Problems solved by technology

But the current situation is that most of the rubber buffer plugs are made of natural rubber or styrene-butadiene rubber and cis-butadiene rubber. The rubber hardness is too high, the compressive stress is too large, and the shock absorption effect is poor;
Since the above-mentioned rubber is not resistant to ozone and weather, it will crack early during use, especially with poor flex resistance, and early damage will occur

Abstract

The invention discloses a rubber shock absorption buffering plug and a preparation method of the rubber shock absorption buffering plug and belongs to the technical field of a rubber product. The rubber shock absorption buffering plug is characterized in that the rubber shock absorption buffering plug comprises the following rubber components in part by weight: 60 to 65 parts of natural rubber, 35 to 40 parts of chloroprene rubber, 28 to 32 parts of carbon black, 3 to 4 parts of age resister, 1.3 to 1.5 parts of accelerator, 4 to 5 parts of softener, 4 to 5 parts of zinc oxide, 1.3 to 1.5 parts of vulcanizing agent, 1 to 1.5 parts of stearic acid and 1.5 to 3 parts of processing aid AT-B. The rubber shock absorption buffering plug prepared by mixing the components according to the formulahas reasonable raw material proportion, good ozone aging resistance, weather aging resistance and warping resistance, long service life and simple and reasonable process and can be widely applied to a damping system of a motorcycle, so as to reduce bumpiness, keep running balance and improve the comfort of the motorcycle.

Description

technical field [0001] The invention belongs to the technical field of rubber products, and mainly relates to the technical improvement of rubber shock-absorbing and buffering rubber plugs, in particular to a rubber shock-absorbing and buffering rubber plug and a preparation method thereof. Background technique [0002] At present, the rear shock absorption system of motorcycles is composed of metal springs and rubber buffer plugs. The springs can play a role in shock absorption on flat roads, and the driving is balanced and comfortable. But its current situation is that the rubber buffer plugs are mostly made of natural rubber or styrene-butadiene rubber and cis-butadiene rubber. The rubber hardness is high, the compressive stress is too large, and the shock absorption effect is poor; Because the above-mentioned rubber is not resistant to ozone and weather, it cracks early in the process of use, especially because of poor flex resistance, and early damage occurs.
