Abstract
A kind of protective system is used for for a long time under high and low temperature environment and has under the weak acid and weak base atmosphere, often contacts inside and outside equipment anticorrosion and antirust of salt fog and humid atmosphere.Poly phenol oxygen resin, polyamide-imide resin then are made up of antimonous oxide and two alkali or Lead Phosphite, Dibasic (Coated) as binding agent, rust-preventive agent, with plumbous oxide, rare earth fluoride as antioxidant addn, add composition protective systems such as tensio-active agent again, the anti-rotten coating of protection adds in the mixed organic solvents makes spray, be sprayed on the parts surface after normal temperature solidified in 4-6 hours, become the solid film firm, the densification of coating internal structure that bonds, have favorable protection antiseptic property and excellent high-low temperature resistant ability.
Description
The present invention relates to a kind of protective system, it is applicable to anticorrosion and antirust on the equipment such as building, metallurgy, medicine, chemical industry, oil field.
For the corrosion and the corrosion of minimizing equipment and component, people use rust-inhibiting paint usually.Under some special operation condition condition, as high low temperature humid atmosphere, under open-air, the alkaline environment, general protective system is just very short work-ing life, even the occasion that has can not be used at all.At present both at home and abroad manyly solve above problem as the protective system of binding agent with epoxy resin, polyurethane kind and acrylic acid or the like.But weak point coating majority is two components, must field mix during construction.General set time is also longer, and needs heating cure, and this will certainly influence the use range of coating.
The object of the present invention is to provide a kind of single-component, ambient cure protective system, it suits to use in weak-alkaline and weak-acidic condition and wide temperature range.
Another object of the present invention provides the preparation method of protective system.
Purpose of the present invention realizes by following measure:
The present invention is made up of compositions such as binding agent, solid packing, rust-inhibiting additive, antioxidant, tensio-active agents.Binding agent adopts phenoxy resin and polyamide-imide resin, and solid packing is talcum powder and silicon carbide, and rust-inhibiting additive is selected antimonous oxide and dibasic lead phosphite for use, and antioxidant is by rare earth fluoride and Pb
3O
4And/or PbO forms.The concrete prescription of protective system is (weight); Phenoxy resin 3-13%, polyamide-imide resin 20-48%, talcum powder 19-33%, silicon carbide 0-10%, antimonous oxide 1-6%, dibasic lead phosphite 1-7%, cerium fluoride 2-9%, Pb
3O
4And/or PbO 9-25%, tensio-active agent 1-5%.
Select for use phenoxy resin, polyamide-imide resin as binding agent, can make coating fast setting at normal temperatures, and cohesive strength is preferably arranged, temperature tolerance, preservative property, resistance to weathering can be guaranteed.
The tensio-active agent that the present invention selects for use is one of important factor of ambient cure coating, can be Si Ben-20, tween-80, and cetyl trimethylammonium bromide, amination wilkinite, but preferably select hexadecyl trimethyl ammonium bromide for use.
The phenoxy resin molecular weight that the present invention selects for use for the 25000-35000 structural formula is:
The polyamide-imide resin absolute viscosity that the present invention selects for use is the 2500-6000 centipoise, and structural formula is:
Binding agent in the present invention's prescription, properties-correcting agent, solid packing, rust-preventive agent, antioxidant etc. all are powder solid or thick liquid before not making coating, therefore, when the preparation protective system, need be made into the coating spray sprays, concrete preparation method is scattered in the solid particulate in the prescription by in the blend medium of dispersion medium dissolved binding agent, properties-correcting agent, by prescription of the present invention, powder material is added in the blend dispersion medium, after abundant grinding, make the soup compound spray.It is the mixed solution of dimethylbenzene (toluene), butanone, dimethyl formamide, dioxane that dispersion medium is selected organic solvent for use, and add-on is the 2-3 of prescription material doubly (weight), the consisting of of dispersion medium: dimethylbenzene (toluene) 4-23%.Butanone 8-36%, dimethyl formamide 50-80%, dioxane 2-14%(volumn concentration), why select this four kinds of solvents for use, be to fully take into account set time, factors such as cohesive strength.
Solid material purity requirements such as the solid packing that the present invention selects for use, rust-preventive agent, antioxidant are greater than 90%, and granularity is below 10 microns.
The present invention is applicable to the anticorrosion, antirust of various metallic surfaces, as pipe-line equipments such as metallurgy, medicine, chemical industry, power plant, oil fields, be particularly useful for shelving in the open, the mechanical means that a large amount of wet environments use often contacts the drilling unit etc. of seawater salt fog and is in corrosive gases such as soda acid for a long time and object antiseptic and rustproof at the chemical industry equipment of high-temperature vapour environment.
Protective system of the present invention, be fit to be sprayed on the machining surface and the lapped face of various carbon steels, stainless steel, steel alloy, copper, aluminium, magnesium and materials such as alloy, cast iron thereof, also can be sprayed on the metallic substance workpiece surface of sandblast, phosphatization, sulphonitrocarburizing, anodic oxidation, passivation.
The present invention has following advantage:
1, single-component
2, ambient cure
3, lack set time, only need 4-6 hour.
4, use temperature wide ranges can be used down at-60 ℃-220 ℃
5, the key technical indexes is listed in table 1 and table 2.
Table 1:
* the ammoniacal liquor of boiling water adding pH11-12 is 200 hours.
Embodiment:
Take by weighing solid packing by table 3 prescription, be ground to required granularity, add in 1/3rd dispersion medium, take by weighing poly phenol oxygen resin, polyamide-imide resin, tensio-active agent, add its dissolving and front batching are mixed mutually, grind back last 1/3rd dispersion medium of adding and carry out blending and stirring and evenly be the protective system spray.The spray for preparing is sprayed on it on workpiece according to a conventional method, and the specific performance index saw Table 1 and table 2 with regard to curable one-tenth coating in 4-6 hour under the normal temperature situation.
* weight percentage.
