Abstract

The invention relates to synthetic ester for rolling oil. The synthetic ester comprises tetrahydric acid ester which has a structure as shown in the formula (I), in the formula (I), A is substituted or unsubstitutedalkyl, and at least one of B1, B2, B3 and B4 is a group containing a polyether structure. The polyether structure is introduced in the synthetic ester for the rolling oil, the tetrahydric acid ester has properties of a nonionic emulsifier, and the synthetic ester has good permeability, self-emulsifying performance and dispersing performance. When the synthetic ester is used for the rolling oil, cleaning of a rolling machine and a plate surface is facilitated by the permeability and the dispersing performance; in a high-temperature rolling process, stability of emulsion of the rolling oil can be maintained by the self-emulsifying performance, concentration response is good, oil slick of emulsion is less, the service life of the emulsion is prolonged, oil consumption is low, and therefore, the synthetic ester is easy to manage. The synthetic ester is the tetrahydric acid ester, has high-temperature stability, cannot be decomposed easily, cannot produce a large amount of smoke, and is environmentally friendly.

Description

technical field [0001] The invention belongs to the field of rolling oil, and particularly relates to a synthetic ester for rolling oil, silicon steel rolling oil containing the same, and use thereof. Background technique [0002] Silicon steel is a ferrosilicon soft magnetic alloy with extremely low carbon content, generally containing 0.5 to 4.5% of silicon. Adding silicon can improve the resistivity and maximum magnetic permeability of iron, reduce the coercivity, core loss (iron loss) and magnetic aging, mainly used to make the iron core of various transformers, motors and generators, is the electronic, power It is an indispensable important soft magnetic alloy material in the military industry. With the increase of silicon content, the yield strength and tensile strength of silicon steel increase significantly, the elongation decreases significantly, and the hardness increases rapidly. High-grade silicon steel has high silicon content, high deformation resistance, hig...
