摘要:
Nonflammable fibers are produced by subjecting a composite fiber comprising a pitch and a synthetic organic polymer bonded uniformly along the longitudinal direction of the fiber to an oxidation treatment to render it infusible and then to a set treatment in air or gaseous nitrogen at a temperature of 200* to 500* C. for at least 2 hours. The nonflammable fiber is converted to carbon fiber by heating to a temperature higher than 800* C. in gaseous nitrogen. Suitable pitches include petroleum asphalt, coal tar pitch, and pitch obtained by baking polyvinyl chloride. Suitable synthetic organic polymers include polyamides, polyesters, polyolefins, polyvinyl chloride, polyvinylidene chloride, polyurethane, epoxy resins, and phenol resins.
摘要(中):
不可燃纤维是通过将包含沥青和合成有机聚合物的复合纤维沿着纤维的纵向方向均匀地进行氧化处理而制成的,以使其不熔化,然后在空气或气态氮气中在200℃的温度下进行固化处理 至500℃至少2小时。 通过在气态氮中加热至高于800℃的温度将不燃纤维转化为碳纤维。 合适的间距包括石油沥青,煤焦油沥青和通过烘烤聚氯乙烯获得的沥青。 合适的合成有机聚合物包括聚酰胺,聚酯,聚烯烃,聚氯乙烯,聚偏二氯乙烯,聚氨酯,环氧树脂和酚醛树脂。
