Aqua region is repaired, and improves waterproof and anti-pollution characteristic.
Technical program of the present invention lies in including following material composition：Water-borne acrylic resin 50-70%, nanometer silane 2-
10%th, strengthen powder 10-30%, defoamer 0.3-1%, antibacterial 0.1-0.3%, thickening agent 0.3-1%, adopt and make with the following method
It is standby,
(1) aqueous synthetic-resin and nanometer silane are put in dispersion cylinder and stir；
(2) enhancing powder and defoamer is added to be mixed and stirred for；
(3) add antibacterial mixing, stir；
(4) add thickening agent mixing, stir；
(5) filter and package.
In above-mentioned (1st) step, mixing time is 20-40min, and in (2nd) step, mixing time is 15-30min.
After above-mentioned (4th) step, viscosity detection need to be carried out to gained coating, k value conformance with standard in 90-100KU,
Otherwise on the basis of (4th) step, continue stirring until viscosity is up to standard.
The beneficial effects of the present invention is：
1st, the resin that above-mentioned coating is selected is water-borne acrylic resin, hence in so that the weatherability of gained coating and resistance to water
Good, aging resistance, uvioresistant, after being applied to metope, tensile strength is moderate, and elongation percentage is more than 200%, and dry film transparency is high, has
Preferably adhesive force, continues 30min waterproof under the pressure of 0.3MP；
2nd, with silane-modified water-repellent paint, in film forming procedure, nanometer silane material part migrates to film coated surface, and one
Partially fill the space between emulsion particle, improve the water resistance of film, some defines in film coated surface
One layer of hydrophobic membrane, produces larger surface tension poor, so rainwater, in the film coated surface formation globule, loses between rainwater and film
Permeability, i.e. so-called lotus leaf effect.Thus reaching waterproof purpose, further, since film coated surface tension force is low, the ash of in the air
