Easily it is corroded, owing to magnesium is more active than zinc, even if using zinc-rich powder anticorrosion can not pass through 1000 hours neutral salt spray tests so that it is
Application is the most restricted.The new type corrosion resistant magnesium alloy of developing low-cost and combination property has become the work of domestic and international material science
One of focus of person's extensive concern.
Prior art has several to the processing method that Mg alloy surface is the most frequently used, at chemical conversion treatment, anodic oxidation
Reason, organic coating process, electroplating processes, laser treatment, ion implanting etc..Using coating to carry out spraying is that one is the easiest,
Method with low cost.Powdery paints is made up of resin, firming agent, pigment, filler and auxiliary agent etc., through melt extruding, becoming
Type, is coated in material surface as protectiveness and ornamental new coating using pressed powder state.
Prior art is disclosed a kind of novel magnesium alloy anti-corrosive powder paint, and applying the magnesium alloy after this coating can pass through
The neutral salt spray test of more than 1500 hours, but the pencil hardness of this coating only has 1-2H, it is impossible to meet high demand.
It is desirable to provide the high hardness magnesium alloy anti-corrosive powder paint of a kind of excellent performance, it not only has well
Corrosion resistance, also there is the highest pencil hardness.
Summary of the invention
It is an object of the invention to provide the high hardness magnesium alloy anti-corrosive powder paint of a kind of excellent performance, it not only has
Good corrosion resistance, also has the highest pencil hardness.
In order to realize above-mentioned purpose, present invention employs following technical scheme:
A kind of preparation method of high hardness magnesium alloy anti-corrosive powder paint, its step is as follows:
(1) it is equipped with raw material:
According to parts by weight: epoxy resin 50 parts, 12 parts of firming agent, levelling agent 1 part, oxide powder and zinc 12-14 part, Pulvis Talci 10-
12 parts, calcium silicate powder 9-11 part, mullite powder 0.8 part, 2 parts of mafic spinel brick 200 mesh powder, mix homogeneously is standby；
(2) melt extrude:
Extrude at a temperature of 120-150 DEG C with extruder after material mixing；
(3) pulverize with pulverizer after extruded stock cooling is broken be mean diameter be the powder particle of 50 microns；Use 120 eye mesh screens again
Sieve, be finally packaged into finished product.
As preferably, described epoxy resin e44 epoxy resin；
As preferably, described firming agent is phenols curing agent.
The invention have benefit that:
Thering is provided the high hardness magnesium alloy anti-corrosive powder paint of a kind of excellent performance, it not only has good corrosion resistance,
