▎ 摘　　要

NOVELTY - Processing epoxy powder coating comprises (a) using modified agent or dispersant to modify the zero dimensional nanomaterial nano silicon dioxide or nano zinc oxide or diatomite or nano bentonite or one dimensional carbon nano-tube or two-dimensional molybdenum disulfide (MoS2) or oxidation graphene the modified nano material with bisphenol A type epoxy resin, preparing 0.1-3% nanomaterial of the pre-dispersion, (b) weighing the pre-dispersion and epoxy resin based on the design formulation, curing agent, flatting agent, filler, barium sulfate and dioctyl phthalate, melting and extruding the mixture, where the smelting temperature is 95℃, the extruding machine head temperature is 115℃, the material average retention time is less than 20 seconds and (c) cooling the extruded polymer and pressing into tablets, using the transporting the device to the grinder for grinding, screening to obtain the required powder coating product with molybdenum number of 105-108 molybdenum. USE - The method is useful for protecting steel from corrosion. ADVANTAGE - The method: reduces the cost of the coating; has synergistic effect of the ball milling mixing and melt mixing extrusion increases the interaction between molecules; improves the compatibility of the nano-particle and polymer or polymer matrix, which can make the nano material fully dispersed in the powder coating; prevents nano material agglomeration; has simple process, high production efficiency and good modification effect; is economical; can provide a material conveying device; solves the problem of easy to happen damage to reduce the vibration effect of the robot operation and is convenient to travel on the complex terrain. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a material conveying device comprising one end of the chassis (1) is movably connected with one end of the other chassis. A connecting device (2) is movably installed at the joint of the two chassis. A special roller device (3) passes through the disc wall of the chassis and is movably connected with the inner part of the chassis. The bottom of the anti-collision protection layer (4) is fixedly connected to the other end of the chassis. The bottom of the laser locating device (5) is movably mounted on top part. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the material conveying device for processing epoxy powder coating for protecting steel from corrosion.
