Description
Technical field
The present invention relates to protective system field, being specifically related to a kind of super-fine zinc dust, nano concave earth, inorganic adhesive of adopting is nano concave earth inorganic zinc-rich protective system of making of main raw material and preparation method thereof.
Background technology
Corrosion of metal, refers to that metal is subject to the chemistry of surrounding medium or electrochemical action and destroyed phenomenon.Corrosion of metal, throughout national economy every field, brings huge loss to national economy.About 100,000,000 tons, the metal scrapped is corroded in the annual whole world according to statistics, accounts for 20% ~ 40% of annual production.At present, the financial loss that causes because of corrosion of metal structure every year of the whole world is up to more than hundreds billion of dollar.For a long time, people adopt multiple technologies to be protected metal always, prevent the generation of corroding.Wherein, one of method that hardware protection against corrosion is effective, the most the most frequently used is at metallic surface coating protective system.
Zinc-rich paint is owing to both having the shielding effect of physical property, and have again electrochemical galvanic protection effect, being thus widely used in the protection against corrosion of pipeline, bridge, vehicle, chemical industry equipment, boats and ships etc., is one of current the most widely used heavy-duty coating.According to the difference of filmogen, zinc-rich paint can be divided into organic zinc-rich paint and the large class of inorganic zinc coating two.Organic zinc-rich paint is for filmogen with synthetic resins (as epoxy resin, poly-vinegar resin etc.), with the rust proof paint that high-content zinc powder is color stuffing, owing to there is volatile organic matter (VOC) in organic zinc-rich paint, thus it has larger negative impact to environment.Inorganic zinc coating is with the aqueous solution of alkalimetal silicate for film forming base fluid, and the high-performance inorganic coating composite with zinc powder.Compare organic zinc-rich paint, inorganic zinc coating environmental protection (VOC free), temperature tolerance are high, are one of environment-friendly type coatings of most development prospect in the world at present.
Inorganic zinc coating has above-mentioned advantage, but also comes with some shortcomings simultaneously: in the coating of inorganic zinc coating, Zn content is more than more than 70%, and comparatively " crisp " impact resistance is not good for coating; Coating and basal body binding force are not high easy to crack, can produce the holiday etc. of be full of cracks.These factors have impact on Corrosion Protection and the comprehensive mechanical property of inorganic zinc coating, limit the widespread use of this coating.
Publication number is that the Chinese invention patent application of CN101418150A discloses a kind of novel waterborne zinc-rich anti-corrosive paint, is made up of first, second component, in this coating total weight percent, comprises: first component, zinc powder 50% ~ 56%, thixotropic agent 10% ~ 15%; Second component, potassium silicate 8% ~ 10%, water 17% ~ 20%, thickening material 1% ~ 2% and auxiliary agent 4% ~ 7%, during use, first, second component mixes and obtains waterborne zinc-rich anti-corrosive paint.Composite by said components, improves the antiseptic property of coating, meanwhile, has good sticking power, high thermal resistance and ageing resistance, make it have long-effective corrosion effect.But the mechanical property of this waterborne zinc-rich anti-corrosive paint is not good, as resistance to impact shock and snappiness are all poor, its mechanical property needs to be improved further.
