    Abstract: A halogen-free varnish includes (A) resin, (B) curing agent, (C) flame inhibitor (flame-retarding agent), (D) accelerator and (E) additives. Resin of (A) has novolac epoxy resin, DOPO-CNE and DOPO-HQ-CNE. Curing agent of (B) includes Benzoxazine resin and phenol novolac resin. Glass fabric cloth is dipped into the halogen-free varnish so as to form a prepreg with better thermal stability, anti-flammability, low absorbent ability and higher curing rate. Furthermore, the prepreg has more toughness.

    Abstract translation: 无卤清漆包括(A)树脂,(B)固化剂,(C)阻燃剂(阻燃剂),(D)促进剂和(E)添加剂。 (A)的树脂具有酚醛环氧树脂,DOPO-CNE和DOPO-HQ-CNE。 (B)的固化剂包括苯并恶嗪树脂和酚醛清漆树脂。 将玻璃织物布浸入无卤清漆中,形成具有更好的热稳定性,抗燃性,低吸水能力和较高固化速度的预浸料。 此外,预浸料具有更多的韧性。
