Problems solved by technology

Existing solar cell frames generally use aluminum alloy or galvanized materials. These materials have poor corrosion resistance in humid environments, and their density is high, which increases the burden of floating on water and limits the wide application of solar power generation systems on water.

Embodiment 1

[0037] (1) 30 parts by weight of modified hollow glass microspheres, 3 parts by weight of 2,4-dihydroxybenzophenone, 2 parts by weight of silicone oil, and 4 parts by weight of dibenzoyl peroxide are added to 60 parts by weight of vinyl In the resin, stir at high speed for 30 minutes, and set aside;

[0038] (2) Pass the glass fiber on the creel successively through the yarn collecting board, the layered yarn board, the dipping tank, the preforming mold, the forming mold, and introduce the traction device;

[0039] (3) Put the mixed blending solution into the dipping tank, and the fibers pass through the dipping tank in layers. After dipping, the excess glue is squeezed out step by step through the extrusion roller, and the glass fiber felt is together with the soaked glass fiber. into the forming mold;

[0040] (4) Adjust the forming mold temperature to 120°C, and set the pultrusion speed to 0.6m / min;

[0041] The impregnated glass fiber and glass fiber mat are cooled by th...

Embodiment 2

[0043] (1) 40 parts by weight of modified hollow glass microspheres, 2 parts by weight of 2,4-dihydroxybenzophenone, 1 part by weight of silicone oil, and 3 parts by weight of dibenzoyl peroxide are added to 50 parts by weight of vinyl In the resin, stir at high speed for 30 minutes, and set aside;

[0044] (2) Pass the glass fiber on the creel successively through the yarn collecting board, the layered yarn board, the dipping tank, the preforming mold, the forming mold, and introduce the traction device;

[0045] (3) Put the mixed blending solution into the dipping tank, and the fibers pass through the dipping tank in layers. After dipping, the excess glue is squeezed out step by step through the extrusion roller, and the glass fiber felt is together with the soaked glass fiber. into the forming mold;

[0046] (4) Adjust the forming mold temperature to 130°C, and set the pultrusion speed to 1m / min;

Embodiment 3

[0049] Compared with Example 1, the difference is that glass fibers are replaced by carbon fibers. The density of the prepared solar panel frame is 1.32g / cm 3 , The bending strength is 1550MPa, the mass change rate is 0.91% after soaking in water for 150 days, and the bending after 400h salt spray test is 1525MPa.

[0050] From the above results, it can be seen that the present invention not only has good mechanical properties and low density, but also has excellent corrosion resistance.

The overwater solar cell panel frame has the advantages of good mechanical properties, low density and excellent corrosion resistance, and can well meet the application requirements of water environments, and the production efficiency and theproduct stability can be ensured.

Description

technical field [0001] The invention relates to the technical field of photovoltaic materials, in particular to a solar panel frame on water and a preparation method thereof. Background technique [0002] With the rapid development of the world's population and industrial economy, global warming and the reduction of fossil fuels, people are paying more and more attention to the development of green energy. The sustainable energy system has become an important way to solve the problems of energy shortage and environmental security. However, building a large-scale solar power station requires a large amount of land, and as the world's population continues to increase, the contradiction between more people and less land is becoming more and more prominent. In order to reduce the occupation of land in residential areas, the industry has developed a water solar power generation system. [0003] Water solar power generation systems can be built not only on oceans, but also in fr...
