Enhanced reaction bonding cross film wet-paving polymer waterproof coiled material

Abstract

The invention discloses an enhanced reaction bonding cross film wet-paving polymer waterproof coiled material which comprises a cross film base layer, an anti-cracking layer and a bonder layer. The anti-cracking layer and the bonder layer are arranged on the upper surface and the lower surface of the cross film base layer correspondingly. A protective film is bonded and fixed to the upper surfaceof the anti-cracking layer. An isolating film is bonded to the lower surface of the bonder layer. According to the enhanced reaction bonding cross film wet-paving polymer waterproof coiled material, polyester fibers are added into the anti-cracking layer, thus the extending and retracting property of the anti-cracking layer can be improved, and the crack situation of the anti-cracking layer is avoided; and the cross film base layer is arranged to be of a corrugated structure, thus when the paving face of the coiled material cracks, the cross film base layer can be elongated through the corrugated structure, and the stress on the cross film base layer is relieved, fracture of the cross film base layer is avoided, and the waterproof sealing effect of the coiled material is ensured.

Description

technical field [0001] The invention belongs to the technical field of waterproof coiled material, and in particular relates to a reinforced reactive adhesive cross-membrane wet-laid polymer waterproof coiled material. Background technique [0002] Waterproof membrane, a roll of waterproof material made of asphalt, rubber or other organic materials, commonly known as linoleum or linoleum. It has good water resistance and good flexibility. Waterproof membrane is mainly used in building walls, roofs, tunnels, roads, landfills, etc. [0003] For example, the patent with the application number CN201410024006.2 discloses a composite pre-paved waterproof membrane, which includes a modified asphalt polyester tire membrane substrate and a modified asphalt polyester tire membrane substrate. An adhesive layer and a protective layer, the adhesive layer adheres the protective layer to the modified asphalt polyester tire coil base, and the protective layer is granular sand or colloidal ...

AI Technical Summary

Problems solved by technology

[0004] However, the above-mentioned scheme has the following defects in use: if cracks are generated on the paving surface, the coiled material will be stretched, and the base layer of the coiled material in the above-mentioned scheme cannot relieve the tensile stress formed during stretching, which will easily cause cracks in the coiled material Even broken, affecting the waterproof and sealing performance of the membrane
