Abstract

The invention relates to the field of lubricating oil compositions, in particular to a high-power heavy punch cylinder lubricating grease composition and a preparation method thereof. The lubricating grease composition comprises base oil and a thickening agent, the thickening agent is prepared from calcium hydroxide, lithium hydroxide, 12-hydroxystearic acid and sebacic acid; wherein the mass ratio of the calcium hydroxide to the lithium hydroxide is 1: (7-9); the mass ratio of the sebacic acid to the 12-hydroxystearic acid is 1: (2-4). The lubricating grease composition disclosed by the invention has good wear resistance and high and low temperature performance, has the characteristics of good oxidation resistance, good wear resistance, good anti-corrosion protection effect and the like, can keep excellent comprehensive performance at the temperature of -15 DEG C to 200 DEG C, and can better meet the lubricating working condition of a high-power heavy punch cylinder.

Description

technical field [0001] The invention relates to the field of lubricating oil compositions, in particular to a high-power weight cylinder lubricating grease composition and a preparation method thereof. Background technique [0002] The electric hammer is an electric rotary hammer drill with a safety clutch attached to a pneumatic hammering mechanism. It uses the principle of piston movement to impact the drill bit with compressed gas to open holes in hard materials such as concrete, bricks, and stones. Among them, the impact movement is formed by the rotation of the motor through the gear to drive the eccentric link mechanism, so that the compressor piston reciprocates in the cylinder liner. When the electric hammer is running, adding grease can reduce the aging wear of the sealing rubber ring of the electric hammer cylinder, improve the protection performance, and at the same time prolong the life cycle of the electric hammer and reduce unnecessary loss. At the same time,...
