose (HEMC) is preferably characterized in that the viscosity of the 2% aqueous solution is 30,000 to 40,000 mPa · s and the particle size of the 250 μm sieve is 90.0% or more.

HPMC(Hydroxy Propyl Methyl Cellulose)와 MEHEC(Methyl Ethyl Hyedroxypropyl Ethyl Cellulose)는 방수면에서 흡착력과 접착강도가 떨어져 반드시 방수면에서 흡착력과 접착강도가 우수한 HEMC (Hydroxy Ethyl Methyl Cellulose)를 사용해야 한다.Hydroxy Propyl Methyl Cellulose (HPMC) and Methyl Ethyl Hyedroxypropyl Ethyl Cellulose (MEHEC) must use HEMC (Hydroxy Ethyl Methyl Cellulose), which has excellent adsorption and adhesive strength on the water-proof side.

셀룰로오즈 화이바는 본 발명에 첨가되어 크랙방지 및 타일 미끄러짐 저항성을 향상시키는 역할을 한다. 1중량%보다 적으면 크랙 또는 타일 미끄러짐이 발생할 수 있고, 5중량%보다 많으면 혼합 후 제품상태가 거칠어지고 점도상승이 빨라 가사시간이 줄어든다. 따라서, 1∼5중량%의 혼입율이 적당하다.Cellulose fibers are added to the present invention to serve to improve crack resistance and tile slip resistance. If less than 1% by weight, cracks or tile slip may occur. If more than 5% by weight, the product becomes rough after mixing and the viscosity rises rapidly, thereby reducing the pot life. Therefore, the mixing ratio of 1 to 5% by weight is appropriate.

재유화형 분말수지는 시멘트와 함께 접착강도와 굴곡강도, 탄성을 갖도록 해주는 물질로 2∼10중량%를 첨가하여야 한다. 2중량% 보다 적으면 충분한 접착강 도와 굴곡강도 등을 얻을 수 없고, 10중량% 보다 많으면 미끄럼 저항성 및 내수 부착강도가 떨어진다.Reemulsifying powder resin should be added with cement in an amount of 2 to 10% by weight to provide adhesive strength, flexural strength and elasticity. If it is less than 2% by weight, sufficient adhesive strength and flexural strength cannot be obtained. If it is more than 10% by weight, the slip resistance and the water resistance to adhesion are inferior.

일반적으로 사용되는 VAE(Vinyl Acetate Ethylen)재유화형 분말수지와 아크릴계 재유화형 분말수지는 방수면에서 접착강도 및 변형율이 떨어져 반드시 VA-VV-E(vinyl acetate, vinyl versatate, ethylene)삼원공중합체 재유화형 분말수지를 사용해야 한다.VAE (Vinyl Acetate Ethylen) re-emulsified powder resin and acryl-based re-emulsified powder resin are generally VA-VV-E (vinyl acetate, vinyl versatate, ethylene) terpolymer reemulsification type because they have low adhesive strength and strain in waterproof Powder resin should be used.

VA-VV-E(vinyl acetate, vinyl versatate, ethylene)삼원공중합체 재유화형 분말수지는 vinyl acetate, vinyl versatate, ethylene를 공중합 시켜 만든 액상 에멀젼을 스프레이로 분무 건조 시켜 분말화 시킨 제품이다.VA-VV-E (vinyl acetate, vinyl versatate, ethylene) terpolymer reemulsified powder resin is a product made by spray-drying a liquid emulsion made by copolymerizing vinyl acetate, vinyl versatate, and ethylene by spray drying.
