Abstract

The invention provides a waterproof roll and a preparation method thereof, belongs to the technical field of polymer waterproof rolls, and can solve the problems of color fading, color changing, surface staining, microcracking, hairline crack and the like of a conventional TPO (thermoplastic polyolefin) roll product in the use process. The waterproof roll comprises a TPO roll layer, wherein raw materials of the TPO roll layer comprise polymeric TPO resin and a granular auxiliary; the granular auxiliary comprises an antioxidant, a light stabilizer and an ultraviolet light absorber, and the grain size of the granular auxiliary is 0.5-1.5 mm. The waterproof roll has excellent weather fastness, ageing resistance, waterproof function and fastness and reliability in construction.

Description

technical field [0001] The invention belongs to the technical field of polymer waterproof coiled material, and in particular relates to a waterproof coiled material and a preparation method thereof. Background technique [0002] Since the 1990s, thermoplastic polyolefin (hereinafter referred to as TPO) waterproof membrane has developed into the most common single-layer waterproofing for low-slope roofs due to its excellent mechanical properties, welding construction properties, reflection properties and other comprehensive properties. Coil. In our country, with the acceleration of social and economic development, people put forward higher requirements for waterproof products in the construction field, not only requiring waterproof membranes to have excellent waterproof performance, but also requiring their aesthetics and safety. For this reason, TPO waterproof membrane, which represents the highest technology of single-ply roof waterproof membrane, is in a period of rapid g...
