Abstract

The invention relates to the technical field of photovoltaic and in particular to a high-toughness weather-resistant plastic photovoltaic bracket which comprises the following components in parts by mass: 50-60 parts of polyethylene resin, 2-10 parts of POM (polyformaldehyde), 10-20 parts of nitrile rubber, 2-10 parts of carbon black, 2-7 parts of barium stearate, 0.2-0.6 part of paraffin, 2-8 parts of glass fiber, 1.2-3.6 parts of talcum powder, 0.8-4.8 parts of a cold-resistant agent, 0.2-1.2 parts of an antioxidant and 0.2-0.8 part of an anti-impact agent. The high-toughness weather-resistant plastic photovoltaic bracket provided by the invention is simple in raw material and reasonable in proportioning; meanwhile, due to addition of the carbon black, the glass fiber, the cold-resistantagent, the antioxidant and the anti-impact agent, not only is the strength of the plastic photovoltaic bracket improved, but also the cold resistance, the aging resistance and the impact resistance of the plastic photovoltaic bracket are improved, the service life of the plastic photovoltaic bracket in stormy weather and extremely cold environments can be prolonged, and the use security of the plastic photovoltaic bracket can be improved.

Description

technical field [0001] The invention relates to the field of photovoltaic technology, in particular to a high-toughness and weather-resistant plastic photovoltaic bracket. Background technique [0002] Fixed photovoltaic support, as the name implies, refers to a support system that maintains the same orientation and angle after installation. The fixed installation method directly places the solar photovoltaic modules towards the low-latitude area (at a certain angle to the ground), and forms a solar photovoltaic array in a series-parallel manner, so as to achieve the purpose of solar photovoltaic power generation. There are many ways of fixing, such as ground fixing methods include pile foundation method (direct embedment method), concrete block weight method, pre-embedded method, ground anchor method, etc. The roof fixing method has different schemes depending on the roofing material . [0003] Most of the existing photovoltaic brackets are made of stainless steel, which ...
