| Abstract: | Based on the requirement of environmental and weather condition in Qinghai-Tibet railway,PA66 composite with low-temperature resistance and weathering resistance were prepared with POE-g-MAH as main toughener,polymer with epoxy functional group as assisted toughener.The compounded light stabilizer was added in the composite in the meantime.The results showed that the properties of the insulated block made from this composite for railway type I fastener could meet the technical requirement completely. |
