Extrusion process of extrusion type leaf yellow rubber surrounding bar for liberation shoes
The invention discloses an extrusion process of an extrusion type leaf yellow rubber surrounding bar for liberation shoes. A main rubber surrounding bar and a colored rubber surrounding bar are extruded from an opening cavity which is at 80-85 DEG C, the linear velocity of a rubber piece extruded from the opening cavity is 0.2-0.3m/S, the extruded rubber piece enters a water tank to be cooled after passing through a surrounding bar calendaring roller, and then the extrusion type leaf yellow rubber surrounding bar is acquired finally. According to the extrusion process, special extruding parameters are adopted, an ideal forming effect is achieved, the mechanical property of the rubber material is met, and the color of the rubber material is not influenced. The extrusion process is simple and easy, the cost is low and the using effect is good. 1. A rubber shoes for yellow rubber surrounding strip rubber extrusion leaves the extrusion process, characterized in that the shell around the strip main rubberencircles the strip color rubber extruded from the die, the die temperature is the 80-85 [...] , the linear speed of the die of the extrusion time, 0.2-0.3m/S; extrusion of the film after the casting by the surrounding section from entering into the trough cooling, finally obtained extrusion leaf yellow rubber scarf glue.
