Abstract

The invention discloses a heat-resistant microwave-radiable conveying belt for microwave exfoliated graphite and a manufacturing method of the conveying belt. The conveying belt is formed by connecting conveying belt chain links with polypropylene pin shafts (3); the conveying belt chain links consist of polypropylene chain link parts and heat insulation layers; and the heat insulation layers are aluminum silicate fiber blankets (1). The method comprises the procedures of raw material drying, plastification, injection mold filling, and cooling treatment. The conveying belt has the characteristics of high strength, high tensile strength, good high-temperature oxidation resistance, high chemical stability, long service life, easiness and simplicity in operation, easiness in forming, low manufacturing cost, and the like. The conveying belt can replace the conventional conveying belt in the current microwave exfoliated equipment to be applied to the production of the microwave exfoliated equipment, and has important practical significance in boosting the industrial application of the microwave equipment.
