Description

Technical Field

[0001] The present invention relates to engineering plastics, and in particular to a high-strength and corrosion-resistant composite material and industrial products thereof. Background Art

[0002] With the rise of the net-zero carbon emissions trend, governments and companies in many countries have begun to actively develop green energy industries in recent years, including wind power generation, tidal power generation, solar power generation and thermal power generation. Among them, solar power generation is currently the most widely used form by the public in various countries. The existing solar power generation is to set solar panels in places where they can receive sunlight. The most common method is to install the solar panels on the top floor of a building or on farmland.

[0003] Generally speaking, the installation of solar panels usually requires fixing the periphery of the solar panels through brackets, wherein the existing solar brackets are mostly made of aluminum alloy, and an oxide film coating is formed on the surface of the solar bracket, which can block the solar bracket from contacting with the outside air and moisture. Even if the solar panel is exposed to the sun and rain outdoors for a long time, the oxide film coating of the solar bracket has corrosion resistance, which improves the problem of rust on the solar bracket.

[0004] In particular, when the solar panels are installed in coastal areas, the coastal air environment has a high salt concentration, and the sand and fine stones blown up by the sea breeze will destroy the oxide film coating on the surface of the solar bracket, causing the oxide film coating of the solar bracket to fall off abnormally, exposing the aluminum alloy of the solar bracket to the external environment, causing the aluminum alloy to chemically react with water vapor and salt, accelerating the rust rate of the surface of the solar bracket, and correspondingly quickly reducing the service life of the solar bracket. In addition to solar equipment, industrial metal products in coastal areas are also accelerated by the high salt concentration in the air, which makes the surface of the industrial metal products easily rusted, accelerating the reduction of the durability of the industrial metal products.

[0005] Therefore, how to develop materials for solar brackets or industrial products that can withstand harsh environments with high salt concentrations is a technical topic that many related industries are currently focusing on. Summary of the invention

[0013] In one embodiment, the first nylon material includes one or a combination of nylon 6, nylon 66, and nylon 9T; the second nylon material includes one or a combination of nylon 6, nylon 66, and nylon 9T.

Based on the total content of the composite nylon substrate and the composite reinforced substrate, the added amount of the UV absorber is between 0.15 and 0.3 phr, and the added amount of the hindered amine light stabilizer is between 0.15 and 0.3 phr.
