Title:
VIBRATION-DEADENING MATERIAL COMPOSITION
Document Type and Number:
Japanese Patent JP3177620
Kind Code:
B2
Abstract:
PURPOSE: To obtain a composition suitable for automobiles, household electric appliances, having high vibration damping properties by blending an ethylenic copolymer with a hydrocarbon resin, a petroleum-based resin, etc.
CONSTITUTION: (A) 100 pts.wt. ethylenic copolymer is blended with (B) 100-300 pts.wt. resinous substance having 90-120°C softening point obtained by blending a hydrocarbon resin having 115-145°C softening point with a resin selected from an aliphatic petroleum resin, an aromatic petroleum resin, an aliphatic aromatic copolymer-based petroleum resin, a terpene-based resin and a coumarone-based resin having 50-100°C softening point obtained by polymerizing 100 pts.wt. raw material oil having 60-90% indene content prepared from distillate having 140-220°C boiling point among cracked petroleum distillate of cracking of petroleums in the presence of 4-10 pts.wt. phenolic compound by using a Friedel- Crafts catalyst.
