Abstract
This invention discloses a method for manufacturing an insulated electrostatic powder coating, which is composed of polyester resin 5-20 wt.%, epoxide resion 30-50 wt.%, dicyandiamide 1-3 wt.%, leveling agent 0.7-1.5 wt.%, silicon micropowders 10-30 wt.%, polyvinyl butyral 5-10 wt.%, imidazole 0.05-0.2 wt.%, specialty nonconductive pigments (yellow and green) 0.1-2 wt.% and benzoin 0.2-0.8 wt.%. The method comprises the steps of: mixing the raw materials in a mixing machine according to the formulation, smelting the mixed raw materials in an extruder at 100-130 deg.C for 20-70 s, extruding, cooling the extruded sheets, pulverizing and grinding in a pulverizer to obtain insulated electrostatic powder coating of 100-350 mesh. The equipment of the whole process, including the mixer, the extruder and the pulverizer, should be made of ultrahard and abrasion-resisting materials. Compared with insulated solvent coating, the coating in this invention has better coating capacity and better insulating effects, and is environmentally friendly.
Description
Technical field
The present invention relates to art of powder coatings, more specifically to a kind of electrostatic powder dedicated coating and production technique thereof.
Background technology
Powder coating is that a kind of material surface that is used for rises anticorrosionly, antirust, has protecting materials surface and plays the decoration function solid coating.It dissolves levelling with the Powdered surface that is sprayed at coated article through baking, solidifies the surface of back film forming attached to coated article.Use powder coating and their application to have low in the pollution of the environment, advantages such as production efficiency is high, the easy grasp of application techniques, therefore, be widely adopted in recent years.But insulated type is bad behind the powder coating solidification that generally uses at present, and resistance is increased, and consumes electric power, and protectiveness is not good.
Summary of the invention
The present invention has overcome deficiency of the prior art, and a kind of insulating electrostatic powdered paint and production technique thereof are provided.
