Description

Technical Field

[0001] The present application relates to the technical field of wooden furniture surface treatment agents, and in particular to a furniture wood surface treatment agent and a preparation method thereof. Background Art

[0002] Pine furniture is more environmentally friendly than other furniture, especially since many painted pieces currently contain high levels of formaldehyde. Due to its elasticity and breathability, even painted pine furniture has significantly lower formaldehyde levels than other furniture. Unpainted pine furniture, on the other hand, retains its original character, natural grain, and natural beauty, without any pollution. The unique grain of pine wood, with its distinct growth rings and wood texture, creates a natural and warm atmosphere, adding vitality to a home and is currently experiencing increasing market demand.

[0003] At present, after pine furniture is treated with existing surface treatment agents, the original clear and simple wood grain, wood color, texture, etc. of the pine furniture will deteriorate. It is necessary to develop a surface treatment agent to improve the texture clarity and three-dimensional sense of pine furniture. Summary of the Invention

[0004] In order to improve the texture clarity and three-dimensional effect of pine furniture, the present application provides a furniture wood surface treatment agent and a preparation method thereof.

[0005] In the first aspect, the present application provides a furniture wood surface treatment agent, which adopts the following technical solution:

[0006] A furniture wood surface treatment agent comprises the following raw materials in parts by mass: 74-80 parts of acetates, 14-18 parts of ethyl esters, and 9.5-10.5 parts of ethanol. The surface treatment agent is applied by brush on the surface of wooden furniture products.

[0007] By adopting the above technical solution, the various components in the furniture wood surface treatment agent of this application play different roles and work synergistically to enhance the wood's texture clarity and three-dimensional effect. Acetates dissolve impurities and stains on the wood surface, leaving the surface cleaner and smoother. Furthermore, acetates can undergo physical adsorption with ethanol and ethyl esters, enhancing the adhesion of the surface treatment agent to the wood surface. Ethyl esters improve the fluidity and wettability of the surface treatment agent, making it easier to evenly apply the surface treatment agent to the wood surface. Ethanol causes the plant fibers on the wood surface to expand, raising the wood's burrs and making the texture more prominent, thereby enhancing the wood's texture clarity and three-dimensional effect. If the amount of ethanol added is too little, the improvement in texture clarity is not significant. If the amount of ethanol added is too much, the burrs will be raised, but the raised burrs will become brittle and will powder with a touch, resulting in poor texture clarity and a reduced three-dimensional effect. By precisely controlling the amount of ethanol added and the residence time of the surface treatment agent on the wood surface, the appearance of the wood can be effectively improved, giving it better texture clarity and three-dimensional effect.

[0008] Preferably, the acetate ester is one or more of methyl acetate, sec-butyl acetate, isopropyl acetate, and methylcyclohexyl acetate.

[0009] Preferably, the acetate is a composition of sec-butyl acetate, isopropyl acetate, and methylcyclohexyl acetate in a mass ratio of 5:1-3:2-5.

[0010] By adopting the above technical solution, in the furniture wood surface treatment agent of the present application, the acetate ester used is one or more of methyl acetate, sec-butyl acetate, isopropyl acetate, and methylcyclohexyl acetate. These acetate ester components all have the following effects and synergistic effects: Acetate esters can dissolve impurities and stains on the wood surface, making the surface cleaner and smoother. Acetate esters can effectively wet the wood surface, making it easier for the surface treatment agent to be evenly applied to the wood surface and increasing the contact area between the surface treatment agent and the wood surface. Different acetate ester components have different volatilization rates. By adjusting the ratio of different acetate esters, the volatilization rate and drying time of the surface treatment agent can be controlled, so that the wood surface treatment agent remains on the wood surface for an appropriate period of time. The synergistic effect of these acetate ester components and ethanol is to improve the clarity and three-dimensional texture of the wood by jointly affecting the wettability and volatilization rate of the surface treatment agent.

[0011] Preferably, the boiling point of the ethyl esters is 75-185°C.

[0012] Preferably, the ethyl esters include any one or more combinations of ethyl acetate, ethyl formate, ethyl propionate, and ethyl acetoacetate.

[0013] Preferably, the ethyl esters are a composition of ethyl acetate, ethyl propionate and ethyl acetoacetate in a mass ratio of 8:1-3:2-4.

[0014] By adopting the above-mentioned technical solution, these ethyl ester components have the following effects and synergistic effects in the furniture wood surface treatment agent of the present application: Solvent effect: Ethyl esters can dissolve grease and stains on the surface of wood, making the surface cleaner. Wetting effect: Ethyl esters have good wettability and can effectively wet the surface of wood, making it easier for the surface treatment agent to adhere evenly to the surface of wood. Rapid volatilization: Ethyl esters have a faster volatilization rate. By controlling the amount and proportion of ethyl esters added, the volatilization rate of the surface treatment agent can be adjusted and the drying time of the coating can be accelerated. The synergistic effect of ethyl ester components with acetates and ethanol can enhance the clarity and three-dimensional sense of the wood texture, thereby improving the appearance and performance of the wood.

[0015] Preferably, the ethanol is industrial ethanol, and the volume concentration of ethanol is 95%.

[0016] Preferably, the surface treatment agent is brushed on the surface of the furniture wood product for a residence time of 22-24 minutes, and then the residual surface treatment agent on the surface of the furniture wood product is blown away with an air gun.

[0017] By employing this technical solution and precisely controlling the residence time of the surface treatment agent on the wood surface, the clarity and three-dimensionality of the wood's texture can be adjusted to achieve optimal results. Blowing away residual surface treatment agent with an air gun: Using an air gun to blow away any remaining surface treatment agent from the surface of wood furniture products removes excess surface treatment agent, ensuring that raised burrs on the wood surface are no longer damaged, thereby enhancing the clarity and three-dimensionality of the wood's texture. This operation effectively improves the appearance of the wood, giving it greater texture clarity and three-dimensionality while maintaining the smoothness and finish of the wood surface, enhancing the texture and aesthetics of the wood furniture product.

[0018] Preferably, the furniture wood product is a furniture pine wood product.

[0019] By adopting the above technical solution, the pine wood board has a unique texture, obvious annual rings and wood feel, which can bring a natural and warm atmosphere and make the home more vital. After being treated with the surface treatment agent of the present application, the unique texture of the pine wood is more prominent, the three-dimensional sense is stronger, and it is more attractive.

[0020] In a second aspect, the present application provides a method for preparing a furniture wood surface treatment agent, which adopts the following technical solution: a method for preparing a furniture wood surface treatment agent, using the raw materials of the above-mentioned furniture wood surface treatment agent, comprising the following steps:

[0021] Acetates, ethyl esters and ethanol are mixed according to their mass parts, stirred at a stirring rate of 100-150 r / min for 3-5 min, and allowed to stand to obtain a furniture wood surface treatment agent.

[0022] By adopting the above-mentioned technical solution, the present application precisely controls the amount of ethanol added and the residence time of the surface treatment agent on the wood surface. The furniture wood surface treatment agent of the present application can effectively improve the appearance of the wood, giving it better texture clarity and three-dimensional sense, and can maintain the strength and stability of the wood, thereby improving the quality and decorative effect of the product.

[0023] In summary, the beneficial technical effects of this application are:

[0024] 1. Improve the clarity of wood texture: By adding an appropriate amount of ethanol to the surface treatment agent, the plant fibers on the wood surface can expand, causing the burrs to rise, thereby making the wood texture clearer and more distinct. The amount of ethanol added is precisely controlled to achieve the best effect, significantly improving the clarity of the wood texture.

[0025] 2. Enhance the three-dimensional effect of wood: After the surface texture of wood is highlighted, it can increase the three-dimensional effect of wood. The appropriate addition of ethanol can make the texture convex, further enhancing the texture and layering of wood products.

[0026] 3. Maintain the strength and stability of wood: By precisely controlling the amount of ethanol added and avoiding excessive addition that causes the burrs to become brittle, the strength and stability of the wood can be maintained, increasing the service life of the product.

[0027] 4. Improve the appearance quality of wood: Accurately control the amount of ethanol added and the residence time of the surface treatment agent on the wood surface to make the wood surface obtain uniform color and gloss, thereby improving the appearance quality and decorative effect of the product.

[0073] Performance Testing

[0074] Pine wood boards with the same texture were selected and cut into 48 pieces of 10cmX10cm boards (3 pieces were kept as blank control samples). After surface polishing and cleaning, they were divided into 15 groups, with 3 pieces in each group. The boards were brushed with the surface treatment agents and methods in Examples 1-7 and Comparative Examples 1-8, respectively. After standing for 5 hours, the boards were gently wiped 3 times with a dust-free soft cloth by the same person. Three experts with rich industry experience were invited to observe the blank control samples and treated samples respectively, and score them according to the identification criteria in Table 1. The average score was taken. The results are shown in Table 2.

[0077] Table 2

[0078]

[0079]

[0080] In combination with Examples 1-7 and Table 2, it can be seen that the furniture wood surface treatment agent prepared in the present application is brushed on the surface of the furniture pine product for a residence time of 22-24 minutes, and then the residual surface treatment agent on the surface of the furniture wood product is blown clean with an air gun. By precisely controlling the amount of ethanol added and the residence time of the surface treatment agent on the wood surface, the appearance of the wood can be effectively improved, giving it better texture clarity and three-dimensional effect.

[0081] Combining Example 7 with Comparative Examples 1-4 and Table 2, it can be seen that precisely controlling the amount of ethanol added significantly impacts the texture clarity and three-dimensionality of the final pine furniture product. Ethanol can cause the plant fibers on the wood surface to expand, raising the wood burrs and making the texture more prominent, thereby improving the texture clarity and three-dimensionality of the wood. When the amount of ethanol added is too little, the improvement in texture clarity is not significant. When the amount of ethanol added is too much, the burrs are raised, but the raised burrs become brittle and will powder with a touch, resulting in poor texture clarity and a reduced three-dimensionality.

[0082] Combining Example 7 and Comparative Examples 5-8 with Table 2, it can be seen that precisely controlling the residence time of the surface treatment agent on the wood surface can effectively improve the appearance of the wood, giving it better texture clarity and three-dimensional effect. When the residence time is short, the improvement in the texture clarity of the wood is not obvious. When the residence time is long, the burrs of the wood are raised higher, but the raised burrs will become brittle and will powderize upon touch, resulting in poor texture clarity and poor three-dimensional effect.

[0083] The above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the same. Although the above embodiments provide a detailed description of the present invention, relevant technical personnel should understand that the specific implementation methods of the present invention can still be modified or replaced by equivalents. Any modifications and equivalent replacements that do not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
