Hereinafter, with reference to the drawings with respect to the manufacturing method of the wood stain of the present invention will be described in detail. 1 is a schematic flowchart of a process for producing a wood stain using the wood stain composition of the present invention.

Referring to FIG. 1 , as step S1, the compound represented by Formula 1, the compound represented by Formula 2, and the compound represented by Formula 3 are mixed in an organic solvent to prepare a wood protection solution.

[Comparative Example 6: Wood Stain Manufacturing]

The wood stain of Comparative Example 6 was prepared according to the following process according to the composition described in Table 1 above.

First, the raw materials 6 and 9 were put into the raw material 4 in a high-speed stirrer, and the state was checked by stirring at 1000-1500 rpm for 30 minutes.

After that, the raw materials 7, 11 and 12 were added to the formulation and stirred at 500 to 800 rpm. Thereafter, 4 weights of Synthro-comp 60B from SYNTHRON as a synthetic surfactant not described in Table 1 was added to the formulation, followed by stirring at 800 to 1000 rpm for 20 minutes to check the state.

Then, water was added to the formulation at 7 m/s and stirred at 1000 to 1500 rpm for 20 minutes to confirm the state.

Finally, raw material 8 and raw material 2 were added and stirred at 400 to 700 rpm to prepare a wood stain according to the present invention.

[Test Example 1: Confirmation of the wood stain formulation of Example 1, Comparative Example 1, and Comparative Example 2]

2 to 3 are photographs of the wood stains of Example 1 and Comparative Example 6. 2 is a photograph of the wood stain of Example 1, and FIG. 3 is a photograph of the wood stain of Comparative Example 6. In the wood stain prepared according to the present invention, oil is uniformly dispersed even after 5 hours at room temperature, and oil-min It was possible to visually confirm that it had formulation stability, such as no sediment at the bottom and no color separation, because it provided stability to separation between the bodies and no sedimentation of pigments.

3 is a photograph of the wood stain of Comparative Example 6, and after 2 hours at room temperature using a synthetic surfactant, sedimentation of the pigment occurred, and it was confirmed visually that the sediment was confirmed on the floor.

Through these results, when the oil is dispersed after first mixing the wood protection liquid in which the wood protection component is well mixed with the organic solvent, the dispersion stability of the oil and the oil- It can be confirmed that wood stains having separation stability between powders are produced.

[Test Example 2: Confirmation of coloring ability of wood stain]

The coloring ability of the wood stains of Example 1, Comparative Example 1 and Comparative Example 2 was confirmed.

First, each wood stain was brush-painted, dried, and washed (using cloth) was repeated a total of two times, and the amount of painting was set to be within the range of 5 to 6 m2/L.

In addition, the drying conditions were dried for 12 hours at room temperature 15 to 20 degrees Celsius after the first coating, and then dried at room temperature 15 to 20 degrees Celsius for 24 hours after the second coating.

After the wash operation, the degree of coloring was relatively compared, and when the result of Comparative Example 1 was 100, in Example 1, 120 and in Comparative Example 2, a result of 130 was obtained.

In terms of simple results, the best coloring power was shown in the example of using the rosin resin alone of Comparative Example 2, but the coloring ability optimization effect according to the present invention was confirmed considering that the coating film was somewhat hard and undesirable.

[Test Example 3: Confirmation of sedimentation property of wood stain]

The settling properties of the wood stains prepared in Example 2 and Comparative Example 3 were confirmed.

As a result of comparatively comparing the degree of sedimentation of the pigment after 12 hours had elapsed, when Example 2 was 100, Comparative Example 3 corresponded to 60.

From these results, in the case of Example 2, in which the bentonite powder is directly injected and dispersed, compared to Comparative Example 3, in which the paste is added, the dispersion time is shortened as well as the stirring and low-speed dispersion is possible, and the sedimentation rate of the pigment is also slow could check

[Test Example 4: Confirmation of physical properties of wood stain]

The properties of the wood stains prepared in Example 3, Comparative Example 4, and Comparative Example 5, respectively, were checked for drying properties, surface properties after drying, and differences in properties in containers.

First, each wood stain was brush-painted, dried, and washed (using cloth) was repeated a total of two times, and the amount of painting was set to be within the range of 5 to 6 m2/L.

In addition, the drying conditions were dried for 12 hours at room temperature 15 to 20 degrees Celsius after the first coating, and then dried at room temperature 15 to 20 degrees Celsius for 24 hours after the second coating.

In addition, the state in the container was checked at intervals of 1 to 2 hours.

As a result, the quick-drying performance was faster in Comparative Examples 4 and 5 in which the extender was added than in Example 3 in which the extender was not added, but the surface condition was visually observed in Comparative Examples 4 and 5. It was confirmed that the color clarity of Example 3 was the most excellent as the appearance was more cloudy than that of Example 3.

Furthermore, it was confirmed that not only some lumps were generated in Comparative Examples 4 and 5, in which the extender was added, but also the sedimentation rate was faster than in Example 3 due to specific gravity in terms of the difference in properties in the container.

From these results, when the commonly used extender pigments are used as in Comparative Examples 4 and 5, the surface dries quickly, but the difference in color clarity is remarkable. It can be said that it is superior to Comparative Example 4 and Comparative Example 5.

From these results, the present invention can contain a large amount of oil without containing a synthetic surfactant, and can not only uniformly disperse a large amount of oil without expensive equipment such as a high pressure emulsifier, but also improve the separation stability of oil-powder. knew it could be
