Description

A kind of high metal antirusting agent of resistance to hot strippable
Technical field
The present invention relates to metal conditioner technical field, particularly relate to a kind of high metal antirusting agent of resistance to hot strippable.
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% and cause and can not use due to reasons such as burn into corrosions, take various rust-proofing method to avoid corrosion for these people, reduce loss.The kind of antirust agent is varied, its Sodium Nitrite is favored because of its high rust resistance and cheap enjoying always and is widely used, but because other has the material of strong oncogene, therefore in the eighties in 20th century, just carry out substantial amounts of R&D work both at home and abroad, be prepared for the multiple material based on alkyl, alkoxyl, halogeno-group, naphthoic acid class and derivant thereof, nitrobenzoyl acids and borate, borate and molybdate etc. to replace the new type water-solubility antirust agent of sodium nitrite.Although these novel antirust agent relatively sodium nitrite more safe and reasonable, but during its film forming uses, there is more complicated striping and process problem, it is typically employed to aqueous alkali process, or process with the physical method such as bamboo knife and scraping blade, 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, the application of antirust solution and film forming thereof is required also to gradually step up by people, occurs in that novel rust-preventing film, strippable property rust-preventing film.
Guo Jun proposes by adding antirust agent and other additives in polyvinyl alcohol in " development of the peelable rust-preventing film of PVA water soluble polymer " literary composition, place it in beaker and be heated to being completely dissolved in the thermostat water bath that temperature is 99 DEG C, recycling coating the tape casting is coated uniformly on metal surface, drying and forming-film, measure the performance of film, experimental result surface has good rust-preventing characteristic, in 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, film can gradually deliquescing thinning, last all dissolvings, so limiting use region.The present invention is directed to this shortcoming and polyvinyl alcohol membrane modifying is improved the performances such as its water-fast, heat-resisting, oil resistant so that it is disclosure satisfy that the demand of multiple fields, make 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 high metal antirusting agent of resistance to hot strippable.
The present invention is achieved by the following technical solutions:
A kind of high metal antirusting agent of resistance to hot strippable, it is made up of the raw material of following weight portion: methyl-silicone oil 0.3-0.5, polyacrylic acid 0.7-0.9, 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, maleic anhydride 2.1-2.4, calcium phosphate 3.2-3.4, silica gel 2.5-3, triethylene tetramine 0.5-0.7, aluminium oxide 2.8-3.3, calcium phosphate 2.8-3, deionized water is appropriate.
The high metal antirusting agent of resistance to hot strippable of described one, is made up of step in detail below:
(1) methyl-silicone oil, polyacrylic acid and maleic anhydride are stirred at 40-50 DEG C 1-2h, it is stirring evenly and then adding into silica gel and triethylene tetramine, then proceed to liter high-temperature to adding aluminium oxide and calcium phosphate when 55-75 DEG C, at 600-800 DEG C, stir 40-50min, be then added in rubber mill wear into micropowder standby；
(2) it is configured to 8Wt% solution under polyvinyl alcohol deionized water being heated when temperature is 95 DEG C and stirred, the product mixing prepared with step (1) after all dissolving, it is cooled to 30 DEG C after ultrasonic agitation is uniform, add butanedial and appropriate concentrated sulphuric acid, it is under agitation made fully to react, reaction adds remaining leftover materials, ultrasonic disperse in addition to nano-cellulose after terminating；
(3) the deionized water dissolving ultrasonic disperse of nano-cellulose 2-3 times amount is made suspension, ultrasonic disperse uniformly after and the product prepared of step (2) mix, ultrasonic disperse after stirring, standing and defoaming under room temperature, then product is sprayed on surface of workpiece, drying and forming-film.
nullThe invention have the advantage that the present invention can be decomposed by the microorganisms according to polyvinyl alcohol，Environment is not injured，It it is 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，Aqueous solution is good，There is after film forming strippable property and the plasticity of excellence，Chemical constitution according to polyvinyl alcohol itself and character，Butanedial is selected to carry out cross-linking modified to it，Improve the anti-swelling of polyvinyl alcohol film、Seepage slope and hot strength，Utilize the nano effect of nano-cellulose，High mechanical properties、The characteristics such as strongly hydrophilic，Improve the mechanical strength of polyvinyl alcohol film、The performances such as heat stability and reduction elongation at break，Also utilize modifying agent modified to aluminium oxide and calcium phosphate，Make it have outstanding anticorrosion、Antirust and high caking property，Can in poly-vinyl alcohol solution good dispersion，And do not affect filming performance，Improve the toughness of film、Intensity and mechanical performance thereof，Film is made to be not easily broken，Metal antirusting agent prepared by the present invention can form thin film at surface of the work，Waterproof and oilproof、It is not easily broken，Heat-resisting good with ageing-resistant performance，Play good antirust, anti-corrosive effect，Later stage peels off convenient，It is worthy to be popularized.
