Description
Technical field
The invention belongs to paint field, the coating more particularly, to a kind of imitative yellow mud bar crackle metope effect and its preparation side
Method.
Background technology
Crackle metope effect coating is most original, most simple, most warm pleasant construction material, other in mountain villa in recent years
The inner-outer wall in the places such as villa, hot pot city, market is more and more widely used in covering with paint, lacquer, colour wash, etc., and gives return to primitive age field
Honourable and wireless reverie triggers the feeling that people calls to mind past sufferings and thinks over the good times.But current crackle metope effect coating many on the market all exist
The phenomenon that poor adhesive force, intensity are low, water resistance is bad, application property is difficult, crack effect is uneven, crack shape is unnatural influences
Crackle metope effect coating is in further genralrlization application on the market.
Invention content
It is an object of the present invention to be directed to the deficiencies in the prior art, a kind of imitative yellow mud bar crackle metope effect is provided
The coating of fruit.
For this purpose, the above-mentioned purpose of the present invention is achieved through the following technical solutions:
A kind of coating of imitative yellow mud bar crackle metope effect, which is characterized in that the imitative yellow mud bar crackle metope effect
Coating includes:
Remaining gathers together enough mass percent as 100% with water.
In order to obtain further technique effect, the present invention can also use technical solution further below:
Preferably, the self-crosslinking pure-acrylic emulsion is formed by acrylic ester monomer and acrylic acid copolymer.
Preferably, solid part of the self-crosslinking pure-acrylic emulsion is 47~49%wt.
Preferably, the yellow mud bar is the yellow clay that main component is aluminium oxide and iron oxide.
Preferably, the preservative is isothiazolinone and its derivative.
Preferably, the quartz sand be 10~20 mesh, 20~40 mesh and one kind in 120~180 mesh natural siliceous sands or
Several combination of person.
Preferably, the crackle agent is the one or several kinds in superfine alumina silicate, zinc stearate and aerosil
Combination.
Preferably, the thickener is that association type alkali swollen thickener, polyurethane thickener and sodium carboxymethylcellulose increase
One or several kinds of combinations in thick dose.
Another object of the present invention is, for the deficiencies in the prior art, provides a kind of imitative yellow mud bar and splits
The preparation method of the coating of line metope effect.
For this purpose, the above-mentioned purpose of the present invention is achieved through the following technical solutions:
A kind of preparation method of the coating of imitative yellow mud bar crackle metope effect, the preparation method provide foregoing imitative
The coating of yellow mud bar crackle metope effect, and prepare in accordance with the following steps:
Water is put into painting cylinder, pre-gelatinized tapioca starch, xanthans and preservative is added in airborne dust formula under stirring, and
With 1500~2000rpm/min, 15~20min of high speed dispersion, it is made fully to be dissolved into uniform, transparent glue, yellow mud is added
Bar, quartz sand and straw be mixed evenly, self-crosslinking pure-acrylic emulsion and crackle agent is then added with 1500~2000rpm/
Min high speed dispersions are eventually adding thickener adjustment viscosity to uniform.
The present invention is prepared for one kind using natural materials such as yellow mud bar, straw, quartz sand, pre-gelatinized tapioca starch, xanthans
The coating of imitative yellow mud bar crackle metope effect, the coating is environmentally protective, easily batch scrape, application property is good, to the strong adhesive force of base material,
Crackle clean mark is naturally, can be widely applied to the covering with paint of metope inside and outside leisure farm, foot bath city, amusement club etc., product tool
There are functions, the market prospects such as breathing damping, fire protection flame retarding, the noise abatement of drop sound, insulation fine.
Specific implementation mode
The present invention is described in further detail with reference to specific embodiment.
Embodiment 1
Composition:
Water is first put into painting cylinder, airborne dust formula is added pre-gelatinized tapioca starch, xanthans and preservative and exists under stirring
15~20min of high speed dispersion under 1800 rpm/min makes it fully be dissolved into uniform, transparent glue, and yellow mud bar, quartz is added
Sand, straw are mixed evenly, and self-crosslinking pure-acrylic emulsion, crackle agent is added and high speed dispersion is uniform at 1800rpm/min.
Then thickener is added and adjusts viscosity, is packed after qualified.
Embodiment 2
Composition:
The preparation method of the coating of imitative yellow mud bar crackle metope effect in embodiment 2 and the preparation method in embodiment 1
It is identical.
Embodiment 3
Composition:
The preparation method of the coating of imitative yellow mud bar crackle metope effect in embodiment 3 and the preparation method in embodiment 1
It is identical.
The obtained imitative yellow mud bar crackle metope effect coating of the embodiment of the present invention 1 to 3 is split with certain brand on the market
Line metope effect coating is compared, and test result is as follows for coating property shown in table:
By the above test result it can be found that the coating of imitative yellow mud bar crackle metope effect provided by the present invention is with good
Good workability, the adhesion strength performance under standard state and after immersion show it is excellent, it is resistance under 96h water resistance tests
Water effect is fabulous, and the performance under the test of 48h alkali resistances is excellent, and its appearance of film crackle clear and natural is uniform, therefore, this
