Description

난연성 바닥 마감재 조성물{A noninflammability finish-meterial composition for floor}A noninflammability finish-meterial composition for floor

본 발명은 난연성 바닥 마감재 조성물에 관한 것으로, 좀 더 상세하게는 화재에 대한 내화성이 좋고 유해가스나 냄새가 배출되지 않아 화재시 건물과 인명의 피해를 최소화할 수 있는 난연성 바닥 마감재 조성물에 관한 것이다.The present invention relates to a flame retardant floor finish composition, and more particularly to a flame retardant floor finish composition that can minimize the damage to buildings and human life in the event of fire is not good fire resistance and no harmful gases or odors emitted.

건축구조물의 바닥은 그 사용목적이나 용도에 따라 다양한 성능이 요구되기 때문에 이를 만족시키기 위해 바닥의 구조재 및 바닥바탕에 적절한 재질의 마감재를 선택하여 적절한 공법으로 시공해야 한다. Since floors of building structures require various performances depending on their purpose or use, the floorings of building structures should be selected and constructed by appropriate construction methods to satisfy the structural requirements of floors and flooring materials.

이러한 바닥 마감재는 재질별로 보면, 목질재 석재, 합성수지재, 고무재, 요업의 마감재를 선택하여 적절한 공법으로 시공되고 있으며, 이를 공법별로 살펴보면 크게 붙임재와 바름재와 같이 두가지로 대별될 수 있다. These floor finishing materials are selected by wood materials, synthetic resins, rubber materials, ceramics finishing materials are selected by the appropriate construction method, if you look at the construction method can be roughly divided into two types, such as paste and varnish.

먼저, 붙임재 공법은 균일한 치수로 공장에서 대량으로 생산할 수 있는 제품으로, 못을 박거나 접착제에 의해 붙여주는 것이기에 일반적으로 시공이 간편하고 공사기간이 짧으나, 공법이 적절하지 않으면 박리나 이음매에 공극이 생기기 쉬운 결점이 있다. 이에 반해 바름재 공법은 이음매가 없고 평활하게 마감되는 장점이 있으나, 일반적으로 시공이 어렵고 공사기간이 길며 재료에 따라서는 균열이 발생되는 결점이 있다.First, the glue material method is a product that can be produced in large quantities in the factory with uniform dimensions.It is usually easy to construct and short in construction period because it is attached by nailing or adhesive. There is a flaw that is easy to form voids. On the other hand, the coating method has the advantage of seamless and smooth finish, but generally has a drawback of difficult construction, long construction period and cracking depending on the material.

따라서, 상기한 바와 같이 바닥 마감재는 각각 일장일단이 있으므로, 건축구조물 바닥의 사용목적이나 용도에 따른 내구성, 기능성, 장식성 등의 성능과 시공성을 고려하여 적절한 바닥마감재와 시공방법을 선택하여 왔다.Therefore, as described above, since the floor finishing materials are finished, the appropriate floor finishing materials and construction methods have been selected in consideration of performance and construction properties such as durability, functionality, and decoration according to the purpose or purpose of the building structure floor.

현재 바름재의 대표적인 제품으로는 모르타르 또는 인조석과 같은 요업제품이 가장 많이 사용되고 있으며, 이는 천연 석재류에 비해 가격이 저렴하면서도 천연 석재류의 외관효과를 발휘하며, 뛰어난 내구성과 함께 편리한 시공성을 가지기 때문이다.Currently, ceramic products such as mortar or artificial stone are most commonly used as the representative products of Baumjae, because they are inexpensive compared to natural stones and exhibit the appearance effect of natural stones and have excellent durability and convenient construction. .

상기 모르타르(Mortar)는 대개 건축 현장에서 골재와 시멘트를 임의의 비율로 혼합하고 여기에 물을 혼합하여 어느 정도의 점도를 부여한 시멘트 조성물로서, 여러 가지 마감기구를 통하여 바닥에 시공한 후 일정한 양생기간을 거쳐 경화 및 건조시키면서 강도를 발휘해 마감재로서의 효용성을 갖도록 한다. The mortar is a cement composition in which aggregates and cement are mixed at an arbitrary ratio at a construction site and water is mixed therewith to give a certain viscosity, and a fixed curing period after construction on the floor through various finishing mechanisms It exhibits strength while hardening and drying through it to have utility as a finishing material.

한편, 초기의 시멘트 모르타르는 시멘트 수화물의 고유 특성인 경화시 건조 수축으로 인해 크랙, 박리현상 등이 발생되거나, 잦은 차량 및 사람의 통행으로 인해 내구성이 약하다는 문제점을 안고 있었으며, 이에 최근에는 에폭시 수지 계열의 유기화합물을 결합제로 사용한 유기 바닥 마감재가 일반적으로 사용되고 있다.On the other hand, the early cement mortar had problems such as cracks, peeling phenomenon due to dry shrinkage during curing, which is an inherent property of cement hydrate, or weak durability due to frequent traffic of vehicles and people. Organic floor finishes using a series of organic compounds as binders are commonly used.

이러한 유기 바닥 마감재는 유기화합물을 단독으로 사용되지 않고 경화제를 함께 첨가하여 열경화성 물질로 변화시킨 상태로서 사용되는 것이 보통이며, 그 외 에도 안정제나 소포제, 감수제와 같은 다수의 유기첨가제가 함께 사용되고 있다.Such organic floor finishes are generally used as a state in which the organic compound is not used alone, but is added as a curing agent and changed into a thermosetting material. In addition, many organic additives such as stabilizers, antifoaming agents, and water reducing agents are used together.

그러나, 이러한 유기 바닥 마감재는 화재시 결합제를 비롯한 각종 첨가제로 사용된 유기물들이 불에 의해 연소되어 각종 독성의 가스를 발생시키게 되며, 이로 인하여 화재에 의한 피해가 심각해지기 때문에 건물과 인명을 보호하기 위한 내화성이 요구되고 있는 실정이다.However, in the case of the organic floor finishing material, the organic materials used as various additives including the binder are burned by the fire to generate various toxic gases. Fire resistance is required.

또한, 종래의 바닥 마감재 조성물은 대부분이 2액형의 용액상태로 보관 및 운반되며, 이에 작업현장에서 각 원료들을 일일이 배합비율에 맞춰 혼합해야 하기 때문에 작업성이 떨어질 뿐만 아니라 시공시간도 길어져 전체적인 작업효율이 낮다는 문제점이 있었다. In addition, most of the conventional floor finishing composition is stored and transported in a two-component solution state, and at the work site, each raw material must be mixed in accordance with the blending ratio, which reduces workability and lengthens the construction time, resulting in overall work efficiency. There was a problem that this was low.

따라서 본 발명은 상기와 같은 문제점을 해결하기 위하여 구성된 것으로, 화재에 대한 내화성이 좋고 유해가스나 냄새가 배출되지 않아 화재시 건물과 인명의 피해를 최소화할 수 있는 난연성 바닥 마감재 조성물을 제공하는 것을 목적으로 한다.Accordingly, the present invention has been made to solve the above problems, the object of providing a flame retardant floor finish composition that can minimize the damage to buildings and human life in the event of fire is not fire-resistant good toxic gas or odor is not emitted. It is done.

상기와 같은 목적을 달성하기 위하여 본 발명은,The present invention to achieve the above object,

Is achieved.

아울러, 본 발명은 전술한 바닥 마감재 조성물을 준비하는 단계와; 상기 바닥 마감재 조성물 100중량부를 분무장치에 투입하고 물 5~20중량부를 추가로 투입한 다음 교반하는 단계와; 상기 물과 교반된 바닥 마감재 조성물을 분무장치를 통해 시공하고자 하는 건축물 바닥면에 분무시키는 단계와; 상기 분무된 바닥 마감재 조성물이 완전히 경화될 때 까지 건조시키는 단계;로 구성된 것을 특징으로 하는 난연성을 갖는 바닥 마감재의 시공방법을 제공한다.In addition, the present invention comprises the steps of preparing the above-described floor finishing composition; Adding 100 parts by weight of the bottom finishing material composition to a spray device, and further adding 5 to 20 parts by weight of water, followed by stirring; Spraying the water and the stirred floor finish composition onto a building floor to be constructed through a spray device; The sprayed floor finish composition is dried until it is completely cured; provides a construction method of the floor finish having a flame retardancy, characterized in that consisting of.

상술한 바와 같이 본 발명의 난연성 바닥 마감재 조성물은 그 구성원료로서 최대한 난연성을 고려하여 선택 및 배합하고, 특히 규산칼슘(CaSiO3)계 광물섬유를 추가로 첨가함에 따라 종래 바닥 마감재로서의 물성을 그대로 유지하면서도 전체적인 난연성을 효율적으로 향상시켜 화재시 유해가스나 냄새가 배출되지 않고 건물과 인명의 피해를 최소화할 수 있는 효과를 가져온다.As described above, the flame retardant floor finishing composition of the present invention is selected and blended in consideration of flame retardancy as much as possible as its component, and in particular, the physical properties of the conventional floor finishing are maintained as additional calcium silicate (CaSiO 3 ) mineral fiber is added. At the same time, it effectively improves the overall flame retardancy, so that no harmful gases or odors are emitted in the event of fire, thereby minimizing damage to buildings and lives.

아울러, 본 발명의 바닥 마감재 조성물은 그 원료들이 모두 상온에서 고상으로 존재하기 때문에 물이 투입되기 전까지는 서로 반응되지 않아, 상기 원료들이 하나의 포장지에 모두 혼합된 상태로 생산이 가능하기 때문에 운반 및 보관이 용이할 뿐만 아니라 시공현장에서 일일이 상기 원료들을 배합하지 않고 바로 시공이 가능하므로 작업효율 향상 및 시공시간의 단축과 같은 효과도 가져온다. In addition, the floor finishing composition of the present invention do not react with each other until the water is added because all of the raw materials are present in a solid state at room temperature, the raw materials are transported because they can be produced in a mixed state in one wrapping paper Not only is it easy to store, but also can be installed immediately without mixing the raw materials at the construction site, thereby bringing effects such as improvement in work efficiency and construction time.

이하에서는 본 발명에 대하여 좀 더 상세하게 설명하기로 한다.Hereinafter, the present invention will be described in more detail.

본 발명의 난연성 바닥 마감재 조성물은 포틀랜드 시멘트와 실리카 샌드, 무정형 실리카 분말, 아크릴 수지 분말, 규산칼슘(CCaSiO3)계 광물섬유, 양생촉진제, 증점제, 감수제, 소포제를 적정배합범위로 혼합하여 더욱 향상된 난연성을 갖는 것 을 특징으로 한다.The flame retardant flooring composition of the present invention further improves flame retardancy by mixing Portland cement with silica sand, amorphous silica powder, acrylic resin powder, calcium silicate (CCaSiO 3 ) -based mineral fiber, curing accelerator, thickener, water reducing agent, and antifoaming agent in an appropriate mixing range. It is characterized by having.

상기와 같은 바닥 마감재 조성물의 구성요소 중에서, 먼저 포틀랜트 시멘트로는 각 원료를 교착시키는 기능을 수행하게 되는데, 주로 바름공사에 사용되는 백(白)시멘트가 가장 바람직하게 사용되며, 이는 백(白)시멘트를 사용함으로써 추가적인 색상안료의 색상이 뚜렷하게 발현할 수 있도록 하기 위함이다. 이러한 포틀랜트 시멘트는 시공이 이루어지는 바탕층과의 부착성 및 내마모성을 고려하여 그 사용함량을 전체 조성물에 대해 40~50중량부가 사용된다.Among the components of the floor finishing composition as described above, first, the port cement is to perform the function of interlacing each raw material, the white cement mainly used in the coating work is most preferably used, which is the white (白) This is to make the color of additional color pigments appear clearly by using cement. The portland cement is used in the amount of 40 to 50 parts by weight based on the total composition in consideration of adhesion and wear resistance to the base layer on which the construction is made.

골재로는 주로 일반 바닷가에서 사용되는 모래가 사용되고 있으나, 본 발명에서는 내화성을 향상시키기 위한 목적에 부합하기 위하여 실리카 샌드(silica sand)가 바람직하게 사용되며, 이러한 실리카 샌드는 시공단계에서 바닥 마감재의 밀도를 기밀하게 해준다. 그 사용함량은 시공바탕면인 콘크리트와 부착안정성을 높여 균열이 발생하지 않는 범위 내에서 첨가되며, 이에 전체 조성물에 대해 23~28중량부가 사용된다. 이 때 사용되는 실리카 샌드는 60메쉬(mesh)의 것이 바람직하게 사용된다.As the aggregate, sand used for general beaches is used, but in the present invention, silica sand is preferably used in order to meet the purpose of improving fire resistance, and such silica sand has a density of floor finishing material during construction. To keep it confidential. The used content is added within the range that the cracks do not occur to increase the adhesion stability with the concrete, the construction surface, this is used 23 to 28 parts by weight based on the total composition. The silica sand used at this time is preferably of 60 mesh.

상기 포틀랜트 시멘트와 골재의 사용함량은 토목 및 건축 분야의 구조물에 대한 표준 함량 규정에 의거하여 제시된다.The content of the Portland cement and aggregates is presented based on standard content provisions for structures in the civil and building sectors.

무정형 실리카 분말은 포틀랜트 시멘트의 석회분과 반응을 일으켜 바닥 마감재 자체의 경화를 촉진함과 동시에 바닥바탕에 부착할 때는 시멘트 바탕의 유리석회 성분과 반응을 일으켜 바닥바탕의 미세한 공극 내부에 미립자인 규산석회의 침상결정을 형성함으로써 부착력을 강화시키는 기능을 수행한다. 상기한 실리카 분말 은 전체 조성물에 대해 15~20중량부가 첨가되며, 이러한 첨가량은 포틀랜트 시멘트의 사용함량에 비례하는 것으로서 토목 및 건축자재의 표준 함량 규정에 따른 것이다.Amorphous silica powder reacts with the lime powder of portland cement to promote hardening of the floor finish itself, and when attached to the floor, it reacts with the glass-based lime component of the cement to form fine particles in the pores of the floor. It forms a needle-like crystal of to strengthen the adhesion. The silica powder is added in an amount of 15 to 20 parts by weight based on the total composition, which is proportional to the amount of portland cement used in accordance with the standard content of civil engineering and building materials.

결합제로 사용되는 수용성 아크릴 수지는 분말(Powder) 형태의 것이 작업성 및 보관성이 좋아 바람직하게 사용되며, 이러한 아크릴 수지는 바닥 마감재 조성물에 흡수성 및 내마모성 및 신축성을 부여하는 동시에, 바닥 마감재 자체로 하여금 음이온성을 띄게 함으로써 양이온성인 아크릴 수지 결합재와 이온교환에 따른 안정적인 부착강도를 나타내도록 한다. 상기 아크릴 수지는 전체 조성물에 대해 5~8중량부가 첨가되며, 이는 상기 범위보다 적게 첨가되면 전술한 효과가 미약하게 나타나며, 상기 범위보다 많이 첨가되면 오히려 바닥 마감재의 부착강도를 떨어뜨리기 때문이다. The water-soluble acrylic resin used as a binder is preferably used in powder form because of its workability and storage property. The acrylic resin provides the floor finishing composition with absorbency and wear resistance and elasticity, By making it anionic, it exhibits stable adhesion strength due to ion exchange with the cationic acrylic resin binder. The acrylic resin is added to 5 to 8 parts by weight based on the total composition, because if the addition is less than the above-mentioned range is a slight effect, the addition of more than the above-mentioned range is rather lower the adhesive strength of the floor finish.

규산칼슘(CaSiO3)계 광물섬유는 본 발명의 바닥 마감재 조성물의 난연성을 증대시키는 중요한 역할을 수행하게 되는데, 이러한 광물섬유는 미네랄 울(Mineral fiber)이라고도 불리우며 천연적으로 얻어지는 석면이나 과학적으로 만들어진 인공암면, 글라스 울 등이 있으며, 주로 보온이나 방음재로 사용되어 온 제품이다.Calcium silicate (CaSiO 3 ) -based mineral fiber plays an important role in increasing the flame retardancy of the floor finishing composition of the present invention, which is also called mineral fiber (Mineral fiber), naturally obtained asbestos or scientifically made artificial Rock wool, glass wool, etc. are mainly used as insulation or sound insulation.

그러나, 본 발명에서는 상기한 광물섬유 중에서도 규산칼슘(CaSiO3)으로 이루어진 것을 바닥 마감재 조성물에 일정량 첨가하였을 경우 그 재질상 난연성이 향상됨을 실험적으로 확인할 수 있었으며, 특히 포틀랜트 시멘트의 주요성분과 같기 때문에 조성물의 접착강도를 저해시키지 않을 뿐만 아니라 오히려 경화 후 표면에 크랙이 발생되는 것을 방지할 수 있다.However, in the present invention, when a certain amount of calcium silicate (CaSiO 3 ) made of the above mineral fiber was added to the floor finishing composition, it was experimentally confirmed that the flame retardancy of the material was improved, and in particular, the same as the main component of portland cement. Not only does not impair the adhesive strength of the composition, but can also prevent the occurrence of cracks on the surface after curing.

이러한, 규산칼슘(CaSiO3)계 광물섬유는 전체 조성물에 대해 1~5중량부가 첨가되는 것이 바람직하며, 이는 상기 범위보다 적게 첨가될 경우 시공된 바닥 마감재에 만족할만한 난연성을 나타낼 수 없으며, 반대로 상기 범위보다 많이 첨가되어도 더 이상의 증진된 효과는 나타나지 않기 때문에 상기 범위 내에서 첨가되는 것이 바람직하다. The calcium silicate (CaSiO 3 ) -based mineral fiber is preferably added 1 to 5 parts by weight based on the total composition, which may not exhibit satisfactory flame retardancy to the floor finish constructed when added less than the above range, on the contrary It is preferable to add in the above range because more enhanced effects do not appear when added in more than the range.

상기 실시예 1 내지 5의 방법에 의해 시공된 바닥 마감재에 대하여 한국건자재시험연구원으로부터 건설교통부 고시 제2006-476호(KS F ISO 1182:2004)에서 규정하는 방법에 따라 불연성 시험하였으며, 이와 함께 건설교통부 고시 제2006-476호(KS F 2271:2006)에서 규정하는 방법에 따라 가스 유해성 시험하여 그 결과를 하기 표 1에 나타내었다.The floor finishing materials constructed by the methods of Examples 1 to 5 were tested for incombustibility according to the method specified in the Ministry of Construction and Transportation Notice No. 2006-476 (KS F ISO 1182: 2004) from the Korea Construction Materials Testing Institute. The gas hazard test was conducted in accordance with the method specified in the Ministry of Transportation Notification 2006-476 (KS F 2271: 2006), and the results are shown in Table 1 below.

-불연성 시험-Non-flammability test

각 실시예의 바닥 마감재로 부터 지름 45㎜, 두께 48㎜의 원판형의 시편을 채취하고, 상기 시편에 20분 동안 800℃의 열을 가한 다음, 최초 바닥 마감재의 질량과 가열한 후 바닥 마감재의 질량을 비교하여 그 감소율(%)을 측정하였고, 가열 과정에서 바닥 마감재의 최고온도와 최종 평형온도의 차이를 측정하여 온도편차(K)로 나타내었다.A circular specimen of 45 mm diameter and 48 mm thickness was taken from the floor finish of each example, heated to 800 ° C. for 20 minutes, and then heated with the mass of the first floor finish and the mass of the floor finish after heating. The reduction rate (%) was measured by comparing and, and the difference between the maximum temperature and the final equilibrium temperature of the floor finishing material during the heating process was measured and expressed as a temperature deviation (K).

-가스유해성 시험- Gas Hazard Test

각 실시예의 바닥 마감재로부터 220㎜×220㎜×6.1㎜의 판상의 시편을 채취하고, 상기 시편들을 15분 동안 가열하여 이로부터 배출되는 가스들이 유입될 수 있는 공간 내에 ICR계 암컷 흰쥐 10마리의 평균행동정지시간을 측정하여 가스유해성을 판단하였다.

상기 표 1에 나타난 바와 같이, 실시예 2 내지 5의 바닥 마감재는 한국건자재 시험연구원으로부터 상기 시험결과에 따라 불연재료의 기준에 적합한 것으로 판명되었으며, 이에 반하여 실시예 1의 바닥 마감재의 경우에는 상대적으로 질량감소율이나 온도편차에서 많은 차이를 보이면 불연성 재료로 적합하지 못함을 알 수 있다.As shown in Table 1, the floor finishing materials of Examples 2 to 5 were found to meet the criteria of non-combustible materials according to the test results from the Korea Building Materials Testing Institute, on the other hand, in the case of the floor finishing materials of Example 1 Many differences in mass loss rate or temperature drift can be seen as unsuitable for incombustible materials.

아울러, 가스유해성 시험에서도 실시예 2 내지 5의 경우에는 시험에 사용된 흰쥐들이 모두 15분 내외의 생존율을 보이는 반면에, 실시예 1의 경우에는 상대적으로 매우 짧은 시간 내에 흰쥐들이 모두 죽은 것으로 밝혀졌으며, 이는 바닥마감재로부터 다량의 유해가스가 생성되었기 때문임을 알 수 있다. In addition, in the gas hazard test, all of the rats used in the test of Examples 2 to 5 showed a survival rate of about 15 minutes, whereas in Example 1, all the rats were found to die within a relatively very short time. , It can be seen that a large amount of harmful gas generated from the floor finish material.

다만, 실시예 5의 경우 불연성과 가스 유해성시험에서 모두 적합하기는 하나 실시예 2 내지 4와 비교하여 그 효과가 증진되지 못하고 있음을 알 수 있으며, 이에 규산칼슘(CaSiO3)계의 첨가량이 적절한 범위에서 첨가되는 것이 바람직함을 알 수 있다.However, in the case of Example 5, although it is suitable for both non-combustibility and gas hazard test, it can be seen that the effect is not enhanced compared to Examples 2 to 4, and the addition amount of calcium silicate (CaSiO 3 ) system is appropriate It can be seen that it is preferable to add in the range.
