For the present invention using organic fluorinated silicone modified acrylic acid ester emulsion as film forming matter, it has the excellent transparency, film forming, good
Oil resistivity and weatherability well, mechanical stability and good adhesiveness, simultaneously as organic fluorine monomer has higher heat steady
Qualitative, chemical inertness, corrosion resistance and anti-ultraviolet ageing performance, it is modified acrylic emulsion water resistance, oil resistivity, weather-proof
Property, the performance such as chemical resistance is obtained for very big raising, and because the introducing of organic silicon monomer, makes modified propylene yogurt
Stain resistance, resistant of high or low temperature and the water resistance of liquid are improved；In order to further lift the performance of coating, add again
Modified phosphate calcium component, in the preparation process of modified phosphate calcium, first synthesizes to obtain calcium hydroxy phosphate with phosphoric acid and calcium oxide,
It has good surface characteristic, then carries out cladding processing, wherein nanometer titanium dioxide to it with modified nano-titanium dioxide again
Titanium first carries out coupling modifier with silane coupler, improves its scattered, chelating ability, and has carried out modification with modification liquid,
The compatibilities such as nano titanium oxide and organic fluorinated silicone modified acrylic acid ester emulsion after being grafted by methacrylic acid are high, final modified
Nano titanium oxide afterwards wraps that performance is good to the bonding of calcium hydroxy phosphate, improves dispersiveness, the corrosion resistant of modified phosphate calcium again
Property, intensity etc., improve its performance.
The present invention has advantages below compared with prior art：
Addition of the invention rational has been arranged in pairs or groups each material composition, and mutual amalgamation is high, final obtained coating have it is water-fast,
The characteristics of anti-corrosion, rust-preventing characteristic are good, and processing uses technique simple, has good promotional value.
