Description
본 발명은 고열과 화재 발생시에 전력설비의 케이블이 소실되어 합선 또는 단전으로 인한 재난사고에 대응하며 전력 케이블의 기능을 유지하는 실리콘고무 조성물의 제조방법에 관한 것으로, 상기 케이블을 제조할 때 작업공정을 단순화하여 생산비용을 절감하고 재료의 부실을 막을 수 있는 내화 성능이 우수한 실리콘 난연 내화 케이블의 제조방법에 관한 것이다. The present invention relates to a method for producing a silicone rubber composition to cope with a disaster caused by a short circuit or power failure due to the loss of the cable of the power equipment during high heat and fire, and to maintain the function of the power cable. The present invention relates to a method for manufacturing a silicone flame-retardant fire-resistant cable having excellent fire resistance, which can simplify production costs, reduce production costs, and prevent material loss.
일반적으로 절연재는 광도선과 전기도선 또는 광케이블이나 전기케이블용의 피복을 위해서나 또는 상기 도선이나 케이블에서 케이블 심선의 절연을 위해 사용된다. 상기 도선은 예컨대 전력선이나 정보 전달 또는 데이터 통신에 쓰이는 도선이며, 상기 도선의 절연을 위해 사용되는 피복재로는 PVC, PE 등이 있다. Insulation materials are generally used for the sheathing of optical conductors and electrical conductors or optical cables or electrical cables, or for the insulation of cable cores in said conductors or cables. The conductive wires are, for example, power wires, conductive wires used for information transmission or data communication, and coating materials used to insulate the conductive wires include PVC and PE.
화재 발생 시 특수 절연재에 의해 일정기간 동안 도선의 기능유지가 보장되어야 한다. 이 기간 동안 기계, 장치, 기구에는 전기가 공급되어야 하고, 정보를 전달할 수 있어야 한다. 상기 기간은 건물 안에 있는 모든 사람들이 연락을 받고 건물을 벗어나거나 경우에 따라서는 물건들을 안전한 곳에 가져다 둘 수 있을 때까 지 건물의 조명이 켜져 있는 기간으로 정해져야 한다.In the event of fire, special insulation should ensure that the conductors remain functional for a certain period of time. During this time, the machinery, apparatus and equipment must be supplied with electricity and capable of transmitting information. The period shall be defined as the period of time the building is illuminated until all persons in the building are informed and able to leave the building or, in some cases, to keep the goods in a safe place.
그러나, 현재 공지된 난연성 케이블을 제조하는 공정은 매우 복잡하고 또한 첨가되는 재료의 다양성과 복잡한 공정으로 비용이 많이 소요되는 단점이 있었다. 또한 고열 또는 화재시에 일정시간 단전되지 아니하고 유지되는 기능이 미비하여 실제적으로 현장에 적용하기에 부적합하거나 어려움이 따랐다. 그러므로 상기한 기능유지가 보장되며 부실 되는 재료를 줄여 단순한 작업공정과 비용 절감이 절실히 요구되고 있는 실정이다.However, currently known processes for producing flame retardant cables are very complicated and costly due to the variety of materials added and complicated processes. In addition, there was a lack of function to be maintained without being cut off for a certain period of time in high heat or fire, which was not suitable or practically difficult to apply to the site. Therefore, the above-described functional maintenance is guaranteed, and a simple work process and cost reduction are urgently required by reducing ineffective materials.
본 발명은 상기와 같은 문제점을 해소하기 위해 안출 된 것으로서, 그 목적은 화재시에 일정기간 동안 도선의 기능유지가 보장되어야 하며, 공정을 단순화하여 생산비용을 절감하고, 재료의 부실을 막을 수 있으면서도 난연 내화 기능이 우수한 실리콘 난연 내화 케이블의 제조방법을 제공하고자 한다. The present invention has been made to solve the above problems, the purpose of which should be to maintain the function of the conductor for a certain period of time in the event of fire, and simplify the process to reduce the production cost, while preventing the loss of materials An object of the present invention is to provide a method for manufacturing a silicone flame retardant fire resistant cable having excellent flame retardant fire resistance.
본 발명은 상기와 같은 목적을 달성하기 위한 실리콘 난연 내화 케이블의 제조방법을 제공함에 있어서, 산화마그네슘, 산화알루미늄, 틴옥사이드, 산화칼슘 및 산화바륨으로 이루어진 그룹에서 선택한 금속산화물과 가열시에 산화물을 생성하는 이 그룹의 금속화합물, 붕산 또는 붕산아연을 최소 하나의 불포화기를 가진 백금 복합체를 준비한 후 실리콘고무와 가소제로서 폴리디메틸실록산과 열안정제인 철옥토에이트와 보강제를 투입한 후 교반기를 통하여 혼합하여 제조한 1차 밀링(Milling)공정과; 상기 1차 밀링공정을 통과한 조성물을 압출기에 넣어서 굵기 5.5㎜의 전선에 피복 0.7㎜의 두께로 압출하는 2차 압출공정과; 상기 압출기를 통과한 조성물을 히터박스가 장착되어 온도가 450℃ 내지 500℃로 유지되는 경화라인을 통과하는 3차 경화공정;을 통해 실리콘 난연 내화 케이블을 제조하고자 한다.The present invention provides a method for producing a silicon flame-retardant fire-resistant cable for achieving the above object, the oxide when heated with a metal oxide selected from the group consisting of magnesium oxide, aluminum oxide, tin oxide, calcium oxide and barium oxide.
