    • A fire retarded polymer composition is disclosed, which comprises a polymer component, at least one halogen-containing fire retardant and a heat expandable graphite. The polymer component is selected from among polystyrenes, polyesters and polyolefins. The halogen of the fire retardant is bromine or chlorine. , and the total amount of the fire retardant and the heat expandable graphite is from about 6.5 to about 40% by weight. The composition may also contain a metal oxide fire retardant, such as antimony trioxide, but if so, it contains it in amounts much lower than those required in prior art compositions to achieve the same degree of fire retardancy. It is preferred that the heat expandable graphite be such as to expand 50 times or more on shock heating from room temperature to 900oC. The process by which the expandable graphite is produced is not critical, and it is known, for example, to pro duce it by oxidation of natural or artificial graphite.
    • 公开了一种阻燃聚合物组合物,其包含聚合物组分,至少一种含卤素阻燃剂和可热膨胀石墨。 聚合物组分选自聚苯乙烯,聚酯和聚烯烃。 阻燃剂的卤素是溴或氯。 ,并且阻燃剂和热膨胀性石墨的总量为约6.5重量%至约40重量%。 组合物还可以含有金属氧化物阻燃剂,例如三氧化锑,但如果是这样,则其含量远低于现有技术组合物中达到相同程度的阻燃性所需的量。 在从室温至900℃的冲击加热下,优选使膨胀石墨膨胀50倍以上。 制造可膨胀石墨的方法不是关键的,例如通过天然或人造石墨的氧化来制备它是已知的。
