Abstract
The present invention provides a method for preparing a high molecular polymer powder material comprising the following steps: adding 20 parts of a high molecular powder material and 0.1 to 10 parts of carbon black into a mixing tank, and performing high-speed stirring for the first time to obtain a high molecular carbon black mixed powder material; adding the high molecular carbon black mixed powder material, 0.1 to 1 part of a flow aid, and 80 parts of a polymer powder material into the powder mixing tank; and performing high-speed stirring for a second time followed by sieving to obtain the high molecular polymer powder material.
