Description

Technical Field

[0001] This invention relates to the field of panel surface preparation technology, specifically a preparation process for leather and fabric panel surface. Background Technology

[0002] Currently, in furniture manufacturing, interior decoration, and other fields, decorative layers are often applied to the surface of wood panels for aesthetic or fire-resistant purposes. Existing decorative bonding processes typically involve applying the decorative layer to the panel surface, followed by cutting, edge banding, and other finishing steps.

[0003] However, when common panel finishes are bonded to panels, issues such as fraying, chipping, and fiber residue often occur at the edges, affecting aesthetics and significantly reducing the usability of the panel finishes. To address these issues, we propose a preparation process for leather and fabric panel finishes. Summary of the Invention

[0004] The purpose of this invention is to provide a preparation process for leather and fabric panel finishes to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a preparation process for a leather and fabric panel finish, comprising the following steps: I. Preparing the leather surface layer, including the following steps: S1. Place 50 parts of polyurethane resin, 3 parts of heat stabilizer, 20 parts of high-temperature resistant polytetrafluoroethylene and 5-10 parts of nylon-66 salt into a mixer in sequence, then add appropriate amounts of solvent, filler and curing agent and mix and stir to obtain mixture solution A. S2. Apply mixture solution A evenly onto the release paper roll; S3. The raw materials in S2 are dried in an oven. After the solvent in the mixture solution A has completely evaporated, a high-density film surface layer is obtained. Then, the release paper roll is taken out and the high-density film surface layer is separated from the release paper roll to obtain a high-density and high-temperature resistant surface layer B. II. Preparation of the base layer, including the following steps: S4. The raw materials selected according to the following weight ratio are: 5 parts heat stabilizer, 80 parts water-based PU resin, 2-5 parts plasticizer, 1-20 parts water, and 1-8 parts fiber powder. S5. The above raw materials are mixed together using a mixer and stirred at room temperature and pressure to complete the slurry preparation; S6. Feed the above-mentioned slurry into the foaming machine, adjust the feed rate of the slurry and the air intake rate of the foaming machine, and obtain the slurry A with the required bubble size according to the volume ratio of 1:2. S7. Apply the above slurry A evenly to the release paper roll, and then put it into the oven for drying. S8. The temperature of the oven is controlled at 100-130℃, and the speed is determined according to the thickness of the product. Finally, the product is cooled after being taken out of the oven to form a base layer. The base layer is then separated from the release paper roll to obtain the final base layer A. III. The process of laminating the base layer with the top layer includes the following steps: S9. The surface layer B obtained in S3 and the base layer A obtained in S8 are combined using a composite equipment to form a tear-resistant leather layer without a backing fabric, which meets the standard for being able to be pressed.

[0006] Furthermore, the coating amount of the mixture solution A in S2 on the release paper is 100-150 g / m².

[0007] Furthermore, in S7, the coating amount of slurry A on the release paper is 150-250 g / m².

[0008] Furthermore, the stirring time in S5 is 15-35 minutes.

[0009] Furthermore, the mixing and stirring time in S1 is 25-40 minutes.

[0010] Furthermore, the drying time in S3 is 3-8 minutes.

[0011] Furthermore, the solvent in S1 is an organic solvent, which is selected from one or a mixture of two of butyl acetate and ethyl acetate.

[0012] Furthermore, the speed in S8 is controlled at 3-12 meters per minute.

[0013] Furthermore, the filler in S1 is nano-silicon oxide and antimony-tin oxide.

[0014] Furthermore, the stirring time in S5 is 20-30 minutes.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The leather produced by this invention breaks through the limitation of being limited to melamine paper film for surface decoration, and allows for the use of more diversified surface decoration materials, which can achieve a variety of different materials in terms of feel, texture and texture, such as leather flooring, wall panels, doors, wardrobes, stairs, decorative panels and so on.

[0016] 2. The backing-less leather layer of this invention is bonded to the surface of boards, metal, or other materials using appropriate adhesives, roller bonding, cold application, or hot pressing processes to form finished decorative panels, furniture panels, etc. This achieves strong bonding, prevents peeling and edge cracking during panel cutting and milling, and eliminates backing fiber leakage, achieving the same effect as conventional melamine paper film decorative panels. It can be directly used in paint-free panel cabinet production lines, overcoming the limitations of manual production for leather products, resulting in more perfect products, lower costs, higher efficiency, and more diversified decorative designs and applications.

[0017] 3. This type of process is not limited to leather products; it can also be extended to other soft materials to remove the fiber base and composite them. Detailed Implementation
