Description
Technical field
The present invention relates to ultrasound examination field, more particularly to a kind of couplant for resistance spot welding ultrasound examination and
Its preparation method.
Background technology
Ultrasonic examination be using the acoustical behavior difference of material and its defect to ultrasonic propagation wave reflections situation and
The energy variation of time of break-through carrys out the lossless detection method of experimental material internal flaw.Generally needed in the Non-Destructive Testing of ultrasonic wave
Couplant is used, the purpose using ultrasonic coupling agent is to fill the slight void between contact surface, does not make these interstitial
Micro-air influences penetrating for ultrasound, the propagation of enhancing ultrasonic wave to detection workpiece, is acted on by " transition " of couplant, makes spy
Acoustic impedance difference between head and detected material reduces, and so as to reduce reflection loss of the ultrasonic energy at this interface, couplant may be used also
" lubrication " effect is played, reduces the friction between probe face and detected material, probe is flexibly slided and detect.
But couplant there are some particular/special requirements in the application for resistance spot welding, can not mainly be corrosive, Yi Qing
The characteristic such as wash, be not easy to flow, it is contemplated that matching and uniformity with the delay block velocity of sound of detection probe.Therefore it is badly in need of a kind of use
Meet above characteristic in the couplant of resistance spot welding ultrasound examination, while it is cheap to prepare simple and cost.
The content of the invention
In view of problem above, prepares low cost, safe to use, easy cleaning the invention provides one kind, improves detection
The neutral of effect is used for resistance spot welding ultrasound examination couplant.Based on glycerine, water and starch mixed solution can make starch without
Bubble gelatinization principle.In order to realize foregoing invention purpose, the present invention provides following technical scheme：It is a kind of in the present invention to be used for point of resistance
The couplant of ultrasound examination is welded, the mass percent of its each component is：Modified starch 2-5%, water 17-21%, glycerine 75-
80%.
The glycerine is that glycerine is medical grade.
The modified starch is food-grade starches.
The wet concentration pure water.
It is 1800m/s~2000m/s that the couplant, which is adapted in ultrasonic velocity,.
A kind of preparation method of couplant for resistance spot welding ultrasound examination, comprises the following steps：S1. starch is taken to add
Enter in water, stirring makes it be heated after being uniformly dispersed, and it is cooled down after being gelatinized and obtains starch fluid；S2. to the starch solution after gelatinization
Middle addition glycerine, stirring make its mixed liquor be uniformly dispersed；S3. boiling water is slowly added into the glycerinum amyli aqueous solution, when adding
It is slowly stirred；S4. after stirring a few minutes, starch is gelatinized completely, cooling.
Starch adds water mixed liquid heating-up temperature to be 65 DEG C in the step S1.
Pay attention to being stirred vigorously when stirring in the step S3, otherwise might have bubble generation.
The advantages of the present invention are to provide a kind of couplant for resistance spot welding ultrasound examination, the coupling
The raw material of mixture is cheap and easy to get, only most common modified starch series on the market, pure natural raw material, has no toxic side effect, security
It is high；Compared to the industrial couplant such as common machine oil, solder joint ultrasonic imaging made of starch mixture provided by the invention is examined
Survey couplant need to only use clear water flushing or paper handkerchief wiping to complete cleaning；The couplant is not perishable in neutrality
Ultrasonic probe and determinand, application are more extensive；The velocity of sound is about 1800m/s~2000m/s, and the delay block sound of probe above
It is fast consistent, it thus can reduce the loss and reflection of ultrasonic propagation.
