During the assembly of the hydraulic support, the production or maintenance manufacturer may wear the sealing element if proper grease is not applied in time. The tiny impurities generated after abrasion play a grinding role between the sealing elements along with the flowing of working media, so that the abrasion of the elements is accelerated, the sealing plane is damaged, the hydraulic valve loses the sealing performance, and even the whole valve body is damaged and fails, and the service life of the hydraulic support is influenced. In addition, in the installation process of the hydraulic support body, consumed lubricating grease is coated to assemble parts such as the oil cylinder, the piston and the sealing element, and lubrication and sealing among the parts are realized.
At present, the calcium-based lubricating grease butter is widely used by coal mine units in China for assembling a hydraulic support body and a hydraulic control system. Through the information that uses, observes and a ray of staff provided, discover that hydraulic support accomplishes half a year at the new installation, the butter can drop and ooze, solidifies even to solid particle, causes the work medium muddy inside the support, and the valve member wearing and tearing causes accidents such as jam, has reduced the life of equipment. In addition to "grease", other conventional solid lubricating materials also suffer from the same problem, which may form a poorly soluble solid clogging system after being dropped in water, or be incompatible with the hydraulic system transmission medium in operation, causing deterioration of the transmission medium.
Disclosure of Invention
The invention aims to prepare water-soluble hydraulic support assembly lubricating grease which is applied to the assembly and installation processes of a hydraulic support body and a hydraulic control system, and after the assembly and installation are finished, the water-soluble hydraulic support assembly lubricating grease can be uniformly dispersed in water-based liquid, so that the hydraulic system cannot be blocked in the operation of a hydraulic support; can have better compatibility with the transmission medium and can not cause the failure of the hydraulic transmission medium.
The water-soluble hydraulic support assembly lubricating grease is characterized by being prepared by taking oleic acid, sebacic acid, triethanolamine, polyoxyethylene sorbitan monooleate, sodium dodecyl benzene sulfonate, sodium tetraborate and ethylenediamine as raw materials and reacting at a certain temperature and normal pressure, wherein the main raw materials and the dosage proportion are as follows (wt%):
