According to the comparison of embodiment and comparative example it is found that being added to the cutting fluid composite to methyl phenylpropyl triazole piperazine Corrosion mitigating effect significantly better than being added to the cutting fluid composite of other Mannich bases and be added to the cutting of benzotriazole Liquid composition.In the case where being equally added to methyl phenylpropyl triazole piperazine, the cutting fluid inhibition effect of diglycolamine is added Cutting fluid of the fruit significantly better than addition triethanolamine.
Specific embodiments of the present invention are described above.It is to be appreciated that the invention is not limited to above-mentioned Particular implementation, those skilled in the art can make various deformations or amendments within the scope of the claims, this not shadow Ring substantive content of the invention.
