Abstract
A novel composition of recycled thermal-plastic damping material is disclosed. The damping property of the composition remains good from low-frequency vibrations (1 Hz) to high-frequency vibrations (50 Hz) at general operational temperatures. The composition can further be processed by injection molding machines since it is thermal-plastic.
Claims4
A composition of recycled thermal-plastic damping material, the composition comprises:
- (a) 100 parts of polyolefin elastomer, (b) 100 parts of isobutylene-isoprene rubber (IIR);
- (c) 50 parts of thermal-plastic polyurethane (TPU);
- (d) 30 parts of nano-inorganic lamina with a size of 50-250 nanometers;
- and (e) 50 parts of white wax, wherein the composition is mixed by a twin-screw extruder at 200° C., and is processed as a standard sample by injection molding.
