Description
Technical field
The invention belongs to hybrid coating technical field, particularly to one kind, there is corrosion-resistant, high rigidity, strong adhesive force, black
Color is ornamental, coating layer thickness is micron order, aluminium alloy umbrella frame surface can be played with protection and the face coat of black cosmetic effect
And its preparation and application.
Background technology
At present umbrella frame frame material on the market has five kinds, respectively wooden, irony, aluminium alloy, rustless steel and NEW TYPE OF COMPOSITE
Material, aluminum alloy materials density is low, light weight, intensity high, plasticity is good, it is variously-shaped to be conveniently processed into, thus using the most
Extensively.As umbrella frame Aluminium alloy structural material need to meet corrosion-resistant, wear-resistant, can dicoration etc. require, but without place
The umbrella frame aluminum alloy structural component of reason easily corrodes in moist atmosphere, and aluminum alloy structural component appearance color list
First, processing and manufacturing vestige is obvious, therefore is difficult to meet the requirement of umbrella frame frame material strong corrosion resistant, weather resisteant and high-decoration.
