Description
Technical field
The present invention relates to field of metal surface treatment technology, and in particular to a kind of environment-protective water displacing type rust preventive oil and its preparation
Technology.
Background technique
In metal-working industry, due to laying in or in a short time can not carry out the processing of next process,
It places it in warehouse and saves, in library procedure, metal can be because of the different environment of surrounding, and more or less is corroded.
It will affect the characteristic of itself after corrosion and interfere its following process or use, the loss as caused by metal erosion every year is
Huge, the meaning of protection is particularly important.Especially in the cutting process, cutting and water base clear is being carried out using aqueous cutting fluid
It, can be certain water stain in workpiece surface residual after lotion is cleaned.If spraying the antirust oil of not dehydrating function, the water on surface
Stain cannot be removed effectively, it is easy to cause the corrosion of workpiece.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of barium-free, environment-friendly type water displacing type rust preventive oils.
A kind of environment-protective water displacing type rust preventive oil composition, is grouped as by the group of following mass fraction:
75-90 parts of base oil;5-15 parts of antirust agent;2-5 parts of dehydrating agent;1-5 parts of adjuvant.
Further, the antirust agent is sulfanilic acid.
The sulfanilic acid synthesizes in accordance with the following methods:
Petroleum sodium sulfonate and alkylamine are pressed into content molar ratio for 1:1.5~1:2.0 addition reaction kettle, in extraction kettle
It obtains air to air pressure and is less than or equal to 100Pa, being filled with nitrogen to air pressure is 3~3.5MPa;
Constant temperature stirs 120-140min after being heated to 110-120 DEG C, and extraction nitrogen to air pressure is less than 300Pa, is heated to
130-140 DEG C, constant temperature stirs 60-80min, is evaporated under reduced pressure out excessive alkylamine;The sulfanilic acid that can be produced after cooling.
Further, the alkylamine is monoamine base.
Further, carbon atom is 14-20 in the alkylamine.
Further, the adjuvant is basic aluminium stearate.
Further, the dehydrating agent is at least one of oleic acid and fatty acid polyethylene ether.
Base oil of the invention can select the common white mineral oil of the art or solvent that the present invention can be achieved, excellent
Select at least one of D60, D70, D80 and D100 in solvent naphtha.
Environment-protective water displacing type rust preventive oil of the invention can be prepared by the stirring accord method of this field routine:
Base oil investment blending kettle is heated to 35-50 DEG C and is stirred, antirust agent, adjuvant and dehydration are sequentially added
Agent stirs 1-2 hours under the conditions of 35-45 DEG C of constant temperature to get the environment-protective water displacing type rust preventive oil.
The invention has the following beneficial effects:
The present invention has excellent rust-preventing characteristic and water substituting, can meet American-European environmental requirement without heavy metal, solve
Export the antirust, anti-corrosive problem of American-European metal processing piece;Using homemade antirust agent, not only favorable rust preventing effect, but also can replace
For similar high-end product, purchase cost is significantly reduced for client.
