S2: choose industrial iron and use electric arc spraying equipment to carry out electric arc spraying process to the aluminum products after S1 process this industrial iron.
S3: use emery wheel to carry out frosted process to the aluminum products after S2 process.
S4: to the preheating 30 minutes under the environment of 50 DEG C of the aluminum products after S3 process.
S5: adopt organosilicon to spray the aluminum products after S4 process, spraying air pressure 2kg/cm2, spray distance 20cm, envrionment temperature 25 DEG C, relative humidity 60%.
S6: under temperature is 280 DEG C of environment, sintering is solidified 6 minutes to the aluminum products after step S5 process, namely complete processing treatment and obtain finished product.
Preferably, the air pressure of sandblasting in step S1 is 6kg/cm2, rotating disk frequency 25Hz, distance 20cm, time 10S.
Preferably, after step S1 sandblasting the outer surface roughness of aluminum products between 2.5 μm ~ 5.0 μm.
Preferably, in step S2, in industrial iron every part, chemical composition mass ratio is Fe >=98.2%, C≤1.8%.
Preferably, the spray distance 15cm of electric arc spraying process in step S2, pressure 6kg/cm2.
Preferably, step S3 medium plain emery wheel selects 180# emery wheel.
The present invention compared to the beneficial effect of prior art is:
A kind of aluminum products process of surface treatment of the present invention, can reach reduction production cost, reduces operation, does not produce injury simultaneously to environment.
Accompanying drawing explanation
Fig. 1 is the cross section metallographs of aluminum products after treatment process of the present invention.
