The industry using wood is continuously developing, and the paint which is applied to the wood is continuously developing. Stain is used to protect the appearance of the wood. Stain can improve the durability of the wood, protect the wood and realize various colors.
The reduction of volatile organic compounds (VOC) is becoming an issue in relation to the environmental problems that have recently emerged. In this regard, many paint manufacturers have begun to release stain products that have reduced VOCs, and many of Mercury's products are being introduced in this process. However, existing aqueous stains have various problems such as extremely limited durability and not suitable for wood containing tannin.
On the other hand, oily stain is an oily liquid that acts as a coloring agent and finishing agent for the semi-finished wood surface.
For existing oily stain, it is required to meet the TVOC standard (less than 300 g / L) in 2015, and when the specific gravity is 1, the solid content is more than 70% or the sum of the solid content and the solvent content is 70 %.
Due to the nature of oily stain, it is necessary to penetrate the wood to protect the wood. However, when the solid content is high, the permeability to the wood is lowered and the durability is lowered, and when the solvent is mixed, the properties of the oily stain are deteriorated.

The present invention provides a method for manufacturing an oily stain that can improve the inherent physical properties of oily stain by lowering the VOC content of oily stain by increasing the solid content using water in the production of oily stain and improving the permeability when applied to wood can do.
Hereinafter, preferred embodiments of the present invention will be described in detail. The terms and words used in the present specification and claims should not be construed as limited to ordinary or dictionary meanings and should be construed in accordance with the technical meanings and concepts of the present invention.
The embodiments described herein are preferred embodiments of the present invention and are not intended to represent all of the technical ideas of the present invention, so that various equivalents and modifications may be substituted for them at the time of application of the present invention.
Hereinafter, a method for producing oily stain according to the present invention will be described in detail.
First, an alkyd resin, a defoaming agent and an anti-settling agent are mixed with stirring (first step).
As the alkyd resin used in the present invention, it is preferable to use a long oily alkyd resin having 55 to 65% of whey expressed by the following formula (1), which has a good permeability to wood and is suitable for waterproofing after drying.
As the alkyd resin used in the present invention, a long oil-based alkyd resin of a high oil content can be used to facilitate the permeability to wood, thereby forming a coating film.
In one embodiment of the present invention, the alkyd resin is preferably used in an amount of 20 to 40 parts by weight based on the final combination.
If the alkyd resin is used in an amount exceeding 40 parts by weight based on the final blend, the viscosity of the oil-based stain may increase and the workability may be deteriorated.
As the defoaming agent in the present invention, silicon type defoaming agents and non-silicon type defoaming agents known in the art can be used without limitation.
In the present invention, the defoaming agent may be used in an amount of 0.5 to 1.5 parts by weight based on the final formulation to remove bubbles during high-speed stirring.
In the present invention, when the coloring agent is added to the oily stain by using the anti-settling agent, it is possible to prevent color discrepancy due to sedimentation of the pigment.
In the present invention, the anti-settling agent may be bentonite, polyamide wax, silica, or the like, but is not limited thereto.
In one embodiment of the present invention, the anti-settling agent is preferably used in an amount of 0.3 to 1 part by weight based on the final combination.
When the anti-settling agent is used in an amount less than 0.3 part by weight based on the final formulation, the settling property may be lowered and the viscosity may be lowered. When the anti-settling agent is used in excess of 1 part by weight based on the final formulation, the settleability is good, The workability may be relatively lowered.
In one embodiment of the present invention, the step of stirring the alkyd resin, defoamer, and anti-settling agent is preferably performed at 1000 to 1500 rpm for 20 to 40 minutes.
The anti-settling agent may be completely dispersed by performing the alkyd resin, antifoaming agent and anti-settling agent at 1000 to 1500 rpm for 20 to 40 minutes.
Next, a disinfectant, an insect repellent, and an anti-film agent are added to the formulation and stirred (second step).
The sterilizing effect can be imparted to the wood by using the antifungal agent in the production of the oily stain according to the present invention.
Examples of the sterilizing agent include IPBC (3-iodo-propynyl-butylcarbamate), OIT (2-n-octyl-4-isothiazolin-3-one), propiconazole, It is needless to say that antifungal agents can be used.
In one embodiment of the present invention, the antifungal agent is preferably used in an amount of 0.5 to 1 part by weight based on the final formulation.
According to the present invention, the use of an insect repellent in the production of oily stain can prevent the wood from being damaged.
As the insecticide, insecticides for termite resistance, for example, permethrin and the like may be used, but other kinds of insecticides may be used.
In one embodiment of the present invention, the repellent is preferably used in an amount of 0.5 to 1 part by weight based on the final combination.
By using the anti-filming agent in the production of the oily stain according to the present invention, it is possible to prevent the formation of the oily stain film and improve the storage stability of the oily stain.
Examples of the anti-film agent used in the present invention include, but are not limited to, methyl ethyl ketoxime.
In one embodiment of the present invention, the anti-filming agent is preferably used in an amount of 0.1 to 0.3 parts by weight based on the final combination.
Next, a water-in-oil type surfactant is added to the mixture, stirred at 800 to 1000 rpm for 10 to 20 minutes, then mixed with water at 1 to 7 m / s, and stirred at 1000 to 1500 rpm for 20 to 30 minutes Step 3).
According to the present invention, VOC can be reduced and the content of solid content can be increased by using water in the production of oily stain.
Therefore, in order to inject water into the oily stain, the water-in-oil surfactant is first added, and water is added to the oily stain.
The water-in-oil type surfactant, such as a polysaccharide resin, which can be used in the present invention, acts as an intermediate capable of water-solubilizing the alkyd resin by water.
In one embodiment of the present invention, the water-in-oil type surfactant is preferably used in an amount of 3 to 6 parts by weight based on the final combination.
When the water-in-oil surfactant is used in an amount less than 3 parts by weight based on the final combination, layer separation may occur upon water-solubilization, and if the water-in-oil surfactant is used in excess of 6 parts by weight based on the final combination, There is a problem that the unit price is increased.
It is preferred that the water-in-oil surfactant is added to the compound of the third step and the mixture is stirred at 800 to 1000 rpm for 10 to 20 minutes, and then water is added to the compound at 1 to 7 m / s. As described above, when the oil-based stain is produced, the volatilized solvent can be reduced by introducing water.
When water is added at a proper rate of 1 to 7 m / s after the water-in-oil surfactant is added to the compound of the third step, the water-solubilization is stabilized and layer separation occurs in which the alkyd resin and water are separated during the operation It does not.
In the third step, the remaining amount of water is added so that the final blend is 100 parts by weight, and then the mixture is stirred at 1000 to 1500 rpm for 20 to 30 minutes to stabilize the layer so that the layer separation does not occur.
Thereafter, a dryer and a solvent are added to the above-mentioned blend and stirred (fourth step).
In the present invention, since hardening is not performed using only alkyd resin, the oily stain is cured using a dryer.
In one embodiment of the present invention, the dryer can be an oxidative dryer selected from the group consisting of cobalt, manganese, barium and cesium and a polymerizable dryer selected from the group consisting of lead, zinc, calcium and zirconium .
The oxidizing-type dryer rapidly forms a dried coating film on the surface of the coating film of the oil-based stain to prevent oxygen from diffusing into the coating film.
The polymerization type drier makes it possible to form a uniform dry film although the oxidation rate is not fast.
The dryer is preferably used in an amount of 2 to 3 parts by weight with respect to the final combination, and it is preferable to use an oxidative dryer and a polymerizable dryer in combination.
Examples of the solvent include aliphatic hydrocarbon solvents commonly used in oily stains, such as ISU-D SOL 150, 180 and 200, and EXXOL D40 and D80 of Exxon Mobil.
