Description

A kind of high temperature resistant lithotrite surface process water-based antirust adding nano aluminium oxide And preparation method thereof

Technical field

The present invention relates to antirust agent technical field, particularly relate to a kind of high temperature resistant lithotrite surface adding nano aluminium oxide Process water-based antirust and preparation method thereof.

Background technology

Metal erosion can result in the maintenance cost of machinery equipment to be increased, and changes the most in advance, and the corrosion of metal parts is then Reduce the accuracy and sensitivity of equipment, affect the use of equipment, even cause scrapping of equipment.For lithotrite, its The corrosion of non-Painted metal surfaces and metallic element is the most common during storing, using, so must take corresponding Safeguard procedures.For a long time, for reducing the serious corrosion of lithotrite equipment, extension device and parts seal the cycle up for safekeeping, adopt By various methods, antirust agent is exactly one of method therein.

Antirust agent is the synthesis penetrating agent of a kind of super grade high efficiency, it can strongly penetrate into rust, erosion, in greasy dirt thus Easily dispose the rusty stain on screw, nut and erosion, there is infiltration rust cleaning, loosen lubrication, resistance burn into protection metal Etc. performance, and can form and store one layer of lubricating film on parts surface, dampness and other chemical analysis many can be suppressed to make The corrosion become.For avoiding because production and environmental problem, the rust prevention during manufacture of current iron and steel that difficulty causes greatly removed by antirust oil Use water-based antirust more.Industrial widely used water-based antirust usually contains nitrite, phosphate or chromate, this Class antirust agent toxicity is relatively strong, and discharge of wastewater easily causes body eutrophication, uses and discharges the most severely limited.Environment-friendly type The development of water-based antirust is by domestic and international extensive concern.

With phytic acid, poly-aspartate as main component in " development of a kind of nontoxic water-based antirust and performance thereof " literary composition, add Add sodium molybdate and sodium benzoate as auxiliary agent, filter out Polyethylene Glycol and polyvinyl alcohol as macromolecule film former, preparation one Novel non-toxic water-based antirust without nitrite, result shows that phytic acid and poly-aspartate have preferable complex role, helps The existence of agent and macromolecule film former can effectively strengthen the corrosion resistance of rust-preventing film, and carries out antirust effect with nitrous acid salt form antirust agent , there is certain gap, but it be without noxious substance, is worth of widely use in fruit contrast.But it is antirust for the tradition of preparation in literary composition For agent, during developing due to it, it is primarily upon the performance of its rustless property, often ignores environmental protection adaptability, multi-functional And the serviceability under extreme condition, generally there are poor heat stability, weatherability difference and sun-proof ultraviolet radiation preventing difference etc. Problem, thus limit the lifting of antirust agent overall performance, also limit the range of application of antirust agent.

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 add the high temperature resistant broken of nano aluminium oxide Stone machine surface process water-based antirust and preparation method thereof.

The present invention is achieved by the following technical solutions:

A kind of high temperature resistant lithotrite surface process water-based antirust adding nano aluminium oxide, by the raw material system of following weight portion Become: phytic acid 36-37, poly-aspartate 7-9, waste polystyrene foam plastic 9-10, sodium tungstate 2-3, triethanolamine oleate 3.3- 3.5, urea propyl-triethoxysilicane 1.2-1.4, nano aluminium oxide 2.7-2.9, limonene 0.9-1.3, Tissuemat E 3-5, poly- Ethylene glycol 4.2-4.8, polyvinyl alcohol 5.2-5.8, deionized water surplus.

The manufacture method of described a kind of high temperature resistant lithotrite surface process water-based antirust adding nano aluminium oxide, Comprise the following steps:

(1) waste polystyrene foam plastic cleaned, dry, pulverize, join in the dehydrated alcohol of gross weight 1.5-2 times, limit Edged stirs so that it is be completely dissolved, and adds Tissuemat E and is sufficiently stirred for making oil phase liquid, puts into constant temperature in 40-50 DEG C of water-bath and fill Divide and dissolve 1-2 hour, be warming up to 55-65 DEG C of quick stirring 20-30 minute；

(2) being put into by sodium tungstate and be warming up to 60-80 DEG C of constant temperature stirring 20-30 minute in the deionized water of 2/3 mass, addition is planted Acid, urea propyl-triethoxysilicane ultrasonic disperse 15-20 minute, stand to obtain modified phytic acid；

(3) poly-aspartate, nano aluminium oxide, triethanolamine oleate and balance deionized water are mixed, use high pressure homogenize Machine processes 2-3 hour, is spray-dried to obtain modified polyaspartic acid；

(4) step (2), (3) reaction mass are loaded in the reactor with agitator, control rotating speed 60-80 rev/min, stirring 10-15 minute, add step (1) and 30-40 minute stirring while adding of other residual components, discharging.

The invention have the advantage that the present invention with phytic acid, poly-aspartate as main component, with Polyethylene Glycol and polyvinyl alcohol Forming one layer of fine and close thin film for macromolecule film former in metal surface, adding modified waste polystyrene foam plastic is waterproof helping Agent, add other auxiliary agents simultaneously, the antirust agent favorable rust preventing effect that preferably prepared by formula, and persistent；With prior art phase Than the present invention phytic acid is carried out silane coupler modified after ,-the Si-OH-generated after-the P-OH-of phytate molecule and silane hydrolyzate Reaction generates-P-O-Si-key, the chelate of the hydrogenation of six carbocyclic with chair conformation that can be stable with metal generation, is attached to metal Surface, corrosion resistance strengthens, and the product stability of chelating is splendid, even if the most also can stable existence；Also will be poly- Aspartic acid carries out nano aluminium oxide parcel modification, improves the compounding effect with phytic acid, and heat-resisting quantity strengthens；Raw material of the present invention Wide material sources, preparation method is simple, low production cost, will not produce sewage and destroy water environment.
