70 parts；0.5 part of thickening agent；5 parts of coupling agent；75 parts of water.
Wherein, dispersant is sodium salt dispersant, and thickening agent is polyurethane thickener, and multifunctional assistant is chosen from Angus
AMP-95, coupling agent is silane coupler, and the year of hydroxyethyl cellulose is 30000cps, and wetting agent chooses the BD- from Tao Shi
405.
A kind of preparation method of high-intensity inorganic coating, comprises the following steps：
, in water, slow machine 600r/min stirs 5min, until outward appearance for A, by weight addition hydroxyethyl cellulose, rheological agent
No obvious coarse granule.
B, add multifunctional assistant so that hydroxyethyl cellulose is completely dissolved, be subsequently adding half defoamer, sodium salt dispersant,
Wetting agent and propylene glycol continue slow machine and stir.
C, input titanium dioxide and ground calcium carbonate, then stir 20min with the speed of 1400r/min, detect that its mixing is thin
Degree requires to be 45 μm.
D, to add under the rotating speed of 600r/min after silicone acrylic emulsion stirs, be subsequently adding coalescents, remaining froth breaking
Agent, potassium silicate, coupling agent, finally with thickening agent adjustment viscosity to 95KU, that is, obtain high-intensity inorganic coating.
Coating products are carried out with correlated performance detection, sample number into spectrum 7, the results are shown in Table 8, table 9.
Table 8 coating and its film ostensibly detection, the detection of film yellowing resistance
Note：1st, the detection of whiteness is carried out according to standard GB/T/T 5950-2008；The detection of covering power is according to country's mark
Quasi- GB/T1726-1979 is carried out；The detection of yellowing resistance is carried out according to standard GB/T/T 23987-2009.
2nd, the detection method of appearance of film is：Coating is applied on model, places 24h, visually observe under scattering daylight,
If smearing uniformly, no sag, growing dim, pin hole, the defects of film coating such as cracking and flaking off, being then chosen as normal.
3rd, the detection method of coating bin stability is：The sample of about 0.5L is loaded in the storage tank of good seal, in tank
Leave about 10% space, put into after sealing in (50 ± 2) DEG C thermostatic drying chamber, take out after 7 days and place at (23 ± 2) DEG C
3h, coating state before and after contrast storage.
The machinery of table 9 film and mechanics properties testing
Note：The detection of pencil hardness is carried out according to standard GB/T/T 6739-2006；The detection of adhesive force is according to country
Standard GB/T 9286-1998 is carried out；The detection of resistance to impact is carried out according to standard GB/T/T 1732-1993.
As can be seen from Table 8, according to the inventive method, by activated calcium and titanium white compound powder preparation coating, due to
In technique, the particle diameter of activated calcium and titanium dioxide, particle size distribution and the particle diameter relation of the two are defined, simultaneously in whiteness, ζ
In the indexs such as electric potential relation, oil factor relation, activated calcium and titanium dioxide are controlled it is ensured that activated calcium and titanium dioxide combine
The good deployment conditions in coating of thing, the coating being simultaneously obtained outline on whiteness, covering power, storage-stable is better than contrast
Example product；In addition in activated calcium and titanium white compound powder, activated calcium is the lightweight carbonic acid through activation processing for the surface to the present invention
Calcium, its stability is higher, and obtained coating is better than comparative example product on yellowing resistance.
As can be seen from Table 9, in the present invention due to ensure that activated calcium and titanium white compound powder in coating point
Scattered situation, and the zeta potential relation of activated calcium and titanium dioxide is defined so as to have stronger combination in coating
The chain structure of power, wherein activated calcium not only avoid the reunion in coating of activated calcium and titanium white compound powder, optimizes its point
Scattered performance, even more greatly improves in coating the active force between each group is divided, also enhances between paint film and base material simultaneously
Active force.Coating prepared according to the methods of the invention, its paint film is in the mechanical properties such as pencil hardness, adhesive force, resistance to impact
It is substantially better than comparative example product.
Finally it is to be appreciated that above example is merely to illustrate technical scheme and not limits, although reference
Preferred embodiment has been described in detail to technical scheme, it will be appreciated by those skilled in the art that can be to this
Bright technical scheme is modified or equivalent, and without deviating from the purpose and scope of the invention, it all should be covered at this
In the middle of bright protection domain.
