[0028] Pump the base oil into the blending kettle, start the agitator and the heating switch, and when the oil is heated to 50°C, add antioxidant, stir thoroughly for more than 30 minutes until completely dissolved, add extreme pressure agent and oily agent, and stir for 30 minutes Then add the corrosion inhibitor and stir for 2 hours until it is completely transparent, and a uniform yellow liquid is obtained. Each component and its content are shown in Table 1, and its corresponding performance indicators are shown in Table 3.

Abstract

The invention relates to a honing lubricating oil composition and application thereof. The honing lubricating oil is prepared from the following components in parts by weight: a) 90-98 parts of base oil, b) 1-4 parts of an extreme pressure agent, c) 2-6 parts of an oily agent, d) 0.1-1 part of antioxidant, and e) 0.1-1 part of corrosion inhibitor. In the honing lubricating oil, the low-viscosity base oil (the viscosity is not larger than 5 mm<2> / s at the temperature of 40 DEG C) is selected, and a tackifier or a viscosity index improver as well as chlorine elements and heavy metal elements badfor the environment is not added, so that the product has excellent cooling performance, settleability, permeability and high extreme pressure lubricity and anti-rust property and anti-corrosion property, and provides good lubrication protection for honing processing of precision parts such as an engine fuel injection pump, a fuel spray nozzle and a plunger and barrel assembly.

Description

technical field [0001] The invention relates to a honing oil composition and its application. Background technique [0002] Honing is a special grinding process and an efficient precision hole processing method, which can not only improve the geometry and surface structure of the hole, but also remove the residual stress generated by drilling, reaming and internal grinding, so It is widely used in batch processing of cylinder holes, connecting rods, hydraulic valve body holes, gear holes and oil pump nozzles. The matching honing oil is used as a lubricating cooling medium, which will greatly affect the honing process effect. For the honing process of small precision parts such as engine fuel injection pump nozzles and plunger couplers, due to the small heat dissipation space and the difficulty in discharging abrasive debris, in order to avoid the generation of built-up edge, honing oil is required to have better cooling and cleaning properties. As well as higher wear reduc...
