TLDR
In this paper, a tungsten-polymer composite material and a preparation method for its preparation is described. But the tungstens powder is not used in the preparation of the material.Abstract:
The invention discloses a tungsten-polymer composite material and a preparation method thereof. The tungsten-polymer composite material comprises the following components in percentage by weight: 20-100% of polymers, 950-1000% of tungsten powder, 0-50% of tungsten fibers, 0.5-5% of coupling agent and 0.5-10% of other auxiliaries, wherein the tungsten powder is prepared through airflow pulverization and surface modification. The tungsten powder disclosed by the invention is good in compaction and flowability and high in loading capacity. The composite material disclosed by the invention is good in physical and mechanical properties, and excellent in weathering resistance, chemical resistance and organic solvent resistance, not only can be applied to the field of ray shielding, but also can be applied to the fields of vibration isolation, weight counterbalance, heat conduction, weapons and ammunitions and the like.read more
