The content of example and these attached drawings obtain other attached drawings.
Fig. 1 is the flow chart of the spraying method of anti-static coating provided in an embodiment of the present invention.
Specific embodiment
To keep the technical problems solved, the adopted technical scheme and the technical effect achieved by the invention clearer, below
It will the technical scheme of the embodiment of the invention will be described in further detail in conjunction with attached drawing, it is clear that described embodiment is only
It is a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those skilled in the art exist
Every other embodiment obtained under the premise of creative work is not made, shall fall within the protection scope of the present invention.
As shown in Figure 1, including the following steps: the present embodiment provides a kind of spraying method of anti-static coating
S1. entire part to be sprayed is covered using ink；
S2. target spraying area is marked on part to be sprayed；
S3. roughening treatment is carried out to the surface of target spraying area；
S4. coating material is sprayed into target spraying area using heat spraying method and/or cold spraying method, it is anti-to be formed
Electrostatic coating；
S5. the ink of non-targeted spraying area is removed.
In step s 4, heat spraying method can be the methods of electric arc spraying or plasma spraying, be not specifically limited herein.
When coating material is sprayed into target spraying area using heat spraying method, firstly, it is necessary to by Filamentous or powdered coating
Material is heated to melting or semi-molten state, then passes through the power of heat sources itself or the additional high speed gas such as electric arc or plasma arc
Stream is atomized coating material, and sprays the coating material of atomization to target spraying area with the initial injection speed of 680 meter per seconds
Domain, while the temperature of the coating material by temperature control equipment adjusting atomization, make coating material be sprayed into target spraying area
When temperature be maintained in the range of 80 DEG C~220 DEG C, this temperature range can guarantee the physical property and change of part to be sprayed
Performance is learned not change in spraying process.When using arc spray process, coating material is being heated to melting or fritting
Melt before state in filiform.When using plasma spraying method, coating material powder before being heated to melting or semi-molten state
Shape.When using cold spraying method, coating material is being powdered to reaching before target spraying area always, and does not need to heat
To melting or semi-molten state.
The spraying method of anti-static coating provided in this embodiment, is formed using heat spraying method and/or cold spraying method
Anti-static coating, such method are simple and practical.Firstly, in heat spraying method coating material being sprayed with the state of atomization
It is applied to target spraying area, and is to be sprayed into target spraying area with pulverulence in cold spraying method coating material,
And not only uniformity is good but also size is tiny with powdered coating material for atomization, so the uniformity of anti-static coating is good, and
It is easily controllable, anti-static coating is not only substantially increased to the reliability of electrostatic shielding, but also substantially increases yield rate and life
Produce efficiency；Atomization and powder are mainly utilized when secondly as forming anti-static coating using heat spraying method and cold spraying method
The coating material of shape, so the usage amount of other chemical substances is greatly reduced, to reduce environmental pollution；Finally, passing through
Roughening treatment is carried out to the surface of target spraying area, not only contributes to the surface that coating material is attached to target spraying area
On, and the binding force between coating material and target spraying area surface is helped to improve, it prevents anti-static coating from falling off, protects
Demonstrate,prove anti-static effect.
It should be pointed out that the coating material in the present embodiment is zinc or kirsite, in other embodiments coating material
It can be also the materials such as copper, aluminium, silver, stainless steel, copper alloy, aluminium alloy or silver alloy, can be adjusted according to actual needs.Separately
Outside, target spraying area is marked on part to be sprayed, helps to ensure that the accuracy of roughening treatment and spraying position, to mention
The accuracy of high anti-static coating position.It, can be by target spraying area when the surface to target spraying area carries out roughening treatment
