Problems solved by technology

But these metal materials have their inherent disadvantages: due to the migration of metal ions, the metal frame will bring a stronger PID effect
[0003] CN 104467641A discloses a firm and strong solar frame, which is composed of the uppermost layer of solar cell panels, the adhesive of the middle layer and the lowermost layer of non-ferrous metal structural material. The non-ferrous metal structural material layer is an aluminum alloy profile, the solar panel layer accounts for 35%-46% of the total weight of the strong and reliable solar frame, and the adhesive accounts for 14% of the total weight of the strong and reliable solar frame -20%, the non-ferrous metal structure material layer accounts for 36%-47% of the total weight of the solid and strong solar frame, such a frame will still bring a relatively serious PID effect due to the metal material
[0004] In addition, the density of metal is higher, the overall quality of components is greater, and the logistics cost is higher; the metal smelting of steel and aluminum is a production process with high energy consumption, which itself is inconsistent with the purpose of sustainable new energy
[0005] Faced with this problem, it is an effective way to use more new environmentally friendly and recyclable materials to replace the original metal materials as much as possible, especially polymer-based composite materials, whose excellent mechanical properties can fully meet the requirements. However, traditional polymer materials have poor performance in terms of UV resistance and anti-aging. How to improve the performance of the frame in terms of thermal oxygen aging resistance, ozone aging, etc., and improve its service life is the focus of research in this field.

Description

technical field [0001] The invention belongs to the technical field of solar cells, and relates to a composite material for solar modules, a solar module frame and a preparation method and application thereof. Background technique [0002] With the wide application of solar modules, the use of solar frames has attracted a lot of attention in the industry. Traditional solar modules use frames made of metal, mainly products made of metal such as aluminum alloy and stainless steel. Their main function is to improve the overall structure. Protection, improve the overall mechanical strength, and prevent dust, impurities, water, etc. from entering the interior of the component. But these metal materials have their inherent disadvantages: due to the migration of metal ions, the metal frame will bring a stronger PID effect. [0003] CN 104467641A discloses a firm and strong solar frame, which is composed of the uppermost layer of solar cell panels, the adhesive of the middle layer ...
