Abstract
The invention discloses a kind of preparation methods of cutting fluid nonionic surfactant, specific steps include: copolyreaction: natural rosin and cis-butenedioic anhydride are put into reaction kettle, 150 DEG C at a temperature of so that natural rosin and cis-butenedioic anhydride carry out copolyreaction, obtain copolymer；Neutralization reaction: and then diethanol amine is added into the reaction kettle of obtained copolymer, catalyst, and air draft appropriate is then added, it is kept the temperature after being heated to 140 DEG C, it is made to react 3h, after being then measured value and aqueous solution qualification, cooling is released after being cooled to 80 DEG C, finally obtains finished product.Through the above way, a kind of preparation method of cutting fluid nonionic surfactant of the present invention, the nonionic surfactant and triethanolamine oleate ester coordinative role of this method preparation, significantly reduce the surface tension of cutting fluid, the permeability and mobility of cutting fluid are significantly enhanced, good cleaning performance is made it have.
Description
Technical field
The present invention relates to cutting fluid field more particularly to a kind of preparation methods of cutting fluid nonionic surfactant.
Background technique
Cutting fluid is the important supplementary material of metal cutting process, and the purpose using metalworking fluid is exactly to reduce cutting
Friction between power and cutter and workpiece takes away the heat generated in cutting region in time to reduce cutting temperature, reduces cutter mill
Damage improves tool life, to improve production efficiency, improves workpiece surface roughness, guarantees Workpiece Machining Accuracy, to reach
To economic optimum, being added in the preparation of cutting fluid has nonionic surfactant.
Summary of the invention
The invention mainly solves the technical problem of providing a kind of preparation methods of cutting fluid nonionic surfactant.
In order to solve the above technical problems, one technical scheme adopted by the invention is that: a kind of cutting fluid non-ionic surface
The preparation method of activating agent, specific steps include:
Copolyreaction: natural rosin and cis-butenedioic anhydride are put into reaction kettle, 150 DEG C at a temperature of so that natural rosin and cis-butenedioic anhydride
Copolyreaction is carried out, copolymer is obtained；
Neutralization reaction: and then diethanol amine is added into the reaction kettle of obtained copolymer, catalyst is then added, and appropriate
Air draft is kept the temperature after being heated to 140 DEG C, it is made to react 3h, after being then measured value and aqueous solution qualification, is put after being cooled to 80 DEG C
It cools down out, finally obtains finished product.
In a preferred embodiment of the present invention, the natural rosin is made of the rosin acid of various structures, is specifically included
Rosin acid, dextrorotation rosin acid and left-handed rosin acid.
In a preferred embodiment of the present invention, it when the neutralization reaction, needs to be slowly added to when diethanol amine is added
And it constantly stirs.
The beneficial effects of the present invention are: a kind of preparation method of cutting fluid nonionic surfactant of the present invention, the party
The nonionic surfactant and triethanolamine oleate ester coordinative role of method preparation significantly reduce the surface of cutting fluid
Power, it will be apparent that enhance the permeability and mobility of cutting fluid, make it have good cleaning performance.
Specific embodiment
The preferred embodiments of the present invention will be described in detail below so that advantages and features of the invention can be easier to by
It will be appreciated by those skilled in the art that so as to make a clearer definition of the protection scope of the present invention.
The embodiment of the present invention includes: a kind of preparation method of cutting fluid nonionic surfactant, specific steps include:
Copolyreaction: natural rosin and cis-butenedioic anhydride are put into reaction kettle, 150 DEG C at a temperature of so that natural rosin and cis-butenedioic anhydride
Copolyreaction is carried out, obtains copolymer, the natural rosin is made of the rosin acid of various structures, specifically includes rosin acid, the right side
Rosin acid and left-handed rosin acid are revolved, under conditions of cis-butenedioic anhydride, rosin acid is isomerized to left-handed rosin acid at 150 DEG C, is then
Cis-butenedioic anhydride carries out copolyreaction.
Neutralization reaction: and then diethanol amine is added into the reaction kettle of obtained copolymer, catalyst is then added, and fit
When air draft, kept the temperature after being heated to 140 DEG C, it made to react 3h, be then measured value and aqueous solution it is qualified after, be cooled to 80 DEG C
Cooling is released afterwards, finally obtains finished product.
It when the neutralization reaction, needs to be slowly added to simultaneously constantly stir when diethanol amine is added, makes its contact sufficiently,
It reacts more complete.
Compared with prior art, a kind of preparation method of cutting fluid nonionic surfactant of the present invention, party's legal system
Standby nonionic surfactant and triethanolamine oleate ester coordinative role, significantly reduces the surface tension of cutting fluid, bright
The permeability and mobility of cutting fluid are enhanced aobviously, make it have good cleaning performance.
The above description is only an embodiment of the present invention, is not intended to limit the scope of the invention, all to utilize this hair
Equivalent structure or equivalent flow shift made by bright specification is applied directly or indirectly in other relevant technical fields,
Similarly it is included within the scope of the present invention.
