Development of Rubber Cushion Track for rubber paver machine.
Rubber paver machine is an advanced equipment in road construction. The part of the equipment contacting the road surface mostly uses rubber buffer tracks, that is, a rubber layer is attached to the surface of the metal track, which can reduce the wear of the metal track shoes and prolong the service life, but also improve the buffer capacity of the track and achieve the purpose of shock absorption. In addition, after the rubber layer is damaged, the metal track shoe can still be refurbished and used repeatedly.
According to user requirements, and referring to the performance requirements of rubber crawlers for tanks and armored vehicles, the performance indicators of this product have been formulated: Shore A hardness 70 ~ 80 degrees; tensile strength > 20 MPa; elongation at break > 300%; pull Permanent deformation at break <30%; Akron wear <0125cm3; bonding strength with metal framework >6112MPa.
The construction conditions of the rubber paver machine are harsh, and the track rubber is required to have good mechanical properties;The product is used outdoors for a long time The state requires good aging resistance; the torsion and shear forces during operation are very large, and the rubber and metal track shoes are required to have good adhesion properties. Based on these three principles, the vulcanization system, rubber compound and adhesive performance test were carried out. Because the coating is thicker, you must pay attention to the vulcanization speed and scorch performance of the rubber when choosing the formula.
