Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile accessories, in particular to an automobile interior decoration part. Background Art
[0002] Currently, bamboo-textured automotive interiors are typically produced using planing equipment to slice bamboo unit boards, resulting in a thin, uniformly thick bamboo veneer. This planed veneer exhibits a broad, uniform surface texture with distinct bamboo nodes. With the increasing diversity of automotive interiors, a single, uniform bamboo texture is no longer sufficient to meet the needs of automakers and vehicle users.
[0003] In addition, when planing the bamboo unit board, it is necessary to install the bamboo unit board on the claws of the planing equipment. The thickness of the part of the bamboo unit board clamped by the claws is about 30mm. This part of the bamboo unit board cannot be planed, resulting in loss of raw materials.
[0004] Therefore, it is necessary to design an automotive interior trim to increase the diversity of bamboo texture appearance and reduce the loss of planed raw materials. Summary of the Invention
[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and provide an automobile interior decoration part, so as to increase the diversity of bamboo texture appearance and reduce the loss of planed raw materials.
[0006] In order to achieve the above-mentioned purpose, the utility model is an automobile interior decoration part, which includes a base material layer, an adhesive layer, and a bamboo skin layer arranged in sequence. The back side of the bamboo skin layer is adhered to the surface of the base material layer by the adhesive layer. The bamboo texture surface of the bamboo skin layer is distributed with a number of dark spots. The bamboo skin layer is a slicing material of bamboo square, and the bamboo square is a stacked and glued structure composed of more than two layers of bamboo unit boards.
[0007] The bamboo unit board is a glued structure composed of a plurality of bamboo strips.
[0008] The bamboo strips are carbonized bamboo strips that are finely planed or finely planed in slices.
[0009] The moisture content of the carbonized bamboo strips is 8-12%.
[0010] The dark spots are formed by fungi and have been inactivated.
[0011] The sizes, shapes, positions and distribution densities of the several dark patches are all random.
[0012] The surface of the bamboo skin layer is provided with a decorative layer, which is a paint layer.
[0013] The adhesive layer comprises non-woven fabric.
[0014] Compared to existing technologies, this new bamboo veneer layer features randomly distributed dark patches on its surface, creating a diverse bamboo texture. Combined with a decorative layer, this can further meet the diverse needs of interior design. Bamboo squares composed of two or more layers of bamboo unit boards increase the thickness that can be sliced by slicers, thereby reducing the loss of raw materials during slicing and saving costs.

[0020] The present invention will now be further described with reference to the accompanying drawings.
[0021] See also Figures 1 to 3 The utility model is an automobile interior decoration part, comprising a base material layer 1, an adhesive layer 2, and a bamboo skin layer 3 arranged in sequence. The back of the bamboo skin layer 3 is adhered to the surface of the base material layer 1 by the adhesive layer 2. The bamboo texture surface of the bamboo skin layer 3 is distributed with a plurality of dark spots 31. The bamboo skin layer 3 is a slicing material of bamboo square 5, and the bamboo square 5 is a stacked and glued structure composed of more than two layers of bamboo unit boards 51.
[0022] Taking a three-layer bamboo unit board 51 as an example, the thickness of the stacked and glued bamboo planks 5 is 60mm. Excluding the size of the planer's jaws, the thickness that can be sliced is approximately 30mm, reducing the loss of planed raw material and saving costs. The length, width, and thickness of the bamboo planks 5 can be flexibly adjusted based on the actual usage scenario and order quantity.
[0023] The surface of the bamboo skin layer 3 is provided with a decorative layer 4, which is a paint layer. Since the bamboo skin layer 3 has been carbonized twice, all active ingredients are inactivated, and no special decorative layer is required to prevent the volatilization of fungal powder. The decorative layer adopts the same decorative layer as the ordinary real wood decorative layer, such as paint that can provide a concave and convex touch, or a metallic luster, or other decorative effects, etc., to achieve more colors and levels of decorative effects.
[0024] The adhesive layer 2 comprises a non-woven fabric, which is bonded to the bamboo skin layer 3 by hot pressing through adhesive or adhesive paper to obtain a composite non-woven fabric bamboo skin layer 3.
[0025] Carbonized bamboo strips are made by secondary carbonization after fungi form dark patches on the surface of fresh bamboo strips. The moisture content of carbonized bamboo strips is 8-12%. The specific preparation method of carbonized bamboo strips is as follows:
[0026] Fresh nanmu bamboo with a moisture content of 20-50%, a diameter of 15-30 cm, and a bamboo age of 2-6 years is cut into cylindrical bamboo segments with a length of 1-2 meters. The bamboo segments are then broken into bamboo strips with a width of approximately 2.5 cm and a thickness of 8-15 mm. The bamboo strips are then placed in a rough planer to remove the green bamboo, bamboo nodes, and bamboo yellow, completing the pre-processing.
[0027] The pretreated fresh bamboo strips were placed in a closed space with an air humidity of 40-80% and a temperature above 0°C for 1-15 days. Because fresh bamboo strips contain small amounts of active organic components such as sugars, proteins, and starch in addition to cellulose, hemicellulose, and lignin, fungi such as Penicillium and Rhizopus nigricans can grow on the fresh bamboo strips, forming dark patches. The size, shape, location, and distribution density of these patches are random and primarily depend on the distribution of active organic components within the fresh bamboo strips.
[0028] The bamboo strips with dark spots on the surface are removed and placed in a carbonization furnace and a drying furnace. After two high-temperature and high-pressure carbonizations and two dryings, the active organic components in the bamboo strips will decompose or precipitate, and the fungi and bacteria will be inactivated. Finally, carbonized bamboo strips with a moisture content of about 10% are obtained.
[0029] Bamboo strips 52 are finely planed or sliced carbonized bamboo strips. Fine planing: The carbonized bamboo strips are placed in a fine planer for fine planing, resulting in strips with a fixed width of 20 mm and a thickness of 6-12 mm. Due to the fine planing, the surface of the bamboo strips is clean and retains its natural color. Some darker spots remain irregularly on the surface, forming bamboo strips 52. Sliced fine planing: Carbonized bamboo strips with a thickness of 8-15 mm are placed in a slicer to separate them into multiple pieces, resulting in thinner bamboo slices or strips. These are then placed in a fine planer for fine planing, forming bamboo strips 52.
[0030] See also Figure 4 、 Figure 5 The bamboo unit board 51 is a glued-together structure composed of several bamboo strips 52. The dimensions of the bamboo unit board 51 are generally 1600 × 600 × 20 mm, and the specific dimensions can be adjusted according to actual needs. The bamboo unit board's length of 1600 mm is a common size used by bamboo veneer industry equipment and a relatively economical cutting length for nanmu bamboo. The width of 600 mm is a dimension that covers most applications in residential and automotive applications. The thickness of 20 mm is the width of the bamboo strips 52 after planing or slicing.
[0031] The bamboo unit panels 51 are stacked and glued to form a bamboo square 5 and placed in a slicer for sliced. The sliced material of the bamboo square 5 is the bamboo veneer layer 3, and a plurality of dark spots 31 are randomly distributed on the bamboo texture surface.
[0032] The bamboo skin layer of this utility model features randomly distributed dark patches on its surface, creating a diverse bamboo texture. Combined with the decorative layer, it can further meet the diverse needs of interior design. Bamboo blocks composed of two or more layers of bamboo unit boards increase the thickness that can be sliced by the slicer, thereby reducing the loss of raw materials during slicing and saving costs.
