Artificial floor

Abstract

The invention provides an artificial floor which comprises a floor body, and a liner part is arranged on the surface of the floor body. When the plate body is laid on a bottom floor, the liner part is in contact with the bottom floor. The board body can be a linen-like floor, a wood-like floor or a stone-like floor and other various simulation floors. The various simulation floors are poor in wear resistance, and vibration or shaking of the simulation floors in the transportation process may cause friction between the floors, so that the surfaces of the floors are easily damaged. Furthermore, the bottom floor may have an uneven surface, so that the flatness of the surface of the floor body laid on the bottom floor can be influenced. Therefore, the liner parts of the plate bodies can be used for buffering in the conveying process so as to protect collision and friction between the plate bodies. The pad portion may also act as a local deformation to intimate the surface of the underlying floor.

Description

Technical Field

[0001] The present invention relates to an artificial floor, in particular to an artificial floor with a padding portion. Background Art

[0002] Most of the existing floors use plastic floors (PVC floors). The advantages of this type of plastic floor are that it is cheap, easy to install and easy to maintain. Plastic floors have a variety of styles, such as imitation wood floors, imitation stone floors or imitation linen floors. In order to achieve the touch and anti-slip effects of the above-mentioned imitation wood floors, imitation stone floors or imitation linen floors, usually the surface of the upper floor is engraved with patterns or different materials from the lower floor (such as stone powder or wood powder, etc.) are added to the upper floor, and then further compounded with the lower floor. However, the material of the above-mentioned plastic floor has poor wear resistance. During the transportation of the floor, the transportation vehicle will inevitably vibrate up and down or shake left and right, which can easily cause the surfaces of the floors to wear each other. The thickness of the plastic floor is thin, and the plastic floor is laid on an uneven ground, and the surface of the floor is prone to appear uneven.

[0003] Furthermore, the upper floor is further provided with a connector on its circumference. The connector is a structure for connecting the upper floor and is used to connect other upper floors. The thickness of the connector is thinner than the thickness of the upper floor itself, so it is more fragile than other parts. When the upper floor with the connector is laid on an uneven ground (i.e., the lower floor), the connector is easily broken and damaged. Summary of the invention

[0004] The technical problem to be solved by the embodiments of the present invention cannot be solved by the prior art. In the prior art, due to the poor wear resistance of the floor material, the vibration or shaking during the transportation process will easily cause mutual wear between the floor surfaces. In addition, the thickness of the floor is thin, and when the floor is laid on an uneven ground, the ground is likely to appear uneven.

[0020] In the embodiment of the present invention, the cushioning part of the artificial floor can be used as a buffer during the transportation process to protect the collision and friction between the boards, and the cushioning parts of the artificial floor with different thicknesses and hardness can be used for the surface of the artificial floor with different hardness and softness materials. In addition, the board body is an independent body and can produce independent local deformation according to the unevenness of the underlying floor, so that the cushioning part of the board body can be deformed separately to adapt to the ground changes of the underlying floor, so that the board body can fit closely to the surface of the underlying floor, making the surface of the board body flat.

DETAILED DESCRIPTION

[0030] In order to have a further understanding and recognition of the features and effects achieved by the present invention, only embodiments and detailed descriptions are provided, as follows:

[0031] See also Figure 1 and Figure 2 , which are a three-dimensional schematic diagram and a side schematic diagram of the artificial floor of the present invention. As shown in the figure, the present embodiment provides an artificial floor 1, which includes a plate body 11, and the plate body 11 is used to be laid on the bottom floor 2, and the bottom floor 2 here may be a ground or floor surface. The plate body 11 has a variety of styles, such as various simulated floors such as imitation linen floor, imitation wood floor (Wood Plastic Composites, WPC) or imitation stone floor (Stone Plastic Composites, SPC), and the user can select the required style of floor according to the needs. The plate body 11 and the bottom floor 2 can be fixed by adhesive bonding, or the plate bodies 11 can be spliced ​​and buckled with each other and directly laid on the bottom floor 2.

[0032] Furthermore, one surface of the plate body 11 has a cushioning portion 111. When the plate body 11 is laid on the subfloor 2, the surface of the plate body 11 having the cushioning portion 111 is in contact with the subfloor 2. The cushioning portion 111 of the plate body 11 has a foamed body with a plurality of closed pores, wherein the cushioning portion 111 is foamed by electron bridging for many times. There are many ways of electron beam irradiation, which can cause differences in electron beam irradiation by controlling the irradiation dose and irradiation depth, thereby controlling the irradiated cushioning portion 111 to produce different bridging modes. The process of electron bridging using electron beam irradiation is simple and fast, which can eliminate the hazards of organic chemicals, reduce the manufacturing cost of adding cross-linking agents, and shorten the test time of the bridging reaction conditions of the cushioning portion 111. The foaming method using an electron beam can improve the physical properties of the cushioning portion 111, and the foaming uniformity of the cushioning portion 111 is better.

[0033] Furthermore, the other surface of the plate body 11 has a surface portion 113, and the surface portion 113 is disposed on the pad portion 111. The surface portion 113 and the pad portion 111 are bonded by heating or gluing, wherein the heating bonding method includes infrared heating or flame heating, etc. Taking the flame heating bonding method as an example, the flame bonding method is that the pad portion 111 and the surface portion 113 are mutually burned by a high-temperature flame, and there is no problem of adhesive residue. In the flame bonding process, because the majority of the closed pores of the pad portion 111 are burned, the air in these closed pores is consumed (i.e., the effect is similar to pumping air), and these closed pores form a vacuum-like state, thereby reducing the medium as a heat convection and heat conduction, and can also reduce the vibration transmission of sound through the medium, thereby achieving heat insulation and sound insulation effects.

[0034] In addition, the surface portion 113 of the board body 11 has a surface material 1131. The surface material 1131, plastic material and other materials are mixed, and the mixed material is heated and pressurized before being molded to form the board body 11. The surface material 1131 can be wood powder, stone powder or plant fiber. The surface portion 113 has a wood grain, stone grain, carpet grain, metal grain or other grain design, and the above grain is selected according to the needs of the user and is not limited.

[0035] Please also read Figure 3 , which is a schematic diagram of the side combination of the artificial floor of the present invention. As shown in the figure, in this embodiment, the wear resistance of the surface portion 113 of the plate body 11 is poor, and the hardness of the surface portion 113 is greater than the hardness of the cushion portion 111, wherein the hardness difference range between the surface portion 113 and the cushion portion 111 is 10 to 75 degrees or Shore A5 to 60 degrees measured by the spring-type ASKER-C type specified in the JIS-S6050 and SRIS-0101 hardness standards. In addition, the hardness of the cushion portion 111 changes with the hardness of the surface portion 113. If the hardness of the surface portion 113 is greater, the hardness of the cushion portion 111 is greater, and the hardness of the cushion portion 111 is less than or equal to the hardness of the surface portion 113. The cushion portion 111 has a tough texture, and the cushion portion 111 can be used as a structure to protect and support the surface portion 113.

[0036] In addition, the thickness of the pad portion 111 ranges from 0.01 mm to 15 mm, and the thickness of the pad portion 111 is adjusted according to the requirements of the construction environment (such as the hardness of the surface portion 113 ). In this way, the pad portion 111 can support and cushion the surface portion 113 .

[0037] See also Figure 4 and Figure 5 , Figure 4 is a side view of the liner portion of the present invention; Figure 5It is a side schematic diagram of the cushion part of the present invention. As shown in the figure, in some embodiments, the cushion part 111 can be a continuous foamed sheet, which is expanded by heating in a foaming furnace and then formed by rolling and cooling by a cooling wheel. After rolling, the two sides (i.e., the top surface and the bottom surface) of the cushion part 111 are pressed toward the center of the cushion part 111, and two outer layers are formed on the outer surface of the cushion part 111. Therefore, in the side view of the rolled cushion part 111, the cushion part 111 shows a three-layer structure, which is the first outer layer 1110, the inner layer 1111 and the second outer layer 1112 in sequence. In some embodiments, the thickness of the outer layer of the cushion part 111 can be almost a constant value related only to the compressive stress of the rolling process. In some embodiments, the thickness of the outer layer of the cushion part 111 can be 0.05 to 1 mm. However, the above thickness range is only an example, and the present invention is not limited thereto. In some embodiments, the thickness of the outer layer of the cushion part 111 can be less than 0.05 mm. For example, the thickness may be 0.04 mm, 0.03 mm, 0.02 mm or less.

[0038] After rolling, the diameter of the closed pores on the outer surface of the cushion portion 111 (i.e., the first outer layer 1110 and the second outer layer 1112) is reduced, and the density and hardness of the outer surface of the cushion portion 111 (i.e., the first outer layer 1110 and the second outer layer 1112) are increased. In this way, the support force of the cushion portion 111 can be effectively improved, and the inner layer 1111 can be effectively protected by the first outer layer 1110 and the second outer layer 1112.

[0039] On the other hand, the diameter of the closed pores at the center of the lining portion 111 (ie, the inner layer 1111) remains unchanged after rolling, and its density and hardness also remain unchanged. Therefore, the inner layer 1111 still has excellent cushioning performance.

[0040] By forming the above three-layer structure, the protection and support of the pad part 111 are effectively enhanced while maintaining the cushioning property.

[0041] In some embodiments, the thickness of the pad portion 111 is preferably 0.05 mm to 5 mm, more preferably 0.3 mm to 2 mm, and even more preferably 1.5 mm. When the thickness of the pad portion 111 is 1.5 mm, the thicknesses of the first outer layer 1110 and the second outer layer 1112 are 0.3 mm, respectively, and the thickness of the inner layer 1111 is 0.9 mm. In addition, the total density of the pad portion 111 is 45 kg / m 3 The density of the first outer layer 1110 and the second outer layer 1112 are respectively about 54 kg / m 3 The density of the inner layer 1111 is 43kg / m 3 .

[0042] In some embodiments, the density range and hardness range of the cushion portion 111 , the diameter range of the closed pores, and the 25% compression force range of the cushion portion 111 are shown in Table 1.

[0043] Table 1 <![CDATA[Total density (kg / m 3 )]]> 20-300 Closed pore diameter (mm) 0.10-2.00 Hardness(degree)(SRIS-0101) 10-75 <![CDATA[25% compression stress of the gasket part 111 (kgf / cm 2 )]]> 0.10-5.00

[0044] In some embodiments, the thickness of the first outer layer and / or the second outer layer is 0.05 mm to 1.0 mm, and the thickness of the inner layer is 0.1 mm to 15 mm. In some embodiments, the density of the first outer layer and / or the second outer layer is 25 kg / m 3 Up to 250kg / m 3 The density of the inner layer is 20kg / m 3 Up to 200kg / m 3 In some embodiments, the diameter of the closed pores is 0.1 mm to 2.00 mm.

[0045] In addition, taking some embodiments of the present invention as specific examples, the density and hardness of the cushion part 111, the diameter of the closed pores, and the 25% compression force of the cushion part 111 of these examples are shown in Table 2. However, the following numerical values ​​are only examples, and the present invention is not limited thereto.

[0046] Table 2

[0047] In some embodiments, when the artificial floor is stacked and placed during transportation, the bottom of the cushion portion 111 (i.e., the second outer layer 1112) will contact the upper surface of another artificial floor. In this case, the total density may preferably be 30-60 kg / m 3 The higher density outer layer (i.e., the first outer layer 1110 / the second outer layer 1112) prevents the cushion portion 111 from being damaged by friction with the texture of another artificial floor, and also prevents the inner layer 1111 of the cushion portion 111 from being permanently deformed by the weight of other artificial floors. In addition, the soft cushioning of the inner layer 1111 enables the lower surface of the cushion portion 111 (i.e., the second outer layer 1112) to deform in response to the texture, maintain the distance between the subfloor and the surface portion 113, and protect the texture of the surface portion 113 from being damaged by friction with the subfloor.

[0048] In some embodiments, when the artificial floor is laid on concrete or cement mortar, even if the surface is cleaned, there is still a high unevenness between the artificial floor and the concrete or cement mortar due to gravel. Under the protection of the outer layer, the inner layer 1111 of the cushion part 111 is squeezed and deformed but not damaged, and still has a buffering performance. In addition, the low-density inner layer 1111 can be deformed to match the uneven surface, so that the surface part 113 can remain level.

[0049] In some embodiments, when the artificial floor is laid on a smooth surface, the total density may preferably be 80-300 kg / m 3 The pad portion 111 has a force of 1.0-4.0 kgf / cm 2 25% compressive stress. Under this condition, the artificial floor has good support and can carry heavier objects.

[0050] It should be noted that the present invention is not limited to the above description. In some embodiments, the pad portion 111 is composed of at least two types of foams. For example, the first outer layer and / or the second outer layer may use high-density foam, the inner layer may use another type of low-density foam, and the first outer layer, the second outer layer, and the inner layer may be bonded to each other by an adhesive. In other words, the present invention is not limited to the method for forming the three-layer structure, and any three-layer structure formed by any method may be used.

[0051] Please also read Figure 6 and Figure 7 , which is a stacking schematic diagram of the artificial floor of the present invention and another stacking schematic diagram. As shown in the figure, in this embodiment, the board body 11 is transported in a stacked state, and the stacking method can be divided into upper and lower stacking placement or left and right arrangement placement. During the transportation process of the stacked board body 11, the texture of the surface portion 113 of the board body 11 is easily scratched or damaged due to the friction of the board body 11 due to the up and down vibration or left and right shaking during transportation. Therefore, when the board body 11 of this embodiment is stacked on another board body 11, the pad portion 111 of the board body 11 contacts the surface portion 113 of the other board body 11. The pad portion 111 can buffer the vibration or shaking of the surface portion 113 of the board body 11, thereby protecting the surface of the board body 11.

[0052] Please also read Figure 8 and Fig. 9, which is a combined schematic diagram of the artificial floor of the present invention and another combined schematic diagram. As shown in the figure, in this embodiment, the peripheral side of the plate body 11 further includes a plurality of connecting members 115, and the plurality of connecting members 115 include a first connecting member 1151 and a second connecting member 1153. The first connecting member 1151 is arranged on one side of the plate body 11, and the second connecting member 1153 is arranged on the other side of the plate body 11. In this embodiment, when the plate body 11A is spliced ​​with another plate body 11B, the first connecting member 1151 of the plate body 11A is connected to the second connecting member 1153 of the other plate body 11B. The first connecting member 1151 is a convex block structure, and the second connecting member 1153 is a groove structure. The first connecting member 1151 is embedded in the second connecting member 1153, so that the plate body 11A and the other plate body 11B are connected and fixed to each other.

[0053] As mentioned above, the first connecting member 1151 is disposed on one side of the surface portion 113 and away from the pad portion 111. The second connecting member 1153 is disposed on the other side of the surface portion 113 and adjacent to the pad portion 111. The pad portion 111 further extends to the bottom of the second connecting member 1153. In this way, the pad portion 111 can be used as a supporting structure supported under the second connecting member 1153, thereby protecting the second connecting member 1153. As for the structure of the second connecting member 1153 and the pad portion 111, on the one hand, it enhances the supporting force of the second connecting member 1153 connected to one side of the plate body 11, so that the second connecting member 1153 is not easily broken due to external force during transportation. On the other hand, most of the plates 11 are to be laid on the base floor 2. If the base floor 2 has an uneven structure, the uneven structure will affect the second connecting member 1153 of the base floor 2 during the process of splicing and laying the plates 11, resulting in the breakage of the second connecting member 1153. Therefore, the second connecting member 1153 of this embodiment also uses the pad portion 111 as a protective structure for support and buffering, thereby reducing the impact of the uneven structure on the second connecting member 1153.

[0054] In addition, the traditional laying method of artificial flooring mostly adopts the method of laying a large area of ​​cushion layer first, and then splicing the floorboards on the cushion layer to form the floor surface layer. If the base floor is uneven and a large area of ​​cushion layer is laid directly, it will cause the entire cushion layer to deform simultaneously with the base floor. Laying floorboards in this case will easily cause larger gaps between floorboards on the floor surface layer, and it is impossible to make the floorboards completely fit on the cushion layer, which will easily cause the floorboards to fall off. Therefore, when the plate bodies 11 of the artificial floor 1 of the present embodiment are spliced, each plate body 11 is an independent individual directly laid on the bottom floor 2, and the bottom surface of the plate body 11 has a cushioning portion 111, so that the cushioning portion 111 of the plate body 11 produces independent local deformation to the unevenness of the bottom floor 2, and because each plate body 11 is an independent individual, there is also a gap between each other to provide each cushioning portion 111 with a space for adjustable deformation, thereby improving the flexibility of the cushioning portion 111 of the plate body 11 to deform, so as to reduce the unevenness of the plate body 11. In this way, the plate body 11 can better adapt to the uneven structure of the bottom floor 2. Furthermore, the installation method of the existing floor structure can also be improved, and it is no longer necessary to lay the cushioning layer first and then the floor layer for two times.

[0055] In summary, the present invention provides an artificial floor, which includes a plate body, and the bottom of the plate body has a cushioning portion, and the cushioning portion is used to be laid on the subfloor. The plate body can be various types of simulated floors such as imitation linen floors, imitation wood floors or imitation stone floors. The wear resistance of the above-mentioned various simulated floors is poor. Vibration or shaking during transportation may cause collision or friction between floors, which may easily cause damage to the surface of the floor. Furthermore, the subfloor may also have an uneven surface, which may affect the flatness of the surface on which the plate body is laid. Therefore, the cushioning portion of the plate body can not only serve as a buffer during the transportation process to protect the collision and friction between the plate bodies, but also prevent the breakage of the connector. In addition, the cushioning portion can also be used as a local deformation to fit the surface of the subfloor.

[0056] The above-mentioned embodiments illustrate the implementation of one inner layer. The following embodiments illustrate the implementation of multiple inner layers. The padding portion illustrated in the following embodiments may be a continuous foamed sheet, which is heated and expanded in a foaming furnace after multiple electron bridges, and then calendered by a cooling wheel. By subjecting it to multiple different electron irradiations, a foamed body with different functions and the same material and integrally formed can be obtained.

[0057] Please refer to Fig.10, which is a side view of another embodiment of the cushion part of the artificial floor of the present invention, the cushion part 211 shows a five-layer structure, which is the first outer layer 2111, the first inner layer 2211, the second inner layer 2212, the third inner layer 2213 and the second outer layer 2112 in sequence. This five-layer structure is formed by adjusting the electron radiation for many times to produce multiple layers of foams with different bridging degrees in the internal structure of the foam, and then cooling and molding by a cooling wheel to form a foam with a dense surface but different bridging degrees. In addition, by adjusting the bridging degree of the inner layer, that is, the first inner layer 2211≧the third inner layer 2213≧the second inner layer 2212, the wear resistance and crush resistance of the outer layer of the skin are strengthened to protect the surface of the board and the connecting parts from friction damage during transportation.

[0058] The following table is an exemplary description of the inner layer bridging degree:

[0059] In this embodiment, the thickness of the first outer layer 2111 and / or the second outer layer may be 0.1% to 5% of the overall thickness of the pad portion, the thickness of the first inner layer 2211 may be 0% to 40% of the overall thickness, the thickness of the second inner layer 2212 may be 10% to 99.8% of the overall thickness, and the thickness of the third inner layer 2213 may be 0% to 40% of the overall thickness. However, the above thickness ranges are only examples, and the present invention is not limited thereto.

[0060] In this embodiment, the outer layer has compactness, so whether it is stacked or attached to a flat and smooth floor base, it can be tightly attached to reduce sliding. When it is transported, it can also effectively protect the surface texture of the board layer from being worn. When attached to a floor base with a rough surface or a floor base with residual gravel particles, in addition to being able to deform the foaming layer of the five-layer structure to make the board layer on the opposite side horizontal, the compactness of the outer layer can also make it firmly attached and not easy to move, and it can also strengthen it when subjected to external pressure so that the surface is not damaged by pressure due to the uneven contact surface, resulting in a decrease in insulation and support.

[0061] Please refer to Fig.11, which is a side view of another embodiment of the cushion part of the artificial floor of the present invention, the cushion part 311 shows a five-layer structure, which is the first outer layer 3111, the first inner layer 3211, the second inner layer 3212, the third inner layer 3213 and the second outer layer 3112. In this embodiment, after adjusting the electron radiation for many times, the internal structure of the foam body produces multiple layers of foam bodies with different bridging degrees, and the thickness of the first inner layer 3211 and the third inner layer 3213 is increased by adjustment, and then cooled and formed by a cooling wheel, a foam body with a dense surface but multiple layers of different densities and bridging degrees can be obtained. By adjusting the bridging degree of the inner layer, that is, the first inner layer 3211≧the third inner layer 3213≧the second inner layer 3212, the wear resistance and crush resistance of this embodiment are better than those of the above-mentioned embodiments.

[0062] The following table is Fig.11 Examples of bridging degree of embodiments:

[0063] This embodiment can be used for floor bases with large surface roughness or slight slope. Because the bridging degree of the second inner layer 3212 is less than that of the first inner layer 3211, when a pressure is applied to the board layer, due to its bridging degree, the second inner layer 3212 will first deform so that the board layer can appear flat, and because the density of the outer skin layer is greater than that of the first inner layer 3211, when it contacts with a floor base with large surface roughness, the inner layer can be protected so that the foam body will not be damaged by the protrusions due to contact with the uneven floor surface. In addition, when it is bonded to a floor base with a slight slope, there is no need for special treatment at the angles and it can be directly laid. The deformation of the second inner layer 3212 can be used to make the surface of the board layer smooth. Then, by increasing the proportion of the first inner layer 3211 and the third inner layer 3213, the wear resistance and crush resistance are enhanced, and the overall support can be strengthened, so that it can achieve the same supporting force at the angles and its surroundings as when it is laid flat, and no abnormal noise will be generated during long-term use.

[0064] Please refer to Fig.12 , which is a side view of another embodiment of the cushion part of the artificial floor of the present invention, the cushion part 411 shows a five-layer structure, which is the first outer layer 4111, the first inner layer 4211, the second inner layer 4212, the third inner layer 4213 and the second outer layer 4112. After adjusting the electron radiation for many times, the internal structure of the foam body produces two layers of foam bodies with different bridging degrees, and the proportion of the second inner layer 4212 is increased by adjustment, and then cooled and formed by the cooling wheel, a foam body with a dense surface but multiple layers of different bridging degrees can be obtained; the bridging degree decreases layer by layer, that is, the second inner layer 4212≧the first inner layer 4211≧the third inner layer 4213. The configuration of this embodiment can obtain better support than the above embodiment.

[0065] The following table is Fig.12 Examples of bridging degree of embodiments:

[0066] This embodiment can be used for those requiring high support or thinner thickness, and can also be used for floor bases with slight height differences on the floor surface. The deformation of the first inner layer 4211 and the third inner layer 4213 can reach the level of the board layer, but the high support of the second inner layer 4212 can achieve flatness without depressions and protrusions.

[0067] Please refer to Fig.13 , which is a side view of another embodiment of the cushioning part of the artificial floor of the present invention, the cushioning part 511 shows a three-layer structure, which is the first composite layer 5111, the inner layer 5212, and the second composite layer 5112. After adjusting the electron radiation multiple times, the internal structure of the foam body produces multiple layers of foam bodies with different bridging degrees, and by adjusting the first inner layer and the third inner layer to reduce the proportion to less than or the same as the surface outer layer, this embodiment can be obtained, that is, the thickness of the first inner layer and the third inner layer is less than or equal to the first outer layer and the second outer layer, so that the first inner layer and the first outer layer are integrated into the first composite layer, the third inner layer and the second outer layer are integrated into the second composite layer, and the inner layer 5212 is equivalent to the aforementioned second inner layer. In terms of bridging degree, the bridging degree decreases layer by layer, that is, the first composite layer 5111≧the second composite layer 5112>the inner layer 5212. The bridging degree configuration of this embodiment can obtain better wear resistance than the above-mentioned embodiment.

[0068] The following table is Fig.13 Examples of bridging degree of embodiments:

[0069] In some embodiments, the thickness of the first layer 5111 and the second layer 5112 may account for 1% to 10% of the overall thickness, and the thickness of the inner layer 5212 may account for 20% to 98% of the overall thickness.

[0070] Compared with the aforementioned embodiment, the first ply and the second ply in this embodiment have better density, and not only have better wear resistance, but also have a good contact surface with both the board and the base floor due to the density of the surface, and have better isolation.

[0071] Figures 10 to 13The foam body illustrated in the embodiment is a one-piece foam body with different bridging degrees obtained by adjusting the electron radiation multiple times, and because of its surface density, it can effectively alleviate the problem of damage to the board caused by wear, crushing and penetration; and because it is an one-piece foam body, the different contents required by the customer can be achieved by adjusting the inner layer of the foam with different bridging degrees, and no matter how the inner layer of the foam is adjusted, its surface has a dense surface layer that can strengthen the adhesion, wear resistance and protection of the dense surface layer of the foam inner layer, so it can meet the needs of the client and protect the board layer.

[0072] The following table shows the bridging degree of the inner layer of the liner:

[0073] The number and thickness of the inner layer in the above embodiment can be determined and adjusted according to the needs. In addition, the number and relative position of the bridge are not fixed, it can be upward, downward or centered, and the number of layers is not limited to five or three layers, and can be adjusted according to the situation.

After adjusting the electron radiation multiple times to make the internal structure of the foam body produce multiple layers of foam bodies with different bridging degrees, and by adjusting to increase the proportion of the first inner layer 6211, and then reduce it in sequence, the following can be obtained: Fig.14 The bridging degree decreases layer by layer, that is, the first inner layer 6211≧the second inner layer 6212≧the third inner layer 6213.
