Abstract： |
The present invention relates to a polymer material and its preparation technology. The composite material is prepared using polybutanediol terephthalate resin, polynary epoxy resin, superhigh molecular weight polyethylene resin and low molecular weight polyolefin resin in certain proportion as raw material and through mixing, extruding, melting and pugging in certain temperature, and pelletizing. The said process can improve the heat resistance and wear-resistant self-lubricating property of the composite material to make the polybutanediol terephthalate resin material has high pV value, low friction coefficient and high wear resistance in the harsh condition of high friction load and no oil lubrication. |
