PVC type flame-retardant conveyor belt is made by impregnating the whole belt core and plasticizing to form a belt embryo, and then coating the PVC paste with the scraping method, and then re-plasticizing; or adopting the extrusion process, the whole belt core is impregnated and formed by plasticizing. With embryo, it is formed by extruding and laminating plastic covering glue. PVG-type flame-retardant conveyor belt adopts extrusion process, the whole belt core is impregnated, plasticized to form a belt embryo, and it is formed by extruding and laminating rubber cover rubber.
