Description
Technical field
The present invention relates to building coating technical field, more particularly to a kind of system of high durable environment-friendly water-based building external paint
Preparation Method and preparation method thereof.
Background technology
Exterior coating not only plays a protective role to building, also with decoration and beautification function.In recent years, as society enters
Step, Architectural Paint in China field quickly grows, the requirement of people's External Wall coating also more and more higher, high-performance, multi-functional water
Property environmental protection turn into exterior coating developing direction.
In domestic market, the good solvent type exterior wall coating of easy construction, film performance also takes up leading position, molten
The shortcoming of formulation coating is containing VOC and free formaldehyde, it is difficult to meet the requirement in terms of environmental protection.And water-based exterior wall paint is as again
Close styrene-acrylic emulsion or modified polyvinylalcohol veriety is although nontoxic, harmless, filming performance is excellent, but easily aging occur and make
There are the phenomenons such as loss of gloss, colour fading, peeling, peeling, cracking, efflorescence in film.Addition of the nano material in coating can improve film
Physical and chemical performance, and ultraviolet light can be shielded, reach the effect for the weatherability for improving coating, have become research heat
Point.However, nano material is directly applied in coating, there is following defect：Particle surface energy is high, easily reunites, with base-material
Adhesion is poor, easily forms boundary defect, causes film performance and presentation quality to decline, durability is low.
The content of the invention
The object of the invention be exactly in order to make up the defect of prior art there is provided it is a kind of uniform, stably, it is superior in quality, durable
The preparation method of high environment-friendly water-based building external paint.
The present invention is achieved by the following technical solutions：
A kind of preparation method of high durable environment-friendly water-based building external paint, comprises the steps：
（1）By 3-5 parts of titanium dioxides, 4-6 parts of talcum powder and 10-15 parts of mica powders mix merga pass grinder be ground to 400 mesh with
Under, obtain filler powder；
（2）15-25 parts of poly-vinyl alcohol solutions are added into 85-95 DEG C of stirring 10-15min in container, 3-5 parts of calcium nitrate are then added
Solution is well mixed, and being slow added into ammonium dibasic phosphate solution makes calcium-phosphorus ratio be 1.6-1.67, and pH is adjusted into 10-11 and in 40-
60 DEG C of stirring 4-6h, are then slowly added into 0.1-0.15 parts of silane coupling As -151 and the mixed liquor of 3-5 parts of absolute ethyl alcohols, rise
Temperature continues to stir 4-6h to 70-80 DEG C, and 30-40 parts of styrene-acrylic emulsions are added after cooling and are well mixed, coating base fluid is obtained；
（3）By step（1）The filler powder of gained adds step（2）Stirring mixing is equal in mixer in the coating base fluid of gained
It is even, 0.05-0.1 parts of mould inhibitors and 5-10 parts of water are then added, high durable environment-friendly water-based external wall is produced after grinding, filtering and is applied
Material.
It is preferred that, the concentration of the calcium nitrate solution is 0.1-0.15mol/L.
It is preferred that, the concentration of the ammonium dibasic phosphate solution is 0.1-0.15mol/L.
It is preferred that, the solid content of the poly-vinyl alcohol solution is 3-5%.
It is preferred that, the solid content of the styrene-acrylic emulsion is 40-60%.
It is preferred that, the step（3）Middle stirring condition is：40-50 DEG C of whipping temp, mixing time 0.5-1h.
It is an advantage of the invention that：
The present invention generates nanometer hydroxyl by the way that calcium nitrate solution and ammonium dibasic phosphate solution are blended in into poly-vinyl alcohol solution situ
Base apatite, so as to obtain uniform nanometer hydroxyapatite/polyvinyl alcohol doping system in situ, improves single polyvinyl alcohol
The mechanical property and weatherability of system；Again by adding the ethanol solution of silane coupling A -151, silane coupler into system
A-151 is hydrolyzed and is grafted to nanometer hydroxyapatite surface, the hydrophobically modified in situ to nanometer hydroxyapatite is realized, so as to assign
The hydrophobicity for giving nanometer hydroxyapatite/polyvinyl alcohol system good.After the raw materials such as the system and styrene-acrylic emulsion, filler are mixed
Exterior coating is prepared, obtained product has excellent water resistance and weatherability, durability degree is high, and service life is long, and uniformly,
Stable, presentation quality is good, environmental protection.
Embodiment
A kind of preparation method of high durable environment-friendly water-based building external paint, comprises the steps：
（1）3 parts of titanium dioxides, 4 parts of talcum powder and 10 parts of mica powders are mixed into merga pass grinder to be ground to below 400 mesh, obtained
Filler powder；
（2）15 parts of poly-vinyl alcohol solutions are added into 85 DEG C of stirring 10min in container, 3 parts of calcium nitrate solution mixing are then added equal
