Abstract

The invention discloses an aging-resistant PPO-PPS plastic alloy, which is composed of the following components in weight part: 100 parts of PPO, 40-60 parts of PPS, 4-8 parts of compatibilizer and 0.5-1.5 parts of age resister. The aging-resistant PPO-PPS plastic alloy disclosed by the invention is an alloy material with excellent overall performances, mostly retains the advantages of PPS in respects of mechanical property, thermal tolerance, flame retardance and the like, and integrates excellent electrical performances of PPO. The aging-resistant PPO-PPS plastic alloy is suitable for fields of electric appliances such as thermotolerant breaker frameworks and electric appliance connectors.

Description

technical field [0001] The invention relates to a plastic alloy, in particular to an anti-aging PPO-PPS plastic alloy. Background technique [0002] Polyphenylene oxide, referred to as PPO, English name: Polyphenylene Oxide, is one of the world's five general-purpose engineering plastics. It has the advantages of high rigidity, high heat resistance, flame retardant, high strength and excellent electrical properties. In addition, polyphenylene ether also has the advantages of wear resistance, non-toxicity, and pollution resistance. The dielectric constant and dielectric loss of PPO are one of the smallest varieties among engineering plastics, and they are hardly affected by temperature and humidity, and can be used in low, medium and high frequency fields. The load deflection temperature of PPO can reach above 190°C, and the embrittlement temperature is -170°C. As one of the world's top five general-purpose engineering plastics, PPO material is non-toxic and has a low rela...
