Description

A kind of post processing metal antirusting agent simply and easily

Technical field

The present invention relates to metal conditioner technical field, particularly relate to a kind of post processing metal rust preventing simply and easily Agent.

Background technology

According to statistics, have gross weight the most every year and be equivalent to the steel product of metal annual production 10-20% due to burn into The reasons such as corrosion cause and can not use, and take various rust-proofing method to avoid corrosion for these people, reduce loss.Anti- The kind of rust agent is varied, and its Sodium Nitrite is favored and extensive because of its high rust resistance and cheap enjoying always Use, but the material that there is strong oncogene because of other, therefore in the eighties in 20th century, the most just carry out substantial amounts of grinding Send out work, be prepared for multiple with alkyl, alkoxyl, halogeno-group, naphthoic acid class and derivant thereof, nitrobenzoyl acids and boric acid Ester, borate and molybdate etc. are that main material is to replace the new type water-solubility antirust agent of sodium nitrite.Although these are novel anti- Rust agent relatively sodium nitrite more safe and reasonable, but during its film forming uses, there is more complicated striping process and ask Topic, is typically employed to aqueous alkali and processes, or process with the physical method such as bamboo knife and scraping blade, and such process not only can not eliminate Film, it is also possible to damage metal surface, goes back work consuming time-consuming increase cost.Therefore along with the development of antirust technology, people couple The application of antirust solution and film forming thereof requires also to gradually step up, and occurs in that novel rust-preventing film, strippable property rust-preventing film.

Guo Jun proposes by adding in polyvinyl alcohol in " development of the peelable rust-preventing film of PVA water soluble polymer " literary composition Enter antirust agent and other additives, place it in beaker is heated in the thermostat water bath that temperature is 99 DEG C the most molten Solving, recycling coating the tape casting is coated uniformly on metal surface, drying and forming-film, measures the performance of film, experimental result surface There is good rust-preventing characteristic, in the cold water below 40 DEG C, the most completely insoluble in water, but it is placed in the hot water of more than 40 DEG C In, film can gradually deliquescing thinning, last all dissolve, so limiting use region.The present invention is directed to this shortcoming to poly-second Enol membrane modifying improves the performances such as its water-fast, heat-resisting, oil resistant so that it is disclosure satisfy that the demand of multiple fields, makes to reach more preferable Rust-proof effect and corrosion protection period.

Summary of the invention

The object of the invention is contemplated to make up the defect of prior art, it is provided that a kind of post processing metal rust preventing simply and easily Agent.

The present invention is achieved by the following technical solutions:

A kind of post processing metal antirusting agent simply and easily, is made up of the raw material of following weight portion: cyanuric acid zinc 1.2- 1.5, ethylene glycol monobutyl ether 2.3-3, polyvinyl alcohol 40-50, Polyethylene Glycol 12-15, emulsifying agent op100.4-0.6, glycerol 0.3-0.5, triethanolamine 0.6-0.8, BTA 6-8, sodium benzoate 6-7, sodium lauryl sulphate 2-3, butanedial 0.4-0.6, nano-cellulose 4-5, white carbon black 2.3-2.7, concentrated sulphuric acid 9-11, polyetheramine 3.6-4, deionized water are appropriate.

Described a kind of post processing metal antirusting agent simply and easily, is made up of step in detail below:

(1) being placed in by white carbon black in the solution that concentrated sulphuric acid and concentrated nitric acid are mixed homogeneously according to volume ratio 3:1, magnetic agitation 3h is to white carbon black Being completely dispersed, liter high-temperature, to ultrasonic 24h when 70 DEG C to the most oxidized, filters, washs, dries to obtain oxidized black；

(2) product prepared by step (1) and polyetheramine respectively with deionized water dilution make 1Wt% oxidized black dispersion liquid and Concentration is the polyether amine solution of 10Wt%, polyether amine solution is slowly dropped in oxidized black dispersion liquid, and magnetic agitation 48h is extremely React completely, be subsequently placed in baking oven dry for standby at 60 DEG C；

(3) it is configured to 8Wt% solution under polyvinyl alcohol deionized water being heated when temperature is 95 DEG C and stirred, treats the most molten The product mixing prepared with step (2) after solution, is cooled to 30 DEG C after ultrasonic agitation is uniform, adds butanedial and appropriate concentrated sulphuric acid, Under agitation making it fully react, reaction adds remaining leftover materials, ultrasonic disperse in addition to nano-cellulose after terminating；

(4) the deionized water dissolving ultrasonic disperse of nano-cellulose 2-3 times amount is made suspension, ultrasonic disperse uniformly after and Product mixing prepared by step (3), ultrasonic disperse after stirring, standing and defoaming under room temperature, then product is sprayed on metal Surface of the work, drying and forming-film.

The invention have the advantage that the present invention can be decomposed by the microorganisms according to polyvinyl alcohol, environment is not injured, be a kind of Environmental friendliness shaped material, owing to substantial amounts of hydroxyl is contained on surface, the water absorbing capacity causing thin film is strong, and aqueous solution is good, has after film forming There are strippable property and the plasticity of excellence, according to chemical constitution and the character of polyvinyl alcohol itself, select butanedial that it is cross-linked Modification, improves anti-swelling, seepage slope and the hot strength of polyvinyl alcohol film, utilizes the nano effect of nano-cellulose, high The characteristic such as mechanical strength, strongly hydrophilic, improves the property such as the mechanical strength of polyvinyl alcohol film, heat stability and reduction elongation at break Can, also white carbon black oxidation processes is improved its specific surface area, and utilizes polyethex amine modification white carbon black, improve it and divide in polyvinyl alcohol Dissipate property, effectively raise the ageing resistance of polyvinyl alcohol film, thermostability and anti-wear performance, increase the service life, system of the present invention Standby metal antirusting agent has the performances such as good antirust, anticorrosion, easy to use, it is possible to thin surface of workpiece formation one layer Film, the later stage need not easily remove, easy to use, is worthy to be popularized.
