Description

Technical Field

[0001] The utility model relates to a solid wood floor heating floor, in particular to an environmentally friendly, moisture-proof, glue-free pure solid wood floor heating floor. Background Art

[0002] Solid wood floor heating floors are usually covered with a backing film on the back for reasons such as moisture-proof, quiet, and beautiful. There are generally two types of backing films used on the market: PP film and PE film, which are adhered with glue (usually acrylic water-based pressure-sensitive adhesive). However, this method (hereinafter referred to as adhesive lamination) has the following problems: 1. Although the acrylic water-based pressure-sensitive adhesive used in adhesive lamination is more environmentally friendly than other glues, it still releases a certain amount of VOC, which poses a health hazard in floor heating (high temperature) environments; 2. Acrylic water-based pressure-sensitive adhesive has a slight odor. If the floor is paved over a large area, it may cause discomfort to people who are sensitive to odors; 3. With adhesive lamination, water vapor can easily enter the floor through the gaps in the glue, affecting moisture-proof performance; 4. Acrylic water-based pressure-sensitive adhesive has poor water resistance. If the floor is in a humid environment for a long time, the backing film is likely to fall off.

[0003] Therefore, the existing technology has the problems that the environmental protection performance does not meet the market consumption upgrade demand, the moisture-proof effect is poor, and the back film has poor weather resistance and is easy to fall off. Utility Model Content

[0004] The purpose of the utility model is to provide an environmentally friendly and moisture-proof glue-free pure solid wood floor heating floor. The utility model has the characteristics of being able to effectively improve environmental protection performance, enhance moisture-proof effect and enhance the adhesion firmness of the back film.

[0005] The technical solution of the utility model is: an environmentally friendly, moisture-proof glue-free pure solid wood floor heating floor, comprising a solid wood floor, a PES hot-melt film is arranged on the back of the solid wood floor; the thickness of the PES hot-melt film is 0.08-0.2mm.

[0006] In the aforementioned environmentally friendly, moisture-proof glue-free pure solid wood floor heating floor, the thickness of the PES hot-melt film is 0.1 mm.

[0007] In the aforementioned environmentally friendly and moisture-proof glue-free pure solid wood floor heating floor, the back side of the solid wood floor is a flat structure.

[0008] Compared with the prior art, the utility model applies PES hot-melt film as a backing film to solid wood floor heating floors, thereby realizing glue-free lamination. Compared with traditional PP film and PE film, it has the following advantages:

[0009] 1) Improved environmental performance. According to tests, the formaldehyde emission of PES hot-melt film laminated floor is 31% of that of PE film glue laminated floor.

[0010] 2) No glue is added during the PES hot melt film lamination process, and the PES film itself is odorless, so no odor is generated;

[0011] 3) Improved moisture resistance;

[0012] 4) The adhesion strength of the backing film is also enhanced, which can effectively prevent the backing film from falling off;

[0013] 5) Strictly limiting the thickness of the PES hot-melt film can also effectively improve the quietness performance.

[0014] In summary, the utility model has the characteristics of being able to effectively improve environmental protection performance, enhance moisture-proof effect and enhance the adhesion firmness of the back film. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0018] Embodiment. A glue-free pure solid wood floor heating floor that is both environmentally friendly and moisture-proof, comprising: Figure 1 As shown, it includes a solid wood floor 1, and a PES hot-melt film 2 is provided on the back of the solid wood floor 1; the thickness of the PES hot-melt film 2 is 0.08-0.2mm.

[0019] Preferably, the thickness of the PES hot-melt film 2 is 0.1 mm.

[0020] The back side of the solid wood floor 1 is a flat structure.

[0021] A glue-free laminating process for a pure solid wood floor heating floor that is both environmentally friendly and moisture-proof, comprising the following steps:

[0022] S1. Select a hot melt film with a release paper on the back;

[0023] S2, placing the hot melt film on the back of the floor, with the hot melt film side in contact with the floor, and the release paper side in contact with the hot press platen;

[0024] S3, controlling the temperature of the hot press plate to maintain at 125-135°C, and hot pressing the hot melt film for 20-30s, so that the hot melt film is in a semi-molten state;

[0025] Preferably, in step S3, the temperature of the hot press plate is 130°C and the hot pressing time is 25 seconds. Note: The melting point of PES hot melt film is 120°C, and the hot press temperature is set at 130°C to ensure that the hot melt film can melt. After 25 seconds of hot pressing, the hot melt film just enters a semi-molten state.

[0026] S4. Cool for 8-12 minutes (preferably 10 minutes) to allow the semi-molten hot melt film to cool and solidify and adhere to the back of the floor; and on the side in contact with the pressing plate, there is a layer of release paper to ensure that the hot melt film will not adhere to the hot pressing plate.

[0027] S5. Tear off the release paper and cut off the excess backing film to obtain the finished laminated solid wood floor heating floor.

[0028] After tearing off the release paper, use the automatic film cutting equipment to cut off the excess backing film.
