Description
Technical field
The present invention relates to metal oxidation resistance technical field, more particularly to a kind of water base brass antioxidant of addition bamboo vinegar
And preparation method thereof.
Background technology
The alloy that brass is made up of copper and zinc, both with excellent conduction, thermal conductivity and easily processed into type excellent
Point, and with enough mechanical strengths, hardness and chemical resistance, be commonly used for manufacturing valve, water pipe, air-conditioning internal-external machine company
Adapter and radiator etc..But run into acidity, alkaline corrosion medium or be still susceptible in higher temperatures and high humidity environment oxygen
Change corrosion and change colour, have a strong impact on outward appearance and use value while also bringing bad impact to secondary operation.It is domestic at present
The outer handling process to copper and its anti-oxidant discoloration of alloy surface mainly has：It is inorganic passivation technique for filming, organic inhibition technology, dilute
Native addition method, self-assembling technique and resinous coat technology etc., wherein most economical, easy method is passivated in brass surfaces
Process.Most ripe method is that using bichromate Passivation Treatment, but the method is in process of production and the sexavalence that remains in waste liquid
Chromium is noxious material, and many countries have prohibitted the use of bichromate Passivation Treatment, therefore, document《Brass surfaces richness phytic acid is blunt
Change technical study》Have for brass surfaces antirust with the passivating solution that phytic acid, hydrogen peroxide, polyethylene glycol etc. are prepared as primary raw material
Important realistic meaning.
Process is passivated to cold rolling HAl72-2.5-1 brass strips using passivating solution in document, is as a result shown, rich phytic acid
The optimum process condition of passivating film is：Passivation temperature scope is 35～40 DEG C, and pH value is 2.5, and passivation time is 60s；SEM microcosmic
Pattern shows that film surface is smooth, compact structure；Zero-G test result shows can be to alloy material using rich phytic acid Passivation Treatment
Play a very good protection；Show that the sample ratio processed using rich phytic acid adopts bichromate through the saline fog method test of 12h
The sample of process has in more preferable anti-tarnishing ability and rich phytic acid passivating solution without chromium, and pollution of chromium will not be produced in waste liquid.
But the phytic acid film in document, under the heavier environment of humidity, because damp moisture resistance is not good, storage time is short, coating
When brass surfaces carry out secondary operation, resistance to elevated temperatures is limited, in welding process, it is impossible to keep for a long time and multiple
High temperature impact；Secondly in document also there is short anti oxidation time, environmentally friendly bad adaptability, single function, heat surely in obtained passivator
The problems such as qualitative difference, weatherability difference and sun-proof ultraviolet radiation preventing difference, thus limit the lifting of overall performance and apply model
Enclose, it is necessary to improve existing production technology and formula, prepare the brass table with the function such as anti-corrosion, anti-oxidant, wear-resisting, sun-proof
Face process antioxidant.
