Description
본 발명은 불연성 분말형 마감재 조성물에 관한 것으로, 더욱 상세하게는 분말 상태의 백색 마이크로 시멘트 10~15중량%, 분말 상태의 백색 석고 10~20중량%, 재유화형 분말수지 2~6중량%, 증점제 1~2중량%, 분산제 1~2중량%, 응결조절제 1~2중량% 및 증량제로서 규사 40~60중량%의 조성물을 포함하되, 불연성, 내열성, 내화성, 내마모성, 방음성, 방수성 및 내구성이 우수하며 물과 혼합 시 수화반응에 의해 발현되는 접착강도와 건축물의 일면에 도포될 때 작업성이 우수한 것을 특징으로 하는 불연성 분말형 마감재 조성물에 대한 것이다. The present invention relates to a non-flammable powder type finishing material composition, and more particularly, 10 to 15% by weight of white microcement in powder form, 10 to 20% by weight of white gypsum in powder form, 2 to 6% by weight of redispersible powder resin, thickener 1 to 2% by weight, 1 to 2% by weight of a dispersant, 1 to 2% by weight of a setting control agent, and 40 to 60% by weight of silica sand as an extender, but having excellent nonflammability, heat resistance, fire resistance, abrasion resistance, sound insulation, waterproofness and durability It relates to a non-flammable powder-type finishing material composition characterized by excellent adhesive strength expressed by hydration reaction when mixed with water and excellent workability when applied to one side of a building.
건축물에서는 외부의 기후 조건에 영향을 받지 않고, 가능한 실내의 온도를 일정하게 유지하면서 외관을 꾸미기 위해 페인트를 칠하게 된다. 페인트 등의 도료는 건축물의 외부 및 내부에 도포되어 외관을 장식함과 함께 방음, 방수, 방진 및 콘크리트의 노화방지 등 여러 기능을 수행할 수 있다. In buildings, paint is applied to decorate the exterior while maintaining a constant indoor temperature as much as possible without being affected by external climatic conditions. Paints such as paint are applied to the exterior and interior of a building to decorate the exterior and perform various functions such as soundproofing, waterproofing, dustproofing, and anti-aging of concrete.
액체 도료의 경우 신나 또는 물을 희석제로 사용하여 붓 등의 도구를 통해 건축물의 일면을 칠하거나 건축물의 일면에 분사하여 도장할 수 있는데 칠한 면이 고르지 못하고 액체 도료를 분사하는 경우 대기중에 도료 성분이 돌아다녀 인체에 유해한 영향을 줄 수 있다. 또한 따라서 도장 시에 과다한 양의 물을 섞어 사용할 경우에는 충분한 두께의 도막이 형성되지 못하거나 페인트가 흘러내리고, 구성 성분(수지, 안료, 첨가제, 물)들간의 분리가 일어나면서 도 1에서와 같이 균일하지 못한 외관이 형성되는 문제가 있다.In the case of liquid paint, thinner or water can be used as a diluent to paint one side of a building with a tool such as a brush or spray it on one side of a building. It can travel around and have harmful effects on the human body. In addition, when an excessive amount of water is mixed and used during painting, a coating film of sufficient thickness cannot be formed or the paint flows down, and the components (resin, pigment, additives, water) are separated and uniform as shown in FIG. There is a problem of forming an undesirable appearance.
이에 반해 분말형 도료의 경우 1회 도포로 소정의 도포 두께를 얻을 수 있으며 도막의 두께가 균일하여 공정이 단축될 수 있고, 일반적으로 스크래치 등의 손상이 잘 발생하지 않는다. 분말을 물 등의 용매에 풀어서 사용하므로 매끄러운 표면을 연출할 수 있다. 그러나 분말형 도료를 도포한 면의 일부분이 노후화되거나 깨져 탈락하는 경우 재시공하더라도 내구성이 떨어지는 문제가 있으며, 혼합되는 조성 및 조성비에 따라 불연성이 잘 발현되지 못하는 문제가 있다.On the other hand, in the case of powder-type paint, a predetermined coating thickness can be obtained with one application, and the process can be shortened because the thickness of the coating film is uniform, and damage such as scratches generally does not occur easily. Since the powder is dissolved in a solvent such as water, a smooth surface can be created. However, when a part of the surface coated with the powder paint is aged or broken and falls off, there is a problem of poor durability even after re-construction, and there is a problem that incombustibility is not well expressed depending on the composition and composition ratio to be mixed.

본 발명에 따른 불연성 분말형 마감재 조성물은 물과 혼합하여 콘크리트, 시멘트 또는 모르타르 등으로 마감된 건축물의 내외벽에 도포하여 사용할 수 있는 것으로, 시멘트, 석고, 수지, 증점제, 분산제, 응결조절제 및 증량제를 비롯한 다양한 성분을 포함할 수 있다. 즉 불연성 분말형 마감재 조성물과 물을 혼합할 때 수화반응을 통해 건축물의 내외벽에 도포될 수 있도록 접착 내지 부착될 수 있으며, 불연성, 내열성, 내화성, 내마모성, 방음성, 방수성 및 내구성이 우수하며 물과 혼합 시 수화반응에 의해 발현되는 접착강도와 건축물의 일면에 도포될 때 작업성이 우수하다.The non-combustible powdery finishing material composition according to the present invention can be used by mixing it with water and applying it to the interior and exterior walls of buildings finished with concrete, cement or mortar, etc. It may contain a variety of ingredients, including That is, when mixing the non-combustible powder-type finishing material composition with water, it can be adhered or attached so that it can be applied to the inner and outer walls of the building through a hydration reaction, and has excellent non-combustibility, heat resistance, fire resistance, abrasion resistance, sound insulation, waterproofness and durability, and has excellent water and water resistance. When mixed, the adhesive strength expressed by the hydration reaction and workability when applied to one side of a building are excellent.
본 발명의 일 실시예에서, 불연성 분말형 마감재 조성물은 분말 상태의 백색 마이크로 시멘트 10~15중량%, 분말 상태의 백색 석고 10~20중량%, 재유화형 분말수지 2~6중량%, 증점제 1~2중량%, 분산제 1~2중량%, 응결조절제 1~2중량% 및 증량제로서 규사 40~60중량%의 조성물을 포함할 수 있다.In one embodiment of the present invention, the non-combustible powdery finishing material composition contains 10 to 15% by weight of white micro cement in powder form, 10 to 20% by weight of white gypsum in powder form, 2 to 6% by weight of redispersible powder resin, and 1 to 1% by weight of thickener. 2% by weight, 1 to 2% by weight of a dispersant, 1 to 2% by weight of a setting control agent, and 40 to 60% by weight of silica sand as an extender.
더욱 바람직하게는, 상기 시멘트는 바람직하게는 10중량%, 상기 석고는 바람직하게는 18중량%, 상기 분말수지는 4중량%의 조성비를 가질 수 있으며, 상기 증점제, 분산제 및 응결조절제는 1.5중량%의 조성비, 증량제는 50%의 조성비를 가질 수 있다. 또한, 상기 구성 외에 건조제, 경화제, 안료 등의 보조적 조성이 추가로 포함될 수도 있다.More preferably, the cement may have a composition ratio of preferably 10% by weight, the gypsum preferably 18% by weight, and the powdered resin 4% by weight, and the thickener, dispersant and setting regulator may have a composition ratio of 1.5% by weight. The composition ratio of, the extender may have a composition ratio of 50%.

상기 시멘트는 물과 수화반응을 통해 본 발명에 따른 불연성 분말형 마감재 조성물의 강도, 지지력, 내구성을 발현한다. 상기 시멘트는 백색의 마이크로 시멘트를 사용하는 것이 바람직다. 마이크로 시멘트는 포틀랜트 시멘트에 비해 순수 무기질계 재료로 저독성의 인체에 무해한 미립형 시멘트이다. 상기 백색 마이크로 시멘트 또는 시멘트 분말은 경화 후 백색의 표면을 가질 수 있으며, 색상을 띈 페인트를 도포하여 외벽 등 표면의 색상을 구현할 수 있다. 도포되는 페인트는 불연성 페인트일 수 있다. 상기 마이크로 시멘트가 물과 수화작용을 통해 접착강도를 발현한다. 상기 시멘트가 접착강도를 발현함에 따라 불연성 분말형 마감재 조성물이 경화 후 건축물의 내외벽에 도포된 상태로 유지될 수 있다.The cement expresses strength, bearing capacity, and durability of the incombustible powdery finishing material composition according to the present invention through a hydration reaction with water. It is preferable to use white micro-cement as the cement. Micro-cement is a pure inorganic material compared to Portland cement, and is a fine-grained cement that is harmless to the human body and has low toxicity. The white micro-cement or cement powder may have a white surface after hardening, and a color of a surface such as an outer wall may be implemented by applying a colored paint. The paint to be applied may be a nonflammable paint. The micro-cement develops adhesive strength through water and hydration. As the cement develops adhesive strength, the incombustible powdery finishing material composition can be maintained in a state of being applied to the inner and outer walls of the building after curing.
상기 시멘트는 상기 불연성 분말형 마감재 조성물에 대하여 10∼20중량% 함유되는 것이 바람직하다. 상기 시멘트의 함량이 10중량% 미만이면 조성물 전반의 결합성과 경화성이 저하되어 접착강도가 저하되며, 15중량% 초과이면 수화반응이 과다하여 작업성이 떨어지는 문제가 있다. 이때 작업성은 작업자가 본 발명에 따른 불연성 분말형 마감재 조성물을 물과 혼합한 후 벽면에 도포할 때 부드럽게 발라지는지 성질을 지칭하며, 작업성이 떨어지는 경우 균일한 도포가 불가능하고 시공기간이 늘어나는 문제가 있다. 상기 시멘트는 더욱 바람직하게는 불연성 분말형 마감재 조성물에 대하여 10중량% 포함될 수 있다.The cement is preferably contained in an amount of 10 to 20% by weight based on the incombustible powdery finishing material composition. If the content of the cement is less than 10% by weight, the overall bonding and curing properties of the composition are lowered, resulting in a decrease in adhesive strength. At this time, workability refers to the property of smooth application when a worker mixes the incombustible powder-type finishing material composition according to the present invention with water and then applies it to a wall surface. If workability is poor, uniform application is impossible and the construction period is extended. there is. The cement may be more preferably included in an amount of 10% by weight based on the non-combustible powdery finishing material composition.
상기 석고는 건조수축에 의한 균열을 저감하고 강도 발현을 개선하기 위하여 사용될 수 있다. 상기 석고는 분말 형태로 혼합될 수 있다. 석고 분말로 무수석고가 사용될 수 있으나, 반수석고가 사용될 수도 있다. 상기 석고 분말은 백색의 색상을 가질 수 있다. 시멘트 분말의 경우와 같이 상기 석고 분말이 백색을 가짐에 따라 물과 혼합하여 경화 후 별도로 페인트를 도포하여 색상을 구현할 수 있다. 상기 석고는 상기 불연성 분말형 마감재 조성물에 대하여 10∼20중량% 함유되는 것이 바람직하다. 상기 석고의 함량이 10중량% 미만이면 조성물 전반의 작업성이 용이하지 않으며 접착강도가 저하되어 균열 저감 및 강도 발현 효과가 미약할 수 있고, 20중량%를 초과하여 과량 혼합되면 뭉침현상으로 점도가 상승하여 오히려 재료 간 분리현상이 발생될 수 있고 건조 시 빠른 건조로 도막의 균열 및 박리현상이 발생할 수 있다. 상기 석고는 더욱 바람직하게는 불연성 분말형 마감재 조성물에 대하여 18중량% 포함될 수 있다.The gypsum may be used to reduce cracks due to drying shrinkage and improve strength expression. The gypsum may be mixed in powder form. Anhydrite may be used as the gypsum powder, but hemihydrate gypsum may also be used. The gypsum powder may have a white color. As in the case of cement powder, since the gypsum powder has a white color, it can be mixed with water and cured, and then separately applied with paint to realize color. The gypsum is preferably contained in an amount of 10 to 20% by weight based on the incombustible powdery finishing material composition. If the content of the gypsum is less than 10% by weight, the overall workability of the composition is not easy, and the adhesive strength is lowered, so the effect of reducing cracks and developing strength may be insignificant. As it rises, separation between materials may occur, and cracks and peeling of the coating film may occur due to rapid drying during drying. The gypsum may be more preferably included in an amount of 18% by weight based on the non-combustible powdery finishing material composition.
종래 분말형 마감재의 경우 물과 혼합하였을 때 벽면에 도포하고 경화시키기 위하여, 접착강도를 발현하도록 수지를 약 10중량% 이상, 바람직하게는 약 15~20중량%까지 포함하는 경우가 있다. 그러나 이와 같은 수지는 통상적으로 가연성 소재이기 때문에 화재발생 시 불에 타는 문제가 있고 불연성 시험을 통과하지 못하는 경우가 있다. 따라서 본 발명은 가연성의 수지를 통해 접착강도를 발현시키는 대신, 분말 시멘트와 분말 석고의 수화반응을 통해 접착강도를 발현시키면서 후술하는 바와 같이 재유화형 분말수지를 포함하도록 하여 적절한 접착강도를 발현시키면서 마감재 조성물의 불연성을 획득할 수 있다.In the case of a conventional powder-type finishing material, it may contain about 10% by weight or more, preferably about 15 to 20% by weight of a resin to develop adhesive strength in order to be applied to the wall surface and cured when mixed with water. However, since such a resin is usually a combustible material, there is a problem of burning in the event of a fire and may not pass the non-combustibility test. Therefore, the present invention, instead of expressing adhesive strength through a flammable resin, expresses adhesive strength through a hydration reaction between powdered cement and powdered gypsum and includes a re-emulsifying powdered resin as described later to develop a suitable adhesive strength while developing a finishing material. Incombustibility of the composition can be obtained.
상기 분말수지는 재유화형 분말수지가 사용될 수 있다. 재유화형 분말수지(EVA 분말수지)는 물에 용이하게 분산되는 EVA(ethylene vinyl acetate) 공중합 폴리머 분말수밀성 향상이 유리하며 접착강도를 추가적으로 높이기 위해 사용될 수 있다. 상기 재유화형 분말수지는 가연성인 경우 과량 혼합되면 불연성 분말형 마감재 조성물의 불연성을 저하시킬 수 있으므로 불연성 분말형 마감재 조성물에 대하여 2~6중량% 혼합됨이 바람직하다. 상기 분말수지가 2중량%보다 적게 혼입되는 경우 혼합이 원활하지 않아 접착강도가 저하될 수 있으며, 6중량%를 초과하여 과량 혼합되는 경우 분말수지가 시멘트와 결합하지 못하고 남아돌아 강도저하를 유발하며 불연성이 저하될 수 있다. 상기 분말수지는 더욱 바람직하게는 불연성 분말형 마감재 조성물에 대하여 4중량% 포함될 수 있다.The powdered resin may be a re-emulsifying powdered resin. Re-emulsifying powder resin (EVA powder resin) is advantageous in improving watertightness of EVA (ethylene vinyl acetate) copolymer powder, which is easily dispersed in water, and can be used to further increase adhesive strength. The re-emulsifying powder resin is preferably mixed in an amount of 2 to 6% by weight with respect to the non-flammable powder-type finishing material composition because excessive mixing of the flammable resin may reduce the incombustibility of the non-flammable powder-type finishing material composition. When the powdered resin is mixed in less than 2% by weight, the mixing is not smooth and the adhesive strength may be lowered. Incombustibility may be reduced. The powdered resin may be more preferably included in an amount of 4% by weight based on the non-combustible powdery finishing material composition.
상기 증점제는 불연성 분말형 마감재 조성물이 물과 혼합되었을 때 점성을 증가시키기 위해 사용될 수 있다. 물과 혼합하여 벽면 등에 도장되는 본 발명에 따른 불연성 분말형 마감재 조성물은 도장시에는 겉보기점도가 낮아 도장이 용이하며, 도장 후 적당한 도막두께를 유지하며 흐르지 않음이 바람직하다. 물과 혼합된 불연성 분말형 마감재 조성물이 벽에 달라붙게 하기 위해서 점도가 필요하다. 상기 증점제는 합성미분 실리카계, 유기벤토나이트계, 산화 폴리에틸렌계 증점제가 사용될 수 있으며, 상술한 증점제 외에 다른 성분으로 이루어진 공지된 증점제가 사용될 수도 있다. The thickener may be used to increase the viscosity of the non-combustible powdery finish composition when mixed with water. The incombustible powdery finishing material composition according to the present invention, which is mixed with water and painted on a wall surface, has a low apparent viscosity during painting, and is easy to paint, and it is preferable that it does not flow while maintaining an appropriate film thickness after painting. A non-combustible powdered finish composition mixed with water needs viscosity to make it stick to the wall. As the thickener, a synthetic fine powder silica-based, organic bentonite-based, or oxidized polyethylene-based thickener may be used, and a known thickener composed of other ingredients may be used in addition to the above-mentioned thickener.
상기 증점제는 불연성 분말형 마감재 조성물에 대하여 1~2중량% 혼합됨이 바람직하다. 증점제가 1중량%보다 적게 혼합되는 경우 조성물의 작업가능시간이 짧아지며 물에 대한 흡수계수가 높아지는 문제가 있으며, 2중량%보다 과량 혼합되는 경우 조성물의 점도가 높아져 작업성이 현저히 저하되는 문제가 있다. 상기 증점제는 더욱 바람직하게는 불연성 분말형 마감재 조성물에 대하여 1.5중량% 포함될 수 있다.The thickener is preferably mixed in an amount of 1 to 2% by weight based on the non-combustible powdery finishing material composition. When the thickener is mixed in less than 1% by weight, the workable time of the composition is shortened and the water absorption coefficient is increased. there is. The thickener may be more preferably included in an amount of 1.5% by weight based on the non-combustible powdery finishing material composition.
상기 분산제는 분말 상태의 시멘트와 석고 등을 물과 혼합할 때 뭉침현상을 방지하도록 혼합될 수 있다. 불연성 분말형 마감재 조성물을 물에 혼합한 후 작업자가 쇠흙손 등 도구를 통해 벽에 바르는데, 분산제를 통해 분말상태의 조성물들이 물 안에서 충분히 분산되어야 작업이 원활하게 진행될 수 있다.The dispersant may be mixed to prevent agglomeration when powdered cement and gypsum are mixed with water. After mixing the non-combustible powdery finishing material composition with water, the worker applies it to the wall using a tool such as an iron trowel.
상기 분산제는 불연성 분말형 마감재 조성물에 대하여 1~2중량% 혼합됨이 바람직하다. 분산제가 1중량%보다 적게 혼합되는 경우 조성물의 작업성이 현저히 저하되며 경화속도가 빨라지고 접착강도가 저하되는 문제가 있으며, 2중량%보다 과량 혼합되는 경우 조성물이 묽어져 재료분리가 발생하는 문제가 있다. 상기 분산제는 더욱 바람직하게는 불연성 분말형 마감재 조성물에 대하여 1.5중량% 포함될 수 있다.The dispersant is preferably mixed in an amount of 1 to 2% by weight based on the non-combustible powdery finishing material composition. When the dispersant is mixed in less than 1% by weight, the workability of the composition is significantly deteriorated, and the curing speed is increased and the adhesive strength is lowered. there is. The dispersant may be more preferably included in an amount of 1.5% by weight based on the non-combustible powdery finishing material composition.
상기 응결조절제는 시멘트의 고형화를 지연시켜 작업을 원활하게 할 수 있도록 혼합될 수 있다. 시멘트와 석고가 수화반응에 따라 조기에 경화되는 경우 충분한 작업이 불가능하므로 응결조절제에 의해 경화가 조절될 수 있다. The setting control agent may be mixed to delay the solidification of cement to facilitate work. When cement and gypsum harden early due to hydration, sufficient work is not possible, so hardening can be controlled by setting regulators.
상기 응결조절제는 불연성 분말형 마감재 조성물에 대하여 1~2중량% 혼합됨이 바람직하다. 응결조절제가 1중량%보다 적게 혼합되는 경우 조성물의 응결시간이 빨라져 작업가능시간이 짧아지는 문제가 있으며, 2중량%보다 과량 혼합되는 경우 조성물의 경화가 지연되며 벽면에 대한 부착력 저하가 발생하는 문제가 있다. 상기 응결조절제는 더욱 바람직하게는 불연성 분말형 마감재 조성물에 대하여 1.5중량% 포함될 수 있다.The setting control agent is preferably mixed in an amount of 1 to 2% by weight based on the non-combustible powdery finishing material composition. When the setting control agent is mixed in less than 1% by weight, the setting time of the composition is accelerated and the workable time is shortened, and when mixed in an excessive amount than 2% by weight, the curing of the composition is delayed and the adhesion to the wall is reduced. there is The setting control agent may be more preferably included in an amount of 1.5% by weight based on the non-combustible powdery finishing material composition.
상기 증량제는 규사가 사용될 수 있다. 불연성 분말형 마감재 조성물에 규사가 혼합되어 경화 후 표면에 불규칙한 패턴이 형성될 수 있다. 소정 입경의 규사가 증량제로 혼합됨에 따라 상기 규사에 의해 도 2에서 볼 수 있는 바와 같이 불규칙한 표면 질감을 형성할 수 있다. 상기 증량제는 불연성 분말형 마감재 조성물에 대하여 40~60중량% 혼합됨이 바람직하다. 증량가 40중량%보다 적게 혼합되는 경우 조성물의 작업성이 저하되고 균열이 발생하는 문제가 있으며, 60중량%보다 과량 혼합되는 경우 조성물의 습윤성이 부족하여 작업성이 저하되고 부착력이 저하되는 발생하는 문제가 있다. 상기 증량제는 더욱 바람직하게는 불연성 분말형 마감재 조성물에 대하여 50중량% 포함될 수 있다. 상기 규사의 입경은 1~2mm인 것으로 불규칙한 패턴을 형성하는 것이 바람직하다.As the extender, silica sand may be used. An irregular pattern may be formed on the surface after curing by mixing silica sand with the incombustible powdery finishing material composition. As silica sand having a predetermined particle size is mixed with the extender, an irregular surface texture may be formed by the silica sand, as shown in FIG. 2 . The extender is preferably mixed in an amount of 40 to 60% by weight based on the non-combustible powdery finishing material composition. When the increase amount is less than 40% by weight, the workability of the composition deteriorates and cracks occur, and when the amount is mixed in excess of 60% by weight, the wettability of the composition is insufficient, resulting in deterioration of workability and deterioration of adhesion. there is The extender may be more preferably included in an amount of 50% by weight based on the non-combustible powdery finishing material composition. The silica sand has a particle diameter of 1 to 2 mm, and it is preferable to form an irregular pattern.
본 발명의 바람직한 일 실시예에서는 불연성 분말형 마감재 조성물 100 중량부 대비 물 20.5 중량부를 배합한 후 쇠흙손을 사용하여 벽면 또는 건축물의 일면에 일정한 두께로 펴바르는 방법으로 시공이 가능하다.In a preferred embodiment of the present invention, construction is possible by mixing 20.5 parts by weight of water with respect to 100 parts by weight of the non-combustible powdery finishing material composition and then spreading it to a certain thickness on a wall surface or one side of a building using an iron trowel.
본 발명에 따른 불연성 분말형 마감재 조성물은 기존의 분말형 페인트와 달리 불연성이 우수할 뿐만 아니라 재유화형 분말수지, 증점제, 응결조절제의 배합을 통해 작업성과 접착강도가 우수하며, 증량제로서 소정 입도를 가진 규사를 혼합하여 경화 후 불규칙한 표면을 발현시킬 수 있다.The incombustible powder-type finishing material composition according to the present invention not only has excellent incombustibility, unlike conventional powder-type paints, but also has excellent workability and adhesive strength through the combination of a re-emulsifying powder resin, a thickener, and a setting control agent, and has a predetermined particle size as an extender. An irregular surface can be developed after curing by mixing silica sand.

[비교예 2][Comparative Example 2]
분말상태의 백색 마이크로시멘트 10중량%, 분말상태의 백색 석고 18중량%, 증점제 1.5중량%, 분산제 1.5중량%, 응결조절제 1.5중량%, 증량제 50중량%를 포함하는 불연성 분말형 마감재 조성물을 물과 혼합하여 벽면에 도포한 후 경화시켜 접착강도를 측정하여 0.6MPa의 접착강도가 측정되었다.

각 실시예 및 비교예에서 측정된 접착강도는 하기의 표 1과 같다.The adhesive strength measured in each Example and Comparative Example is shown in Table 1 below.
시멘트와 석고 및 분말수지의 조성비에 따라 접착강도가 크게 변화하는 것을 확인할 수 있다. 특히 시멘트의 조성비가 10중량%보다 작은 경우 접착강도가 크게 저하되며, 석고는 바람직한 범위 내 조성비가 아닌 경우 접착강도가 저하되는 것을 확인할 수 있다. 분말수지나 증점제가 과량 혼합되는 경우 시멘트 및 석고와 물의 수화반응을 저해하여 접착강도가 크게 저하되고, 증량제가 60중량%를 초과하여 혼합되는 경우 증량제에 의해 수화반응이 저하되어 접착강도가 저하되는 문제가 있다.It can be seen that the adhesive strength varies greatly depending on the composition ratio of cement, gypsum and powdered resin. In particular, when the composition ratio of cement is less than 10% by weight, the adhesive strength is greatly reduced, and when the composition ratio of gypsum is not within the desired range, it can be seen that the adhesive strength is reduced. When an excessive amount of powdered resin or thickener is mixed, the hydration reaction between cement and gypsum and water is inhibited, resulting in a significant decrease in adhesive strength. there is a problem.
특히, 석고 또는 재유화형 분말수지를 포함하지 않고 혼합된 불연성 분말형 마감재 조성물의 경우, 석고의 수화반응이 결여되거나 재유화형 분말수지가 시멘트 및 석고의 원활한 수화반응을 보조하지 못하여 접착강도가 크게 저하됨을 확인할 수 있다. 본 발명의 바람직한 실시예의 경우 접착강도가 우수하고, 점성 등 작업성이 우수하여 작업자가 충분한 작업시간을 가지고 벽면에 불연성 분말형 마감재 조성물을 도포할 수 있다.In particular, in the case of a mixed non-combustible powdery finishing material composition without gypsum or re-emulsification type powder resin, the hydration reaction of gypsum is lacking or the re-emulsification type powder resin does not support the smooth hydration reaction of cement and gypsum, so the adhesive strength is greatly reduced. can confirm. In the case of a preferred embodiment of the present invention, the adhesive strength is excellent, and the workability such as viscosity is excellent, so that the operator can apply the incombustible powder-type finishing material composition to the wall surface with sufficient working time.
