Abstract

The invention discloses a TPO composite metal plate which sequentially comprises a metal plate, a polymer adhesive film layer, a TPO layer and an anti-fouling hydrophobic film layer from bottom to top. The TPO layer and the metal plate are bonded through a polymer adhesive film layer; the anti-fouling hydrophobic membrane layer is connected with the TPO layer through thermocompression bonding or co-extrusion; the TPO layer is prepared from the following raw material components in parts by weight: 30 to 50 parts of TPO elastomer, 5 to 20 parts of POE (Polyolefin Elastomer), 15 to 25 parts of filler, 5 to 10 parts of titanium dioxide, 5 to 10 parts of maleic anhydride grafting material and 0.5 to 1 part of antioxidant; the preparation raw materials of the anti-fouling hydrophobic membrane layer comprise the following components in parts by weight: 30-50 parts of fluorine modified hydroxyl organic silicon resin, 10-20 parts of a silane coupling agent, 40-60 parts of an organic solvent, 30-60 parts of deionized water and 2-5 parts of a catalyst. The TPO composite metal plate has excellent water resistance, corrosion resistance, weather resistance and pollution resistance, and is high in strength, good in impact resistance and long in service life.

Description

technical field [0001] The invention relates to the technical field of film-coated metal plates, in particular to a TPO composite metal plate. Background technique [0002] Solar photovoltaic power generation can provide clean power for enterprises and residents, and is recognized as a clean energy source all over the world. In China, thanks to the support of national policies and the continuous development of photovoltaic technology, the application benefits of photovoltaic technology have been significantly improved, and the large area of ​​idle roofs of industrial plants have become the best choice for installing photovoltaic modules. At present, the roof structure of large-area workshops and public facilities buildings, which are the main carriers of roof solar power generation, is mainly traditional metal sheet roofs; considering that once the roof solar system is installed to generate electricity and put into use, it is difficult to control the roof in use. Renovation...
