Described 40% potassium hydroxide solution can replace with 40% sodium hydroxide solution.
Described acrylic acid series polyocarboxy acid type thickening material is thickening material AT-06.
The fineness of described water-ground limestone and calcined kaolin is 600～800 orders.
It is the water-based oxygen carbon resin of F500 that described water-based fluorocarbon resin is selected trade names for use.
The preparation technology of this highly effective rainproof rainproof paint is characterized in that preparation process is as follows:
In deionized water, drop into polycarboxylate type dispersion agent, defoamer BA-202, frostproofer propylene glycol, sanitas LXE, 40% potassium hydroxide solution and film coalescence aid alcohol ester-12, and to mix under 200～300 rev/mins the stirring velocity; Add nano silicon oxide, nano-titanium oxide, Rutile type Titanium Dioxide, water-ground limestone and calcined kaolin then, under 800～1500 rev/mins high-speed stirring condition, mix; Reduce mixing speed to 300 rev/min, add pure-acrylic emulsion and water-based fluororesin and mix, last slowly dropwise addition of acrylic acid is that the polyocarboxy acid type thickening material stirs 10～15 minutes to thorough mixing, and the emulsion that obtains is filtered, standing and reacting under vacuum condition obtains this highly effective rainproof paint.
Employed each raw material of this highly effective rainproof rainproof paint is the commercially available prod among the present invention, and pure-acrylic emulsion is a latex paint emulsion.Be applicable to multiple base material, base material is had good sticking power, have characteristics such as good mechanical stability,, high gloss good, good weathering resistance, wear resistance with the compatibility of pigment.Polycarboxylate type dispersion agent can effectively carry out homodisperse with mineral filler and pigment, and the improvement system is to the wettability of color stuffing, shorten milling time, stablize color stuffing dispersion system, prevent color stuffing flocculation, reduction loose colour, tendency such as grow dim.DA is a kind of dispersion agent that is widely used in water-borne coatings, is the polymer aqueous solution of polycarboxylate type, and it has splendid molecular weight and the molecular weight distribution that is rather narrow, and is in the emulsion paint manufacturing processed, fine with the consistency of whole coating system.Select for use the DA dispersion agent can obtain best system lacquer viscosity.After adding the DA dispersion agent, can improve the mud jacking efficient of coating, effectively suppress returning of color stuffing and slightly reach the viscosity knock-on that face is filled out slurry, thereby improve the stability in storage of coating.The dispersion agent that the present invention uses can be dispersion agent DA-01, dispersion agent DA-5016 or the dispersion agent 5040 in the dispersion agent of commercial goods.
Defoamer BA-202 is a kind of nominal particle size ACRYLIC EMULSION, it is applicable to multiple formulation for coating material, and have excellent weathering resistance, good anti-stain characteristic and wear resistance with the coating that it made, but and ultraviolet radiation resisting, timber and metallic surface are all had good sticking power.Sanitas LXE is the high-performance anticorrosion and bactericidal agent by Rhom and Hass's Development and Production, it is applicable to emulsion paint, all kinds of water-borne coatings, emulsion polymerization, also can be used for suppressing bacterium and fungi growing at production and memory print printing ink and other moisture organic products.To phenylpropyl alcohol, vinegar third, pure third and other multipolymer fabulous preservative efficacy is arranged, and fabulous compatible conformability is arranged with organic and inorganics composition in these products.Sanitas LXE to phenylpropyl alcohol, vinegar third, pure third and other multipolymer fabulous preservative efficacy is arranged, and fabulous compatible conformability is arranged with organic and inorganics composition in these products.Sanitas LXE used in the present invention can be that the trade name that Rhom and Hass produces is the sanitas of Kathon LXE, also can be the sanitas LXE that Shenzhen Haichuan Company is produced.
40% potassium hydroxide solution is used to regulate the pH value of this highly effective rainproof paint, and the pH value of rainproof paint finished product is adjusted between 7～9.The chemical name of film coalescence aid alcohol ester-12 is 2,2,4-trimethylammonium-1, and the 3-pentanediol mono isobutyrate, it can improve the film forming properties of emulsion paint, reduces the minimum film-forming temperature of emulsion paint, improves the scrub resistance of emulsion paint, improves the emulsion paint color developing.In emulsion paint, use this product, can be lowered into film temperature effectively, improve the paint film scrub resistance, improve the pigment homogeneity, have good color developing, improve paint film adhesion, reduce Alligatoring, peel off.The not hydrolysis in general alkaline medium of this film coalescence aid has good preservation stability.Under the mal-condition lower in temperature, that humidity is bigger, still have film forming properties preferably.Therefore, in emulsion paint, use this product in right amount, can improve the performance of product effectively.Acrylic acid series polyocarboxy acid type thickening material AT-06 can give moderate levelling of coating system and sagging performance, has excellent compatibility with various Emulsion Adhesives, thickening efficiency height, good rheological property.Storage and stability in use through the latex after its thickening are all good, and can satisfy the requirement of the multiple form of construction work course of processing.
Nanometer grade silica has higher surface activity, and it utilizes its surface effects, can effectively improve the hydrophobicity and the contamination resistance of paint film.Nano titanium dioxide can utilize its photocatalytic effect, thereby the anti-uv-ray that improves paint film improves the resistance to deterioration of coating with lacquer.
Beneficial effect of the present invention is, this rainproof paint utilizes the combination of water-based fluorocarbon branch and pure acrylic acid emulsion, and the adding of nanometer grade silica and Nano titanium dioxide, effectively raise the ageing resistance of paint film and have the excellent in water resistance energy, prolonged the work-ing life of paint film greatly.This highly effective rainproof paint can be used as the rainproof treatment of various building walls widely.
