Embodiment 1

[0008] Embodiment 1 The special electrostatic powder described in the present invention, the weight percent of each composition is made up of: polyester resin 30%, epoxy resin 30%, barium sulfate 25%, acrylate 3%, protective wax 1%, titanium dioxide 10%, silver powder 1%.

[0009] The production process of the special electrostatic powder described in Example 1 is: after batching according to the above formula, put it into the mixer for mixing, put the mixed material into the extruder for kneading and extruding, and the extruder The mixing temperature is controlled at 110C, and the mixing time is controlled between 50 seconds; after the extruded flakes are cooled, they are put into a pulverizer for grinding, and ground into a 250-mesh powder intermediate, then taken out and put into a mixer , and then add 3000-mesh silver powder, so that the silver powder and the powder intermediate are fully mixed in the mixer, and finally packed into the warehouse.

Abstract

A special electrostatic powder has weight percent of composition of the mixture of polyester resin and the epoxide resin 50-70%, the filler 20-30%, the leveling agent agent2-5%, the protection wax 0.2-2%, titanium white 5-20%, the silver powder 1-2%. It is produced by: mixing the material in a mixing machine, then putting the mixture into an extruder, next passing into a crasher to be grinded on, last adding silver powder into it, finally, products are obtained. The aesthetic effect and the life are as good as the galvanizing and chroming. None of waste is discharged at all in the process and it is safe to health of the workers.

Description

technical field [0001] The invention belongs to the field of powder coatings, in particular to a special electrostatic powder and a production process thereof. Background technique [0002] Galvanized and chrome-plated on the surface of the product is currently widely used in China, mainly because the galvanized and chrome-plated products are beautiful and have a long service life. However, there are serious three wastes discharged in galvanized and chrome-plated, and it also brings serious health damage to operators. Contents of the invention [0003] The technical problem to be solved by the present invention is to develop a special electrostatic powder and its production process in view of the above-mentioned deficiencies. [0004] The special electrostatic powder of the present invention, the weight percentage of each composition is: the mixture of polyester resin and epoxy resin 50-70%, filler 20-30%, leveling agent 2-5...
