一种无卤无磷覆铜板的制备

摘要

文章介绍所制备的一种阻燃的无卤无磷覆铜板,板材的阻燃性能达到UL94 V-0级,并具有优异的耐热性,玻璃化转变温度达到150℃以上,TGA测试的5%失重热分解温度达到401.3℃,热分层时间T288(带铜)>60 min；并具有优异的加工性能和低的吸水率、成本较普通无卤产品几乎不变.%In this thesis, a halogen-free and phosphorus-free flame-retardant CCL was prepared. The Halogen-free and Phosphorus-free CCL had excellent flame resistance(UL94 V-0), outstanding heat resistance(T288(With Cu>60min), high glass transition temperature(>150℃), high thermal decomposition temperature (>401.3℃), also had good mechanical performance, low coefficient expansion,low water absorption, was as cheap as Normal halogen-Free.
