Problems solved by technology

At present, the materials used for solar photovoltaic module frames are mainly aluminum alloy materials. However, the solar photovoltaic module frames made of aluminum alloy materials have the following problems: poor insulation, need to be grounded for lightning protection, and the bias problem caused by grounding installation will promote PID effect; poor corrosion resistance, the anodic oxide film is easily scratched during use, and the corrosion resistance of the scratched position drops sharply; the thermal expansion coefficient is higher than that of glass, the matching is poor, and the shock resistance is poor; impact resistance, fatigue resistance are poor, easy Produces plastic deformation; heavy quality, high price, consumes precious non-ferrous metal resources, is not conducive to the sustainable development of human society, and the aluminum alloy solar module frame cannot be used in harsh environments, find an alternative to the aluminum alloy solar module frame product appears to be important
[0004] In the disclosed patents and documents of solar photovoltaic module frame material replacement, such as Chinese patent CN103214807A, glass fiber reinforced unsaturated polyester material is used, and the surface is coated with fluorocarbon resin as the solar photovoltaic module frame material. Unsaturated polyester Composite materials are light and high-strength, but the process is complicated, the transverse strength is low, and the corrosion resistance is poor; in Chinese patents CN104761880A and CN104760299A, short fibers, long fibers, continuous fiber mats and other reinforced resins are used as solar module frame materials, which can also be The purpose of enhancing the lateral strength, but the process is more complicated, not suitable for widespread use

Abstract

The invention discloses a polyurethane composite solar photovoltaic module frame and a preparation method thereof. The solar photovoltaic module frame is prepared from polyurethane composite, wherein the polyurethane composite is prepared from the following components by weight percent: 10-60% of polyurethane resin and 60-90% of glass fiber twistless continuous roving; the polyurethane resin comprises two components; the component I is isocyanate; the component II comprises polyols, a dewatering agent, a defoaming agent, an anti-ultraviolet agent and a filler. The preparation method of the polyurethane composite solar photovoltaic module frame disclosed by the invention comprises the following steps: respectively injecting the component I and the component II into a mould; arranging the glass fiber twistless continuous roving into a preset shape; soaking resin in the mould and curing for formation; carrying out pultrusion. The polyurethane composite solar photovoltaic module frame is light in weight, high in strength, excellent in insulating property, corrosion resistant and ageing resistant, and replaces an aluminium alloy material, the cost of the solar photovoltaic module frame is greatly reduced, and consumption of non-ferrous metal resource is reduced.
