Manufacturing method of wheel spacer and wheel spacer for heavy equipment

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wheel spacer for heavy machinery having excellent mechanical properties and abrasion resistance, and a method for manufacturing the spacer.;According to the present invention, the wheel spacer includes 35-40 wt% of natural rubber (NR), 25-30 wt% of butadiene rubber (BR), 25-30 wt% of carbon as a filler, and 5-10 wt% of other compounding agents. 40 to 60% by weight of the reinforcing yarn is included in the rubber composition, wherein the reinforcing yarn is a nylon cord including 70% by weight of nylon and 30% by weight of natural rubber. It is characterized in that the arrangement.;Accordingly, the wheel spacer of the present invention has greatly improved mechanical properties, and is excellent in heat resistance, ozone resistance, particularly wear resistance and compression resistance required when contacting the wheel or the ground.
