Abstract

The invention relates to the technical field of photovoltaic, in particular to a novel flame-retardant plastic photovoltaic support frame. The support frame consists of the following components in parts by mass: 30-50 parts of polyvinyl chloride, 10-20 parts of polypropylene, 10-20 parts of graphene, 1-6 parts of nano silicon dioxide, 1-8 parts of calcium oxide, 2-6 parts of magnesium oxide, 2-5 parts of talcum powder, 2-4 parts of a heat stabilizer, 0.2-0.6 part of an antioxidant, 1-3 parts of maleic anhydride, 0.2-0.8 part of sodium alginate, 1-6 parts of asbestos powder, 1.2-3.2 parts of aflame retardant and 0.2-0.8 part of an anti-cracking toughening agent. The novel flame-retardant plastic photovoltaic support frame disclosed by the invention is reasonable in raw material proportionand has easily available raw materials; tensile strength of the plastic photovoltaic support frame is improved through addition of the graphene and the nano silicon dioxide are added; and meanwhile, the calcium oxide, the magnesium oxide, the talcum powder, the heat stabilizer, the antioxidant, the asbestos powder and the flame retardant are added, so that the flame-retardant grade of the plasticphotovoltaic support frame is greatly improved, and use safety of the plastic photovoltaic support frame is effectively improved.

Description

technical field [0001] The invention relates to the field of photovoltaic technology, in particular to a novel flame-retardant plastic photovoltaic bracket. Background technique [0002] The solar photovoltaic support is a special support designed for placing, installing and fixing solar panels in the solar photovoltaic power generation system. The general materials are aluminum alloy, carbon steel and stainless steel. 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 .
