Description

경사면에 균일한 두께로 시공할 수 있는 우레탄 바닥재 조성물 및 그 시공방법{An urethane composite for footway bottom and execution method by the composite}Urethane flooring composition and construction method that can be applied to slopes with uniform thickness {An urethane composite for footway bottom and execution method by the composite}

본 발명은 잘 흘러내리지 않아서 경사진 바닥면에 시공할 때도 균일한 두께로 시공할 수 있는 우레탄 바닥재 조성물에 관한 것으로, 저렴한 비용으로 시공할 수 있고, 시공 후에 표면이 미끄럽지 않고, 외관이 수려하며, 방수 기능이 있고, 탄성과 신장률이 좋아서 시공된 곳에서 보행할 때 보행감이 우수한 바닥재에 관한 것이다.       The present invention relates to a urethane flooring composition that can be applied with a uniform thickness even when applied to a slanted bottom surface because it does not flow well, and can be installed at low cost, the surface is not slippery after construction, and the appearance is beautiful, It is waterproof and has good elasticity and elongation, so it is related to the flooring with excellent walking comfort when walking in the construction place.

통상 도로의 보도면은 콘크리트나 아스콘으로 포장되어 있으나 충격에 약하여 쉽게 마모되거나 부서져서 자주 재시공해야 하기 때문에 경제적 손실이 크고, 탄성이 없어 보행감이 좋지 않고, 다양한 디자인의 연출이 불가능한 문제점이 있다.      Usually, the sidewalk surface of the road is paved with concrete or ascon, but it is weak to impact, so it is easily worn or broken, so it needs to be rebuilt frequently, resulting in a large economic loss, lack of elasticity, poor walking feeling, and inability to produce various designs.

또한, 내구성이 우수하고 외관이 수려하도록 하기 위하여 대리석을 사용하여 바닥을 시공할 경우에는 바닥면이 미끄럽고, 바닥재 자체의 가격이 비싸 고액의 비용이 소요되고, 바닥재 사이에 이음새가 있어 때가 잘 묻게 되고, 들뜸 현상과 균 열이 발생하는 문제점이 있다.     In addition, when the floor is constructed using marble for excellent durability and beautiful appearance, the floor surface is slippery, the cost of the flooring itself is expensive, high cost is required, and there are seams between the floorings, which makes it easy to get a good time. There is a problem of lifting and cracking.

또한, 고무칩을 이용하여 바닥면을 시공할 경우는 탄성에 의한 보행감은 우수하나, 방수기능이 없어 물이 침투되어 하부층을 부식시키고, 충격에 약하여 쉽게 마모되거나 부서지기 때문에 자주 보수하거나 재시공해야 하는 문제점이 있다.     In addition, when the floor surface is constructed using rubber chips, the walking feeling by elasticity is excellent, but there is no waterproof function, so water penetrates and corrodes the lower layer, and it is weak and easily worn or broken due to the impact. There is a problem.

최근에는 탄성과 내구성이 우수하여 저렴한 가격으로 시공할 수 있도록 폴리우레탄을 주재로 한 바닥재가 제공되고 있으나, 시중에 제공되고 있는 폴리우레탄 바닥재의 경우 자체 흐름성이 있어 경사진 바닥면에 시공할 경우 자중에 의하여 바닥재가 낮은 쪽으로 흘러 내려 균일한 두께로 시공하기가 어려운 문제점이 있다.      Recently, polyurethane flooring has been provided so that it can be installed at a low price due to its excellent elasticity and durability. However, the polyurethane flooring material provided on the market has its own flowability, so when installing it on a sloped floor Due to its own weight, the flooring material flows down to the lower side, making it difficult to construct a uniform thickness.

따라서 경사면에 시공할 경우 균일한 두께로 시공되지 않고 시공하고자 하는 바닥면의 낮은 쪽과 높은 쪽에 두께가 다르게 시공됨으로써 상대적으로 얇게 시공된 높은 쪽은 두껍게 시공된 낮은 쪽에 비해 보행감이 좋지 않고, 수명도 훨씬 짧아지게 된다.      Therefore, when it is installed on the inclined surface, it is not constructed with a uniform thickness, but the thickness is applied differently on the lower side and the higher side of the floor to be installed, so the relatively thinner high side is less comfortable to walk than the thicker side, and the life is not good. Will also be much shorter.

또한 이러한 바닥재는 비가 와서 표면에 물기가 있을 경우 미끄러워서 보행할 때 위험하고, 경사면에 시공할 경우에는 바닥재가 낮은 쪽으로 흘러내려 무늬를 형성하기가 어렵기 때문에 바닥면이 수려한 외관을 갖도록 시공하기도 어렵다.      In addition, such flooring is dangerous when it is rainy and slippery when there is water on the surface, and when it is installed on an inclined surface, it is difficult to construct the floor surface to have a beautiful appearance because it is difficult to form a pattern by flowing the flooring material to a lower side. .

따라서 본 발명은 프라이머층의 표면에 흐름성이 없는 상태로 경화되는 제1우레탄 바닥재를 도포하여 바탕층을 형성하고, 상기 바탕층의 표면으로 발포성을 갖는 제2우레탄 바닥재를 무늬형성시트를 사용하여 엠보싱무늬층이 형성되도록 하여 경사면에서도 일정 두께로 바닥재를 시공할 수 있도록 하고, 엠보싱에 의하여 미끄럼을 방지하고, 무늬를 형성함으로써 수려한 외관을 얻을 수 있도록 하였다.      Therefore, the present invention is applied to the surface of the primer layer to form a base layer by coating the first urethane flooring cured in a non-flowable state, the second urethane flooring material having a foamability to the surface of the base layer using a patterning sheet The embossed pattern layer was formed so that the flooring material could be constructed at a predetermined thickness even on the inclined surface, and slipping was prevented by embossing, thereby forming a beautiful appearance.

이를 위하여 본 발명의 바닥재 조성물은 포리올(POLYOL)과 폴리이소시아네이트(POLYISOCYANATE)를 중합 반응시킨 우레탄 수지를 주제로 하고, 포리올에 가교제, 충전제, 가소제, 경화촉진제, 소포제, 내후성 향상제, 탈수제, 착색제, 안정제를 혼합시킨 칼라 우레탄 수지를 경화제로 하여 1:3.5(WT)의 비율로 혼합시켜 흐름성이 없는 상태로 경화되는 제1우레탄 바닥재와,     To this end, the flooring composition of the present invention is based on a urethane resin polymerized with polyol (POLYOL) and polyisocyanate (POLYISOCYANATE). A first urethane flooring material which is cured in a state in which there is no flowability by mixing a color urethane resin mixed with a curing agent at a ratio of 1: 3.5 (WT),

포리올과 폴리이소시아네이트를 중합 반응시킨 우레탄 수지를 주제로 하고, 포리올에 발포제, 가교제, 충전제, 가소제, 경화촉진제, 소포제, 내후성 향상제, 탈수제, 착색제, 안정제를 혼합시킨 칼라 발포 우레탄 수지를 경화제로 하여 1:1(WT)로 혼합시킨 상태에서 골재를 20%(WT)를 혼합시킨 제2우레탄 바닥재를 제공하도록 한 것이다.Based on the urethane resin polymerized by polyol and polyisocyanate, a color foamed urethane resin obtained by mixing a polyol with a blowing agent, a crosslinking agent, a filler, a plasticizer, a curing accelerator, an antifoaming agent, a weather resistance improving agent, a dehydrating agent, a coloring agent, and a stabilizer is used as a curing agent. It is to provide a second urethane flooring material in which 20% (WT) is mixed with aggregate in a state of mixing into 1 (WT).

상기 조성물로 이루어진 바닥재를 사용하여 바닥을 시공할 경우에는 경사진 바닥면을 시공할 때에도 균일한 두께로 시공할 수 있도록 하여 전체적으로 보행감이 우수하고, 내구성이 우수하여 보수 및 재시공에 의한 비용을 대폭 절감할 수 있음은 물론, 비가 와서 시공된 바닥면의 표면에 물기가 있을 경우에도 잘 미끄러지지 아니하여 보행시의 위험을 방지할 수 있고, 다양한 무늬의 형성이 가능하여 저렴한 비용으로 수려한 외관을 제공할 수 있게 되는 것이다.In the case of constructing the floor using the flooring made of the composition, the construction can be constructed with a uniform thickness even when the inclined floor surface is constructed, so that the overall walking feeling is excellent, and the durability is excellent, thereby greatly reducing the cost of repair and reconstruction. Not only can it reduce, but it does not slip well even when there is water on the surface of the floor where it rains, preventing the risk of walking, and it is possible to form various patterns to provide a beautiful appearance at low cost. It will be possible.

본 발명은 콘크리트, 아스콘 등으로 포장된 바닥층(1)의 표면에 프라이머층(2)을 형성하고, 상기 프라이머층(2)의 표면에는 포리올과 폴리이소시아네이트를 중합 반응시킨 우레탄 수지를 주제로 하고, 포리올에 가교제, 충전제, 가소제, 경화촉진제, 소포제, 내후성 향상제, 탈수제, 착색제, 안정제 등의 첨가제를 혼합시킨 칼라 우레탄 수지를 경화제로 하여 1:3.5(WT)의 비율로 혼합시켜 흐름성이 거의 없는 상태로 경화되는 제1우레탄 바닥재를 도포시켜 바탕층(3)을 형성하고, 상기 바탕층(3)의 표면에는 포리올과 폴리이소시아네이트를 중합 반응시킨 우레탄 수지를 주제로 하고, 포리올에 발포제, 가교제, 충전제, 가소제, 경화촉진제, 소포제, 내후성 향상제, 탈수제, 착색제, 안정제를 혼합시킨 칼라 발포 우레탄 수지를 경화제로 하여 1:1(WT)로 혼합시킨 상태에서 골재를 20 ~30%(WT)를 혼합시킨 제2우레탄 바닥재를 무늬형성시트(6)를 사용하여 엠보싱무늬층(4)을 형성하고, 상기 엠보싱무늬층(4)의 표면으로는 코팅층(5)을 형성하여 바닥재를 시공하는 것이다.     The present invention is based on the urethane resin to form a primer layer (2) on the surface of the bottom layer (1) packaged with concrete, ascon, etc., the polymerization reaction of polyol and polyisocyanate on the surface of the primer layer (2), Polyurethane resin, in which polyurethane is mixed with additives such as a crosslinking agent, a filler, a plasticizer, a curing accelerator, an antifoaming agent, a weathering enhancer, a dehydrating agent, a coloring agent, and a stabilizing agent, is mixed with a curing agent at a ratio of 1: 3.5 (WT) to have almost no flowability. The base layer 3 is formed by applying the first urethane flooring material to be cured in a state, and the surface of the base layer 3 is made of a urethane resin polymerized with polyol and polyisocyanate, and the foaming agent, the crosslinking agent, A phase in which 1: 1 (WT) is mixed with a color foamed urethane resin in which a filler, a plasticizer, a curing accelerator, an antifoaming agent, a weather resistance improving agent, a dehydrating agent, a colorant, and a stabilizer is mixed. The second urethane flooring material in which the aggregate was mixed 20-30% (WT) in the form of the embossed pattern layer 4 was formed using the pattern forming sheet 6, and the coating layer was formed on the surface of the embossed pattern layer 4. (5) to form the flooring.

상기 바닥층(1)은 지형에 따라 적정한 구배를 갖도록 해야 하고, 특히 표면의 평활성은 3mm 이내가 되도록 하고, 신설 포장된 콘크리트는 20℃에서 최소 3주 이 상, 아스콘은 최소 2주 이상 양생시켜야 하고, 아스콘의 밀도는 94% 이상, 콘크리트는 표면의 강도가 180Kg/㎡ 이상이어야 한다.     The bottom layer (1) should have a proper gradient according to the terrain, in particular to ensure the smoothness of the surface within 3mm, newly paved concrete should be cured at least 3 weeks at 20 ℃, ascon at least 2 weeks , Ascon density should be more than 94% and concrete should have more than 180Kg / ㎡ surface strength.

바닥층(1)이 충분히 건조되지 않으면 접착이 나빠 박리되거나 수분의 기화에에 의해 부풀어 오르는 현상이 있으며, 특히 도막 형성에 지장을 주므로 함수율이 8% 이내일 때 시공한다.     If the bottom layer 1 is not sufficiently dried, the adhesion is poor and there is a phenomenon of swelling due to evaporation of moisture, and in particular, since it hinders the formation of the coating film, it is applied when the water content is within 8%.

이후, 시공된 바닥층(1)의 표면은 통상의 방식대로 하지정리를 한다.      Thereafter, the surface of the constructed bottom layer 1 is cleaned up in the usual manner.

상기 프라이머층(2)은 하지에 대한 접착성과 내수성을 좋게 하기 위하여 형성하는 것으로서, 바닥층(1)의 표면 강도를 보강하고 하지로부터 수분이 침투하는 것을 방지하는 효과가 있도록 하는 것으로, 바닥재를 시공할 때 사용되는 통상의 프라이머액을 바닥층(1)의 표면에 스프레이나 롤러를 사용하여 0.2 ~ 0.5Kg/㎡ 도포하고, 도포가 완료된 후 1시간 정도 경과한 후 다음 공정에 들어간다.     The primer layer (2) is formed to improve the adhesion and water resistance to the bottom, to reinforce the surface strength of the bottom layer (1) and to prevent the penetration of moisture from the bottom, the flooring can be constructed The usual primer solution used at the time is applied to the surface of the bottom layer (1) using a spray or a roller 0.2 ~ 0.5Kg / ㎡, and after about 1 hour after the application is completed, and enters the next step.

바탕층(3)은 시공 현장에서 밑이 둥근 혼합용기에 제1우레탄 바닥재의 주제를 먼저 붓고 경화제를 부어 기포가 혼입되지 않게 주의하면서 전용용제(톨류엔)를 5% 이내 희석하여 3~5분 고속 믹서로 1000rpm으로 혼합한 후, 상기 프라이머층(2)의 표면에 전용 엠보싱기계를 사용하여 2mm 정도 두께가 되도록 고르게 살포한 후, 20℃에서 24시간 이상 양생하여 형성한다.      The base layer (3) is poured by pouring the main material of the first urethane flooring material into a round bottom mixing container at the construction site first, and then pouring a hardener to prevent mixing of air bubbles, while diluting the exclusive solvent (toluene) within 5% for 3 to 5 minutes. After mixing at 1000 rpm with a high speed mixer, the surface of the primer layer 2 is evenly sprayed to a thickness of about 2 mm using a dedicated embossing machine, and then cured at 20 ° C. for 24 hours or more to form.

바탕층(3)에 사용되는 제1우레탄 바닥재는 포리올과 폴리이소시아네이트를 80℃에서 3시간 반응시켜 부가 중합에 의하여 주제가 얻어지고, 경화제는 포리올에 가교제, 충전제, 가소제, 경화촉진제, 소포제, 내후성 향상제, 탈수제, 착색제, 안정제 등의 첨가제를 혼합시켜 얻는 것으로, 이렇게 하여 얻어진 주제는 25℃에서 점도 6,000±1,000cps의 담황색 액상 우레탄 수지가 되는데, 경화제는 첨가된 착색제의 색체를 띠면서 밀가루 반죽과 같이 흐름성이 거의 없는 반고체 상태의 우레탄 수지로서, 각각 포장되어 제공되는 것을 시공현장에서 1:3.5(WT)의 비율로 혼합하여 사용한다.     The first urethane flooring material used in the base layer 3 is obtained by subjecting polyol and polyisocyanate to react for 3 hours at 80 ° C. by addition polymerization, and the curing agent is a crosslinking agent, filler, plasticizer, curing accelerator, antifoaming agent, and weathering enhancer in the polyol. It is obtained by mixing additives such as dehydrating agent, colorant, stabilizer, etc. The obtained material is a pale yellow liquid urethane resin having a viscosity of 6,000 ± 1,000 cps at 25 ° C. Semi-solid urethane resin with almost no flowability, which is packaged and provided, is used by mixing at a ratio of 1: 3.5 (WT) at the construction site.

이때 주제에 대한 경화제의 혼합비율이 3.5배 이하이면 흐름성이 남아 있어 경사면에서 균일하기 도포하기가 어렵고, 3.5배 이상이면 너무 경화되어 도포 작업 자체가 어렵다.At this time, when the mixing ratio of the curing agent to the subject matter is 3.5 times or less, the flowability remains, and it is difficult to apply uniformly on the inclined surface.

위와 같은 혼합비율에 의하여 얻어지는 제1우레탄 바닥재는 25℃에서 20~60분의 가사시간, 60±5(shore "A")의 경도, 25Kgf/㎠ 이상의 인장강도, 15 Kgf/cm 이상의 인열강도, 450% 이상의 신율로 이루어지는 물성을 갖게 된다.The first urethane flooring material obtained by the above mixing ratio is 20 ~ 60 minutes pot life at 25 ℃, hardness of 60 ± 5 (shore "A"), tensile strength of 25Kgf / ㎠ or more, tear strength of 15 Kgf / cm or more It has physical properties of elongation of 450% or more.

엠보싱무늬층(4)은 상기 바탕층(3)의 표면에 무늬형성시트(6)를 깔고, 무늬형성시트(6)의 통공된 부분으로 시공 현장에서 조제한 제2우레탄 바닥재를 전용 엠보싱기계를 사용하여 1mm 정도의 두께가 되도록 고르게 살포하여 어느 정도 굳어진 후 무늬형성시트(6)를 제거하는 방법으로 형성한다.     The embossed pattern layer 4 is a patterned sheet 6 is laid on the surface of the base layer 3, and the second urethane flooring material prepared at the construction site as a perforated part of the pattern forming sheet 6 is used for the embossing machine. After spraying evenly so as to have a thickness of about 1mm is formed by a method of removing the pattern forming sheet (6) to a certain extent.

엠보싱무늬층(4)에 사용되는 제2우레탄 바닥재는 시공 현장에서 밑이 둥근 혼합용기에 제2우레탄 바닥재의 주제를 먼저 붓고 경화제를 부어 기포가 혼입되지 않게 주의하면서 전용용제(톨류엔)를 5% 이내 희석하여 고속 믹서로 1000rpm으로 3~5분간 혼합한 후, 골재를 혼합하여 제조한다.     The second urethane flooring material used for the embossed pattern layer 4 is poured with a special solvent (toluene) while being careful not to mix bubbles by pouring the main material of the second urethane flooring material into the mixing vessel rounded at the construction site first and pouring a curing agent. Diluted within% and mixed for 3 to 5 minutes at 1000rpm in a high speed mixer, the aggregate is prepared by mixing.

주제는 상온(25℃)에서 3,000~4500cps의 점도를 갖는 담황색 액상의 우레탄 수지가 되고, 경화제는 첨가된 착색제의 색체를 띠면서 상온(25℃)에서 2,000~6000cps의 점도를 갖는 착색 점도 액상의 우레탄 수지가 되는 것으로, 1:1(WT)로 혼합한 상태에서 골재로서 인조규사를 20~30%(WT) 혼합하여 제조한다.     The main material is a pale yellow liquid urethane resin having a viscosity of 3,000-4500 cps at room temperature (25 ° C.), and the curing agent has a color of the added colorant and a viscosity of 2,000-6000 cps at room temperature (25 ° C.). It becomes a urethane resin, and is manufactured by mixing 20-30% (WT) of artificial silica sand as aggregate in the state mixed in 1: 1 (WT).

이때 주제에 대한 경화제의 혼합비율이 1배 이하이면 흐름성이 남아 있어서 경사면에서 균일한 두께로 도포하기가 어렵고, 1배 이상이면 지나치게 경화되어 도포 작업이 어렵다. 주제와 경화제의 혼합물에 골재를 20% 이하로 혼합하면 도포할 때 밀림 현상이 발생되고 30% 이상 혼합하면 결합력이 약해지게 된다.At this time, if the mixing ratio of the curing agent to the main material is 1 times or less, the flowability remains, making it difficult to apply a uniform thickness on the inclined surface. If the aggregate is mixed to 20% or less in the mixture of the main agent and the hardener, a crushing phenomenon occurs at the time of application, and the mixing force becomes weaker when mixed more than 30%.

위와 같은 혼합비율에 의하여 이루어지는 제2우레탄 바닥재는, 상온(25℃)에서 30~70분의 가사시간, 110±40 Kgf/㎠의 인장강도, 30±10 Kgf/cm의 인열강도, 350±100의 신율, 80±5(shore "A")의 경도로 이루어지는 물성을 갖게 된다.The second urethane flooring material made of the above mixing ratio is 30 ~ 70 minutes pot life at room temperature (25 ℃), tensile strength of 110 ± 40 Kgf / ㎠, tear strength of 30 ± 10 Kgf / cm, 350 ± It has physical properties consisting of elongation of 100 and hardness of 80 ± 5 (shore “A”).

한편, 본 발명에 사용되는 무늬형성시트(6)는 일명 아트페이퍼라는 명칭으로 규격화되어 시중에서 판매되고 있는 것을 사용하며, 무늬가 일치되도록 조합하여 깔아주고, 중간 이음부위에는 접착테이프로 부착시킨다.On the other hand, the pattern forming sheet 6 used in the present invention is standardized by the name of art paper, which is commercially available, and is used in the market, and the combination is laid to match the pattern, and attached to the middle joint with adhesive tape.

이후, 상기 바탕층(3)과 엠보싱무늬층(4)의 표면에는 표면 보호를 위한 코팅제를 스프레이 또는 롤러를 사용하여 도포하여 코팅층(5)을 형성한다.Subsequently, the surface of the base layer 3 and the embossed pattern layer 4 is coated with a spray or a roller to form a coating layer 5 to protect the surface.

상기와 같은 물성의 제1우레탄 바닥재와 제2우레탄 바닥재를 사용하여 시공하면 경사진 바닥면에 시공하는 경우에도 시공 과정에서 제1우레탄 바닥재와 제2우레탄 바닥재 모두 흐름성이 낮아서 낮은 쪽으로 흘러내리지 않아 균일한 두께로 시공할 수 있고, 제2우레탄 바닥재에 엠보싱무늬층이 형성되어 미끄럼이 방지되고, 제2우레탄 바닥재에 의하여 표면에 다양한 무늬의 연출이 가능하여 외관이 수려한 바닥 시공을 할 수 있게 된다.When the first urethane flooring material and the second urethane flooring material are used as described above, even if the construction is on the inclined floor surface, both the first urethane flooring material and the second urethane flooring material do not flow down due to low flowability during the construction process. It can be constructed with a uniform thickness, and the embossed pattern layer is formed on the second urethane flooring material to prevent slippage, and the second urethane flooring material can produce various patterns on the surface, thereby enabling beautiful flooring construction. .
