Description

Technical Field

[0001] The present invention relates to the technical field of floor laminating, and particularly to a special protective film for solid wood floors with high thermal conductivity and wear resistance. Background Art

[0002] As a preferred material for high-end home decoration, solid wood floors are favored by consumers for their natural beauty, comfortable texture, and strong durability. However, solid wood floors also face some challenges during use, especially in terms of thermal conductivity and wear resistance.

[0003] In terms of thermal conductivity, the thermal conductivity coefficient of solid wood floors is relatively low, resulting in a slow heating rate and uneven temperature distribution of the floors during the heating season. This not only affects the indoor comfort but also causes energy waste. To improve the thermal conductivity of solid wood floors, some geothermal floors using materials such as metals or graphite have emerged in the market. However, these materials often change the natural texture and beauty of solid wood floors and have a high cost.

[0004] In terms of wear resistance, although solid wood floors are durable, they are still prone to problems such as wear and scratches during long-term use, especially in areas with high foot traffic. This not only affects the beauty of the floors but also shortens their service life. To enhance the wear resistance of solid wood floors, the traditional approach is to apply coating treatments to the floor surface, such as using wear-resistant coatings like polyurethane and acrylic. However, these coating materials often have problems such as easy aging and peeling, and it is difficult to meet the requirements of high thermal conductivity and wear resistance simultaneously.

[0005] Therefore, there is an urgent need to provide a special protective film for solid wood floors with high thermal conductivity and wear resistance to solve the above problems. Summary of the Invention

[0006] To overcome the deficiencies of the prior art, the present invention provides a special protective film for solid wood floors with high thermal conductivity and wear resistance, which can transfer heat more effectively, enabling the solid wood floor to reach the required temperature faster and more evenly during heating, thereby improving the stability of the indoor temperature, having excellent wear resistance, and extending the service life of the solid wood floor.

[0007] The technical solution is as follows:

[0008] A special protective film for solid wood floors with high thermal conductivity and wear resistance, the raw materials of which include: a base material selected from one or more of polyimide, polytetrafluoroethylene, and polyester;

[0009] a wear resistance enhancing component selected from one or more of ceramic particles and metal powders;

[0010] The mass ratio of the base material to the wear resistance enhancing component is 1:2;

[0011] Heat-resistant additives, selected from one or more of graphite and inorganic fillers;

[0012] The adhesion layer is coated with an adhesive on the surface. The adhesive selects polyurethane, acrylic or epoxy resin as the base material, and a toughening agent, fillers and additives are added. The mass ratio of the base material, toughening agent, fillers and additives is 60:20:15:5.

[0013] Preferably, the adhesive selects polyurethane (PU), acrylic (ACRYLIC) or epoxy resin (EPOXY) as the base material, an appropriate amount of toughening agent is added, fillers (talc powder, silica) are added to enhance the mechanical strength and wear resistance of the adhesive, and an appropriate amount of additives such as antioxidants and tackifiers are added to improve the performance of the adhesive. The ratio of the base material: toughening agent: fillers: additives is 60:20:15:5 (weight ratio), and the specific ratio can be adjusted according to actual needs.

[0014] Preferably, the preparation method of the adhesive is as follows:

[0015] Step 1: Mix the polyurethane and the toughening agent in proportion and stir evenly.

[0016] Step 2: Gradually add inorganic fillers and continue to stir to ensure uniform dispersion of the fillers.

[0017] Step 3: Add additives and stir evenly to form a uniform mixture of the adhesive.

[0018] Step 4: Debubble the mixture to remove air bubbles. The debubbling treatment is carried out by vacuum debubbling or ultrasonic debubbling to obtain the final adhesive.

[0019] Preferably, the adhesion layer has a certain reversibility, which is convenient to remove during installation and replacement without leaving residual glue, avoiding damage to the floor surface.

[0020] Preferably, the preparation method of the special protection film for solid wood floors with high thermal conductivity and wear resistance is as follows:

[0021] S1. Select a base material, mix it with a wear-resistant strengthening component according to the weight ratio, and dissolve it in a solvent to form a uniform solution, and adjust the particle size and distribution of ceramic particles as needed to enhance the wear resistance of the film.

[0022] S2. Add heat-resistant additives such as graphite and an adhesive, and further stir evenly to ensure uniform distribution of all components. Use methods such as mechanical stirring and ultrasonic dispersion to ensure the uniformity of the materials.

[0023] S3. Uniformly coat the mixed solution on the surface of the substrate, and use the hot pressing or hot stretching process to enhance the structural strength of the film. The temperature during the hot pressing process is 100 - 200 °C to ensure the uniformity and adhesion of the film material.

[0024] S4. Conduct high-temperature curing treatment on the film material to ensure that the film material maintains stable performance at high temperatures, and at the same time improve its high-temperature resistance and wear resistance.

[0025] Compared with the prior art, the above technical solution conceived by the present invention has the following advantages:

[0026] 1. The selection of the base material and heat-resistant additive of this invention patent enables the film to maintain stable performance in high-temperature environments and will not be damaged due to thermal stress. The protective film has high thermal conductivity, can effectively transfer heat, and improve the heating efficiency of the floor heating system.

The protective film has excellent wear resistance, can effectively resist friction and impact in daily use, reduce the wear of solid wood floors, and extend the service life of the floors.

[0028] 3. The protective film of the present invention has high transparency. After installation, it does not change the original appearance of the floor and does not affect the natural beauty of the floor.

[0029] 4. The adhesion layer of the protective film of the present invention has weak adhesion, is convenient for installation and disassembly, leaves no glue marks, and the film layer is easy to clean and maintain simply.

[0030] 5. The present invention is applicable to various types of solid wood floors and can effectively play a role in the floor heating system, solving the problem that traditional floor films cannot balance thermal conductivity and wear resistance. Specific embodiments

[0073] Step Five: Film coating and hot pressing:

[0074] Evenly coat the prepared solution on the surface of the substrate and perform hot pressing treatment, using

[0075] a temperature of 100°C - 200°C and 18 MPa.
