Problems solved by technology

The content of aromatic hydrocarbons in kerosene is relatively high, and the volatilization of kerosene during processing is harmful to operators and the environment; at the same time, simply using kerosene or kerosene mixed with mechanical oil as a cooling medium will cause insufficient lubrication performance during processing, thereby reducing workpiece processing. Precision, so that the surface roughness of the workpiece does not meet the standard
In addition, functional additives containing halogen, especially chlorine-based additives, not only cannot provide the effective anti-rust and anti-corrosion performance requirements of the workpiece between processes, but will cause the color of the processed end surface of the workpiece to be blackened and corroded, followed by short-chain (C10-13) Chlorine-based additives and medium-chain (C14-C17) also do not comply with EU regulations "Registration, Evaluation, Authorization and Restriction of Chemicals" REACH certification, unable to meet customer requirements

Abstract

The invention belongs to the technical field of grinding machining oil and relates to gear precision grinding oil and a preparation method thereof. The gear precision grinding machining oil comprises the following components of: secondary hydrogenation paraffin-based mineral oil, pentaerythritol oleate, high-base-number calcium sulfonate, sulfurized fatty acid ester, high-molecular polyisobutene and an antioxidant. The preparation method of the gear precision grinding machining oil comprises the following steps of: putting secondary hydrogenation paraffin-based mineral oil and an antioxidant into a container, heating the materials to 40-50 DEG C, and stirring the materials until the materials is transparent; stopping heating, adding sulfurized fatty acid ester and high-molecular polyisobutene into the container, and performing stirring until the mixture is transparent; adding pentaerythritol oleate and high-base-number calcium sulfonate into the container, and performing stirring until the mixture is transparent; and filtering the liquid in the container, and taking filtrate to obtain the gear precision grinding machining oil. The gear precision grinding machining oil is small in harm to the environment and human bodies, good in lubricating performance, high in rust resistance, corrosion resistance and the like, and capable of reducing the machining precision of workpieces.

Description

technical field [0001] The invention relates to the technical field of grinding oil, in particular to gear precision grinding oil and a preparation method thereof. Background technique [0002] In the process of gear processing, grinding is the last process. Due to the high requirements on the surface quality of the workpiece, oil-based grinding oil is usually used. In order to meet the requirements of lubrication and cooling conditions in gear grinding process, most oil-based grinding oils in the industry usually choose kerosene or a mixture of kerosene and mechanical oil as a carrier compounded with halogen-containing functional additives. The aromatic hydrocarbon content of kerosene is high, and the volatilization of kerosene during processing is more harmful to operators and the environment; at the same time, simply using kerosene or kerosene mixed with mechanical oil as a cooling medium will cause insufficient lubrication performance during processing, thereby reducing ...
