High-temperature-resistant precipitation antagonist for hydraulic oil

Abstract

The invention relates to the technical field of hydraulic oil, in particular to a high-temperature-resistant precipitation antagonist for hydraulic oil. The precipitation antagonist is prepared from the following components in percentage by weight: 70 to 80 percent of base oil, 2 to 6 percent of 6-butylated hydroxytoluene, 2 to 5 percent of zinc dialkyl dithiophosphate, 2 to 10 percent of anticoagulant, 1 to 3 percent of dispersing agent, 1 to 3 percent of accelerant, 1 to 3 percent of PH regulator, 2 to 5 percent of stabilizer, 3 to 8 percent of water retention agent, 2 to 5 percent of defoaming agent and 1 to 2 percent of clarifying agent. The main shaft drives the pushing mechanism to rotate, so that the roller rolls along the disc, and the roller is in intermittent rolling fit with the curved surface block. When the rollers roll along the curved surface blocks, the rollers roll to drive the limiting rods to move downwards, and the limiting rods push the walking plates to slide downwards along the sliding grooves; and meanwhile, the walking plate extrudes the shaking spring, and the walking plate is pushed to slide upwards under the elastic action of the shaking spring; the operations are repeated so as to make the walking plate to shake vertically, so that the intermediate product C is filtered and purified, and the precipitate antagonist is prepared.

Description

Technical field [0001] The present invention relates to the technical field of hydraulic oil, particularly precipitated antagonist is a hydraulic oil temperature. Background technique [0002] Hydraulic oil is the use of hydraulic fluid pressure medium can be used in hydraulic systems, hydraulic energy transfer system plays the role of anti-wear, lubrication systems, corrosion, rust and cooling. For the hydraulic oil, a first hydraulic device should meet at operating temperature and the lower temperature requirements for starting the liquid viscosity, the viscosity of lubricating oil changes in the operation of the hydraulic transmission efficiency and transmission accuracy is directly related, also called viscosity-temperature properties of the oil shear stability and should meet different needs for the proposed use. Therefore very important to ensure the stability of the hydraulic oil. [0003] Antagonist currently on the market are used in the solid particulate or powder, when...

AI Technical Summary

Problems solved by technology

[0003] At present, the antagonists used in the market are all solid particles or powders. In actual use, they need to be stirred and melted, and are prone to precipitation. These sediments will seriously affect the quality of hydraulic oil and affect the use of hydraulic oil.
