Description

정전기 방지용 테라죠 {Electrostatic Protective Terrazzo}Electrostatic Protective Terrazzo {Electrostatic Protective Terrazzo}

본 발명은 정전기 방지용 테라죠에 관한 것으로서, 더욱 상세하게는 기존의 백시멘트, 종석, 대리석 칩 등으로 구성된 테라죠 조성물에 적당량의 전도성 탄소 섬유 및 섬유 분산제를 포함하는 정전기 방지용 테라죠에 관한 것이다.The present invention relates to an antistatic terrazzo, and more particularly, to an antistatic terrazzo comprising an appropriate amount of conductive carbon fibers and a fiber dispersant in a terrazzo composition composed of conventional back cement, feldspar, marble chips and the like.

종래에는 건축물의 바닥면에 정전기를 방지할 목적으로 재료에 적절히 전기 전도성을 부여한 도전성 에폭시수지, 도전성 PVC타일, 도전성 카펫, 도전성 매트 등을 사용하여 왔다.Conventionally, conductive epoxy resins, conductive PVC tiles, conductive carpets, conductive mats and the like that have appropriately provided electrical conductivity to materials have been used for the purpose of preventing static electricity on the floor of a building.

그러나 상기 기술들은 유기질계 바인더에 금속계 물질을 분산시켜 정전기 분산 특성을 얻는 시스템으로, 정전기 분산 특성이 떨어지고, 내화성이 낮으며, 중량물의 이동시 파손 또는 변형의 우려가 있었다.However, the above techniques are systems for obtaining electrostatic dispersion characteristics by dispersing a metal-based material in an organic binder. The electrostatic dispersion characteristics are poor, fire resistance is low, and there is a fear of breakage or deformation when moving heavy materials.

본 발명의 정전기 방지용 테라죠는 무기질계로서 유기질계 바인더에 의한 기존 시스템에 비하여 전기 저항 조절이 용이하고, 내화성이 뛰어나며, 내구성이 우수하여 기존 기술의 이러한 문제점의 해결이 가능하다.The anti-static terrazzo of the present invention is an inorganic type, compared to the existing system based on the organic binder is easy to control the electrical resistance, excellent fire resistance, and excellent durability can solve these problems of the existing technology.

본 발명은 종래의 상기와 같은 문제점을 해결하기 위하여 안출된 것으로서, 정전기 분산성이 우수할 뿐만 아니라, 내구성, 내화성을 획기적으로 향상시킨 정전기 방지용 테라죠 조성물 및 그 제조방법을 제공하는데 그 목적이 있다SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and has an object of providing an antistatic terrazzo composition and a method of manufacturing the same, which not only have excellent electrostatic dispersibility but also dramatically improve durability and fire resistance.

본 발명의 상기 목적은 시멘트계 바인더, 종석류로 구성된 테라죠 조성물에 스테인레스 섬유, 섬유 분산제를 이용하므로써 달성된다.The above object of the present invention is achieved by using a stainless fiber and a fiber dispersant in a terrazzo composition composed of a cement binder and stalactites.

상기 스테인레스 섬유는 시멘트계 바인더 시스템에서 균일하게 분산되면, 섬유의 장방향으로 네트워킹이 되어 표면 저항의 조절이 매우 용이하다.When the stainless fiber is uniformly dispersed in a cement-based binder system, the stainless fiber is networked in the long direction of the fiber, so that it is very easy to control the surface resistance.

이하, 본 발명은 정전기 방지용 테라죠에 관한 것으로서 좀 더 상세하게 설명하면 다음과 같다.Hereinafter, the present invention relates to an antistatic terrazzo, which will be described in more detail as follows.

본 발명의 정전기 방지용 테라죠는 원료 조성으로 백시멘트, 종석, 대리석 칩, 1 ∼ 3 mm 길이의 스테인레스 섬유 0.10 ∼ 0.50 중량부 및 섬유분산제 0.1 ∼ 0.3 중량부를 포함하여 구성되는 것을 특징으로 하여, 표면-표면 저항 및 표면-접지 저항이 2.5 × 104Ω∼ 1.0 × 106Ω을 가지는 정전기 방지용 테라죠에 관한 것이다.The antistatic terrazzo of the present invention is characterized in that the raw material composition comprises a back cement, feldspar, marble chips, 0.10 to 0.50 parts by weight of stainless steel fibers of 1-3 mm length and 0.1 to 0.3 parts by weight of fiber dispersant, It relates to an antistatic terrazzo having a surface resistance and a surface-earth resistance of 2.5 × 10 4 kPa to 1.0 × 10 6 kPa.

상기 백시멘트, 종석, 대리석 칩은 테라죠의 주요 조성물로서, 본 발명은 이들 조성물의 조성비에 한정하지 않는다.The back cement, the keystone, and the marble chip are the main compositions of Terrajo, and the present invention is not limited to the composition ratio of these compositions.

상기의 스테인레스 섬유의 경우, 길이가 1mm ∼ 3 mm 범위로서, 그 중에서도 2mm ∼ 3mm 의 길이의 스테인레스 섬유가 가장 바람직하다.In the case of the above stainless fiber, the length is in the range of 1 mm to 3 mm, and among them, the stainless fiber having a length of 2 mm to 3 mm is most preferred.

이 때 상기 스테인레스 섬유의 길이가 3mm 를 초과하면 수지와 혼합 성능이 떨어지며, 1mm 미만이면 전기 저항 특성이 떨어진다.At this time, when the length of the stainless fiber exceeds 3mm, the mixing performance with the resin is inferior, and if it is less than 1mm, the electrical resistance property is inferior.

이 때 상기의 스테인레스 섬유의 첨가량이 0.10 ∼ 0.50 중량부로서, 바람직하게는 0.15 ∼ 0.25 가 가장 좋다. 0.10 중량부 미만 및 0.50 중량부를 초과하면 최적의 정전기 분산 성능인 2.5 × 104Ω∼ 1.0 × 106Ω를 벗어나게 된다.At this time, the addition amount of the above stainless fiber is 0.10 to 0.50 parts by weight, preferably 0.15 to 0.25 is most preferred. If it is less than 0.10 part by weight and more than 0.50 part by weight, the optimum static electricity dissipation performance is 2.5 × 10 4 4 to 1.0 × 10 6 Ω.

그러나, 상기의 스테인레스 섬유는 전기 저항을 안정적으로 조절하기 위하여서는 스테인레스 섬유의 분산성이 향상되어야 한다.However, in order to stably adjust the electrical resistance of the stainless fiber, the dispersibility of the stainless fiber should be improved.

본 발명의 상기 섬유 분산제는 스테인레스 섬유의 분산성을 개선하기 위하여 사용되었는데, 1,6 Hexandiole, Neopentylglycole 가 바람직하다.The fiber dispersant of the present invention was used to improve the dispersibility of stainless fiber, 1,6 Hexandiole, Neopentylglycole is preferred.

이 때 상기의 섬유 분산제의 첨가량이 0.1 ∼ 0.3 중량부로서, 이 범위를 벗어나면 작업성에 영향을 미치지 못하거나 경제적이지 않다.At this time, the addition amount of the fiber dispersant is 0.1 to 0.3 parts by weight, if outside this range does not affect the workability or economical.
