Effects Of Bead Wire Surface Morphology,Extraction Speed And Tin Content On The Adhesive Performance Of Rubber

This article have studied the specific surface area,bonding force and physical binding forces which could affect the adhesive performance of the bead wires and rubbers by analysis of the surface fiber tissue morphology of the bead wire.By the results of adjusting the speed of adhesive force extraction test,extraction curve and the formation of fracture morphology which would effect the adhesion properties.Besides all these features,we also changed the content of Tin element in the clad layer to find the regular rule that its potential impact of the adhesion properties or rubber aging.The results shows that different fiber tissues leads to the gap of the adhesion properties of rubber.The tissues with larger specific surface area always own higher adhesive rate and adhesive force while the smaller possess lower ads rate and force.The surface roughness could be used to describe the specific surface area.Flat tissues of the bead wire are not conducive to the adhesion to rubber mean while elongated tissue and particulate tissues are advantageous for adhesion to rubber.The adhesive force extraction curve can be divided into three types due to the effect of rubber strength,fracture position,reaction layer and other factors in the adhesion extraction test.Through the surface fracture analysis of the bead wire extracted from the adhesive force,the specific reason for poor adhesive performance can be confirmed to improve the results.At different extraction speed,the wires and rubber exhibit different adhesion properties.The content of Tin in clad layer can be changed by adjusting the concentration of Stannous ions,the temperature of the solution,the speed of the solution agitator,and the speed of the wire operating.As a results of the experiments,the sizing material from Sailun could satisfy all the features because of its strong adaptability.The adhesion and adsorption change after the aging of Low Tin and High Tin products are basically consistent with the initial adhesion of aging is slightly raised,and then it begins to decrease.
