Problems solved by technology

At present, most industrial couplants mainly exist in the form of engine oil, transformer oil, grease, glycerin, water glass or industrial glue, chemical paste, etc. Since the rail detector travels faster, the disadvantages of using the above-mentioned industrial couplants are as follows : The sound transmission effect is not good, and it is difficult for ultrasonic waves to penetrate into the workpiece; a large amount of solids are precipitated at low temperatures, which greatly affects the accurate detection of rail conditions

Abstract

The invention discloses an industrial coupling agent for detection of steel rails. The industrial coupling agent is prepared from the following components in parts by weight: 40 to 60 parts of ethylene glycol, 40 to 50 parts of water, 3 to 8 parts of glycerin, and 1 to 2 parts of antirust agent, and further prepared from trimethylolpropane; based on the total weight of the industrial coupling agent for the detection of the steel rails, the weight content of the trimethylolpropane is 0.5wt% to 3wt%. The invention also discloses a preparation method of the industrial coupling agent for the detection of the steel rails. The industrial coupling agent for the detection of the steel rails has the advantages that the sound transmission effect, antirust and anticorrosive properties, and low temperature-resistant property are excellent; the application prospect is broad.

Description

technical field [0001] The invention relates to an industrial couplant, in particular to an industrial couplant for rail flaw detection and a preparation method thereof. Background technique [0002] Ultrasonic testing equipment adopts the latest high-performance, low-power microprocessor technology, based on the principle of ultrasonic pulse reflection, can measure the thickness of metals and other materials, and can also measure the sound velocity of materials. When the ultrasonic pulse emitted by the probe passes through the couplant and reaches the rail, the pulse is reflected back to the probe to determine whether the tested rail is intact or not by accurately measuring the propagation time of the ultrasonic wave in the couplant. [0003] There are two types of couplants, medical couplants and industrial couplants. The medical couplant is a medical product composed of a new generation of water-based polymer gel. The industrial couplant is used to remove the air between...
