Problems solved by technology

Polyolefin material is a non-polar material, which has poor adhesion to asphalt. In winter, it is easy to cause the bonding strength between the membrane and the asphalt surface to decrease, resulting in delamination.

Embodiment Construction

[0012] A self-adhesive strong high-temperature-resistant nylon composite film for waterproof coils, characterized in that the composite film includes a five-layer co-extrusion layer structure, and the five-layer co-extrusion layer structure is sequentially PIB self-adhesive layer 1, the first adhesive layer Agent layer 2, nylon reinforcement layer 3, second adhesive layer 4 and printing layer 5. According to a preferred embodiment of the present invention, the thickness ratio of the five-layer structure is: PIB self-adhesive layer: first adhesive layer: nylon reinforcing layer: second adhesive layer: printing layer=3:1:2: 1:3. Among them, the first and fifth layers are functional layers, the material price is relatively low, and the proportion is appropriately increased. The middle layer is a structural layer to ensure the mechanical properties and high temperature resistance of the membrane. The second and fourth layers are made of more expensive materials. Adhesive resin, i...

Abstract

The invention discloses a self-adhesive strong high-temperature-resistant nylon composite film for waterproof coils, which is characterized in that the composite film includes a five-layer structure, and the five-layer structure is a PIB self-adhesive layer, a first adhesive layer, Nylon reinforcement layer, second adhesive layer and print layer. The present invention uses a five-layer co-extrusion blowing machine to extrude self-adhesive strong high-temperature-resistant nylon composite film for waterproof coils, without investing in new equipment, and the original equipment can be modified; the self-adhesive strong high-temperature resistant nylon composite film can be laminated The effective balance of strength and peeling strength not only achieves fast packaging, but also has high lamination fastness, and does not require a special heat sealing machine. After the film is attached to the coil, it uses its own viscosity to complete the packaging of the coil; the packaging is convenient, labor-saving, and economical. Human and material resources.

Description

technical field [0001] The invention relates to a waterproof coiled material, in particular to a self-adhesive strong high-temperature-resistant nylon composite film for a waterproof coiled material and a processing method thereof. Background technique [0002] In the production of waterproof membranes, polyolefin (polyethylene hydrocarbon PE or polypropylene PP or ethylene-vinyl acetate copolymer EVA) materials are commonly used as mask materials, but polyolefin materials have problems such as low strength, poor heat resistance and barrier properties. Polyolefin is used as the mask material. In the production of coils, the melting point temperature of polyethylene is ≤135°C, the melting point temperature of polypropylene is ≤165°C, and the asphalt processing temperature of domestic waterproof membrane manufacturers is 160-170°C. Polyethylene materials are in use , can only be processed by cooling the asphalt temperature, the asphalt has poor fluidity, or can only be cold ap...
