Abstract
A special apparatus for producing an epoxy zinc-rich primer comprises a grinder, a mixing barrel, a screw propeller and a mixing reaction tank, and the grinder is sequentially connected with the mixing barrel, the screw propeller and the mixing reaction tank. The epoxy zinc-rich primer produced in the invention completely is a solid, has high melting and boiling points, is convenient to transport and store, has no secondary pollution, has high content of solid components, has performances meeting technical matching requirements, saves time and labor, has no humidity or dew point restriction in the construction process, and is especially suitable for being constructed in perennial dark and moist regions; the above product has high melting and boiling points in the drying process, so a vent pipe is avoided, the film storing performance is enhanced, the salt spray resistance reaches 2000h, and the product corrodes corrosion; and the product epoxy zinc-rich primer also has the advantages of simple preparation process, no secondary pollution, cost saving and environmental protection.
Description
Technical field
The present invention relates to chemical industry field of coating, be specially a kind of specific equipment producing epoxy zinc rich primer.
Background technology
Epoxy zinc rich primer is with epoxy resin, zinc powder, for main raw material, the speciality coating product of the composition such as anti-sagging agent, filler, auxiliary agent, reactive thinner, this paint seasoning is fast, and strong adhesion, has stronger anticorrosion effect.Be suitable for the supporting priming paint of anticorrosion coat, for mine, derrick, shipbuilding, port and pier, steel construction, bridge, steel tower, petroleum pipe line, chemical industry, metallurgical steel construction and chemical industry equipment etc.
Conventional epoxy zinc rich primer mostly is solvent based coating, containing a large amount of organic solvent, is harmful to and contaminate environment workmen's health.Along with the development of technology, start the research and development launching water-borne coatings abroad, but the substrate treatment of water-based epoxy zinc-rich primer, construction environment, supporting coating needs are higher.Epoxy zinc-rich requires that zinc content is more than 60%, and zinc powder proportion is larger easily produces hard-caked sediment in coating.Zinc powder is relatively more active, and easy and water reacts releasing hydrogen gas, there is potential safety hazard.
Because solvent-free type epoxy zinc rich primer is type material, present domestic market does not have the equipment of professional production solvent-free type epoxy zinc rich primer, commercially available solvent type epoxy zinc rich primer contains a large amount of solvent, inflammable and explosive, and solvent is larger to operator's injury.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, thus provide a kind of specific equipment producing epoxy zinc rich primer, its solvent-free type epoxy zinc rich primer produced is 100% solid, molten boiling point is high, and flash-point is high, is convenient to transport and stores, environmentally-friendly sanitary simultaneously, non-secondary pollution.
Technical scheme of the present invention is: a kind of specific equipment producing epoxy zinc rich primer, comprises shredder, tempering tank, water screw, hybrid reaction groove, it is characterized in that: described shredder is connected to tempering tank, water screw, hybrid reaction groove successively.
Compared with the prior art the present invention has the following advantages:
1. safety and environmental protection: solvent type epoxy zinc rich primer contains a large amount of solvent, inflammable and explosive, and solvent is larger to operator's injury.And the epoxy zinc rich primer that the present invention produces is 100% solid, molten boiling point is high, and flash-point is high, is convenient to transport and stores, simultaneously environmentally-friendly sanitary, non-secondary pollution.
2. easy construction: high solid, material performance just can reach complete sets of Techniques requirement, time and labour saving.Without humidity, dew point restriction in construction, the long-term dark and damp area construction of particularly suitable.
3. the antiseptic power of excellence: it is high that non-solvent epoxy zinc rich primer drying process melts boiling point, avoids breather line, enhances rete envelope and hides performance, reaches 2000 hours by detecting salt fog resistance.
4. comprehensive cost is low: use non-solvent epoxy zinc rich primer, and surface treatment is simple, and operation is simple, and non-secondary pollution is more durable in use.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described.
Fig. 1 is device structure schematic diagram of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.
A kind of specific equipment producing epoxy zinc rich primer in the present invention, comprises shredder 1, tempering tank 2, water screw 3, hybrid reaction groove 4, it is characterized in that: described shredder 1 is connected to tempering tank 2, water screw 3, hybrid reaction groove 4 successively.
Working process of the present invention is: bisphenol A type epoxy resin 50Kg, glyceryl monostearate 1.5kg, trihydroxymethylpropanyltri diglycidyl ether 20kg, polyamide wax 1.5kg, zinc powder 80kg are put into shredder 1, ball milling 4 hours, being milled to fineness is 50 microns, makes zinc powder mixture.Add glyceryl monostearate, polyamide wax to improve the application performance such as easy solidification, pore-free, no sag of epoxy zinc rich primer, add trihydroxymethylpropanyltri diglycidyl ether, to promote priming paint sprawling in metallic surface, improve the coating homogeneity of priming paint in metallic surface.
In tempering tank 2, add above-mentioned obtained zinc powder mixture 153kg, 2,4,6-tri-(dimethylamino methyl) phenol 10kg, benzoglyoxaline Urethylane 1.5kg, polydimethylsiloxane 0.5kg mix and blend, stirring velocity is 2000 revs/min, stir after 30 minutes, be forced into 3.5MPa, be warmed to 95 DEG C, react 1.5 hours, be cooled to 70 DEG C, be incubated 30 minutes, obtain component A.Add benzoglyoxaline Urethylane, improve resistance to corrosion, add polydimethylsiloxane, eliminate the bubble that may exist in priming paint, prevent from coating procedure, occur uncoated blank spot, add 2,4,6-tri-(dimethylamino methyl) phenol, in order to improve system viscosity, make system keep uniform and stable suspended state or milkiness state, or form gel, there is thickening, suspension, emulsification, the several functions such as stable, improve sticking power.
In water screw 3, add cardanol formal diethylenetriamine 60kg, succimide 60kg, 2 successively, 4,6-tri-(dimethylamino methyl) phenol 1.5kg, toluene glycidyl ether 20kg, fully stir, rotating speed 3000 revs/min, stirred at ambient temperature starts after 30 minutes to heat up, temperature rise to 85 DEG C, react 1 hour, be then cooled to 50 DEG C, be incubated 30 minutes, be uniformly dispersed, obtain B component.Cardanol formal diethylenetriamine; its natural long side substitution phenolic aldehyde amine; there is the feature compared with high hydrophobicity; water sensitivity and other system component of phenolic hydroxyl can be cancelled out each other; thus reduce the probability of resin bond protective layer damage, and increase corrosionproof protection, there is backward reaction after absorbing moisture in succimide; regeneration polyamine, therefore can at moist or underwater curing epoxy resin.
Get component A 11kg and B component 2kg, add in hybrid reaction groove 4 and fully stir, rotating speed 1000 revs/min, stirred at ambient temperature 60 minutes, makes epoxy zinc rich primer.
