Problems solved by technology

Due to the limitations of the heat dissipation performance of the injection molding material used in the box body, it affects the heat dissipation performance of the entire junction box
[0006] In order to increase the heat dissipation function of the junction box, some enterprises also install a radiator on the box body of the junction box. The defect of this solution is that the use of the radiator increases the production cost of the junction box and is not conducive to insulation.
Another technical solution is to use a metal shell and a ventilation channel design. Although it can improve the heat dissipation effect to a certain extent, the heat absorption capacity of the metal in the sun will offset the heat dissipation capacity of the metal, and the design of the ventilation hole on the junction box cannot be achieved. Completely waterproof and moisture-proof, which will affect the life of the electrical components in the junction box

Abstract

The invention discloses a photovoltaic wiring box body material. The photovoltaic wiring box body material consists of polybenzyl ether resin, graphene, polystyrene resin, an elastomer, a flame retardant and other auxiliaries. Through the addition of the graphene material into the traditional MPPO (Modified Polyphenylene Oxide), the heat radiatign performance of a wiring box body is improved, and the burnt rate of the wiring box due to poor heat radiation is greatly reduced. Meanwhile, the tenacity and the hardness of the material are improved, and the anti-impact performance of the wiring box is improved.

Description

technical field [0001] The invention relates to a material and a preparation method of a photovoltaic junction box body. Background technique [0002] The junction box plays a very important role in solar cell components. With the rapid development of the photovoltaic industry, more and more attention is turned to the junction box; because it can not only conveniently transmit the electricity generated by the solar cell to the external circuit At the same time, it is also the "bodyguard" of solar cell components. [0003] The photovoltaic junction box mainly includes the junction box body, cables, cable connectors and electrical components in the box. The electrical components in the box mainly include electronic components such as diodes. Due to the particularity of the use of solar cell modules and their own expensive value, photovoltaic junction boxes must have the following characteristics: 1. Strong anti-aging and UV resistance; 2. Excellent heat dissipation mode for ...
