Description

A kind of antibacterial, worm-expelling type seeder surface process water-based antirust and preparation method thereof

Technical field

The present invention relates to antirust agent technical field, particularly relate to a kind of antibacterial, worm-expelling type seeder surface and process with water base anti- Rust agent 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 agricultural seeding machine Speech, the corrosion of its non-Painted metal surfaces and metallic element is the most common, so must take during storing, using Corresponding safeguard procedures.For a long time, for reducing sealing up for safekeeping of the serious corrosion of agricultural seeding machine equipment, extension device and parts In the cycle, have employed various method, 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 antibacterial, worm-expelling type seeder surface processes With water-based antirust and preparation method thereof.

The present invention is achieved by the following technical solutions:

A kind of antibacterial, worm-expelling type seeder surface process water-based antirust, is prepared by the raw materials in: phytic acid 34- 36, poly-aspartate 7-8, waste polystyrene foam plastic 9-11, Fructus Zanthoxyli oil 4-6, diethylenetriamine 2-3, myristic acid 1- 2, γ-mercaptopropyl trimethoxysilane 1.5-1.8, sodium alginate 0.7-0.9, Pericarpium Citri tangerinae extract 6-7, nano silicon 2.2- 2.4, Polyethylene Glycol 3.2-3.5, polyvinyl alcohol 4.2-4.5, deionized water surplus.

The manufacture method of described a kind of antibacterial, worm-expelling type seeder surface process water-based antirust, including following step Rapid:

(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 addition Fructus Zanthoxyli oil, myristic acid are sufficiently stirred for making oil phase liquid, put into 40-50 DEG C of water-bath Middle constant temperature fully dissolves 1-2 hour, is warming up to 55-65 DEG C of quick stirring and obtains for 20-30 minute；

(2) Pericarpium Citri tangerinae extract is put into and the deionized water of 2/3 mass is warming up to 60-80 DEG C of constant temperature stirring 20-30 minute, add Enter phytic acid, γ-mercaptopropyl trimethoxysilane ultrasonic disperse 15-20 minute, stand to obtain modified phytic acid；

(3) poly-aspartate, nano silicon, sodium alginate and balance deionized water are mixed, use high pressure homogenizer Process 2-3 hour, be spray-dried to obtain nano silicon graft modification poly-aspartate；

(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 Form one layer of fine and close thin film as macromolecule film former in metal surface, add modified waste polystyrene foam plastic and make For waterproof agent, add other auxiliary agents, the antirust agent favorable rust preventing effect that preferably prepared by formula, and persistent simultaneously；With existing Have technology compare the present invention phytic acid is carried out silane coupler modified after, generate after-the P-OH-of phytate molecule and silane hydrolyzate -Si-OH-reaction generate-P-O-Si-key, the chelate of the stable hydrogenation of six carbocyclic with chair conformation can be generated with metal, attached In metal surface, corrosion resistance strengthens, and the product stability of chelating is splendid, even if the most also can stably deposit ?；Poly-aspartate nano silicon also carrying out parcel modification, improves the compounding effect with phytic acid, weather resistance increases By force；Raw material sources of the present invention are extensive, and preparation method is simple, low production cost, can effectively prevent metal raw in wet environment Becoming rusty and cause performance to reduce, the present invention also has the antibacterial, worm-expelling of excellence in addition, while antirust, gives metallic article excellent Different anti-microbial property.
