Performance detection is closed, sample number into spectrum 6 the results are shown in Table 8, table 9.
Comparative example
Using the embodiment 1 of patent of invention CN 105542603A：
A kind of high-intensity inorganic coating, is made of the raw material of following parts by weight：
0.5 part of hydroxyethyl cellulose；3 parts of rheological agent；0.5 part of multifunctional assistant；2.5 parts of antifoaming agent；2 parts of dispersant；Profit
1.5 parts of humectant；1 part of propylene glycol；40 parts of titanium dioxide；65 parts of powdered whiting；35 parts of silicone acrylic emulsion；1 part of coalescents；Potassium silicate
70 parts；0.5 part of thickener；5 parts of coupling agent；75 parts of water.
Wherein, dispersant is sodium salt dispersant, and thickener is polyurethane thickener, and multifunctional assistant is chosen from Angus
AMP-95, coupling agent are silane coupling agent, 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, includes the following steps：
A, it is added in hydroxyethyl cellulose, rheological agent to water by weight, slow machine 600r/min stirs 5min, until appearance
Without apparent coarse granule.
B, multifunctional assistant is added makes hydroxyethyl cellulose be completely dissolved, be then added half antifoaming agent, sodium salt dispersant,
Wetting agent and propylene glycol continue slow machine and stir evenly.
C, titanium dioxide and powdered whiting are put into, 20min is then stirred with the speed of 1400r/min, it is thin to detect its mixing
Degree requires to be 45 μm.
D, after with addition silicone acrylic emulsion stirs evenly under the rotating speed of 600r/min, coalescents, remaining defoaming is then added
Agent, potassium silicate, coupling agent finally adjust viscosity to 95KU to get to high-intensity inorganic coating with thickener.
Correlated performance detection is carried out to coating products, sample number into spectrum 7 the results are shown in Table 8, table 9.
8 coating of table and its film ostensibly detection, the detection of film yellowing resistance
Note：1, GB/T 5950-2008 are carried out according to national standards for the detection of whiteness；The detection of covering power is marked according to country
Quasi- GB/T1726-1979 is carried out；GB/T 23987-2009 are carried out according to national standards for the detection of yellowing resistance.
2, the detection method of appearance of film is：Coating is applied on model, places for 24 hours, is visually observed in the case where scattering daylight,
If smearing uniform, no sag, pin hole, the defects of film coating such as cracks and flakes off at floating, then is chosen as normal.
3, the detection method of coating bin stability is：The sample of about 0.5L is fitted into the storage tank of good seal, in tank
It there are about 10% space, is put into after sealing in (50 ± 2) DEG C thermostatic drying chamber, takes out after 7 days and placed at (23 ± 2) DEG C
3h, the front and back coating state of comparison storage.
The machinery and mechanics properties testing of 9 film of table
Note：GB/T 6739-2006 are carried out according to national standards for the detection of pencil hardness；The detection of adhesive force is according to country
Standard GB/T 9286-1998 are carried out；GB/T 1732-1993 are carried out according to national standards for the detection of impact resistance.
As can be seen from Table 8, according to the method for the present invention, the coating prepared by calcium activated and titanium white compound powder, due to
The grain size relationship of the grain size of calcium activated and titanium dioxide, size distribution and the two is defined in technique, while in whiteness, ζ
Calcium activated and titanium dioxide are controlled in the indexs such as electric potential relation, oil factor relationship, it is ensured that calcium activated and titanium dioxide combination
Object good deployment conditions in coating, while coating obtained outline on whiteness, covering power, storage-stable is better than comparison
Example product；In addition for the present invention in calcium activated and titanium white compound powder, calcium activated is lightweight carbonic acid of the surface Jing Guo activation process
Calcium, stability is stronger, 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 point of calcium activated and titanium white compound powder in coating
Situation is dissipated, and the zeta potential relationship of calcium activated and titanium dioxide is defined, makes it that there is stronger combination in coating
The chain structure of power, wherein calcium activated not only avoids the reunion of calcium activated and titanium white compound powder in coating, optimizes its point
Performance is dissipated, even more greatly improves the active force in coating between each component, while also enhancing between paint film and base material
Active force.Coating prepared according to the methods of the invention, paint film is in the mechanical properties such as pencil hardness, adhesive force, impact resistance
It is substantially better than comparative example product.
Finally it is to be appreciated that above example is only used to illustrate the technical scheme of the present invention and is not limited, although reference
Technical scheme of the present invention is described in detail in preferred embodiment, it will be appreciated by those skilled in the art that can be to this hair
Bright technical solution is modified or replaced equivalently, and without departing from the purpose and scope of the invention, should all be covered in this hair
In bright protection domain.
