[0002] At present, there are two main types of plywood for passenger cars: one is full wood plywood and the other is bamboo-wood composite plywood. Full wood plywood mainly relies on imports and has limited timeliness. Bamboo has the advantages of good quality, fast growth, short cycle, high yield, good performance, and is biodegradable. It is a natural fiber material. However, the bamboo-wood composite plywood currently used in passenger cars is generally a multi-layer structure made of multiple layers of bamboo pieces. The compression rate during the processing and pressing process is relatively large, making the structure dense and heavy, which not only affects the transportation energy consumption, but also has high material input and production costs.

[0029] Figure 1 This is a schematic diagram of the structure of the bamboo-wood composite floor 1 of the utility model. Figure 2 This is a schematic diagram of the structure of the core board 11 provided by the utility model. For ease of understanding and description, the state of the bamboo-wood composite floor 1 placed on the ground is used as a reference, the up and down direction of the bamboo-wood composite floor 1 is used as the vertical direction below, and the direction perpendicular to the vertical direction is used as the horizontal direction below, wherein the horizontal direction below includes the lateral and transverse directions perpendicular to each other.

[0030] See also Figure 1 and Figure 2 The present application provides a bamboo-wood composite floor 1, which includes a core board 11, a first layer board 12 and a second layer board 13, wherein the first layer board 12 and the second layer board 13 are arranged on the upper and lower sides of the core board 11, and the core board 11 is bonded to the first layer board 12 and the second layer board 13 respectively. Figure 2 and Figure 3 , Figure 3 The structure diagram of two adjacent bamboo strips 111 provided by the utility model, the core board 11 includes a bonding part 112 and a plurality of bamboo strips 111, the length direction of each bamboo strip 111 extends along the bamboo fiber direction, and each bamboo strip 111 extends transversely, and the plurality of bamboo strips 111 are connected along the bamboo fiber direction perpendicular to the bamboo strip 111, and the bonding part 112 is arranged between any two adjacent bamboo strips 111. The upper and lower surfaces of the bamboo strip 111 are respectively a bamboo green surface 1111 and a bamboo spring surface 1112.

[0031] Specifically, the bamboo strips 111 are cut into blocks from bamboo tubes and processed, wherein the cross section of the bamboo strips 111 is rectangular, and the original bamboo green surface 1111 and bamboo spring surface 1112 are retained on the upper and lower surfaces of the processed bamboo strips 111. The plurality of bamboo strips 111 can be sequentially assembled along the bamboo fiber direction perpendicular to the bamboo strips 111 through the bonding portion 112 located on the side to form the core board 11. The first layer board 12, the core board 11 and the second layer board 13 are sequentially stacked up and down to form a three-layer composite structure. The utility model adopts the bamboo strips 111 with the bamboo green surface 1111 and the bamboo spring surface 1112. On the one hand, it ensures that the bamboo strips 111 themselves have sufficient thickness, improves the yield of the bamboo strips 111, and reduces the production cost. On the other hand, the processed bamboo strips 111 retain the bamboo green surface 1111 and the bamboo spring surface 1112, so that the bamboo strips 111 have extremely high tissue density and hardness, thereby improving the structural strength of the bamboo strips 111 and improving the service life. On the other hand, the bamboo strips 111 have an original thickness, which enables multiple bamboo strips 111 to be directly laterally spliced ​​along a direction perpendicular to the fiber direction of the bamboo strips 111, and laid flat to form a single-layer core board 11, without the need for vertical pressing of multiple layers of bamboo pieces. The bamboo strips 111 themselves have a low compression rate, which reduces the compression rate of the core board 11 and reduces the weight of the core board 11. In addition, the three-layer composite structure in which the first layer 12 and the second layer 13 are bonded to the upper and lower sides of the core board 11 ensures the structural stability of the bamboo-wood composite floor 1.

[0032] The length direction of the bamboo strips 111 is arranged in the same direction as the bamboo fiber direction, and multiple bamboo strips 111 are laterally spliced ​​in a direction perpendicular to the bamboo fiber direction, which can improve the overall strength and stability of the floor structure. The first layer 12, the second layer 13 and the core board 11 are all flattened and extended in the horizontal direction, and the length extension direction of the bamboo strips 111 is perpendicular to the splicing direction of the multiple bamboo strips 111. Figure 1 As shown, the bamboo strips 111 extend along the left-right direction, and a plurality of bamboo strips 111 are sequentially connected and bonded along the front-back direction. The left-right direction shown in the figure is the transverse direction, and the front-back direction is the lateral direction.

[0033] In this embodiment, the bamboo strips 111 are carbonized bamboo strips 111 that have been subjected to high-temperature carbonization treatment, have good anti-corrosion and anti-insect properties, and improve the stability of the bamboo-wood composite floor 1. Moreover, the bamboo strips 111 are fine-planed bamboo strips 111. Specifically, the bamboo strips 111 are formed into a long strip structure with certain specifications and dimensions and a substantially rectangular cross section after being machined by rough planing and fine planing after the bamboo tube is split, and a certain bamboo green surface 1111 and bamboo spring surface 1112 are retained, which is convenient for the subsequent splicing of multiple bamboo strips 111 and the bonding with the first layer 12 and the second layer 13.

[0034] In this embodiment, the thickness of the bamboo strip 111 is 4 mm to 10 mm; the width direction of the bamboo strip 111 extends perpendicular to the bamboo fiber direction of the bamboo strip 111, and the width of the bamboo strip 111 is 10 mm to 30 mm. Specifically, the thickness direction of the bamboo strip 111 extends in the up-down direction, and the processing thickness of the bamboo strip 111 is limited to 4 mm to 10 mm, and the width of the bamboo strip 111 in the front-back direction is limited to 10 mm to 30 mm, which can facilitate factory production. In actual production, the processing thickness and processing width of the bamboo strip 111 can also be adjusted according to the machine equipment and the required size of the bamboo-wood composite floor 1. Specifically, the width of the bamboo strip 111 can be adjusted to be greater than 30 mm, or less than 10 mm.

[0035] Combination Figure 2 and Figure 3 , two adjacent bamboo strips 111 are arranged in sequence along the front-to-back direction, the bamboo spring surface 1112 is arranged on the upper surface or the lower surface of the bamboo strip 111, and the bamboo green surface 1111 is correspondingly arranged on the lower surface or the upper surface of the bamboo strip 111, and the bamboo spring surface 1112 and the bamboo green surface 1111 are both extended horizontally and extend in the direction of the bamboo fibers of the bamboo strip 111. The bamboo green surface 1111 on a bamboo strip 111 can be bonded to one of the first layer 12 and the second layer 13, and the bamboo spring surface 1112 on the same bamboo strip 111 is bonded to the other of the first layer 12 and the second layer 13.

[0036] like Figure 3 As shown, in this embodiment, the directions of the bamboo green surface 1111 and the bamboo spring surface 1112 on any two adjacent bamboo strips 111 are alternately arranged. Specifically, between two adjacent bamboo strips 111, if the bamboo green surface 1111 of the first bamboo strip 111 faces downward and the bamboo spring surface 1112 faces upward, then the bamboo green surface 1111 of the second bamboo strip 111 faces upward and the bamboo spring surface 1112 faces downward, so that the bamboo strips 111 are alternately arranged in opposite directions, so that the core board 11 structure composed of multiple bamboo strips 111 is more straight and stable.

[0037] In one embodiment, at least one adjacent bamboo strip 111 may be a bamboo board group, and the bamboo green surface 1111 and the bamboo spring surface 1112 on the bamboo strips 111 of the same bamboo board group are oriented in the same direction, and the bamboo green surface 1111 and the bamboo spring surface 1112 of the bamboo strips 111 between adjacent bamboo board groups are oriented in opposite directions. There may be two or more bamboo strips 111 in a bamboo board group. Correspondingly, the specific number of bamboo strips 111 in each bamboo board group can be adjusted according to actual needs such as the width of the bamboo strips 111 and the required width of the core board 11, and this is only an exemplary description.

[0038] In addition, in fact, the directions of the bamboo green surface 1111 and the bamboo reed surface 1112 on different bamboo strips 111 can also be randomly set, or the bamboo green surface 1111 can be uniformly oriented upward or downward, and the bamboo reed surface 1112 can be uniformly oriented downward or upward. This embodiment does not impose specific restrictions on the position settings of the bamboo green surface 1111 and the bamboo reed surface 1112 of the bamboo strips 111.

[0039] like Figure 3 As shown, the adhesive part 112 is arranged on at least one side of the bamboo strip 111 between the bamboo green surface 1111 and the bamboo spring surface 1112, and the adhesive part 112 is also extended or arranged at intervals along the bamboo fiber direction of the bamboo strip 111, so as to ensure that two adjacent bamboo strips 111 can be connected and spliced. In fact, the adhesive part 112 is arranged on the opposite side between the bamboo strips 111 and the bamboo strips 111. Specifically, one of the two adjacent bamboo strips 111 may be provided with the adhesive part 112 on the opposite side, or both of the two adjacent bamboo strips 111 may be provided with the adhesive part 112 on the opposite side. The adhesive part 112 may be arranged on the front side or the rear side of the bamboo strip 111 alone, or both of the front side and the rear side of the bamboo strip 111 may be provided with the adhesive part 112.

[0040] In this embodiment, the bonding part 112 includes phenolic resin glue, and the bamboo strips 111 are subjected to heat pressing and lateral pressure on the upper and lower surfaces, so that the phenolic resin glue on the bonding part 112 is cured to bond two adjacent bamboo strips 111. Specifically, the sides of the adjacent bamboo strips 111 facing each other are coated with phenolic resin glue, and a plurality of bamboo strips 111 are arranged in sequence in the front-to-back direction, and are placed in a hot press side by side to achieve lateral heating and pressure, so that the phenolic resin glue is cured and the bonding and splicing between the two adjacent bamboo strips 111 is achieved. After the plurality of bamboo strips 111 are subjected to heat pressing, the two adjacent bamboo strips 111 are almost fitted together without gaps. In addition, the bonding part 112 can also be other adhesives that can bond the bamboo strips 111. In fact, the phenolic resin glue can also be replaced by urea-formaldehyde resin, ketone-formaldehyde resin and glyoxal resin.

[0041] In addition, the first layer board 12 and the core board 11, and the second layer board 13 and the core board 11 can be bonded and spliced ​​by means of glue, and specifically, phenolic resin glue can be used to achieve bonding between any two.

[0042] In this embodiment, the floor structure of the bamboo-wood composite floor 1 is constructed between the first layer 12, the core board 11 and the second layer 13, and the thickness of the core board 11 accounts for 50% to 75% of the thickness of the floor structure. The thickness of the core board 11 accounts for half or more of the floor structure, ensuring the overall strength and hardness of the floor structure and improving the stability of the floor structure. In fact, the thickness of the first layer 12 and the second layer 13 and the board material can be consistent or different, as long as the thickness of the core board 11 accounts for 50% to 75% of the thickness of the floor structure. On the one hand, it can ensure that the strength of the floor structure meets the requirements of relevant standards, and on the other hand, it can effectively reduce the weight of the floor. At the same time, a large amount of bamboo raw materials are used, which is light carbon and environmentally friendly. In addition, the thickness ratio of the core board 11 in the floor structure can also be adjusted according to customer needs.

[0043] Furthermore, in order to improve the overall strength and stability of the floor structure, the fiber directions of the first layer 12 and the second layer 13 are staggered with the fiber directions of the bamboo strips 111. In a specific embodiment, the fiber directions of the first layer 12 and the second layer 13 are perpendicular to the fiber directions of the bamboo strips 111, and the fiber directions of the corresponding bamboo strips 111 extend in the left-right direction, while the fiber directions of the first layer 12 and the second layer 13 extend in the front-back direction, so that the fiber directions of the three layers of the first layer 12, the core board 11, and the second layer 13 are crisscrossed to improve the strength of the floor structure. The fiber directions of the first layer 12 and the second layer 13 are generally wooden boards with straight fiber directions along the front and back, and may also be fiber directions with relatively horizontal inclined lines. Overall, the fiber directions of the first layer 12 and the second layer 13 are staggered with the fiber directions of the bamboo strips 111.

[0044] Reference Figure 4 , Figure 4 for Figure 1 A partial enlarged view of the middle A area shows that the first layer 12 includes at least two first wood board units 121 stacked in sequence; the second layer 13 includes at least two second wood board units 131 stacked in sequence. Specifically, the first layer 12 is formed by at least two or more first wood board units 121 stacked in sequence along the up-down direction, and the second layer 13 is formed by at least two or more second wood board units 131 stacked in the up-down direction, which improves the structural stability of the first layer 12 and the second layer 13, improves the structural strength, and reduces deformation.

[0045] The first wood board unit 121 and the second wood board unit 131 can be one of birch veneer, poplar veneer and rubber wood veneer, etc., wherein two or more first wood board units 121 can also use the same veneer material, or different veneer materials, that is, arbitrarily select one of birch veneer, poplar veneer and rubber wood veneer, etc., and two or more second wood board units 131 can also use the same veneer material, or different veneer materials, different veneer materials, that is, arbitrarily select one of birch veneer, poplar veneer and rubber wood veneer, etc. In fact, the adjacent first wood board units 121 and the adjacent second wood board units 131 can be bonded and spliced ​​by means of cloth glue, and specifically can be bonded by phenolic resin glue.

[0046] Furthermore, the thickness of the first wood board unit 121 is 1.2 mm to 2.2 mm, and the thickness of the second wood board unit 131 is 1.2 mm to 2.2 mm, which facilitates production and ensures structural performance.

[0047] The bamboo-wood composite floor 1 in this embodiment is a new type of lightweight bamboo-wood composite floor 1 for passenger car compartments, and the specific process flow is as follows: after the bamboo strips 111 are carbonized, dried and finely planed in turn, glue is applied to the front and rear sides of the bamboo strips 111, and multiple bamboo strips 111 are placed in a hot press for side splicing and hot pressing to form a whole single-layer core board 11; the logs are peeled and dried to form a first wooden board unit 121 and a second wooden board unit 131, at least two first wooden board units 121 are stacked up and down to form a first layer board 12, and at least two second wooden board units 131 are stacked up and down to form a second layer board 13; glue is laid between the first layer board 12, the core board 11 and the second layer board 13, and then hot pressing is performed to form a floor structure; the floor structure is trimmed, packaged and stored to form the bamboo-wood composite floor 1.

[0048] The bamboo-wood composite plywood floor currently used in the existing passenger car compartment is generally formed by pressing multiple layers of bamboo pieces, and the density generally reaches 0.95g / cm3 to 1.1g / cm3. According to the above-mentioned process flow, the first layer 12, the core board 11 and the second layer 13 are sequentially spliced, so that the compression rate of the processing and pressing process is reduced, and then the density of the bamboo-wood composite floor 1 is less than 0.85g / cm3, which reduces the density of the floor structure, reduces the weight of the floor structure, reduces the production cost, and ensures the structural strength of the bamboo-wood composite floor 1. The present application provides a bamboo-wood composite floor 1 with low density, light weight, good strength, no secondary processing defects, and long service life. In addition, it can use a large amount of bamboo raw materials, is light carbon and environmentally friendly, and meets the requirements of the era of double carbon.
