Description

The metal surface antirust agent that a kind of cost performance is high
Technical field
The present invention relates to metal conditioner technical field, particularly relate to the metal surface antirust agent that a kind of cost performance is high.
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 the metal surface antirust agent that a kind of cost performance is high.
The present invention is achieved by the following technical solutions:
The metal surface antirust agent that a kind of cost performance is high, it is made up of the raw material of following weight portion: aqueous polyurethane emulsion 3.6-4, chitin 2.8-3.5, 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, calcium carbonate 3.2-3.7, lauric acid 0.7-0.9, silane coupler kh5500.3-0.4, cumyl peroxide 0.2-0.3, montmorillonite 0.6-0.8, deionized water is appropriate.
The metal surface antirust agent that described a kind of cost performance is high, is made up of step in detail below:
(1) by chitin with 3% acetate dissolution, make the chitin acetum of 4-6%, after stirring standby, by calcium carbonate, lauric acid, aqueous polyurethane emulsion and silane coupler kh550 mix, when temperature is 40-50 DEG C with 400-600 rev/min under stir 40-50min, it is then added in standby chitin acetum, it is stirring evenly and then adding into cumyl peroxide, normal-temperature reaction 30-40min, filters, drying, ground 1000-1250 mesh sieve is 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，Modifier modification calcium carbonate is also utilized to make it have excellent hydrophobic、Oil resistant、The performance of the aspects such as antirust and anticorrosion，Do not affect the performance of polyvinyl alcohol itself，And improve toughness and the intensity of film，It is not easily broken，And resistance to water is high，Also reduce the maintenance cost of metallic article，Antirust agent composition and ratio prepared by the present invention are scientific and reasonable，While playing excellent rust inhibition, also accomplished that addition is few，The cost-effective effect with natural resources，Thin film can be formed at surface of workpiece，Strippable property is good，The saving time，It is worthy to be popularized.
