Abstract

The invention relates to the technology field of flame retardant conveyor belt and particularly relates to an application of a hyperbranched polymer in antistatic agent on flame retardant conveyor belt. In the application of a hyperbranched polymer in antistatic agent on flame retardant conveyor belt, the general formula of the hyperbranched polymer is CH3(CH2)mN(CH2O)2([CO(CH2)2CON(CH2O)2]m[H]P)2. The hydroxyl-terminated hyperbranched polymer is used as an antistatic agent on PVC conveyor belt, and is directly coated on the surface of a flame retardant conveyor belt to absorb moisture in a mine and then form a more compact and tight conductive water film on the surface of the flame retardant conveyor belt, thus conducting and leaking electrostatic charges efficiently, preventing the accumulation of electrostatic charges and finally reaching the anti-static object.

Description

technical field [0001] The invention relates to the technical field of flame-retardant conveyor belts, in particular to the application of a hyperbranched polymer in an antistatic agent for PVC conveyor belts. Background technique [0002] Flame-retardant conveyor belts are divided into PVC conveyor belts and PVG conveyor belts. The upper and lower covering layers of PVC type are PVC cover rubber, and the upper and lower covering layers of PVG type are both nitrile rubber and PVC. [0003] Flame-retardant and flame-retardant conveyor belts are widely used in coal mines, mines and various factories and enterprises, especially as an important means of transportation in coal mines, because of their advantages such as light weight, long life, good flame retardancy, and less friction. It is made of polyester / cotton integral belt core impregnated with PVC paste and plasticized, then laminated with PVC covering film or rubber and plasticized on a flat plate. However, plastic and...
