Description
Technical field
The present invention relates to a kind of protective system, particularly a kind of Scour-resistant anticorrosive paint.
Background technology
In the fields such as ore dressing, chemical industry, oil production, environment-protective water process, ubiquity contains a slurry transferring difficult problem for solid particulate matter at present.Slurry in above-mentioned field is made up of the solid of size particles inequality and liquid mixing, and solid-to-liquid ratio concentration is not from 10% to 70% etc.
Common conveying slurry mode adopts mostly: by stirrer by slurry agitation, make it mix, then by pump, slurry is transferred to the external world by pipeline.In course of conveying, the flow-passing surface of aforesaid device, namely fluid in equipment flow through position not only can and liquid comes into contact; also solid particulate matter can be contacted simultaneously; because solid particulate matter volume size, shape are all irregular, often can be drawn by corner angle, hit flow-passing surface, bring heavy wear to equipment.
In addition, slurry itself often has corrodibility, such as ore pulp material, and because the attribute of mineral own has corrodibility, its slurry also has corrodibility.Thus also abnormal serious to the corrosion of device interior flow-passing surface.
In order to the work-ing life of extension device, reduce equipment use maintenance cost, domestic market has occurred all kinds of coating for flow-passing surface special protection.
Solution common on existing market has, such as:
1, a modified epoxy complex repairation coating, it is single layer structure, mainly using aluminum oxide or silicon oxide as aggregate, is then equipped with the modified epoxy of suitable proportion, solidifying agent, thickening material etc.Described aggregate refers to is repairing the granular loose material playing skeleton or filling effect in coating.This coating has good antiseptic property and wear resisting property, but but fails to properly settle with the associativity problem of substrate surface, this creates the terminal the problem of coating shedding.
2, an epoxy resin composite coating, it is single layer structure, mainly with silicon carbide and aluminum oxide for aggregate, form using epoxy resin, solidifying agent, setting accelerator as binder configuration.This coating has certain effect for common wearing surface reparation, but at bad environments, slurry temperature is higher, flow velocity is fast, particle diameter is large, when corrodibility is stronger, because this coating is in order to resistance to wear, employing be all the silicon carbide and alumina particle that granularity is larger, undesirable to the wetting property of substrate surface, bonding force reduces, in the middle of coating and flow-passing surface, there is Minute pores, cause the tap density of coatingsurface to reduce, between abrasion resistant particles, have gap, wear-resisting and antiseptic property reduces, and even comes off from surface.
So the practicality of above-mentioned two schemes in slurry hauling operation is poor.
Summary of the invention
Based on the defect of prior art, the object of the invention is to propose one and wear-resistant paint is subdivided into according to function: precoated layer, protective layer and upper layer three layers, and the Scour-resistant anticorrosive paint be combined.Find that this coating effectively can avoid coating shedding after tested, in slurry, solids is drawn, is hit, and effectively reduces the resistance in slurry transportation, improves conveying efficiency.Its principle be by improve coating tap density with strengthens resistance to abrasion and improve bonding force, enhancing tear strength.Adopt the scientific matching of differing materials, the coating of difference in functionality combines the treatment effect of solidification its performance rear far above existing single abrasion resistant anticorrosive paint.

Precoated layer for main component, coordinates epoxy resin with titanium dioxide, talcum powder.Epoxy resin can with polytype solidifying agent generation crosslinking reaction and formed and insoluble, molten not there is the cancellated superpolymer of three-dimensional.Titanium dioxide, talcum powder, the Wuli-Shili-Renli system approach that such that precoated layer has reinforcement, fusing point is high, opacifying power good, soft, adsorptive power is strong etc. excellent.This characteristic can guarantee the bonding force of precoated layer and substrate surface.
Protective layer is main component with aluminium sesquioxide, has the characteristics such as high temperature resistant, resistance to grinding, silicon carbide, such that coatings chemistry performance is more stable, thermal expansivity reduces, wear resisting property improves.Protective layer as the main stor(e)y of Scour-resistant anticorrosive paint, thickness general control at 3 ~ 8cm, with aluminium sesquioxide, silicon carbide, wolfram varbide for aggregate is equipped with epoxy resin can this thickness of heap smoothly, and very firm.
Extexine and precoated layer similar, but special emphasis various frictional force in minimizing slurry transportation.
In described A group, aluminium sesquioxide particle diameter is 1 ~ 5um;
In described C group, aluminium sesquioxide is 8 ~ 24 orders, and silicon carbide is 80 ~ 120 orders, and wolfram varbide is 200 ~ 240 orders;
In described D group, wolfram varbide is 200 ~ 240 orders, and aluminium sesquioxide is 80 ~ 130 orders;
In described E group, aluminium sesquioxide particle diameter is 1um.
In precoated layer A group, aluminium sesquioxide particle diameter is that the particle diameter of 1 ~ 5um, 1 ~ 5um is very little, effectively can improve the tap density of precoated layer, strengthens the bonding force on precoated layer and base material top layer.
Employing particle diameter in protective layer C group, D group is comparatively large, but different aluminium sesquioxide, silicon carbide, wolfram varbide are aggregate, guarantees there are enough denseness on the one hand, be convenient to generate thicker protective layer, simultaneously by the combination between different-grain diameter, reduce space, strengthen bonding force.High temperature resistant, the resistance to abrasive characteristic of effective raising protective layer.
In extexine E group, aluminium sesquioxide particle diameter is 1um, adopt the aggregate of aluminium sesquioxide as upper layer of minimum grain size, what can make extexine reaches minimal level in conjunction with gap, brushing is on protective layer, effectively can must fill up space that protective layer particle diameter causes more greatly, depression, form the most smooth surface.
8 ~ 24 order aluminium sesquioxides in described C group, through pre-treatment, put into ball mill shaping 1 ~ 2 hour after it being mixed with 33:2 mass ratio with the zirconium oxide bead of particle diameter 6mm, and shaping uses 10% chlorohydric acid pickling, organics removal and impurity after taking out;
80 ~ 120 order silicon carbide in described C group, through pre-treatment, put into ball mill shaping 1 ~ 2 hour after it being mixed with 1:4 mass ratio with the zirconium oxide bead of particle diameter 4mm, and shaping uses 10% chlorohydric acid pickling, organics removal and impurity after taking out;
200 ~ 240 order wolfram varbides in described C, D group, through pre-treatment, put into ball mill shaping 1 ~ 2 hour after it being mixed with 1:6 mass ratio with the zirconium oxide bead of particle diameter 0.2mm, and shaping uses 10% chlorohydric acid pickling, organics removal and impurity after taking out;

Because aluminium sesquioxide, silicon carbide, wolfram varbide belong to together, quality is hard, the solid particulate of stable performance, although particle diameter is less, out-of-shape, in order to its corner angle of polishing, realizes better bonding properties, therefore carry out pre-treatment in the manner described above.Our experiments show that, pretreated aluminium sesquioxide, silicon carbide, tungsten carbide particle, more close to spherical, are conducive to proportioning and the combination of coating.
Described epoxy resin is epoxy resin E-44 or E-51 or E-54 type.
The invention has the beneficial effects as follows:
Common abrasion resistant anticorrosive paint does not establish precoated layer and extexine, directly by piling on substrate surface, be similar to and directly the protective layer in the present invention be stacked into substrate surface.Owing to needing to guarantee that coating needs certain denseness, hardness; to generate thicker protective layer; so just bring Railway Project: first; if internal particle thing particle diameter is too small; then mixture is similar to liquid; cannot pile up the protective layer to have wear-and corrosion-resistant effect, and the general thickness of slurry transportation equipment protective layer must at more than 3cm at all.Second, internal particle thing is comparatively large, then occur with base material top layer in conjunction with hypodynamic problem, because coating and base material top layer do not belong to allied substances, bonding force one is directly subordinate to an industry difficult problem, when internal particle thing just appears in the problem that in use procedure, big area comes off comparatively greatly.3rd, individual layer cannot solve substrate surface and the excessive problem of slurry contact partial frictional power.The partial frictional power of substrate surface and slurry contact is excessive, and transmission efficiency can be caused low, and machine utilization is large, and easily because aforesaid frictional force and machine utilization problem cause sag of protecting coating further, this point, slurry transport pipeline shows particularly evident.
The present invention, by by traditional abrasion resistant anticorrosive paint, according to the specific requirement in real production work, is broken down into three layers: precoated layer, protective layer, extexine.Wherein precoated layer main purpose is the bonding force strengthening coating and substrate surface, by increasing the composition of epoxy resin, reduces wherein non-solubility solid, and the particle diameter of the aluminium sesquioxide in concrete finger A group reaches the object strengthening bonding force.The combination of the known material of the same type of industry in conjunction with much easier than foreign peoples material, will exceed far away directly on base material top layer, apply protective layer so increase protective layer bonding properties of the same type on precoated layer.Protective layer as main layer of the present invention, its thickness more than precoated layer and extexine thick, effectively realize resistance to erosion rot-resistant object.On protective layer, brushing one deck has very thin, but extremely hard smooth extexine again, and main purpose reduces various frictional force in slurry transportation.
