Technological method for electrostatic powder coating on stainless steel surface

Abstract

A technological method for electrostatic powder coating on a stainless steel surface comprises the steps that: stainless steel is placed into an acid degreasing fluid to remove the surface grease; the stainless steel which is removed with the grease is flushed by clean water, is dehydrated and aired; a metal nanometer finishing agent is painted onto the stainless steel surface; the primary high temperature solidification is carried out; the stainless steel surface after the primary solidification is undergone the conventional electrostatic powder coating; and the secondary high temperature solidification is carried out, so a finished product is produced. The technological method can produce stainless steel decorative materials of various colors, the adhesive forces of the coating and the stainless steel are improved to the zero level, and the practical use requirement is satisfied.

Description

technical field

[0001] The invention relates to metal surface coating treatment, in particular to a process method for electrostatic powder spraying on the surface of stainless steel. Background technique

[0002] Stainless steel is widely used in many fields such as construction, chemical industry, military and machinery because of its characteristics of corrosion resistance, weather resistance, flame retardancy and high strength. In some decoration projects, in order to overcome the defect that stainless steel is not coordinated with some surrounding occasions and environments due to its single color, it is often necessary to spray paint with various colors on the surface of stainless steel to achieve harmony and unity with the surrounding occasions and environmental colors. The effect, but also increase the stain resistance of stainless steel. However, due to its own organizational structure, stainless steel is sprayed with conventional electrostatic powder, and the adhe...
