Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

Referring to fig. 1, an embodiment of the present invention is a pre-paved waterproofing membrane, which comprises from bottom to top: the adhesive layer 1, the substrate layer 2, the waterproof layer 3, the reinforcing layer 4 and the protective layer 5. The adhesive layer 1 is a synthetic adhesive for adhering the roll material to a construction surface. Substrate layer 2 is the cloth, and other layers of waterproofing membrane all obtain through further processing on substrate layer 2, adopt the cloth as the toughness that the coiled material can be strengthened to the substrate to be convenient for process.

Waterproof layer 3's major component is pitch, can effectual isolated moisture, plays waterproof effect, is provided with wavy reinforced membrane 31 in the waterproof layer 3, because reinforced membrane 31 is wavy, can effectual promotion coiled material's bearing capacity, plays the supporting role to the coiled material. The material of back up coat 4 is glass fiber, and the help is consolidated the coiled material, and protective layer 5 is metal film, can increase the surface strength of coiled material.

Preferably, the material of the reinforcing film 31 is high molecular polyethylene, the asphalt in the waterproof layer 3 is divided into a plurality of blocks by the reinforcing film 31, and other blocks are not affected after one block in the waterproof layer 3 is damaged.

Preferably, the top of the reinforcing film 31 is adhered to the reinforcing layer 4, and the bottom of the reinforcing film 31 is adhered to the substrate layer 2, so that the reinforcing film can be tightly connected with the coiled material.

Since the reinforcing film 31 is supported in the waterproof layer 3, many voids are formed, and the asphalt is filled in the voids. The asphalt is divided into a plurality of blocks by the reinforced film 31, wherein the damage of one block does not affect the asphalt of other parts, and the influence range of the damaged coil can be reduced, thereby improving the breakage-proof effect of the coil.

The protective layer 5 is a metal film and mainly functions to enhance the surface strength of the coil. The isolation film 51 is arranged on the lower surface of the protection layer 5, and the isolation film 51 is provided with point-shaped protrusions facing the reinforcement layer 4, wherein the point-shaped protrusions can increase the contact area between the isolation film 51 and the protection layer 5, so that the isolation film 41 and the protection layer 5 are connected more tightly.
