Description
Technical field
The present invention relates to painting technical field, particularly a kind of fan blade freezing coating and preparation method thereof.
Background technology
Wind energy as a kind of renewable, pollution-free and green energy resource of Sustainable development, rich reserves, inexhaustible, nexhaustible.Large-scale developing and utilizing of wind energy, effectively will reduce the use of fossil energy, reduce greenhouse gas emission, protection of the environment, greatly develop the important selection that wind energy has become countries in the world government.
THE WIND ENERGY RESOURCES IN CHINA is enriched, flourish along with China's Wind Power Generation Industry, the constantly progress of fan blade coating and technology thereof.Because China's wind technology starting is more late, fan blade coating technology is complete in abroad introducing at first, tempo is more slow, but China's coating industry development and China special geographical environment impact under, in recent years, fan blade coating is rapidly developed, and meet or exceed import brand by the fan blade coating products performance of China's independent development, the production domesticization of fan blade coating is further developed.But because fan blade is very easily icing in the winter time, affect dynamic equilibrium, and fan blade rotating speed is higher, centrifugal force is comparatively large, and in serious unbalance situation, blade will rupture, suffer heavy losses, and even jeopardizes personnel safety, and consequence is hardly imaginable! All the time, fan blade freezing problem annoyings fan blade producer of China, the development of serious obstruction China wind energy and the advance of technology.
And the problem how solving fan blade icing is study hotspot both domestic and external always, in recent years, there is following several solution: a kind of method is that ice gets rid of by the centrifugal force produced when utilizing vane rotary, but can increase the weight of rack load, causes acceleration components aging; Two is on blade, install heater strip additional exactly to blade heating, and this will consider the problem of lightning protection and Heating temperature, moreover but because underheating causes local or fringe region to freeze seriously in reality is implemented; Three is exactly blade painted black, but summer, blade high temperature may make deformable blade, affected generating efficiency.
Summary of the invention
For the deficiencies in the prior art, the object of the present invention is to provide the coating that can reduce fan blade and freeze, and the preparation method of fan blade freezing coating is provided.
Technical scheme of the present invention realizes (the present invention is raw materials used is commercially available prod of the prior art) like this: fan blade freezing coating, is made up of component A and B component, and the quality proportioning of component A and B component is 1.5:1; Composition and the massfraction of each material in component A of component A are as follows: tetrafluoro resin: 43.0 ~ 48.0%, dispersion agent: 1.4 ~ 2.0%, Rutile type Titanium Dioxide: 20.0 ~ 24.0%, carbon black: 0.2 ~ 0.4%, nano aluminium oxide: 5.0 ~ 8.0%, defoamer: 0.2 ~ 0.3%, flow agent: 0.2 ~ 0.3%, matting agent: 4.0 ~ 6.0%, surface-modifying agent: 2.0 ~ 3.0%, N-BUTYL ACETATE: 4.0 ~ 12.0%, 1-Methoxy-2-propyl acetate: 4.0 ~ 12.0%; B component is HDI tripolymer.Filler selects stable performance, high, the anti abrasive nano aluminium oxide of hardness, as the CH4N-21 of addition chemical industry, improves the abrasion resistance properties of fluorine carbon film, to meet the wear-resisting requirement of fan blade coating.
Above-mentioned fan blade freezing coating, described tetrafluoro resin is the fluorocarbon resin GK570 of Daikin (DAIKIN) company.Because fan blade needs longer work-ing life (at least 20 years), therefore fan blade film performance requires corresponding higher, fluorocarbon resin coating has excellent guarantor's light unfading, weather resistance will far away higher than other type coatings, so have the title of " coating king ", film-forming resin of the present invention uses tetrafluoro resin, as the GK570 of Daikin (DAIKIN) company, can provide good weathering resistance and water resistance, the weathering resistance of its excellence take urethane as the fan blade coating of film-forming resin higher than what generally apply in the market far away.
Above-mentioned fan blade freezing coating, described HDI tripolymer is the N3390 of German Baeyer (bayer) company.HDI tripolymer selected by solidifying agent, can provide comparatively high-weatherability, wear resistance and chemical stability.

Above-mentioned fan blade freezing coating, described defoamer is the BYK-051 of German BYK company.Defoamer is selected and is not broken alveolitoid defoamer containing organosilicon, and it has best defoaming effectiveness in polar system, is suitable for fan blade spraying and roll coating process.
Above-mentioned fan blade freezing coating, described flow agent is the BYK-354 of German BYK company.Flow agent selects the BYK-354 of BYK company, can improve levelling property and the gloss of film, and it produces long wave effect, and prevents shrinkage cavity, and does not affect ply adhesion and recoat performance, does not affect the repairing of fan blade coating and is coated with.
Above-mentioned fan blade freezing coating, described matting agent is the OK412 of German Degussa (Degussa) company.Matting agent, for adjusting the gloss of film, because fan blade film requires to design lower gloss, therefore adds the good flatting silica of stability, as DegussaOK412, has higher flatting efficiency and stability in storage.
Above-mentioned fan blade freezing coating, described surface-modifying agent is the BYK-3700 of German BYK company.Surface-modifying agent selects the BYK-3700 of BYK company, it is a kind of organic-silicon-modified acrylate, blade fluorine carbon film hydrophobic and oil repellency can be increased, therefore scolding water and scolding oiliness of film can be significantly improved, in addition, can also being covered with dust property be reduced, and improve the easy cleaning of film coated surface, substantially increase the water resisting property of fan blade coating, freezing performance.
The preparation method of above-mentioned fan blade freezing coating, comprises the steps:
(1) preparation of component A: N-BUTYL ACETATE and 1-Methoxy-2-propyl acetate are mixed and made into solvent, first in solvent, tetrafluoro resin and dispersion agent is added by formula ratio, after stirring, add Rutile type Titanium Dioxide successively, carbon black and nano aluminium oxide, after being uniformly dispersed, be placed in grinding machine for grinding, mesh-of-grind is less than or equal to 20 microns, ground mill base is placed in clean stirring tank, add defoamer successively under agitation, flow agent, matting agent and surface-modifying agent, fineness less than 30 microns is stirred to after mixing, then filter and package and be component A,
(2) preparation of B component: take HDI tripolymer by formula ratio, filter and package and be B component;
(3) component A and B component carry out joining paint according to the ratio that quality proportioning is 1.5:1, then stir evenly and obtain fan blade freezing coating.
Fan blade freezing coating of the present invention adopts component A and B component to form, wherein, component A is using tetrafluoro resin as hydroxy component, add dispersion agent, flow agent, defoamer, matting agent, surface-modifying agent and various pigment, filler, solvent composition, B component is using HDI tripolymer as curing agent component, and the fan blade freezing coating prepared has snappiness, high-wearing feature and high-weatherability.
The invention has the beneficial effects as follows: fan blade freezing coating of the present invention is applicable to the maintenance of the fan blade under the severe environment such as China land and ocean, there is excellent weathering resistance, protect light and protect the features such as look, wear-resistant, snappiness, lower temperature resistance and outstanding freezing; Make fan blade surface not freeze or reduce to freeze, avoid or effectively reduce the icing phenomenon of fan blade under the weather condition of cold, thus ensure that fan blade normally works, 20 years are reached to the protection life-span of fan blade.
