Description
Technical field
The present invention relates to a kind of magnetic powder inspection fluorescence oil base magnetic flaw detection ink and preparation method thereof.
Background technology
The fluorescent magnetic particle flaw detection in the past using all needs testing staff to adopt at the scene a variety of additives, then claimsAmount proportioning, extremely bothers testing staff, and the concentration of proportioning and the very difficult control of suspension, tends to can not get external prison inspectionPersonnel's accreditation.
Summary of the invention
The object of this invention is to provide a kind of safe ready and oligosaprobic magnetic powder inspection fluorescence oil base magnetic flaw detection ink.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: fluorescence oil base magnetcisuspension for a kind of magnetic powder inspectionLiquid, is characterized in that, it comprises solvent and cosolvent, and described solvent is solvent naphtha C7 and machinery oil 10, described cosolventFor emulsifying agent TX-4, defoamer and oiliness fluorescentmagnetic particle(powder), contain by weight:
Solvent naphtha C7:55～70
Machinery oil 10:20～40
Emulsifying agent TX-4:3～6
Defoamer: 1.8～4
Oiliness fluorescentmagnetic particle(powder): 0.15～0.25.
This magnetic powder inspection is divided in aerosol can with fluorescence oil base magnetic flaw detection ink.
The present invention also provides a kind of method of preparing above-mentioned magnetic powder inspection fluorescence oil base magnetic flaw detection ink, and it comprises following stepRapid:
(1), at normal temperatures, by after cosolvent mixing and stirring, place 10 hours stand-by, by solvent and surfactantCarry out mix and blend stand-by after 1 hour;
(2), cosolvent mixed liquor is joined in solvent liquid, then stir 0.5 hour;
(3), then the mixture of magnetic is added in liquid and stirred 1.5 hours again, filter filter with 200 order gauzesExcept residue.
The concentration of the suspension after filtering residue is 0.1%～0.25%.
Beneficial effect of the present invention is: the suspension of the fluorescentmagnetic particle(powder) of magnetic powder inspection use fluorescence oil base magnetic flaw detection ink in carrier fluidProperty is good, makes the workpiece non-corroding phenomenon of detecting a flaw complete. Have mobile, good dispersion, suspension time is long, shows the sensitivity of magnetic traceHigh flaw detecting magnetic powder.
