Abstract
The invention provides an environment-friendly water-based coloring penetrant which is characterized by comprising the following raw materials in parts by weight:
Description
Technical Field
The invention relates to a preparation method of an environment-friendly water-based dye penetrant for flaw detection, which is used for detecting the surface opening defects of workpieces and belongs to the technical field of nondestructive testing of dye penetrant flaw detection.
Background
The oil-based coloring penetrating fluid for penetration detection is widely applied due to the characteristics of strong penetration capability, bright coloring, good wetting property, high detection sensitivity and the like. Because the oil-based coloring penetrating fluid mainly uses organic solvents such as kerosene, transformer oil, butyl butyrate, dibutyl phthalate and the like, and the solute-coloring dye is more considered to be coloring brightness and the like; therefore, the waste liquid after the oil-based coloring penetrating fluid is used is discharged, pollutes the environment and does not meet the requirement of environmental protection. The waste liquid of the oil-based coloring penetrating fluid is difficult to degrade. Even though the wastewater passes through a general wastewater treatment system, the wastewater hardly reaches the discharge standard; the discharge requirement can be met only by the treatment of related professional chemical sewage treatment projects. The sewage treatment project has large floor area, complicated treatment procedures, high cost and the like, and brings great burden to the penetration detection enterprises.
With the development of society, environmental problems are more and more prominent, and the environmental awareness of enterprises is increasingly strengthened. The discharge of waste liquid after the permeation detection becomes a problem to be solved urgently.
Patent CN 200810040936.1 proposes an environment-friendly water-based penetrant, in which the solvent and surfactant are also environment-friendly, but the dye is not environment-friendly.
Patent CN 200610022276.5 proposes an antirust water-based penetrant flaw detector, and the dye is also rose red, Congo red and other environmentally-friendly dyes. The penetrant is not completely water-based, and contains 30-50% of penetrating solvent.

In order to solve the technical problems, the invention provides an environment-friendly water-based coloring penetrant which is characterized by comprising the following raw materials in parts by weight:
wherein the environment-friendly dye is one or more of direct fast scarlet 4B, acid red and weak acid scarlet 3 GL.
The invention also provides a preparation method of the environment-friendly water-based coloring penetrant, which is characterized by comprising the following steps: according to the weight portion, 75-95 portions of deionized water are added into a beaker, a stirrer is started to rotate at 500r.min, 2-8 portions of red environment-friendly dye are added while stirring until the red environment-friendly dye is completely dissolved, then 3-9 portions of auxiliary agent and 2-8 portions of antirust agent are sequentially added, and stirring is continued for 30min, so that the environment-friendly water-based coloring penetrant is obtained.
The auxiliary agent is one or more of Tween-80, Tween-60 and SN-4727 wetting agents.
The antirust agent is one or more of triethanolamine borate, organic amine and phosphate.
Compared with the prior art, the invention has the beneficial effects that:
the environment-friendly water-based coloring penetrant replaces the traditional solvent-based penetrant, so that the direct damage to the body of a user is reduced, and the problem of waste water discharge after use is mainly solved. The environment-friendly water-based coloring penetrant does not contain a solvent, is nontoxic and tasteless, and can reach the secondary discharge standard in GB/T8978 + 1996 Integrated wastewater discharge Standard through simple treatment.
