Abstract

The invention discloses a color steel tile with a graphite coating and a preparation method thereof. The color steel tile comprises a base plate located in a middle layer, and the two sides of the base plate are coated with coatings formed by graphite slurry. The graphite slurry is made of, by weight parts, 50-200 parts of fine flake graphite micro powder, 40-160 parts of cashew-nut oil modified phenolic resin or epoxy resin, 10-50 parts of polyvinyl acetal, 40-160 parts of alcohol, 2-10 parts of coupling agent, 2-10 parts of defoamer, 1-10 parts of plasticizer and 2-10 parts of liquid acrylonitrile butadiene rubber. The service life of the obtained color steel tile with the graphite coating can be greatly prolonged, problems that a conventional resin tile ages easily and is low in strength toughness and not resistant to flame and the like are solved; a problem that a conventional color steel tile is heavy in weight and difficult to install is solved; indoor and outdoor heat exchange rate can also be effectively increased, and a problem of high-temperature poor working environments of conventional color steel tile plants is solved; and a problem that at present, on the market the fine flake graphite is massively accumulated and is low in additional value is solved.

Description

technical field [0001] The invention belongs to the technical field of building materials, and relates to a graphite-coated color steel tile and a preparation method thereof. Background technique [0002] Traditional color steel tiles, also known as colored profiled tiles, are profiled panels that are cold-bent into various wave shapes using colored coated steel plates. The color is bright and beautiful, but it is easy to rust and become a waste product when exposed to bad weather such as acid rain. The general service life is 3-5 years and needs to be replaced. The thermal conductivity is low, only: 0.041w / mk, which undoubtedly makes the factory building with high temperature operation worse. The color steel tile has poor load-bearing capacity and is easy to be damaged. The weight of the tile itself is 10-14 kg / square meter, but it is also difficult to install. [0003] At present, the synthetic resin color steel tiles produced by two-layer co-extrusion technology have en...
