Problems solved by technology

[0014] However, when a polyphenylene ether-based resin composition is used as a molding material for a junction structure for a solar power generation module, although it can satisfy thermal and mechanical requirements such as heat resistance and impact resistance, the Insufficient weather resistance
[0015] It is known that when carbon black is blended into a polyphenylene ether resin composition, it can be colored black, and weather resistance such as ultraviolet resistance can also be improved by imparting coloring; however, in the case of blending carbon black, the resistance Tracking tends to decrease

[0264] [Examples 1-30, Comparative Examples 1-10, Reference Example 1]

[0265] The compounding components shown in Tables 1 to 4 were uniformly mixed with a drum mixer in the ratio shown in Tables 1 to 4, and the twin-screw extruder "PCM-30" manufactured by Ikegai Corporation was used. The obtained mixture was melt-kneaded at 280° C. and a rotation speed of 150 rpm, extruded into strands, cooled, cut, and pelletized. In addition, in Tables 1-4, the compounding quantity of the additive other than a polyphenylene ether resin and a styrene-type resin is a compounding quantity with respect to the total 100 weight part of polyphenylene ether resin and a styrene-type resin.

Abstract

To provide a polyphenylene ether resin composition which has excellent mechanical properties such as shock resistance and heat resistance, and has a high degree of blackness, excellent weather resistance, and excellent tracking resistance. [Solution] A polyphenylene ether resin composition formed by including 0.01-5 parts by weight of carbon black (B) and 0.1-20 parts by weight of an alkali earth metal carbonate and / or sulphate (C) per 100 parts by weight of a resin component (A) which has polyphenylene ether resin (a1) as the main component thereof. By combining, in a prescribed proportion, an alkali earth metal carbonate and / or sulphate in a polyphenylene ether resin composition containing carbon black, tracking resistance and shock resistance can be improved.

Description

technical field [0001] The present invention relates to a polyphenylene ether resin composition and its molded article. Specifically, the present invention relates to a polyphenylene ether-based resin composition mixed with carbon black to improve weather resistance while being colored black, and the composition is a polyphenylene ether-based resin composition with increased tracking resistance; The invention also relates to shaped articles thereof. Background technique [0002] In recent years, due to the requirements of environmental protection and energy saving, solar power generation modules for converting the sun's light energy into electricity are installed on the roof of the building, and the energy of sunlight, which is natural energy, is converted into electricity. , as a power source in the building, and at the same time sell the remaining power, this technology has been put into practical use. [0003] In the solar power generation module, in order to extract th...
