AI Technical Summary

Technical Problem

The existing subframe connecting bushings for new energy vehicles have insufficient wear resistance and poor aging resistance, failing to meet the multiple requirements of high load-bearing capacity, wear resistance, aging resistance, vibration reduction, and noise reduction.

Method used

Using a modified polyurethane solution as the matrix, modified nano-silica, modified multi-walled carbon nanotubes and polytetrafluoroethylene micro powder are added. The mixture is uniformly mixed by ultrasonic dispersion and mechanical stirring. Anti-aging agents and dicumyl peroxide are added for crosslinking to prepare a high wear-resistant and anti-aging new energy vehicle subframe connecting bushing.

Benefits of technology

The wear resistance and aging resistance of the subframe connecting bushings have been improved, enhancing mechanical properties and operational stability to meet the high load-bearing and NVH requirements of new energy vehicles.

Abstract

The invention relates to the field of auxiliary frame connecting bushings, in particular to a high-wear-resistance anti-aging new energy auxiliary frame connecting bush and a preparation method thereof, and aims at solving the problems that an auxiliary frame connecting bush is insufficient in wear resistance, poor in anti-aging performance and the like. The preparation method comprises the following steps: by taking a modified polyurethane solution as a matrix, sequentially adding modified nano silicon dioxide, modified multi-walled carbon nanotubes and polytetrafluoroethylene micro powder, uniformly mixing through ultrasonic dispersion and mechanical stirring, adding an anti-aging agent and polypropylene glycol dicyclohexyl acetate step by step, and sequentially stirring and uniformly mixing, so as to obtain a finished product. And adding dicumyl peroxide as a cross-linking agent, stirring until the system is uniform, injecting into a mold, carrying out thermal insulation cross-linking and vacuum drying, and demolding to obtain the high-wear-resistance anti-aging new energy auxiliary frame connecting bushing. The high-wear-resistance anti-aging new energy auxiliary frame connecting bush has the characteristics of high wear resistance and aging resistance and excellent mechanical strength and use stability.
