Abstract

The invention relates to the technical field of waterproof rolls, in particular to a TPO waterproof roll with temperature adjustment function and a preparation method thereof. The roll comprises a bottom layer and a surface layer, the bottom layer is a common TPO waterproof roll layer, and the surface layer It is a temperature-adjusting fabric layer, and the temperature-adjusting fabric layer is a fabric layer with a phase-change energy storage material; the preparation method includes: preparation of a temperature-adjusting functional emulsion, compounding of the bottom layer and the fabric layer, spraying of the temperature-adjusting functional emulsion and Winding. The coil of the invention has the function of adjusting indoor temperature while being waterproof, maximizes the utilization of resources, implements low-carbon, green and energy-saving goals, and makes the indoor living environment more comfortable.

Description

technical field [0001] The invention relates to the technical field of waterproof rolls, in particular to a TPO waterproof roll with a temperature adjustment function and a preparation method thereof. Background technique [0002] TPO waterproofing membrane (thermoplastic polyolefin waterproofing membrane) is a new type of waterproofing membrane made of thermoplastic polyolefin synthetic resin polymerized by ethylene propylene rubber and polypropylene as base material, adding antioxidant, anti-aging agent and softener It has the excellent weather resistance, low temperature temperature and the weldability of polypropylene, which completely overcomes the shortcomings of synthetic rubber waterproofing membranes that cannot be welded and synthetic resin waterproofing membranes that are easy to age due to the migration of plasticizers. . Since the outer surface of the TPO waterproof membrane is white, it has a high reflectivity to sunlight. [0003] Cool roof refers to a build...
