Low-smoke low-toxicity coal mine plastic whole-core flame-retardant conveying belt and preparation method thereof
By utilizing the three-layer composite structure and efficient flame-retardant system of the solid plastic flame-retardant conveyor belt, the problems of traditional flame-retardant conveyor belts easily delaminating and producing dense smoke when burning in coal mines have been solved. This achieves a low-smoke, low-toxicity flame-retardant effect, thereby improving safety in coal mines.

AI Technical Summary
Traditional solid-core flame-retardant plastic conveyor belts are prone to delamination and debonding under high load operation, alternating hot and cold conditions, or humid environments, resulting in thick smoke during combustion, which seriously affects visibility in coal mines and hinders escape and rescue.
It adopts a three-layer composite structure of plastic core, core paste layer and capping adhesive. The outer surface of the plastic core is provided with triangular grooves and four-corner pyramidal through holes. The core paste layer passes through the four-corner pyramidal through holes. It is combined with a highly efficient flame retardant system such as zinc phosphomolybdate and zinc borate, and uses plant secretions and peony seed oil to reduce combustion smoke and toxicity.
It significantly improves interlayer bonding strength, reduces delamination and degumming, produces less smoke and has low toxicity during combustion, meets the safety standards for flame-retardant conveyor belts used in coal mines, and ensures personnel safety.
