Abstract

The invention relates to a resin composition, a connection structure for a solar power generation module, and a junction box for a solar power generation module. The present invention addresses the problem of providing a resin composition having both high oil resistance and flame retardancy. The resin composition according to the present invention comprises: (a) a polyphenyl ether resin (a-1) or a mixed resin of a component (a-1) and a styrene resin (a-2); (b) a hydrogenated block copolymer; (c) a phosphate ester compound; and (d) a polyolefin resin in which (a) is 60-90 parts by mass, (b) is 10-40 parts by mass, (c) is 8-25 parts by mass, and (d) is 1-10 parts by mass per 100 parts by mass of the total of the component (a) and the component (b), when the component (a) is a mixed resin, (a-1) is 55-99.95 parts by mass per 100 parts by mass of the mixed resin, the melt flow rate of the component (d) is 30 g/10 min or more, and the phase containing the component (a) forms a continuous phase.

Description

technical field [0001] The present invention relates to a resin composition, a connection structure for a solar power generation module, and a junction box for a solar power generation module. Background technique [0002] In the prior art, polyphenylene ether-based resins have heat resistance, hydrolysis resistance, and flame retardancy in addition to excellent electrical insulation properties, so they are used in electrical and electronic parts such as secondary batteries, solar power generation, and home appliances. / OA equipment has been widely used. [0003] On the other hand, the oil resistance of the polyphenylene ether-based resin composition is insufficient, and cracks or cracks may occur due to contact with the rust inhibitor adhering to the mold of the molding machine, the lubricating oil of various application parts, etc. become a problem. [0004] In response to such a problem, for example, Patent Document 1 describes an oil-resistant resin composition excelle...
