Description

바닥마감재용 조성물Floor Finishing Composition

제 1 도는 본 발명에 따른 바닥마감재용 조성물에 의해 시공된 바닥표면의 사진이다.1 is a photograph of the floor surface constructed by the composition for a floor finishing material according to the present invention.

본 발명은 실내 또는 복도 등의 바닥에 사용하는 바닥마감재용 조성물에 관한 것으로 특히 바닥면에 다양한 무늬와 색상을 표현하게 할 수 있음과 더불어 시공이 편리한 분무시공법을 이용할 수 있는 바닥마감재용 조성물에 관한 것이다.The present invention relates to a composition for floor finishing materials used for floors, such as indoors or hallways, and in particular, to a variety of patterns and colors can be expressed on the floor surface and to a composition for floor finishing materials that can use a convenient spray construction method will be.

일반적으로 실내나 복도 등의 바닥에는 용도를 고려하여 장식성과 실용성의 요구수준에 따라 아주 다양한 재료들이 사용되고 있는데, 이를 시공방법에 따라 구분하여 보면, 시멘트 모르타르와 같은 바름공법으로 시공하는 바닥마감재, 타일과 같은 붙임공법으로 시공하는 바닥마감재, 에폭시수지와 같은 도장공법으로 시공하는 바닥마감재 등이 있다. 이들 각각의 바닥마감재들은 시공의 편리성, 외관효과의 미려함, 실용성 및 경제성의 측면에서 볼 때 각각 일장일단이 있지만, 통상의 건물바닥에 가장 보편적으로 사용되는 것은 바름공법 및 물갈기공법으로 시공되는 인조석이라고 할 것인바, 이것은 천연 석재류에 비해 가격이 저렴하면서도 천연 석재류의 외관효과를 발휘하며, 뛰어난 내구성을 가지기 때문이다.In general, a variety of materials are used for indoor and corridor floors according to the requirements of decoration and practicality in consideration of the purpose of use, and according to the construction method, floor finishing materials and tiles, which are constructed by the coating method such as cement mortar, are used. There is a floor finishing material to be applied by the same method, such as, the floor finishing material to be applied by the coating method such as epoxy resin. Each of these floor finishing materials is finished in terms of convenience, beauty of appearance effect, practicality and economical efficiency. However, the most commonly used flooring materials are artificial stone which is applied by the painting method and the grinding method. This is because it is cheaper than natural stone, but exhibits the appearance effect of natural stone, and has excellent durability.

그러나 상기와 같은 인조석은, 대리석 등의 쇄석과 시멘트의 혼합물을 재료로 하여 이를 물에 개어서 바닥에 바르고 양생한 후 물갈기를 하는 복잡한 시공과정을 거쳐서 만들어지기 때문에, 과다한 인력투입이 요구되고, 또한 물갈기 할때 발생되는 시멘트물로 인해 주위의 벽면이 더러워지고 이를 다시 청소를 해야 하는 불편함이 있음은 물론 작업여건이 열악해져 작업자들이 기피하게 되었고, 이는 인력수급의 어려움으로 이어지고 결국은 시공비 상승을 초래하는 문제점을 야기시켰다. 또한 이와 같은 인조석은 그 무늬나 색조의 변화가 거의 제한되어 표면무늬의 다양한 표현욕구를 충족시켜 줄 수 없는 문제점이 있었다.However, the artificial stone as described above is made through a complex construction process of mixing a mixture of crushed stone such as marble and cement with water, applying it to the floor, curing it, and then grinding it. Cement water generated during the watering causes the surrounding walls to become dirty and the inconvenience of having to clean them again, as well as the poor working conditions, has led to workers' avoidance, which leads to difficulties in supply and demand and eventually increases construction costs. It caused a problem that caused. In addition, such artificial stone has a problem that the change of the pattern or the color tone is almost limited to satisfy various expression desires of the surface pattern.

이에 본 발명은 상기와 같은 문제점에 착안하여 천연 석재류의 외관 효과와 내구성을 유지하면서도 분무시공법을 이용함으로써 시공이 편리하고, 다양한 표면무늬를 표현할 수 있는 바닥마감재용 조성물을 제공하는데 그 목적이 있다.Accordingly, the present invention has been made in view of the above problems, while maintaining the appearance effect and durability of the natural stone materials by using a spray construction method, the construction is convenient, it is an object to provide a composition for a floor finishing material that can express a variety of surface patterns. .
