Method for manufacturing vibration isolator

Abstract

The invention discloses a method for manufacturing a vibration isolator. The method is as below: first dipcoating 5-10 rubber layers on a whisker surface of tetrpod-like zinc oxide; taking 100 parts by weight of plasticated natural rubber; adding 10-15 parts by weight of the tetrpod-like zinc oxide with rubber layers dip-coated on the whisker surface, 3-5 parts by weight of nano zinc oxide, 0.3-0.8 parts by weight of stearic acid, 15-20 parts by weight of spray carbon black, 1-3 parts by weight of an antioxidant N-phenyl-beta-naphthylamine, 2-3 parts by weight of sulfur and 0.3-0.8 part by weight of an accelerator disulfide benzothiazole; mixing evenly; injecting the mixture into a metal mold cavity of a molding machine injection isolator by an injection molding machine; and vulcanizing the mixture at 150-160 DEG C for 15-20 min to obtain the isolator product. The isolator manufactured by the manufacturing method provided by the invention has strong carrying capacity and high damping dissipation energy, good noise reduction and isolation performance and obvious effects.

Description

(1) Technical field

[0001] The invention relates to a method for manufacturing a vibration isolator, in particular, a method for manufacturing a vibration isolator with four-needle zinc oxide whisker reinforced rubber. (2) Background technology

[0002] With the development of modern industry, vibrating tools and high-power machines that generate strong vibrations are increasing, and the vibration hazards caused by various mechanical equipment during operation and work are becoming more and more serious. In daily life, this kind of vibration and noise will endanger human health and have a great impact on people's life and work. In engineering, the broadband random excitation caused by vibration and noise will cause the multi-resonant peak response of the structure, directly affect the normal operation of electronic devices, instruments and meters, and cause catastrophic consequences in severe cases. In the military, the development of weaponry and aircraft is increasingly h...
