The workpiece surface coating method can ensure the workpiece surface coating quality and prolong the service life of the workpiece.
Description
Technical field
The present invention relates to a kind of coating process, particularly relate to a kind of Workpiece interface coating method.
Background technology
Most of workpiece need the surface of workpiece is processed after machining, common coating process is to use cloth to wipe with surface of the work to wipe totally, then antirust paint is directly coated, although this coating process is simple, but there are the defects such as pit in the surface of the work being easy to make, cause surface of the work out-of-flatness, and this coating process can only maintain workpiece at short notice and not receive erosion or non-corrosive, time one is long, antirust paint is easy to be etched or come off, causing that workpiece gets rusty, thus scrapping, workpiece is that service life is comparatively short.
Because above-mentioned defect, the design people, actively in addition research and innovation, to founding a kind of Workpiece interface coating method so that it is have more the value in industry.
Summary of the invention
For solving above-mentioned technical problem, it is an object of the invention to provide one and ensure that workpiece surface spraying quality, extend the Workpiece interface coating method in workpiece service life.
A kind of Workpiece interface coating method that the present invention proposes, it is characterised in that: comprise the following steps:
Step one: to inside workpiece blasting treatment in advance, remove the oxide layer of inside workpiece;
Step 2: surface of the work carries out blasting treatment, removes oxide skin and the rust of surface of the work;
Step 3: the impurity such as the residual rust of surface of the work, greasy dirt are removed clean with acetone;
Step 4: workpiece is dried as in the helium environment of 300 DEG C-400 DEG C;
Step 5: the workpiece after drying is taken out, rust prevention by applying liquid material priming paint on the surface of the workpiece;
Step 6: the workpiece coating anti-corrosive primer is placed under normal temperature condition, natural drying.
As the further improvement of the inventive method, the fineness of sand of step one and the blasting treatment described in step 2 is 0.5-1mm, and compression atmospheric pressure is 0.3-0.66Mpa.
As the further improvement of the inventive method, surface of the work blasting treatment described in step 2 checks after completing, and described detection comprises the following steps:
(1) check that whether sandblasting is complete, complete if any the non-sandblasting of little area, clean with sand papering;
(2) whether detection surface of the work exists the defects such as pit, as being found, carries out blade coating with atomized ash and fills up;
(3), after blade coating fills up, first polish with thicker sand paper, then polish flat with fine sandpaper again.
Further improvement as the inventive method, the operational approach of step (2) is: by clean for rejected region removing surface, remove greasy dirt, moisture, then according to consumption by atomized ash host and sclerosing agent with 100 weight ratio Homogeneous phase mixing than 2-3, finally by intermixture blade coating to defect.
As the further improvement of the inventive method, the drying time described in step 4 is 3-4 hour.
Further improvement as the inventive method, anti-corrosive primer described in step 5 is epoxy aluminium triphosphate anti-corrosive primer, described epoxy aluminium triphosphate anti-corrosive primer includes epoxy primer, firming agent and diluent, and the weight ratio of described epoxy primer, firming agent and diluent is 5:1:3-4.
As the further improvement of the inventive method, the jet size used by rust prevention by applying liquid material priming paint described in step 5 is 1.4-1.6mm, and spraying air pressure is 3-4Pa, and the spraying interlayer time is 15 minutes, and the spraying number of plies is 1-2 layer.
As the further improvement of the inventive method, the time of the natural drying described in step 6 is 16-20 hour.
By such scheme, the present invention at least have the advantage that the inventive method can fully erased surface of the work attachment foreign material, it is possible to uniformly spray anti-corrosive primer, ensure the flatness of surface of the work, ensure the surface coating quality of workpiece, it is prevented that workpiece gets rusty, extend workpiece service life.
Described above is only the general introduction of technical solution of the present invention, in order to better understand the technological means of the present invention, and can be practiced according to the content of description.
Detailed description of the invention
