To determine the amount of phosphorus needed to achieve flame retardancy, various amount of DOPO epoxy resin was added to Bis-A epoxy resin and cured with Ph Nov. The mixtures of epoxy resins consisted of Bis-A epoxy/DOPO epoxy (or Bis-A epoxy/ TBBA epoxy) in various weight ratios (87.5/12.5, 77.8/22.2, 71.4/28.6) were prepared. Ph3P was used as a curing accelerator. Each epoxy mixture was mixed with Ph Nov and 0.2% Ph3P in a mill at 25°C to give thermosettable epoxy resin powders. The resin powders were cured in a mold at 150°C and 50 kg/cm2 for a period of 1 h and then at 185°C for 2 h, and further postcured at 210°C for 3 h to obtain cured specimens.
LOI and UL-94V Flame Retardant Test
The LOI is the minimum fraction of O2 in a mixture of O2 and N2 that will just support flaming combustion. The LOI test was performed according to the testing procedure of ASTM D 2836 Oxygen Index Method with test specimen bar of 7–15 cm in length, 6.5 6 0 .5 mm in width, and 3.0 6 0.5 mm in thickness. Ten sample bars suspended vertically were ignited by a Bunsen burner. The flame was removed and the timer was started. The concentration of oxygen was raised if the specimen extinguished before burning 3 min or 5 cm. The oxygen content was adjusted until the limiting concentration was determined.
The UL-94V test was performed according to the testing procedure of FMVSS 302/ZSO 3975 with test specimen bars of 127 mm length, 12.7 mm width, and about maximum up to 12.7 mm thickness. The UL-94V test determines the upward- burning characteristics of a solid. Five sample bars suspended vertically over surgical cotton were ignited by a Bunsen burner; two ignitions with 10 s burning time were applied to each sample bar. The samples of cured epoxy resins with various curing agents of Ph Nov, DDS, and DICY were subjected to the UL-94V test.
不好意思我只有这个能力了：
DOPO 环氧树脂修改过的Encapsulants 的准备
确定相当数量磷需要达到火焰retardancy, 各种各样的相当数量DOPO 环氧树脂增加了来Bis 环氧树脂和被治疗了以酸碱度11月。 环氧树脂混合物包括了Bis 环氧DOPO 环氧(或Bis 环氧 TBBA 环氧) 以各种各样的重量比率(87.5/12.5, 77.8/22.2, 71.4/28.6) 准备了。 Ph3P 被使用了作为一个治疗的加速器。 各个环氧混合物与酸碱度11月和0.2% Ph3P 被混合在一个磨房在25.6aC 给thermosettable 环氧树脂粉末。 树脂粉末被治疗了在一个模子在150.6aC 和50 公斤cm2 1 h 的期间和然后在185.6aC 为2 h, 并且进一步postcured 在210.6aC 为3 h 获得被治疗的标本。
LOI 和UL-94V 阻燃测试
LOI 是O2 的极小的分数在将支持火焰状燃烧O2 和N2 的混合物。 LOI 测试执行了根据ASTM D 2836 氧气索引方法试验过程与测试7.C15 cm 标本酒吧在长度, 6.5 6 0 5 毫米在宽度, 并且3.0 6 0.5 毫米在厚度。 十个样品酒吧垂直暂停被本生灯点燃了。 火焰被去除了并且定时器开始了。 氧气的集中被提高了如果标本被熄灭在烧3 分钟或5 之前cm 。 氧含量被调整了直到限制的集中是坚定的。
UL-94V 测试执行了根据试验过程FMVSS 302/ZSO 3975 与测试127 毫米长度标本酒吧, 12.7 毫米宽度, 并且maximum.up 对12.7 毫米厚度。 UL-94V 测试确定固体的向上灼烧的特征。 五个样品酒吧暂停了垂直结束外科棉花被本生灯点燃了; 二燃烧以10 s 灼烧的时间向各个样品酒吧被应用了。 被治疗的环氧树脂样品与酸碱度11月各种各样的治疗的代理, 二氨基二苯基砜, 并且DICY 接受UL-94V 测试。
