Abstract
The invention relates to a novel automobile part electrophoresis process and relates to the field of surface treatment. The novel automobile part electrophoresis process includes the steps of workpiece hanging, ultrasonic wave paraffin removal and oil removal, washing, washing through pure water, purple bronze electrophoresis and drying. Products produced through the process are smooth in appearance, glossy and not prone to fading after being painted, surface films are even in thickness, the utilization rate of electrophoresis tank liquid is high, the oil paint attaching ratio is increased, and salt mist resistance is improved.
Description
Technical field
The present invention relates to field of surface treatment, particularly relate to a kind of new automobile parts electrophoresis process.
Background technology
Electrocoating paint is widely used in industrial circle, and it has less energy-consumption, pollutes little feature, in existing electrophoresis process, pursuing under more less energy-consumption, more oligosaprobic prerequisite, improve the paint adhesive rate of electrocoating paint, improving salt spray resistance ability, is the target that those skilled in the art constantly pursue as far as possible.Existing technique due to the unstable of technique, causes the parts of electrophoresis cannot reach use standard in treating processes.
Summary of the invention
The object of the invention is to the above problem overcoming prior art existence, a kind of new automobile parts electrophoresis process is provided, meets the standard-required of automobile factory.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of new automobile parts electrophoresis process, comprises the following steps:
A, workpiece are hung: clean hanger, put workpiece, check that whether point of contact is good, ensure that workpiece is firm and do not rock;
B, the oil removing of ultrasonic wave paraffin removal: by K-106A: the ratio row of pure water=1:5 carry out joining groove, and temperature controls at 0 ~ 50 DEG C, and selection of time is at 1 ~ 10min;
C, washing: workpiece is entered clean water basin washing, washing time controls at 2 ~ 3min;
D, pure water are washed: the strict pure water conductivity that controls lower than 5 μ s/cm, and enter the last one washing bath specific conductivity before groove must not higher than 10 μ s/cm.
E, copper electrophoresis: adopt red metal mill base: the ratio row configuration electrocoating paint of resin=1:40, add pure water by 5 times of resin and mill base summation again, circulation slaking is produced, and the curing time is 24 hours, construction voltage selects 30 ~ 100V, and tank liquor temperature controls at about 28 DEG C;
F, oven dry: enter drying shed and dry, be divided into preliminary drying and baking-curing two processes, preliminary drying controls at 70-80 DEG C/10min, dries and controls at 170 DEG C/about 30min;
Further, described copper electrophoresis liquid pH value controls 4.2 ~ 4.5.
Further, described electrophoretic paint, except using water as solvent, also adds appropriate organic solvent and makes solubility promoter, improve the water-soluble of resin and painting quality.
The invention has the beneficial effects as follows:
This explained hereafter product out, outward appearance is level and smooth, and superficial film thickness is even, and glossy, not easily fade after japanning, electrophoresis groove liquid utilization ratio is high, improves paint adhesive rate and salt spray resistance ability.
