BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-layer composite sheet having a waterproof property,

The present invention relates to a multi-layered composite sheet having waterproof, antistatic and adhesive properties and a waterproofing method using the same to form a triple-structure composite structure for roofing of waterproofing of roofs and other structures of concrete structures. When forming a coat layer or a mortar layer, the solvent of the coat layer blocks the dissolution of the lower second waterproofing layer, the secondary waterproofing and auxiliary barrier function, and the first waterproofing sheet made of nonwoven fabric and PET film A first waterproofing layer, a second waterproofing layer formed of a nonwoven fabric and a synthetic resin film, which functions as a kitchen water and a kitchen root, A melted point bonding layer formed by applying a melt point bonding composition to form a layer on the lower part of the waterproofing layer to bond the waterproofing layer to a concrete layer or a layer of another material; To a multi-layer composite sheet having a waterproof, antistatic and adhesive property, which is a release film layer formed as a release film under the melt point adhesive layer to protect the melt point adhesive layer for storage and transportation, and a waterproofing method using the same.

In recent years, as the construction technology of the civil engineering and construction field has been developed day by day, complex and difficult construction works that have been difficult in the past have been solved. However, toxic waterproofing is often flawed. If the waterproof construction is erroneous, leaks and floods will occur in civil engineering and building structures, and corrosion and damage to the finished structure will occur. Therefore, as the importance of waterproof construction is emphasized in the civil engineering and construction fields, there is a desperate need for the appearance of excellent waterproof materials that can exhibit complete waterproof function continuously until the disassembly of civil engineering and buildings due to a simple waterproof construction .

As the importance of waterproofing system in civil engineering and construction has been evaluated according to the trend of the times, various kinds of waterproofing materials have been developed and used from past to present. However, there are advantages and disadvantages according to respective waterproofing materials, It is urgently required to have excellent waterproof material that has more advantages than disadvantages due to inconvenience.

As a waterproofing material, it mainly used liquid asphalt waterproofing material in the early stage. As a result of the times, waterproofing materials such as asphalt sheet waterproofing materials, various film waterproofing materials, bentonite waterproofing materials and vulcanized and unvulcanized rubber sheet waterproofing materials have been developed. The rubber-based waterproofing material has been evaluated as a waterproof material having excellent properties such as strong tensile strength, tear strength and high elongation, and has been widely used recently, but its price is somewhat disadvantageous.

In addition, the shortage of urban green spaces due to rapid urbanization is becoming a global problem as well as Korea.

Accordingly, the greening industry for building structures has been studied and developed in Europe, North America, and Japan, and according to these technological trends, the importance of rooftop greening is recognized in Korea, .

However, waterproofing and rescue techniques are not yet available. Therefore, when a garden is installed on the rooftop of the structure or the parking lot, leakage of the building structure due to the destruction of the waterproof layer due to the root growth of the plant frequently occurs. Studies in Japan have been actively conducted, and studies are underway to see how strong the plant roots are.

However, most of the waterproofing materials currently being used are damaged by plant roots, and it is known that not only the silk waterproofing material but also the step of the waterproofing layer have a problem. Therefore, there is a need to develop an effective waterproof and root penetration resistance method for preventing cracks, leakage, and damage to waterproof layers of buildings due to the growth of plant roots.

Accordingly, a composite waterproof sheet having asphalt and the like attached to a synthetic polymer resin film sheet exhibiting a high tensile strength, tear strength and elongation at a low cost due to the thinness of the waterproofing material is supplied and supplied. However, And the surface of the polymer synthetic resin film sheet is melted and attached by applying a high heat which is a heat melting method to the joint portion of the sheet to be connected while connecting the sheet to the sheet, I am doing construction.

If the joints of the sheet and the sheet are not uniformly melted and adhered because heat is applied to the polymeric synthetic resin film sheet by applying heat of a high temperature with a torch lamp or a hot air blower in order to attach joints between the sheet and the sheets, Which causes waterproof construction failure.

In other words, the polymer synthetic resin film sheet and the joints to which one end of the sheet is connected are partially waterproofed in the state where the holes are opened due to overheating of the soil lamp or the hot air or the polymer synthetic resin film sheet melts It is waterproofed in the state that it is not waterproof, and the waterproofing construction is completed in a state where the sheet and the sheet are not completely connected to each other.

In order to solve these problems, a multi-layered composite sheet with waterproof, antistatic and adhesive properties has been developed to form a composite structure for roofing of concrete structures or waterproofing and other structures.

However, when the coating layer or the mortar layer is coated on the multilayer composite sheet, the solvent dissolves the underlying layer.

The waterproof room is very limited, and the sheet or PE on the sheet. PET. Or multiple types of thin copper plates (panels) are used in multiple layers rather than a single product.
