Abstract

The invention discloses a preparation method of a composite material solar photovoltaic module frame. The composite material solar photovoltaic module frame is made of a three-layer composite material, the composite material comprises a polyurethane bottom layer, an adhesive layer and a nanometer protective layer, the polyurethane bottom layer is made of a fiber-reinforced glass fiber reinforced plastic profile, the fiber-reinforced glass fiber reinforced plastic profile comprises, by weight, 100-250 parts of resin, 250-400 parts of glass fiber twistless continuous roving, 25-50 parts of a short fiber, 5-35 parts of an additive and 5-50 parts of an inorganic filler, pultrusion is performed through a pultrusion machine, and the nanometer protective layer is a sharp tetrahedron-shaped nano-particle coating. According to the preparation method, the glass fiber reinforced plastic is pultruded and molded and then coated with the adhesive layer, and then the nanometer protective layer is fixed by using a chemical vapor deposition method, so that the photovoltaic module frame has the characteristics of light weight, high strength, strong weather resistance, good heat dissipation, good wear resistance, strong self-cleaning capability and the like, and the manufacturing cost of the photovoltaic module frame can be reduced.

Description

technical field [0001] The invention relates to the technical field of solar photovoltaic module production, in particular to a method for preparing a composite material solar photovoltaic module frame. Background technique [0002] With the deteriorating environmental situation, people's demand for new renewable resources is becoming stronger and stronger. As a new energy source, solar energy has entered people's field of vision and has been paid more and more attention. In daily life, the solar resources used include solar water heaters, solar street lights and photovoltaic power generation. [0003] With the continuous development of the photovoltaic industry, the system voltage has increased relatively, and the insulation of packaging materials has also become more stringent. In order to solve the problem of scarce land for photovoltaic power plants, it will become a trend to build power plants in harsh environments such as coastal beaches, offshore islands, lakes, pond...
