Abstract

The invention discloses a mining metal / polymer composite conveyor track supporting roller and a manufacturing method thereof. The raw material includes PVC (Polyvinyl Chloride) resin, waste metal powder or iron-based metallurgy powder, methyl methacrylate-butadiene-styrene polymer, antistatic fire retardant nylon, polyethylene chloride resin, lubricant, plasticizer and composite stabilizer in weight proportion. the manufacturing method of the mining metal / polymer composite conveyor track supporting roller comprises the following steps of: carrying out ball milling and high-temperature degreasing on the metal powder, and firstly mixing the treated metal powder by heating with the PVC resin, the methyl methacrylate-butadiene-styrene polymer, the polyethylene chloride resin, the lubricant, the plasticizer and the composite stabilizer to 115-125 DEG C and then mixing by cooling to 40-60 DEG C; extruding by a twin screw extruder to obtain metal polymer core layer material; mixing antistatic fire retardant PA6 particle material by heating to 125-135 DEG C and removing humidity, then mixing by cooling to 40-60 DEG C, extruding by a single screw extruder to obtain antistatic flame retardant PA6 surface layer material; extruding the core layer material and the surface layer material by a composite extruder to obtain a composite pipe; and processing the composite pipe by cooling sizing, traction and cutting and other following processes of a general method into a finished product according to the specification of a track supporting roller. The composite track supporting roller is higher than a PVC composite track supporting roller by 25 percent in comprehensive physical performances of static resistance, flame retarding, strength and ware resistance, and can be widely applied to the fields of coal mines, oil fields and mines.

Description

Technical field: [0001] The invention belongs to the field of macromolecular materials, and in particular relates to a belt roller of a metal / polymer composite conveyor used in mines and a preparation method thereof. technical background: [0002] Coal mines, oil fields, and mines have harsh environments, and the country has clear safety and use standards for the equipment and pipes used. At present, the conveyor rollers used in coal mines, oil fields, and mines are mostly made of steel, PE, and PVC. These steel products or plastic products have their own disadvantages. Among them, steel products are easy to corrode, high in cost, and noisy in operation. Friction and collision with belt buckles can easily generate sparks, which has great safety hazards in coal mines, oil fields, and mining applications, and is easy to rust and has a short service life; the production of PE products depends on petroleum, which is a strategic material for national energy , the disadvantages a...
