Description
The present invention relates to a waterproof and antiperspirant composite sheet and a waterproof and antiperspirant method using the same. More specifically, the present invention relates to a waterproof and antiperspirant composite sheet comprising a polyester woven sheet disposed between upper and lower sheets containing a polyolefin composition, A nonwoven fabric sheet, and a waterproof and anticorrosive method using the same.
With the development of industry and rapid urbanization, green space is being reduced. Especially in urban areas, due to the large number of buildings and road facilities, it is difficult to find enough soil to create green spaces. For this reason, there has been an attempt to create a recording space by implanting plants and the like on artificial grounds such as rooftop greening made of concrete or other materials in the city center, and overground greening of the underground structure. The green space on the artificial ground can provide relaxation space for people in the city to relax, and also enables the insect to grow in the city center and expand the ecological environment in which plants can grow.
Since the artificial ground greening is different from the natural planting environment, it has a function of draining the water supplied to the soil so that the plant can grow and a function of preventing the root of the plant from penetrating the ground, Waterproofing and anti-rusting functions are required. However, conventional watertight and free-standing structures are only being used for greening or landscaping applications on building rooftops due to the complexity of the installation process, low economic efficiency, and poor waterproof or anticorrosive performance. These drawbacks are caused by various factors, such as the inconvenience of separately installing the waterproof part and the protruding part, the difficulty of installing the waterproof part firstly installed on the artificial ground, and the many defects caused by installing the waterproof part have. For example, conventionally, in order to planarize and protect the artificial ground during the installation of the waterproof portion, the nonwoven fabric is installed on the artificial ground first and then the waterproof sheet made of synthetic resin is installed on the nonwoven fabric. Further, the nonwoven fabric and the waterproof sheet are fixed together with a nail. In this case, the waterproof sheet is ruptured, and the waterproof performance and the antitheft performance of the web structure are significantly deteriorated. In addition, there is a problem that it is difficult to cover the side wall structure to the edge between the artificial ground and the side wall formed on the artificial ground.
