Abstract

The invention discloses a colorful thermoplastic polyolefin (TPO) waterproof coil which is of a three-layer structure. TPO coil layers are arranged on the upper surface and the lower surface of the colorful TPO waterproof coil, a fiber fabric reinforcing layer is arranged in the middle of the colorful TPO waterproof coil, and the TPO coil layer on the upper surface and / or the TPO coil layer on the lower surface are / or colorful. The TPO waterproof coil disclosed by the invention has good processing property, excellent mechanical property, welding construction property and ageing resistance, and good color retention property, and the attractiveness and the designability of projects are improved.

Description

technical field [0001] The invention relates to a polymer waterproof coiled material, in particular to a colored thermoplastic polyolefin waterproof coiled material, which belongs to the field of waterproof chemical materials. Background technique [0002] TPO waterproofing membrane is the latest polymer waterproofing membrane. It has become one of the main materials of single-ply roofing system due to its excellent weather resistance and low temperature performance of EPDM waterproofing membrane and excellent welding performance of PVC waterproofing membrane. . At present, TPO waterproof membranes are mostly white on the upper surface and gray (black) on the lower surface. The singleness of the color limits the design and aesthetics of the project. [0003] With the development of modern buildings and related construction technologies, customers have higher and higher requirements for the quality of buildings, not only requiring waterproof membranes to have excellent water...
