Embodiment Construction

[0015] In order to make the present invention more comprehensible, the preferred embodiments are described in detail as follows.

[0016] Implementation example 1

[0017] The invention provides an environment-friendly water-based coloring penetrating agent, which is characterized in that the proportioning of each raw material is calculated as follows in parts by weight:

[0018]

[0019] The invention also provides a preparation method for the above-mentioned environmentally friendly water-based coloring penetrant, which is characterized in that it includes the following steps: according to the weight parts, take 90 parts of deionized water and add it to the beaker, turn on the speed of the mixer to 500r.min, and stir while stirring. Add 3 parts of direct sunfast bright red 4B and 0.5 part of weak acid bright red 3GL until they are completely dissolved, then add 3.5 parts of Tween-80 and 3 parts of triethanolamine borate in sequence, and continue stirring for 30 minutes to...

Abstract

The invention provides an environment-friendly water-based coloring penetrant which is characterized in that the environment-friendly water-based coloring penetrant is prepared from the following rawmaterials in parts by weight: one or more of direct fast scarlet 4B, acid red and faintly acid scarlet 3GL of environment-friendly dyes. The invention also provides a preparation method of the environment-friendly water-based coloring penetrant, and the preparation method is characterized by comprising the following steps: adding 75-95 parts by weight of deionized water into a beaker, and adding 2-8 parts by weight of red environment-friendly dye while stirring until the red environment-friendly dye is completely dissolved; and then sequentially adding 3-9 parts of an auxiliary agent and 2-8 parts of an antirust agent, and continuously stirring for 30 minutes to obtain the environment-friendly water-based coloring penetrant. The environment-friendly water-based coloring penetrant replacesthe traditional solvent type penetrant so that direct harm to the body of the user is reduced, and the problem of wastewater discharge after use is mainly solved.

Description

technical field [0001] The invention relates to a preparation method of an environment-friendly water-based coloring penetrant flaw detection penetrant, which is used for detecting opening defects on the surface of workpieces, and belongs to the technical field of nondestructive testing coloring penetrant flaw detection. Background technique [0002] Oil-based colored penetrant for penetrant testing is widely used due to its strong penetrating ability, bright coloring, good wetting performance and high detection sensitivity. Because the solvents used in oil-based colored penetrants are mostly organic solvents such as kerosene, transformer oil, butyl butyrate, dibutyl phthalate, etc., the solute used-coloring dyes, more consideration is the degree of coloring brightness, etc.; so , The waste liquid discharged after use of this type of oil-based colored penetrating fluid pollutes the environment and does not meet environmental protection requirements. The waste liquid of this...
