The invention discloses a processing technology, and relates to the field of conveyor belt processing, in particular to a processing technology of a single-layer canvas rubber conveyor belt. The processing technology of the single-layer canvas rubber conveyor belt comprises the following steps: 1, preparing materials; 2, internally mixing; 3, treating canvas; 4, processing a belt blank; 5, moulding; 6, posttreating. The processing technology is reasonable in design; by the provided processing technology of the single-layer canvas rubber conveyor belt, single-layer canvas is used for replacingmulti-layer canvas, so that bonding of multiple layers is not required; in addition, a bonding adhesive and a covering adhesive have excellent compatibility, so that resources are effectively saved and waste of the resources is avoided.
