Description

Technical Field

[0001] The present application relates to the field of coating technology, and in particular to a wood grain protective paint for furniture panels, a preparation method thereof, and an application thereof. Background Art

[0002] In the process of furniture board production, a common method to protect the board is to paint its surface. Some furniture surfaces need to show their wood grain texture, so they will be painted with transparent or translucent protective paint. On some high-end furniture, after using protective paint, a bright, transparent / translucent paint layer will be formed on the surface of the furniture board. Because this paint layer is bright and transparent, it is particularly afraid of wear and scratches. Even the slightest marks on the surface can be clearly seen. Therefore, in addition to the basic requirements for the brightness and transparency of this type of protective paint, its wear resistance and scratch resistance are required to be higher. Summary of the invention

[0003] In order to solve at least one of the above technical problems, a wear-resistant and scratch-resistant protective paint is developed. The present application provides a furniture board wood grain protective paint, a preparation method and an application thereof.

[0004] On the one hand, the present application provides a furniture board wood grain protective paint, which is prepared by including the following components in parts by weight:

[0005] Polyurethane 100 parts;

[0009] 0.2-0.4 parts of silicone defoamer;

[0010] 1.5-1.8 parts of nano silicon dioxide;

[0011] 6 to 6.5 parts of deionized water.

[0012] Optionally, the particle size of the first wax powder is 1-10 μm; the particle size of the second wax powder is 0.01-0.2 μm.

[0013] Optionally, the weight ratio of the total weight of the first wax powder and the second wax powder to the polyurethane is 5.5 to 7:100.

[0014] Optionally, the weight ratio of the first wax powder to the second wax powder is 5.3-6.9:1.

[0015] Optionally, the first wax powder wax component is selected from one or a combination of polyethylene wax, polypropylene wax and polytetrafluoroethylene wax;

[0016] And / or, the component of the second wax powder is selected from one or a combination of polyethylene wax, polypropylene wax and polytetrafluoroethylene wax.

[0017] In a second aspect, the present application provides a method for preparing the above-mentioned furniture board wood grain protective paint, comprising the following steps:

[0018] S1. Pour deionized water into a container according to the formula amount, and then add polyurethane and the first wax powder and stir;

[0019] S2. During the stirring process, add polydimethylsiloxane, silicone defoamer, and nano-silicon dioxide, and continue stirring;

[0020] S3, adding the second wax powder and stirring, mixing evenly to obtain the furniture board wood grain protective paint.

[0021] Optionally, in S1, the stirring speed is 400 r / min and the stirring time is 20 min.

[0022] Optionally, in S2, the stirring speed is 400 r / min and the stirring time is 10 min.
