Problems solved by technology

[0007] Existing temperature-sensitive color-changing pigments are relatively susceptible to aging due to environmental factors, among which ultraviolet rays, oxygen, and moisture may cause pigments to fade
Previously, the relevant patents did not provide a clear solution to this problem, but the temperature-sensitive color-changing waterproof membrane needs to withstand the rain and sun, and the aging of the material and the fading of the pigment are important problems that cannot be avoided in use.

Abstract

The invention discloses a TPO waterproof coiled material and a preparation method thereof. The TPO waterproof membrane includes an outer protective layer, an ultraviolet shielding layer, a temperature-sensitive color-changing layer, and a stress-loading layer arranged sequentially from top to bottom. The TPO waterproof membrane of the present invention effectively solves the problem that the temperature-sensitive color-changing dye is easy to age when used outdoors through the cooperation of various functional layers, making the temperature-sensitive color-changing membrane more valuable in use.

Description

Technical field [0001] The present invention belongs to the field of polymer waterproof, and more particularly to a TPO waterproof web and a preparation method thereof. Background technique [0002] The polymer waterproof web is a flexible waterproof material that is formed by rubber and plastic materials as basic raw materials, adding aids and fillers, molding by extrusion, calendering. Common species include EPDM, PVC, TPO, TPV, PE, etc. Compared to traditional asphalt waterproof coils, high-molecular waterproof coil construction is convenient, durable, and beautiful products, and gradually be recognized by architectural and commercial, owners and designers. [0003] TPO waterproof coil, thermochetic polyolefin, is a major raw material with polypropylene, non-vulcanized thermoplastic elastomer, filled with calcium carbonate, magnesium hydroxide, titanium white powder, to extrud out calendering Waterproof web of processing mode. The TPO waterproof coil has the following advantag...
