Abstract
The invention discloses degradable hydraulic oil which includes, by weight, 20-30 parts of dibutyltin dilaurate, 30-40 parts of ethylene glycol adipate mixed with polyester diol, 10-20 parts of tert-butyl alcohol, 8-16 parts of triethylene tetramine, 3-9 parts of polyacrylamide and 2-6 parts of sodium dodecyl benzene sulfonate. The degradable hydraulic oil is environmental-friendly, can be directly discharged to environment and can be auto-degraded after a certain time. By means of the triethylene tetramine and polyacrylamide, the environmental-friendly hydraulic oil composition is excellent in anti-abrasion performance, anti-oxidizing performance, hydrolysis stability, anti-rust performance and bio-degradability, wherein the overall performance can satisfy an index requirement.
Description
Technical field
The present invention relates to hydraulic efficiency oil, particularly relate to degradable hydraulic efficiency oil and preparation method thereof.
Background technology
Hydraulic efficiency oil be exactly utilize liquid pressure can the pressure medium that uses of hydraulic efficiency system, in hydraulic efficiency system, play the effects such as transmission ofenergy, wear-resistant, system lubrication, anticorrosion, antirust, cooling.For hydraulic efficiency oil, first should meet hydraulic efficiency plant at the working temperature with requirement to liquid viscosity under start-up temperature, because oil body change is directly relevant with hydraulic operation, transfer efficiency and transmitting accuracy, the various demands also requiring oily viscosity temperature characteristic and shear stability should meet different purposes to propose.Hydraulic efficiency oil of a great variety, sorting technique is different, for a long time, is accustomed to classifying with purposes, also with good grounds oil product type, chemical composition or flammability class.What these sorting techniques only reflected oil product earns note, but lacks systematicness, is also difficult to understand the mutual relationship between oil product and development.Biological degradation hydraulic efficiency oil is to adapt to environmental requirement, control environment pollute and exploitation.Mainly contain plant base oil and synthetic vinegar, vegetables oil is owing to having natural biodegradability, outstanding lubricity and viscosity temperature characteristic, and aboundresources, relative low price, is the main development direction of environment-protective lubricant oil.This hydraulic efficiency oil does not have formal product hydraulic efficiency oil in China.
Summary of the invention
The technical problem to be solved in the present invention is that the hydraulic efficiency oil of existing domestic use can not be degraded, and pollute comparatively large, resource utilization is not high, provides a kind of degradable hydraulic efficiency oil and preparation method thereof for this reason.
Technical scheme of the present invention is: degradable hydraulic efficiency oil, and it comprises with parts by weight: the dibutyl tin laurate of 20-30 part, the glycol adipate of 30-40 part mix the Sodium dodecylbenzene sulfonate of polyester glycol, the trimethyl carbinol of 10-20 part, the triethylene tetramine of 8-16 part, the polyacrylamide of 3-9 part and 2-6 part.
The preparation method of above-mentioned degradable hydraulic efficiency oil, it comprises the following steps: (1), the trimethyl carbinol glycol adipate of the dibutyl tin laurate of 20-30 part, 30-40 part being mixed polyester glycol and 10-20 part are mixed and heated to 80-90 DEG C, add the triethylene tetramine of 8-16 part and the polyacrylamide of 3-9 part, be warming up to 100-120 DEG C and stir 5-10min, the Sodium dodecylbenzene sulfonate adding 2-6 part continues to be stirred to evenly, filters and obtains finished product.
The invention has the beneficial effects as follows that obtained hydraulic efficiency oil is environmentally friendly, directly can enter the external world, can degrade voluntarily after a while, and the triethylene tetramine added, polyacrylamide make this Environmental-friendhydraulic hydraulic oil composition have the performances such as good wear resistance, antioxidant property, hydrolysis stability, rustless property and biological degradability, its over-all properties can meet index request.
