Application of hyperbranched polymer in belt core interface agent of flame-retardant conveying belt

The invention relates to the technical field of flame-retardant conveying belts, and in particular relates to application of hyperbranched polymer in a belt core interface agent of a flame-retardant conveying belt, wherein the hyperbranched polymer is terminated by a silane coupling agent. Polyester cotton canvas is modified by the hyperbranched polymer and can obtain the performance unavailable to common canvas, the bonding strength with a covering layer is greatly improved, and the service life of a conveying belt is prolonged.
