Problems solved by technology

[0002] At present, most of the low-temperature couplant compositions used for ultrasonic flaw detection are oil-based couplants, such as engine oil, transformer oil, grease, etc., but the viscosity index is different, it is difficult to control the amount of use, and it cannot be used at low temperatures, resulting in high cost of use , the flaw detection accuracy is low and even the ultrasonic flaw detector cannot work
It is not only difficult to clean up, but also pollutes the environment and is harmful to the human body.

Abstract

The invention discloses a supersonic flaw detection low-temperature couplant composition and a preparation method thereof. The composition comprises the following raw materials: base oil, benzotriazol, triethanolamine, petroleum sodium sulfonate, barium petroleum sulfonate, diethylene glycol monobutyl ether, and an antifreeze additive. The couplant has the advantages of wide temperature application scope, easy cleaning, good antirust type, and easy usage at low temperature, and is capable of increasing flaw detection precision and ensuring supersonic low-temperature flaw detection effect.

Description

technical field [0001] The invention relates to the field of couplants, in particular to a low-temperature couplant composition for ultrasonic flaw detection and a preparation method thereof. Background technique [0002] At present, most of the low-temperature couplant compositions used for ultrasonic flaw detection are oil-based couplants, such as engine oil, transformer oil, grease, etc., but the viscosity index is different, it is difficult to control the amount of use, and it cannot be used at low temperatures, resulting in high cost of use , The accuracy of flaw detection is low and even the ultrasonic flaw detector cannot work. It is not only difficult to clean up, but also has the problems of polluting the environment and harmful to the human body. Contents of the invention [0003] Based on the existing problems in the prior art, the object of the present invention is to provide a low-temperature couplant composition for ultrasonic flaw detection and its preparat...
