Description
Technical field:
The invention belongs to technical field of paint preparation, more particularly to it is a kind of for steel surface water-base epoxy type anticorrosive paint and
Preparation method.
Background technique:
The resource that the whole world is wasted because of the corrosion of metal material every year accounts for about 1/5th of current year utilization rate, directly
Economic loss is caused to account for 4.2% of gross national product or so, metallic material corrosion not only causes huge economic loss, but also
Potential disaster may be caused to society.Although we are difficult to prevent the generation of corrosion, can by effective aseptic technic
So that the carry out rate of corrosion is effectively inhibited.Currently, mainly using coating for the means of defence of steel surface corrosion
Protection Code is contacted in metal surface one layer of anticorrosive paint of brushing with completely cutting off external corrosion medium with the direct of metallic matrix, from
And play effective corrosion-resisting function.Traditional solvent type coating using organic solvent as decentralized medium, mainly include hydrocarbon, ketone, alcohol,
Ester, ether etc., most of organic solvent are easy to volatilize, so that volatile organic compounds (VOC) is generated, and VOC can cause light
Chemical fumes, this is also one of the main inducing of China's atmospheric haze in recent years.As people are for the attention of environmental protection, no dirt
The principles such as dye, nuisanceless, the saving energy, economical and efficient have become the common recognition of domestic and international coatings enterprises development；And water-repellent preservation
Coating is using water as decentralized medium, so as to greatly reduce the content of VOC, has become the master of the following anticorrosive paint development at present
One of artificial delivery product, however the comprehensive performance of water-based anticorrosive paint still lags behind solvent type anticorrosive paint instantly, for this purpose, accelerating aqueous
The research and development of epoxy type coating are important one of the developing direction in the field.
Due to the property of nano material itself, adding nano material in anticorrosive paint can effectively improve coating
The performances such as mechanical, corrosion-resistant, acid and alkali-resistance.Chinese patent CN104403498A discloses a kind of novel aqueous epoxy anti-rust paint,
It was found that the mechanical performance and corrosion resistance of film can be improved by adding nano zine oxide；Chinese patent CN 104559386A
Disclose a kind of preparation method of nano silicon dioxide modifying water epoxy coating, the coating have extremely low VOC content and
Excellent machinery and corrosion resistance；Chinese patent CN 106893452A discloses the painting of nano rare earth modified epoxy anti-corrosion
Material and preparation method thereof, the coating have good uvioresistant performance and weather resistance.Although nano-material modified for utilizing
The research and development of anticorrosive paint have made some progress, but there are still such or such some problems；Due to nanoparticle
The special nature that son has, specific surface tension and specific surface area are larger, and interaction " attraction " makes nano material between particle
Surface particle is unstable, Yi Jiju, and " reunion " phenomenon occurs, and the poor compatibility with organic media makes answering for nano ZnO
Limitation is used, even if also will appear some agglomerations, in addition, how to enhance nanometer in the grinding of superfast blender, dispersion
The lipophilicity of particle, make nanoparticle preferably with asphalt mixtures modified by epoxy resin lipid phase and hold, be this stage urgent need to resolve critical issue it
One.
Summary of the invention:
It is an object of the invention to overcome the deficiencies of the prior art and provide one kind to apply for steel surface water-base epoxy type anti-corrosion
The preparation method of material.It is provided by the invention a kind of for steel surface water corrosion-resistant epoxy paint, the water-base epoxy type anticorrosive paint
