Description

技术领域 Technical field

本发明属于工程塑料领域，具体涉及一种耐高灼热丝温度的聚苯醚 /苯乙烯类树脂组合物。背景技术 The invention belongs to the field of engineering plastics, and particularly relates to a polyphenylene ether/styrene resin composition resistant to high glow wire temperature. Background technique

聚苯醚具有优异的力学性能、电性能、耐热性、尺寸稳定性和耐候性，广泛应用于电器、办公用品、汽车配件等行业。然而在电子电器中 IEC60695标准的强制执行，电子电器对于其使用的聚合物材料的灼热丝性能要求越来越高。 Polyphenylene ether has excellent mechanical properties, electrical properties, heat resistance, dimensional stability and weather resistance, and is widely used in electrical appliances, office supplies, auto parts and other industries. However, in the enforcement of the IEC60695 standard in electronic appliances, electronic appliances have higher and higher requirements for the glow wire performance of the polymer materials used.

改善聚合物材料的灼热丝性能的研究已有报道，如 US6780905采用 MCA填充 PBT, 可以大幅度提高 PBT的 GWIT, 这里的 GWIT指 glow wire ignite temperture，B卩热丝引燃温度； Research on improving the glow wire properties of polymer materials has been reported. For example, US6780905 uses MCA to fill PBT, which can greatly improve the GWIT of PBT. Here, GWIT refers to glow wire ignite temperture, B卩 hot wire ignition temperature;

CN200810155087采用氮磷阻燃剂协效提高 PBT的 GWIT达到 800°C的要求； US20050004277 提出采用次磷酸盐可以提高聚合物材料的灼热丝性能； CN 200580022444.4中，公开了一种阻燃聚酰胺组合物，包括聚酰胺、包含金属次膦酸盐或者二次膦酸盐和氮系阻燃剂的阻燃剂体系、选自聚 (亚芳基醚)、聚醚酰亚胺、聚醚酰亚胺 /聚酰亚胺共聚物、聚 (亚芳基硫醚)、聚砜、聚醚砜、聚醚醚酮、苯乙烯类抗冲改性剂及其组合中的至少一种芳族聚合物，可以提高该组合物的 GWIT至 IJ 775°C以上。 CN200810155087 The use of nitrogen-phosphorus flame retardant synergistic effect to increase the GWIT of PBT to 800 ° C; US20050004277 proposes to use hypophosphite to improve the glow wire properties of polymer materials; CN 200580022444.4 discloses a flame retardant polyamide composition , comprising a polyamide, a flame retardant system comprising a metal phosphinate or a diphosphinate and a nitrogen flame retardant, selected from the group consisting of poly(arylene ether), polyetherimide, polyetherimide /polyimide copolymer, poly(arylene sulfide), polysulfone, polyethersulfone, polyetheretherketone, styrene impact modifier, and at least one aromatic polymer thereof, The composition can be increased from GWIT to IJ above 775 °C.

上述现有技术中，大多都是加入氮磷阻燃剂来改善聚合物材料的灼热丝性能，其不足之处在于具有高灼热丝温度较低，且其稳定性较差等。另外对于聚苯醚这种常用于电子电器的聚合物材料，很少有专利涉及灼热丝改善的问题。 In the above prior art, most of the nitrogen-phosphorus flame retardants are added to improve the glow wire properties of the polymer material, which is disadvantageous in that the temperature of the high glow wire is low, and the stability thereof is poor. In addition, for polyphenylene ether, a polymer material commonly used in electronic appliances, few patents deal with the problem of glow wire improvement.
