description The invention relates to a fire-retardant and heat-resistant PPO alloy. The fire-retardant and heat-resistant PPO is prepared from raw materials including, by weight part, 55-85 parts of PPO resin, 15-45 parts of PA6 (polyamide 6) resin, 5-35 parts of compound powder, 10-16 parts of fire-retardant agent, 10-16 parts of compatilizer and 0.4-1 part of antioxidant agent, wherein the total weight partoccupied by the PPO resin and the PA6 resin is 100 parts, and the compound powder is formed by premixing barium sulfate, talcum powder, glass fiber powder and silane coupling agent KH550. The fire-retardant and heat-resistant PPO achieves a fire-retardant grade of UL94-5VA and meanwhile is high in heat resistance and tenacity. 本发明涉及种阻燃耐热PPO合金,由包括以下重量份的原料制备而成:PPO树脂55~85份,PA6树脂15~45份,所述PPO和PA6的重量份总和为100份,复配粉体5~35份,阻燃剂10~16份,相容剂10~16份,抗氧剂0.4~1份,所述复配粉体由硫酸钡、滑石粉、玻纤粉与硅烷偶联剂KH550预混而成。本发明所述阻燃耐热PPO合金,其阻燃等级可达到UL94-5VA级,并具有良好的耐热性和韧性。
