Description
Technical field
The invention belongs to coating preparation technology neck is and in particular to a kind of novel environment friendly solar energy water storage tank anticorrosive paint.
Background technology
The utilization technical field of solar energy, is broadly divided into Photo-thermal technology application and photovoltaic application.Photo-thermal technology application technology mainly has too
Sun can hot-water heating system, heating refrigeration system, heat generating system etc.；Photovoltaic application technology includes solar power system.China has
Abundant solar energy resources, therefore Solar use association area obtain the support energetically of country, and solar water heater is as too
A kind of industry that sun can utilize, becomes most widely used in solar energy heat utilization, the most rapid field of industrialized development.China
70% that total amount promoted by Liang Zhan world solar water heater promoted by solar water heater, exceedes the summation that American-European countries promotes for 10 years,
It is " world's solar energy production and application total amount first big country ".
Thermal storage water tank is main devices using solar energy, and the development that its development represents whole water heater is gone through
Journey, but its using process in the middle of exposed day by day go out its drawback；Lead to the generation of electrochemical corrosion.Ordinary carbon steel storage heat
Water tank can form flakey oxide skin in the operations such as high temperature hot rolling, but the coefficient of expansion of this oxide skin is less than steel；In addition water
Case is chronically in the hot water environment that 30-80 DEG C of temperature becomes, and is vulnerable to the corrosive environment such as water and oxygen in water, chlorine molecule or ion
The erosion of medium and produce micro-crack, the consequence such as lead to steel plate local perforations leak, water tank to be scrapped, the immediate cause of its problem is just
It is the corrosive environment directly contact such as steel plate and hot water.
Method using anticorrosive coating can not only be separated above-mentioned corrosive medium and plain steel effectively, and coating
Can act on stoping or to delay the corrosion of water tank by shielding, inhibition and passivation, electrochemical protection etc..This method economically than
Adopt merely stainless steel water tank economy, the weld defect of stainless steel water tank stack shell longitudinal seam presence, magnesium rod can be overcome simultaneously again to disappear
The shortcomings of consumption is too fast, replacing is frequent.Facts have proved: in numerous anticorrosion techniques, high using external coating antiseptical ratio
Reach 65%, be to be acknowledged as most economical, effective, universal anti-corrosion method at present.If but imperfection, painting design are processed to matrix
It is improper to select, coating meeting premature failure, does not reach preferable protection effect and causes certain economic loss and cannot make up.Mesh
Before, existing document report adopts organic titanium, polyurethane rock crystal paint, lkf-1 glass-flake coating, laccol aluminium powder Berlin black, rubber and plastic
The anti-corrosive organic coatings such as composite coating, but underfilm corrosion can be caused after water tank comes into operation earlier (bubbling, stripping, wet
Adhesive force is lost) and make water tank retired in advance, its protection effect is not good.For this reason, research is applied to carbon steel in hot water environment
The anticorrosive paint of water tank is particularly important, and has realistic meaning.
Content of the invention
The present invention provides a kind of novel environment friendly solar energy water storage tank anticorrosive paint, to solve traditional coating for carbon steel water
Case is anti-corrosion, easily causes bubbling, and the problems such as resistance to water, resistance to ag(e)ing, pliability, poor impact resistance.The coating of the present invention
Both there is excellent adhesive force and mechanical property, there is excellent resistance to water, resistance to ag(e)ing, pliability and resistance to impact again,
And asepsis environment-protecting, can effectively delay the service life of carbon steel water tank, be more beneficial for the popularization of solar water heater.
