Title:
TUNGSTEN-HIGH MOLECULAR POLYMER COMPOSITE MATERIAL AND PREPARATION PROCESS THEREFOR
Document Type and Number:
WIPO Patent Application WO/2013/107096
Kind Code:
A1
Abstract:
Disclosed are a tungsten-high molecular polymer composite material and a preparation process therefor. The present invention is composed of the following components by weight ratio: a high molecular polymer 20-100, tungsten powder 950-1000, tungsten fibres 0-50, a coupling agent 0.5-5 and other aids 0.5-10, wherein the tungsten powder used is produced by airflow crushing and surface modification. The tungsten powder in the present invention is highly compacted and flows easily, and is able to bear a high amount of loading. The composite material of the present invention has good physico-mechanical performance and weathering resistance, and good chemical and organic solvent resistance. The material can not only be used in the field of ray shields, but also in fields such as vibration isolation, weight counterbalancing, heat conduction, ordnance and ammunition, etc.
