불포화 폴리에스테르 수지계 — 강화 플라스틱 — 잔류 스티렌 단량체 함량 측정 不饱和聚酯树脂增强塑料苯乙烯单体残留量的测定

发布日期： 2013-12-31

该标准规定了利用气体色谱法测定聚合状态的不饱和聚酯树脂（以下注明为聚合状态下的UP树脂）增强塑料中残留苯乙烯单体的方法。残留苯乙烯单体是评价UP树脂在聚合状态下架桥程度的重要尺度。这种方法不适合于高耐化学性的UP树脂。

이 표준은 기체 크로마토그래피를 이용해서 중합 상태의 불포화 폴리에스테르 수지(이하 중합 상태 에서의 UP 수지로 명기한다.) 강화 플라스틱의 잔류 스타이렌 단량체의 측정 방법을 규정한다. 잔류 스타이렌 단량체는 중합 상태에서 UP 수지의 가교 정도를 평가하는 데 중요한 척도가 된다. 이 방법 은 높은 내화학성을 가지는 UP 수지에는 적합하지 않다.
