摘要
运用磷阻燃、成碳阻燃和橡胶增韧技术,制备一种无卤阻燃的改性环氧树脂胶粘剂,应用于聚酰亚胺薄膜基挠性覆铜板中,考察了涂胶厚度及固化工艺对板材性能的影响,得到合适的固化条件是160℃、2 h。板材不含有卤素,具有优秀的剥离强度、耐折性、耐化学性、耐热性和电性能,阻燃性达到UL94 V-0级,性能达到IPC-4204A标准要求。
The halogen-free flame-resistant adhesive was prepared by the technology of phosphorus flame-retardant, Charring flame-retardant, and rubber toughened. The adhesive was applied on polyimide film based flexible copper clad laminate （FCCL）. Studying on the impact of adhesive thickness and curing conditions on the FCCL performance, and the best curing condition was 160 ℃, 2 h. The test results of general properties of FCCL showed that it was halogen-flee, had high peel strength, excellent folding endurance, chemical resistance, solder resistance and electrical properties, flame retardancy achieved UL94 V-0 level, and compatible with IPC-4204 standard.
