Description
Technical field
The present invention relates to paint field, anticorrosion, fireproof steel structure special coating and its preparation side are further related to
Method.
Background technology
In recent years, the increasingly popularization with the country to assembled architecture, more and more using steel construction as main load-bearing material
The building of material occurs in life.Steel intensity is high, performance is stable, good toughness, and is suitable for batch production so that steel into
For Optimum Building structural material.But steel construction has two big invisible hidden danger in application process：Fire and corruption
Erosion.When environment temperature is higher than 500 DEG C, the weight capacity of steel construction can drastically decline, and cause collapsing for building, cause personnel to hinder
Die.Meanwhile, steel are easily corroded, and the steel loss caused by corrosion every year reaches the 10%~20% of steel production.
It not only causes damage to economy, while causing corresponding pollution to environment.Therefore, anti-corrosion is 2 weights of steel construction with preventing fires
Want engineering.It is 2 kinds of relatively conventional means that anti-corrosion, which is coated, with fireproof coating.
General way is at present：One layer of rust resistance and corrosion resistance priming paint is coated on steel structure surface, then above again
Brush one layer of fireproof coating.There are two big defects in this way：1) antirust, anti-corrosive erosion resisting coating is typically lead red alcohol acid resin or richness
Zinc epoxy resin, severe contamination is caused to environment；2) cohesive force has different between antirust, anti-corrosive erosion resisting coating and fire resistant coating,
Compatibility is bad, and two coatings of material can be peeled off, come off after long-term use, and then loses the protection to bottom material, thus
Reduce the service life of material.Up to the present, there is not yet related with the coating of steel structure fireproofing, corrosion proof function
Patent and document report.
The content of the invention
The first aspect of the present invention provides a kind of anticorrosion, fireproof steel structure special coating, in parts by weight, at least
Including following components：
50-75 parts of polyurethane resin, 15-33 parts of super branched polyacrylate, 40-50 parts of amino resins, epoxy emulsion 15-
24 parts, 15-28 parts of hydroxyethyl cellulose, 20-33 parts of chitosan microcapsules, 18-30 parts of nanometer hydroxyapatite, nanometer titanium dioxide

100-200 parts of ionized water；
The preparation method of the chitosan microcapsules is as follows：
(1) hyper branched polyphosphate ester, cetyl trimethylammonium bromide are dissolved in ethanol solution, surpassed at 50 DEG C
Sound disperses 30min, obtains hyper branched polyphosphate ester solution；
(2) chitosan is dissolved in pH value in 3.5 acetums, and is 7 with sodium hydroxide regulation pH value, obtain chitosan
Solution；
(3) hyper branched polyphosphate ester solution average rate is instilled in chitosan solution with syringe, stands 12h and solidified,
Washed again with ethanol, 40 DEG C of vacuum drying obtain chitosan microcapsules；
The preparation method of the modified magnalium hydrotalcite is as follows：
Magnalium hydrotalcite is added in ethanol, ultrasonic disperse 60min is carried out at 80 DEG C, magnalium hydrotalcite solution is obtained；
Amination graphene is added in ethanol, ultrasonic disperse 20min is carried out at 30 DEG C, amination graphene is obtained molten
Liquid；
Amination graphene solution is added dropwise in magnalium hydrotalcite solution, control pH be 4-5, rotating speed be 50 turns/
Point, after reaction 5h, filter and dry 8h with vacuum drying oven at 40 DEG C, obtain being modified magnalium hydrotalcite.
It is used as a kind of preferred scheme of the present invention, the anticorrosion, fireproof steel structure special coating, with parts by weight
Meter, at least including following components：
