Description
Technical field
The present invention relates to metal oxidation resistance technical field, more particularly to a kind of water base brass of high corrosion-resistant for adding Ludox
Antioxidant and preparation method thereof.
Background technology
The alloy that brass is made up of copper and zinc, both with excellent conductive, thermal conductivity and easily processed into type excellent
Point, and with enough mechanical strengths, hardness and chemical resistance, be commonly used for manufacture valve, water pipe, air-conditioning internal-external machine and connect
Adapter and radiator etc..But run into acid, alkaline corrosion medium or in higher temperatures and high humidity environment be still susceptible to oxygen
Change corrosion and change colour, have a strong impact on outward appearance and use value while also bringing bad influence 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
Treatment.Most ripe method is to use bichromate Passivation Treatment, but the sexavalence that the method is remained in process of production and 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》With phytic acid, hydrogen peroxide, polyethylene glycol etc. for passivating solution prepared by primary raw material has for brass surfaces antirust
Important realistic meaning.
Treatment 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 is 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；Bichromate is used using the sample ratio that rich phytic acid is processed by the saline fog method experiment display of 12h
The sample for the treatment of is free of chromium in having more preferable anti-tarnishing ability and rich phytic acid passivating solution, 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, unitary 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 treatment antioxidant.
The content of the invention
The object of the invention is exactly to make up the defect of prior art, there is provided a kind of high corrosion-resistant of addition Ludox is water base
Brass antioxidant and preparation method thereof.
The present invention is achieved by the following technical solutions：

Alkane 2.3-2.5, appropriate deionized water.
A kind of preparation method of the water base brass antioxidant of high corrosion-resistant of described addition Ludox, including following step
Suddenly：
（1）Fed Protein Powder of Pea Insteal is mixed the suspension for being configured to that mass percent concentration is 5-10% in deionized water, is put into
In 40-60 DEG C of water-bath, add Ludox ultrasonic disperse to grind 6-12 hours, add 1-hydroxy ethylidene-1,1-diphosphonic acid ultrasound wave irradiation reaction 2-
8 hours, room temperature is cooled to, is spray-dried to obtain modified pea proteins powder；
（2）Triethoxy octyl group silane and deionized water are pressed 1：3 mass ratio is warming up to 80- after mixing is stirred at room temperature
100 DEG C, add Tween 80, citronella oil ultrasonic disperse to grind 5-7 hours, be cooled to 45-55 DEG C and add reaction of phytic acid 1-2 hours,
Must be modified phytic acid；
（3）By step（1）Obtained modified pea proteins powder grinding distribution is in step（2）In the obtained modified phytic acid aqueous solution,
Being warming up to 70-80 DEG C adds alkanolamide to react 4-6 hours, cooling；
（4）By step（3）Material is put into reactor, adds sodium molybdate and other residual components to stir and evenly mix, and adds water to 1L, in
40-50 DEG C is stirred 20-60 minutes, discharging.
It is an advantage of the invention that：The present invention with phytic acid, hydrogen peroxide as main component, due to there is 24 oxygen originals in phytate molecule
Son, 12 hydroxyls and 6 are phosphate-based, and these atoms or group can form complex compound with metallic atom and metal ion, will plant
Acid carry out it is silane coupler modified after, on the one hand can be anti-by hydrogen bond or dehydration between unreacted phosphorus hydroxyl in passivating process
Should, connection forms spatial networks phytic acid (salt) passivating film of high crosslink density, on the other hand can with silane hydrolyzate after generate-
Si-OH- reaction generation-P-O-Si- keys, can be attached to one layer of metal surface formation colourless with the chelate of metal generation stabilization
Homogeneous, the non-microcracked protective film of transparent, surfacing, thickness densification effectively prevents corrosive medium from penetrating into metal surface,
So as to slow down corrosion of metal, by Fed Protein Powder of Pea Insteal through Ludox, 1-hydroxy ethylidene-1,1-diphosphonic acid is modified is added in raw material, carry
Its viscosity in water high, then compatibility other antioxidants obtained in effective auxiliary agent can be directly dissolved in water, easy to operate, no
Must special installation, product is coated in that the good difficult for drop-off, corrosion resistance of brass surfaces adhesive force is strong and the time is long, anti-oxidant is preapred for an unfavorable turn of events
Color ability is excellent, and antioxidant of the invention does not contain Cr VI, the pollution of production process non-hexavalent chromium.
