Abstract
This invention discloses a method for manufacturing an electrostatic powder coating exclusively used on underground valves, which is composed of polyester resin 10-20 wt.%, epoxy resin 20-40 wt.%, specialty curing agent 2-10 wt.%, leveling agent 0.5-1.5 wt.%, titanium dioxide powders 0-25 wt.%, barium sulfate 0-25 wt.%, benzoin 0.2-0.8 wt.%, brightener 0.2-1 wt.%, pigments (carbon black, etc.) 0.1-2 wt.%, wax powders 1-3 wt.% and imidazole 0.05-0.1 wt.%. The electrostatic powder coating is manufactured by mixing the raw materials in a mixer, smelting at 100-130 deg.C for 20-60 s in an extruder and extruding, cooling the extruded sheets, and pulverizing in a pulverizer to powders of 160-350 mesh. The powder coating has such advantages as rust prevention, corrosion resistance and long utilization period.
Description
Technical field
The invention belongs to art of powder coatings, relate in particular to a kind of electrostatic powder dedicated coating and production technique thereof.
Background technology
Underground valve gets rusty easily, corrodes, and just needs in general short duration to overhaul even change, and makes troubles to use, and general application is handled and all do not reached the requirement that extends working time.
Summary of the invention
The technical problem to be solved in the present invention is at above-mentioned deficiency, develops the electrostatic powder dedicated coating of a kind of underground valve.The weight percent of each composition is formed: vibrin 10-20%, Resins, epoxy 20-40%, epoxy phenolics 10-20%, extraordinary solidifying agent 2-10%, flow agent 0.5-1.5%, titanium dioxide 0-25%, barium sulfate 0-25%, st-yrax 0.2-0.8%, brightening agent 0.2-1%, pigment (carbon black etc.) 0.1-2%, wax powder 1-3%, imidazoles 0.05-0.1%.
