含磷酚醛树脂化合物及以其为原料制备的含磷阻燃环氧树脂固化物
摘要：
本发明涉及一种新型含磷酚醛树脂化合物，其具体结构如下：该化合物由苯酚类化合物、双酚类化合物与甲醛合成酚醛树脂，然后将酚醛树脂与芳香性磷酸酯化合物混合进行缩聚反应制得，可用作环氧树脂的固化剂。本发明还涉及一种含磷阻燃环氧树脂固化物，是将上述含磷酚醛树脂化合物单独或与常规环氧树脂固化剂混合，与环氧树脂在高温下进行反应制得。该含磷阻燃环氧树脂固化物各方面性能优异，绿色无污染，可以作为集成电路板以及半导体的封装材料使用。
摘要（英）：

The present disclosure provides a phosphor-containing phenol formaldehyde resin compound having a general formula (I): The compound is formed of a phenol formaldehyde resin and an aromatic phosphate compound by performing a condensation reaction, which may be used as a curing agent of an epoxy resin. The phenol formaldehyde resin is formed of a phenolic compound, a bisphenol compound and formaldehyde. The present disclosure further provides a phosphor-containing phenol formaldehyde resin cured material which is formed of the phosphor-containing phenol formaldehyde resin compound and an epoxy resin under a high temperature. The phosphor-containing phenol formaldehyde resin compound is added separately or mixed with an epoxy resin curing agent.
