Description

방화직포용 수지조성물Resin Composition for Fireproof Fabric

본 발명은 방화직포용 수지조성물에 관한 것으로서, 더욱 상세하게는 디펜타에리쓰리톨 등을 혼합한 발포성 무기재료 혼합물에 수용성 수지를 혼합하고 여기에 액상 난연제를 첨가하여 통신 및 전력 케이블 수선시 제거하기 쉽고 재사용이 가능하며 내수성 및 방화특성이 우수한 통신 및 전력 케이블 보호용 방화직포로 유용한 수지조성물에 관한 것이다.The present invention relates to a resin composition for fire-retardant fabrics, and more particularly, to mix a water-soluble resin in a foamable inorganic material mixture in which dipentaerythritol and the like are mixed, and to add a liquid flame retardant thereto to remove the cable during repair of communication and power cables. The present invention relates to a resin composition useful as a fireproof fabric for communication and power cable protection that is easy and reusable and has excellent water resistance and fire resistance.

최근 급격한 산업의 발달과 통신 서비스의 증가로 인하여 통신망과 전력망이 발달하고 있고, 이에따라 과다한 배선과 뇌우 등 천재로 인한 화재가 빈번하고 있는데, 화재 발생시에는 장시간의 통신두절 또는 단전 등으로 산업체는 물론 가정에서도 작업성이 저하되고 경제적 손실을 입게된다.Recently, due to the rapid development of the industry and the increase of communication services, communication networks and electric power grids have been developed, and accordingly, fires due to genius such as excessive wiring and thunderstorms are frequently occurring. Workability is also lowered and economic losses occur.

따라서, 통신시설과 전력망을 화재로부터 보호하기 위한 노력이 필요한데 지금까지는 통신 케이블의 표면에 방화도료를 도포하는 방법을 채택해 왔다. 이 방법은 케이블을 시설한 후에 도포하기 때문에 도료를 칠하는데 많은 시간과 인력이 소모될 뿐 아니라 케이블 보수시 약간의 움직임에 의해서도 도포면이 박리되거나 균열이 발생하는 문제가 있다. 또한, 도료는 도포 후 완전히 건조시켜야 도막이 단단히 케이블에 접착되고, 도막성질도 향상되며 수분과 수용화 중화제가 완전히 제거되어 내수성이 올라가게 된다. 그러나, 상기와 같이 통신구 내의 환경에서 시공하면 충분한 건조가 이루어지기 위해서는 오랜 시간이 소요되며, 일부 침수구간의 경우 시공 후 건조되기 전에 물방울이 떨어져 도막이 훼손되는 경우가 발생하는 문제가 있다. 또한 케이블의 표면에 도료가 직접 도포되기 때문에 열전달 정도가 높아 화재 발생시 열차단에도 한계가 있다. 그리고 통신구 천정으로부터 떨어지는 물 등에 의하여 도포된 도료가 시간이 지남에 따라 벗겨져 나가는등 내수성에도 문제가 많았다. 이에 따라 방수가 완벽하지 않은 곳에서는 주기적으로 다시 도장작업을 실시해야 하므로 유지보수에 비용이 많이 드는 문제가 있다.Therefore, efforts are needed to protect communication facilities and power grids from fire. Until now, a method of applying a fire retardant coating on the surface of a communication cable has been adopted. This method does not only consume a lot of time and manpower to paint because it is applied after the installation of the cable, there is a problem that the coating surface is peeled off or cracks due to slight movement during cable repair. In addition, the paint must be completely dried after application, the coating film is firmly adhered to the cable, the film properties are also improved, the water and the water-soluble neutralizing agent is completely removed, the water resistance is increased. However, if the construction in the environment within the communication zone as described above takes a long time to achieve a sufficient drying, there is a problem that some of the submerged section is damaged by the drop of water drops before drying after construction. In addition, since the paint is directly applied to the surface of the cable, the heat transfer degree is high, there is a limit to the thermal cutoff in the event of fire. In addition, the paint applied by water falling from the ceiling of the communication port, such as peeling off over time, there were many problems in water resistance. Accordingly, where the waterproof is not perfect, it is necessary to perform the painting work again periodically, which causes a problem of costly maintenance.

따라서 현재에는 케이블 등의 방화가 요구되는 부위에 직접 도료를 도포하기보다는 방화용 수지조성물을 제조하고 이를 유리섬유 직물 등에 도포시켜 만든 방화직포를 방화가 요구되는 부위에 피복하는 방법을 선택하고 있다. 일반적으로 방화용 수지조성물로는 방화성능이 우수한 무기계 방화재료를 사용하는 바, 무기계 방화재료는 내수성이 약하여 지하실의 습기나 천정으로부터 떨어지는 물방울에 의하여 장기간 유지시 벗겨지고, 또한 딱딱하기 때문에 굴곡성이 나빠 굽힐 경우에는 방화재가 갈라지고 심하면 탈리하는 문제가 있다. 또한 내수성과 굴곡성을 향상시키기 위해서 무기계 방화재료에 비닐아세테이트 수지 또는 클로로프렌과 같은 유기물 수지를 첨가하기도 하지만, 이러한 경우 방화특성이 저하되는 문제가 있다.Therefore, rather than applying paint directly to the areas where fire protection is required, such as cables, a method of manufacturing a fire protection resin composition and coating the fire protection fabric made by applying the same to glass fiber fabrics is selecting a method of fire protection. In general, as the resin composition for fire protection, an inorganic fire protection material having excellent fire protection performance is used. The inorganic fire protection material is poor in water resistance due to its poor water resistance and is peeled off for a long time by water droplets falling from the basement moisture or the ceiling. When bent, there is a problem in that the fire is cracked and severely detached. In addition, in order to improve water resistance and bendability, an organic resin such as vinyl acetate resin or chloroprene is added to the inorganic fire protection material.

본 발명의 발명자들은 상기 무기계 방화 도포재료의 문제점을 해결하기 위해 발포성 무기재료에 내수성과 유연성이 우수한 수지를 혼합하고 또한 이로인한 방화성 저하를 막기 위하여 브롬계 난연제를 첨가한 수지조성물을 사용한 방화직포를 이미 특허출원한 바 있다[대한민국특허출원 제95-6207호].In order to solve the problems of the inorganic fire-retardant coating material, the inventors of the present invention mix a resin having excellent water resistance and flexibility with a foamable inorganic material and use a resin composition containing a bromine-based flame retardant to prevent the lowering of fire resistance. It has already applied for a patent [Korean Patent Application No. 95-6207].

그러나 본 발명자들은 상기 방화직포에 만족하지 않고 보다 내수성이 향상된 방화직포용 수지조성물을 제조하기 위해 연구노력한 결과, 암모니움 폴리포스페이트 등의 발포성 무기재료 혼합물, 수용성 수지 혼합물 및 계면활성제로 이루어진 방화직포용 수지조성물에 염화파라핀계 액상난연제를 함유시킴으로써 파라핀, 왁스, 알파올레핀에 의해 내수성이 향상되었고 또한 액상 난연제와 수용성 수지의 분산력 향상으로 인하여 제조된 수지조성물이 유리섬유 직물등의 기재에 대한 접착력이 증진되어 굴곡성 및 난연성이 크게 향상된 방화직포용 수지조성물을 제조함으로써 본 발명을 완성하였다.However, the present inventors have been unsatisfied with the fireproof woven fabric and have tried to prepare a resin composition for fireproof woven fabric having improved water resistance. As a result, the fireproof woven fabric made of a foamable inorganic material mixture such as ammonia polyphosphate, a water-soluble resin mixture, and a surfactant By containing paraffinic chloride flame retardant in the resin composition, the water resistance is improved by paraffin, wax, and alpha olefin, and the resin composition produced by improving the dispersibility of the liquid flame retardant and water-soluble resin improves the adhesion to the substrate such as glass fiber fabric. The present invention was completed by producing a resin composition for fire-retardant fabrics having greatly improved flexibility and flame retardancy.

따라서 본 발명은 우수한 굴곡성과 내수성을 가지면서 동시에 우수한 방화특성을 갖는 방화직포용 수지조성물을 제공하는데 그 목적이 있다.Accordingly, an object of the present invention is to provide a resin composition for fire-retardant fabric having excellent flexibility and water resistance and at the same time having excellent fire protection properties.

Apply wealth. At this time, if the coating amount of the resin composition is less than 50 parts by weight, the foamability is insufficient, the flame retardant effect is insufficient, and if it exceeds 400 parts by weight, cracks may occur during bending, insufficient moisture drying, or defects such as bubbles due to overheating during drying. There is. And glass fiber fabrics with weight per area of 100 to 1000 g / ㎡ is used. If the weight per area is less than 100 g / m 2, the heat barrier property is lowered.

이와 같은 과정을 통하여 제조된 방화직포를 통신 케이블이나 전력선에 피복하면 케이블의 방화처리가 완료되는데, 이때 보다 우수한 방화성을 갖게하기 위해서 케이블과 방화직포 사이에 수지폼 또는 자기소화성이 우수한 플라스틱 판재와 같은 난연성 충전제를 충전할 수도 있다.Fire protection of the cable is completed when the fireproof fabric manufactured through the above process is coated on the communication cable or the power line. In this case, the resin foam or the plastic board having excellent self-extinguishing property is provided between the cable and the fireproof fabric in order to have better fire resistance. Flame retardant fillers may also be filled.

The resin composition has excellent handling properties, such as excellent flexibility, wrapping cable, and easy sewing. When the fireproof fabric is manufactured using the resin composition, the paint is completely dried, and thus the water and the water soluble neutralizing agent are completely removed. In the event of a fire, the foaming inorganic material in the resin composition is foamed to protect the cable from flame, and the toxic gas generated when the resin is carbonized is significantly reduced.

따라서 본 발명의 수지조성물은 통신 케이블이나 전력선의 방화재료로 유용한 방화직포 제조에 매우 유용하다.Therefore, the resin composition of the present invention is very useful for producing fireproof woven fabrics useful as fire protection materials for communication cables and power lines.

상기 실시예 1 ∼ 3 및 비교예 1 ∼ 2 에서 얻은 각각의 방화직포(가로 5cm × 세로 5cm)를 3% 식염수에 넣어 40 ℃로 유지한 후 10일간 침적을 하여 내염수성을 측정하였다. 그 결과 본 발명에 따른 실시예 1 ∼ 3에 의해 제조된 방화직포는 갈라짐 또는 부풀어 오름이 전혀 없어 내염수성이 아주 양호한 것으로 관찰되었으나, 비교예 1 ∼ 2에 의해 제조된 방화직포는 1일 침적후에 방화직포의 표면이 갈라짐과 부풀어 오름이 관측되었으며 10일 경과한 후에는 방화직포의 전체 표면에 갈라짐과 부풀어 오름이 심하게 나타나는 것으로 보아 내염수성이 매우 낮음을 알 수 있다.Each fireproof fabric (5 cm x 5 cm) obtained in Examples 1 to 3 and Comparative Examples 1 to 2 was put in 3% saline solution and kept at 40 ° C, followed by immersion for 10 days to measure saline resistance. As a result, the fireproof fabrics prepared in Examples 1 to 3 according to the present invention had no cracking or swelling, and thus the saline resistance was observed to be very good. However, the fireproof fabrics prepared according to Comparative Examples 1 to 2 were observed after 1 day deposition. The cracking and swelling of the surface of the fireproof fabric were observed, and after 10 days, the cracking and swelling appeared severely on the entire surface of the fireproof fabric, indicating that the salt water resistance was very low.

그리고 각각의 방화직포 1 m를 3600 본의 통신용 케이블에 감은 다음 부탄가스 토오치로 1분간 직접 표면에 접촉시켰다. 이때 불꽃의 길이는 약 60 mm로 하고 토오치의 입구에서 시험편까지의 거리는 40 mm 정도로 유지하였다. 이와 같이 불꽃 분산시험을 한 다음 방화직포를 제거하고 케이블의 표면상태를 관찰한 결과, 본 발명에 따른 실시예 1 ∼ 3에 의해 제조된 방화직포는 케이블의 외피에 방화도료가 약간 묻어나고 표면은 열에 의하여 부들부들해 졌으나 직접적인 손상은 없었으며,케이블의 심선은 전혀 손상되지 않았다. 그러나 비교예 1에 의해 제조된 방화직포는 발포면적이 전혀 나타나지 않았고 비교예 2에 의해 제조된 방화직포는 약간의 발포현상이 관측되었으며, 방화직포를 제거하고 케이블의 표면 상태를 관측한 결과 실시예 1 ∼ 3에 비교하여 케블 외피에 방화도료가 많이 묻어나고 열전달이 잘되어 케이블 표면은 많이 부들부들해졌고 직접적인 손상은 없었으며, 케이블 심선은 전혀 손상되지 않았다.1 m of each fireproof fabric was wound around 3600 communication cables, and then directly contacted with a butane gas torch for 1 minute. At this time, the length of the flame was about 60 mm and the distance from the entrance of the torch to the test piece was maintained at about 40 mm. As a result of the flame dispersion test, the fireproof fabric was removed and the surface condition of the cable was observed. As a result, the fireproof fabric prepared in Examples 1 to 3 according to the present invention had a slight amount of fireproof paint on the outer skin of the cable. It was swollen by heat, but there was no direct damage, and the cable cores were not damaged at all. However, the fireproof fabric produced by Comparative Example 1 did not show any foam area, and the fireproof fabric prepared by Comparative Example 2 had a slight foaming phenomenon. As a result of removing the fireproof fabric and observing the surface state of the cable, Compared with 1 ~ 3, Kble's sheath had a lot of fire retardant paint and heat transfer, so the cable surface was softened, there was no direct damage, and the cable core was not damaged at all.

그밖에 팽창특성, 방염성 및 굴곡성에 대하여 다음과 같은 방법으로 측정하였으며, 그 결과는 다음 표 2에 나타낸 바와 같다.In addition, the expansion properties, flame retardancy and flexibility were measured by the following method, and the results are shown in Table 2 below.

팽창특성 : 열풍기에서 300 ℃, 30분 방치Expansion characteristics: Leave at 300 ℃ for 30 minutes in a hot air fan

방염성 : 연소실에서 850 ∼ 900 ℃, 20분 연소Flame retardant: Combustion chamber at 850∼900 ℃ for 20 minutes

굴곡성 : 케이블 외경의 20배 원통에 시편을 감아 구부림 2회Flexibility: Bending twice by wrapping the specimen in a cylinder 20 times the outer diameter of the cable
