Tradition is all the coating for organic solvent, and the contaminative of this coating is serious, therefore, now everybody big area bring into use water-borne coatings, and for exterior coating, need the wherein important technological problems solved to be heat insulation, but its heat-proof quality of existing water-borne coatings is all not good enough.
Summary of the invention
The object of this invention is to provide a kind of preparation method of water-borne heat-insulating priming paint, utilize preparation method of the present invention, its technique is simple, and the heat-proof quality of the water-borne heat-insulating priming paint of preparation is good.
For achieving the above object, the preparation method of water-borne heat-insulating priming paint comprises:
(1) auxiliary agent taking the ceramic fine bead of 22%-28%, the deionized water of 20%-25%, the filler of 8%-12% and 5%-7% stirs under the rotating speed of the temperature 400 ~ 800r/min of 70-80 DEG C;
(2) the machine silicon-ACRYLIC EMULSION taking 30%-40% joins in step (1), and reacts 20-40min while stirring in the water-bath of 80-100 DEG C;
(3) take the defoamer of 0.2%-0.5%, the sanitas of 0.1%-0.5%, the thickening material of 0.5%-0.9% join in step (2), under 400 ~ 800r/min speed conditions, stir 5 ~ 10 minutes; Obtain water-borne heat-insulating priming paint after filtration;
Wherein, the internal diameter of ceramic microsphere is less than 3 μm, and unit weight should be less than 180kg/m
3, above-mentioned weight percent is all weight percentage.
Further, the weight percent of each raw material is:
Organosilicon-ACRYLIC EMULSION 35%
Ceramic fine bead 25%
Deionized water 22.6%
Filler 10%
Auxiliary agent 6%

Further, filler is the one in talcum powder, dicalcium powder, kaolin, process white.
Further, described auxiliary agent is film coalescence aid, and described film coalescence aid is alcohol ether solvent or the cruel kind solvent of alcohol.
Further, described defoamer is polysiloxane-polyether copolymer, and described sanitas is nitrite, described thickening material be association type gather in the cruel thickening material of ammonia one or both.
The invention has the beneficial effects as follows: owing to present invention employs special ceramic microsphere as basic raw material, organosilicon-ACRYLIC EMULSION is added in ceramic microsphere, this material is that the small ceramic particle be suspended in gel by some is formed, this just makes the hole diameter in material very little, air molecule in pore then loses free-pouring ability, but be relatively attached on air vent wall, be at this moment equivalent to be in material be similar to vacuum state.Ceramic microsphere makes material internal contain extremely many transmitting interfaces and microscopic scatterers simultaneously, reflection and scattered radiation heat, and organosilicon-ACRYLIC EMULSION, filler and ceramic microsphere all have effect of heat insulation.Therefore, make the heat-proof quality of this priming paint good.Processing step of the present invention is few, and technique is simple, and cost is low.
