Problems solved by technology

However, in coastal areas or areas with high salinity, salt spray is prone to occur, so the aluminum frame of solar photovoltaic modules installed in coastal areas or areas with high salinity is easy to corrode and peel off, destroying the sealing of the components, and air and moisture enter the backplane After being combined with the EVA encapsulation layer, the encapsulation layer of the module will be aged and yellowed, which will cause the PID effect of the module, the power of the module will decay rapidly, and the service life will be seriously reduced
In addition, the aluminum frames of solar photovoltaic modules used in animal husbandry and agricultural areas with many farms are susceptible to corrosion by ammonia gas generated by the decomposition of organic matter, which not only affects the appearance of the aluminum frame, but also affects the bonding between the adhesive and the aluminum frame. The performance is damaged, so that water vapor, air, etc. enter the solar module, causing oxidation damage to the grid line of the module, resulting in power attenuation of the module and affecting the service life of the module
In addition, the aluminum alloy frame is very easy to conduct electricity, causing the components to leak electricity. If the grounding is not good, it is easily affected by lightning strikes, and the components will be severely damaged.

Abstract

The invention relates to a resin frame, a preparation method, and an application thereof and belongs to the field of photovoltaic materials. The resin frame is composed of, by weight, 80 parts of ABS resin, 10-50 parts of PA6, 20-50 parts of long-glass fibers, 3-20 parts of a compatilizer, 0.3-1.5 parts of an anti-oxidizing agent, 0.5-1.4 parts of an ultraviolet absorber, 0.3-1.3 parts of an impregnating agent, 0.01-0.6 parts of a photo-stabilizer, and 0.5-6 parts of a flame retarder. The ABS/PA6 resin material modified by the glass fibers and the additives is light in weight, has good insulation property and strong flame retarding performance, has strong anti-salt smoke corrosion capability, and can be used as a novel material in a frame of a solar component.

Description

technical field [0001] The invention relates to a frame, in particular to a resin frame and its preparation method and application, belonging to the field of photovoltaic materials. Background technique [0002] At present, a solar photovoltaic module generally includes a laminate and a frame. The laminate may include tempered glass, EVA, a battery sheet, and a back sheet. The laminate is packaged and fixed by the frame and an adhesive. At present, the aluminum frame is commonly used in the solar module frame, mainly because the aluminum frame has the advantages of exquisite appearance, light weight, oxidation resistance and easy installation. However, in coastal areas or areas with high salinity, salt spray is prone to occur, so the aluminum frame of solar photovoltaic modules installed in coastal areas or areas with high salinity is easy to corrode and peel off, destroying the sealing of the components, and air and moisture enter the backplane After being combined with th...
