Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to a bamboo-wood composite floor. Background Art

[0002] Car floors are generally installed at the bottom of the passenger compartment of a car, playing the role of heat insulation, sound insulation and load bearing. In an era of increasing pursuit of high performance, environmental protection, energy saving, lightweight and comfort, the ride comfort of a car, like its appearance, has become an important factor in people's car purchase. Therefore, the requirements for car interior parts are also getting higher and higher.

[0003] Due to the long service life of automobiles, high quality requirements are placed on automobile floors. In the prior art, wooden floors are generally used. However, the long growth cycle of the raw materials for wooden floors and the impact of excessive logging on the environment have limited the development of wooden floors in the field of automobile interiors. There are also some composite boards on the market that use the scraps generated during the processing of wood and add chemical adhesives to make them for use as automobile floor panels. These composite boards have poor mechanical properties and will deform after long-term use. Utility Model Content

[0004] The utility model aims at the deficiencies of the prior art and provides a bamboo-wood composite floor with high mechanical properties and long service life.

[0005] In order to achieve the above technical objectives, the utility model proposes the following technical solutions: a bamboo-wood composite floor, comprising a bamboo veneer layer, wherein the upper and lower end surfaces of the bamboo veneer layer are provided with a plurality of veneer layers, the end surface of the veneer layer away from the bamboo veneer layer is provided with a waterproof layer, the bamboo veneer layer and the veneer layer, and the veneer layer and the waterproof layer are fixed by a phenolic resin adhesive, the veneer layer comprises a plurality of natural veneers laid on the same horizontal plane, and two adjacent pieces of natural veneers are fixed by a miter joint or an overlap joint.

[0006] Furthermore, the bamboo veneer layer includes a plurality of bamboo veneers laid on the same horizontal plane, and two adjacent bamboo veneers are fixed by horse nails.

[0007] Furthermore, 1-2 layers of glass fiber cloth are arranged between any two layers of the wood veneer layers.

[0008] Furthermore, the thickness of the bamboo veneer layer is 6-8 mm.

[0009] Furthermore, the waterproof layer is a coated paper or a fiberglass sheet, and the bamboo-wood composite floor is covered with a concave-convex pattern.

[0010] Compared with the prior art, the utility model has the following beneficial effects: the utility model has a novel structure, ingenious conception, and simple and convenient operation, and has the following advantages compared with the prior art: the utility model uses bamboo veneer as the board core of the bamboo-wood composite floor, which not only increases the heat insulation performance, but also can significantly increase the mechanical properties and anti-deformation performance of the bamboo-wood composite floor under the bonding action of the wood veneer layer and the phenolic resin glue, and at the same time, the strength of the bamboo-wood composite floor can be further improved by the glass fiber cloth; the bamboo veneer layer is composed of a plurality of bamboo veneers spliced ​​by horse nails, which can reduce the generation of voids; by pressing a concave and convex pattern on the end surface of the bamboo-wood composite floor, not only the overall aesthetics is increased, but also it has anti-slip performance, which increases the friction between the soles of people's feet and the car floor, so that the center of gravity of standing passengers is more stable.

[0014] The following are specific embodiments of the present invention, and the technical solution of the present invention is further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0015] like Figure 1 and 2 As shown, the utility model provides a bamboo-wood composite floor, comprising a bamboo veneer layer 1, the upper and lower end surfaces of the bamboo veneer layer 1 are each provided with three veneer layers 2, the end surface of the veneer layer 2 away from the bamboo veneer layer 1 is provided with a waterproof layer 3, the bamboo veneer layer 1 and the veneer layer 2, as well as the veneer layer 2 and the waterproof layer 3 are all fixed by phenolic resin adhesive, the bamboo veneer layer 1 comprises a plurality of bamboo veneers 11 laid at the same level, two adjacent bamboo veneers 11 are fixed by horse nails 12, the veneer layers 2 each comprise a plurality of natural veneers laid at the same level, two adjacent natural veneers are fixed by mitering or overlapping.

[0016] like Figure 1 and 2As shown, since bamboo has the advantages of low thermal conductivity, high hardness, long service life and fast growth rate, the bamboo veneer layer is made of bamboo as the core of the car floor in the utility model, which is not only durable, but also can well reduce the thermal conductivity of the car floor and improve the strength of the car floor; the bamboo veneer layer 1 includes a plurality of bamboo veneers 11, and two adjacent bamboo veneers 11 are fixed by horse nails 12, which can prevent the bamboo veneers 11 from separating from each other and generating voids, and a plurality of veneer layers 2 are bonded to the upper and lower end surfaces of the bamboo veneer layer 1 by phenolic resin glue, and the plurality of veneer layers 2 are bonded together by phenolic resin glue, and the veneer layer 2 is selected from natural veneer, and moisture is removed during the processing, so it is not easy to deform and has a long service life, and a waterproof layer 3 is bonded to the other end surface of the veneer layer 2 away from the bamboo veneer layer 1 by phenolic resin glue, which can prevent moisture from penetrating and increase the service life of the bamboo-wood composite floor.

[0017] One to two layers of glass fiber cloth 4 are arranged between any two layers of the wood veneer layers 2 .

[0018] like Figure 1 As shown, the fiberglass cloth 4 can be provided to improve the impact resistance of the bamboo-wood composite floor. Once an impact occurs, cracking can be effectively avoided, thereby further improving the mechanical properties of the bamboo-wood composite floor.

[0019] The bamboo veneer layer 1 is made of a bamboo veneer with a thickness of 6-8 mm, the waterproof layer 3 is made of coated paper or fiberglass sheet, and the bamboo-wood composite floor is covered with a concave-convex pattern.

[0020] like Figure 1 As shown, both the coating layer and the fiberglass sheet are waterproof and corrosion-resistant. After processing, a concave-convex pattern is pressed on the top of the bamboo-wood composite floor, that is, the coating paper, which not only improves the aesthetics of the bamboo-wood composite floor, but also improves its anti-slip ability, increases the friction between people's feet and the car floor, and makes the center of gravity of standing passengers more stable.

[0021] Working principle: Material selection: The bamboo veneer 11 is made of bamboo strips with a thickness of 6-8mm and a width of 20-30mm; 3 layers of veneer layers 2 are selected, and the veneer layers 2 are all made of natural veneer, and the waterproof layer 3 is made of coated paper;

[0022] Preparation process: the coated paper is soaked in phenolic resin glue for a certain period of time and taken out to dry, so that the coated paper is soaked in phenolic resin glue, and the bamboo veneer 11, natural veneer and glass fiber cloth 4 are all coated with phenolic resin glue and dried;

[0023] Processing process: The coated paper is laid on a flat surface, and two layers of veneer layers 2, a layer of glass fiber cloth 4, a layer of veneer layer 2, a layer of bamboo veneer layer 1, a layer of veneer layer 2, a layer of glass fiber cloth 4, two layers of veneer layers 2 and a layer of coated paper are laid on the end surface of the coated paper from bottom to top. After laying, it is hot-pressed by a hot press to melt the dried phenolic resin glue and make them bonded together. Finally, an embossing machine is used to emboss a concave and convex pattern on one end surface of the bamboo-wood composite floor.
