Abstract

The invention relates to a glass fiber reinforced PMMA pultruded profile and a manufacturing method thereof. The profile comprises the following raw materials by weight: 15-40 parts of a methyl methacrylate prefabricated material and 60-85 parts of glass fiber; and the methyl methacrylate prefabricated material comprises the following components by mass: 100 parts of methyl methacrylate (MMA), 0.5-5 parts of an initiator, 0.5-5 parts of an internal release agent, 0-5 parts of an ultraviolet light absorber, 0-5 parts of color paste, 0-50 parts of filler and 0-100 parts of a flame retardant. The glass fiber reinforced PMMA pultruded profile is mainly used for but not limited to manufacturing of a solar cell panel frame. The glass fiber reinforced PMMA pultrusded profile obtained by the invention has the characteristics of light weight, high strength, high corrosion resistance and excellent ultraviolet resistance, and is suitable for all occasions requiring higher weather resistance; the profile is convenient to recycle and does not cause environmental damage; and the polymerization temperature is not high, the production energy consumption is low, and greenhouse gas is not discharged in the production process.

Description

technical field [0001] The invention belongs to the field of glass fiber reinforced composite materials, and in particular relates to a glass fiber reinforced PMMA pultrusion profile that can be used for a frame of a solar battery panel and a manufacturing method thereof. Background technique [0002] For devices that need to be exposed to the blazing sun for a long time, they need to have excellent weather resistance, such as solar panels. Solar panels are mainly composed of glass panels, battery panels, back panels, and frames. The frame, as the core fixed component of the solar panel, will withstand sunlight for a long time during use, and at the same time meet the requirements for fixed strength, especially for weather resistance. Sex is extremely demanding. In addition, in order to meet the requirements of large-scale application of solar power generation, the cost of frame materials is also an issue that has to be considered. [0003] Most of the current solar panel ...
