Abstract: |
In order to optimize and balance the fatigue resistance of the carcass compound of all-steel radial tire and its adhesion strength with steel cords,the orthogonal test method was used to optimize the adhesive system of the carcass compound.By establishing a crack growth finite element model to calculate the fatigue resistance parameters of the carcass compound and testing its adhesion strength,the range analysis method was used to determine the best dosage of cobalt boroacylate,hexamethoxymethyl melamine(HMMM) and resorcinol formaldehyde resin(RF resin).The results showed that the dosage of cobalt boroacylate,HMMM and RF resin in the optimized adhesive system was 0.3,2 and 1.5 phr,respectively.This optimized adhesive system greatly improved the fatigue resistance of the carcass compound,increased the adhesion strength and realized the balance design of fatigue resistance and adhesion strength. |
