Abstract
The invention discloses an environmentally-friendly barium-free thixotropic antirust oil, which is characterized by comprising the following components in percentage by weight: antirusting agent 4.0-25.0, thixotropic agent 0.1-5.0, antioxidant 0.1-3.0 and base oil 72.0-94.0. The preparation method of the environmentally-friendly barium-free thixotropic antirust oil comprises: firstly, adding the base oil into a reaction kettle, stirring the base oil, heating the base oil to 110 to 120 DEG C, adding the antirusting agent, stirring the mixture for continuous dehydration for 1 hour, and cooling the mixture to 50 to 60 DEG C; and secondly, adding the antioxidant, stirring the mixture for 3 hours at a constant temperature of 50 to 60 DEG C, adding the thixotropic agent, stirring the mixture for 1 hour at 50 to 60 DEG C, cooling the resulting product to 40 DEG C, filtering the resulting product and discharging the resulting product. For obtaining antirust oil films that are insusceptible to flow and free from heavy metal barium, the antirust oil selects a proper barium-free corrosion inhibiter to ensure excellent antirust performance besides the thixotropic agent added for quickly forming stable oil films of antirust oil.
Description
Technical field
The present invention relates to a kind of slushing oil that is used for steel corrosion protection, particularly relate to a kind of have thixotropic property and the slushing oil of baric element not, belong to field of metal surface treatment technology with Environmental Safety property.
Background technology
Slushing oil since have effective, easy to use, with low cost, be easy to constructing operation easy be easy to advantage such as removal, widespread use at home and abroad.Because the baric inhibiter is (like barium mahogany sulfonate; Dinonyl naphthalene sulfonate barium) has outstanding rustless property; Therefore in existing slushing oil, basically all classify the baric inhibiter as preferred ingredient; For example, publication number is the Chinese invention patent application " a kind of electrostatic painting anticorrosive oil " that the Chinese invention patent application " a kind of preparation method of slushing oil " of CN1629264, Chinese invention patent application " method of manufacture of long-acting antirust oil " that publication number is CN101144046 and publication number are CN101016497.And according to the data record, the compound of barium can cause brain and Leptomeningeal inflammatory disease thereof, and acute poisoning can cause that cessation of growth cessation, white corpuscle and RBC number reduce and content of hemoglobin reduces, but the causing death that seriously poisons.The toxicity of barium salt is by its solubleness decision, and permanent white is actual to be nontoxic, but bariumchloride, nitrate of baryta, barium chlorate, barium acetate, barium carbonate and barium sulphide are hypertoxic.The used oil soluble barium salt of slushing oil is an organic cpds, itself is nontoxic, but it is scattered in the physical environment, can resolve into the soluble barium salt, generates toxic substance.Therefore, the slushing oil that contains the barium element all exists serious harm to environment and human body.Developed country just progressively substitutes, and the strict restriction of American-European countries is used.
In addition, in slushing oil, lubricating type slushing oil accounts for very big proportion.It has safety (flash-point high), be easy to construction, film forming has from renaturation, advantage such as removal easily.But,, cause waste, the pollution construction environment of oil plant so the shortcoming of easy trickling is arranged because its formation is oil film.
Summary of the invention
The objective of the invention is to overcome the above-mentioned deficiency that prior art exists; Improve through research; Provide a kind of environmentally-friendly barium-free thixotropic antirust oil, in order to make the slushing oil oil film be difficult for trickling and not contain heavy metal barium, the present invention removes the adding thixotropic agent makes it form stable oil film fast; Also selecting suitable no barium inhibiter to guarantee good rustless property, is a kind of high-performance special environmental protection and safety type slushing oil that has high technology content and be different from existing slushing oil.
The technical scheme that the present invention provides is: this environmentally-friendly barium-free thixotropic antirust oil, be characterized in its component by weight percentage ratio be:
A. rust-preventive agent 4.0～25.0,
