[0044] [Examples 1 to 3]

[0045] Add base oil and pour point depressant, heat up to 60°C for heating and stirring. After maintaining for 2 hours, reduce the temperature to 40°C; then add other ingredients and stir for 2 hours until the mixture is completely dissolved and becomes transparent. The composition. The specific components and product performance of the composition are shown in Table 1. Among them, Example 1 and Example 2 are products of lower viscosity grade, and Example 3 is products of higher viscosity grade.

Abstract

The invention relates to a lubricant composition and application thereof. The lubricant composition is prepared from, by weight, 80-98% of mineral oil, 0.5-10.0% of purification dispersant, 0.5-2.0% of extreme pressure agent, 0.1-1.0% of pour point depressant, 0.1-0.5% of phosphorus anti-wear agent, 0.1-0.5% of antioxidant, 0.1-0.5% of metal deactivator, 0.01-0.2% of friction modifier, 0.01-0.1% of antirust agent and 0.001-0.05% of anti-foaming agent. The lubricant composition can be used for lubricating during cold heading forming and machining.

Description

technical field [0001] The invention relates to a lubricating oil composition and its application. Background technique [0002] Cold heading is a forging method that uses a mold to apply external force to the metal at room temperature to form the metal in a predetermined mold. It is usually used to manufacture the heads of screws, bolts, rivets, etc., which can reduce or replace cutting processing. Cold heading processing is mostly carried out on a special cold heading machine. On the cold heading machine, the processes of material cutting, heading, accumulation, forming, chamfering, thread rolling, diameter reduction and edge trimming can be completed in sequence, and continuous and multi-station can be realized. , Automatic production, suitable for mass production of fasteners. [0003] The liquid lubricants commonly used in cold heading processing include mineral oil type and animal and vegetable oil type. Document CN104403738A discloses a cold heading oil technology, ...
