Title: Method for manufacturing an elastomer using a spacer damper
Inventor: CHO YEON GYU
IPC: C08L23/18
Filed: 2000-02-15
Abstract: PURPOSE: Provided is a preparation method of synthetic rubber for spacer damper by blending anti-oxidant and adjuvant materials with a natural rubber and a butadiene rubber having good anti-abrasive, repulsive tensile strength and flexibility at low temp. The space damper cuts off electric thermal energy due to voltage difference between power transmission lines separately supported by space damper clamp. The synthetic rubber is tear-resistant because it absorbs the abrasion energy generated by the friction of spacer damper clamp and body and has ozone-resistance and the resistance to low temperature. This way lengthens lifetime of synthetic rubber which is inserted into the body and spacer damper clamp. CONSTITUTION: The preparation includes steps of mixing natural rubber with butadiene rubber in a % ratio of 40:60 and auxiliary materials such as 6.0% of aromatic amine and quinoline anti-aging agent against ozone and heat, 50.0% carbon black, 5.0% zinc oxidizer, 1.5% stearic acid, 1.0% octamine, 1.0% paraffin wax, 1.0% polyethylene glycol activator and 1.0% light stabilizer; curing the above mixture in carbon master batch state for 72 hours; cross linking with 3.85% cross linking accelerator such as guanidine, sulfides and insoluble sulfur.
