Description
Technical field
The present invention relates to field of material technology, more particularly to a kind of erosion of turbine blade modified epoxy coating antiseptic is anti-
Abrasion method.
Background technology
Abrasion wear phenomena all generally existing in many industries such as water conservancy, water power, machinery, weaving and metallurgy, and non-
Chang Yanchong, the economic loss for thereby resulting in can quite show.China is very huge in the spending of this aspect, especially water conservancy, water power
Department more projects.This is because China's silt content of river is big, complete excessively annual river of the sedimentary loading more than 10,000,000 tons of transporting is up to 115
Bar, according to first place in the world.Calendar year 2001, relevant statistics showed Ml, national power station total installation of generating capacity be 80.05GW, gross generation
For 2184.5 hundred million kW/h, positioned at big areas of silt content of river such as northwest, southwest and North China, these are regional for wherein 105,600,000,000 kW h
Component of Hydraulic Turbines not only washed away by high-velocity flow, denuded and mechanical force is acted on, but also by being mingled with current
The abrasion of the media such as silt, ablation destruction, therefore the consume of material is very serious.In addition, in the power station of Central-South, East China,
Although Component of Hydraulic Turbines is received because silt content of river is few, and sand erosion loss is little, the cavitation of current is at deep water to water
The destruction of engine blade wheel material is then quite serious.Data shows according to the relevent statistics, and a large-scale power station is used for changing, repairing every year
Therefore the expense of water conservancy machinery, solves hydraulic abrasion, erosion problem up to more than million yuan, very necessary.
A kind of most economical, most efficient method is exactly the high anti-corrosion painting of coating high abrasion on the blade and arbor of the hydraulic turbine
Layer, and wear resistant corrosion resistant metal coating is favored by people deeply as its coating processes is simple, economic and effect is obvious.
Content of the invention
It is an object of the invention to proposing a kind of turbine blade modified epoxy coating antiseptic loses abrasionproof etching method, energy
Turbine blade anti scuffing anticorrosive is enough made.
, including metal coating layer material, there is coating hardness and toughness be difficult to the contradiction taken into account, improve in traditional coating material
The hardness of coating often to sacrifice its toughness as cost, causes coating to decline with skin and associativity with matrix.Big when being subject to
When particle impacting, abrasion, coating is easy to crack, hard phase is easy to fall off.
It is that the present invention is employed the following technical solutions up to this purpose：
A kind of turbine blade anticorrosion abrasionproof etching method, which includes：
(1) sandblasting roughening is carried out in blade surface；
(2) with acetone and ethanol purge roughening blade surface and dry；
(3) account for 20-45wt%, terminal hydroxy liquid rubber modified epoxy resin surplus according to hard TiN ceramic particles to match somebody with somebody
Than making slurry mix homogeneously；
(4) by the slurry uniform application in blade surface, dry at 90-130 DEG C, cladding is obtained in blade surface
The terminal hydroxy liquid rubber modified epoxy resin abrasion-proof corrosion-proof erosion resisting coating of TiN doping.
The present invention improves both compatibilitys, and shape using the liquid rubber modified epoxy resin containing terminal functionality
Into inierpeneirating network structure or half interpenetrating network structure, as terminal functionality liquid rubber contains butadiene long-chain, itself tool
There is preferable pliability, the modified epoxy that therefore present invention is adopted has toughness, the nonmetallic painting that therefore which prepares
Layer good toughness, hardness are high, overcome the defect that conventional coatings hardness can not be taken into account with toughness.
The preparation method of terminal hydroxy liquid rubber modified epoxy resin of the present invention is the state of the art, this
Art personnel can be selected in the range of prior art.Typical but non-limiting example is as follows：
First by terminal hydroxyl polybutadiene liquid rubber or end hydroxy butadiene/acrylonitrile liquid rubber and polyisocyanates
Polyisocyanates terminated polybutadiene liquid rubber prepolymer is produced in reaction or polyisocyanates polybutadiene/acrylonitrile liquid rubber is pre-
Then the prepolymer is reacted with epoxy resin, prepares terminal hydroxy liquid rubber modified epoxy resin by polymers.
The terminal hydroxy liquid rubber modified epoxy resin that the present invention is adopted, terminal hydroxyl polybutadiene liquid rubber is introduced by which
In the cross-linked network of epoxy resin, play toughening effect, due between terminal hydroxy liquid rubber and various modified components with chemistry
Bond is closed, and not only can retain the high-adhesion energy between epoxy resin and metal, and there is liquid rubber high flexible again
Property, thus obtained terminal hydroxy liquid rubber modified epoxy resin possesses the unification of pliability and hardness.
Preferably, epoxy resin of the present invention, its structural formula is：
In formula, G is epoxide group, and R is H or alkyl, and n is the integer of 2-4.
Preferably, in modified epoxy of the present invention, doped with additives such as firming agent.
The present invention is blended in the modified epoxy as wear-resistant noncorroding metal ion using TiN.Titanium nitride
(TiN) there is typical NaCl types structure, belongs to face-centered cubic lattice, lattice paprmeter a=0.4241nm, wherein titanium atom are located at face
The angle top of the heart cube.TiN is non-stoichiometric compound, its stable compositing range be TiN0.37-TiN1.16, the content of nitrogen
The change of TiN structures can not caused in change in certain scope.Typically in yellowish-brown, ultra-fine TiN powder is in TiN powder
Black, and TiN crystal is in golden yellow.TiN fusing points are 2950 DEG C, and density is 5.43-5.44g/cm3, Mohs' hardness 8-9, heat resistanceheat resistant
Impact is good.TiN fusing points are higher than the fusing point of most of transition metal nitrides, and density is lower than most metals nitride,
Therefore which is the inorganic particulate of reasonable wear resistant corrosion resistant and high temperature resistance.
Preferably, TiN ceramic particles account for 30-40wt%, further preferred 35wt%.
The wear-resistant coating that the present invention is prepared, which is tightly combined with matrix, and bond strength is more than 800MPa, service life
Extend more than 6-7 times compared to the blade without coating, anti-cavitation ability improves more than 10 times.
The terminal hydroxy liquid rubber modified epoxy resin abrasion-proof corrosion-proof erosion resisting coating of the TiN doping that the present invention is prepared, its
Possesses the advantage of ceramic coating, the characteristics of but also with Organic substance good film flexibility, not only anti scuffing, anticorrosive, and pliability is also
Good.Through trying out 1 month in waste stream, significantly abrasion and evidence of corrosion is not found.
