Abstract

The invention provides a polyphenylene oxide composition used for a photovoltaic junction box. The composition comprises the following components by weight: 55-95 parts of polyphenylene oxide, 45-5 parts of styrene resin, 2-10 parts of a flexibilizer, 5-20 parts of a phosphate fire retardant, 0.5-2.5 parts of an acid absorbent, 0.2-0.6 part of a hindered phenol main antioxidant, 0.2-0.6 part of a phosphite auxiliary antioxidant, 0.3-1.5 parts of an ultraviolet absorbent, 0.3-1.5 parts of a hindered amine light stabilizer, 0.1-0.5 part of a lubricating agent, and 0.1-1.0 part of toner. With the characteristics of good flame resistance, thermo-oxidative aging resistance, UV (ultraviolet) resistance, excellent electrical performances, the composition of the invention has flame retardancy up to grade UL945VA, RTI (relative temperature index)=110DEG C, CTI (comparative tracking index) PLC ( programmable logic controller)=2, and GWIT (glow wire ignition temperature)=750DEG C, thus satisfying the requirements in ROHS (restriction of hazardous substances) standard. Thus, the composition provided in the invention can be used for electronic and electrical component production of solar photovoltaic junction boxes, etc.

Description

Technical field

[0001] The invention relates to a polyphenylene ether composition and its use, belonging to the field of polymer alloys. Background technique

[0002] Polyphenylene ether (PPO) has excellent mechanical and electrical properties, but its melt viscosity is high and its fluidity is poor, making it difficult to process and shape. Therefore, various modified varieties are generally used, such as PPO, HIPS, and PP Or PA and other polyphenylene ether alloys have been widely used, and the performance and use value of the blended modified varieties of polyphenylene ether far exceed their own performance and use value.

[0003] At present, ordinary flame retardant and reinforced MPPO materials cannot meet the application requirements of the solar photovoltaic field, that is, water resistance, high flame retardancy, long-term thermal and oxygen aging, UV stability, and high electrical properties such as CTI, GWIT and other properties. It is necessary to further improve the pe...
